    Abstract [en]

    Background: Intake of a balanced school lunch has been associated with healthier eating habits in general, for example better meal planning and healthier snacks.Objective: To investigate the lunch habits of pupils during school days, in one secondary school in Arjeplog and Arvidsjaur, respectively.Method: A survey was handed out to 110 pupils in 8th and 9th grade in Arjeplog and Arvidsjaur. The survey asked for the pupils’ lunch habits, intake of high sugary and fast food as well as fruit and vegetables.Results: Four out of five pupils ate school lunch daily (77 %, n=84). Less than every five of these pupils ate a balanced school lunch according to the Swedish food administration’s definition (17 %, n=14). More pupils ate a balanced school lunch in Arvidsjaur (p=0,009). The most chosen reason to eat school lunch was to satisfy ones hunger, and for not to eat that they didn’t like the food. Among non-school lunch eaters, it was most common to eat fast food instead. Of all the pupils, 62 % (n=67) thought that the school lunch was lacking main course options. Candy was eaten at least two days per week by 53 % (n=57) of the pupils. Among balanced school lunch eaters, fruit and vegetables where consumed more frequently than among those eating an unbalanced school lunch (p=0,023; p<0,001, respectively). Vegetables where eaten daily by 37 % (n=15) of the girls and 17 % (n=11) of the boys (p=0,025).Conclusion: The eating habits during lunchtime in Arjeplog and Arvidsjaur indicate less healthy dietary habits in general. There are tendencies of less healthy food habits in Arjeplog. When deciding whether to eat school lunch or not, taste and quality of the food is of major importance. Investment in school meals is an important investment in public health.

    The sedimentary and remote-sensing reflection of biomass burning in Europe2018In: Global Ecology and Biogeography, ISSN 1466-822X, E-ISSN 1466-8238, Vol. 27, no 2, p. 199-212Article in journal (Refereed)
    Abstract [en]

    Aim: We provide the first European-scale geospatial training set relating the charcoal signal in surface lake sediments to fire parameters (number, intensity and area) recorded by satellite moderate resolution imaging spectroradiometer (MODIS) sensors. Our calibration is intended for quantitative reconstructions of key fire-regime parameters by using sediment sequences of microscopic (MIC from pollen slides, particles 10-500 mu m) and macroscopic charcoal (MAC from sieves, particles > 100 mu m). Location: North-south and east-west transects across Europe, covering the mediterranean, temperate, alpine, boreal and steppe biomes. Time period: Lake sediments and MODIS active fire and burned area products were collected for the years 2012-2015. Methods: Cylinder sediment traps were installed in lakes to annually collect charcoal particles in sediments. We quantitatively assessed the relationships between MIC and MAC influx (particles/cm(2)/year) and the MODIS-derived products to identify source areas of charcoal and the extent to which lake-sediment charcoal is linked to fire parameters across the continent. Results: Source area of sedimentary charcoal was estimated to a 40-km radius around sites for both MIC and MAC particles. Fires occurred in grasslands and in forests, with grass morphotypes of MAC accurately reflecting the burned fuel-type. Despite the lack of local fires around the sites, MAC influx levels reached those reported for local fires. Both MIC and MAC showed strong and highly significant relationships with the MODIS-derived fire parameters, as well as with climatic variation along a latitudinal temperature gradient. Main conclusions: MIC and MAC are suited to quantitatively reconstructing fire number and fire intensity on a regional scale. However, burned area may only be estimated using MAC. Local fires may be identified by using several lines of evidence, e.g. analysis of large particles (> 600 mu m), magnetic susceptibility and sedimentological data. Our results offer new insights and applications to quantitatively reconstruct fires and to interpret available sedimentary charcoal records.

    Abstract [en]

    Background Establishing good eating habits during childhood are important since these lay the foundation for the future. Having a balanced and healthy diet is associated with a better learning ability. Research shows differences in intake of energy and nutrients between boys and girls.

    Objective The purpose of this study was to investigate possible differences between boys and girls referring intake of school lunch and to compare them to Nordic Nutrition Recommendations (NNR) with a focus on content of energy and nutrients.

    Method This study was established through a partnership with ProMeal. Data was collected during five days through a weighed and photographed food record of school lunch among 29 children in the 5th grade. The participants’ portions of food were calculated concerning contents of energy and nutrients through the computer program DietistNet. Data was statistically analyzed in order to detect differences in intake of energy and nutrients between the sexes. A comparison between the participants’ energy and nutrient intake and the NNR was made.

    Results This research showed no statistical significant difference between boys’ and girls’ intake of energy (p=0,226). Regardless of sex the participants’ median intake of energy was lower than the estimated energy demand for the age group according to NNR. There was no statistical significant difference between boys and girls concerning the intake of energy from macronutrients. The share of energy from carbohydrates, protein and fat was relatively even distributed between the sexes. In comparison boys had a significantly higher intake of dietary fiber (p=0,008), iron (p=0,037) and vitamin C (p=0,034) than girls. 

    Conclusion Overall the participants had a noteworthy low intake of energy and micronutrients in relation to the estimated demands and recommendations of NNR. During five days there was no statistical significant difference between boys and girls concerning intake of energy. Further research is needed.

    Saccharification of lignocellulosic biomasses via ionic liquid pretreatment2016In: Industrial crops and products (Print), ISSN 0926-6690, E-ISSN 1872-633X, Vol. 92, p. 336-341Article in journal (Refereed)
    Abstract [en]

    The current work focuses on the pretreatment efficiency of ILs combined with heat for woody biomass consisting of spruce, birch and pine as well as winter wheat straw. The latter was investigated as a comparison and with the aim to enhance its digestibility during enzymatic hydrolysis whereby the influence of IL-treatment to cellulose resistance for hydrolysis was investigated. Considering the wood species, the most common and industrially important wood species in Northern Europe were chosen in the present work and the goal was to obtain fermentable sugars and their degradation product, i.e. 5-hydroxymethylfurfural (5-HMF), which is known valuable platform chemical. Further, the differences in the yields of IL-obtainable carbohydrates between these species were studied. The highest sugar yields were obtained to glucose in the case of spruce and arabinose in the case of pine sapwood, 12.07 and 7.72 mmol/L, respectively. The highest 5-HMF yield was obtained for spruce heartwood (9.18 mmol/L) with longer treatment time, such as 100h. However, regarding woody biomass, the present work was focused more on the study and analysis of the IL-containing liquid part, wood hydrolysate, after IL-treatment aiming to answer the analysis challenges related to this fraction.

    Abstract [en]

    Background In-between meals can include anything consumed between breakfast, lunch and dinner. There are no explicit recommendations about in-between meals in Sweden. Dietary habits are affected by social norms and peers. Usually dietary habits change during college or university. The eating habits created during this time is often kept for the future.

    Objective Examine students’ ideas about and attitudes towards in-between meals.

    Method Eight semi-structured individual interviews were held with students from Swedish University of Agricultural Sciences and Umeå University. The participants were recruited by the authors at both Universities. The interviews were recorded and transcribed word by word. The data collection was analyzed using a qualitative content analysis.

    Results The participants had different views about in-between meals. Some believed in-between meals was a good thing while others thought it was pointless. Lack of time and bad planning were the biggest reasons not to have in-between meals. The participants described that their friends and acquaintances affected their in-between meals. The participants believed that a person’s body shape and what they ate affected how they saw that person. Some of the female participants brought up social pressure about weight and how it restrained their food choices.

    Conclusion Individuals greatly differed in their opinions towards in-between meals and when it should be consumed. Assortment, social norms and peers was affecting student's thoughts and action towards in-between meals. More research is required to see if there is a need for general advice about in-between meals and how they should be mediated. More research is also required about social norms and in-between meals, but also about their health benefits.

    Integrative analysis of three RNA sequencing methods identifies mutually exclusive exons of MADS-box isoforms during early bud development in Picea abies2018In: Frontiers in Plant Science, ISSN 1664-462X, E-ISSN 1664-462X, Vol. 9, article id 1625Article in journal (Refereed)
    Abstract [en]

    Recent efforts to sequence the genomes and transcriptomes of several gymnosperm species have revealed an increased complexity in certain gene families in gymnosperms as compared to angiosperms. One example of this is the gymnosperm sister Glade to angiosperm TM3-like MADS-box genes, which at least in the conifer lineage has expanded in number of genes. We have previously identified a member of this subclade, the conifer gene DEFICIENS AGAMOUS LIKE 19 (DAL19), as being specifically upregulated in cone-setting shoots. Here, we show through Sanger sequencing of mRNA-derived cDNA and mapping to assembled conifer genomic sequences that DAL19 produces six mature mRNA splice variants in Picea abies. These splice variants use alternate first and last exons, while their four central exons constitute a core region present in all six transcripts. Thus, they are likely to be transcript isoforms. Quantitative Real-Time PCR revealed that two mutually exclusive first DAL19 exons are differentially expressed across meristems that will form either male or female cones, or vegetative shoots. Furthermore, mRNA in situ hybridization revealed that two mutually exclusive last DAL19 exons were expressed in a cell-specific pattern within bud meristems. Based on these findings in DAL19, we developed a sensitive approach to transcript isoform assembly from short-read sequencing of mRNA. We applied this method to 42 putative MADS-box core regions in P abies, from which we assembled 1084 putative transcripts. We manually curated these transcripts to arrive at 933 assembled transcript isoforms of 38 putative MADS-box genes. 152 of these isoforms, which we assign to 28 putative MADS-box genes, were differentially expressed across eight female, male, and vegetative buds. We further provide evidence of the expression of 16 out of the 38 putative MADS-box genes by mapping PacBio Iso-Seq circular consensus reads derived from pooled sample sequencing to assembled transcripts. In summary, our analyses reveal the use of mutually exclusive exons of MADS-box gene isoforms during early bud development in P. abies, and we find that the large number of identified MADS-box transcripts in P. abies results not only from expansion of the gene family through gene duplication events but also from the generation of numerous splice variants.

    The Paradox of Self-Fertile Varieties in the Context of Self-Incompatible Genotypes in Olive2019In: Frontiers in Plant Science, ISSN 1664-462X, E-ISSN 1664-462X, Vol. 10, article id 725Article, review/survey (Refereed)
    Abstract [en]

    Olive, representing one of the most important fruit crops of the Mediterranean area, is characterized by a general low fruit yield, due to numerous constraints, including alternate bearing, low flower viability, male-sterility, inter-incompatibility, and self-incompatibility (SI). Early efforts to clarify the genetic control of SI in olive gave conflicting results, and only recently, the genetic control of SI has been disclosed, revealing that olive possesses an unconventional homomorphic sporophytic diallelic system of SI, dissimilar from other described plants. This system, characterized by the presence of two SI groups, prevents self-fertilization and regulates inter-compatibility between cultivars, such that cultivars bearing the same incompatibility group are incompatible. Despite the presence of a functional SI, some varieties, in particular conditions, are able to set seeds following self-fertilization, a mechanism known as pseudo-self-compatibility (PSC), as widely reported in previous literature. Here, we summarize the results of previous works on SI in olive, particularly focusing on the occurrence of self-fertility, and offer a new perspective in view of the recent elucidation of the genetic architecture of the SI system in olive. Recent advances in research aimed at unraveling the molecular bases of SI and its breakdown in olive are also presented. The clarification of these mechanisms may have a huge impact on orchard management and will provide fundamental information for the future of olive breeding programs.

    Abstract [en]

    Background: In Sweden 35% of children with separated parents live in equally shared care on an every-other-week basis. There is a lack of studies in research addressing equally shared care and dietary concerns. It is a family situation like no other: neither a single-parent household, nor a single-member household, nor cohabitation in the usual sense. Life changes affect dietary habits. The shift to shared custody can be considered such a change and is therefore worth investigating.

    Objective: The aim was to assess how parents living in shared-care situations experienced dietary concerns, and to examine what challenges foodwise such a family construct may evoke.

    Method: Four men and three women were interviewed using a semi-structural interview guide about their dietary concerns as parents with equally shared care of children. Collected data from the interview were analysed with a qualitative content analysis method.

    Result: There were some special qualities in this family situation that are not found in other household settings. Most significant was the duality in the household structure: there was the importance of continued cooperation with the other parent, time and food were more important with the children than without them, and there was a sense of lack when the children were not there. All informants, regardless of gender, expressed that they spent much more time and care preparing meals during weeks with the children.

    Conclusion: There was a duality in the way dietary concerns were valued between weeks with and without children. There exists an emotional as well as a practical difference between the weeks which affect diet and possibly health. Gender roles of the parents are seemingly being equalized. Equally shared care differs enough as a household setting to warrant more studying to understand how parents are affected by this way of living.

    Introducing a framework for good and adaptive governance: an application to fire management planning in Canada's boreal forest2013In: Forestry Chronicle, ISSN 0015-7546, Vol. 89, no 5, p. 664-674Article in journal (Refereed)
    Abstract [en]

    Planning for and managing disturbances in protected areas requires governance arrangements that are both adaptive to changing conditions and effective in dealing with multiple challenges. This paper presents a framework composed of principles and criteria of good and adaptive governance that pays attention to inclusiveness, responsibility, fairness, strategic vision, performance orientation, and adaptiveness. The framework was empirically tested on fire management planning in Prince Albert National Park, Saskatchewan, Canada, involving interactions between Parks Canada and Saskatchewan Environment. Our results suggest that while the principle of performance orientation was upheld, principles such as inclusiveness and adaptiveness were only partially supported. Additional testing beyond fire management planning can help determine the utility of the framework for other environmental management situations.

    Abstract [en]

    Background: Depression is common, and research shows that diet influences our well-being. Interest in the relationship between diet and depression has increased, but important information about dietary habits when depressed is still missing.

    Objective: The aim of this study was to identify dietary habits when feeling downhearted or depressed among individuals over age 15 and relate results to the Swedish Nutrition Recommendations, to see if these individuals are following the recommendations as well as indication of possible areas of improvement.

    Method: A quantitative method in the form of a questionnaire survey was chosen, focusing on six areas. The questionnaire was distributed through health care providers and was also available on the Internet. Collected data were analyzed using SPSS Statistics Desktop V22.

    Results: Half of the respondents felt that they had an unhealthy diet. Less than half followed the Swedish Nutrition Recommendations of three larger meals per day. The majority ate breakfast and consumed larger meals regularly. The median consumption of fish and fatty fish was 0.75 times per week. The Vitamin-D rich products consumed most frequently were milk and sour milk/yogurt, however, the enriched option wasn’t always chosen. Difficulty in reaching recommendations on 500g of fruit and vegetables per day could be indicated, since only four respondents had a consumption frequency of five times a day or more. Consumption frequency of unsaturated fat sources such as fish, avocado, nuts and seeds and requested fats as margarine, oil and butter were low.

    Conclusion: The study shows a low consumptions frequency of fruit and vegetables, vitamin D-rich products and the studied fat sources fish, avocado, nuts and seeds, margarine, oil and butter in comparison with the Swedish Nutrition Recommendations. This shows areas of improvement, but the results are not generalizable to the target audience. It is desirable to have more studies to draw conclusions about the diets with downheartedness or depression.

    Adaptation to climate change?: Why business-as-usual remains the logical choice in Swedish forestry2018In: Global Environmental Change, ISSN 0959-3780, E-ISSN 1872-9495, Vol. 48, p. 76-85Article in journal (Refereed)
    Abstract [en]

    The two latest IPCC assessment reports have concluded that knowledge is not sufficient for inducing action on climate change. This study problematizes the issue of going beyond business-as-usual through a study of the forestry sector in Sweden, which is a large economic sector and could be expected to be an early adapter, given that newly planted forest may stand some 70-90 years into the future. Therefore resources, economic motivation in the longer term and environmental foundations for early adaptation action could be expected to exist. This study draws upon the Foucauldian conceptualization of governmentality to explain the particular institutional logics that nevertheless lead to business-as-usual arguments dominating discussion on adaptation in the case of Swedish forestry. The study emphasizes that adaptation must be seen as steered and limited by existing institutional, social system logics, rather than by externally defined "rational" motivations. Efforts on adaptation to climate change must thus be considered in relation to, and seek to change, existing institutionally based motivational and incentive structures, and must thus be conceived through social rather than environmental logics. In fact, social logics may even define the types of actions that may be regarded as adaptations.

    Service logics and strategies of Swedish forestry in the structural shifts of forest ownership: challenging the "old" and shaping the "new"2019In: Scandinavian Journal of Forest Research, ISSN 0282-7581, E-ISSN 1651-1891, Vol. 34, no 6, p. 508-520Article in journal (Refereed)
    Abstract [en]

    Sweden is one of the most forested countries in Europe, and it has one of the highest shares of productive forest. Production in forestry is largely reliant on the private non-industrial forest owners, who own half of the forest land. As in many countries, however, forest ownership is changing towards a higher extent of urban, female or non-forestry-background owners. This poses a challenge for the forestry services sector, mainly forest owners' associations and companies, but also broadly the sector at large. By exploring the sales and marketing processes, this paper analyses the service logics and strategies of Swedish forestry under changing forest ownership, drawing on an interview study covering all the large actors in the Swedish forestry sector. The study illustrates an increased focus of forestry organizations on services from a strategic and managerial perspective, in customer-oriented relationship development and in value creation and sales processes, specifically in order to manage "new" forest owners and the demand of forest industries. The results highlight the domination of service logics associated with timber production and the challenges for the service market and the provision of diversified services to forest owners.

    In the eye of the storm: adaptation logics of forest owners in management and planning in Swedish areas2018In: Scandinavian Journal of Forest Research, ISSN 0282-7581, E-ISSN 1651-1891, Vol. 33, no 8, p. 800-808Article in journal (Refereed)
    Abstract [en]

    With a changing climate, storm and wind throw is becoming an increasing risk to forest. However, Swedish forest management practices have so far involved relatively little consideration of adaptation to climate change. This study examined resistance and alternatives to business as usual forest management, drawing upon material obtained in interviews with individual forest owners who spontaneously identified and discussed storm and wind throw as a risk to their forest. They thereby expressed a logic differing from that of the forest industry in Sweden, which has largely normalised storm risk rather than considering it in climate change adaptation work. The present analysis illustrates the broad and largely concerned position of individual forest owners, in contrast with a more established industry position on storm as an accepted and existing risk. Overall, the study highlights the diversity, agency and power relations within Swedish forestry and the forested landscape - aspects that are vital to better understanding processes relevant to forest and climate change adaptation.

    Adaptation to climate change in forestry: a perspective on forest ownership and adaptation responses2017In: Forests, ISSN 1999-4907, E-ISSN 1999-4907, Vol. 8, no 12, article id 493Article in journal (Refereed)
    Abstract [en]

    Adaptation to climate change has often been discussed from the perspectives of social vulnerability and community vulnerability, recognising that characteristics at local level will influence the particular adaptations undertaken. However, the extent to which national-level systemic factors influence and shape measures defined as adaptations has seldom been recognised. Focusing on adaptation to climate change in forestry, this study uses the example of two countries in the northern hemisphere with different forest ownership structures, forestry industry and traditions: Sweden, with strong private, non-industrial ownership, dominant forest industry and long forestry traditions; and Scotland, with forest ownership dominated by large estates and investment forestry based on plantations of exotic conifer species. The study shows how adaptation to climate change is structurally embedded and conditioned, which has resulted in specific challenges and constraints for different groups of forest owners within these two different contexts. This produces a specific set of political spaces and policy tools by rendering climate change in relation to forestry manageable, negotiable and practical/logical in specific ways. It is recommended that the focus of future work on climate-related issues and development of adaptation measures and policy should not be primarily on climate-related factors, but on institutional analysis of structural factors and logics in target sectors, in order to critically explore concepts of agency and power within these processes.

    "Jag ville ge mitt barn de bästa förutsättningarna": En kvalitativ intervjustudie om tankar kring matvanor under graviditet hos nyblivna förstagångsmammor2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Bakgrund Den blivande mammans matvanor under graviditeten är viktiga eftersom hon har ett ökat näringsbehov och försörjer en annan individ. En del av grunden för barnets framtida hälsa och matvanor ges redan i mammans mage. Trots det har studier visat att mammans matintag är otillräckligt jämfört med rekommendationerna samt att intaget av godis och fikabröd ofta ökar under graviditeten.

    Syfte Syftet med studien var att utforska inställningen till hälsosam och ohälsosam mat, samt hur denna inställning upplevdes påverka matintaget, hos nyblivna förstagångsmammor under graviditeten.

    Metod Åtta intervjuer genomfördes med nyblivna förstagångsmammor. Intervjuerna genomfördes med en semistrukturerad intervjuguide och spelades in med hjälp av en inspelningsapp. Data som samlades in transkriberades och analyserades sedan med kvalitativ innehållsanalys.

    Resultat Deltagarna berättade att de ändrade inställningen till sina matvanor då de blev gravida. Det blev allt viktigare att äta en varierad kost innehållande mycket grönsaker och frukt (hälsosam mat), och intaget av snabbmat och produkter innehållande mycket socker minskade (ohälsosam mat). Denna inställning följdes inte under hela graviditeten, och intaget av snabbmat och sockerrika livsmedel ökade under den senare delen. Kostråden från vårdpersonal upplevdes som bristfälliga på grund av att de gavs för få råd, och att mycket information själv fick hämtas från framförallt Livsmedelsverket.

    Slutsats Deltagarna följde inte sin initiala inställning till upplevd hälsosam och ohälsosam mat under hela graviditeten. Deltagarna efterfrågade även mer information om mat under graviditet från vårdpersonal. Mer stöd och information från vården kan ge den gravida kvinnan bättre förutsättningar till att hålla en hälsosam kost under hela graviditeten.

    Treåringars matvanor, fysiska aktivitet, samt Body Mass Index i Västerbotten: I relation till amningsduration och familjekonstellation2014Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Bakgrund Forskning har visat att hur länge barn ammats, har betydelse för deras hälsa senare i livet. Även barnens sociala miljö har visat sig ha effekt på hälsan och barnens matvanor. Salut är en satsning av Västerbottens läns landsting med målet att förbättra länsbornas hälsa fram till 2030.

    Syfte Syftet med studien var att undersöka treåringars matvanor, Body Mass Index (BMI) och fysiska aktivitet i relation till amningsduration och familjekonstellation.

    Metod Studien genomfördes genom ett samarbete med Salut som utformade och delade ut en enkät via barnavårdscentraler till samtliga föräldrar vid treårskontrollen. Enkäten innehöll frågor om barnens fysiska och psykiska hälsa, samt livsstil och levnadsvanor och totalt beabetades 210 av enkäterna i denna studie, där 16 frågor valdes ut. Dessa analyserades sedan statistiskt i IBM SPSS 21.0 Statistics. Signifikansnivån sattes till p<0,05.

    Resultat De flesta av barnen åt enligt rekommendationerna för livsmedelsintag, med undantag för rekommendationerna om fisk samt sötsaker. De flesta barnen nådde även upp till rekommendationerna om fysisk aktivitet. De flesta mödrar ammade inte sina barn efter rekommendationerna. Det utlästes en signifikant skillnad mellan hur länge barnen ammats totalt och hur ofta de åt sötsaker som visade att barn som ammats under sex månader hade ett högre intag än de som ammats längre. (p=0,033)

    Slutsats Barnen åt enligt rekommendationerna för de flesta livsmedel, utom fisk, som barnen åt mer sällan än vad som rekommenderas, samt sötsaker, som intogs oftare. Den information som framkommit i denna studie kan förtydliga vikten av att börja ett hälsofrämjande arbete i tidig ålder för att grundlägga goda vanor som sedan följer med barnen genom livet.

    Wood-Inhabiting Beetles in Low Stumps, High Stumps and Logs on Boreal Clear-Cuts: Implications for Dead Wood Management2015In: PLoS ONE, ISSN 1932-6203, E-ISSN 1932-6203, Vol. 10, no 3, article id e0118896Article in journal (Refereed)
    Abstract [en]

    The increasing demand for biofuels from logging residues require serious attention on the importance of dead wood substrates on clear-cuts for the many forestry-intolerant saproxylic (wood-inhabiting) species. In particular, the emerging harvest of low stumps motivates further study of these substrates. On ten clear-cuts we compared the species richness, abundance and species composition of saproxylic beetles hatching from four to nine year old low stumps, high stumps and logs of Norway spruce. By using emergence traps we collected a total of 2,670 saproxylic beetles among 195 species during the summers of 2006, 2007 and 2009. We found that the species assemblages differed significantly between high stumps and logs all three years. The species assemblages of low stumps, on the other hand, were intermediate to those found in logs and high stumps. There were also significant difference in species richness between the three examined years, and we found significant effect of substrate type on richness of predators and fungivores. As shown in previous studies of low stumps on clear-cuts they can sustain large numbers of different saproxylic beetles, including red-listed species. Our study does, in addition to this fact, highlight a possible problem in creating just one type of substrate as a tool for conservation in forestry. Species assemblages in high stumps did not differ significantly from those found in low stumps. Instead logs, which constitute a scarcer substrate type on clear-cuts, provided habitat for a more distinct assemblage of saproxylic species than high stumps. It can therefore be questioned whether high stumps are an optimal tool for nature conservation in clear-cutting forestry. Our results also indicate that low stumps constitute an equally important substrate as high stumps and logs, and we therefore suggest that stump harvesting is done after carefully evaluating measures to provide habitat for saproxylic organisms.

    Genetic status of Norway spruce (Picea abies) breeding populations for northern Sweden2013In: Silvae Genetica, ISSN 0037-5349, Vol. 62, no 3, p. 127-136Article in journal (Refereed)
    Abstract [en]

    Efficient use of any breeding resources requires a good understanding of the genetic value of the founder breeding materials for predicting the gain and diversity in future generations. This study evaluates the distribution of genetic variation and level of relatedness among and within nine breeding populations of Norway spruce for Northern Sweden using nuclear microsatellite markers. A sample set of 456 individuals selected from 140 stands were genotyped with, 15 SSR loci. Over all loci each individual was identified with unique multilocus genotype. High genetic diversity (average H-e=0.820) and low population differentiation (F-ST = 0.0087) characterized this material. Although low in F-ST, the two northernmost populations were clustered as a distinct group diverged from the central populations. The population differentiation pattern corresponds well with the post glacial migration history of Norway spruce and the current gene flow and human activity in the region. The average inbreeding coefficient was 0.084 after removal loci with high frequency of null alleles. The estimated relatedness of the trees gathered in the breeding populations was very low (average kinship coefficient 0.0077) and not structured. The high genetic variation and low and not structured relatedness between individuals found in the breeding populations confirm that the Norway spruce breeding stock for northern Sweden represent valuable genetic resources for both long-term breeding and conservation programs.

    Treating birch wood with a switchable 1,8-diazabicyclo-[5.4.0]-undec-7-ene-glycerol carbonate ionic liquid2012In: Holzforschung, ISSN 0018-3830, E-ISSN 1437-434X, Vol. 66, no 7, p. 809-815Article in journal (Refereed)
    Abstract [en]

    The suitability of a new switchable ionic liquid (SIL) has been investigated as a solvent for fractionation of lignocellulosic materials. SIL was prepared from inexpensive chemicals, e. g., glycerol, CO2, and 1,8-diazabicyclo-[5.4.0]-undec-7-ene (DBU). Fresh Nordic birch wood (B. pendula) was treated with the SIL for a time period of 1-5 days at 100 degrees C and under atmospheric pressure. Upon SIL treatment, at best, 57 % of the hemicelluloses were dissolved and 50 % of lignins were dissolved from the native birch. The slightly fibrillated SIL treated chips contained about 55 % cellulose. Up to 76 % of the recovered species removed from the spent SIL liquor was originating from hemicelluloses, mainly from xylan. The spent SILs were reused for fresh wood dissolution in four consecutive cycles and each time the wood dissolution efficiency was similar. SILs could offer affordable (easy-to-synthesize) solvent systems for partial elimination of hemicelluloses and lignin from wood. SILs can also be prepared in-situ and on-site.

    Energi- och näringsintag hos elitinnebandyspelare på idrottsgymnasium.2018Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [sv]

    Bakgrund En del unga idrottstalanger väljer att kombinera sina studier med en specialidrott på idrottsgymnasier, vilket kan innebära avflyttning från familjen och förändrat kostintag. Kosthållningen påverkar i sin tur idrottarens prestationsförmåga, risk för skador, sjukdomar samt tillväxt för yngre idrottare.

    Syfte Att undersöka energi- och näringsintag i relation till uppskattat energibehov och näringsrekommendationer hos elitinnebandyspelare på idrottsgymnasium.

    Metod En kvantitativ studie gjordes utifrån fyra dagars vägd kostregistrering genomförd av 18 deltagare och 12 av dessa utförde samtidigt en aktivitetsregistrering. Energi – och makronutrienter jämfördes med rekommendationer för gruppen enligt Nordiska näringsrekommendationer och Svenska olympiska kommittén. Mikronutrienterna kalcium, vitamin D och järn jämfördes med uppskattat genomsnittsbehov (AR) och analyserades med icke parametriska test.

    Resultat Sett till energiprocent låg majoriteten av deltagarna inom eller över rekommendationen för makronutrienter. Detsamma gällande proteinintaget uttryckt i g/kg kroppsvikt. Majoriteten av deltagarna kom ej upp i rekommenderad mängd kolhydrater uttryckt i g/kg kroppsvikt. AR för kalcium tillgodosågs av samtliga deltagare. AR för järn täcktes i större utsträckning av män. Samtliga deltagare hade utifrån kost- och aktivitetsregistreringen ett rapporterat energiintag som låg under uppskattat energibehov.

    Slutsats Resultatet indikerar att deltagarna inte hade att adekvat intag av kolhydrater, järn och vitamin D i jämförelse med rekommendationer. Rapporterat energiintag tyder på dock på underrapportering av energiintag, vilket gör att intaget av makro- och mikronutrienter bör tolkas med försiktighet. Underrapportering och ett lågt antal deltagare har gjort det svårt att dra slutsatser utifrån denna studie. Ytterligare studier bör utföras för att se hur unga idrottares energi- och näringsintag kan optimeras.

    Hur upplevs och hanteras familjens vardag av mödrar till barn med celiaki?: en kvalitativ intervjustudie2016Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    ABSTRACT                         

    Background: Celiac disease (CD) is an autoimmune disorder with a prevalence of 2/100 in Sweden. The only treatment is a diet free from gluten. Gluten occurs in grains of wheat, rye, barley and being diagnosed with CD often means that a change in eating habits is necessary. Living together with someone with CD has been shown to be problematic. Family life may be negatively affected and parents of children with CD experience worry and anxiety for their child.

    Objective: The aim of the study was to examine how mothers of children with CD experienced and handled everyday life in relation to their child's gluten-free diet (GFD).

    Method: A targeted selection was used and qualitative, semi-structured interviews were conducted with nine mothers of children with CD. The interviews were recorded and transcribed verbatim and then analyzed with qualitative content analysis.

    Results: All participants felt that everyday life had been adapted to the child with CD and there were different ways to deal with the GFD. Some chose to have the home as a gluten-free zone to avoid the stress of risking to give the child wrong food. Others chose to have both gluten-containing and gluten-free foods at home because of economic aspects and preferences from other family members. The level of knowledge about CD in the community was considered low, which was perceived to complicate everyday life for mothers of a child with CD. The majority of participants expressed that best support was found through Internet and social media.

    Conclusion: According to mothers of children with CD, the disease involved some dilemmas and daily life was at times perceived as worrisome, which can affect quality of life. Internet and social media were considered as good support in everyday life. Increased knowledge in society and greater understanding from the environment could improve families everyday life.

    Information om viktminskning på internet: En intervjustudie med fokus på tillförlitlighet, ideal och viktminskningsmetoder2011Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Bakgrund Dagens samhälle är präglat av en medvetenhet kring övervikt, vilket kan ha lett till de ideal som råder när det gäller kropp och hälsa. Media påverkar samhällets ideal kring utseende och har en viktig roll vid spridning av kostinformation gällande viktnedgång.

    Syfte Syftet är att utforska synen på webbpublicerad kostinformation gällande viktnedgång.

    Metod Fyra kvalitativa intervjuer genomfördes och urvalet baserades på att deltagarna skulle ha en vilja att minska i vikt samt regelbundet läste kostinformation gällande viktnedgång på internet.

    Resultat Deltagarna trodde inte att informationen som ges i kvällstidningarnas webbupplaga är tillförlitlig och att enda syftet är att tjäna pengar. Man upplevde förvirring kring nya rön och metoder gällande viktminskning och ansåg att omgivningen lätt tar till sig den information som finns på internet. Idealen i samhället och som visas på internet ansågs vara förvridna och ohälsosamma. Idealet tycktes vara en smal och vältränad kropp vilket informanterna inte själva upplevde sig kunde nå upp till och kände ett misslyckande över och gjorde att de även kände sig än mer uppgivna inför en viktminskning. Man menade också att begrepp som hälsa och sundhet förvridits till att mest handla om smalhet och att forma kroppen. Vidare uppfattade informanterna att de så kallade fettdieterna florerar mycket på webben och kändes svåra att särskilja. Samtidigt lockade snabba metoder i allmänhet och man betraktade snabba reslutat som önskvärt.

    Slutsats Denna studie har indikerat att idealen som upplevs råda i samhället vad gäller utseende kan leda till obehagskänslor hos de som inte kan nå upp till dem. Vad som är tillförlitligt är inte helt självklart och en viss förvirring uppfattas råda bland människor vad gäller råd om viktnedgång.

    Native Oxy-PAHs, N-PACs, and PAHs in historically contaminated soils from Sweden, Belgium, and France: their soil-porewater partitioning behavior, bioaccumulation in Enchytraeus crypticus, and bioavailability2014In: Environmental Science and Technology, ISSN 0013-936X, E-ISSN 1520-5851, Vol. 48, no 19, p. 11187-11195Article in journal (Refereed)
    Abstract [en]

    Soil quality standards are based on partitioning and toxicity data for laboratory-spiked reference soils, instead of real world, historically contaminated soils, which would be more representative. Here 21 diverse historically contaminated soils from Sweden, Belgium, and France were obtained, and the soil-porewater partitioning along with the bioaccumulation in exposed worms (Enchytraeus crypticus) of native polycyclic aromatic compounds (PACs) were quantified. The native PACs investigated were polycyclic aromatic hydrocarbons (PAHs) and, for the first time to be included in such a study, oxygenated-PAHs (oxy-PAHs) and nitrogen containing heterocyclic PACs (N-PACs). The passive sampler polyoxymethylene (POM) was used to measure the equilibrium freely dissolved porewater concentration, C-pw, of all PACs. The obtained organic carbon normalized partitioning coefficients, K-TOC, show that sorption of these native PACs is much stronger than observed in laboratory-spiked soils (typically by factors 10 to 100), which has been reported previously for PAHs but here for the first time for oxy-PAHs and N-PACs. A recently developed K-TOC model for historically contaminated sediments predicted the 597 unique, native K-TOC values in this study within a factor 30 for 100% of the data and a factor 3 for 58% of the data, without calibration. This model assumes that TOC in pyrogenic-impacted areas sorbs similarly to coal tar, rather than octanol as typically assumed. Black carbon (BC) inclusive partitioning models exhibited substantially poorer performance. Regarding bioaccumulation, C-pw combined with liposome-water partition coefficients corresponded better with measured worm lipid concentrations, C-lipid (within a factor 10 for 85% of all PACs and soils), than C-pw combined with octanol-water partition coefficients (within a factor 10 for 76% of all PACs and soils). E. crypticus mortality and reproducibility were also quantified. No enhanced mortality was observed in the 21 historically contaminated soils despite expectations from PAH spiked reference soils. Worm reproducibility weakly correlated to C-lipid of PACs, though the contributing influence of metal concentrations and soil texture could not be taken into account. The good agreement of POM-derived C-pw with independent soil and lipid partitioning models further supports that soil risk assessments would improve by accounting for bioavailability. Strategies for including bioavailability in soil risk assessment are presented.

    Dyra kalorier i frukt och grönsaker: En studie om prisutveckling och kostnader för livsmedel i relation till energitäthet2011Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Bakgrund Livsmedel med låg energitäthet är förknippat med bättre hälsa och lägre risk att drabbas av fetma. Studier visar att livsmedel med låg energitäthet inte bara är dyrare per kilokalori utan också har ökat mer i pris än energitäta livsmedel. Därför var det intressant att undersöka om priset och prisutvecklingen på livsmedel i Sverige skiljer sig åt beroende på energitäthet.

    Syfte Syftet med studien var att undersöka huruvida det fanns ett samband mellan energitäthet och prisutveckling för livsmedel under åren 1991-2010. Vidare var syftet att undersöka ifall priset för livsmedel skiljer sig åt beroende på energitäthet.

    Metod Utifrån en kostfrekvensenkät från Västerbottens hälsoundersökning och statistiska centralbyråns prisdatalistor valdes 122 livsmedel ut. Energitäthet räknades ut och livsmedlen räknades om till pris per ätlig del och pris per kilokalori. Prisförändringar och energikostnader för livsmedel indelade i sextiler utifrån energitäthet och procentuell prisförändring analyserades med hjälp av statistiska tester.

    Resultat De livsmedel som hade ökat mest i pris mellan 1991 och 2005/2010 samt 2005 och 2010 hade ingen signifikant lägre energitäthet än de livsmedel som ökat minst. Skillnaden mellan livsmedel med låg energitäthet och energitäta livsmedel gällande pris per 1000 kilokalorier var betydande. För den gruppen med lägst energiinnehåll var det genomsnittliga priset 91,3 kr och för energitätaste gruppen var genomsnittspriset på 14,5 kr (p<0,001).

    Slutsats Det fanns inget samband mellan energitäthet och prisförändringar mellan åren 1991, 2005 och 2010. Livsmedel med låg energitäthet var dyrare per kilokalori. Detta kan vara en orsak till att personer med begränsad ekonomi väljer att köpa billigare energitäta livsmedel. Att införa en skatt på ohälsosamma livsmedel skulle vara ett alternativ för att få personer att äta mer hälsosamt.

    En vegetariska dag i veckan: En studie som utvärderar gymnasieelevers inställning till och efterfrågan av vegetarisk skollunch, samt deras upplevda delaktighet kring skollunchen i en skola i Umeå kommun.2014Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Background Meat consumption increased in Sweden between the years 2000-2010 with 20 % per capita. Meanwhile, there are recommendations from the Swedish National Food Agency to reduce intake from charcuteries and red meat, as well as to increase intake of vegetables and pulses.

    Objective The purpose of this study was to evaluate Umeå municipality’s project: “A vegetarian day once a week”, through assessing upper secondary school pupil’s attitudes to and perceived demand of vegetarian school lunch as well as their participation at mealtimes at a school in Umeå.

    Method A questionnaire was designed in the program esMakerNX2. The questionnaire was distributed through mail and as a paper-based version in an upper secondary school in the municipality of Umeå, during the spring of 2014. Convenience sampling was used. Data collected were analyzed in IBM SPSS Statistics 21 with a significance level of p<0,05.

    Results A total of 122 pupils participated, 68 girls and 54 boys. About half of the participants, 51 % (n=62), ate every time when only the vegetarian meal alternative was offered. Girls chose the vegetarian meal alternative more often than boys (p<0,001). Almost half of the pupils, 48 % (n=28), chose the vegetarian meal primarily because of the good taste. Results even showed that 14 % (n=17) ate vegetarian meals more often since the start of the project, whilst 9 % (n=10) ate less often.

    Conclusion The pupils had different opinions about vegetarian meals in school. Almost half of the pupils chose not to eat when the lunch served was exclusively vegetarian. The interest of vegetarian food was stronger among girls than boys. A few upper secondary school pupils were influenced by the project to eat more vegetarian food, which shows that changing people ́s meal patterns is a big task where more knowledge and work is needed.

    Abstract [en]

    Background The prevalence of both coeliac disease and diabetes type I in the pediatric population varies between 2.4-16.4 %. Both diseases demand a strictly controlled diet A limited number of studies are investigating the practical implementation of the two diets. Objective To investigate parent’s experiences of the diet, when having a child with both coeliac disease and diabetes type I. Method A qualitative method was used in form of narratives, collected through a web based form. The informants consisted of 26 parents, having a child of age 3-16 years, diagnosed with both coeliac disease and diabetes type I. Qualitative content analysis was used to analyze the narratives. Result Difficulties were experienced by the informants considering the practical implementation of the two diets. The double diagnosis demanded frequent planning. Lack of knowledge in the surroundings was experienced, for example in staff at school and restaurants. The possibilities of saving time and money were limited and there were limitations also in the food supply, especially gluten-free products with low glycemic index. Due to experience of inconvenience and negative treatment from their surroundings, the feelings of being different were enhanced. Conclusion Difficulties in trusting others knowledge regarding the diet lead to compliance issues and put restraint to the children’s social life. Perceptions of lack of treatment and understanding in the surroundings could enhance the feeling of not being like everyone else and being a nuisance. A need for education aimed at staff in schools and restaurants exists to increase knowledge and understanding. More materials regarding cooking with the double-diagnosis are desirable. Constant planning lead to limitations in the daily life and the parenting role became more controlling, which could create difficulties when guiding the child into independence. Also the supply of gluten-free products with low glycemic index is limited and need further development.

    Vegankost eller blandkost?: En jämförelse av näringsintag, livsmedelsval och måltidsmönster hos förskolebarn som äter vegankost och blandkost.2012Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Background: The discussions and studies on vegan diet for children are many and with diverged opinions and results. The negative views, where the risks of deficiencies in the diet is in focus often dominates. Many studies show that if the most common pitfalls are avoided the growth of vegan children is normal. Today, the debate often focus on the risks of giving children a vegan diet, while the unbalanced mixed diet is easily forgotten. The latest national study of children´s dietary habits in Sweden (2003), reported a satisfactory distribution of protein, fat and carbohydrates, while the type of fat and carbohydrates consumed were of bad quality.

    Objective: The aim of this study was to investigate the nutritional intake, food choice and meal patterns among vegan and omnivore preschool children. The study also investigated whether the nutrient intake was consistent with the recommendations by the National Food Agency (NFA).

    Method: A quantitative method was used where a three-day estimated dietary registration of twelve children was performed, where half of the children were vegans and the other half omnivores. 

    Results: Children who ate a vegan diet consumed more fruit and vegetables, fibers and had a higher energy intake. The difference on the intake of fruit and vegetables was not significantly. The omnivores had a higher intake of sugar, salt and saturated fat, with a significant difference for the latter two. The vegan children had consistently a higher mean value of all nutrients with the exception of selenium and B12. The difference was only significant for the intake of vitamin C. Both groups had a satisfactory meal patterns.

    Conclusion: The vegan children had an intake more in accordance with the NFA recommendations than the omnivore children, indicating highly motivated and knowledgeable parents of the children who ate a vegan diet.

    DNA methylome of the 20-gigabase Norway spruce genome2016In: Proceedings of the National Academy of Sciences of the United States of America, ISSN 0027-8424, E-ISSN 1091-6490, Vol. 113, no 50, p. E8106-E8113Article in journal (Refereed)
    Abstract [en]

    DNA methylation plays important roles in many biological processes, such as silencing of transposable elements, imprinting, and regulating gene expression. Many studies of DNA methylation have shown its essential roles in angiosperms (flowering plants). However, few studies have examined the roles and patterns of DNA methylation in gymnosperms. Here, we present genome-wide high coverage single-base resolution methylation maps of Norway spruce (Picea abies) from both needles and somatic embryogenesis culture cells via whole genome bisulfite sequencing. On average, DNA methylation levels of CG and CHG of Norway spruce were higher than most other plants studied. CHH methylation was found at a relatively low level; however, at least one copy of most of the RNA-directed DNA methylation pathway genes was found in Norway spruce, and CHH methylation was correlated with levels of siRNAs. In comparison with needles, somatic embryogenesis culture cells that are used for clonally propagating spruce trees showed lower levels of CG and CHG methylation but higher level of CHH methylation, suggesting that like in other species, these culture cells show abnormal methylation patterns.

    Whole grain intake in adolescents assessed by the web-based dietary assessment method Riksmaten flex – a validation study2016Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Background During the year 2016-2017 the Swedish national food agency will perform a national dietary survey focusing on adolescents. In the work with the survey a new web based dietary assessment method, Riksmaten flex was developed. The current study was a part of the pilot study prior to the main survey.

    Objective To validate the reported intake of whole grains from Riksmaten flex against 24-hour recalls and alkylresorcinols as a biomarker of whole grain intake from wheat and rye.

    Method A crossover study was performed on adolescents, from elementary schools grade five and eight together with high school second graders, from different regions of Sweden. A total of 78 participants conducted two days of both dietary assessment methods and left blood samples for non-fasting plasma alkyresorcinol homologues to be analyzed.

    Results The intake from whole grains and whole grains from wheat and rye was 3.0 respectively 1.0 in the 24-hour recalls and 3.5 respectively 1.1 in Riksmaten flex. Spearman’s correlation coefficient between non-fasting plasma total alkylresorcinols and whole grains from wheat and rye was 0.36 for Riksmaten flex. Furthermore single and multiple regression models showed significant associations between the energy adjusted intake of whole grains from wheat and rye (g/MJ) and total alkylresorcinols in Riksmaten flex (p<0.01).

    Conclusion A significant correlation was seen between the reported intake of whole grains from wheat and rye in Riksmaten flex and the 24-hour recalls. A significant correlation was furthermore seen between the intake of whole grains from wheat and rye in Riksmaten flex and non-fasting plasma alkylresorcinol homologue levels. The correlation between the methods was weak but the overall result from this study suggests that Riksmaten flex captures the whole grain intake from wheat and rye in a valid way and can be used to assess this intake in Swedish adolescents.

    Importance of tannins for responses of aspen to anthropogenic nitrogen enrichment2016Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    Boreal forests are often strongly nitrogen (N) limited. However, human activities are leading to increased N inputs into these ecosystems, through atmospheric N deposition and forest fertilization. N input into boreal forests can promote net primary productivity, increase herbivore and pathogen damage, and shift plant species composition and community structure. Genetic diversity has been suggested as a key mechanism to promote a plant species’ stability within communities in response to environmental change. Within any plant population, specific traits (e.g. growth and defense traits) can vary substantially among individuals, and a greater variation in traits may increase chances for the persistence of at least some individuals of a population, when environmental conditions change. One aspect of plant chemistry that can greatly vary among different genotypes (GTs) are condensed tannin (CTs). These secondary metabolites have been suggested to affect plant performance in many ways, e.g. through influencing plant growth, the interactions of plants with herbivores and pathogens, and through affecting litter decomposition, and hence the return of nutrients to plants. To investigate how genotypic variation in foliar CT production may mediate the effects that anthropogenic N enrichment can have on plant performance and litter decomposition, I performed a series of experiments. For these experiments, aspen (Populus tremula) GTs with contrasting abilities to produce foliar CTs (i.e. low- vs. high-tannin producers) were grown under 3 N conditions, representing ambient N (+0 kg ha-1), upper level atmospheric N deposition (+15 kg ha-1), and forest fertilization rates (+150 kg ha-1). This general experimental set-up was once established in a field-like environment, from which natural enemies were excluded, and once in a field, in which enemies were present. In my first two studies, I investigated tissue chemistry and plant performance in both environments. I observed that foliar CT levels decreased in response to N in the enemy‑free environment (study I), but increased with added N when enemies were present (study II). These opposing responses to N may be explained by differences in soil N availability in the two environments, or by induction of CTs after enemy attack. Enemy damage generally increased in response to N, and was higher in low-tannin than in high-tannin plants across all N levels. Plant growth of high‑tannin plants was restricted under ambient and low N conditions, probably due to a trade-off between growth and defense. This growth constraint for high‑tannin plants was weakened, when high amounts of N were added (study I and II), and when enemy levels were sufficiently high, so that benefits gained through defense could outweigh the costs of defense production (study II). Despite those general responses of low- and high‑tannin producers to added N, I also observed a number of individual responses of GTs to N addition, which in some case were not connected to the intrinsic ability of the GTs to produce foliar CTs. In study III, gene expression levels in young leaves and phenolic pools of the plants that were grown in the enemy‑free environment were studied. This study revealed that gene control over the regulation of the phenylpropanoid pathway (PPP) was distributed across the entire pathway. Moreover, PPP gene expression was higher in high-tannin GTs than in low‑tannin GTs, particularly under ambient N. At the low N level, gene expressions declined for both low- and high-tannin producers, whereas at the high N level expression at the beginning and the end of the PPP was upregulated and difference between tannin groups disappeared. Furthermore, this study showed that phenolic pools were frequently uncorrelated, and that phenolic pools were only to some extent related to tannin production and gene expression. In study IV, I investigated the decomposability of litter from the field plants. I found that N enrichment generally decreased mass loss, but there was substantial genetic variation in decomposition rates, and GTs were differentially responsive to added N. Study IV further showed that CTs only had a weak effect on decomposition, and other traits, such as specific leaf area and the lignin:N ratio, could better explain genotypic difference in mass loss. Furthermore, N addition caused a shift in which traits most strongly influenced decomposition rates. Collectively, the result of these studies highlight the importance of genetic diversity to promote the stability of species in environments that experience anthropogenic change.

    Defoliation of a grass is mediated by the positive effect of dung deposition, moss removal and enhanced soil nutrient contents: results from a reindeer grazing simulation experiment2019In: Oikos, ISSN 0030-1299, E-ISSN 1600-0706, Vol. 128, no 10, p. 1515-1524Article in journal (Refereed)
    Abstract [en]

    Herbivory is one of the key drivers shaping plant community dynamics. Herbivores can strongly influence plant productivity directly through defoliation and the return of nutrients in the form of dung and urine, but also indirectly by reducing the abundance of neighbouring plants and inducing changes in soil processes. However, the relative importance of these processes is poorly understood. We, therefore, established a common garden experiment to study plant responses to defoliation, dung addition, moss cover, and the soil legacy of reindeer grazing. We used an arctic tundra grazed by reindeer as our study system, and Festuca ovina, a common grazing-tolerant grass species as the model species. The soil legacy of reindeer grazing had the strongest effect on plants, and resulted in higher growth in soils originating from previously heavily-grazed sites. Defoliation also had a strong effect and reduced shoot and root growth and nutrient uptake. Plants did not fully compensate for the tissue lost due to defoliation, even when nutrient availability was high. In contrast, defoliation enhanced plant nitrogen concentrations. Dung addition increased plant production, nitrogen concentrations and nutrient uptake, although the effect was fairly small. Mosses also had a positive effect on aboveground plant production as long as the plants were not defoliated. The presence of a thick moss layer reduced plant growth following defoliation. This study demonstrates that grasses, even though they suffer from defoliation, can tolerate high densities of herbivores when all aspects of herbivores on ecosystems are taken into account. Our results further show that the positive effect of herbivores on plant growth via changes in soil properties is essential for plants to cope with a high grazing pressure. The strong effect of the soil legacy of reindeer grazing reveals that herbivores can have long-lasting effects on plant productivity and ecosystem functioning after grazing has ceased.

    Nitrogen dynamics of decomposing Scots pine needle litter depends on colonizing fungal species2019In: FEMS Microbiology Ecology, ISSN 0168-6496, E-ISSN 1574-6941, Vol. 95, no 6, article id fiz059Article in journal (Refereed)
    Abstract [en]

    In boreal ecosystems plant production is often limited by low availability of nitrogen. Nitrogen retention in below-ground organic pools plays an important role in restricting recirculation to plants and thereby hampers forest production. Saprotrophic fungi are commonly assigned to different decomposer strategies, but how these relate to nitrogen cycling remains to be understood. Decomposition of Scots pine needle litter was studied in axenic microcosms with the ligninolytic litter decomposing basidiomycete Gymnopus androsaceus or the stress tolerant ascomycete Chalara longipes. Changes in chemical composition were followed by C-13 CP/MAS NMR spectroscopy and nitrogen dynamics was assessed by the addition of a N-15 tracer. Decomposition by C. longipes resulted in nitrogen retention in non-hydrolysable organic matter, enriched in aromatic and alkylic compounds, whereas the ligninolytic G. androsaceus was able to access this pool, counteracting nitrogen retention. Our observations suggest that differences in decomposing strategies between fungal species play an important role in regulating nitrogen retention and release during litter decomposition, implying that fungal community composition may impact nitrogen cycling at the ecosystem level.

    The Swedish forestry model: more of everything?2017In: Forest Policy and Economics, ISSN 1389-9341, E-ISSN 1872-7050, Vol. 77, p. 44-55Article in journal (Refereed)
    Abstract [en]

    "The Swedish forestry model" refers to the forest regime that evolved following the 1993 revision of the Swedish Forestry Act. It is key to Swedish forest politics and used to capture the essence of a sustainable way of managing forests. However, the ideas, institutions and practices comprising the model have not been comprehensively analyzed previously. Addressing this knowledge gap, we use frame analysis and a Pathways approach to investigate the underlying governance model, focusing on the way policy problems are addressed, goals, implementation procedures, outcomes and the resulting pathways to sustainability. We suggest that the institutionally embedded response to pressing sustainability challenges and increasing demands is expansion, inclusion and integration: more of everything. The more-of-everything pathway is influenced by ideas of ecological modernization and the optimistic view that existing resources can be increased. Our findings suggest that in effect it prioritizes the economic dimension of sustainability. While broadening out policy formulation it closes down the range of alternative outputs, a shortcoming that hampers its capacity to respond to current sustainability challenges. Consequently, there is a need for a broad public debate regarding not only the role of forests in future society, but also the operationalization of sustainable development.

    Late stage pine litter decomposition: Relationship to litter N, Mn, and acid unhydrolyzable residue (AUR) concentrations and climatic factors2015In: Forest Ecology and Management, ISSN 0378-1127, E-ISSN 1872-7042, Vol. 358, p. 41-47Article in journal (Refereed)
    Abstract [en]

    The aim of this paper is to evaluate relationships between decomposition rates of Scots pine (Pinus sylvestris) and lodgepole pine (Pinus contorta var. contorta) needle litter in the late stage of decomposition (>30% accumulated mass loss), and the progressively changing concentrations of manganese (Mn), nitrogen (N), and acid unhydrolyzable residue (AUR), as well as mean annual temperature (MAT) and mean annual precipitation (MAP). Using available long-term decomposition studies on pine needle litter in a climate gradient in Sweden, we calculated annual mass loss and related to concentrations of Mn, N, and AUR at the start of each one-year period as well as to MAT and MAP. We investigated these relationships for (i) all data on annual mass loss combined and (ii) annual mass loss for five different decomposition categories as defined by accumulated mass loss. We found highly significant, negative, and dominant relationships between annual mass loss and N (R-2 = 0.39) and AUR (R-2 = 0.39), a slight but significant positive relationship to Mn (R-2 = 0.08) and a significant negative relationship to MAT (R-2 = 0.06). The relationships were dynamic, and changed with accumulated mass loss. The rate-dampening effect of N decreased to be a rate-enhancing effect at c. 60-80% accumulated mass loss. A similar trend was found for AUR, becoming rate-enhancing at 70-80% accumulated mass loss. For Scots pine needle litter the effect of MAT on mass loss decreased with increasing accumulated mass loss and changed to a rate-dampening effect at c. 50-70% accumulated mass loss. Mn showed a stimulating effect on mass loss rate in all categories whereas MAP showed no effect in this mainly boreal climatic gradient. The current approach indicates a method for detailed studies of rate-regulating factors for litter decomposition.

    Manganese in the litter fall-forest floor continuum of boreal and temperate pine and spruce forest ecosystems: A review2015In: Forest Ecology and Management, ISSN 0378-1127, E-ISSN 1872-7042, Vol. 358, p. 248-260Article, review/survey (Refereed)
    Abstract [en]

    We have reviewed the literature on the role of manganese (Mn) in the litter fall-to-humus subsystem. Available data gives a focus on North European coniferous forests. Manganese concentrations in pine (Pinus spp.) foliar litter are highly variable both spatially and temporally within the same litter species and for the genus Pinus we found a range from 0.03 to 3.7 mg g(-1). Concentrations were related negatively to site mean annual temperature (MAT) and annual actual evapotranspiration (AET) for pine species litter but not for that of Norway spruce (Picea abies) as a single species. Combined data for several species showed a highly significant relationship to MAT. Manganese peroxidase is an Mn-dependent enzyme, found in white-rot fungi, essential for the degradation of lignin and ligninlike compounds. The decomposition rates of lignified litter tissue (late phase) is positively related to the litter's Mn concentration. Further, the Mn concentration is positively related to the limit value for decomposition - the higher the Mn concentration the smaller the stable litter fraction. Manganese release from decomposing litter appears at least in part to be species related. Thus was release from pine needle litter significantly faster (p < 0.001) than that from the Mn-richer litter of Norway spruce. Over Northern Europe concentrations of total Mn in mor humus as well as extractable Mn in the mineral soil increase with decreasing MAT and over a climatic gradient the Mn concentrations in Norway spruce mor increase more with decreasing MAT than in a gradient with Scots pine. Higher Mn concentrations in humus appear to decrease its stability and result in a higher release of carbon dioxide (CO2) and dissolved organic carbon (DOC). We conclude that this may explain (i) the lower amount of carbon (C) in mor layers under Norway spruce as compared to Scots pine as well as the higher amount of C in mineral soil under spruce. The increase in nitrogen (N) concentration in humus, following N fertilization resulted in a decrease in that of Mn. We have found four cases - empirical - with negative interaction between Mn and N; (i) in pine foliar litter fall concentrations of Mn decrease with site MAT whereas those of N increase, (ii) in decomposing late-stage litter with N retarding and Mn stimulating decomposition, (iii) for the stable phase, limit values are related negatively to N and positively to Mn, and (iv) Mn concentrations in humus decrease with MAT whereas those of N increase.

    Abstract [en]

    Background Unhealthy eating habits are a contributing factor for poor health in Sweden. Food intervention programs at the workplace can improve employee’s health. Objective The aim of this study is to investigate the eating habits and the food situation among employees at different workplaces in Västerbottens läns landsting. Method Seventy-nine workplaces in Västerbottens läns landsting were asked to participate. After loss there were 207 participants from 18 different workplaces in the study. The data was processed and analyzed in SPSS 20.0 using chi-2-test and multiple response set, the level of significance was set to p<0,05. Results Thirty-five percent had needs for improvements of their eating habits while three percent had good eating habits, relation was seen with age. There were 30 % who didn’t eat fruit daily, connection with gender and age. There were 32 % who didn’t eat vegetables daily, connection with gender. The majority (54 %) ate fish/shellfish less than twice a week, association with occupation. There were 40 % who didn’t use liquid margarine for cooking, relation with income and age. Half (49 %) ate sausage at least once a week, relation with gender, age and accommodation. The majority (60 %) ate a snack daily, connection with gender, occupation, workplace, education, fruit- and vegetable intake. Offering of food at workplace varied between different workplaces and the experience of eating at work was both positive and negative. Improvements suggested were better canteen and better range of food served. Conclusion The result suggested that efforts need to be taken to improve healthy eating habits. Increase the intake of fruit, vegetables and fish/shellfish and the choice of fat in cooking/on bread need to improve. Food interventions at worksite can become an important channel to reach out with our message and improving the public health.

    Gymnasieelevers upplevda psykiska hälsa i relation till livsstilsfaktorer: En enkätstudie på gymnasieelever i Västernorrland2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    SAMMANFATTNING

    Bakgrund: Stress är en del av dagens psykiska ohälsa som kan påverka koncentrationsförmågan. Studier har visat ett samband mellan måltidsordning samt val av livsmedel och psykisk hälsa och att fysisk aktivitet kan påverka hälsan positivt.

     

    Syfte: Syftet var att undersöka gymnasieelevers upplevda psykiska hälsa med fokus på upplevd stress och koncentration, samt livsstilsfaktorer med fokus på konsumtion av sötade livsmedel, måltidsordning och fysisk aktivitet. Ytterligare ett syfte var att undersöka om det fanns något samband mellan upplevd psykisk hälsa och ovan nämnda livsstilsfaktorer samt eventuella skillnader mellan könen.

     

    Metod: En webbaserad enkät skickades till elever vid två gymnasieskolor i Västernorrland, under våren 2017. Enkäten besvarades av 212 deltagare och analyserades med Chi2-test, Fischers Exact test, Independent samples T-test och Mann-Whitney U test.

     

    Resultat: Majoriteten av gymnasieeleverna upplevde sin stressnivå som låg och att de oftast kunde koncentrera sig under lektionerna. Vidare var flertalet deltagare fysiskt aktiva och hade en god måltidsordning, däremot konsumerade 47 % sötade livsmedel flera gånger per vecka. Kvinnor upplevde sig vara mer stressade än män (p = <0,001) och en större andel av männen upplevde att de alltid eller oftast kunde koncentrera sig på lektionerna (p = 0,016). De gymnasieelever som hade en regelbunden måltidsordning upplevde sig mer stressade (p = 0,043) än övriga och de fysiskt aktiva upplevde sig oftare kunna koncentrera sig på lektionerna (p = 0,045).

    Slutsats: Majoriteten av gymnasieeleverna hade låg stressnivå, god koncentration, regelbunden måltidsordning och var fysiskt aktiva. Däremot så konsumerade många sötade livsmedel flera gånger i veckan. Det fanns även vissa könsskillnader och intressant vore att studera vad de kan bero på och om det går att göra något åt dem.

    Svenska dietister ställer diagnos: Nutritionsdiagnoser en del av nutritionsbehandlingsprocessen, en kvantitativ studie ur ett dietistperspektiv2015Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Background The Nutrition care process is a systematic, problem-solving approach with a standardized language used by dietitians for documentation. It stimulates dietitians to critically appraise and take evidence-based decisions on a patient's nutritional problems. The Swedish Association of Clinical Dietitians (DRF) appeals qualified dietitians to work according the NCP.

    Objective The aim was to study Swedish dietitians’ work with nutrition diagnosis according to the NCP.

    Method(s) A web-based questionnaire was developed. Dietitians was recruited through the social media Facebook and the DRF website. The collected data were processed in SPSS, analyzed by Chi-2-test and Correlate Bivariate Spearman, with significance level at p < 0.05.

    Results A total of 119 dietitians responded to the questionnaire and 103 (87 %) of the respondents wrote nutrition diagnosis. The respondents had on average worked with the NCP for 2 years (range 1-3 years), and over half worked in hospitals. There was a correlation between years working according to the NCP and the number of written diagnosis (r=-0.197, p=0.046). Also, the time for writing a nutritional diagnosis was reduced as the experience of working with NCP increased (r=-0.226, p=0.022). It was 60 % that thought their knowledge and experience in NCP could be improved, 89 % stated that the NCP was useful. The English in the reference sheets 48 % of the respondents said partly was difficult to understand and (n=13) wanted them to be translated into Swedish. It showed that more than half (53 %) of the dietitians sometimes composed PES-statements without finding the appropriate signs/symptoms in the reference sheet.

    Conclusion Swedish dietitians consider themselves to be in need of more knowledge and training in the NCP, and translations of the reference sheets would possibly increase the use of nutrition diagnosis. A further implementation of the NCP is needed in Sweden.

    Abstract [en]

    Background On a vegan diet it is important to make sure that one receives the nutrients that the body needs; for example vitamin B12, vitamin D, omega-3 fatty acids, iron, calcium, iodine and selenium. Few studies are made on food choices and food intake frequencies among people on a vegan diet.

    Objective To investigate food choices and intake frequencies of food and nutritional supplements among adults on a vegan diet in Sweden.

    Methods The objective was investigated by using a web based questionnaire. The web based questionnaire was published on the website Facebook. The criteria for inclusion were to be on a vegan diet, ≥18 years old and live in Sweden. Frequency tables, cross tables and Chi square test were used when analyzing data.

    Results The questionnaire was answered by 335 informants. Most of the informants chose organic foodstuffs. Pulses were eaten by 91 percent a few times a week or more often. Out of the participants 45 percent took vitamin D supplements a few times a week or more often. People who were ≥30 years were more likely to take omega-3 supplements compared to younger people (p<0.001). University-educated people took omega-3 supplements (p=0.034) and ate whole grain products (p=0.035) more frequently than the ones without university education. Informants who had lived on a vegan diet >3 years took omega-3 supplements more often than the ones who had lived on a vegan diet ≤3 years (p=0.002).

    Conclusion Many of the informants had a high intake frequency of nutritious foodstuffs, but some had a low intake frequency. An age >30 years, university education and being on a vegan diet for ≥3 years positively affected intake. Many informants took supplements of algae oil. It is important to make sure that proper dietary advice is given to people on a vegan diet.

    Tentative levels of pops in Lithuanian environment2005In: Environment, technology, resources: proceedings of the 5th International Scientific and Practical Conference on Environment, Technology and Resources, JUN 16-18, 2005 / [ed] Noviks, G, Rezekne: Rezekne higher education institution - Rezeknes Augstskola , 2005, p. 172-178Conference paper (Refereed)
    Abstract [en]

    Persistent Organic Pollutants (POPs) are chemical substances that persist in the environment, bioaccumulate through the food web, and pose a risk of causing adverse effects to human health and the environment. The Stockholm Convention is a global treaty to protect human health and the environment from POPs. In implementing the Convention, Governments will take measures to eliminate or reduce the release of POPs into the environment. This study was done in order to evaluate tentative POPs levels in Lithuania. Limited amount of PAHs and PCBs were analyzed in Siauliai air, in two biggest Lithuanian rivers - Nemunas and Neris, and in one of the biggest waste landfill in Lapes. Sampling was done using semipermeable membrane devices (SPMDs). The same procedure of sampling and analyses was used to ensure data comparability. In general, POPs pollution levels were compared with results from other studies.
