    Paleoentomology: Insects and other Arthropods in Environmental Archaeology2014In: The Encyclopedia of Global Archaeology / [ed] Claire Smith, Springer Science+Business Media B.V., 2014, p. 5740-5755Chapter in book (Refereed)
    Abstract [en]

    Insects are the most diverse group of animals on the planet, and as suchare present in a wider variety of habitats than most other organism groups.This diversity, in addition to a long evolutionary history (Grimaldi &Engel 2005), and together with a propensity to be preserved in both desiccatingand anaerobic environments, has provided an excellent tool for thereconstruction of both Quaternary and more immediate archaeologicalenvironments. Insect remains often provide proxy environmental information onthe immediate context from which the fossils are derived, and as such may beeither complementary to the more regional picture provided by palynology orindicate site conditions, such as levels of hygiene and evidence of tradingconnections, which are rarely available from any other palaeoecological source.They therefore provide information on a broad range of habitats and conditions,on- and off-site, and in addition, in appropriate contexts, also climate.Processing of samples is essentially simple, requiring readily availablematerials, yet is time consuming, and identification of the usuallydisarticulated fragments (sclerites) requires diligence and patience and accessto well curated reference collections. Fortunately, abundant literature,computer software and database tools now exist to aid in their interpretation.

    Makrofossilundersökning från en slutundersökning av SU Järnbrott, Västra Frölunda 192, Rio Projekt nr 1149.2012Report (Other academic)
    Abstract [sv]

    De tre prover (MAL nr. 12_0002:1-3) som erhölls för makrofossilanalys kommer från en arkeologisk slutundersökning av en förmodad grav, SU Järnbrott, Göteborgs kommun (N 57° 39' 51,75", E 11° 56' 2,01" (WGS84)).

    Flintmaterial från utgrävningsplatsen har sorterats och tolkningen blev att det har slagits flinta vid minst tre tillfällen. Bland annat består materialet av bifaciala avslag från senneolitikum. Då ben även har hittats kan det peka mot en grav.

    Syftet med makrofossilanalysen är att undersöka om det finns något som indikerar att det funnits en grav och/eller något annat på platsen.

    A continuous Holocene beetle record from the site Stavsåkra, southern Sweden: implications for the last 10 600 years of forest and land use history2008In: Journal of Quaternary Science, ISSN 0267-8179, E-ISSN 1099-1417, Vol. 24, no 6, p. 612-626Article in journal (Refereed)
    Abstract [en]

    Beetle remains from a small bog in southern Sweden contribute information concerning the forest history of the study area. The study shows that beetles are valuable indicators of woodland structures such as openness, field vegetation, presence of dead wood and disturbance factors such as climate change, fire regimes, grazing and land use. The early Holocene, ca. 8600–6450 cal. BC, was characterised by open, pine-dominated woodlands maintained by fire and grazing disturbances. The changes in the wetland fauna, between 8600 and 7500 cal. BC, correlate well with low lake levels in southern Sweden. During the mid Holocene, ca. 6450–2400 cal. BC, the woodlands were relatively dense, with few openings in the canopy. Around 4200 cal. BC, there was a shift to a dominance of deciduous trees. Fire and grazing pressures were particularly low. Numbers of aquatic and hygrophilic beetles indicate dry conditions between ca. 5000 and 3000 cal. BC. During the late Holocene, ca. 2400 cal. BC to present, the woodlands opened up mainly through increased land use. The main disturbance factors were fire and grazing. The beetles indicate the formation of heather-dominated heathland around 800 cal. BC.

    A case study of the role of climate, humans, and ecological setting in Holocene fire history of northwestern Europe2015In: Science China Earth Sciences, ISSN 1674-7313, Vol. 58, no 2, p. 195-210Article in journal (Refereed)
    Abstract [en]

    We present the major results from studies of fire history over the last 11000 years (Holocene) in southern Sweden, on the basis of palaeoecological analyses of peat sequences from three small peat bogs. The main objective is to emphasize the value of multiple, continuous sedimentary records of macroscopic charcoal (macro-C) for the reconstruction of local to regional past changes in fire regimes, the importance of multi-proxy studies, and the advantage of model-based estimates of plant cover from pollen data to assess the role of tree composition and human impact in fire history. The chronologies at the three study sites are based on a large number of C-14 dates from terrestrial plant remains and age-depth models are achieved using Bayesian statistics. Fire history is inferred from continuous records of macro-C and microscopic charcoal counts on pollen slides. The Landscape Reconstruction Algorithm (LRA) for pollen-based quantitative reconstruction of local vegetation cover is applied on the three pollen records for plant cover reconstruction over the entire Holocene. The results are as follows: (1) the long-term trends in fire regimes are similar between sites, i.e., frequent fires during the early Holocene until ca. 9 ka BP, low fire frequency during the mid-Holocene, and higher fire frequency from ca. 2.5 ka BP; (2) this broad trend agrees with the overall fire history of northwestern and western Europe north of the Mediterranean area, and is due to climate forcing in the early and mid-Holocene, and to anthropogenic land-use in the late Holocene; (3) the LRA estimates of plant cover at the three sites demonstrate that the relative abundance of pine played a primordial role in the early and mid-Holocene fire history; and (4) the between-site differences in the charcoal records and inferred fire history are due to local factors (i.e., relative abundance of pine, geomorphological setting, and anthropogenic land-use) and taphonomy of charcoal deposition in the small peat bogs. It is shown that continuous macro-C records are most useful to disentangle local from regional-subcontinental fire history, and climate-induced from human-induced fire regimes, and that pollen-based LRA estimates of local plant cover are more adequate than pollen percentages for the assessment of the role of plant composition on fire history.
