21. Apan som blev kock
Kandidat-uppsats, Lunds universitet/ArkeologiSammanfattning : How far back in time can we trace fire use in the human story? The archaeological data has demonstrated inconsistency when it comes to answering that question. Incontrovertible remains after hearths are scarce especially before 100,000 years BP. LÄS MER
22. Arctic Loess as an Environmental Archive : Identifying Weathering with XRF Analysis in West Greenland
Kandidat-uppsats, Uppsala universitet/Institutionen för geovetenskaperSammanfattning : Loess from west Greenland was studied to evaluate Holocene paleoclimate in the Arctic region. Deposits of loess are formed over long time scales through deposition of fine aeolian sediment and they exist in several places in the world. LÄS MER
23. Hantering av forn- och kulturlämningar inom SCA Norrbottens skogsförvaltning : informationshantering från planering till markberedning
Master-uppsats, SLU/Dept. of Forest Ecology and ManagementSammanfattning : Norra Sveriges skogar är rika på spår av människors levande och brukande som efterlämnat forn- och kulturlämningar som kan dateras ända tillbaka till forntiden då inlandsisen släppte sitt grepp om norra Skandinavien. Alla dessa forn- och kulturlämningar är skyddade mot all negativ åverkan och skador genom kulturmiljölagen och skogsvårdslagen. LÄS MER
24. PLANT MIGRATION AT THE END OF THE WEICHSELIAN GLACIATION : Macrofossil evidence of early coniferous trees at two northern Swedish sites
Master-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskapSammanfattning : Studies of vegetation history bring a new incentive to our understanding of plant survival and migration in arctic environments. For decades, environmental research was based on palynological data and these studies created a notion that tree species such as larch (Larix sibirica) and Scots pine (Pinus sylvestris) did not grow in northern Scandinavia at the end of Weichselian glaciation.

25. Aerosol Input and Snow Accumulation Rates on the Northern Greenland Ice Sheet : Reconstructed by means of Continuous Flow Analysis (CFA) of 6 shallow firn cores
Master-uppsats, Uppsala universitet/Institutionen för geovetenskaperSammanfattning : Ice, firn and snow cores from the Greenland ice sheet offer a unique opportunity to reconstruct past climate conditions. These can be analyzed with continuous flow analysis (CFA) in order to acquire proxy information about ancient atmospheric aerosol concentrations, snow accumulation rates or temperature variations, atmospheric composition, solar activity as well as volcanism and biological activity.
