21. The influence of forestry stands treatments on brown bears (Ursus arctos) habitat selection in Sweden – an option for Alberta forestry?
University essay from SLU/Dept. of Wildlife, Fish and Environmental StudiesAbstract : The brown bear population in Alberta, Canada has been decreasing, while the Swedish has been increasing and all the affecting parameters are not known. This study examined the difference in these populations to see if an explanation could be found in differences between the forest management. READ MORE

22. Effects of brown bear (Ursus arctos) odour on the patch choice and behaviour of different ungulate species
University essay from SLU/Dept. of Wildlife, Fish and Environmental StudiesAbstract : The return of large predators to regions where they were previously extirpated has created a need for knowledge about their effect on prey species, not only their lethal but also their behavioural or risk effects. In this study the behavioural risk effects of brown bear (Ursus arctos) were tested on fallow deer (Dama dama), roe deer (Capreolus capreolus), red deer (Cervus elaphus), moose (Alces alces) and wild boar (Sus scrofa).

23. Brunbjörnens (Ursus arctos) inverkan på den nya svenska älgförvaltningen
University essay from SLU/Dept. of Forest Ecology and ManagementAbstract : The European Brown bear (Ursus arctos) has gone from basically being extinct in Sweden to, 2008 being estimated to a total of 3298 individuals. When looking at the new Swedish moose management system it is important to have an ecosystem-based approach and therefore include all the parts that moose impacts on and from in the management, especially the brown bear.

24. Transfer of radiocaesium (137Cs) to lynx (Lynx lynx) and brown bear (Ursus arctos) in Chernobyl affected areas in Sweden
University essay from SLU/Dept. of Soil and EnvironmentAbstract : In this study, 137Cs activity concentration was measured in 266 lynxes hunted in early spring during the years 2006-2011 in central and northern Sweden and in 161 bears hunted in the end of August until October during the years 2010 and 2011. Highest activity concentrations of 137Cs were observed in lynx and bear coming from counties with highest radiocaesium fallout after the Chernobyl accident. READ MORE

25. De novo sequencing and SNP discovery in the Scandinavian brown bear (Ursus arctos)
University essay from SLU/Dept. of Wildlife, Fish and Environmental StudiesAbstract : Development of molecular markers that are well-suited for use in studies on wildlife dispersal can greatly enhance conservation efforts of species affected by climate change and human-induced landscape alterations. Single nucleotide polymorphisms (SNPs) are a promising marker for such studies; however, development of SNPs in non-model species with limited or no sequence data can be challenging. READ MORE
