21. The return of the wolf : effects on prey, competitors and scavengers
Sammanfattning : Apex predators may have both direct and indirect effects on other species through predation and competition. I investigated the effects of wolves (Canis lupus) on prey species, competitors (including humans) and the scavenging guild after the re-colonization by wolves of the Scandinavian Peninsula. LÄS MER
22. Applying emerging genetic methods to wild model systems
Sammanfattning : Genetic material is an invaluable source of information for assessments of wild populations. By using information derived from genetic markers, individuals can be identified and tracked over time, enabling studies of a wide range of behavioral, ecological, and evolutionary processes. LÄS MER
23. Deciduous tree occurrence and large herbivore browsing in multiscale perspectives
Sammanfattning : Aspen ( Populus tremula), rowan (Sorbus auquparia) and sallow (Salix caprea) are deciduous tree species of low economic value for forestry and contribute to biodiversity of boreal forests. The species are rare in managed forest landscapes, and severely browsed by moose. LÄS MER
24. Increased resilience in managed boreal forests : Controlling damage by spruce bark beetle and moose in Sweden
Sammanfattning : Most of the forests growing in Europe today have been planted, or heavily affected, by humans. This is because the forest industry provides crucial raw materials for diverse products, including timber, pulp and paper, cellulose-based substances and renewable energy sources. LÄS MER
25. Adaptations of mobile ungulates in a changing North
Sammanfattning : The combined effects of global warming and land use changes experienced by animals at high latitudes, are poorly understood. Social and eco-physiological perspectives are therefore necessary to elucidate where and when animals and the ecosystems they represent are most vulnerable to environmental change. LÄS MER
