16. The importance of Ecoparks for saproxylic beetles : a study on general ecological hypotheses in differently managed landscapes
Master-uppsats, SLU/Dept. of Wildlife, Fish and Environmental StudiesSammanfattning : Current forestry practices have led to a decline of deadwood availability in Swedish forests. Even though deadwood has increased somewhat in Swedish forests in later years, it is still far from estimated deadwood threshold levels and of those found in natural systems. This has in turn led to a decline in species associated with deadwood e.g. LÄS MER
17. Community structure of polyporous fungi after wildfire in boreal forest
Master-uppsats, SLU/Dept. of Wildlife, Fish and Environmental StudiesSammanfattning : Wildfire is a natural disturbance that creates large amounts dead wood and contribute to a landscape of different successional stages, important for biodiversity. The number of wildfires have declined in boreal Fennoscandia due to effective fire suppression. LÄS MER
18. Fire effects in a landscape of fear : food availability and perceived predation risk as potential determinants of patch utilization by herbivore prey
Master-uppsats, SLU/Dept. of Wildlife, Fish and Environmental StudiesSammanfattning : Context: A major effect of climatic change is the global increase in forest fires, which potentially creates an increase in food availability for herbivorous species. Also vegetation density and the numbers of tree logs increase in burned sites, and this is thought to influence the perceived risk of herbivore prey species, which affects their anti‐predator behaviour and thereby the patch utilization.

19. Regionala skillnader i nyckelbiotopers biodiversitet : med avseende på mängd död ved och artantal
Kandidat-uppsats, SLU/Dept. of Wildlife, Fish and Environmental StudiesSammanfattning : Den svenska skogen har genomgått en stor förändring de senaste århundradena av en markanvändning som startade tidigare och var mer intensiv i södra Sverige än i norra. De skogar som tidigare var naturliga och variationsrika är nu omvandlade till enskiktade produktionsskogar. LÄS MER
20. Vilket är det största hotet mot den afrikanska elefanten (Loxodonta spp.)?
Kandidat-uppsats, SLU/Dept. of Animal Environment and HealthSammanfattning : Den afrikanska elefanten är jordens största landlevande däggdjur. Det finns två olika varianter: afrikansk stäppelefant (Loxodonta africana) och afrikansk skogselefant (Loxodonta cyclotis). De afrikanska elefanterna är grundpelare i ekosystem genom att bland annat visa vägen till vatten och mat för både djur och människor. LÄS MER
