11. Restoration strategies in boreal forests : prescribed burning and gap cutting effects on plant diversity and community composition
University essay from SLU/Dept. of Wildlife, Fish and Environmental StudiesAbstract : The boreal biome is one of the largest in the world and their forests have been widely exploited for centuries. Consequently, it has suffered ecological simplification and loss of biodiversity. Under these circumstances passive conservation is no longer enough and active restoration techniques need to be tested. READ MORE

14. Fire effects in a landscape of fear : food availability and perceived predation risk as potential determinants of patch utilization by herbivore prey
University essay from SLU/Dept. of Wildlife, Fish and Environmental StudiesAbstract : 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.

15. Brandhårdhetens påverkan på knäckesjukans omfattning på brandfältet i Sala
University essay from SLU/Dept. of Forest Ecology and ManagementAbstract : Knäckesjuka (Melampsora pinitorqua) är en skoglig skadegörare som orsakar skador på ung tall (Pinus sylvestris). Svampen värdeväxlar mellan asp (Populus tremula) och tall för att fullborda sin livscykel. Tidigare studier visar en tydlig korrelation mellan hård brandhårdhet och kraftig lövetablering efter brand.
