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 …

… numbers of roe deer started they have increased while the hunting numbers of red fox have declined. Red fox is the most frequent predator on roe deer on the island.
the importance of landscape structure and forage availability
Bark-stripping by red deer (Cervus elaphus) cause extensive damage to economically valuable spruce trees (Picea abies) in Swedish forests. The underlying causes for bark-stripping are not fully understood, and the frequency and severity of damage unpredictably differ between …

… techniques. During this study a total of 36 fawns (17 ”, 19 ”) were captured and marked with vhf or gps radio collars; 12 fawns in 2008 and 24 fawns in 2009. The neonate mortality calculated by the Kaplan-Meier method was 23.6 % and the mortality caused by predation was low …
… ways to decrease the damage on valuable and important trees. One example is to reduce the wild species population by hunting, another alternative is to increase the available forage for the game. Also, an increase in production of forage may lead to less damage by game and hence …
forage production, utilization by ungulates and browsing on adjacent forest
… and gamefields as potential methods for controlling the ungulate foraging and reducing browsing damage by providing other attractive food resources. However, quantitative estimates of potential biomass production of various gamefield crops and browsing pressure on the …
