Habitat selection by moose (Alces alces) in clear-cut landscapes.

摘要: Habitat selection by moose was studied over 4 years in two large sectors subject to intensive forest harvesting using a two-scale approach. At the coarser scale, i.e. location of home range within landscape, habitat did not appear be influenced presence clear-cuts. In one sector, preferred mature mixed stands, young coniferous, and coniferous stands. second highest preference noted for cut areas deciduous Moose ranges were located with higher edge interspersion among patches. Home size females positively related proportion cuts, but movements not. more pronounced at finer scale (animal locations range) differ between sectors. Mixed stands all seasons. Mature conifer summer early winter while late winter. Clear-cuts avoided except closer food cover than random locations, especially A marked decrease also This study shows differences pattern scales. For example, clear-cuts seem markedly influence adaptations minimize their impact seemed operate scale. Coarser probably linked trade-off predator avoidance browse availability, whereas seasonal changes suggest behavioural maximize energy gain counteract predation other adverse environmental conditions
