Spatially segregated foraging patterns of moose ( Alcesalces) and mountain hare ( Lepustimidus) in a subarctic landscape: different tables in the same restaurant?
Differences in body sizes of mountain hares (Lepus timidus L., 1758) and moose (Alces alces (L., 1758)) affect their ability to perceive and respond to environmental heterogeneity and plant density. Therefore, we expect these species to show niche separation at different scales in the same environme...

Moose browsing was clustered at spatial intervals of 1000–1500 m, while hare browsing was clustered at intervals of less than 500 m. Willows (genus Salix L.) in the study area were heavily browsed by moose, while few observations of hare browsing on willow were made. Regarding both hare and moose, numbers of birch stems with new browsing per sample plot were positively correlated with the numbers of birch stems with old browsing, indicating that hare and moose preferred the same foraging sites from year to year. These findings have implications for management of the species because they show the importance of scale and landscape perspectives in planning and actions.
