Beaver foraging behaviour: Seasonal foraging specialization by a choosy generalist herbivore

Popis výsledku v původním jazyce

Classical theory states that generalist foragers should specialise to maximise their net energy intake on a temporal basis. Within broad distributions, generalists select optimal food sources; however, the availability and representation of selected food items in the diets of generalist consumers vary geographically. Conversely, specialists, within their entire range, concentrate on specific food resources, and their diets remain constant in varying environments. The distributions of highly palatable food resources might influence the foraging patterns of species with opportunistic foraging behaviours. We used the Eurasian beaver (Castor fiber) as a model for what is considered an opportunistic generalist herbivore. We analysed whether the beavers’ foraging pattern could show specialisation. Five beaver populations living in diverse environments were evaluated, and their diet choices for overwintering were examined. Our data indicated low proportions of generality with regard to the beavers’ foraging
