With lower populations of Eurasian otter, zander, and perch, the brown bear population would be forced to prey upon more roe deer and moose, which would decrease the populations of those animals. Knowledge of the effect of habitat type and region on diet and feeding behaviours of a species facilitates a better understanding of factors impacting populations, which contributes to effective conservation management.
