Habitat-dependent foraging in a classic predator-prey system: A fable from snowshoe hares
Article Abstract:
A simple theory that integrates predation into evolutionary stable strategies of habitat selection, and the connection to foraging strategies in small patches are briefly reviewed. The conventional wisdom on snowshoe-hare habitat preference is reviewed to develop competing predictions on hare distribution and foraging.
