The authors demonstrate that a combination of habitat selection analysis at several trophic levels and at multiple spatial scales can provide an efficient quantitative framework for studying predator-prey spatial games in dynamical systems where both groups move constantly. Focussing on a caribou-moose-wolf food web, the study illustrates how differences in fine-scale movement tactics between predators and prey create asymmetry in their relative encounter probabilities.
