Abstract

Partially migratory populations in which some individuals move to allopatric ranges during one season while others remain on their shared range, offer a unique opportunity to understand which factors shape the realized niche of individuals with plastic movement behaviors. For ungulates, forage and its spatiotemporal variability, risk (predation, humans) and density have been suggested to be the main determinants for the probability, distance and timing of migration. Roe deer (Capreolus caproelus), a small browsing ungulate with a high ecological plasticity and a wide distribution, present an ideal model species to test hypotheses on migration plasticity.
