Movement is among the most important adaptations of animals living in seasonal environments. Movement allows animals to exploit spatially and temporally variable resources; these resources in turn influence individual fitness and demographic rates of populations (Fryxell et al. 1988, Bolger et al. 2008, Mueller and Fagan 2008, Hebblewhite and Merrill 2009). A diverse movement portfolio, wherein a variety of movement behaviors are represented across space and time and among individuals in a population, likely is important for population persistence in the face of environmental change (Lowrey et al. 2020) and may be especially important for managers to re-establish in populations of endangered species.
