Beschreibung:
Partial seasonal migration is ubiquitous in many species. We documented this phenomenon in plains zebra ( Equus burchelli ) in Etosha National Park, Namibia (ENP), and provided a cost–benefit analysis as it relates to the spatial distribution of water, vegetation, and endemic anthrax. This analysis draws upon two years of ENP zebra movement data that reveal two sub-populations: migrators and non-migrators. Migrators are shown to be behaviorally dominant in the way they utilize space and use water holes. We raise the possibility that the co-existence of these two groups reflects an evolutionary process, and the size of each group maintains evolutionary equilibrium.
