| Individual wildebeast treking across the Kenyan plains in the dry season on their way to an aggregation site as depicted in image DHJanzen100392.jpg above, for synchronous calving about the time that the rainy season begins. Note that selection for timing with a seasonal flush of food can also generate high synchrony of reproduction within a population (and between populations), and in this respect both food periodicity and predator satiation can operate to create a peak of activity (and determine WHEN on the calendar the peak occurs), though predator satiation phenomena are particularly good at trimming off the tails of the distribution around that peak. | ||
