As elephants compete for food, water, and mates, dominant groups and individuals will access higher-quality food resources and, in the case of males, a greater number of mates than those who are lower in rank. As elephants attempt to maximize their intake rate, they must make frequent decisions regarding when and where to go, with whom, and how long to stay in particular group configurations and specific locations. As predicted by optimal foraging theory, elephants must decide which groups and locations to gravitate toward or avoid so as to minimize within- and between-group competition and reduce encounters with (mainly human) predators. While foraging and mate-searching decisions by adult males are tailored to maximize individual fitness, those taken by females are likely also to be associated with increasing inclusive fitness, as is the case with many species living in kin-based social groups.
