Research overview: male coalitions and territoriality in cheetahs

Unusually for a solitary felid, male cheetahs often form lifelong coalitions, frequently of brothers, that cooperate to hold small, high-quality territories. This overview surveys research on coalition formation, the reproductive and survival advantages of grouping for males, and the contrast with the solitary ranging of females who move over much larger areas. It examines how coalitions defend territories against single males and rival groups and how territory holders gain mating access. The topic illuminates a distinctive social system that blends solitary and cooperative elements, and it shows how sex differences in ranging and grouping arise from the differing reproductive strategies of male and female cheetahs.
