Decline and fall: The causes of group failure in cooperatively breeding meerkats

Abstract In many social vertebrates, variation in group persistence exerts an important effect on individual fitness and population demography. However, few studies have been able to investigate the failure of groups or the causes of the variation in their longevity. We use data from a long‐term stu...
