Data for Drivers of disperser immigration into cooperatively breeding carnivore groups

Dispersal in group living animals requires not only movement but successful integration into established social groups, yet the ecological and social conditions that govern immigrant settlement remain poorly understood. Using 18 years of genetic life history data from cooperatively breeding gray wolves, ee investigated how group size, breeder turnover, genetic relatedness, and harvest intensity affected the probability of successful immigration by a disperser using a generalized linear model. We found that breeder turnover, particularly the loss of breeding males, and an interaction between group size and harvest strongly influence disperser settlement into groups.
