Abstract: Lay Summary Whether offspring remain or disperse from their area of birth affects opportunities to associate with parents and siblings. This has important implications for the development of family based social systems. An important part of understanding this process is therefore to understand the costs and benefits of dispersal for offspring. Using captive populations of a social lizard we show that the availability of suitable habitat influences the costs of dispersal and that these factors also influence the probability that offspring will delay dispersal and remain in close proximity to their mother.
