The costs and benefits of social foraging vary as a function of spatial position in the group in many species (Krause 1994; Romey 1997; Hirsch 2007). In particular, foraging opportunities and predation risk often differ for individuals at the edge relative to those at the center of the group. For instance, foraging success may be greater at the edge than at the more crowded center because resource depletion may occur faster at the center (Rowcliffe et al. 2004) or because individuals at the… CONTINUE READING
