(With 8 Figures) (Acc. 2-VI) Introduction Sex-biased dispersal is a widespread phenomenon in birds and mam-mals. Oct 24,  · The former associates different patterns of sex‐biased dispersal with mating systems, such as female‐biased dispersal in monogamous birds and male‐biased dispersal in polygynous mammals. The predominant explanation is traceable back to Greenwood's () ideas of how successful philopatric or dispersing individuals are at gaining mates Cited by: 8.

  • 1. Dispersal in many species is sex‐biased. Greenwood (, Animal Behaviour, 28, –) hypothesized that the direction of sex bias was dependent on the mating system, and suggested that female‐biased dispersal in birds is associated with monogamy and resource defence by males, while mammalian male‐biased dispersal is associated with polygyny and male defence of directorymis.info by: In many species, dispersal is different between genders, leading to sex-biased dispersal. Several theoretical hypotheses have been proposed to explain the evolution of this bias: the resource competition hypothesis proposed by Greenwood, the local mate competition hypothesis, and the inbreeding avoidance hypothesis.
