Abstract

Deforestation is associated with increased environmental heterogeneity, unpredictability, and stress that may modify patterns of beahavior in mammalian populations. In particular, habitat disturbance and other anthropogenic effects appear to be increasing the incidence of bisexual dispersal. These events are analyzed in terms of benefits and costs of dispersal to individuals of either sex. Implications for conservation are discussed.
