Mammal populations living on islands frequently difer from mainland conspeciics (or congenerics) in behaviour and/ or morphology. his is oten attributed to the ecological efects (changes in resource base) and genetic efects (limited genetic interchange and/ or founder efects). here are a number of mainland- based non- human primate species that also have island- inhabiting populations. The current chapter deals with one of these, the black and gold howler (A. caraya). In northern Argentina and southern Brazil, this species has populations that live on islands, characterized by looded forests, along the Parana and Uruguay rivers, while mainland populations inhabit natural fragmented forests and gallery forests along small rivers.
