Ecology and social organization of squirrel monkeys Saimiri spp specific characteristics or constraints of habitat? Ecologie et organisation sociale des singes-ecureuils Saimiri spp caracteristiques specifiques ou contraintes de lhabitat?

Squirrel monkeys (Saimiri spp.) are small Platyrrhines widespread in Neotropical forests. Studies of taxonomy of the genus and phylogenetic relationships between clades are complex and still ongoing (see Lavergne et al., this volume). Because of a poor conservation status of the species in Central America (Rylands et al., 1997), ecoethological patterns of Saimiri oerstedii have been extensively studied. Conversely, the other species are much more common and are distributed over the Amazon area in various forest types including degraded areas, and are much less studied. According to an overview of available data, the main ecologic patterns including diet, habitat use, and role in primate community, are rather stable across species. Some differences in densities, home range sizes, are recorded, but are related to types of habitat, rather than to species. Alternatively, social organizations within squirrel monkeys troops are strongly diverse, with a matriarcal structure in Saimiri boliviensis, a patriarcal structure in S. sciureus, and an egalitarian organization in S. oerstedii. These differences are supported by high genetic variations between these 3 clades, and are explained by the patterns of distribution and phenology of some major key fruits species. A recent ecoethological fieldwork added further information. A S. sciureus population located in an isolated and heavily modified forest habitat was studied in French Guiana, and led to the conclusion that the social organization may split towards the most efficient system according to resources availability. Indeed, the vegetation patterns in this habitat were close to those described in the Peruvian forests, and the social organization of the groups were similar to that of S. boliviensis inhabiting these forests. Together with their small size, their generalist morphology, their non-specialized diet, their population dynamics, this plasticity of social organization has to be considered as a major component explaining the ecological success of the genus.
