“…The Sáo Francisco Xavier population deserves further study being the only one known from the southern Serra da Mantiqueira, an area of different climate and vegetation, including as it does Araucaria forest, to the coastal massifs. The muriquis observed at this locality evidently belong to the nominal subspecies (black-faced), as is so for others collected along the Serra da Mantiqueira north to the Serra dos Orgdos (Rio de Janeiro) (Coimbra-Filho et al, 1993;Lemos de Sá et al, 1993). If the Serra da Mantiqueira is a barrier between the southern (nominal) and northern (B.a.hypoxanthus) subspecies, it is probably due to vegetational changes at higher elevations and on the western side of the mountains.…”

Primates are important indicators for tropical forests as a fundamental component in the establishment of strategies for biodiversity conservation in biomes, regions and countries. Priority setting at the species’ level is dependent on taxonomic studies and the evaluation of population status. The most recent listing of the Neotropical primates recognised the existence of 16 genera, 98 species and 202 species and subspecies. Sixteen of these primates are critically endangered, 19 are endangered, and a further 35 are vulnerable according to the Mace-Lande system recently adopted by the World Conservation Union (IUCN). Thirty-five percent of the Neotropical primate taxa are threatened. In this paper we review the conservation status of these threatened primates, and analyse their distributions in 21 countries and seven phytogeographic regions, evaluating richness, endemism and number of threatened taxa.

Evolution of sexual dimorphism in body weight in platyrrhines

Neotropical primates show a remarkable range in body size, spanning two orders of magnitude from the tiny pygmy marmosets (100 g) to the woolly spider monkeys (11,000 + g). Even among the "smaller" platyrrhines, the range is large. In addition, these primates demonstrate a wide diversity in degrees and directions of sexual dimorphism, in both body size and canine size, from marked positive dimorphism (males larger than females), through monomorphic species, to negative dimorphism. Potential correlates or causes of the patterns of dimorphism in body size are investigated, including overall body size, natural selection for life history strategies, sexual selection, diet, habitat, and phylogenetic inertia. Focus is especially on those genera that show species-specific variation in dimorphism (e.g., Saguinus, Pithecia). Results are contrary to those for cross-primate or catarrhine studies, but complementary to recent studies on strepsirhines. They suggest that sexual selection is the primary determinant of degree and pattern of sexual dimorphism in platyrrhines, but that there is also a dietary effect. Natural selection may have some effect, although not the parameters analyzed here. Body size, habitat (primary vs. secondary forest preference), and phylogenetic inertia or constraints do not have any effect on the presence of sexual dimorphism in body weights in New World monkeys. o
