Primatas do estado de Rondônia
No Estado de Rondônia, localizado na região oeste da Amazônia brasileira, encontramos uma diversidade de ecossistemas, como a floresta amazônica, o Pantanal e o Cerrado. Atualmente, são conhecidas 29 espécies de primatas na região, porém muitas delas ainda necessitam de reavaliação taxonômica e de distribuição. Rondônia faz parte do "Arco do desmatamento", uma área com altas taxas de desmatamento que ameaçam a sobrevivência de várias espécies de …
Impending extinction crisis of the world’s primates
Impending extinction of the world’s primates due to human activities; immediate global attention is needed to reverse the trend.
Reduced range of the endangered crested capuchin monkey ( Sapajus robustus ) and a possible hybrid zone with Sapajus nigritus
The crested capuchin monkey ( Sapajus robustus ) is an endangered species endemic to the highly fragmented Atlantic Forest of Brazil. Surveys for S. robustus were carried out over a 25‐month period (2003–2005) to obtain more precise geographical limits for the western range of the species. Previously published localities for S. robustus were mapped, and each point was given a 25‐km radius “buffer zone.” The largest forest remnants in the buffer z…
Genetic Analysis of the Indri Reveals No Evidence of Distinct Subspecies
Re-description and assessment of the taxonomic status of Saguinus fuscicollis cruzlimai Hershkovitz, 1966 (Primates, Callitrichinae)
Primate taxonomy
Primatology as a discrete branch of science involving the study of primate behavior and ecology took off in the 1960s after discovery of the importance of primates as models for biomedical research and the realization that primates provide insights into the evolutionary history of humans. Osman Hill's unfortunately incomplete monograph series on the comparative anatomy and taxonomy of the primates 1 and the Napiers' 1967 A Handbook of Living Prim…
How Different Are Robust and Gracile Capuchin Monkeys? An Argument for the Use of S apajus and C ebus
Capuchin monkey behavior has been the focus of increasing numbers of captive and field studies in recent years, clarifying behavioral and ecological differences between the two morphological types: the gracile and the robust capuchins (also referred to as untufted and tufted). Studies have tended to focus on the gracile species C ebus capucinus (fewer data are available for C . albifrons , C . olivaceus , and C . kaapori ) and on C ebus apella , …
C ebus Phylogenetic Relationships
The untufted, or gracile, capuchin monkeys are currently classified in four species, C ebus albifrons , C . capucinus , C . olivaceus , and C . kaapori , with all but C . kaapori having numerous described subspecies. The taxonomy is controversial and their geographic distributions are poorly known. C ebus albifrons is unusual in its disjunct distribution, with a western and central A mazonian range, a separate range in the northern A ndes in C ol…
The range of the golden-mantle tamarin, Saguinus tripartitus (Milne Edwards, 1878)
A detailed understanding of the range of the golden-mantle tamarin, Saguinus tripartitus (Milne Edwards, 1878), in Amazonian Peru and Ecuador is of particular relevance, not only because it is poorly known but also because it was on the basis of its supposed sympatry with the saddleback tamarin (S. fuscicollis lagonotus) that Thorington (Am J Primatol 15:367-371, 1988) argued that it is a distinct species rather than a saddleback tamarin subspeci…

Census and distribution of the golden lion tamarin ( Leontopithecus rosalia )
During 1990–1992, a survey of the golden lion tamarin, Leontopithecus rosalia , was carried out throughout its known distribution area. Forest remnants were identified by visual interpretation of Landsat‐TM satellite images. Localities occupied by L. rosalia were first identified by interviews with local people. All forests more than 20 ha in size, and for which two or more interviews suggested the presence of the species, were surveyed using “pl…
Habitat Loss and Extinction in the Hotspots of Biodiversity
Nearly half the world's vascular plant species and one‐third of terrestrial vertebrates are endemic to 25 “hotspots” of biodiversity, each of which has at least 1500 endemic plant species. None of these hotspots have more than one‐third of their pristine habitat remaining. Historically, they covered 12% of the land's surface, but today their intact habitat covers only 1.4% of the land. As a result of this habitat loss, we expect many of the hotsp…
Feeding behavior of Geoffroy's marmoset (Callithrix geoffroyi) in an Atlantic forest fragment of South-eastern Brazil
An assessment of the diversity of New World primates
An understanding of the full diversity of the primates is vital for priority-setting for conservation purposes, both for captive breeding and in situ conservation measures. Here we provide a full, annotated listing of the Neotropical primate species and subspecies resulting from a workshop, “Primate Taxonomy for the New Millennium”, which brought together experts in primate taxonomy and biogeography, morphologists and geneticists. It was organize…

Habitat and the evolution of social and reproductive behavior in callitrichidae
Habitat and the evolution of social and reproductive behavior in callitrichidae
The numerous remarkable traits characterizing the ecology and behavior of callitrichids have inspired considerable research and discussion of the flexible mating system (cases of monogamy, polygyny, and polyandry), cooperative breeding, reproductive inhibition by dominant females, rapid reproductive rate, significance of dietary differences (gum feeding, frugivory, and insectivory), and demographics and social characteristics of the four genera, …
