The Neotropical Primate Adaptation to Nocturnality
1996The only primate with a nocturnal lifestyle in the neotropics is Aotus, the owl monkey. The genus is found from Panama to northern Argentina, and is very diverse. Twelve karyotypically distinct forms have diploid chromosome counts ranging from 46-58 (Hershkovitz, 1983; Ma et al., 1985; Pieczarka et al., 1993) and recent morphological and molecular ...

Primate origins: Lessons from a neotropical marsupial
American Journal of Primatology, 1990AbstractThe didelphid Caluromys shows evolutionary convergence towards prosimians in having a relatively large brain, large eyes, small litters, slow development, and agile locomotion. The selection pressures that favored the emergence of primate‐like traits in Caluromys from a generalized didelphid ancestor may be analogous to the selection pressures ...

Observations on two types of neotropical primate intertaxa associations
American Journal of Physical Anthropology, 1973AbstractDuring a socioecological field study of Colombian spider monkeys, data were collected on spatial associations and social and ecological interactions among free‐ranging Ateles belzebuth, Alouatta seniculus, Cebus apella, and Saimiri sciureus.

Use of neotropical and Malagasy primate species in biomedical research
American Journal of Primatology, 1994AbstractThere are 16 genera with 87 species of Neotropical primates, of which 18 (20.7%) are endangered. Only a handful of Neotropical species are utilized in biomedical research, and, of these, none are currently endangered. The few species utilized in biomedicine that are threatened in the wild are now bred largely from captive colonies.

The Monkeying of the Americas: Primate Biogeography in the Neotropics
Annual Review of Anthropology, 2017Monkeys first arrived in the Neotropics about 36 Ma, and the ancestry of all living Neotropical primates (Platyrrhini) traces to a single common ancestral population from 24 to 19 Ma. The availability of lush Amazonian habitat, the rise of the Andes, the transition from the lacustrine to riverine system in the Amazon Basin, and the intermittent ...

Assessing habitat utilization by neotropical primates: A new approach
Primates, 2002This study aims to ascertain habitat utilization, in relation to forest structural variation, by a multi-species group of primates in tropical lowland rainforest in Southeast Peru during dry season. A new approach to assessing habitat utilization was used. Habitat variation was described by structural and indicator variables collected in quadrats along

Emergence of Canine Distemper Virus in Brazilian Neotropical Primates
Journal of Medical PrimatologyABSTRACT Canine distemper virus (CDV) has markedly expanded its known host range over the recent past decades. CDV infection has been reported in old‐world primates of the genus Macaca , with reports between the 1980s and 2008 in Japan and China.

Primate Conservation Priorities in the Neotropical Region
1986Neotropical primates are found from southern Mexico, through central America and northern South America south as far as southern Brazil and northern Argentina (Fig. 16.1) and, with the exception of Chile and Uruguay, occur in all mainland South and Central American countries and on a few Caribbean islands as well. Sixteen genera and some 65 species are
