How far do Neotropical primates disperse seeds?
American Journal of Primatology, 2017Seed dispersal distance (SDD) is a vital component of vertebrate‐mediated seed dispersal process: the average distance at which seeds are deposited away from the parent plant represents the starting template of plant regeneration. We present a simple model to explain and predict observed measures of average dispersal distance and we hypothesize that it

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.

Hybridization Between Neotropical Primates with Contrasting Sexual Dichromatism
International Journal of Primatology, 2018Hybridization is relatively well documented among Old World primates, but poorly investigated among New World monkeys. We investigated hybridization between the sexually dichromatic howlers Alouatta caraya and Alouatta guariba clamitans, whose lineages diverged ca. 5 million years ago.

A fully resolved genus level phylogeny of neotropical primates (Platyrrhini)
Molecular Phylogenetics and Evolution, 2009There are more than 125 species of extant New World monkeys (Primates: Platyrrhini) found in approximately 15 genera. The phylogenetic relationships of these neotropical primates have been extensively studied from a molecular perspective. While these studies have been successful at inferring many of the relationships within the platyrrhines, key ...

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

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 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
