DNA fingerprinting in three species of neotropical primates
American Journal of Primatology, 1996DNA fingerprinting allows the simultaneous detection of a large number of hypervariable loci consisting of highly polymorphic tandem repeat units that are extensively dispersed in the genome. With the 33.6 human minisatellite probe, hypervariable fragments were detected, for the first time, in the genome of three different species of wild-caught ...

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

Oxytocin is a mammalian neuropeptide hormone that mediates behaviours important to reproduction. Despite almost universal amino acid sequence conservation across most groups of mammals, several unique forms have been reported across Neotropical ...

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.

The Brazilian Amazon is endemic for malaria and natural infections by Plasmodium spp. have been detected in Neotropical primates. Despite the diversity of primate species in the region, studies on infections by these agents are limited.

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 ...

Metabolic bone disease in an extinct neotropical primate
International Journal of PaleopathologyThis work evaluates the potential presence of bone disease in an extinct primate from late Pleistocene of Brazil.The skull and post crania of an extinct platyrrhine primate, curated by the Museu de Ciências Naturais PUC, Brazil.Pathological changes were noted via analysis of radiographic images and CT of the affected bones.The lesions noted include ...

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 ...
