Some oxyurids (nematoda) from neotropical primates

Zeitschrift f�r Parasitenkunde, 1964
1. A new species, Trypanoxyuris (Paraoxyuronema) tamarini, is described from Tamarinus nigricollis in Peru and T. (T.) sceleratus is reported from Saimiri sciurea in Peru and Colombia; T. (T.) lagothricis from Lagothrix cana and T. (T.) interlabiata from Aotes trivirgatus—both in Peru.

Behavioural Thermoregulation in a Small Neotropical Primate

Ethology, 2014
AbstractThe maintenance of body temperature in endothermic animals imposes considerable metabolic costs that vary with air temperature fluctuations. To minimise these costs, endotherms can adopt certain behaviours to adjust the pattern of heat transfer between their bodies and the environment.

DNA fingerprinting in three species of neotropical primates

American Journal of Primatology, 1996
DNA 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 ...

The Neotropical Primate Adaptation to Nocturnality

1996
The 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, 1990
AbstractThe 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, 1973
AbstractDuring 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, 1994
AbstractThere 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, 2017
Monkeys 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 ...
