The primates of the Neotropics: genomes and chromosomes

Cytogenetic and Genome Research, 2004
The classification of neotropical primates has been controversial. Different arrangements have been proposed, depending on taxonomic criteria and on the traits selected for phylogenetic reconstructions. These include gross morphologic characters, karyotypic attributes and DNA sequence data of nuclear and mitochondrial genes and of repetitive genomic ...

Neotropical primate conservation

Journal of Human Evolution, 1989
Abstract The greatest threat to Neotropical primates is the loss of tropical forest for agriculture, ranching, commercial logging and hydroelectric projects. Hunting of primates for consumption or sale and live capture for the pet trade and for biomedical purposes is also a threat to certain species. Twenty-eight of the 76 Neotropical primate species

Identification of Bacterial Infection in Neotropical Primates

Microbial Ecology, 2013
Emerging infectious diseases usually arise from wild animal populations. In the present work, we performed a screening for bacterial infection in natural populations of New World primates. The blood cell bulk DNAs from 181 individuals of four Platyrrhini genera were PCR screened for eubacterial 16S rRNA genes.

Alpha satellite DNA in neotropical primates (Platyrrhini)

Chromosoma, 1994
The alpha satellite DNA of Old World (catarrhine) primates usually consists of similar, but not identical, ca. 170 bp sequences repeated tandemly hundreds to thousands of times. The 170 bp monomeric repeats are components of higher-order repeats, many of which are chromosome specific.

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 ...
