Role of Rivers as Geographical Barriers in Shaping Molecular Divergence of Neotropical Primates

Biotropica
We quantitatively tested the riverine barrier hypothesis and its influence on biogeographical distributions and molecular variation in New World monkeys (Parvorder: Platyrrhini). Using mitochondrial markers (cytochrome oxidase subunit II and cytochrome b)

Special issue: Comparative biogeography of Neotropical primates

Molecular Phylogenetics and Evolution, 2015
New research presented in this special issue of Molecular Phylogenetics and Evolution on the "Phylogeny and Biogeography of Neotropical Primates" greatly improves our understanding of the evolutionary history of the New World monkeys and provides insights into the multiple platyrrhine radiations, diversifications, extinctions, and recolonizations that ...

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.

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.

Histopathologic Patterns and Susceptibility of Neotropical Primates Naturally Infected With Yellow Fever Virus

Veterinary Pathology-Supplement, 2020
Yellow fever is an important zoonotic viral disease that can be fatal for both human and nonhuman primates. We evaluated histopathologic changes in free-ranging neotropical primates naturally infected with yellow fever virus (YFV) compared with ...

Anatomopathological lesions of infection caused by Platynosomum illiciens (Braun, 1901) in Neotropical primates kept in captivity

Journal of medical primatology, 2020
This study described the hepatobiliary anatomopathological lesions associated with trematode Platynosomum illiciens parasitism in Neotropical primates kept in captivity. In the evaluated organs, we observed portal fibrosis, biliary epithelial hyperplasia,

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 ...

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.

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 ...
