Scale-Dependent Effects of a Heterogeneous Landscape on Genetic Differentiation in the Central American Squirrel Monkey (Saimiri oerstedii) [PDF]
PLoS ONE, 2012 Landscape genetic studies offer a fine-scale understanding of how habitat heterogeneity influences population genetic structure. We examined population genetic structure and conducted a landscape genetic analysis for the endangered Central American ...

Cryptic diversity in a gastrointestinal acanthocephalan of New World primates from Costa Rica [PDF]
Scientific Reports, 2023 Prosthenorchis elegans is a worm of the family Archiacanthocephala that infects non-human primates in the Americas, producing an intestinal pathology that may compromise the life of its hosts.

Two hundred and five newly assembled mitogenomes provide mixed evidence for rivers as drivers of speciation for Amazonian primates. [PDF]
Mol Ecol, 2022 Abstract Mitochondrial DNA remains a cornerstone for molecular ecology, especially for study species from which high‐quality tissue samples cannot be easily obtained. Methods using mitochondrial markers are usually reliant on reference databases, but these are often incomplete.

Environmental factors associated With Toxoplasma gondii Exposure in Neotropical Primates of Costa Rica [PDF]
Frontiers in Veterinary Science, 2020 The apicomplexan parasite Toxoplasma gondii (T. gondii) has been found in more than 350 species of homoeothermic vertebrates in diverse climates and geographic areas. In most animals, T. gondii produces mild or asymptomatic infection.

Color vision and niche partitioning in a diverse neotropical primate community in lowland Amazonian Ecuador. [PDF]
Ecol Evol, 2021 Neotropical primates exhibit substantial variation within and between species in color vision abilities; however, little work has explored interspecific variation in a single primate community. In this study, we genotyped functional variation in the middle‐to‐long‐wavelength opsin gene in populations of five sympatric primate species at the Yasuní ...

The influence of the forest corridors to the north of the Andes on the diversification of the bright-rumped Attila, Attila spadiceus (Passeriformes, Tyrannidae), during the climatic oscillations of the middle Pleistocene. [PDF]
Ecol EvolOur findings highlight the significance of Pleistocene Forest corridors north of the Andes as the key factor maintaining communication before the separation of the lineages of A. spadiceus. We highlight the absence of any significant differentiation between the disjunct Amazonian and Atlantic Forest populations, both part of the Cis‐Andean lineage. The

The Central American Squirrel Monkey (Saimiri oerstedii): Introduced Hybrid or Endemic Species?
Molecular Phylogenetics and Evolution, 2000 Although squirrel monkeys (Saimiri spp., Primates: Cebidae) are abundant and widespread in South America, the disjunct Central American species, Saimiri oerstedii, has been restricted to the Pacific wet lowlands of Costa Rica and Panama since the earliest historical records.

Analysis of the Hypothetical Population Structure of the Squirrel Monkey (Saimiri oerstedii) in Panamá [PDF]
, 2003 The Central American squirrel monkey (Saimiri oerstedii) is an endemic species from the coast of the Pacific Ocean to southeast Costa Rica and southwest Panama (Hershkovitz, 1984). Three common species (S. ustus, S. sciureus, and S. boliviensis) are found in South America and are distributed in the tropical forests of the Guayanas, the Amazon basin ...
