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 ...

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.

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.

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

ASPM and the evolution of cerebral cortical size in a community of New World monkeys. [PDF]
PLoS ONE, 2012 The ASPM (abnormal spindle-like microcephaly associated) gene has been proposed as a major determinant of cerebral cortical size among primates, including humans.

Plant Diversity in the Diet of Costa Rican Primates in Contrasting Habitats: A Meta-Analysis
Diversity, 2023 In human-modified tropical landscapes, the survival of arboreal vertebrates, particularly primates, depends on their plant dietary diversity. Here, we assess the diversity of plants included in the diet of Costa Rican non-human primates, CR-NHP (i.e ...

Ecological correlates of space use patterns in wild western lowland gorillas
American Journal of Primatology, Volume 82, Issue 9, September 2020., 2020 Abstract The distribution of resources is a crucial determinant of animals' space use (e.g., daily travel distance, monthly home range size, and revisitation patterns). We examined how variation in ecological parameters affected variability in space use patterns of western lowland gorillas, Gorilla gorilla gorilla.
