Genetic diversity of neotropical primates: phylogeny, population genetics, and animal models for infectious diseases

, 2010
The classification of neotropical primates has been controversial, and different arrangements have been proposed based on disparate taxonomic criteria and on the traits selected for elucidating phylogenetic reconstructions, like morphologic characters ...

BIRD COMMUNITIES ALONG URBANIZATION GRADIENTS: A COMPARATIVE ANALYSIS AMONG THREE NEOTROPICAL CITIES [PDF]

, 2017
∙ Urbanization is expanding continuously over rural and natural areas and it is imperative to analyze its effect on bird communities. Although the impact of urbanization on bird communities in the Neotropical region has been explored by several authors ...

Population recovery of an endangered macaw enhances long‐distance seed dispersal via stomatochory

Oikos, EarlyView.
Seed dispersal by large, mobile vertebrates plays a key role in shaping plant spatial dynamics and community structure. However, how variation in animal population size influences the magnitude and spatial scale of seed dispersal remains poorly understood.

Multilevel societies in new world primates? Flexibility may characterize the organization of Peruvian red uakaris (Cacajao calvus ucayalii) [PDF]

, 2012
Researchers have described multilevel societies with one-male, multifemale units (OMUs) forming within a larger group in several catarrhine species, but not in platyrhines.

Historical Development of Zoo Tapir (Tapirus ssp.) Survivorship

Zoo Biology, EarlyView.
The survivorship of tapirs in zoos has improved significantly over historical time. ABSTRACT Tapirs (Tapirus spp.) are large, long‐lived herbivores native to Central and South America and Southeast Asia. All species are currently classified as Vulnerable (T. terrestris) or Endangered (other species) in the IUCN SSC Red List.

Belowground effects of ground‐dwelling large herbivores in forest ecosystems

Journal of Animal Ecology, EarlyView.
This study reviews how ground‐dwelling large herbivores affect forest soil and litter globally. Effects are context‐dependent, vary among species and forest types, and remain poorly studied in tropical forests, highlighting critical gaps in understanding nutrient cycling and ecosystem functioning.

From steps to home ranges: How habitat disturbance influences the movement drivers of an arboreal primate

Journal of Animal Ecology, EarlyView.
Challenging the narrative about howler monkeys' high resilience to anthropogenic changes, our multiscale analysis reveals the costs of habitat disturbance to their movement ecology. We identify thermal limitations, reduced travel efficiency, and significant spatial saturation.

The origin and evolution of neotropical primates

, 2008
A significant event in the early evolution of Primates is the origin and radiation of anthropoids, with records in North Africa and Asia. The New World Primates, Infraorder Platyrrhini, have probably originated among these earliest anthropoids morphologically and temporally previous to the catarrhine/platyrrhine branching .

Adaptive evolution of facial colour patterns in Neotropical primates [PDF]

Proceedings of the Royal Society B: Biological Sciences, 2012
The rich diversity of primate faces has interested naturalists for over a century. Researchers have long proposed that social behaviours have shaped the evolution of primate facial diversity. However, the primate face constitutes a unique structure where the diverse and potentially competing functions of communication, ecology and physiology intersect,

Body Size Regulates Niche Overlap Asymmetry in the Subtropical Andes Rain Shadow: Isotopic Paleoecology of Oligocene South American Ungulates

Integrative Zoology, EarlyView.
This study provides the first isotopic analysis of Oligocene mammals from Quebrada Fiera, Mendoza, Argentina, filling a major gap in South American paleontology. It reveals a latitudinal gradient in aridity due to the Andean rain shadow and highlights the role of (semi)permanent water bodies in sustaining diverse herbivore communities. Additionally, it
