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

Areas of high risk for mammalian biodiversity and nature's contributions to people under global warming

Conservation Science and Practice, EarlyView.
Climate change has reached unprecedented levels, causing frequent extreme events like droughts and fires. These changes are driving a sharp rise in extinction risk for mammals and threatening key Nature's Contributions to People (NCP) such as clean water, air quality, and climate regulation.

Morphological variation in atlas and axis of Neotropical spiny rats (Rodentia, Echimyidae)

The Anatomical Record, Volume 309, Issue 10, Page 2873-2896, October 2026.
Abstract The unique morphologies of the first two cervical vertebrae, the atlas and axis, represent a significant innovation in mammalian evolution. These structures support the weight of the head and enable intricate movements of the head and neck.

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 ...

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,

Arboreal and Terrestrial Frugivore Vertebrate Assemblage Diversity and Composition Vary With Disturbance Histories in Guianan Forests

Ecology and Evolution, Volume 16, Issue 10, October 2026.
This study examined the impact of human disturbances on arboreal and terrestrial fruit‐consuming vertebrate assemblages across three tropical forest sites in French Guiana. While species richness remained consistent across sites, results revealed significant variations in visitation rates and a shift in dominant species.

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.

Seasonality and plasticity in the use of native and introduced plant resources by a large forest parrot

Ibis, Volume 168, Issue 4, Page 1572-1588, October 2026.
Human‐induced environmental change is reshaping plant communities, requiring native animals to adapt their foraging behaviour to track and exploit novel food resources. Trees such as pines (Pinus spp.) introduced for plantation forestry outside of their native ranges often become naturalized.
