From armadillos to sloths: Patterns and variations in xenarthran coronary anatomy

The Anatomical Record, Volume 309, Issue 8, Page 2199-2220, August 2026.
Abstract Species of the superorder Xenarthra play a vital ecological role in the Neotropics. Despite their evolutionary significance, anatomical studies on their coronary circulation remain scarce. This study investigated the coronary anatomy of 82 hearts from nine Xenarthra species across the Dasypodidae, Myrmecophagidae, and Bradypodidae.

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 .

Ecology and evolution of pyrazines in insects

Biological Reviews, Volume 101, Issue 4, Page 1937-1959, August 2026.
ABSTRACT Chemical communication is the oldest and most widespread form of signalling among and within organisms. Among the many compounds involved in such communication, pyrazines – nitrogen‐containing heterocyclic molecules – are especially intriguing due to their widespread occurrence across the tree of life, from bacteria and fungi to insects and ...

(Braun, 1901) in Neotropical primates kept in captivity

, 2021
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,

First case of albinism registered for Ateles chamek (Humboldt, 1812) [PDF]

, 2022
Albinism is rarely documented amongst Neotropical mammals, especially in primates, for which only a few cases have been reported. In this paper, we report the first case of albinism in a wild black-faced black spider monkey

Possible fruit protein effects on primate communities in madagascar and the neotropics. [PDF]

PLoS ONE, 2009
The ecological factors contributing to the evolution of tropical vertebrate communities are still poorly understood. Primate communities of the tropical Americas have fewer folivorous but more frugivorous genera than tropical regions of the Old World and

Flower Feeding and Reproductive Timing in Spix's Night Monkeys (Aotus vociferans): Evidence From Arboreal Camera Traps

Ecology and Evolution, Volume 16, Issue 7, July 2026.
This article provides new insights into the diet and reproductive biology of the Spix's night monkeys (Aotus vociferans). This evidence was collected using arboreal camera traps in a tropical mountain rainforest in Southern Ecuador, where documented information on this primate is rare.

Patch size, functional isolation, visibility and matrix permeability influences neotropical primate occurrence within highly fragmented landscapes. [PDF]

PLoS ONE, 2015
Forest fragmentation and habitat loss are among the major current extinction causes. Remaining fragments are mostly small, isolated and showing poor quality. Being primarily arboreal, Neotropical primates are generally sensitive to fragmentation effects.
