First report of Dipetalonema gracile in a captive Marcgrave's capuchin monkey (Sapajus flavius) in northeastern Brazil: Scientific communication

Semina: Ciências Agrárias, 2022
Parasitic infections are important concern to the Wildlife Conservation Biology, particularly in endangered species. Herein, we report a parasitism by Dipetalonema gracile Rudolphi, 1809 (Spirurida, Filarioidea, Onchocercidae), in the peritoneal cavity ...

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

The Anatomical Record, EarlyView.
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.

Effect of Site Attributes and Matrix Composition on Neotropical Primate Species Richness and Functional Traits: A Comparison Among Regions

Diversity, 2019
Fragmentation threatens biodiversity and forest-dwelling animals can be especially vulnerable. Neotropical primates inhabit forests and play ecological roles in maintaining forest biodiversity. Currently, many primate communities are restricted to forest

Unrewarded Object Combinations in Captive Parrots [PDF]

Animal Behavior and Cognition, 2014
In primates, complex object combinations during play are often regarded as precursors of functional behavior. Here we investigate combinatory behaviors during unrewarded object manipulation in seven parrot species, including kea, African grey parrots and
