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

open access: yesDiversity, 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]

open access: yesAnimal 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

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

open access: yesSemina: 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 ...

Selfish or altruistic? An analysis of alarm call function in wild capuchin monkeys, Cebus apella nigritus [PDF]

open access: yes, 2008
Alarm calls facilitate some antipredatory benefits of group living but may endanger the caller by attracting the predator's attention. A number of hypotheses invoking kin selection and individual selection have been proposed to explain how such behaviour

Ecology and evolution of pyrazines in insects

open access: yesBiological Reviews, EarlyView.
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 ...

Tool skill impacts the archaeological evidence across technological primates

open access: yesScientific Reports
The archaeological record offers insights into our evolutionary past by revealing ancient behaviour through stone and fossil remains. Percussive foraging is suggested to be particularly relevant for the emergence of tool-use in our lineage, yet early ...
