Hand preference predicts behavioral responses to threats in Barbary macaques

American Journal of Primatology, Volume 85, Issue 7, July 2023., 2023
Hand preference predicts behavioral in Barbary macaques. Abstract The structure and functioning of the brain are lateralized—the right hemisphere processes unexpected stimuli and controls spontaneous behavior, while the left deals with familiar stimuli and routine responses.

Comparative gastrointestinal organ lengths among Amazonian primates (Primates: Platyrrhini)

American Journal of Biological Anthropology, Volume 181, Issue 3, Page 440-453, July 2023., 2023
Principal coordinates analysis (PCoA) comparing the individual gastrointestinal variation based on Euclidean distance (51% of explanation for the axis 1 and 26% of axis 2), where CeQ, cecal quotient; CoQ, colonic quotient; EQ, esophageal quotient; GQ, gastric quotient; IQ, small intestine quotient; RQ, rectal quotient. Ellipses represent 95% confidence

Beans with bugs: Covert carnivory and infested seed selection by the red‐nosed cuxiú monkey

Biotropica, Volume 55, Issue 3, Page 579-593, May 2023., 2023
The red‐nosed cuxiu monkey specializes in eating un‐ripe seeds. Our study show they prefer those that are infested with larval insects. We believe this to be because the seeds they eat are very low in protein, while larval insects are protein‐rich and also easily digested.

Variation in Pubic Symphysis Fusion Across Primates: Implications for Obstetric Adaptation. [PDF]

Am J Biol Anthropol
Variation in the fusion of the pubic symphysis in primate pelves. ABSTRACT Objectives The unfused human pubic symphysis has been interpreted as an obstetric adaptation to facilitate the passage of a large‐brained baby through a relatively small, bipedally adapted pelvis.

Z‐nucleic acids: Uncovering the functions from past to present

European Journal of Immunology, Volume 52, Issue 11, Page 1700-1711, November 2022., 2022
This article summarizes the research on Z‐nucleic acid historically and highlights the milestones in this field, including the discovery, characterization of the Z‐nucleic acids and their biological functions mediated by interacting with Z‐nucleic acid binding proteins such as ZBP1, ADAR1, and so on.

Phylogenetic studies of the genus Cebus (Cebidae-Primates) using chromosome painting and G-banding

BMC Evolutionary Biology, 2008
Background Chromosomal painting, using whole chromosome probes from humans and Saguinus oedipus, was used to establish karyotypic divergence among species of the genus Cebus, including C. olivaceus, C. albifrons, C. apella robustus and C.

Wild meat trade over the last 45 years in the Peruvian Amazon

Conservation Biology, Volume 36, Issue 2, April 2022., 2022
Abstract The trade in wild meat is an important economic component of rural people's livelihoods, but it has been perceived to be among the main causes of the decline of wildlife species. Recently, the COVID‐19 pandemic has brought to light an additional concern of wildlife markets as a major human‐health challenge.

Who is the expert? Evaluating local ecological knowledge for assessing wildlife presence in the Peruvian Amazon

Conservation Science and Practice, Volume 4, Issue 2, February 2022., 2022
Abstract Amazonian wildlife population studies often employ conventional biological survey methods to assess species presence but a growing number of studies are making use of local ecological knowledge (LEK) household surveys. Despite concerns in the scientific community over the accuracy and precision of LEK, scant research to date compares data from

A phylogenomic perspective on the robust capuchin monkey (Sapajus) radiation : first evidence for extensive population admixture across South America [PDF]

, 2018
Phylogenetic relationships amongst the robust capuchin monkeys (genus Sapajus) are poorly understood. Morphology-based taxonomies have recognized anywhere from one to twelve different species.

Chromosome Evolution in New World Monkeys (Platyrrhini) [PDF]

, 2012
During the last decades, New World monkey (NWM, Platyrrhini, Anthropoideae) comparative cytogenetics has shed light on many fundamental aspects of genome organisation and evolution in this fascinating, but also highly endangered group of neotropical ...
