Taxonomic and sex differences in sagittal cresting among gracile and robust capuchin monkeys. [PDF]

J Anat
In this study, I show that there are interspecific differences in the frequency and pattern of sagittal cresting among six capuchin species. Four of the six species show sagittal cresting, with Cebus capucinus showing a different sagittal cresting pattern to that observed in three robust capuchin species. All four crested species show sexual dimorphism

Behavioral Contagion in Wild Ecuadorian White-Fronted Capuchins (Cebus aequatorialis). [PDF]

Am J Primatol
White‐fronted capuchins exhibit scratching contagion, but neither the characteristics of the trigger, or of the partner's (sex, age class, or centrality), or of the dyad (combination of sex, combination of age class, or social bond) seem to modulate the likelihood of contagion.

Characterization of antimicrobial resistance profiles in Escherichia coli isolated from captive mammals in Ecuador. [PDF]

Vet Med Sci
Among 90 E. coli isolates from 70 mammals, significant resistance was found to ampicillin (52.22%), ceftriaxone (42.22%) and cefuroxime (42.22%), with 27.78% being ESBL‐producing. Notably, 66.67% of isolates showed resistance to at least one antibiotic, and 35.56% exhibited multiresistant phenotypes.

Tails in Action: Comparative Use of the Prehensile Tail and Substrate in Alouatta macconnelli, Sapajus apella, and Potos flavus. [PDF]

Am J Primatol
Barplot representing the frequencies (percentages) of positional behaviors in relation to tail use for Alouatta macconnelli (left), Potos flavus (middle), and Sapajus apella (right). For each species, the left barplot represents all positional behaviors, the middle one postural behaviors, and the right one locomotor behaviors.

Mitochondrial DNA for Phylogeny Building: Assessing Individual and Grouped mtGenes as Proxies for the mtGenome in Platyrrhines. [PDF]

Am J Primatol
ABSTRACT Phylogenetic trees are analytic tools used in primate studies to elucidate evolutionary relationships. Because of its relative ease to sequence and rapid evolution compared to nuclear genomes, mitochondrial DNA is frequently used for phylogeny building. This project evaluated the effectiveness of using individual or grouped mitochondrial genes

Nucleic acid degradation after long-term dried blood spot storage. [PDF]

Mol Ecol Resour
Abstract Collecting and preserving biological samples in the field, particularly in remote areas in tropical forests, prior to laboratory analysis is challenging. Blood samples in many cases are used for nucleic acid‐based species determination, genomics or pathogen research.

The distribution of bushmeat mammals in unflooded forests of the Central Amazon is influenced by poaching proxies

Ecology and Evolution, Volume 13, Issue 12, December 2023., 2023
Our study focuses on investigating the impact of anthropogenic factors on the occupancy of medium and large mammals in unflooded forests of the Central Amazon. Through a camera trapping survey conducted across 47 sampling sites during the dry season, we provide a comprehensive analysis of the influence of anthropogenic stressors on mammal occupancy ...
