Histopathological characterization of nephritides in the brown capuchin monkey, Cebus apella (Primates: Cebidae)

Revista de Biología Tropical, 2000
The renal lesions are of special importance in the captive primates. The most commonly pathologies are: pyelonephritis, nephrocalcinosis, glomerulonephritis, congenital malformations, hydronephrosis and functional diseases.

Impacted Bones: Can Extant Primates Help Identify Tool Use in Early Hominins? [PDF]

Evol Anthropol
ABSTRACT Despite recent advances pushing back the earliest record of tool use, how and when it first emerged in hominins, and the extent to which it featured amongst the numerous co‐existing species, remain critical questions in paleoanthropology. In addition to analyzing fossils and lithic toolkits, novel strides in understanding this might be made by

Non-Invasive Measures of DNA Methylation Capture Molecular Aging in Wild Capuchin Monkeys. [PDF]

Mol Ecol
ABSTRACT Elucidating the socio‐ecological factors that shape patterns of aging in long‐lived vertebrates is of broad interest to evolutionary biologists, geroscientists, and ecologists. However, research on aging in wild populations still faces challenges due to the difficulty of measuring cellular hallmarks of aging non‐invasively and the difficulty ...

Ontogenetic Changes in Intrinsic Hand and Foot Proportions in Chimpanzees, Pan troglodytes. [PDF]

Am J Biol Anthropol
ABSTRACT Objectives Ontogenetic trajectories in intrinsic hand and foot proportions are likely to vary in primates according to their locomotor adaptations. We analyzed the developmental trajectories of chimpanzees (Pan troglodytes), which exhibit particular locomotor adaptations related to suspensory and climbing abilities, testing whether autopodial ...

Occurrence of Antibodies Anti-Toxoplasma gondii in Captive Non-Human Primates From Pernambuco State, Brazil. [PDF]

J Med Primatol
ABSTRACT Wildlife captive populations are important tools for threatened species conservation, and early identification of diseases must be prioritized. In this study, we test for the presence of anti‐Toxoplasma gondii antibodies in non‐human primates at a Zoo from Pernambuco State, Brazil.

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.

Experimental Gastric Carcinogenesis in Cebus apella Nonhuman Primates

PLoS ONE, 2011
The evolution of gastric carcinogenesis remains largely unknown. We established two gastric carcinogenesis models in New-World nonhuman primates. In the first model, ACP03 gastric cancer cell line was inoculated in 18 animals. In the second model, we treated 6 animals with N-methyl-nitrosourea (MNU).

The presence of neuronal-specific nuclear protein (NeuN) in the circadian timing system of the capuchin monkey (Cebus apella)

Sleep Science, 2010
Background and objective: The circadian timing system (CTS) is composed of a group of specialized neuronal structures that establish a temporal organization of physiological and behavioral processes within precise patterns.
