Female Reproductive System Neoplasms in Neotropical Primates. [PDF]

J Med Primatol
ABSTRACTBackgroundThere are no previous descriptions of the prevalence of spontaneous female reproductive neoplasms in neotropical primates.MethodsA 6‐year study of pathological records from the Anatomy Pathology Sector from the Federal Rural University of Rio de Janeiro (SAP/UFRuralRJ) was conducted. All cases of female nonhuman primate taxa belonging

Proximate causes of the red face of the bald uakari monkey (Cacajao calvus) [PDF]

Royal Society Open Science, 2015
In social species, such as primates, facial appearances transmit a variety of social signals. Although it is suggested that the intense red colour of the face of the bald uakari monkey might be an indicator of health, this hypothesis still has not been ...

Vocalizations Reveal Species Differences in Endangered Lion Tamarins (Primates, Callitrichidae). [PDF]

Am J Primatol
Spectral parameters of vocalizations distinguish lion tamarin species. Peak frequency, center frequency, and frequency at 5% and 95% were the most informative measures for separating species, with the trill being the vocalization that showed the most differences, and Leontopithecus caissara being the most distinct species of all.

Infectious diseases of neotropical primates

Brazilian Journal of Veterinary Pathology, 2023
Neotropical primates are represented by more than 200 species and subspecies distributed in five families. Considering that some of these species are considered endangered, disease investigation in these populations is critical for conservation strategies. Therefore, an increasing number of studies and publications on this topic became available in the

Workshop Summary: Neotropical Primates in Biomedical Research [PDF]

ILAR Journal, 2011
This report summarizes presentations and discussions at an NIH-sponsored workshop on Neotropical Primates in Biomedical Research, held in September 2010. Neotropical primates (New World monkeys), with their smaller size, faster maturation, and shorter lifespans than Old World monkeys, are efficient models and present unique opportunities for studying ...
