Between dunes and estuary: Forecasting mangrove forest change on primate culture and isolated livelihoods in Maranhão, Brazil

Geo: Geography and Environment
The unique ecological conditions of the mangrove forests in the Rio Preguiças Estuary, Maranhão, Brazil, support a culturally isolated population of bearded capuchin monkeys (Sapajus libidinosus) and contribute to the livelihoods and economy of the local

Anatomical Description of the Main Gyri and Sulci of the Telencephalon of Alouatta belzebul. [PDF]

Anat Histol Embryol
ABSTRACT The Alouatta belzebul is a species of howler monkey, of the Atelidae family and genus Alouatta. It is endemic in Brazil and has a separate geographic distribution, with two populations occurring: in the Amazon and in the Atlantic Forest on the coast of Northeast Brazil. The species is classified as ‘vulnerable’, and this is mainly justified by

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

Contexts of Anointing Behavior in a Group of Blond Capuchin Monkeys (Sapajus flavius) Inhabiting an Atlantic Forest Fragment. [PDF]

Am J Primatol
Wild blond capuchin anoints with millipede species that secrete a chemical capable of repelling ectoparasites, suggesting a self‐medicative function. Social and solitary anointing bouts occurred at similar frequencies, but with greater engagement by adult males, indicating that anointing is a multifunctional behavior.

Hand preference in wild crab‐eating capuchin monkeys (Sapajus libidinosus) in the coastal area of Northest Brazil

American Journal of Primatology, 2023
Handedness is a fundamental human trait, although recent research, especially on nonhuman primates, has shown that it is displayed by other animals as well (e.g., chimpanzees, gorillas).

Electrocutions in Free-Ranging Platyrrhine Nonhuman Primates: Diagnostic Features for a Threatening Condition. [PDF]

Am J Primatol
Epidemiological and pathological features of electrocutions in free‐ranging new‐world monkeys. ABSTRACT Electrical accidents pose a considerable threat to wildlife in anthropized regions, particularly arboreal mammals, as evidenced by cases of electrocutions in nonhuman primates (NHPs). This study characterized the frequency, anatomic distribution, and

Synchronous Pleural and Peritoneal Mesothelioma in a Free‐Ranging Capuchin Monkey (Sapajus libidinosus)

Journal of Medical Primatology
A free‐ranging capuchin monkey developed a synchronous biphasic pleural and peritoneal mesothelioma, a rare form of this tumor. Exophytic nodules were dispersed over the serosal surfaces, showing marked microscopical malignant features composed of both ...

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.

The impact of hybridization on upper first molar shape in robust capuchins (Sapajus nigritus x S. libidinosus)

Dental Anthropology, 2021
To better understand the impact of hybridization on development and morphology, I analyze an understudied phenotype in hybrid morphology research: tooth shape.
