Stone tools differences across three capuchin monkey populations: food’s physical properties, ecology, and culture [PDF]

Scientific Reports, 2022
Robust capuchin monkeys (Sapajus) are known for processing mechanically challenging foods, having morphological adaptations to do so. However, several populations go beyond body limitations by using stone tools to expand their food range.

Wild bearded capuchin monkeys (Sapajus libidinosus) strategically place nuts in a stable position during nut-cracking. [PDF]

PLoS ONE, 2013
Humans can use hand tools smoothly and effectively in varying circumstances; in other words, skillfully. A few other species of primates crack encased foods using hammer tools and anvils. Are they skilled?

Lineage-specific serology confirms Brazilian Atlantic forest lion tamarins, Leontopithecus chrysomelas and Leontopithecus rosalia, as reservoir hosts of Trypanosoma cruzi II (TcII) [PDF]

Parasites & Vectors, 2016
Background Trypanosoma cruzi, the agent of Chagas disease in humans, has a vast reservoir of mammalian hosts in the Americas, and is classified into six genetic lineages, TcI-TcVI, with a possible seventh, TcBat.

Integrating culture into primate conservation. [PDF]

Philos Trans R Soc Lond B Biol Sci
Primates exhibit the richest cultural repertoire among animal taxa, spanning foraging, communication, sociality and tool use. Understanding the cultural behaviours of primates has strongly influenced the study of animal behaviour and challenged ...

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

Ontogenetic Biomechanics of Tufted (\u3ci\u3eSapajus\u3c/i\u3e) and Untufted (\u3ci\u3eCebus\u3c/i\u3e) Capuchin Mandibles [PDF]

American Journal of Biological Anthropology, Volume 185, Issue 2, October 2024.
Objectives Cortical bone geometry is commonly used to investigate biomechanical properties of primate mandibles. However, the ontogeny of these properties is less understood.

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.

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
