Can I Have a Bite? The Influence of Infant Begging on Food Sharing in Capuchin Monkeys (Sapajus Libidinosus). [PDF]

Am J Primatol
Food sharing between mother and offspring in capuchin monkeys is a response to the infant's begging. Infants solicit more frequently high‐quality and hard‐to‐process foods and they are more likely to succeed when they are older and if the food item is not a lizard. ABSTRACT In primates, food sharing from mothers to infants may serve two main functions:

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.

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

Flexible and conservative features of social systems in tufted capuchin monkeys: comparing the socioecology ofSapajus libidinosusandSapajus nigritus [PDF]

American Journal of Primatology, 2011
AbstractSocioecological models assume that primates adapt their social behavior to ecological conditions, and predict that food availability and distribution, predation risk and risk of infanticide by males affect patterns of social organization, social structure and mating system of primates.

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

Monkey Meltdowns: Do Tantrums Influence Maternal Investment in Bearded Capuchin Monkeys? [PDF]

Dev Psychobiol
ABSTRACT Tantrums are widely discussed in human development literature and are typically defined as displays of frustration or anger. In behavioral ecology, they are hypothesized to function as a strategy for securing greater maternal investment. Infant primates often exhibit tantrums when their attempts to obtain maternal care are rejected.

How Food Geometry and Toughness Influence Ingestive Patterns in Lemurs. [PDF]

Am J Primatol
Initial bite placement is influenced by food toughness and geometry. Species‐specific feeding strategies reflect differences in masticatory morphology and functional flexibility. Lemur catta is more likely to use the postcanine tooth row; Propithecus verreauxi prefers anterior biting. ABSTRACT We investigate the extent to which food toughness, geometry,
