Primatas e suas particularidades evolutivas reveladas através de duas distintas abordagens genéticas [PDF]
A ordem Primata (Primates) compreende dois clados maiores que divergiram há aproximadamente 87 Ma: Strepsirrhini e Haplorrhini. Dentre os Haplorrhini, Platyrrhini é o único clado cujas espécies habitam o continente Americano, enquanto os Catarrhini ...

The effects of feeding frequency on jaw loading in two lemur species
Abstract Objectives Studies on oral processing are often snapshots of behaviors that examine feeding through individual bouts. In this study, we expand on our previous work comparing bite/chew variables per feeding bout to summed daily biting, chewing, and food intake to interpret loading that could have potential morphological effects.

Male‐biased stone tool use by wild white‐faced capuchins (Cebus capucinus imitator)
Map of study site showing the islands of Coiba and Jicarón in Coiba National Park, Panama. On Coiba, both sexes of adult white‐faced capuchins use stone tools, while on Jicarón only males have been observed to use tools. Abstract Tool‐using primates often show sex differences in both the frequency and efficiency of tool use.

Long-Term Spatial Memory and Learning Set Formation in Captive Capuchin Monkeys (Cebus libidinosus = Sapajus cay) [PDF]
Researchers have long suspected that nonhuman primates have long-term spatial memory for locating food. However, few empirical studies have assessed spatial memory for a period longer than 1 day in nonhuman primates in a foraging context.We used a ...

Utilização de técnicas de Enriquecimento Ambiental para promoção do bem-estar de dois espécimes de Sapajus libidinosus (Primates, Cebidae) no Zoológico Municipal de Uberlândia, Uberlândia, MG. [PDF]
Providing welfare is a challenge for institutions that keep animals under human care, as they are more likely to experience a low level of welfare. Environmental enrichment techniques can be adopted in order to maintain a better quality environment ...

Material matters: raw material influences stone tool performance in capuchin monkeys [PDF]
Identifying the conditions that facilitate and shape tool use is a central focus in the field of human evolution and animal behaviour. Particular interest lies in the use of stone hammers by nonhuman primates to open encased food sources.
