Rates of agonism among female primates: a cross-taxon perspective [PDF]

open access: yes, 2013
Agonism is common in group-living animals, shaping dominance relationships and ultimately impacting individual tness. Rates of agonism vary considerably among taxa, however, and explaining this variation has been central in ecological models of female ...

The impact of urbanisation on social behaviour: a comprehensive review

open access: yesBiological Reviews, Volume 101, Issue 2, Page 1003-1035, April 2026.
ABSTRACT Urbanisation is a key driver of global environmental change and presents animals with novel stressors and challenges. It can fundamentally influence social behaviour and has the potential to reshape within‐ and between‐species social interactions. Given the role of social behaviour in reproductive fitness and survival, understanding how social

A perspective on color vision in platyrrhine monkeys [PDF]

open access: yes, 1960
Studies carried out over the past two decades show that many platyrrhine (New World) monkeys have polymorphic color vision. This condition results from the sorting of allelic versions of X-chromosome cone opsin genes at a single gene site, yielding a ...

Presença de Campylobacter spp. em macacos-de-cheiro (Saimiri spp.) assintomáticos cativos e sua correlação com as condições de manejo Campylobacter spp. in asymptomatic captive squirrel monkeys (Saimiri spp.) and its correlation with the handling conditions

open access: yesArquivo Brasileiro de Medicina Veterinária e Zootecnia, 2009
Avaliou-se a circulação de Campylobacter spp. em uma criação de primatas neotropicais macacos-de-cheiro (Saimiri spp.), clinicamente saudáveis, utilizados em investigações biomédicas. A análise foi feita no decorrer de sete anos não consecutivos, de 1995

Prey capture and meat-eating by the wild colobus monkey _Rhinopithecus bieti_ in Yunnan, China [PDF]

open access: yes, 2009
If it is true that extant primates evolved from an insectivorous ancestor, then primate entomophagy would be a primitive trait. Many taxa, however, have undergone a dietary shift from entomophagy to phytophagy, evolving a specialised gut and dentition ...

Investigation of marmoset hybrids (Cebuella pygmaea x Callithrix jacchus) and related Callitrichinae (Platyrrhini) by cross-species chromosome painting and comparative genomic hybridization [PDF]

open access: yes, 2005
We report on the cytogenetics of twin offspring from an interspecies cross in marmosets (Callitrichinae, Platyrrhini), resulting from a pairing between a female Common marmoset (Callithrix jacchus, 2n = 46) and a male Pygmy marmoset (Cebuella pygmaea, 2n

Molecular data highlight hybridization in squirrel monkeys (Saimiri, Cebidae)

open access: yesGenetics and Molecular Biology
Hybridization has been reported increasingly frequently in recent years, fueling the debate on its role in the evolutionary history of species. Some studies have shown that hybridization is very common in captive New World primates, and hybrid offspring ...

Animals as reflexive thinkers: The aponoian paradigm [PDF]

open access: yes, 2017
The ability to engage in reflexive thought—in thought about thought or about other mental states more generally—is regarded as a complex intellectual achievement that is beyond the capacities of most nonhuman animals. To the extent that reflexive thought
