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 ...

Quantifying functionally equivalent species and ecological network dissimilarity with optimal transport distances

open access: yesMethods in Ecology and Evolution, Volume 17, Issue 2, Page 301-321, February 2026.
Abstract Quantifying the structure and dynamics of species interactions in ecological communities is fundamental to studying ecology and evolution. While there are numerous approaches to analysing ecological networks, there is not yet an approach that can (1) quantify dissimilarity in the global structure of ecological networks that range from ...

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

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

An integrated social–ecological–evolutionary–phenotypic (SEEP) approach to understanding animal responses to urbanization

open access: yesBiological Reviews, Volume 101, Issue 1, Page 419-436, February 2026.
ABSTRACT Humans play key roles in shaping the structure and processes of ecosystems globally, especially in cities. This recognition has prompted a recent focus on understanding urban systems via interactions between human social systems and ecological and evolutionary processes.

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 ...

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 ...

Metabolism of sphingolipids by normal and atherosclerotic aorta of squirrel monkeys

open access: yesJournal of Lipid Research, 1970
We studied the synthesis and hydrolysis of sphingomyelin by homogenates of aortic intima plus inner media from normal squirrel monkeys and from monkeys with nutritionally-induced atherosclerosis (6-10 mo on a semi-purified diet containing butter and ...
