Occurrence of Antibodies Anti‐Toxoplasma gondii in Captive Non‐Human Primates From Pernambuco State, Brazil

Journal of Medical Primatology, Volume 55, Issue 4, August 2026.
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.

Structural Diversity of the Extensor Digitorum Profundus Muscle Complex in Platyrrhini [PDF]

Folia Primatologica, 2017
Separate extension of fingers in the hand of primates is performed by 3 muscles: m. extensor pollicis longus, m. extensor digiti secundi, and m. extensor digitorum lateralis. Here it is proposed to consider them as parts of the extensor digitorum profundus muscular complex.

Guidelines and considerations for capturing and collaring wild primates: a case study with capuchin monkeys (Sapajus nigritus cucullatus) [PDF]

Anais da Academia Brasileira de Ciências
Many aspects of the ecology, evolution and social behavior of wild-living primates remain un-explored and require further investigation. While long-term field studies are crucial for addressing conservation concerns for many primates’ species, acquiring ...

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

Developmental Psychobiology, Volume 68, Issue 3, May 2026.
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.

Pairing and recombination features during meiosis in Cebus paraguayanus (Primates: Platyrrhini)

BMC Genetics, 2009
Background Among neotropical Primates, the Cai monkey Cebus paraguayanus (CPA) presents long, conserved chromosome syntenies with the human karyotype (HSA) as well as numerous C+ blocks in different chromosome pairs. In this study, immunofluorescence (IF)

But how does it smell? An investigation of olfactory bulb size among living and fossil primates and other euarchontoglirans

The Anatomical Record, Volume 309, Issue 4, Page 1037-1060, April 2026.
Analysis of cranial endocast data of 181 extant and 41 fossil species from Euarchontoglires shows that there was a reduction in olfactory bulb size in Crown Primates, but that there were also subsequent reductions in various other primate clades (Anthropoidea, Catarrhini, Platyrrhini, crown Cercopithecoidea, Hominoidea).

Molecular studies of Callithrix pygmaea (Primates, Platyrrhini) based on transferrin intronic and ND1 regions: implications for taxonomy and conservation

Genetics and Molecular Biology, 2000
Traditional classifications of Platyrrhini monkeys, based mainly on morphological features, are being contested by recent molecular data. The subfamily Callitrichinae (Platyrrhini, Primates) consists of a diverse group of species, many of them considered

PriMath—The Role of Intrinsic Factors in Quantitative Cognitive Performance of Highly Social Primates

Ecology and Evolution, Volume 16, Issue 4, April 2026.
Our study investigated the quantity discrimination ability in a highly social group of New World monkeys, with the goal of understanding how individual differences in performance due to group composition might be explained from an evolutionary perspective.
