The First Capitular Joint in Primates: Cebidae, Cercopithecidae and Homo

open access: yesOkajimas Folia Anatomica Japonica, 1992
As for the first capitular joint, Ohman (1986) claimed that a univertebral type is unique to modern and fossil hominids among primates. Stern and Jungers (1990) compiled the data in a wider range of primate and demonstrated as follows. The univertebral type, rather than being unique to hominids, is common among siamang, occurs in an occasional gibbon ...

Object grasping and manipulation in capuchin monkeys (genera Cebus and Sapajus) [PDF]

open access: yes, 2018
The abilities to perform skilled hand movements and to manipulate objects dexterously are landmarks in the evolution of primates. The study of how primates use their hands to grasp and manipulate objects in accordance with their needs sheds light on how ...

Absence of Blood Chimerism in Twin Goeldi's Monkeys (Callimico goeldii): Implications for Interpreting Callitrichid Phylogeny

open access: yesAmerican Journal of Primatology, Volume 87, Issue 9, September 2025.
All Callitrichidae have twins who are chimeras, but Callimico has singletons. We examined evidence of blood chimerism in the only known surviving Callimico twins, and found that they were non‐chimeric. This represents the first report of the absence of blood chimerism in twins of any callitrichid species.

Centromeric enrichment of LINE-1 retrotraposon in two species of South American monkeys Alouatta belzebul and Ateles nancymae (Platyrrhini, Primates)

open access: yesCaryologia, 2022
LINE-1 are retrotransposable elements, a kind of repetitive DNA included in the heterochromatin regions of chromosomes. Repetitive DNA represent one of the major genomic components which role is not still clear challenging genomic assembly.

Sistemática, evolución y paleobiogeografía de los primates Platyrrhini [PDF]

open access: yes, 2013
Estudios recientes acerca de las relaciones filogenéticas entre los primates platirrinos basados en datos morfológicos y moleculares, concuerdan en una división en tres familias: Atelidae, Pitheciidae y Cebidae, con la única excepción de Aotus, que ...

Kunsia tomentosus (Rodentia: Cricetidae) [PDF]

open access: yes, 2016
Kunsia tomentosus (Lichtenstein, 1830), the woolly giant rat, is a semifossorial cricetid typically associated with the Cerrado and Beni domains in central South America. Kunsia was recently revised and includes only 1 species.

Wild Encounters: Analyzing Human–Animal Interactions in British and Irish Association of Zoos and Aquariums Facilities

open access: yesZoo Biology, Volume 44, Issue 5, Page 461-473, September/October 2025.
We investigated the quantity and diversity of animal–visitor interactions in BIAZA‐accredited facilities, finding 740 opportunities for interactions across a range of contexts including walkthroughs and handling. Meet and greets were the most offered and were influenced by the number of individual animals, cost of interaction, and animal popularity ...

Morphofunctional Space of the Forelimb in Caraguatypotherium munozi (Notoungulata; Mesotheriidae): Insights Into Wrist‐Powered Digging

open access: yesJournal of Morphology, Volume 286, Issue 8, August 2025.
Caraguatypotherium munozi displays a distinctive morphofunctional configuration combining high wrist flexor leverage with reduced elbow mechanical advantage—traits consistent with wrist‐dominated scratch‐digging. Multivariate analyses place it outside the core morphospaces of extant locomotor groups.

Amplification Dynamics of Platy-1 Retrotransposons in the Cebidae Platyrrhine Lineage

open access: yesGenome Biology and Evolution, 2019
Platy-1 elements are Platyrrhine-specific, short interspersed elements originally discovered in the Callithrix jacchus (common marmoset) genome. To date, only the marmoset genome has been analyzed for Platy-1 repeat content. Here, we report full-length Platy-1 insertions in other New World monkey (NWM) genomes (Saimiri boliviensis, squirrel monkey ...
