American 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.

Chromosome phylogeny of the subfamily Pitheciinae (Platyrrhini, Primates) by classic cytogenetics and chromosome painting [PDF]
, 2010 Background: The New World monkey (Platyrrhini) subfamily Pitheciinae is represented by the genera Pithecia, Chiropotes and Cacajao. In this work we studied the karyotypes of Pithecia irrorata (2n = 48) and Cacajao calvus rubicundus (2n = 45 in males and ...

Zoo 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 ...

Male Reproductive Strategies in Black and Gold Howler Monkeys (Alouatta caraya) [PDF]
, 2013 Behavioral and demographic factors such as group size, social structure, dispersal patterns, and mating systems affect male reproductive success. In the present study, we analyze the relationship between social structure, genetic relatedness of adult ...

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

Journal 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.

The complete mitochondrial genome sequence of the black-capped capuchin (Cebus apella)
Genetics and Molecular Biology, 2012 The phylogenetic relationships of primates have been extensively investigated, but key issues remain unresolved. Complete mitochondrial genome (mitogenome) data have many advantages in phylogenetic analyses, but such data are available for only 46 ...
