Impacted Bones: Can Extant Primates Help Identify Tool Use in Early Hominins?

Evolutionary Anthropology: Issues, News, and Reviews, Volume 35, Issue 3, September 2026.
ABSTRACT Despite recent advances pushing back the earliest record of tool use, how and when it first emerged in hominins, and the extent to which it featured amongst the numerous co‐existing species, remain critical questions in paleoanthropology. In addition to analyzing fossils and lithic toolkits, novel strides in understanding this might be made by

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 ...

Cytogentic relations among the genera of the subfamily Pitheciinae (Cebidae, Primates) [PDF]

Caryologia, 2001
Abstract A comparative chromosomal analysis was carried out in some specimens of the three genera of the subfamily Pitheciinae (Pithecia, Chiropotes and Cacajao) using a classic cytogenetic technique (G-banding). The three genera present distinct 2n: Pithecia presents 2n=48, Chiropotes 2n=54 and Cacajao 2n=45 in the males and 2n=46 in the females.

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

Caryologia, 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.

Taxon, Arboreality, Sex, and Season—Factors Influencing Gastrointestinal Parasite Occurrence in Zoo‐Housed Non‐Human Primates

Zoo Biology, Volume 45, Issue 4, Page 371-381, July/August 2026.
ABSTRACT The emergence of anthelminthic resistance is a well‐documented phenomenon in livestock and companion animals. Given the scarcity of new antiparasitic drugs, the implementation of effective, holistic anthelminthic control strategies is critical to preserving the efficacy of existing treatments.

The Case of the Missing Green Iguana Predators: Reviews of Ecological Literature Should Go Beyond Google Scholar

The Bulletin of the Ecological Society of America, Volume 107, Issue 2, April 2026.
Abstract Knowing about species interactions is essential for ecological research, conservation efforts, resource management, and maintaining healthy ecosystems, but many of these, such as reports of predation, may not always be published in easily located resources—if they are published at all.

Phylogenomics of Amazonian squirrel monkeys (Saimiri: Primates, Cebidae)

Molecular Phylogenetics and Evolution
Phylogenetic relationships among squirrel monkeys (genus Saimiri) are still poorly resolved. Morphology-based taxonomies range from two to 12 taxa, while molecular phylogenies have recovered up to 17 different lineages. The last species account lists 11 taxa: Saimiri boliviensis boliviensis, S. boliviensis peruviensis, S. vanzolinii, S.

Forest structure and connectivity drive the functional recovery of seed rain

Journal of Ecology, Volume 114, Issue 2, February 2026.
Local forest structure and landscape‐scale connectivity shape distinct but complementary pathways of the functional recovery of seed rain in tropical forests. Structural complexity promotes functionally diverse plant–frugivore interactions locally, while connectivity facilitates the arrival of late‐successional seeds from external sources.

Neopterin as a Tool for Primate Ecoimmunology: Current Knowledge, Practical Application, and New Directions From Captivity to the Wild

American Journal of Primatology, Volume 87, Issue 10, October 2025.
Neopterin is a sensitive and specific biomarker of intracellular pathogen infection and chronic inflammation, and affected by environmental, life‐history, and sex‐contextual factors. This review offers best‐practice guidelines and practical advice on sample collection, storage, and analysis in primates when used for ecoimmunological conservation and ...

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

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.
