The chimpanzee GH locus: composition, organization, and evolution [PDF]

open access: yes, 2012
In most mammals the growth hormone (GH) locus comprises a single gene expressed primarily in the anterior pituitary gland. However, in higher primates multiple duplications of the GH gene gave rise to a complex locus containing several genes.

Copromicroscopic Diagnosis and Prevalence of Intestinal Parasites in Humans and Nonhuman Primates That Share an Ecosystem in the State of Veracruz, Mexico

open access: yesJournal of Parasitology Research, Volume 2026, Issue 1, 2026.
The expansion of human populations and their associated land use practices are contributing to the fragmentation of forest ecosystems, thereby impacting the habitats of wildlife, including nonhuman primates (NHPs). This increased proximity between humans and NHP, which share an ecosystem, creates opportunities for the transmission of gastrointestinal ...

When food fights back: Cebid primate strategies of larval paper wasp predation and the high‐energy yield of high‐risk foraging. [PDF]

open access: yes, 2023
Optimal foraging theory predicts that well-defended potential foods should be exploited only when energy pay-offs are great. Although stinging hymenopteran nests are both well-defended and predated by primates, their larvae's energy yields rarely have ...
