CICASP student Rafaela Takeshita and her collaborators from the department of Ecology and Social Behavior at KUPRI and the Zoology Department at Okayama University of Science have just discovered that neonatal Japanese macaques have extremely high levels of dehydroepiandrosterone-sulfate (DHEAS), a sex steroid precursor secreted by the adrenal gland. Their findings will appear shortly in the journal General and Comparative Endocrinology .
A new study published in the American Journal of Primatology (Vol. 75(7), pp. 774-787) shows that ovulation in olive baboons ( Papio anubis ) is advertised through a complex set of sexual signals and cues displayed in several modalities.
Two new articles reveal that giraffe have more in common with nonhuman primates than often assumed.

A new study published in the journal Scientific Reports uses well-controlled experiments on our closest relatives, the chimpanzees, to highlight important implications concerning how we humans develop our face perception system.
A new study published in the journal PLoS ONE has shown that infection by parasitic nematodes may be facilitated by social contact between primate group members ( click here for the original article ).
