Simple tannin-protein assay to study the diet of Alouatta pigra. Abstract Phenolics, like tannins, are plant-specialized metabolites that play a protective role against herbivory. Tannins can reduce palatability and bind with proteins to reduce digestibility, acting as deterrents to feeding and impacting nutrient extraction by herbivores. Some...

Here we document the modular pattern of development of body systems in Galago moholi, showing that some joints that are critical for specialized leaping and clinging rapidly develop, and tooth crown mineralization proceeds rapidly. However, dental and facial development are delayed in comparison to growth of endocranial volume. Abstract Systems...

An integrated approach incorporating ethnoprimatology, local surveys, direct observations, and fecal DNA analysis, in discovering a novel extended distribution for the banded langur population in Malaysia. Abstract The banded langur (Presbytis femoralis) is a critically endangered primate, restricted to Johor, Malaysia, with an estimated population...

Primate Conservation is a Public Issue Abstract Nonhuman primates (primates) are one of the most endangered mammalian taxa in the world. In the Global North, primates are considered exotic species and, as such, humans' impact on primate conservation and responsibility to protect primates is often ignored. This view differs from the spectrum of...

Genetic characterization of a captive marmoset colony reveals the legacy of admixture and colony management. Abstract The marmoset is a fundamental nonhuman primate model for the study of aging, neurobiology, and many other topics. Genetic management of captive marmoset colonies is complicated by frequent chimerism in the blood and other tissues,...

In the first 6 months of life, colobus infants participate in more nonmaterial handling when they engage in more maternal handling or less nursing. There is no association between nonmaternal handling time and maternal handling or nursing times in older infants. Abstract Primatologists have a long-standing interest in the study of maternal care...
