Article
Human adolescence is characterized by a suite of changes in decision-making and emotional regulation that promote risky and impulsive behavior. Accumulating evidence suggests that behavioral and physiological shifts seen in human adolescence are shared by some primates, yet it is unclear if the same cognitive mechanisms are recruited. We examined d...

Infectious disease is a major concern for both wild and captive primate populations. Primate sanctuaries in Africa provide critical protection to thousands of wild-born, orphan primates confiscated from the bushmeat and pet trades. However, uncertainty about the infectious agents these individuals potentially harbor has important implications for t...

Cognitive flexibility is a core component of executive function, a suite of cognitive capacities that enables individuals to update their behavior in dynamic environments. Human executive functions are proposed to be enhanced compared to other species, but this inference is based primarily on neuroanatomical studies. To address this, we examined th...

Handheld blood analyzers deliver rapid results for biochemical and hematologic parameters, and are very useful to monitor veterinary care. The parameters generated by the point-of-care analyzer iSTAT® Alinity V CHEM8+ cartridge were compared between anesthetized chimpanzees managed where the species naturally resides (range country) and where they...
Article
Chimpanzees ( Pan troglodytes ) are a crucial model for understanding the evolution of human health and longevity. Cardiovascular disease is a major source of mortality during ageing in humans and therefore a key issue for comparative research. Current data indicate that compared to humans, chimpanzees have proatherogenic blood lipid profiles, an i...

Humans are constantly acquiring new information and skills. However, forgetting is also a common phenomenon in our lives. Understanding the lability of memories is critical to appreciate how they are formed as well as forgotten. Here we investigate the lability of chimpanzees’ short-term memories and assess what factors cause forgetting in our clos...

The bushmeat and pet-trade result in unimaginable numbers of primates needing care at in-country sanctuaries.1 Natural social structure was ranked the most important attribute for welfare in chimpanzees under human care,2 but reproduction control is necessary to manage sanctuary populations.3 This study evaluated the reproductive health of sanctuar...

... But as eloquently argued elsewhere [37], this term is conceptually uninformative, given the many ways in which it is applied and assessed. Of these approaches, reversal learning and serial-multiple back-to-back-reversal learning tasks are the most common experimental assays of behavioural flexibility (non-exhaustive examples of each assays in: bees [38,39]; birds [40,41]; fish [42,43]; frogs [44,45]; reptiles [10,46]; primates [47,48]; and rodents [49,50]). We have shown, however, at least for our grackles, faster reversal learning is governed primarily by pronounced reward-payoff sensitivity, so: firstly, these go-to experimental assays do not necessarily measure the unit they claim to measure (a point similarly highlighted in [51]); and secondly, formal models based on the false premise that variation in learning speed relates to variation in behavioural flexibility require reassessment [35,52]. ...
... Leiomyomas have been reported to occur in a wide range of species: human, bongo, rhinoceros, felids, canids, primates, and elephants, among others [16,32,[42][43][44][45]. The literature on neoplasia often does not include the unaffected population, making it difficult to estimate prevalence, but studies that do report these benign lesions show a wide variation in leiomyoma prevalence across mammalian species (Tables 2 and 3). ...
... While the nutritional status of sanctuary apes is far more stable than that of wild apes, most sanctuaries provide a diet that mimics that of wild apes, and apes can also forage within their enclosures (PASA, 2016). In this way, African sanctuary populations show patterns of physiological health and behavior that better mirrors wild populations than do captive populations outside of Africa (Cole et al., 2020;Rosati et al., 2013;. Sanctuary apes also come into direct contact or close proximity to human caretakers daily, and tourists visit many ape sanctuaries as well, providing opportunities for pathogen transmission in both directions (Gilardi et al., 2014;Glasser et al., 2021;Macfie & Williamson, 2010;Schaumburg et al., 2012). ...
