Risk perception – or an individual's susceptibility to perceive a threat (e.g. disease, predator, competitor) – has shaped the physiology, cognition, behavior and ecology of animals for millions of years. While a lot of research has focused on lethal threats (i.e. predation), only recently have we increased our understanding of how animals, and more particularly […]

Wild orangutans inhabit extremely variable dietary environments with fluctuations in fruit availability that cause significant changes in their dietary compositions and total caloric intake. Many studies on mammals and primates show clear signals of seasonal variation in gut microbiota. A few primate studies demonstrate that gut microbiota may be helping hosts maintain energy balance during […]

Résumé: L'écologie évolutive de la santé des femmes : une approche bioculturelle Être une femme est-il une maladie ? Cette question provocatrice souligne la pathologisation traditionnelle de la fonction reproductive féminine dans la biomédecine occidentale depuis le 19e siècle. Récemment, les sciences sociales ont lancé un appel pour dépasser les recherches sur le 'bikini', c'est-à-dire […]

Understanding and predicting human cooperative behavior and beliefs dynamics remain a major challenge both from the scientific and practical perspectives. Because of the complexity and multiplicity of material, social and cognitive factors involved both empirical and theoretical work tend to focus only on some snippets of the puzzle. Recently, a mathematical theory has been proposed […]

In primates and other mammals, male care for immatures is generally restricted to species that form enduring pair bonds or breed cooperatively. However, a growing body of evidence suggests that there are alternate paths to the evolution of male care in nonhuman primate species. Natural selection has favored the evolution of some forms of male […]
