Description du projet
Vers des pratiques efficaces de reproduction en captivité pour les primates menacés
Il existe plus de 500 espèces de primates reconnues dans le monde. Près de la moitié d’entre elles sont considérées comme en danger ou en danger critique d’extinction. Un grand nombre de ces primates sont élevés dans des zoos modernes qui servent de lieux de reproduction en captivité, vitaux pour la conservation des primates. L’hapalémur est l’un des 25 primates les plus menacés au monde, et le taux de réussite de sa reproduction en captivité est actuellement peu élevé. Le projet EnPrim, financé par l’UE, lance dans plusieurs zoos une étude qui vise à identifier et à reproduire la signature chimique fertile de la femelle hapalémur, puis à tester ses effets sur la réussite de l’accouplement et le bien-être des populations captives. Le projet entend utiliser des méthodes qui intègrent des techniques inédites de sémiochimie avec des observations comportementales et une endocrinologie fécale établies, ainsi qu’une analyse innovante du microbiote intestinal fécal.
Objectif
Of 504 primate species currently recognized worldwide, almost half are classified as endangered or critically endangered. Captive breeding is vital for primate conservation, with modern zoos serving a crucial role as ambassadors of endangered species, breeders of populations acting as buffers against extinction, and educators of the general public. However, captive populations may experience welfare issues that also undermine their breeding success. Particularly, zoo management is challenging because of the mismatch between natural and captive environments. The aye-aye (Daubentonia madagascariensis) is the only surviving species of the Daubentoniidae, the oldest family of the living lemurs, one of the 25 most endangered primates in the world, and currently showing a low success rate in captive breeding. This multi-zoo project aims to identify and reproduce the female aye-aye’s fertile chemical signature and then test its effects on the breeding success and welfare of three captive troops. We will meet these goals using methods that integrate cutting-edge semiochemistry with established behavioural observations and faecal endocrinology as well as innovative faecal gut microbiota analysis. This novel project will provide findings which should also entail quantifiable impact, such as best practices adopted by target zoos and extended to other institutions through amendments in management policies released by the Studbook Keeper and the Taxon Advisory Group Coordinator for the study species. The complementary expertise of the Fellow and the supervisory team make this project feasible and highly multidisciplinary. The training provided by the supervisor and the host organisation will contribute significantly to the profile of the Fellow, adding new methodological and scientific competences as well as complementary skills which will be imperative for the Fellow’s future career as an independent researcher.
