Le mardi 29 novembre 2022, Olivier KAISIN présentera l'examen en vue de l’obtention du grade académique de Docteur en Sciences (Collège de doctorat en Biologie des organismes et écologie) sous la direction de Pascal PONCIN, Fany BROTCORNE et Laurence CULOT (Co-tutelle avec l’Universidade Estadual Paulista).

Cette épreuve consistera en la défense publique d’une dissertation intitulée :

« Stressed out primates? Physiological and behavioural responses of primates to habitat disturbances: A focus on Black Lion Tamarin (Leontopithecus chrysopygus) in the Brazilian Atlantic Forest  ».

Abstract

Fuelled by exponential human population growth and the unsustainable exploitation of Earth’s resources, forests continue to disappear at alarming rates and human pressure on ecosystems keeps intensifying. Along with most large-bodied mammals in the tropics, non-human primate populations suffer the consequences of habitat loss, degradation, and fragmentation. Thus, evaluating and understanding the effect of anthropogenic disturbances on primate populations is paramount for their conservation. In this context, measuring glucocorticoid (GC) concentrations is a powerful tool to assess animals’ welfare, giving precious insight on their behaviour, physiology, and ecology. To improve current knowledge of how primates cope in changing environments, in this thesis we explored GC variations at a global scale before focusing on an endangered neotropical primate, the black lion tamarin (Leontopithecus chrysopygus), at a regional and local scale.
