    Ecologie - Gestion de la biodiversité - Biostatistiques

    Thèmes de recherche

    Mes travaux visent à comprendre les mécanismes qui décrivent et expliquent la sensibilité des espèces à l’hétérogénéité du paysage et aux changements de l'usage des terres dans des environnements sous contraintes anthropiques.

    Les travaux ont pour objectif global de promouvoir les stratégies de gestion de la biodiversité qui concilient les activités humaines et le maintien de la biodiversité sur un territoire. Les espèces étudiées (principalement des vertébrés terrestres) ont un intérêt sociétal fort (services écosystémiques, conflits homme/faune, espèces invasives, dégâts aux cultures, statut de conservation,…). Plusieurs approches méthodologiques sont développées et combinées: 1) observation en milieu naturel (film, piège photo, collier GPS,…), 2) expérimentation (fertilisation, playback, enclo/exclo,…), 3) modélisation statistique et déterministe, 4) approche participative
