Bernard Kaufmann



B. Kaufmann is a lecturer in biology at the University Claude Bernard Lyon and a member of the laboratory of ecology of natural and anthropized hydrosystems since 2001. He is interested in the global changes of the Anthropocene affecting biodiversity, such as urbanization, biological invasions, fragmentation of territories and climate change. He studies these changes using two approaches, that of the urban landscape and its transformations, and that of the study of the biological communities that respond to them. For the first approach, he works with geographers and computer scientists, as well as with local authorities and associations, in order to provide a spatial and temporal understanding of the place of biodiversity in the urban world, particularly in the Lyon metropolis, his model landscape. For the second, still in plurality, he seeks to document how urbanization, climate and biological invasions influence biological communities, the dispersal of individuals and gene flow within and between species. He uses methodologies from geography (remote sensing, spatial analyses), computer science (invasion modeling), field ecology, and population genetics. Among his biological models of study, ants, on which he has been working since 1989, occupy a major place. He has an active role in the LabEX IMU (intelligence of urban worlds), as member of the steering comittee. He teaches zoology and ecology at the bachelor's and master's levels. He is the head of the Master's programme "Ecology of the Anthropocene: urbanization, biodiversity, water".
