Teaching unit aimed at linking theoretical ecology, its operational implementation, and territorial issues as seen by societal actors. Built on a format combining theoretical courses covering the elements necessary for understanding field issues (ecosystem dynamics, anthropization, socio-ecosystem resilience, in situ conservation, etc.), this teaching unit includes several field blocks (each consisting of a preparatory tutorial/practical and an "active" field trip). The territories visited will provide an opportunity to meet members of society (managers, elected officials, associations, shepherds, etc.) whose position allows us to understand how ecological issues govern their actions and how, in turn, their actions impact biodiversity, its dynamics, and its distribution.

How is biodiversity distributed across the Earth? What ecological, evolutionary, and historical factors determine these patterns of biodiversity distribution? What changes have human activities brought about in the global distribution of biodiversity? In this course, we will study the role of spatial and temporal variations in the environment on a global scale on the dynamics of biodiversity. In particular, we will examine the influence of long-term climate cycles on the past and present diversity of organisms. We will also address the impact of human activities and global changes on biodiversity on a planetary scale.
