CHOICES3

This teaching unit aims to link theoretical ecology, its operational implementation and the issues of territories as seen by society's actors. Built on a format combining theoretical courses recalling the elements necessary for the understanding of field issues (ecosystem dynamics, anthropization, resilience of socio-ecosystems, in situ conservation, etc.), this UE includes several field blocks (each consisting of a preparatory TD/TP and an "active" field trip). The territories visited will allow the students to meet actors from society (managers, elected officials, associations, shepherds, etc.) whose position allows them to understand how ecological issues govern their actions, and how in return their actions impact biodiversity, its dynamics and its distribution.

How is biodiversity distributed on Earth? What ecological, evolutionary and historical factors determine these patterns of biodiversity distribution? What are the changes induced by human activities on the global distribution of biodiversity? In this course, we will study the role of spatio-temporal variations in the global environment 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 at the planetary scale.
