CHOIX2

How is biodiversity distributed on 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 spatio-temporal variations in the global environment on biodiversity dynamics. In particular, we will examine the influence of long-term climatic cycles on the past and present diversity of organisms. We will also look at the impact of human activities and global change on biodiversity on a planetary scale.

"This module introduces table management and the link between multivariate and univariate: matrix manipulation and common operations; notion of projection and distance; translation of descriptive and univariate statistics with multiple regression/ACP/AFD as an example; indices of (dis)similarity, distance; correlation".

The objectives of this EU are twofold. On the one hand, the aim is to review all the major stages in the history of organisms on Earth since its birth. Topics such as the appearance of life, the colonization of continents, the appearance of angiosperms, glacial/interglacial cycles and the domestication of plants will be covered. On the other hand, the aim is to show how paleoecology is part of the modern world, whether in terms of methodological developments (geochemistry, optical, electron and X-ray microscopy, etc.), predictive models for climate change, ecosystem management in the context of global change, or biotechnological developments. The course will be organized as a series of lectures, each given by a specialist in the subject concerned.
