The Biodiversity Ecology and Evolution degree at the Université Paris-Saclay covers a wide range of disciplines concerning the management and understanding of biodiversity in relation to the environment. The BEE program consists of a Master's degree (M1) that allows students to acquire all the fundamentals of ecology/evolution, using approaches that include field observations, laboratory analyses, and modeling. The M1 program leads to six Master's degrees (M2) allowing students to specialize in a specific area of ecology. • Conservation Ecology, Ecological Engineering: Research and Expertise (ECIRE) • Evolutionary and Functional Ecology (EVEF) • Landscape Ecological Approach (AEP) (apprenticeship) • Chemical Pollution and Environmental Management (PCGE) • Higher Education Training in Life Sciences (Preparation for the SV-STU agrégation) (Preparatory Agregation) • Evolution of Genomes, Populations, and Species: Data and Models (EVOGEM) At the same time, some students may choose to pursue a Magistere which will allow them to obtain a dual degree at the end of the Master's degree: a Master's degree in BEE and a Magistere in Biology.
