Sampling, modelling and prediction for freshwater species across river ecosystemsan example with the freshwater pearl mussel Margaritifera margaritifera (L., 1758)

Résumé

There is a general need to provide integrative studies to understand, retain and simplify the information contained in spatial patterns of biodiversity in complex ecosystems such as rivers. The general objectives of this thesis are to implement a complete process of sampling, modelling and predicting for freshwater species across and within river networks focused on biotic interactions. To address this objective the endangered freshwater mussel Margaritifera margaritifera (L., 1758) that must pass its larval stage attached to a host fish, is used to gain biological and ecological knowledge to manage its conservation.
