Thèmes de Recherche :

Monitoring in past environment using foraminifera and thecamoebian indicators addresses one of the fundamental problems for environmental assessment – how to characterize the state of benthic environments in regard to both contemporary and historical times. Foraminifera and thecamoebian facilitate biological characterization of a variety of freshwater and coastal marine environments; they react quickly to environmental stress, either natural anthropogenic. Because of their small size, they occur in large numbers in small samples (e.g., cores) and since they have shell, they yield fossil assemblages that can used as proxies to reconstruct past environmental conditions. My research objective is to describe foraminifera and thecamoebian relative to their Present environment in order to reconstruct past environments
