MSc. Claire Duchet, Ph.D.

My research interest deals with ecological risk assessment of pollutants with particular emphasis on the effects of multiple stress factors, both anthropogenic (such as a chemical pollution and climate warming) and natural (such as temperature, salinity, and drought) at different biological levels of organization, from the individual to the community.

My research at KBE focuses on the effects of chemical mixtures at environmentally realistic concentrations on the aquatic invertebrate community in a warming environment. Using controlled lab experiments, I measure the effects of mixtures of pesticide and pharmaceutical products combined with increasing temperatures, on the physiology, behavior, and survival of aquatic invertebrates. To assess their effects at the community level, i.e. on the functioning of invertebrate communities and ecosystem processes, I run outdoor mesocosm experiments. Together, these approaches allow a holistic picture on the environmental effects of these anthropogenic disturbers while considering potential climate change effects.
