Anthropic pressures and role of the protists in the regulation of trophic state of mountain lakes

(c) PAPEL – S. Jacob

This project is part of a broader project “Eco-evo dynamics and function of protists in high mountain lakes” led by S. Jacob and D. Legrand (SETE)

Ciliates play major roles in the ecological dynamics of aquatic communities, including the (de-)regulation of trophic state. Their sensitivity to environmental changes and the subsequent consequences for aquatic ecosystems is however poorly understood. In a project coupling quantification of microbial communities dynamics through eDNA in mountain lakes, and experimental approaches in microcosms, we study the sensitivity of ciliate communities to environmental changes, the underlying mechanisms, and the role of these changes for ecosystem functioning.
