Research Group Biodiversity
Overview
The research group Biodiversity aims to understand the regulation of biodiversity and its consequences for ecosystem functioning. We investigate how environmental change alters competitive and trophic interactions among coexisting species and genotypes, and how this affects ecosystem functioning. Our experimental model systems comprise phytoplankton and benthic macro- and microalgae including their associated consumers and bacteria. Using trait-based approaches, we investigate the direct and indirect effects of climate change in near natural communities and/ or over longer time scales capturing multiple generations in microcosms. A key question addresses how eco-evolutionary coupling contributes to the functioning of phytoplankton communities. One of our future endeavours is to understand density dependence for the form of symbiosis between phytoplankton and their associated bacteria and the consequences for community dynamics. Another is the potential applicability of diverse microalgae as food for life stock breeding and aquaculture.
