Gwendoline M. David

Dr. Gwendoline M. David serves as a Research Fellow in the Department of Plankton and Microbial Ecology at the Leibniz Institute of Freshwater Ecology and Inland Fisheries (IGB Berlin), where she investigates microbial community responses to anthropogenic stressors in freshwater ecosystems through experimental and meta-analytical approaches.

Her research program centers on:

• Microbial decomposition processes in riverine systems
• Impacts of salinization and thermal stress on community dynamics
• Benthic-pelagic interactions in stream ecosystems
• Urban stream restoration ecology
• Molecular techniques for microbial functional analysis
• Global change effects on freshwater biodiversity

Recent publications reveal a pronounced focus on multi-stressor interactions, particularly examining how salinization and warming synergistically alter microbial decomposer communities and organic matter processing. Her work integrates field mesocosm experiments, meta-analyses of global datasets, and advanced molecular methods to quantify ecosystem vulnerability, with consistent findings demonstrating reduced decomposition rates and altered community structures under combined stressors.

Within IGB Berlin's collaborative research environment, Dr. David contributes to departmental initiatives addressing freshwater ecosystem resilience. While specific advising roles and grant details remain undocumented in available materials, her extensive co-authorship across interdisciplinary projects indicates active participation in large-scale research networks focused on anthropogenic impacts in aquatic systems.
