Eco-evolutionary mechanisms underlying critical transitions in microbial communities
Final Report Abstract
Evolutionary adaptation is happening on a short timescale in microscopic organisms like phytoplankton and bacteria, with vast population sizes and rapid generation times of about one division per day. As a result, evolutionary changes can strongly interact with and alter ecological processes, shaping community responses in turn. In this project, I used microbial systems to explore the effects of predation and species interactions on evolution. Additionally, I aimed to highlight the importance of genetic diversity in buffering stress, even across interactions between phytoplankton and their closely associated bacterial communities. Ultimately, my goal is to understand how diversity evolves and influences the resilience of ecosystems under stressful environmental conditions.
