EVOLUTIONARY RESCUE AND ADAPTIVE REVERSALS IN HISTORICALLY ACIDIFIED LAKES

We applied whole genome sequencing to zooplankton resting eggs extracted from sediment cores to address the potential for evolutionary rescue in zooplankton populations to lake acidification and pH recovery in Killarney (Ontario) lakes. By employing temporal genomic data and resurrection ecology experiments in lake ecosystems that have been impacted by historical human disturbance, our research fills a critical knowledge gap about the long-term implications of evolutionary rescue in the wild.
