Adaptation of natural populations to environmental change: dynamics and interactions
We aim to understand responses of natural populations to natural and human induced environmental change at ecological time scales (i.e. within a few generations). We study ecological and evolutionary responses of individuals and populations to environmental stress (acidification, micropollutants, predation), spatio-temporal dynamics of natural selection, and the molecular mechanisms of adaptation. We are starting work on the role of the host-microbiome interactions in adaptation to global change.
Our research is primarily empirical but with a strong conceptual basis. We are interested in both basic science and applied questions. An important core in our research are interactions between agents of selection (e.g. single vs. multiple stressors; selection vs. gene flow), the quantitative and molecular genetic basis of adaptation (maternal vs. direct genetic effects) and those between ecological and evolutionary processes. We take a whole phenotype perspective, aiming to understand multi-trait adaptation from the physiological mediators to behaviour, morphology and life-history.
Our current main lines of empirical research are:
- Adaptive divergence along environmental stress gradients: evolutionary physiology and genomics of adaptation (amphibians in Sweden) - SNF 2017-2021
- Eco-evolutionary interactions in space and time: ECO-EVO-DEVO (stickleback of lake Myvatn, Iceland) - RANNIS 2019-2022
- Host-microbiome interactions and adaptation to environmental stress (isopods in Switzerland) - Eawag DF 2019-2022
: We use large scale field and laboratory experiments, combined with field surveys, quantitative genetics and genomics, evolutionary physiology as well as proteomics and glycomics.Funding
