dc.description.abstract
Genetic diversity is the raw material of evolution and allows species and populations to adapt and persist in changing environments. Systematic and representative monitoring of genetic diversity has rarely been conducted, resulting in under-reporting to national and international authorities. Following our 2020 feasibility study on how genetic diversity and possible changes over time could be assessed across a variety of organisms, we initiated a pilot study for monitoring genetic diversity in five species across Switzerland. The pilot study aims to gain experience on how to implement a genetic diversity monitoring program using genomic approaches. We have selected five candidate species, each of which occurs in a specific habitat type of national importance and/or in anthropogenically modified landscapes. For each of the five species, we de novo assembled a reference genome. In 2021, we sampled >1,100 individuals from 135 populations across all biogeographic regions in Switzerland, applying a proportionally stratified random sampling strategy. We are currently whole-genome re-sequencing all individuals (~10x coverage). To explore possible changes in genetic diversity over time, we started a retrospective analysis of genetic diversity in two species, using specimens from natural history collections dating back up to 218 years. First results indicate that contemporary samples well represent the climate-space of each study species in Switzerland, and that retrospective monitoring based on historic DNA is feasible, but challenging. Another challenge remains to develop meaningful and intuitive indicators of change in genetic diversity for reporting to national and/or international authorities as well as practitioners.
