Dispersal, local adaptation and introgression in Atlantic salmon populations |
|
Research
The Atlantic salmon is a species renowned for the return of spawning fish to their native rivers following their migration at sea. However, some individuals disperse to nearby rivers, leading to a local metapopulation functioning, and sometimes they also travel to more distant rivers. Theoretically, these dispersal events have a significant impact on population demography, local adaptation, and resilience to climate change. To test these hypotheses, this project has three objectives: i) to measure fine-scale dispersal within and between salmon metapopulations in France, ii) to identify the genes or genomic regions under selection and involved in the local adaptation of populations, and iii) to infer adaptive genetic introgressions resulting from dispersal or restocking. This project is based on the genotyping of 1,500 salmon using a 60,000-SNP chip and is being carried out in collaboration with the ECOBIOP and CBGP units.
