Finnish researchers have published the first chromosome-level reference genome of the Saimaa ringed seal, a species that lives isolated in Lake Saimaa. The genetic map makes it possible to study more precisely the population’s diversity and the adaptations it has developed in its freshwater habitat.
The new tool will help scientists and conservation teams monitor genetic risks, such as inbreeding, and plan more effective protection measures. For a small and fragmented population, a better understanding of its genetic heritage is an important step towards maintaining its genetic variation.
