Resumo

For the first time, genetic diversity of neutral markers (15 microsatellite loci) was assessed for two species of the landlocked seals: Baikal seal (Pusa sibirica) and Caspian seal (P. caspica) in comparison with the oceanic species of the genus – ringed seal (P. hispida). The study found that both landlocked seals exhibit a reduced level of genetic diversity, with the Baikal seal having the lowest level. Both the Baikal seal and Caspian seal show a high probability of historical bottleneck effect, while the studied population of ringed seals showed no signs of a sharp decline in the past. Analysis of the data using the VarEff package suggests a different time to the most recent common ancestor for each of the three studied populations; for the Baikal seal this time is significantly shorter than for the Caspian seal.
