Manage episode 498244841 series 1451457
The postglacial history of the Saimaa ringed seal
Science Sessions are brief conversations with cutting-edge researchers, National Academy members, and policymakers as they discuss topics relevant to today's scientific community. Learn the behind-the-scenes story of work published in the Proceedings of the National Academy of Sciences (PNAS), plus a broad range of scientific news about discoveries that affect the world around us.
In this episode, Jaakko Pohjoismäki, Jukka Jernvall, and Ari Löytynoja discuss the evolutionary history of the Saimaa ringed seal.
In this episode, we cover: •[00:00] Introduction •[01:06] Molecular biologist Jaakko Pohjoismäki introduces Lake Saimaa and the Saimaa ringed seal. •[02:30] Zoologist Jukka Jernvall talks about the characteristics of species isolated by glaciation. •[03:27] Evolutionary biologist and bioinformatician Ari Löytynoja explains the genetic and demographic methods of the study. •[04:11] Löytynoja and Jernvall explain why the results were surprising and where the study turned next. •[06:20] Pohjoismäki and Löytynoja describe the study’s implications for biodiversity in postglacial habitats. •[07:50] Jernvall and Löytynoja talk about the study’s caveats and limitations. •[10:14] Conclusion.
