CEES Extra Seminar: Comparative analysis of population divergence along the North Sea-Skagerrak-Baltic Sea salinity gradient

By Carl André, University of Gothenburg, Sweden


Barriers to gene flow between divergent populations result in contact (hybrid) zones. Locations where multiple contact zones overlap can be used in comparative studies asking: what mechanisms maintain barriers; what is the origin of the genetic variation involved; and do differences in life history affect the nature of barriers? Here, I review data from 1. Species divergence across the salinity gradient into the brackish Baltic Sea. 2. The coinciding genetic breaks for several species at the southern tip of Norway.  In addition I present new data on Atlantic cod ecotype distribution in Swedish Skagerrak.

Please note

Carl is visiting us here at IBV/CEES and this seminar will take place in person in the seminar room 3315 Terrarium. There will be no hybrid solution, so please add the event to your agenda. Note that the seminar is NOT on the usual Friday, to reduce the collision with the Kristine Bonnevies lectures Friday morning.
