Lab meeting: 21 April 2010 at 10:15am, Darwin room

Good morning everybody,

We will have a lab meeting this week. Two things are on the agenda:
1) Fabrice has been invited to give a seminar in Linköping and would like to get your feedback on his presentation. He will speak about

Joint effects of migration modification and assortative mating in the early stages of ecological speciation

Fabrice Eroukhmanoff, Anders Hargeby & Erik I. Svensson

ABSTRACT: The question of how diverging populations might become separate species by restraining gene flow is a central issue in evolutionary biology. Assortative mating might emerge early during divergence, but migration modification can also play an important role in speciation. We demonstrate that two recently diverged ecotypes of a freshwater isopod have rapidly developed pre-mating isolation. This is consistent with ecological speciation theory, which predicts that sexual isolation arises as a byproduct of ecological divergence. However, migration modification acts as the main barrier to gene flow, although the joint emergence of these two isolating mechanisms has facilitated adaptive divergence. These results underscore that migration modification might be as important as assortative mating in the early stages of ecological speciation.

2) Tina would like to get your input on some 'work in progress'. Please email me under Maren.wellenreuther@zooekol.lu.se to get the attachments - if you have not received them already.

Any fika volunteers for this week? See you all on Wednesday, Maren

Lab-meeting on population divergence in isopods and lizards

This coming Wednesday (30 September), we will discuss one manuscript by Fabrice, Anders Hargeby and me on sexual isolation and migration modification in the aquatic isopod (Asellus aquaticus) and another one by Anna, Bengt and me on colour polymorphism divergence and population genetics in Podarcis-lizards. We would like to have the input from as many as possible on these two interesting manuscripts (at least we think they are interesting, but as authors we are of course highly biased!).

We will start with the lizard manuscript at 10.00, and continue with the isopod manuscript after that. I will send out these manuscripts by e-mail to the whole group today (Monday) provided that Anna and Fabrice send me the updated last versions first. If you do not get it by e-mail, please e-mail Anna (anna.runemark@zooekol.lu.se) and Fabrice (fabrice.eroukhmanoff@zooekol.lu.se) so that they can send you the manuscripts.

Time and place as usual: "Darwin" at 10.00 on September 30 (Wednesday). Any fika volunteer?
