Balanus improvisus - Carl André
Barnacles are adapted to a varying environment by being physiologically plastic. Plasticity may infer costs. Balanus improvisus in the only barnacle species inhabiting the the Baltic sea, where the salinity is low but stable. Question: have barnacles at the extreme of the environmental gradient traded some of their plasticity against a genetically fixed narrow tolerance range.

Deabryomyces hansenii - Anders Blomberg
Debaryomyces hansenii is a highly salt tolerant marine yeast species that can grow and survive in close to saturated NaCl solutions (≈25%). It features a highly efficient set of mechanisms for osmoregulation, in particular efficient efflux pumps for sodium and influx pumps for the osmolyte glycerol.

Q: Can these efficient osmoregulatory systems have evolved solely in order to cope with the mediocre salinity of the sea (≈3%), or are they a consequence of combined selection pressures, e.g. under scarce availability of good carbon sources?
>> To the CeMEB Discussion Forum

Idotea baltica - Susanne Eriksson
Studying selection in Idotea baltica has practical restrictions in the numbers of replicate populations and tanks possible. How can we best design this experiment to maximize our results with ideally just 2 Baltic and 2 fully marine populations and salinity as the selection pressure?

10.45 - 11.30 - Session 2, Big lecture hall

Speed discussions- chairing Anders Blomberg

Littorina saxatilis - Kerstin Johannesson
Evolution of a paraphyletic species. What population genetic signatures or phylogenetic signatures will be observed in the genome if there is both weak gene flow over ecotype hybrid zones (A) and a similarly weak gene flow between populations of similar ecotype (B)? But, gene flow between ecotypes will be under strong divergent selection while gene flow within ecotype will only be affected by drift (due to similar selection pressures).

Following up question: for which relationship between A and B will such a system like this result in speciation, and for what relationships will the system remain a polymorphic species? (Both A and B should be small, <10/generation, and populations sizes large – if of any importance)
>> To the CeMEB Discussion Forum

Apmhiura filiformis - Sam Dupont
Evolution of regeneration: how does regeneration potential relate to energy trade-offs in brittlestars? There is a lot of variability between species in the ability to regenerate lost limbs. What makes Amphiura filiformis a champion within the brittlestars?

15.00 - 15.45 - Coffee & tea

15.45 - 16.45 - Session 4 - Big lecture hall

Speed discussions - chairing Per Jonsson

Fucus radicans - Kerstin Johannesson
How will a superclone affect the potential for evolution?
>> To the CeMEB Discussion Forum

Pomatochistus minutus - Lotta Kvarnemo
Our sand gobies at the Swedish west coast stop breeding around midsummer. — Why don't they continue into later in the summer or fall, like common gobies do?
>> To the CeMEB Discussion Forum

Skeletonema marinoi - Anna Godhe
The planktonic diatom Skeletonema reproduces mainly asexually, with occasional sexual reproduction. If we know allele frequencies from subsamples collected with even intervals during two years and we can estimate N, can we come to know the frequency of sexual reproduction?
