We are particularly happy to see this paper out. It has been in the making for a long time and was a large collaborative effort between postdocs, Phd students, and great colleagues in Gothenburg! @chloehbk.bsky.social @ciarangilchrist.bsky.social

Crosses between divergent-selected lines produced hybrids with reduced gamete viability and striking genome instability (lots more SVs), while parallel-selected lines remained largely compatible. This links ecological selection to the emergence of “intrinsic” genetic barriers.

We evolved yeast for 1000 generations in divergent and in parallel environments. At regular time points during experimental evolution, we made crosses within and between environments, and show that adaptation to different “ecological niches” can generate partial reproductive isolation.

We are looking for candidates with a strong interest in evolutionary biology. Email me if you have any questions about the lab, work, and life in Sweden. Start date in negotiable. Btw, it's perfectly fine to apply if you completed your PhD more than 3 yeas ago!

Thank you Peris and team! I had a fantastic time, you are exceptional hosts!

Small correction: in the graphical abstract, that should be S. paradoxus, not S. cerevisiae! 🫣 🫠
