Do we really understand how complex systems evolve? Based on experimental evolution in stable vs fluctuating temperature conditions, we show that adaptive mutations in the fungus Zymoseptoria tritici are (i) massively pleiotropic, and (ii) opposed to the phenotypic plasticity.

Graphical summary of the experimental evolution protocol. Strains of the fungus Zymoseptoria tritici were raised in stable cool, stable warm, or fluctuating temperature conditions for ~ 250 generations, with 2 initial genotypes are three evolutionary replicates. The transcriptome was sequenced before and after evolution at both temperatures. Illustration of the unexpected response of gene expression plasticity to the evolutionary treatment. Plasticity (i.e. the difference in expression between 23°C and 17°C) evolved more in stable conditions than in fluctuating conditions. Contergradient plasticity: gene expression in stable conditions evolved in a direction opposite to the initial plasticity, as if plasticity in the initial strains was maladaptive.

We were all very sad to learn the death of Pierre Capy. Pierre was a professor at University Paris Saclay, in the 1990s, he started a group working on the evolutionary genomics of transposable elements; this group is still very active today. He was a great teacher, mentor, and colleague.

Pierre Capy était un généticien, un drosophiliste, un acteur majeur dans l'essor de la génétique des éléments transposables en France. Très impliqué dans l'administration de la vie scientifique, il a aussi été directeur du laboratoire LEGS (actuel @EGCE), et un des fondateurs en 2016 de @IDEEV.

Happy to hare that the preprint I was advertising below has been published by the Journal of Evolutionary Biology: academic.oup.com/jeb/advance-... Thanks @jevbio.bsky.social for supporting responsible publishing!

Time to publish responsibly: DAFNEE, a database of academia-friendly journals in ecology and evolutionary biology

Abstract. The current economics of scientific publishing reveal a profound imbalance: academia pays prices far exceeding the actual costs of publication. R

Very proud to see this work highlighted by the journal! Publishing in Evolution has always meant something special to me. Congrats to the first author Sylvain Pouzet who found the energy to keep on working on his master project during his PhD.

Very glad to see the second chapter of my PhD published in JEB and feel honored that it has been picked as this month's issue "Editor's choice" and cover image! It's been a long and important team effort leading up to these results!

Wow. This is sooo good. Echoing @urbanevol.bsky.social this user’s manual for Ne should be required reading for popgen and conservation genetics folks. onlinelibrary.wiley.com/doi/10.1111/...

The Idiot's Guide to Effective Population Size

This is a reference manual for the elegant, yet hideously complex concept of effective population size (Ne), inspired by a classic, self-published manual of automotive repair ‘for the compleat idiot’...

SpringerNature keeps on creating new outlet after new outlet... Seems like nothing can stop them. Just like that joke of a guy putting coins into the soda vending machine: "So long as I'm winning, I'm playing"... But who pays? We researchers are the fools and we seem to like it.
