Autopolyploid establishment under gametophytic self-incompatibility: the impact of self-fertilization and pollen limitation Polyploidy is widespread in plants, yet the establishment of neo-polyploids is limited by minority cytotype exclusion (MCE). As polyploidy has been associated with higher selfing rates in empirical st...

The second Ph.D. chapter of Diane's thesis is out as a preprint. She studied the joint evolution of autopolyploidy and self-fertilization under a gametophytic self-incompatibility context.

Feel free to comment, and congratulations, Diane!

Estimating the additive genetic variance for relative fitness from changes in allele frequency Abstract. The rate of adaptation is equal to the additive genetic variance for relative fitness (VA) in the population. Estimating VA typically involves ob

Excited to share my first PhD project with my mentor, @johriparul.bsky.social! We examine how Hill–Robertson interference (HRI) in highly selfing species biases estimates of the distribution of fitness effects of new mutations (DFE).

The New US Sanctions Move Actually Protects Russia For Now Think Four Weeks, Not Two

A new free piece released. The Trump "harsh" sanctions on Russia last night were anything but. They actually provide protection for Russia's biggest oil customers to transact business for at least the next 4 weeks--and have no automatic sanction after that. open.substack.com/pub/phillips...

Hybridization and introgression are major evolutionary processes. Since the 1940s, the prevailing view has been that they shape plants far more than animals. In our new study (www.science.org/doi/10.1126/...
), we find the opposite: animals exchange genes more, and for longer, than plants

Je vois ! Réflexion d’autant plus difficile à intégrer dans des papiers pour ce genre de revue où il faut être court et « impactant » pour être publié 😅

Merci pour vos éclairages !

Étant complètement béotien sur la période et la méthode historique, je serais curieux de savoir quel est le problème avec ce jeu de données et la façon dont il est utilisé dans l’article. Est-ce que cela vient du fait qu’ils n’utilisent que le texte d’un

Parasite-mediated inbreeding depression in wild red deer Heredity - Parasite-mediated inbreeding depression in wild red deer

New paper alert! In my second first-author paper from my work on the Isle of Rum Red Deer Project @rumdeerresearch.bsky.social we show, for only the second time in a wild population, that parasites mediate inbreeding depression.

See you there !

C. elegans is a real animal and we set out to understand how it comes to have its distinctive biogeography. Its ancestral center of diversity is in the higher elevation forests of Hawaii. Its closest relatives are spread across east Asia. Did they travel from Asia? [Preprint 🧵]

Rapid establishment of species barriers in plants compared with that in animals Speciation, the process by which new reproductively isolated species emerge from ancestral populations, results from the gradual accumulation of barriers to gene flow within genomes. To date, the noti...

Check out this cool work from @crouxevo.bsky.social and others, congrats!!! 🥳

I forgot to mention it here, my last PhD chapter (Wolbachia in Culex) is now published in @molbioevol.bsky.social
I think it's a cool study, give it a try 😌
Includes: wPip cid repertoires from all around the world (Nanopore seq. of PCR products), crosses, stability + toxicity tests in cell lines.

I'm very happy to share that our paper describing the evolution of sex chromosomes in brown algae is out!🎉 This project was a long journey, but it came together into a nice story 🧬 🌊 Grateful to everyone who helped along the way!
