Sex, genes and speciation - Different chromosomes carrying famous genes determine males and females in common and spiny toads, driving their reproductive barriers. Hybrids, the battle of sex is on! @isyeb.mnhn.fr @molbioevol.bsky.social doi.org/10.1093/molb... www.mnhn.fr/fr/alerte-pr...

Une étude menée par @chrisdufresnes.bsky.social @isyeb.mnhn.fr vient de paraître dans la revue @molbioevol.bsky.social et révèle que ce sont des chromosomes différents qui déterminent le sexe chez le crapaud commun (Bufo bufo) & le crapaud épineux (Bufo spinosus)... 🐸 www.mnhn.fr/fr/alerte-pr...

Thanks to Mathieu Denoël for his massive review work on the invasion pathways of our marsh frogs! Those guys are so invasive that we take them for granted everywhere^^ www.sciencedirect.com/science/arti...

While some biological invasions are well documented globally, others, more cryptic, are often underestimated despite multiple local warnings. This is …

Our study on Duttaphrynus melanostictus evolution published in Nature Communication. We showed how these toads likely spread across the Indian Ocean via human transport, from ancient trade routes to modern shipping. 🌍🐸 @chrisdufresnes.bsky.social @naturecomms.bsky.social @comeniusuni.bsky.social
