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...
The alien marsh frog cocktail: Distribution, causes and pathways of a global amphibian invasion
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
The long-awaited book "Status of Decline and Conservation of Amphibians of the Middle East" has just been released! Happy to have helped out for one chapter on Syrian amphibians by Ahmad Aidek, Mudar Salimeh, Yaman Omran and Daniel Jablonski link.springer.com/chapter/10.1...
The Composition, Distribution, and Endangerment of the Amphibian Fauna of Syria
Syria has a broad range of natural landscapes, including mountains, forests, rivers, lakes, and arid landscapes that promoted the diversification of its amphibian fauna. Syrian amphibians presently co...
