Congratulations!🎉

📢 Adoption of new IUCN resolution on #amphibian #conservation 📢 🐸
Big news, since a recent study showed that amphib conservation is serially underfunded. The TLDR of this are calls for:
-updated conservation guidelines
-govts to implement long term national plans
-funding research

In biblical times, frogs were seen as a plague

Today, thanks to new research, we know they’re actually guardians against disease 1/5

Just gave my talk at @austevolsoc.bsky.social 🐸
Shared our work on polyploidy and sex chromosome evolution in Australian burrowing frogs Neobatrachus.
Exciting discussions on autopolyploids vs allopolyploids and their inheritance patterns!

Off to AES 2025 in Brisbane to talk Neobatrachus! Records suggest both tetraploids can show up in Queensland. After three years with their specimens in Germany, the idea of seeing them in person feels a bit like meeting long-distance friends IRL 🐸 #Neobatrachus #amphibian #museomics

Been through this course, great content and very practical. Strongly recommend

HiFi assemblies from museum samples

Honored to present our latest progress on using museomics to study the Australian burrowing frogs Neobatrachus at the 23rd European Congress of Herpetology. Also very happy to have met so many new friends during these five days! #SEH2025

Today, besides my family, my supervisor sent me wishes. It may seem like a small gesture, but it carries a lot of warmth when you are far far from home. Moments like this remind me that a good PhD is not only about research, but also about mentorship, kindness, and growing together #birthday

Polyploid Formation Through Disrupting Mitotic Sister Chromatid Separation of Spermatogonia based on espl1 Heterozygous Knockout in Fish Abstract. Polyploidy is a major driver of speciation and evolutionary changes in plants and animals. Production of unreduced gametes is considered as a mai

Zhang et al. generated a heterozygous espl1 knockout line in diploid loach, showing that the heterozygous loss of espl1 was enough to induce spermatogonial mitotic sister chromatid separation defects, causing the production of unreduced sperms.

The poster features 176 species of frog from Madagascar, to scale. The biggest species are over 100 mm, the smallest are under 10 mm. They come in all kinds of shapes and sizes and colours. So many variations on the theme of frog!

Thrilled to announce version 2.0 of my poster featuring some of Madagascar's endemic frog species, to scale! This version features 176 species—40 more than version 1.1 (now retired)! Check it out!

Many amphibians have large genomes, and some are polyploid. Chen et al. (2025) ask how polyploidy affects organismal physiology in a unique population of Microhyla fissipes, which has individuals with diploid and tetraploid genomes. Read more of this #AWNews at AmphibiaWeb.org.

I’m currently visiting the incredible Yuan Lab at Southwest University in China, where I’ve had the chance to explore the stunning herpetofauna. Here's a short photo thread of some fascinating species 🐍🦎🐸

Excited to share our new paper in #MolEcol on sex chromosome evolution in African killifish! 🐟 A great collaboration with @alexandrsember.bsky.social . We uncovered ≥4 sex chromosome turnovers across Nothobranchius spp. using cytogenetics & genomics.

I’m currently presenting my poster at #SMBE2025
Poster ID: S2-P05
Topic: Sex chromosome evolution in Australian burrowing frogs Neobatrachus 🐸
Would love to discuss with anyone interested, come by if you’re around! @stevedonnellan.bsky.social , Scott Edwards suggested I send you our photo together 😊

Recombination-aware phylogenomics Phylogenetic variation, recombination rate evolution, and comparative genome structure and organization have typically been explored in isolation. The chromosomal and genomic context of selected genetic markers in phylogenetic studies is usually unknown, given the fragmented nature of most genome assemblies. It is now established that the position of markers in the genome can strongly influence the inferred phylogeny, often not reflecting speciation patterns and subsequent bifurcating tree structure but rather post-speciation introgression. The recent availability of chromosome-level genome assemblies and advances in estimating genome-wide recombination rates have created opportunities to jointly understand the interplay of chromosome evolution, the landscape of recombination, and phylogenetic signal.

Off to the #ICAR2025 Concurrent Sessions! Concurrent 3 in the former Bijloke Abbey refectory on Arabidopsis relatives, started by Polina Novikova from @raphmercier.bsky.social department @mpipz.bsky.social who’s reporting on her research on natural variations of polyploidy in Arabidopsis species.

We show how tiny mutations—point mutations and kb-level indels—can shape the massive structure of Arabidopsis centromeres.

Super cool pattern! Just curious that is one of these chromosomes a sex chromosome

That’s a wrap on the Cologne Spring Meeting 2025! A huge thanks to all participants, speakers, and organizers for making this event a wonderful success. Stay tuned for more news and discoveries from TRR341 and the world of plant science. #CologneSpringMeeting2025 #PlantScience #TRR341 #DFG

Excited to be part of this project! Follow the starter pack for more great repro evo researchers!

Cologne Spring Meeting was so much fun. I was happy to see everyone and finally present some progress on North American Arabidopsis lyrata selfers.
