Fantastic, they saw a Stygiomedusa on descent!! @schmidtocean.bsky.social dive 884 #argentiniandeepseeps #MarineLife #CONICET

Congratulations to team members @phil-donoghue.bsky.social, @tweethinking.bsky.social, & @ssolo.bsky.social for their newly published study on the process of eukaryogenesis.

We hope this framework will resolve historical events in individual gene families for the #WGDip project. 🧪🧬

🚨PhD position available!🚨🧪
I am seeking a talented PhD student to join my ERC StG project GEMINI, to explore the exciting world of vertebrate genomics and comparative genomics, seeking to understand the genomics of miniaturisation! 🦇🦎🦜🐸🐟🦈 🤏🧬
Deadline: 4 Jan 2026!

Congratulations!🎉

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.

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.

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.

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
