Team fish - we need your help! We are trying to build a database of all the fish chromosome-scale genomes where sex chromosomes have been identified. Have you build one or some? Do you know someone who has? Can you post the link in the comments? Please spread the word and repost! Thank you!

Pre-print and weird repro thread time! I've posted here about scale insects a lot, but ~half of my research is on Lepidoptera. My lab is developing bagworm moths (Psychidae) as models for comparative genomics. You probably know them like you see in the pics below: caterpillars that make cases.

Our whitepaper on #ProjectPsyche is online now in @cp-trendsecolevo.bsky.social! Psyche will generate reference genomes for all European butterflies. Just imagine what we’ll be able to learn from them. And if you can’t quite imagine it, have a look at the piece. :)

Hospodářská, @petrnguyen.bsky.social et al. investigated genome size and karyotype in Polyommatus and Lysandra butterflies, rejecting polyploidy to confirm karyotypic diversification via chromosome fragmentation in Polyommatinae butterflies. 🔗 doi.org/10.1093/gbe/evaf157 #genome #evolution

(1/6) 🦋 We are thrilled to announce the release of the 1,000th reference genome of Lepidoptera species found in Europe! This goal was reached with the release of Stenoptilia islandicus, also known as the mountain plume moth. Read the story below!👇🏽

PhD position in Butterfly Conservation Genomics at the Czech Academy of Sciences. Applications due by Sept 12, 2025. Requires a Master's degree. Details: https://www.prf.jcu.cz/en. Apply: [email protected]. #phd

With #eseb2025 coming to a close, it is time to start making plans for 2026. Interested in the interface of evolution 🧬 and ecology 🌳? Come to our #ExE conference hosted by @uniexecec.bsky.social in beautiful #Cornwall. Leave your email address at tinyurl.com/EvolxEcol to join our mailing list!

As expected, the scientific content of the meeting is being truly outstanding, we will have over 600 talks and over 1000 posters on display. Plenty to choose from and many opportunities for unexpected eye-opening discoveries for anyone. #eseb2025

#eseb2025 has started. So many friends and colleagues around. This is amazing. Welcome everyone to Barcelona!

Another paper on polyommatine blue butterflies just published in @genomebiolevol.bsky.social. Blues have high chromosome numbers associated with increased diversification and their karyotypes reveal strategies to maintain genomic integrity amidst profound karyotypic changes doi.org/10.1093/gbe/...

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. 👉 onlinelibrary.wiley.com/doi/10.1111/...

New paper out now in #ProcB @royalsocietypublishing.org We explored how sex loss shapes gene expression patterns by comparing sexual & asexual aphid lineages 🧬🪲 🔑 #SexualAntagonism #Parthenogenesis #Asexuality #Transcriptomics #SexBiasedExpression #SexualDimorphism 🔗 doi.org/10.1098/rspb...

Another grant application submitted. The toll of sleep deprivation near the finish line feels heavier and heavier as I get older. 🤦🥱

Register for the International Workshop on Molecular Biology and Genetics of Lepidoptera! Let us meet on Crete! 😁

Our miRNA story is now in @science.org ! We found a microRNA, not a protein, that finally solved a long-standing evolutionary mystery of wing coloration in butterflies and moths. (1/n) www.science.org/doi/10.1126/...

2 New #PhD positions in my institution to study #biodiversity and interactions #ants and #beetles in the tropics!

@odedrechavi.bsky.social is here! I am so relieved. 😆So hello new place in the sky!
