Join us at #SMBE2026 in Copenhagen this summer! 🔵 With @ergabiodiv.bsky.social & @official-smbe.bsky.social 🟣 Symposium 21 | From genomic graphs to evolutionary insights: standardising #pangenomes for population inference 🟢 smbe2026.org/programme/ #biodiversity #genomics

Genutis et al. used data from an hybrid Drosophila cell line to show that pairing among trans homologous chromosomes was affected by the presence of nearby TEs. Mouse data show a similar pattern, suggesting a highly conserved TE-pairing association. 🔗 doi.org/10.1093/gbe/evaf222 #genome #evolution

How does population size shape the dynamics of structural variants across the genome? Check out our new paper in @science.org www.science.org/doi/10.1126/...

Are you excited about pangenomics? If so, join us in Edinburgh on 8-9th June to discuss the latest methods & insights from using these approaches across biodiversity! More details here: royalsociety.org/science-even... Organised together with @henrylnorth.bsky.social & @joanameier.bsky.social!

Our paper on ancestral conditions of caddisflies (described in the quoted post) is now out! doi.org/10.3897/zook...

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.

How many types of butterfly can you recognise? 1000 species of butterfly and moth have been genetically sequenced, as part of a project to map the genome of all 11,665 species in Europe, co-led by Darwin Research Fellow Dr Charlotte Wright. www.darwin.cam.ac.uk/news/sequenc...

We all wish peer review to be rapid and professional: doesn’t always go like that. But I am relieved to finally see Helixer by @alisandra-denton.bsky.social and team published in Nature Method. Congratulations! www.nature.com/articles/s41...

I'm very excited that our paper on Project Psyche is now published! 🦋🧬 Over the last two years we've built an incredible community & already made huge progress. Read about this & how @projectpsyche.bsky.social will drive exciting and collaborative science here: www.cell.com/trends/ecolo...

We need your help! If you have a few minutes, please fill out a very short survey about your preferences on butterflies and art - all responses are welcome! www.unveiling.eu This is part of a project that aims to understand how the beauty of butterflies influences conservation: Unveiling (1/2)

How do new centromeres evolve while staying compatible with the division machinery? Discover it in our new Nature paper! We show centromeres transition gradually via a mix of drift, selection, and sex, reaching new states that still work with the kinetochore. 👉 doi.org/10.1038/s41586-025-09779-1

Happy to present TOGA2, developed by Yury Malovichko @ymalovichko.bsky.social, the faster, memory-efficient & more accurate TOGA1 successor (github.com/hillerlab/TO...). And annotations, orthologs & gene loss/dup data generated with 4 references for 883 placental mammal and with 5 refs for 676 ...

Latest work out today in @currentbiology.bsky.social We find the fly development gene bicoid is much older than previously thought (~20 million yrs older!) 🪰🧬 To pinpoint its origins we tackled the Diptera phylogeny, providing some resolution (many open questions remain). 🔗 tinyurl.com/2vyuevpy

Do you use genomic data to study Lepidoptera in Europe? Do you want to visit a lab to learn a new skill or build a new collaboration? If so, you should apply for a short term scientific mission! These are small grants to fund research exchanges as part of our Lep10K COST action. All info below!

It's out, Minos transgenesis in the pantry moth by @donyaniyaz.bsky.social @lucalivraghi.bsky.social High efficient, glowing eye and silk gland markers peerj.com/articles/202... @peerj.bsky.social

What a remarkable discovery! In SW Turkey a new species of Lycaenid was discovered, Rapala suleymani sp.n., of a genus that was only known from the eastern palearctic & indomalayan realms, it's closest relative flies 7000km away! doi.org/10.31184/M00...

A fantastic writeup by Glenn Zorpette from @spectrum.ieee.org. Glenn joined us in Italy where we collectively sampled hundreds of new species for @projectpsyche.bsky.social. Shoutout to Luigi Avantaggiato for the spectacular photos and @costprogramme.bsky.social funding for bringing groups together.

It is so nice to finally see the first paper of my PhD published! It was possible thanks to invaluable contributions of Andrea Chiocchio, @mariaheikkila.bsky.social, @jadrankarota.bsky.social, Lauri Kaila, and @lepphylo.bsky.social.

Claire Merot opens the afternoon session at the #biodiversity25 with a presentation about the structural genetic diversity across the tree of life. Structural variants (SVs) are in order de magnitude higher than SNPs. TEs accounts for many SVs. SVs are different across different lineages.

New preprint! We unexpectedly discovered that some Caenorhabditis species delete parts of their somatic genome early in development, which fragments their chromosomes and eliminates key germline genes. Multiple lines of evidence suggest this bizarre process was present in the ancestors of C. elegans

Programmed DNA elimination was present in the last common ancestor of Caenorhabditis nematodes https://www.biorxiv.org/content/10.1101/2025.10.23.681605v1

Really nice paper from @tiff-ki.bsky.social & co. shows no overall decline in butterfly species richness in Sulawesi over 166 yrs, but changing communities with endemics & forest specialists declining. Short-term trends unreliable measures of long term. royalsocietypublishing.org/doi/10.1098/... 🌏

The new European Butterfly Red List is published today, with worrying findings. Over 1/4 (28%) of Europe’s 442 species are threatened with extinction or are close to being so. The situation is far worse for our 148 endemic species, 40% are now threatened or nearly so www.bc-europe.eu/webpage.php?...

🚀 Second STSM of 10kLepGenomes! Jakub Tetla (Jagiellonian Univ., Poland) visited @jadrankarota.bsky.social (Lund, Sweden) from 24–26 Sept 2025. The goal was to integrate museum collections with phylogenomics to study West Palearctic tiger moths. #10kLepGenomes #Lepidoptera #Museomics

This week we celebrated reaching 1000 lepidopteran genomes in the Tree of Life (ToL) programme @ the @sangerinstitute.bsky.social with butterfly crafts and cake! Many of these genomes were sequenced by the wonderful ToL teams as part of @projectpsyche.bsky.social & the Darwin Tree of Life project 🦋🧬

Now published! Our paper on: (1) Accurate sequencing of sperm at scale (2) Positive selection of spermatogenesis driver mutations across the exome (3) Offspring disease risks from male reproductive aging [1/n] www.nature.com/articles/s41...
