To celebrate the genomes for 1,000 (!) species of Lepidoptera in Europe, Project Psyche has released a preprint outlining our ambitions to jointly sequence & leverage genomes of all 11,000 species in Europe to propel science, conservation & society.

This was a joy to write together as a community!

Nature research paper: Global phenology maps reveal the drivers and effects of seasonal asynchrony

Ripple bugs use a special fan-like structure on their middle legs to speed and steer through turbulent waters. In a new Science study, researchers report a water-walking robot inspired by this feature.

Two last two things:
This paper comes from the thesis project of a super star MSc student @uu.se, Cesc, who put in a tremendous amount of work. By the way, he's looking for a PhD in case anyone is interested... #ProudPI

Want to make recombination maps from sperm/pollen/gametes? There is an easy way, based on Hi-C sequencing.

Some 4.3 million observations of butterflies show that 59 of 136 species have declined in abundance over the past three decades, while no species has increased in abundance. Butterfly declines undoubtedly have large ecological consequences. In PNAS: www.pnas.org/doi/10.1073/...

6/6) Our study shows how long-distance dispersal and species interactions can shape diversification and biogeographic patterns over evolutionary time — driving disjunctions at both population and species levels.

5/6) Ecological niche modeling further supports a scenario where the establishment of V. atalanta in Europe displaced V. indica to Asia. This, in turn, caused the current disjunction between V. indica and its sister species V. vulcania, which is endemic to the Macaronesia.

4/6) Genomic analyses reveal introgression between European V. atalanta and V. indica, a species now found only in Asia. This suggests they once coexisted in Europe – a case of ancient sympatry.

3/6) We found that American and European Vanessa atalanta populations are genetically distinct. The species originated in North America and crossed the Atlantic during the Last Glacial Maximum – a rare case of natural trans-Atlantic dispersal.

2/6) Vanessa butterflies show a remarkable variation in migratory behaviour – from local endemics to obligate long-distance migrants. Some species display striking disjunct distributions across continents, either within species or between sister species.

1/6) New paper out in Molecular Ecology! We uncover the intriguing biogeographic history behind the Holarctic disjunct distributions in Vanessa butterflies. @phylomigrationlab.bsky.social
