Exciting news!
The next #PopGroup meeting will take place in Lille 🍟, France, 7–9 January 2026 – just 1 hour by train from London, Brussels, and Paris.

This year, PopGroup will also host ALPHY, the annual meeting of Evolutionary Genomics.

Good memories of fieldwork collecting butterflies and moths for @projectpsyche.bsky.social in Italy with lepidopterists from across Europe. We identified, dissected and preserved them onsite for optimal conditions to sequence reference genomes. In a few weeks we will reach 1000 genomes!

(1/7)🦋 A brief recap from Mals (Malles Venosta, Italy): In mid-July, over 50 experts from 19 European countries gathered for the first field workshop funded by the CA10KLepGenomes, aiming to sequence the genomes of all European Lepidoptera within @projectpsyche.bsky.social.

Thanks for the amazing science from your group, Joana! 👍 The butterflies took us on a fascinating flight into the tangled chromatin genealogies in the fragrant rainforest community evolving through Pleistocene glacial cycles. 🏔️Such a rich piece!! #biogeography #genomic #speciation

Genomics of Neotropical biodiversity indicators: Two butterfly radiations with rampant chromosomal rearrangements and hybridization | PNAS
A central question in evolutionary biology is what drives the diversification of lineages. Rapid, recent radiations are ideal systems for this ques...
www.pnas.org
joanameier.bsky.social
Despite the rearrangements, we find evidence of past hybridisation throughout the evolutionary history of these radiations. Multiple species show strongly admixed ancestries, indicating that hybridisation may have facilitated their evolution. This is something we are currently investigating more.
joanameier.bsky.social
We find that dozens of new species evolved within just 1-2 million years, coinciding with drastic changes in climate during the Pleistocene ice ages. The species show vastly rearranged genomes with many chromosomal fusions and fissions, likely contributing to their rapid diversification.

Our paper, led by Eva van der Heijden, shows the work of an international team combining phylogenomics, hybridisation tests, population and comparative genomics and pheromone analyses to resolve the taxonomy and evolution of two rapid radiations of glasswing butterflies. www.pnas.org/doi/10.1073/...

Huge thanks and congrats to @siluwang.bsky.social and Anne Yoder for organising this amazing special issue. It has been fun contributing and interacting with Silu, Anne and the authors of the other manuscripts, including in a Zoom "tea break" where we presented our projects to each other.

Why do treehoppers look so weird?! Our latest paper, out this week in @pnas.org, suggests a perhaps unexpected reason - static electricity ⚡ We show that treehoppers can detect the electrostatic cues of predators and that their crazy shapes may boost their electrosensitivity! doi.org/10.1073/pnas...

Experts have remapped the evolutionary tree of glasswing butterflies found across Central and South America, highlighting six new species.

This research helps track biodiversity and reveals genetic insights into how these insects evolve into new species.

Wanna see what it was REALLY like collecting data in the rainforest for our recent @pnas.org paper? I made a wee video about it, on YouTube now. As usual, thanks to my amazing field-assistant-turned-camera-operator Theodora for most of the sweaty Ecuadorean mug shots… 😇

thanks everyone for respecting the fact that i'm going to have to promote my book all the time now and while i'm excited about it i also know that promotion is awkward and weird and i'm just gonna push through and try to stay excited

if you get annoyed, please just keep scrolling, you'll be ok

Ultimately, this means that I can use my birds to both produce data, and back it up.
