Attended #SAGE2026 about two weeks ago in Phuket. Presented my ongoing work on the evolutionary ecology and genomics of H. diekei adaptive radiation and met my friends and many other Indonesians and scientist working on evolution in Southeast Asia. Time well spent and of course very delicious food.

Very excited to share our new manuscript by Arif Maulana @arf-mln.bsky.social on 338 beetle genomes. It shows how beetle genomes have evolved and how this compares to fly and Lepidoptera genome evolution. It was a great pleasure to collaborate with @kamilsjaron.bsky.social and his team on this.

New preprint: 338 coleopteran genomes reveal exceptional rearrangement variation compared to other insect orders. Big congrats to @arf-mln.bsky.social, for getting this giant piece together. Big collaboration of @joanameier.bsky.social's and my groups. 🧵👇 doi.org/10.64898/202...

Phylogeny of 338 species with tips painted by the chromosomal ancestry of their contemporary genomes (well separated colours indicate only few changes, while blending indicates rearrangements). Colouring of the branches is by the number of rearrangements. The ring between paints and phylogeny indicates wether the chromosomal rearrangement was fusion dominated (brown) or fission dominated (teal) process.

Very excited to see the first chapter of my PhD out on bioRxiv! It began as a rotation project and became a pivotal part of my PhD on beetles, adding a complementary macroevolutionary perspective to my second chapter on early-stage speciation in Indonesian herbivorous ladybird beetles.

Out now in @ecol-evol.bsky.social . An article doi.org/10.1002/ece3... based on my undergrad thesis at Biology Dept., IPB University, Indonesia, almost six years ago. It asks how quickly additional RI barriers evolve when extremely divergent host-plant specialisation exists among 🐞 host races.

The Evolution of Reproductive Isolation Beyond a Strong First Barrier in Speciation Between Micro‐Allopatric Host Races of a Phytophagous Ladybird Beetle, <fi>Henosepilachna diekei</fi>

Reproductive isolation often accumulates unevenly during speciation, but when an early ecological barrier such as host-associated habitat isolation is already very strong, it remains unclear whether,...
