I am so excited to see this preprint out. I started working on springtails with @laurarossevo.bsky.social in 2019, but this pinnacle of our efforts manifested only with heroric leadership of Sam Ebdon! So, what's the deal? 👇

Congrats Jack!! 🦗🧬 So excited to see this one out—fantastic work! This work investigates how cricket populations have adapted at the genomic level following the introduction of the parasitoid fly and show how this novel selective pressure has shaped both population structure and genetic variation.

Thanks! Yes sorry, I should be more specific. This pipeline is designed for a single whole-genome sequence, so target capture with multiple individs would not ve suitable. A outgroup ref would work but depends on genetic divergence from focal spp. hope that helps.

Genes under selection in Hawaiian O. ochracea also show episodic positive selection across other parasitoid flies, suggesting that long-term host–parasitoid arms races have repeatedly shaped parasitoid genomes over evolutionary time. 6/n

Leeban Yusuf @leebanhy.bsky.social · 06/07/2026
Despite clear signatures of founder effects and population bottlenecks in Hawaiian O. ochracea, we detect robust recent selective sweeps likely driven by host adaptations. The genomic evidence suggests rapid counter-adaptation within only ~300 generations. 5/n

Leeban Yusuf @leebanhy.bsky.social · 06/07/2026
These mutations are heritable, vary in how they disrupt wing development, and are under strong selection driven by reduced detectability. Here, we asked whether the flies have begun to counter-adapt. We resequenced 358 O. ochracea across 27 Hawaiian sites, spanning four islands, plus outgroups. 4/n

Leeban Yusuf @leebanhy.bsky.social · 06/07/2026
Over the last ~20 years, adaptive mutations disrupting male sound production have risen to appreciable frequencies across Hawaiian T. oceanicus populations, making male crickets increasingly difficult for flies to detect. 3/n

We also found little difference in rates of long-term gene flow, divergence times or ancestral population sizes between allopatric and sympatric pairs. In short: present-day geographic ranges tell us surprisingly little about Drosophila speciation histories. [5/6]
131
Leeban Yusuf @leebanhy.bsky.social · 15/01/2026
Coyne & Orr’s work also supported reinforcement: strengthening of reproductive barriers following secondary contact. When we fit a secondary-contact model, only 8 (all sympatric) pairs were best explained by this model, suggesting reinforcement may be less important than assumed. [4/6]

Leeban Yusuf @leebanhy.bsky.social · 15/01/2026
We analysed whole-genome data from 93 Drosophila species pairs, a subset of those studied in Coyne & Orr (1989, 1997), using a range of demographic models. Only 12 fit strict allopatry. The remaining 81, including many currently allopatric pairs, showed considerable support for gene flow. [3/6]
120
Leeban Yusuf @leebanhy.bsky.social · 15/01/2026
Allopatric speciation has long been thought to be common, because reproductive isolation can evolve unimpeded by gene flow. But genomic studies increasingly show that gene flow is widespread. So, which is actually more common: strict allopatry, or speciation with gene flow? [2/6]

Leeban Yusuf @leebanhy.bsky.social · 15/01/2026
New paper out: “allopatric” Drosophila species aren’t so allopatric after all. We show that most currently allopatric species pairs probably overlapped in the past and exchanged genes at levels similar to sympatric pairs. @evolletters.bsky.social doi.org/10.1093/evle... [1/6]
