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

Genomic analyses in Drosophila do not support the classic allopatric model of speciation
Abstract. The allopatric model of speciation has dominated our understanding of speciation biology and biogeography since the Modern Synthesis. It is uncon

These crickets are targeted by a parasitoid fly that is attracted to their song. We found fly attack rates vary across populations which influences allelic variation in the region underlying a protective male-silencing 'curly-wing' phenotype. Also, these crickets give birth to a new type of ant

A finding we didn't anticipate is that these small, fragmented populations share many large/very large structural variants - presumably inversions, presumably influenced by balancing selection. We don't know what their phenotypic consequences are, but they have substantial effects on gene expression

We have a preprint out for our study testing conditions/signatures of repeated adaptation in multiple wild cricket populations. Feedback welcome!

Genomic signatures of local adaptation across parasitised cricket populations
Host-parasite interactions are predicted to exhibit geographic heterogeneity, creating the opportunity for local adaptation. This is difficult to detect because it requires knowledge of selection pres...

How emerging adaptive variants interact is an important factor in the evolution of wild populations.
