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

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

Plots showing: A,B) fly attack rate varies across cricket populations; C,D) genomic regions underlying common male-silencing phenotypes, flatwing and curly-wing; E) evidence of fly attack rate influencing allelic variation at multiple sites in the genome, most notably in the genomic regions underlying the curly-wing phenotype.

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

Plots showing discrete genetic linkage and clustering of samples in PCA across several chromosomes of the cricket's genome, supporting the presence of several very large structural variants

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

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...

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