How do coevolutionary interactions begin in nature, and what are the first steps of reciprocal adaptation? Our preprint investigates these questions in a natural experiment: an introduced cricket (T. oceanicus) and its acoustically hunting parasitoid (O. ochracea) in Hawaii. shorturl.at/7llsA 1/n

Ecological genomics of a novel host-parasitoid arms-race in nature
Novel antagonistic interactions between species are expected to drive especially rapid coevolution. However, little is known about the genomic basis of such coevolution in nature because novel inter-s...

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]

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

We have a preprint out for our study testing conditions/signatures of repeated adaptation in multiple wild cricket populations. Feedback welcome! www.biorxiv.org/content/10.1...

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...

Competing adaptations maintain non-adaptive variation in a wild cricket population https://www.biorxiv.org/content/10.1101/2023.10.14.562337v1
How emerging adaptive variants interact is an important factor in the evolution of wild populations.
