Climatic variability drives greater thermal tolerance breadth and enables larger range size in butterflies Abstract. Although climatic variability has been proposed to shape physiological tolerances, and in turn, species distributions, relatively few studies hav

Aerodynamic consequences of wing damage in dragonfly flapping flight Abstract. Flapping wings are the primary means by which dragonflies generate forces, but they are susceptible to damage due to their inherent fragility. Th

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
