Cold tolerance and diapause within across trophic levels: endoparasitic wasps and their fly host have similar phenotypes

Simulated climate change causes asymmetric responses in insect life history timing potentially disrupting a classic ecological speciation system

This study shows that simulated climate change causes asymmetric phenological responses in two sympatric fly populations, potentially disrupting ecological speciation by reducing temporal isolation.

Rapid brain development and reduced neuromodulator titres correlate with host shifts in Rhagoletis pomonella

The paper correlates rapid brain development and reduced neuromodulator levels with host shifts in Rhagoletis pomonella, showing synchronization between life history traits and neurochemical changes.

Assessing the role of inversions in maintaining genomic differentiation after secondary contact: local adaptation, genetic incompatibilities, and drift

This study shows that chromosomal inversions can maintain genomic differentiation after secondary contact in finite populations, even with gene flux, by prolonging differentiation persistence and allowing for new incompatibilities and adaptations.

The genomics of trait combinations and their influence on adaptive divergence

The paper investigates how genetic correlations between traits influence adaptive divergence in apple maggot flies, showing that antagonistic pleiotropy shapes genomic footprints of rapid adaptation.

A rapidly evolved shift in life history timing during ecological speciation is driven by the transition between developmental phases

The study identifies the end of the pupal diapause maintenance phase as the main driver of a recently evolved phenological shift in Rhagoletis pomonella.
