VARIABILITY IN THERMAL SENSITIVITY OF ADULT REPRODUCTIVE DIAPAUSE IN THE SPRUCE BEETLE, DENDROCTONUS RUFIPENNIS

This study examines variability in adult reproductive diapause termination in spruce beetles under lab and field conditions, finding that some individuals can reproduce under warm conditions and that field temperature fluctuations may rapidly terminate diapause.

Variation in thermal sensitivity of diapause development among individuals and over time drives life history timing patterns in a univoltine insect

The paper models thermal sensitivity of diapause development in apple maggot flies, showing that incorporating individual and ontogenetic variation improves predictions of emergence timing.

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.

Transcriptomic and functional genetic evidence for distinct ecophysiological responses across complex life cycle stages

The paper uses RNAseq and RNAi to show that thermal physiological responses in Drosophila larvae and adults are largely distinct at the gene expression level.

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.
