This study investigates asymmetric reproductive character displacement in Ischnura damselflies, finding size and shape divergence in female morphs and male traits across hybrid zones.

The paper compares reproductive isolation and hybridization patterns in two damselfly hybrid zones, finding context-dependent differences in prezygotic barriers and genomic introgression.

This study examines asymmetric reinforcement of reproductive isolation in two damselfly species with female morphs exhibiting alternative reproductive strategies, finding stronger reinforcement in premating and postmating barriers.

This study uses geometric morphometrics to detect reproductive character displacement in damselfly hybrid zones, showing stronger signals in younger zones consistent with asymmetric reinforcement.

The paper tests reinforcement predictions in a damselfly hybrid zone, finding strengthened mechanical isolation in one cross direction but not all reinforcement predictions.
