Contrasting the form and strength of pre- and postcopulatory sexual selection in a transparent worm with fluorescent sperm

The paper measures pre- and postcopulatory sexual selection in a transparent worm by tracking fluorescent sperm and analyzing morphological traits to identify selection patterns on sperm production and copulatory organ shape.

Evolution and co-evolution of the suck behaviour, a postcopulatory female resistance trait that manipulates received ejaculate

This study examines the evolution of the suck behaviour in Macrostomum flatworms, showing it co-evolves with reciprocal mating and functions as a female counter-adaptation to control received ejaculate.

Self-fertilization, but not mating strategy, predicts the evolution of sex allocation plasticity in a hermaphroditic flatworm genus

The paper examines sex allocation plasticity in Macrostomum flatworms, finding self-fertilization predicts plasticity in response to mating partners, not mating strategy.

Successful mating and hybridisation in two closely related flatworm species despite significant differences in reproductive morphology and behaviour

This study examines mating behavior and hybridization between two closely related flatworm species despite differences in reproductive morphology and behavior, finding that while they can hybridize, postmating barriers and mating rate differences exist.
