چکیده انگلیسی
Sympatric populations of the species exist in many locations and the inherent variability in the breeding seasons could allow spawning times to overlap. Artificially delaying A. marina individuals enabled fertilizations to be performed with A. defodiens at the natural spawning time in the laboratory. Both conspecific fertilizations produced 100% trochophore larvae after 120Â h, but A. defodiens oocytes failed to fertilize after incubation with A. marina sperm, in comparison to the A. marina oocytes incubated with A. defodiens sperm where 40% developed to the trochophore stage. This asymmetric gamete incompatibility may be one of a suite of mechanisms to minimise hybridisation.
