| barriers to cross-fertilization between populations of a widely dispersed polychaete species are unlikely to have arisen through gametic compatibility arms-races. | although there are theoretical reasons to suspect that gametic incompatibility may develop readily among populations of broadcast spawning marine invertebrates, there have been very few studies documenting geographic patterns of interpopulation incompatibility for any species. to address this we determined how successfully individuals of the intertidal serpulid polychaete, galeolaria caespitosa, can cross-fertilize within and among populations from across temperate australia. fertilization assay ... | 2008 | 18803690 |
