| recent, allopatric, homoploid hybrid speciation: the origin of senecio squalidus (asteraceae) in the british isles from a hybrid zone on mount etna, sicily. | homoploid hybrid speciation occurs through stabilization of a hybrid segregate (or segregates) isolated by premating and/or postmating barriers from parent taxa. theory predicts that ecological and spatial isolation are of critical importance during homoploid hybrid speciation, and all confirmed homoploid hybrid species are ecologically isolated from their parents. until recently, such species have been identified long after they originated, and consequently it has not been possible to determine ... | 2005 | 16526502 |
