Alternative male reproductive tactics drive asymmetrical hybridization between sunfishes (Lepomis spp.).

Abstract excerpt

The potential role of alternative reproductive tactics in circumventing premating isolating mechanisms and driving hybridization between species has long been recognized, but to date there is little empirical support from natural systems. Hybridization occurs between bluegill (Lepomis macrochirus) and pumpkinseed sunfish (Lepomis gibbosus) and it is known to be asymmetrical (male bluegill × female pumpkinseed)....
