Abstract: The explosive adaptive radiation of Haplochromine cichlids in Lake Victoria, East Africa, produced 500 endemic species within only 15,000 years. A paedophage or an egg-eater is considered a unique example of trophic adaptation. Many field studies reported that more than 200 cichlids have extinct due to the upsurge of Nile perch, a carnivorous species introduced to the lake in the 1950s. Especially, piscivorous cichlids like paedophages were critically damaged by Nile perch predation. Here, we performed a genom… Show more
