| Outline of Final Research Achievements |
In this study, the evolution of alternative reproductive tactics (ARTs) was examined in Lake Tanganyika cichlids where ARTs are considerably developed and diversified. Among 35 species from 7 genera of tribe Lamprologini, ARTs were found in 25 species from 6 genera. Some of species in these genera did not exhibit ARTs. These show that ARTs evolved independently of each other within this tribe. This study also showed that the evolution of sneaking tactics is related to mating system and spawning substrates.
