Research Abstract |
We pursued long-term ecological surveys to understand the evolutionary history and population dynamics of dimorphism for left-right polarity in development in the tree snail genus Amphidromus. Both morphs of chirality coexist within populations, which is not possible as long as positive frequency-dependent selection occurs as known for snails that need to copulate for reproduction. We achieved behavioral analyses by recording cases ofinterchiral and intrachiral copulation, which allow them to coexist, by an infrared time-lapse video system.
