Outline of Final Research Achievements |
This study examined the effects of conspecific sperm precedence on species coexistence between closely related mating signals. I used generalist and specialist Harmon ladybirds for the mating experiments. Based on the results of the experiments, I developed the mathematical model to predict the population dynamics of the two species. I showed that the two species cannot coexist in the same niche despite the mechanism of conspecific sperm precedence. This study illustrates the underestimated significance of conspecific sperm precedence.
