Data for: Relationships between reproductive character displacement in genital morphology and the population-level cost of interspecific mating: Implications for the Templeton effect

Taira Nishimura, Karen Terada, Tian Xia & Yasuoki Takami
Natural selection against maladaptive interspecific reproductive interactions may cause greater divergence in mating traits between sympatric populations than between allopatric populations in a pair of species, known as reproductive character displacement (RCD), evidence for the lock-and-key hypothesis of genital evolution. However, the relative importance of various processes contributing to RCD in genital morphology (e.g., reinforcement, reproductive interference, and population filtering or the Templeton effect) is not clear. Here, we examined hypotheses for RCD in genital...
