Outline of Final Research Achievements |
The present study aimed to reveal natural selection operating upon phenotipic traits and their genomic regions concerning speciation. Our special target was divergent genital morphologies in Ohomopterus ground beetles. We sampled adult individuals from populations located in interspecific contact areas, and proceeded the construction of phenotypic and genotypic dataset for the above-mentioned aim of the study. In addition, we conducted experimental evaluation of sexual selection operating upon genital morphologies. As a result, we detected divergent sexual selection in closely related species with divergent genital morphologies, Carabus maiyasanus and C. iwawakianus. Furthermore, we analyzed distributional data of these two species using GIS and ecological niche modeling. As a result, we detected evidences for that natural selection concerning environmental adaptation is also operate in the contact area of these species.
