We evaluated the linkage between genetic diversity and habitat suitability index (HSI) of aquatic animals including freshwater fishes, amphibians and macroinvertebrates in the Natori River basin located at the middle of Miyagi prefecture. The HSI has been structured by variables calculated from a distributed hydro-thermal model and GIS based geographical variables. We found a strong positive correlation between genetic diversity and HSI in one caddisfly (Hydropsychidae), indicating that a prospective habitat (i.e., locality which has high HSI) might contribute to increase in genetic diversity. The genetic diversity of one caddisfly (Hydropsychidae) had significant positive correlations with the HSIs of predatory fishes and aquatic insects. This result suggests that exposures to predation pressure can enhance genetic diversity. We derived negative correlations between genetic diversity and the HSIs within niche competitors, suggesting inter-species selective pressure constrains intra-species genetic diversity.
