| Research Abstract |
We generated ecological niche models (ENM) for several species of coldwater-adapted fishes in Japan. In the stone loach, habitat connectivity estimated from ENM was correlated with gene flow, suggesting that the ENM would have potential for representing gene flow regime (genetic population structure). Effects of climate change on population structure and genetic diversity of coldwater-adapted fishes were evaluated by using molecular genetic, phylogeographic and ENM approaches.
