Abstract
It is necessary to detect accurate effects of benthic invertebrates’ communities on water temperature. Headwaters in mountains enable to detect accurate effects of benthic invertebrates on only water temperature. In order to evaluate the impacts of benthic invertebrates on water temperature, we investigated the quantitative relationship between water temperature and benthic invertebrates in the headwaters of the Natori River basin located at the middle of Miyagi prefecture. As results, the population of benthic invertebrates has a positive correlation with the number of taxa (R2=0.59, p<0.01). The Sorensen similarity index decreased significantly with the water temperature difference expanding (R2=0.15, p<0.01). The population densities of Plecoptera decreased significantly with the water temperature rising (R2=0.25, p<0.01).
