| Research Abstract |
We investigated how ecosystem has responded to human activity on the basis of analyses of carbon stable isotope ratio of the fossil land snails. In addition, evolutionary changes caused by anthropogenic impacts was estimated by historical records. The results of these surveys showed that evolutionary changes in shell color and shape and habitat preference have occurred since human colonization. Some of these changes were caused by impacts of nonnative species. Evolutionary changes by human activity cannot be ignored in planning conservation programs for endangered species.
