陸水生物から見た日本列島の生物地理区分について

抄録

Zooplanktons and phytoplanktons have different habitat environment from one another depending on the species. Especially, with regard to water temperature, they can be classified into northern species who have a preference for low temperature, tropic species who have a preference for high temperature and a group of temperature independent species. Such biogeographic defferences coincide with the southern limit of dystrophic lake and northern limit of tropical lake, indicating that such a classification is useful as a limnobiogeographic indicator. The author proposes the new faunal realms (South Kurile & Eastern Hokkaido, Western Hokkaido & Simokita peninsula, Northern Nippon, Southern Nippon, and Ryukyu & Formosa) based on Rotatoria and Cladocera who show especially distinct limnobiogeographic distribution patterns.
