Abstract

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.
