Long-term dynamics of phytoplankton from a small shallow lake in central Japan

Lake Shibire is a small shallow lake located on the top of a mountain. Although only two camping lodges stand around this lake, several tens of thousands of people visit there every year for fishing, camping and trekking. There are few limnological studies about this lake except for a series of surveys carried out by KURIYAGAWA (1981). In this paper, long-term dynamics of phytoplankton was studied in relation to the lake's environment.
