;
Carbon-14 grain density autoradiography was used to qualitatively assess the changes in photosynthetic activity occurring throughout the course of a year within the three dominant phytoplankton populations in Lake Tahoe. Lake Tahoe is an ultraoligotrophic subalpine monomictic lake situated at 1898 m in the Sierra-Nevada-mountains of California and Nevada. Diatoms dominate the lake phytoplankton.
