摘要: Observations on thermophilic algal communities during a three-year period at Mount Rainier National Park and January 1965 1966 in Yellowstone have been analyzed to evaluate the distribution of species thermal streams relative temperature competitive interaction. Although appears be most important physical factor affecting alkaline springs, interspecific competition for space also influences distribution. Diatom commonly occurring above 35C are noted, along with apparent tolerance by certain temperatures excess 45C. The diversity diatom flora increases as water cools. Despite chemical constancy, growth rate algae is negligible winter months when light minimal.
