Diversity and distribution of Frankia strains symbiotic with Ceanothus in California

Creator:

Oakley, Brian, North, Malcolm, Franklin, Jerry F., Hedlund, Brian P., and Staley, James T.

Abstract:

Frankia strains symbiotic with Ceanothus present an interesting opportunity to study the patterns and causes of Frankia diversity and distribution within a particular host infectivity group. We intensively sampled Frankia from nodules on Ceanothus plants along an elevational gradient in the southern Sierra Nevada of California, and we also collected...

Creator:

Staley, James T., Taub, F. B. (Frieda B.), and U.S. International Biological Program. Coniferous Forest Biome

Abstract:

Nitrogen fixation rates were determined periodically by the acetylene reduction technique at three depths in each of the lakes. Fixation began in June in Lakes Washington and Sammamish and peaked during July and August. Chester Morse and Findley Lakes did not exhibit acetylene reduction activity until August and the rates...
