Azolla-Anabaena azollae Relationship: V. N(2) Fixation, Acetylene Reduction, and H(2) Production

In order to characterize the reactions catalyzed by nitrogenase in the Azolla-Anabaena association, ¹⁵N₂ fixation, C₂H₂ reduction, and ATP-dependent H₂ production were measured in both the Azolla-Anabaena complex and in the alga isolated from the complex.

Methodology of biological thought in works of V. N. Beklemisheva (1890-1862)

During his work in Perm University (1918-1932) Vladimir Nikolaevich Beklemishev created theoretical and methodological foundations for the concepts of constructive morphology and structure of the living cover of the Earth. His conclusions about topical problems of general biology are still valuable for biological thinking.
