Abstract
This study describes the metabolism and structure of phytoplankton communities during seasonal periodicity and discusses strategies of development adopted by species during succession. The study was conducted in two trophically different lakes. Each lake demonstrates a different degree of the ecological succession, which prescribes an increasingly complex taxocenose. In oligomesotrophic Lake Pavin the autogenic succession lasts from spring overturn until mid-summer. In eutrophic Lake Aydat the autogenic succession is strictly limited to spring. The seasonal changes of the community productivity, turnover rate (P/B) and adenylate energy charge confirm the hypothesis of a change of the ‘metabolic orientation’ of phytoplankton cells during seasonal succession. The autogenic succession represents the progression from a growth-oriented strategy to an equilibrium-oriented one.
