Bacterioplankton and Bacteriobenthos in Ecotone Ecosystems

ABSTRACT

Bacterioplankton of ecotone systems displayed a high living activity, as inferred from the time it takes for the numbers and biomass to increase twice and from specific respiration. Bacterial populations of water and benthic sediment included microorganisms of several trophic groups varying in nutritional requirements and growth strategy. The structural and functional features and significant short-term fluctuations in the numbers and living activity of bacterioplankton and bacteriobenthos suggested the instability of bacterial populations caused by the instability of environmental factors. These parameters are indicative of ecotone ecosystems.
