ZOOPLANKTON RESPONSE TO SMALL-SCALE TURBULENCE: COMMUNITY STRUCTURE AND RATE PROCESSES
 
We summarize here the results obtained in a series of experiments with laboratory microcosms designed to study the effects of small-scale turbulence on the development of zooplankton communities. The comparison of several descriptors of structural (i.e., taxonomic composition, biomass, size spectrum) and functional (i.e., development rate, production) properties of zooplankton under different conditions of turbulence, nutrient concentration and nutrient balance suggests that turbulence plays a significant role in the selection of the trophic characteristics of planktonic systems. The possible fate of pelagic biogenic carbon is discussed in the light of the control exerted by small-scale turbulence on zooplankton rate processes, whose cumulative effects result in structural changes in the planktonic community.
