Seasonal switching between relative importance of "bottom-up" and "top-down" control of bacterial and heterotrophic nanoflagellate abundances

During summer and autumn bacterial abundance was mainly controlled by HNF grazing, whereas HNF abundance was controlled by bacterial abundance. On the other hand, during winter and spring, the coupling between bacteria and HNF was very weak, and bacterial abundance was mainly controlled by resources supply, whereas HNF abundance was controlled by microzooplankton grazing.
