Plankton bacteria primarily subsist on phytoplankton production, and this is clearly seen in successions following phytoplankton blooms. In the ocean, phytoplankton and bacterioplankton live short lives (days) and interact over short distances (micrometers). In general, it has proved difficult to document such trophic coupling in terms of a correlation between chlorophyll contents of the water and bacterial abundance. Li et al. (p. 1157) analyzed serial observations of chlorophyll and bacterioplankton at several coastal and open ocean stations during the past decade and find that these microbial groups do change in tandem, increasing or decreasing together over many years.
