COVER Microscopic marine plants (Chaetoceros, a chain-forming diatom) are consumed by zooplankton animals (Neogloboquadrina, a foraminifera, lower inset; tail of Neocalanus copepod, upper inset). Marine plankton food webs can affect climate by regulating the removal of carbon dioxide in surface waters and transporting this carbon to the deep sea via sinking particles. See page 567.
