Endersby 644 TECHNICAL COMMENT ABSTRACTS 644 CORRECTIONS AND CLARIFICATIONS COVER A milliliter of seawater. Motile marine bacteria can take advantage of highly heterogeneous landscapes of dissolved organic carbon, resulting from zooplankton excretions (left), leakage by phytoplankton (top) and marine snow particles (bottom), and phytoplankton lysis (right). The Gordon Research Conference on Marine Microbes will be held 4 to 9 July 2010 at Tilton School, Tilton, NH. See page 708 for a preliminary conference schedule.
