Top-down control of phytoplankton by oysters in Chesapeake Bay, USA: Reply to Newell et al. (2007)
Lawrence R. Pomeroy1,*, Christopher F. DElia2, Linda C. Schaffner3
ABSTRACT: Recently published models, which allow for spatial and temporal matching of oyster and phytoplankton populations in mainstream Chesapeake Bay, support the conclusion of Pomeroy et al. (2006; Mar Ecol Prog Ser 325:301309) that oysters cannot, and could not, control the spring blooms that are the ultimate cause of summer hypoxia. We enlarge upon our earlier exposition of how top-down and bottom-up processes interact in Chesapeake Bay to permit the occurrence of phytoplankton blooms in spring, but not in summer.
KEY WORDS: Oyster · Hypoxia · Filter-feeders · Phytoplankton blooms
