Is there a common response to ultraviolet-B radiation by marine phytoplankton?

Creator:

Behrenfeld, Michael J., Chapman, John W., Hardy, John T., and Lee II, Henry

Abstract:

Global increases in ultraviolet-B radiation (UVBR) have the potential to alter marine primary production and to affect carbon cycles and marine trophic dynamics. Estimates of UVBR induced photoinhibition have varied greatly, indicating that a common dose-response by marine phytoplankton may not occur from place to place. An action spectrum describing...

Recolonization of sediment-associated microalgae and effects of estuarine infauna on microalgal production

Creator:

Davis, Michael W. and Lee II, Henry

Abstract:

Experiments were performed to determine the rate of recolonization of sediment-associated microalga and effects of infauna on microalgal biomass and production. Estuarine sediment was defaunated and transplanted to the field and the laboratory. Recolonization of sediment by flora and fauna, relative to control sediment, was measured by chlorophyll a, gross...
