THE CONCHOCELIS PHASE OF THREE SPECIES OF PORPHYRA IN CULTURE.

abstract：:High-biomass blooms of the toxic dinoflagellate Pyrodinium bahamense occur most summers in Tampa Bay, Florida, USA, posing a recurring threat to ecosystem health. Like many dinoflagellates, P. bahamense forms immobile resting cysts that can be deposited on the seafloor-creating a seed bank that can retain the organism...
