Mechanisms for the Accumulation of High Concentrations of Dinoflagellates in a Bioluminescent Bay1

Abstract: The bioluminescent, photosynthetic, tropical marinc dinoflagellate Pyrodinium bahamense occurs in persistent high concentrations in Oyster Bay, Jamaica, W. I., although mean tidal flushing rates determined by dye-tracer techniques would predict their disappearance.As a result of a unique temporal sequence of positive phototaxis and the differential movement of diurnal wind-driven water layers of different densities, there is a daily transfer of P. bahumense into the eastern shallows of the bay where flushing r… Show more

“…As a result, interactions between swimming behavior and current shear can lead to retention of some plankton populations within relative narrow regions of estuaries and shelves, differential transport of subpopulations or life stages, or the separation of plankton populations from food sources and(or) predators (grazers). For example, these interactions have been shown to be critical for concentration of the dinoflagellate Pyrodinium bahamense in Oyster bay, Jamaica (Seliger et al 1970), for the differential transport and retention of oyster larvae in estuaries (Boicourt 1982), and for the stage separation and retention of zooplankton populations of the copepod Calanus pacificus on the Oregon shelf (Peterson et al 1979). The consequences of similar interactions is discussed below for HAB species.…”

“…It has long been recognized that such behavior can have dramatic effects on the environmental conditions experienced by the organism, its resultant physiological condition and growth rate, its ability to aggregate, and the extent of horizontal transport (Ryther 1955;Seliger et al 1970;Margalef 1978;Seliger 1993;Okubo 1994;Kamykowski 1995). In trying to quantify and predict such behavior and its impact on the individual and population, it is necessary to approach the problem from the perspective of the individual plankter.…”

“…Both phototaxis (Forward 1976) and geotaxis (Eppley et al 1968, Cullen & Horrigan 1981 have been invoked to explain the directionality of swimming behavior, with a variety of physical and chemical factors regulating the extent of vertical movement. These include nutrients (Eppley et al 1986, Cullen & Horrigan 1981, Heaney & Eppley 1981; light intensity (Harris et al 1979, Heaney & Talling 1980; temperature or salinity gradients (Seliger et al 1970, Kamykowski & Zentara 1977, Tyler & Seliger 1978; and oxygen availability (Heaney 1976, George & Heaney 1978. It is now clear that individual species can respond differently to these parameters (Eppley et al 1968, Heaney & Eppley 1981 Contribution No.…”

“…Moreover, it has been focussed primarily on their role as primary producers. It is assumed that all resting cysts form within these upper layers and, soon thereafter, sink to the bottom, where the abandoned cyst walls (loisthocysts) certainly accumulate (Seliger et al 1969, Dale 1976, Keafer et al 1992). However, upwelling or alongshore transport of living cysts or loisthocysts may complicate the eventual distribution pattern (Franks & Anderson 1992a, b, Keafer et al 1992.…”
