“…In the subtropical estuaries of Florida subject to large freshwater inflows, the eurythermal and euryhaline character of A. sanguinea make it a competitive species throughout the year, yielding bloom events inside and outside the more typical warm season peak period of phytoplankton biomass in many Florida ecosystems. In Florida, this pattern is in contrast to bloom events of another major HAB species in Florida estuaries, the toxic dinoflagellate Pyrodinium bahamense, which is typically restricted to temperatures in excess of 25°C, reflecting the tropical nature of the species (Phlips et al 2006). Akashiwo sanguinea is indeed an alga for all seasons.…”

Abstract:Akashiwo sanguinea is a cosmopolitan dinoflagellate that has been observed to form major blooms in coastal ecosystems around the world. A. sanguinea plays a major role in the ecology of many marine environments, including coastal ecosystems with variable salinities, where its euryhaline character makes it competitive. The study involved monthly water sampling and measurement of physical-chemical parameters at four sites from the upper reaches of the Caloosahatchee Estuary to San Carlos Bay bordering the Gulf of Mexico. Major A. sanguinea blooms were observed in the Caloosahatchee estuary, with biovolume up to 30.5 10 6 μm 3 mL 1 , equivalent to 740 cells mL 1 , in the upper estuary. The latter regions of the estuary also had the greatest range of salinity and the highest total nitrogen and total phosphorus concentrations. The dynamics of blooms are discussed within the context of spatial and temporal patterns of salinity, temperature and nutrient concentrations, as they relate to hydrologic and climatic conditions.

“…Laboratory studies on cells were isolated from Malaysia (Usup, 1995) showed that the temperature limits for growth are 22-34°C, with optimum growth at 28°C. Phlips et al (2006) reported that cells of P. bahamense var. bahamense appeared in the column of water when the water temperature reached 20°C and blooms of this species formed only when the temperature was 25°C or higher.…”

As a part of an ongoing monitoring study of phytoplankton in Yemeni coastal waters, phytoplankton samples were collected from November 2012 to September 2013 at four sampling locations along the coast of Hodeida City, southern Red Sea. A bloom of toxic dinoflagellate Pyrodinium bahamense var. bahamense Plate was observed in August 2013. The population density of P. bahamense were ranged from 1.6 × 10 4 to 3.3 × 10 5 cell L -1 (accounting for 41.8 % of the overall phytoplankton community). This finding is the first observation of vegetative cells of this tropical species from the Red Sea. Water temperatures during the bloom was 32°C and salinity was 37 psu, indicating its tropical and subtropical nature. Among the phytoplankton species reported during this study, the red tide-forming species; Trichodesmium erythraeum (14.1%), Protoperidinium quinquecorne (6.3 %) and the known toxic species, Dinophysis caudata (1.4 %), and D. acuminata (1.00 %) were remarkable. It is apparent from our results that the toxic species do occur during many months of the year in the Coastal Waters of Yemen with high abundance observed in August followed by April 2013. Further studies are required to carry out the HAB monitoring for preventing the risk of HAB events that may outbreak in future at the Red Sea coast.

“…The distribution of P. bahamense var. bahamense in coastal waters of Florida suggests that the minimum temperature that limits its occurrence is 20°C (Phlips et al 2006). These temperature tolerances support po tential climate-related range expansion (Usup et al 2012).…”

The frequency and intensity of harmful algal blooms (HABs) and phytoplankton community shifts toward toxic species have increased worldwide. Although most research has focused on eutrophication as the cause of this trend, many other global-and regional-scale anthropogenic influences may also play a role. Ocean acidification (high pCO 2 /low pH), greenhouse warming, shifts in nutrient availability, ratios, and speciation, changing exposure to solar irradiance, and altered salinity all have the potential to profoundly affect the growth and toxicity of these phytoplankton. Except for ocean acidification, the effects of these individual factors on harmful algae have been studied extensively. In this review, we summarize our understanding of the influence of each of these single factors on the physiological properties of important marine HAB groups. We then examine the much more limited literature on how rising CO 2 together with these other concurrent environmental changes may affect these organisms, including what is possibly the most critical property of many species: toxin production. New work with several diatom and dinoflagellate species suggests that ocean acidification combined with nutrient limitation or temperature changes may dramatically increase the toxicity of some harmful groups. This observation underscores the need for more in-depth consideration of poorly understood interactions between multiple global change variables on HAB physiology and ecology. A key limitation of global change experiments is that they typically span only a few algal generations, making it difficult to predict whether they reflect likely future decadal-or century-scale trends. We conclude by calling for thoughtfully designed experiments and observations that include adequate consideration of complex multivariate interactive effects on the long-term responses of HABs to a rapidly changing future marine environment.
