“…presence followed an evident periodicity within the calendar year in most of the areas studied, with maximum abundances recorded in the winter-spring months and negligible abundances in summer and autumn. Seasonal periodicity has also been reported in other studies from the Thermaikos Gulf, Greece (Koukaras & Nikolaidis 2004, Nikolaidis et al 2005, several European countries (Bernardi Aubry et al 2000, Vale & Sampayo 2003, France & Mozetič 2006, Ninčević-Gladan et al 2008, and worldwide (Koike et al 2000, Morton et al 2009, Swanson et al 2010). The only deviation between studies from different countries concerns the exact time period in which maximum abundances occur within the calendar year, which is a result of differences in the timing of seasonal climate periodicity and hydro-chemical parameters in different geographic regions.…”

“…Seasonal periodicity of Dinophysis spp. presence during the year is common in Thermaikos Gulf, Greece (Koukaras & Nikolaidis 2004, Nikolaidis et al 2005, in other European countries (Bernardi Aubry et al 2000, Vale & Sampayo 2003, France & Mozetič 2006, Ninčević-Gladan et al 2008) and worldwide (Koike et al 2000, Morton et al 2009, Swanson et al 2010. These seasonal patterns seem to be partly related to regional parameters influencing Dinophysis blooms, such as the movement of water masses due to different densities or winds (Lindahl & Andersson 1996, Moita & da Silva 2001, temperature (Reguera et al 1995, Hoshiai et al 1996, Dahl & Johannessen 2001, Godhe et al 2002 and rainfall (Vale & Sampayo 2003).…”

Presence of Dinophysis spp., the main phytoplankton genus responsible for the occurrence of lipophilic biotoxins of the okadaic acid group (Diarrhetic Shellfish Poisoning; DSP) in Greek mussels, was recorded in the period 2003-2008 in five major mussel culture areas of Greece. Dinophysis spp. abundances were simultaneously studied with climatological parameters (air temperature, rainfall, wind direction and velocity) and the occurrence of DSP toxic episodes in mussels. Dinophysis spp. blooms occurred with a seasonal periodicity. Highest cell abundances of the bloom appeared steadily between late winter and spring, whereas occurrence of DSP toxicity in mussels followed a similar time pattern, with mouse bioassay-positive samples ranging between 10.2-28.1% of the total samples analysed. Maximum mean Dinophysis spp. counts coincided with air temperatures in the range of 10-20°C; abundances higher than 1,000 cells L 1 were more frequently recorded at air temperatures in the range of 4-20°C in combination with low rainfall and low velocity winds (

“…Two studies have reported the existence of diol-esters of DTX1, both relying on MS/MS data of P. lima extracts (Morton et al, 2009;Vale and Sampayo, 2002). The presence of DTX1-D8 was proposed after the detection of a compound in the transition windows 960.7 / 237.1 and 960.7 / 765.6 in P. lima cells collected in the Black Sea (Morton et al, 2009).…”

a b s t r a c tMarine dinoflagellates of the genus Dinophysis can produce toxins of the okadaic acid (OA) and pectenotoxin (PTX) groups. These lipophilic toxins accumulate in filter-feeding shellfish and cause an illness in consumers called diarrhetic shellfish poisoning (DSP). In 2008, a bloom of Dinophysis led to the closure of shellfish harvesting areas along the Texas coast, one of the first DSP-related closures in the U.S. This event resulted in a broad study of toxin production in isolates of Dinophysis spp. from U.S. waters. In the present study, we compared toxin profiles in geographical isolates of Dinophysis collected in the U.S. (Eel Pond, Woods Hole MA; Martha's Vineyard, MA; and Port Aransas Bay, Texas), and in those from Canada (Blacks Harbour, Bay of Fundy) and Chile (Reloncavi Estuary), when cultured in the laboratory under the same conditions. For each isolate, the mitochondrial cox1 gene was sequenced to assist in species identification. Strains from the northeastern U.S. and Canada were all assigned to Dinophysis acuminata, while those from Chile and Texas were most likely within the D. acuminata complex whereas precise species designation could not be made with this marker. Toxins were detected in all Dinophysis isolates and each isolate had a different profile. Toxin profiles of isolates from Eel Pond, Martha's Vineyard, and Bay of Fundy were most similar, in that they all contained OA, DTX1, and PTX2. The Eel Pond isolate also contained OA-D8 and DTX1-D7, and low levels (unconfirmed structurally) of DTX1-D8 and DTX1-D9. D. acuminata from Martha's Vineyard produced DTX1-D7, along with OA, DTX1, and PTX2, as identified in both the cells and the culture medium. D. acuminata from the Bay of Fundy produced DTX1 and PTX2, as found in both cells and culture medium, while only trace amounts of OA were detected in the medium. The Dinophysis strain from Texas only produced OA, and the one from Chile only PTX2, as confirmed in both cells and culture medium.Published by Elsevier Ltd.

“…When it bloomed in the summer of 1986, severe oxygen depletion in the water column also occurred, and dead decapods and fish covered the whole Bulgarian coastal zone (Bodeanu, 1995). Since then, several blooms and checklists including potentially harmful dinoflagellates were reported from various countries of the eutrophicated Black Sea (Morton et al, 2009;Baytut et al, 2010). It was found (GEOHAB, 2006) that HAB events are gradually increasing in number due to the eutrophication process, and potential outcomes such as shellfish mortality and human illnesses may result if the system experiences more HABs.…”

IntroductionDinophytes are unicellular flagellates and they are commonly called dinoflagellates. This group is characterized by flagellar arrangement, cell morphology, and the presence of a dinokaryon, the uniquely modified nucleus of most dinoflagellates (Hallegraeff et al., 2004). The cell periplast (amphiesma) consisted of flat cisternae that appear empty in some species (naked or athecate dinoflagellates) and in other species include cellulosic plates (armored or thecate dinoflagellates) (Van Den Hoek et al., 1995). These alveolate protists are trophically diverse, and about half of the dinoflagellates are phototrophs; the other half are obligate heterotrophs, free-living, or parasitic (Moestrup and Daugbjerg, 2007). Organellar loss is very common in the evolutionary history of the dinoflagellates. However, loss of function may be more common. The loss of photosynthesis has certainly been more frequent than complete loss of plastids (Saldarriaga et al., 2001). Recently, harmful dinoflagellates have received more attention as they pervade in coastal marine systems that are especially influenced by anthropogenic activities. Severe eutrophication, nutrient imbalance, and transport of the toxic strains by ballast waters have degraded aquatic ecosystem health and have created negative consequences for public health and fisheries (Hallegraeff, 2004). Negative outcomes include six types of fish and shellfish poisoning [amnesic shellfish poisoning (ASP), azaspiracid shellfish poisoning (AZP), diarrhetic shellfish poisoning (DSP), neurotoxic shellfish poisoning (NSP), paralytic shellfish poisoning (PSP), ciguatera fish poisoning (CFP)], respiratory problems, and drinking water problems (Hackett et al., 2004). In 1942, for example, 114 people living around a coastal lagoon (Lake Hamana) in Japan died after consuming oysters and clams that were later determined to include the toxin venerupin (Grzebyk et al., 1997). This toxin was later attributed to Prorocentrum minimum (Pavillard) J.Schiller. Worldwide over 300 species can form dense blooms among over 5000 marine phytoplankton taxa, while 80 species can produce toxins (Hallegraeff, 2004). About 75%-80% of toxic phytoplankton taxa are dinoflagellates (Cembella, 2003), and they cause harmful algal blooms (HABs) that may kill fish and other marine fauna.The first HAB record for the Black Sea was reported in 1954, and the organism responsible was Exuviaella cordata Ostenfeld, a synonym of an athecate dinoflagellate P.
