“…In the Mediterranean Sea among these red tide forming species, another species of Spatulodinium has been found based on DNA analysis [73]. In the Mediterranean Sea, Spatulodinium showes a wide range of temperature preference, similar to the temperature range (19-30 • C) reported in the Mexican Pacific [74]. Both N. scintillans and S. pseudonoctiluca have been considered exclusively heterotrophic and inclusion of diatoms, dinoflagellates, and dictyochophytes have been observed in their cells [74].…”

We investigated the plankton community composition and abundance in the urban marine environment of Thessaloniki Bay. We collected water samples weekly from March 2017 to February 2018 at the coastal front of Thessaloniki city center and monthly samples from three other inshore sites along the urban front of the bay. During the study period, conspicuous and successive phytoplankton blooms, dominated by known mucilage-producing diatoms alternated with red tide events formed by the dinoflagellates Noctiluca scintillans and Spatulodinium pseudonoctiluca, and an extensive mucilage aggregate phenomenon, which appeared in late June 2017. At least 11 known harmful algae were identified throughout the study, with the increase in the abundance of the known harmful dinoflagellate Dinophysis cf. acuminata occurring in October and November 2017. Finally, a red tide caused by the photosynthetic ciliate Mesodinium rubrum on December 2017 was conspicuous throughout the sampling sites. The above-mentioned harmful blooms and red tides were linked to high nutrient concentrations and eutrophication. This paper provides an overview of eutrophication impacts on the response of the unicellular eukaryotic plankton organisms and their impact on water quality and ecosystem services.A large volume of domestic and industrial wastes from the city of Thessaloniki has been directed for decades to the Thermaikos Gulf and especially its inner part, Thessaloniki Bay. In the 20 th century, these wastes were discharged in the Bay without treatment, causing the eutrophication of the system. Since 2001, wastewater treatment has been implemented, decreasing the effects of anthropogenic eutrophication [17]. Although it is generally accepted in the public that the water quality in the Thermaikos Gulf has been improved compared to 20-30 years ago [18,19], the urban front of the Thessaloniki Bay, with restricted water circulation and shallowness, still exhibits apparent red tides and algal blooms. These events are usually the cause of irritation to the public, often mentioned in the Greek media, with subsequent socio-economic consequences to the city of Thessaloniki, especially the touristic center. Despite the growing concerns of the citizens and authorities on the water quality of the Bay and particularly of the urban front, only scarce and isolated studies have been published on the abundance and dynamics of plankton community (both phyto-and protozooplankton) in the urban part of the Gulf [20,21]. On the other hand, several studies in the broader Thermaikos Gulf have focused on phytoplankton [18,22,23] and the occurrence of HABs [24,25]. However, comprehensive studies on red tides and mucilage aggregate phenomena are lacking for the Thermaikos Gulf.According to the related legislation for the ecological water quality based on nutrient pressures and the phytoplankton quality element (Water Framework Directive; WFD, 2000/60/EC) there is a need for systematic and frequent monitoring of coastal waters. Furthermore, similar to the WFD objectives are those...

“…Naked dinoflagellates that form red tides have only recently received attention (Gárate-Lizárraga et al, 2004;, 2009a. Many of these have been underestimated because they are normally deformed or destroyed by sampling nets, storage, and by traditional preservation solutions used in routine phytoplankton sampling (Okolodkov & Gárate-Lizárraga, 2006;Gárate-Lizárraga et al, 2011).…”

During a sampling on 15 December 2011 in Bahía de La Paz, a bloom of the benthic dinoflagellate Amphidinium carterae was detected. Its abundance ranged from 28.2 to 64.8 × 103 cells L–1. Cells of A. carterae varied in length from 18 to 28 μm and 13 to 18 μm in wide (n = 30). The presence of A. carterae and benthic species of diatoms and dinoflagellates at the surface could be an indicator of upwelling water generated by northwestern winds. Seawater temperature during the bloom was 20 °C. Also, new records of dinoflagellates for the Mexican coast of the Pacific are here reported: Amphidiniopsis hirsuta, Amphidiniopsis sp., Amylax buxus, Cochlodinium pulchellum, Cochlodinium virescens, Durinskia cf. baltica, Gyrodinium sp., Thecadinium sp., and Prorocentrum minimum var. triangulatum. Proliferación de Amphidinium carterae (Dinophyceae: Gymnodiniales) en Bahía de La Paz, Golfo de California Durante un muestreo realizado el 15 de Diciembre de 2011 en Bahía de La Paz se detectó un florecimiento del dinoflagelado bentónico Amphidinium carterae. Los valores de abundancia variaron de 28.2 a 64.8 × 103 céls L–1. Los especímenes de A. carterae presentaron un intervalo de tallas de 18 a 28 μm de longitud y de 13 a 18 μm de ancho (n = 30). La presencia de A. carterae, así como de especies bentónicas de diatomeas y dinflagelados en superficie podrían indicar aguas de surgencia debido a la influencia de los vientos del noroeste en esta temporada. La temperatura del agua durante el florecimiento fue de 20 °C. También se reportan nuevos registros de dinoflagelados para la costa pacífica de México: Amphidiniopsis hirsuta, Amphidiniopsis sp., Amylax buxus, Cochlodinium pulchellum, Cochlodinium virescens, Durinskia cf. baltica, Gyrodinium sp., Thecadinium y Prorocentrum minimum var. triangulatum.

The dinoflagellate genus Cochlodinium is polyphyletic, and several bloom-forming species in this genus, such as Cochlodinium helix and C. convolutum, are in need of reclassification. The molecular data revealed that the polymorphic species Gymnodinium fusus (=Ceratoperidinium falcatum, Gyrodinium caudatum, Gyrodinium falcatum, Gyrodinium sugashimanii, Pseliodinium vaubanii) is closely related to Cochlodinium helix/C. convolutum. There are significant morphological differences among the type species of Ceratoperidinium, C. margalefii, and the aforementioned species. The recent proposal of the genus Kirithra reinforces the need of the generic split between C. margalefii and Gymnodinium fusus/C. helix/C. convolutum, instead of placing all the species under the genus Ceratoperidinium. Pseliodinium is considered the earliest available generic name, and new combinations of Pseliodinium are proposed for Gymnodinium fusus, Cochlodinium helix and C. pirum (the latter considered co-specific with C. convolutum) Redefinición de Ceratoperidinium y Pseliodinium (Ceratoperidiniaceae, Dinophyceae), incluyendo la reasignación de Gymnodinium fusus, Cochlodinium helix y C. pirum a Pseliodinium El género de dinoflagelados Cochlodinium es polifilético, y varias especies formadoras de proliferaciones como Cochlodinium helix y C. convolutum necesitan una reclasificación. Los datos moleculares muestran que la especie polimórfica Gymnodinium fusus (=Ceratoperidinium falcatum, Gyrodinium caudatum, Gyrodinium falcatum, Gyrodinium sugashimanii, Pseliodinium vaubanii) está cercanamente emparentada con Cochlodinium helix/C. convolutum. Hay diferencias significativas en la morfología entre la especie tipo de Ceratoperidinium, C. margalefii, y las especies mencionadas anteriormente. La reciente propuesta del género Kirithra refuerza la necesidad de una separación genérica entre C. margalefii y Gymnodinium fusus/C. helix/C. convolutum, en lugar de emplazar todas las especies en el género Ceratoperidinium. Pseliodinium se considera como el primer nombre genérico disponible, y se proponen nuevas combinaciones de Pseliodinium para Gymnodinium fusus, Cochlodinium helix y C. pirum (esta última especie considerada conespecífica con C. convolutum).
