“…Although the taxonomy of the Prymnesiophyceae is still in a state of flux, using the treatment of Chretiennot-Dinet et al (1993) with the orders Prymnesiales, Pavlovales, Isochrysidales, and Coccolithophorales, the type of sterol found in these orders appears to be distinctly correlated to taxonomic placement. Pavlova lutheri and P. gyrans (Pavlovales) and several strains of Isochrysis (Isochrysidales) have been shown to promote excellent growth of juvenile oysters in the laboratory.…”

Sterols were identified in six marine prymnesiophyte isolates, some of which appear to have value as bivalve food. The principal sterol in Pleurochrysis carterae (Milford #961) and an unidentified prymnesiophyte (CCMP1215) was 24‐methylcholesta‐5,22‐dienol, a common sterol in prymnesiophytes. Isolates CCMP594, CCMP609, and CCMP459 contained either 24‐ethylcholesta‐5,22‐dienol or 24‐ethylcholest‐22‐enol as the major sterol. In addition, Pavlova pinguis (CCMP609) and Pavlova sp. (CCMP459) contained the unusual dihydroxysterols 24‐methylpavlovol and 24‐ethylpavlovol, which have been found only in members of the Pavlovales. Prymnesium parvum contained cholesterol without traces of other sterols. Compared to the other isolates, the quantity of sterols was extremely low in P. parvum.

“…Previous classifications have placed Amphidiniopsis, Pseudoadenoides, Roscoffia, Sabulodinium and Thecadinium in the Oxytoxaceae (Loeblich 1982, Dodge 1984, Sournia 1986, Taylor 1987, Chrétiennot-Dinet et al 1993, Fensome et al 1993, Steidinger and Tangen 1997. However, the sequences of these genera did not branch within the clade of Oxytoxum and Corythodinium (Fig.…”

“…These genera have been placed within the family Oxytoxaceae together with other planktonic genera such as Centrodinium and Schuettiella, and the sand-dwelling genera Amphidiniopsis, Planodinium, Pseudadenoides (formerly Adenoides), Roscoffia, Sabulodinium and Thecadinium (Loeblich 1982, Dodge 1984, Sournia 1986, Taylor 1987, Chrétiennot-Dinet et al 1993, Fensome et al 1993, Steidinger and Tangen 1997. The family Oxytoxaceae has been placed within the order Gonyaulacales (Taylor 1987, Steidinger andTangen 1997) or as an uncertain order within the subclass Peridiniphycidae (Fensome et al 1993).…”

Abstract. The dinoflagellate genera Oxytoxum and Corythodinium that account for more than fifty species are widespread in warm oceans. These genera have been considered synonyms and thecal plate designations varied among authors. Several planktonic and sand-dwelling genera have been placed within the Oxytoxaceae. We obtained the first molecular data based on small subunit (SSU) rRNA gene sequences of Oxytoxum and Corythodinium, including the type species (O. scolopax and C. tessellatum) and C. frenguellii and C. cristatum. The three species of Corythodinium branched together a strong support [bootstrap (BP) of 98%]. This formed a sister clade with moderate support (BP 75%) with O. scolopax that supported the generic split. Oxytoxaceae should exclusively remain for Oxytoxum and Corythodinium, as an independent group, unrelated to any other known dinoflagellate. Oxytoxum was characterized by spindle-shaped cells with an anterior narrow epitheca, an apical spine and little cingular displacement. Corythodinium exhibits relatively broad cell shapes, with wider epitheca and greater cingular displacement, and an obovate or pentangular anterior sulcal plate that noticeably indented the epitheca. This suggested the need of new combinations for species that were described as Oxytoxum and possessed the characteristics of Corythodinium.

La ubicación taxonómica por género y especie de los grupos de fitoplancton se realizó utilizando los criterios de clasificación de Sournia (1986), Round et al (1990), Chrétiennot-Dinet et al (1993) y Tomas (1994. También se obtuvieron datos de abundancia, biomasa y frecuencia de especies.…”

Seasonal variations of community structures phytoplankton in groundwater discharge areas along the Northern Yucatán Peninsula coast. The highly touristic Yucatán Peninsula is principally constituted with coastal marine environments. Like other coastal areas, this has been affected by the increase of waste water discharge, hydrological modifications and land use changes in the area. The phytoplankton community structure is one of the main components of coastal ecosystems and the most affected in hydrological processes. In order to follow the seasonal variations, the phytoplankton was characterized to follow the hydrological variability in two sites (Dzilam and Progreso) of the Northern Yucatán Peninsula. For this, cruises were carried out monthly during one year, from April 2004 to March 2005, with two samplings per season (dry, rainy and "nortes"). Hydrological variability was associated with seasonality and directly linked to groundwater discharges in the Dzilam area, and waste water discharges in the Progreso area. The highest nutrient concentrations occurred mainly during the rainy season. The phytoplankton community changes observed throughout the year suggested that the hydrological and chemical variability associated with seasonality and anthropogenic impacts have a strong influence. The substitution of diatoms by dinoflagellates as the dominant group in Progreso was the result of seasonal variability itself, but also could have been caused by eutrophic processes; while in Dzilam, the major presence of diatoms could have been favored by groundwater discharges. The results of this study can be used to understand the linkages between stressors from the anthropogenic activities and coastal water quality and changes. Rev. Biol. Trop. 60 (1): 157-172.
