“…However this area is antapical and located on the 1′′′′ plate in Cabra, Rhinodinium and Roscoffia (Hoppenrath & Elbrächter, 1998;Murray et al, 2006;Chomérat et al, 2010a), which differs from Madanidinium where it is lateral as in Prorocentrum species. In Prorocentrum panamense and P. pseudopanamense, a roundish depression with a sieve-like bottom is present on the posterior dorsal side of the right lateral plate (Hoppenrath et al, 2013) while in P. glenanicum, a group of closely arranged pores, very similar to that observed in M. loirii, is found just above the centre of the right lateral plate (Chomérat et al, 2011). To date, the role of these structures has not been ascertained, but from observations of a live culture of P. panamense, it seems that cells can extrude mucus from the pores of this area, and attach to the substratum (M. Saburova, pers.…”

“…and still needs further investigation. Indeed, most of these taxa are known only from their morphology, and it would now be of great importance to complement this knowledge with DNA sequences to better understand their phylogenetic position within dinoflagellate lineages (Hoppenrath et al, 2013).…”

Considerando lo anterior, el objetivo de este trabajo consistió en determinar la distribución y abundancia de las especies del género Prorocentrum durante un ciclo anual, en dos estaciones de muestreo ubicadas dentro del ámbito de las granjas atuneras y en una estación fuera de la influencia de las granjas en la Bahía de La Paz, Golfo de California. Las muestras de agua se recolectaron mensualmente (junio 2006-mayo 2007) con una botella van Dorn en diferentes niveles de profundidad. En San Juan de La Costa (SC) se recolectaron en superficie 25 y 50 m, en Rancheros del Mar (RM) en superficie, 15, y 30 m, y en El Mogote (M) solo en superficie. A lo largo del ciclo anual, en las granjas atuneras en la Bahía de La Paz, se registraron 12 especies: P. compressum, P. dactylus, P. emarginatum, P. gracile, P. lima, P. micans, P. minimum, P. rhathymum, P. rostratum, P. shikokuense, P. triestinum y P. vaginula, de las cuales, ocho son formadoras de florecimientos algales. El estudio de los florecimientos de Prorocentrum se ha vuelto importante ya que estos han sido relacionados por su impacto nocivo en los ecosistemas.Palabras clave: Dinoflagelados, fitoplancton, florecimientos algales, Golfo de California, granjas atuneras, Prorocentrum. ABSTRACTThe genus Prorocentrum Ehrenberg includes 81 marine species, of which 21 are considered causative agents of harmful algal blooms, and approximately 9 species produce toxins. The objectives of this study were to determine distribution and abundance of Prorocentrum species during an annual cycle at two sampling sites within tuna farms near San Juan de La Costa (SC), Rancheros del Mar (RM) and at a station without the influence of these farms located off El Mogote (M), in the Bahia de la Paz, Gulf of California. Samples were taken monthly (June 2006-May 2007 at different depths at SC (0.25 and 50 m), at the RM (0.15 and 30 m) and at El Mogote (0 m) with a van Dorn bottle. The results showed a total of twelve species in the annual cycle: P. compressum, P. dactylus, P. emarginatum, P. gracile, P. lima, P. micans, P. minimum, P. rhathymum, P. rostratum, P. shikokuense, P. triestinum and P. vaginula, of which the first eight form blooms. The study of Prorocentrum blooms became important because they have been linked to widespread harmful ecosystem impacts.

Strengths of numerical relationships between phytoplankton abundance estimates made by microscopy and CHEMTAX have often been tested using regression analysis. To specifically test agreement, where data points lie along a line of equality, the Bland and Altman technique is commonly used in the medical literature and applied here to phytoplankton analysis for the first time (simultaneously with regression). Our analyses are based on a sample set collected off Coffs Harbour ( 308S), Eastern Australia. While comparing abundance estimates of different phytoplankton pigment-types derived from microscopy and CHEMTAX we specifically aim at: (1) determining the usefulness of the Bland and Altman technique in comparing phytoplankton abundance estimates made by both quantification techniques, and (2) identifying the lowest taxonomic level (i.e., interclass or intraclass level) at which phytoplankton abundance estimates agree. Our results suggest that Bland and Altman analysis is highly suited to compare phytoplankton abundance estimates made by microscopy and CHEMTAX. It delivered a quantifiable difference of chlorophyll a concentrations between abundance estimates, which may benefit the future calibration of phytoplankton quantification techniques. Both Bland and Altman and regression analyses were suited to resolve imbalances between phytoplankton abundance estimates made by microscopy and CHEMTAX. Best agreement was found within dinoflagellates (class-level), poor agreement within three diatom pigment-types (intraclass level). We attributed the poor agreement within diatom abundance estimates to classification errors of microscopically determined taxa into pigment-types. Intraspecific pigment composition seems more variable than generally assumed, calling for studies resolving this variation to further conform abundance estimates made by microscopy and CHEMTAX.Techniques to rapidly identify and quantify phytoplankton have greatly improved over the past decades with microscopy and pigment analyses being the most commonly used methods to date. Yet, both techniques have their advantages and disadvantages and the approach of choice usually depends on the aim of the investigation, for example, to detect particular ecologically significant species or to assess phytoplankton communities over large spatial scales. Equally, minimizing costs and analysis-time, technical experience and equipment accessibility can all be additional or competing concerns in technique selection.Light microscopy has been widely applied for the identification and enumeration of phytoplankton to species level.However, due to the limited resolution of this technique, only the larger phytoplankton (>10 lm) are well distinguished. For many small-sized (<10 lm), fragile, morphologically similar or cryptic phytoplankton taxa, more elaborate approaches such as high-resolution scanning or transmission electron microscopy (Hoppenrath et al. 2013) and/or molecular techniques (Ajani et al. 2013, Momigliano et al. 2013 need to be applied. The latter analyses are u...
