Variación estacional del género Prorocentrum (Dinophyceae) en dos granjas atuneras en la Bahía de La Paz, México. Acta biol. Colomb. 2015;20(1):195-206. doi: http://dx.doi.org/10.15446/abc.v20n1.42442 RESUMENEl género Prorocentrum Ehrenberg, incluye 81 especies, 21 son consideradas formadoras de florecimientos algales nocivos, de las cuales aproximadamente nueve especies producen toxinas. 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.

Este estudo teve por objetivo identificar as morfo-espécies de dinoflagelados do microplâncton (>20 μm) das Ordens Peridiniales e Prorocentrales ao largo do Cabo de Santa Marta Grande, CSMG (SC, 28º 40' S) e Albardão-Chuí, AC (RS, 34º 40' S) durante dois cruzeiros oceanográficos: inverno de 2005 e verão de 2007. Amostras de plâncton foram coletadas através de arrastos verticais com rede de plâncton (20 μm), preservadas com formalina 4% e analisadas ao microscópio invertido equipado com câmara digital. Quando necessário, a identificação de espécies de Peridiniales foi efetuada através do número e morfologia das placas da teca realçadas com Calco Flúor Branco MR2; espécies de Prorocentrales foram identificadas com base em seu tamanho, forma, presença de processos apicais, padrão dos poros e marcas na faixa intercalar. Foram identificadas 25 espécies, das quais Protoperidinium (11), Prorocentrum (6), Corythodinium (3), Podolampas (2), Oxytoxum (2) e Heterocapsa (1). Espécies de Prorocentrum apresentaram ampla distribuição na plataforma continental do extremo sul do Brasil, enquanto as espécies de Peridiniales foram observadas principalmente na região do Albardão-Chuí durante o inverno, sob a influência da Pluma do Río de la Plata. Oxytoxum milneri foi pela primeira vez registrada na região sul do País, e Protoperidinium cassum var. cassum, P. curtipes e Heterocapsa triquetra foram registradas pela primeira vez no Brasil.

In phytoplankton primary production studies, samples for the determination of photosynthesis versus irradiance relationship ( P -I) are usually incubated at several irradiance levels during a fixed time period, commonly 2 -4 h. However, it is not clear if the use of this fixed incubation time is appropriate to study the P -I relationship in any given ecosystem. The aim of this work was to study the influence of incubation time on the P -I relationship in natural phytoplankton populations from three different coastal ecosystems: an open coastal area, an estuary, and a coastal lagoon. Physical and chemical variables, phytoplankton biomass, species composition, and P -I curves were analysed. The results showed that, in the coastal area and in the estuary, P -I relationships were time dependent, whereas in the coastal lagoon different incubation periods produced the same P -I curve. An underestimation of daily primary production, ranging from 13% to 42.5%, was calculated when data from standard incubation times (2 -4 h) were used in ecosystems where P -I curves present a dynamic time-dependent behaviour. This work suggests that the response of the P -I curves to the incubation time varies with the characteristics of the ecosystem and is related to the light regime to which phytoplankton cells are adapted.
