“…During 2005-2009, the maximum abundance of N. scintillans reached 550,000 ind. m 2 and was close to the magnitudes reported by Yılmaz et al (2005). According to our data, the maximum abundance of this species were recorded in five samples from the southern Bosphorus area and in three samples collected near the Prince Islands.…”

“…Near the Bosphorus Strait in the Marmara Sea, N. scintillans dominated in abundance and biomass among other mesozooplankton species (Yuksek et al 2003;Yılmaz et al 2005). According to Isinibilir et al (2011), copepods constitute 79-93% of mesozooplankton in this region, with Acartia clausi Giesbrecht, 1889 being the most abundant species (Benli et al 2001).…”

“…High mortality of copepods in the Marmara Sea near the Bosphorus area (calculated to be 0.69 d −1 , see Isinibilir et al 2011) can significantly contribute to the concentration of organic matter in this region. Morever, in the highly polluted areas of the Marmara Sea, the heterotrophic dinoflagellate N. scintillans can develop successfully (Koval 1984;Yılmaz et al 2005;Zaika 2005;Pavlova & Melnikova 2006), consuming A. clausi eggs (Daan 1987;Quevedo et al 1999). Thus, determining the mutual effects between A. clausi and N. scintillans populations may contribute to improving our understanding of the functioning of zooplankton communities in the adjacent areas of the Black and Marmara Seas.…”

The dynamics of abundance and biomass of Noctiluca scintillans (Dinoflagellata) and Acartia clausi (Copepoda) in the Bosphorus area of the Black and Marmara Seas during 2005-2009 has been analyzed. Despite the fact that the more abundant Black Sea zooplankton community permanently enters the Marmara Sea, A. clausi and N. scintillans have formed independent populations in the northeast of the Marmara Sea. This may be confirmed on the one hand by the positive correlations between the numbers of A. clausi and N. scintillans individuals in the Marmara Sea near the Bosphorus Strait and near the Prince Islands and, on the other hand, by a lack of correlation between the abundance of these species in the Marmara Sea and in the Bosphorus area of the Black Sea. The abundance of N. scintillans was 6-10 times lower in the Black Sea near the Bosphorus Strait than that in the Marmara Sea. A high correlation (r = 0.84) between the abundance of N. scintillans and the number of dead A. clausi females near the Bosphorus Strait in the Marmara Sea suggests an important role of necrozooplankton in the development of the dinoflagellate.

“…Las tasas de ingesta en el presente estudio fueron relativamente altas; sin embargo, hasta donde sabemos, no existen trabajos sobre la ingesta de N. scintillans sobre G. catenatum, por lo que la comparación realizada anteriormente debe tomarse con precaución. De acuerdo con Yilmaz et al (2005), N. scintillans tiene una estrategia de alimentación oportunista tipo r. Esta estrategia es evidente en este trabajo, sugerida por las altas tasas de consumo mostradas. Bajo condiciones naturales, se han observado hasta 18 huevos de A. clausi (Quevedo et al 1999) o 27 huevos de copépodos (Daan 1987) ) en los diferentes periodos de incubación (1, 2, 3 y 5 días) (ND = no determinado).…”

“…Direct comparisons with other studies, including those mentioned here, are only suggestive. Noctiluca scintillans is a successful r-strategist, with its opportunistic feeding behavior (Yilmaz et al 2005); its high predation capacity is evident from its high ingestion rates. Under natural conditions, up to 18 A. clausi eggs (Quevedo et al 1999) or 27 copepod eggs have been observed in a single N. scintillans cell (Daan 1987).…”

ABSTRACT. Temperature and nutrient concentrations were measured during a mixed bloom of Noctiluca scintillans and Gymnodinium catenatum in La Paz Bay, Gulf of California. Under laboratory conditions, we offered three concentrations of G. catenatum (312, 625, or 1015 cells mL -1 ) to 0.53 N. scintillans cells mL -1 to study predation rates. Experiments were carried out with 750 mL of culture during a fiveday period. Sea surface temperature clearly showed a transitional period from colder to warmer water during the bloom. RESUMEN. Se monitoreó la temperatura y los nutrientes durante una proliferación de Noctiluca scintillans y Gymnodinium catenatum en la bahía de La Paz, golfo de California. También, bajo condiciones de laboratorio, se mezclaron diferentes concentraciones de G. catenatum (312, 625, o 1015 células mL -1 ) con 0.53 células de N. scintillans mL -1 a fin de evaluar las tasas de pastoreo. La experimentación se llevó a cabo en 750 mL de cultivo durante un periodo de cinco días. La temperatura superficial mostró claramente un periodo de transición de agua fría a caliente durante la proliferación. Las observaciones de campo y las de laboratorio mostraron que N. scintillans se alimentaba de G. catenatum. En el laboratorio, más del 70% de N. scintillans contenía células de G. catenatum en sus vacuolas. La tasas de ingestión variaron ampliamente; los valores más altos variaron de 30 a 40 células de G. catenatum h -1 en cada célula de N. scintillans. No se observó una relación entre las diferentes concentraciones de G. catenatum ofrecidas y la tasa de ingestión. Al final del experimento se observaron tasas de ingestión bajas de 1 a 3 células de G. catenatum h -1 en cada célula de N. scintillans. La concentración de N. scintillans se duplicó aproximadamente cada 48 h; sin embargo, observamos numerosos trofontes saliendo de su cubierta externa, lo cual sugiere que existió daño celular. Estos datos indican que N. scintillans ingiere a G. catenatum pero la presa parece dañar al depredador en un corto plazo.Palabras clave: Gymnodinium catenatum, Noctiluca scintillans, pastoreo, biocontrol, bahía de La Paz.

The globally distributed heterotrophic dinoflagellate Noctiluca scintillans (Macartney) Kofoid & Swezy is well known for its dense blooms and prominent displays of bioluminescence. Intriguingly, along the west coast of the U.S.A., its blooms are not bioluminescent. We investigated the basis for this regional loss of bioluminescence using molecular, cellular, and biochemical analyses of isolates from different geographic regions. Several prominent differences were identified in the nonbioluminescent strains: (1) the fused luciferase and luciferin binding protein gene (lcf/lbp) was present but its transcripts were undetectable; (2) lcf/lbp contained multiple potentially deleterious mutations; (3) the substrate luciferin was absent, based on the lack of luciferin blue autofluorescence and the absence of luciferin‐derived metabolites; (4) although the cells possessed scintillons, the organelles that contain the luminescent chemistry, electron microscopy revealed additional scintillon‐like organelles with an atypical internal structure; and (5) cells isolated from the California coast were 43% smaller than bioluminescent cells from the Gulf of Mexico. Phylogenetic analyses based on large subunit rDNA did not show divergence of the nonbioluminescent population in relation to bioluminescent N. scintillans from the Pacific Ocean and Arabian Sea. This study demonstrates that gene silencing and the lack of the luciferin substrate have resulted in the loss of an important dinoflagellate functional trait over large spatial scales in the ocean. As the bioluminescence system of dinoflagellates is well characterized, nonbioluminescent N. scintillans provide an ideal model to explore the evolutionary and ecological mechanisms that lead to intraspecific functional divergence in natural dinoflagellate populations.
