dig-icm-es-10261-2755912022-07-15T06:33:19Z A recurrent and localized dinoflagellate bloom in a Mediterranean beach Garcés, Esther Masó, Mercedes Camp, Jordi 19 pages, 11 figures A recurrent, prolonged and singular bloom of Alexandrium taylori Balech in an open beach (La Fosca, Spain, NW Mediterranean) is described. Alexandrium taylori appears at several places along a wide area of the NW Mediterranean (Costa Brava) during the summer, reaching concentrations up to 105 cells 1-1, but it only proliferates persistently, massively (densities >106 cells 1-1) and recurrently during August in La Fosca beach. The A.taylori bloom can be considered a manifestation of large-scale proliferation in a restricted area, where coupling between resting cysts in the sediment and bloom outbreak is not a major factor compared to the interaction of local environmental conditions with the planktonic organism's life history. From observations of environmental conditions (the environmental window) and the multiscale spatio-temporal distributions and life history of A.taylori, we describe the bloom dynamics and answer some critical questions about the different phases of the bloom. Some of these answers are: (i) the source of the A.taylori population is widespread offshore and is not located directly at the beach; (ii) high cell densities are reached and maintained with a moderate in situ growth and low loss rates; (iii) temporary cysts act as a reserve of the population 2022-07-15T06:25:57Z 2022-07-15T06:25:57Z 1999-12 2022-07-15T06:25:57Z artículo issn: 0142-7873 e-issn: 1464-3774 Journal of Plankton Research 21(12): 2373-2391 (1999) http://hdl.handle.net/10261/275591 10.1093/plankt/21.12.2373 https://doi.org/10.1093/plankt/21.12.2373 Sí none Oxford University Press |
