description The study area ("El Cangrejo Grande", Doñana Natural Park) is located at the final section of the Guadiamar River channel and it is a part of the NE Doñana marshland. The hydrological characteristics of the area are complex and dynamic due to the different origin of its water input: the Guadiamar River basin, the Guadalquivir River estuary, and rice paddies outlets. This area is included in the hydrologic regeneration plan for the Doñana marshland ("Doñana 2005"), though the present study was finished before any modification took place. Phytoplankton richness was high since a total of 224 phytoplankton taxa were registered. Diatoms and Clorophytes were the groups that had the highest richness, Nitzschia palea, Cyclotella atomus and Monoraphidium contortum being the most widely distributed and abundant species. Phytoplankton exhibited a strong seasonal variation, in both composition and biomass, segregated in two periods (flood and desiccation) as suggested by the results of the PCA. On the other hand, the spatial differences were less evident according to a multidimensional scaling analysis (MDS). This seasonal pattern was stronger in the ordination of physico-chemical variables (conductivity, nutrient concentration and suspended matter).We conclude that this system is an ecotone zone with a high hydrologic complexity due to a variety of water inputs with a strong seasonality. These hydrologic features would be the determining factor in phytoplankton composition and high taxon richness.

Las características hidrológicas de la zona son complejas y dinámicas debido a los diferentes aportes que recibe de la cuenca del Guadiamar, del estuario del Guadalquivir y del desagüe de los arrozales. Esta zona está incluida dentro del Plan de Regeneración Hídrica ("Doñana 2005") aunque el presente trabajo finalizó antes de que se llevaran a cabo las actuaciones previstas. La riqueza del fitoplancton fue elevada ya que se registró un total de 224 taxa. Las Diatomeas y las Clorofitas fueron los grupos que reunieron mayor riqueza, siendo Nitzschia palea, Cyclotella atomus y Monoraphidium contortum las especies m'as representativas, en abundancia y distribución. El fitoplancton presentó una fuerte variación estacional, en composición y biomasa, identificándose claramente una dinámica temporal repartida en dos períodos (inundación y estiaje) como sugieren los resultados del análisis de componentes principales. En cambio, las diferencias espaciales fueron menos evidentes como demostró el análisis de ordenación multidimensional no jerárquico (MDS). El patrón estacional fue aún más marcado en el análisis de las principales variables físico-químicas (conductividad, concentración de nutrientes y materia en suspensión). Se concluye que este sistema corresponde a una zona de ecotono de gran complejidad hidrológica debido a la existencia de una variedad de aportes hídricos sujetos a variaciones estacionales; esta complejidad sería el factor determinante de la composición y elevada riqueza del fitoplancton. 22007-01-0120072007-01-01Articlehttp://purl.org/coar/resource_type/c_6501VoRhttp://purl.org/coar/version/c_970fb48d4fbd8a85info:eu-repo/semantics/articleapplication/pdfhttps://ddd.uab.cat/record/27981reponame:Dipòsit Digital de Documents de la UABinstname:Universitat Autònoma de BarcelonaInglésengopen accesshttp://purl.org/coar/access_right/c_abf2Aquest material està protegit per drets d'autor i/o drets afins.
