Phytoplankton from the Daimiel National Park. II. Cyanophytes, dinoflagellates, cryptophytes, chrysophytes and xanthophytes
Keywords:Cyanophyta, Dynophyceae, Cryptophyceae, Chrysophyceae, Xanthophyceae, eutrophication, wetland, Castilla-La Mancha
Las Tablas de Daimiel National Park is a semiarid wetland that exhibits a high biodiversity but is suffering an inexorable eutrophication process. The study of the phytoplankton in this wetland is interesting because of its hydrological fluctuations (drought period until 1996) and its trophic condition. This papers shows the taxonomy, dynamic, and ecology of microalgae in five áreas of the Park from 1996 to 1998, which allow comparisons to be made between the present state and the 1992-1993 period. Twelve taxa of Cyanophyta, 4 of Dynophyceae, 8 of Cryptophyceae, 5 of Chrysophyceae and one of Xanthophyceae were found. Almost all species have been already cited in Spain and are typical for eutrophic environments. Cyanophyceae and Cryptophyceae were the most important groups (Planktothrix agardhii, Anabaenopsis elenkinii, Cryptomonas erosa as the most common algae). Moreover, oscillatorial Cyanophyceae (in 1992) have been replaced by N-fixing nostocal ones, related to the high level of pollution found in recent years.
