Colonización del Lago de la Casa de Campo (Madrid) por el fitoplancton
Abstract
The Casa de Campo Lago was dessicated in 2018 and its phytoplankton colonization was studied over an annual cycle after its reflooding at the beginning of the next year, along with factors controlling its dynamics. The more frequent phytoplankton morphotype in early colonization was that of flagellates, with taxa richness being roughly constant, but overall biomass remained low. From June onwards, both biomass and richness steeply increased, being dominated by chlorococcalean green algae and Cyanophytes. Dissolved organic carbon and organic nitrogen were the main physico-chemical factors controlling biomass. The scanty data available from other years suggested that zooplankton was negligible as control factor for phytoplankton. The main source for phytoplankton colonization was the Valchico wetland, and that process seemingly took place by duck zoochory.
