Phytoplankton abundance at 2 lagoons in Doñana LTSER Platform (2011-2012)

Annual vascular plant percent cover measured per species along 3 15m long transects inside 15x15m2 plots. 21 plots are placed in the dominant shrubland communities in Doñana Biological Reserve inside the Doñana LTSER Platform. Abundance may directly be estimated from percent cover. Species list is indicated listcode field. (Spatial Scale Description: Water samples were collected at the point of maximum depth of the lake by means of a Ruttner bottle. Samples were collected at the following depths: 0, -2 m, -6 m, -10 m, -14 m, -18 m, bottom. Samples were kept refrigerated and transported to the laboratory where nitrate concentrations were determined spectrophotometrically by means of the Sodium Salicylate Method (Rodier, 1978). Samples were collected monthly from june to october.)
