- Abstract
This chapter analyzes space-time variations of phytoplankton in the limnetic zone of the Escaba reservoir and the mouths of its tributary rivers, Chavarría, Las Moras, El Chorro and Singuil, considering physicochemical variables in order to characterize the water quality between 2010 and 2012. One hundred and thirty-five taxa were determined: 77 diatoms, 35 chlorophytes, 12 cyanobacteria, 5 charophytes, 5 euglenoids and 1 dinoflagellate. Algal density varied between 84 and 6,924 individuals/ml with Ceratium hirundinella as the dominant species, except for the spring of 2011. Chlorophyll-a varied seasonally and in space with values between 6 and 2,511 µg/l, with higher numbers for the affluents. Elevated biomass values and the polysaprobic character of the waters defined a deficient or bad ecological status. The specific diversity oscillated between 0 and 2.76. The present study provides new information regarding the algal biodiversity of the Escaba dam and the distribution area of C. hirundinella in the province of Tucumán.
