DENOMINACIÓN DEL PROYECTO: AMBIENTES ACUÁTICOS CONTINENTALES Y COSTEROS DE ARGENTINA: PRINCIPALES VARIABLES FISICO-QUÍMICAS Y BIÓTICAS VINCULADAS CON LA CALIDAD DEL AGUA.

Resumen:
Se continuará con la investigación iniciada en 2003 a fin de evaluar la calidad del agua en ambientes continentales y costeros de Argentina, mediante el análisis de
Palabras claves: bacterias – microfitobentos – aguas continentales y costeras – calidad del agua.parámetros físicos, químicos y bióticos. En relación al microfitobentos, una vez caracterizada la estructura de la comunidad a lo largo de un ciclo anual en la Laguna de Los Padres (EXA 582/12), y estudiado el proceso de colonización por parte de las algas epipélicas mediante el uso de sustratos artificiales (EXA 673/14) se evaluará, mediante un experimento in situ, el efecto del sombreado provocado por la vegetación acuática sobre dichas algas. Con respecto a ambientes costeros, una vez determinada la calidad bacteriológica del agua para uso recreacional de la zona adyacente a la Planta de Tratamiento de Efluentes Cloacales de la ciudad de Mar del Plata, previa a la instalación del Emisario Submarino (EXA 582/12), y dado que en el proyecto en curso (EXA 673/14) no pudo cumplirse con el cronograma establecido, debido a la dilación en la puesta en marcha de dicho Emisario, se propone concretar el monitoreo bacteriológico en el período de verano 2016 y 2017. Se llevará a cabo esta investigación proponiendo un marco comparativo dentro de la limnología regional.
TITULO DEL PROYECTO EN INGLÉS: FRESHWATER AND COASTAL ECOSYSTEMS FROM ARGENTINA: THEIR MAIN PHYSICAL, CHEMICAL AND BIOTIC PARAMETERS RELATED TO WATER QUALITY.
Abstract:
The present research will continue those begun in 2003 with the purpose of evaluating the water quality of continental and coastal environments from Argentina by means of the estimation of physical, chemical and biotic parameters. As microphytobenthos concerns, after characterizing its community structure at Los Padres Lake during an annual cycle (EXA 582/12), and studied the epipelic algal colonization using artificial substrates (EXA 673/14), the effect of shading produced by macrophytes over these algae will be evaluated by means of an in situ experiment. Related to coastal environments, given that bacteriological analyses from recreational waters near the Treatment Plant of Mar del Plata sewage effluents were carried out before the installation of the Submarine Emissary (EXA 582/12), and that during the present project (EXA 673/14) the designed activities could not be performed, because of the delay in the star
t up of the emissary, it is proposed to carry out the bacteriological monitoring during summer 2016 and 2017. It is of our concern to carry out this research proposing a comparative framework within the regional limnology.
Key words: bacteria – microphytobenthos – continental and coastal waters – water quality.
