Resumen
El objetivo de este trabajo fue aportar al conocimiento de las cianobacterias de humedales de altura del Noroeste Argentino (NOA). Se realizó un muestreo interdisciplinario del 21 de enero al 01 de febrero de 2005 que abarcó el censo de veintiséis lagunas correspondientes a las provincias de Jujuy, Salta y Catamarca. Las muestras cualitativas se obtuvieron mediante el filtrado de 25 litros de agua a través de una red de plancton de 20 µm de poro. Las mismas fueron fijadas “in situ” y observadas bajo microscopio binocular con dispositivo para dibujo. De acuerdo a los resultados obtenidos la taxocenosis estuvo integrada por 23 taxones, en su mayoría cosmopolitas y de medios salobres, pertenecientes a Chroococcales (5), Nostocales (3) y Oscillatoriales (15). Se citan por primera vez doce especies para Catamarca, de las cuales sólo una es un nuevo registro para el NOA.
The objective of this paper was to contribute to knowledge of Cyanobacteria of High Wetlands from Nor thwest of Argentina. An interdisciplinary sampling was realized from 21 on January to 01 on February and twentisix lakes were studied corresponding to Jujuy, Salta and Catamarca provences. The qualitative samples were collected with plankton net of 20 µm and filtering of 25 litres of water. These samples were fixed in situ and observed with binocular microscopy and drawing camera in laboratory. According of results obtained the taxocenoses was formed by 23 taxa specially cosmopolites and brackish environments belong to Chroococcales (5), Nostocales (3) and Oscillatoriales (15). We described for the first time twelves species to province of Catamarca and just one for the northwestern to Argentina.
