Spatial-temporal variations of diatom flora in Laguna de Los Pozuelos (Jujuy, Argentina).

Spatial-temporal variations of diatom flora in Laguna de Los Pozuelos (Jujuy, Argentina). Pozuelos shallow lake is located at the northwest of the province of Jujuy (Argentina) at 3625 masl. It was designated as National Natural Monument and Wetland of International Importance (RAMSAR Convention).

Spatial-temporal variations of diatom flora in Laguna de Los Pozuelos (Jujuy, Argentina). Pozuelos shallow lake is located at the northwest of the province of Jujuy (Argentina) at 3625 masl. It was designated as National Natural Monument and Wetland of International Importance (RAMSAR Convention). The aim of this study was to analyze the spatio-temporal variations of the diatom flora in relation to physicochemical variables and species of Phoenicopteridae. Samples were obtained during 4 field-trips between 2008 and 2010. A total of 116 infrageneric taxa were determined. Eighteen species had a frequency of occurrence greater than 50%, 34 were exclusive of the shallow lake, 32 were exclusive of the Cincel River (tributary of the shallow lake) and 39% were observed just once. Species richness was more variable in the shallow lake than in the river. The Redundancy Analysis (RDA) based on physico-chemical data and diatom composition allowed discriminating 3 main groups, which were mainly associated with temperature, salinity and pH. There were 31 new records for this aquatic environment and 18 new records for the province of Jujuy. La Laguna de Los Pozuelos se ubica al noroeste de la provincia de Jujuy (Argentina) a 3625 msnm. Fue designada Monumento Natural Nacional y Humedal de Importancia Internacional (Convención RAMSAR). Este trabajo tuvo como objetivo analizar las variaciones espacio-temporales de la flora de diatomeas y su relación con variables fisicoquímicos y especies de la familia Phoenicopteridae. Se estudiaron muestras recolectadas en 4 campañas entre 2008-2010. Se determinaron un total de 116 taxones infragenéricos. Dieciocho especies tuvieron una frecuencia de ocurrencia superior al 50 %, 34 fueron exclusivas de la laguna, 32 del río Cincel (tributario de la laguna) y un 39 % fue observado una sola vez. La riqueza específica fue más variable en la laguna que en el río. El Análisis de Redundancia (RDA) realizado en base a las variables físico-químicas y composición diatomológica permitió diferenciar 3 grupos principales de especies, que se asociaron principalmente con la temperatura, salinidad y pH. Se registraron por primera vez 31 taxones para la laguna y 18 nuevas citas para la provincia de Jujuy.
