Epilithic phycoflora and environmental variables of Calimayo Stream (Tucumán Argentina).

Epilithic phycoflora and environmental variables of Calimayo Stream (Tucumán-Argentina). Tucumán is known for its richness in natural and water resources. Previous phycological studies focused mainly on the phytoplankton, but little was done in relation to the epilithic phycoflora. The aim of this r...

description Epilithic phycoflora and environmental variables of Calimayo Stream (Tucumán-Argentina). Tucumán is known for its richness in natural and water resources. Previous phycological studies focused mainly on the phytoplankton, but little was done in relation to the epilithic phycoflora. The aim of this research was to analyze the epilithic taxocenosis and physicochemical variables of Calimayo stream during an annual cycle, and to contribute to the taxonomic knowledge of the phycoflora in Northwestern Argentina. Physicochemical and biological samples collected in 2012-2013 were studied. The water was alkaline, bicarbonate-calcium, oligosaprobic in summer/13 and oligo-?-mesosaprobic in the other seasons. Mineralization was average and the stream was well oxygenated. The Bacillariohyceae class presented 69 taxa followed by Divisions Cyanophyta (10), Chlorophyta (5) and Rhodophyta (1). The following species were always present: Amphipleura lindheimerii, Cocconeis placentula var. lineata, Cymbella affinis, Gomphonema olivaceum, G. parvulum, Luticola mutica, Navicula tripunctata, Nitzschia palea, Orthoseira roeseana, Planothidium frequentissimum, P. lanceolatum, Reimeria uniseriata, Rhoicosphenia abbreviata, Ulnaria ulna, Oedogonium sp., Lyngbya sp. 1, Myxosarcina spectabilis, Oscillatoria sp. 1 y 2. Of a total of 85 taxa, 70 are cited for the first time for epilithon and Myxosarcina spectabilis is a new record for Tucuman. Phycoflora composition was influenced by temperature, depth, precipitation and pH.

Phycoflora composition was influenced by temperature, depth, precipitation and pH. Tucumán se destaca por sus riquezas en recursos naturales e hídricos. Los estudios ficológicos se basaron principalmente en el fitoplancton, siendo escaso el análisis de la ficoflora epilítica. Los objetivos fueron analizar la taxocenosis epilítica y variables fisicoquímicas del arroyo durante un ciclo anual y contribuir al conocimiento de la ficoflora del NOA. Se estudiaron muestras fisicoquímicas y biológicas recolectadas durante 2012-2013. El agua tuvo un pH alcalino, se caracterizó como bicarbonatada-cálcica, oligosapróbica (verano/13) y oligo-?-mesosapróbica en las otras estaciones. La mineralización fue media y el arroyo estuvo bien oxigenado. La Clase Bacillariohyceae presentó 69 taxones seguida de las Divisiones Cyanophyta (10), Chlorophyta (5) y Rhodophyta (1). Las especies siempre presentes fueron: Amphipleura lindheimerii, Cocconeis placentula var. lineata, Cymbella affinis, Gomphonema olivaceum, G. parvulum, Luticola mutica, Navicula tripunctata, Nitzschia palea, Orthoseira roeseana, Planothidium lanceolatum, P. frequentissimum, Reimeria uniseriata, Rhoicosphenia abbreviata, Ulnaria ulna, Oedogonium sp., Lyngbya sp.1, Myxosarcina spectabilis, Oscillatoria sp. 1 y 2. Las mayores densidades se presentaron en época invernal. De un total de 85 taxones, 70 se citan por primera vez para el epiliton y Myxosarcina spectabilis es un nuevo registro para Tucumán. La composición de la ficoflora estuvo influenciada por: temperatura, profundidad, precipitaciones y pH.
