| description |
Temporal variations of the phytoplankton of the tributaries and effluent from the C. Gelsi reservoir (Tucumán, Argentina). In this paper we analyzed the phytoplankton variation in the tributaries (Salí, Tapia, and Vipos rivers) and effluent (Salí River) from the C. Gelsi reservoir according to a seasonal gradient. The minimum algal abundance took place in summer with a biomass of 0.19-0.58 µg Cl-a L-1, while the maximum occurred in winter or in spring, with a biomass of 5.43-6.79 µg Cl-a L-1. In the tributaries pennate diatoms prevailed, Diatoma vulgare and Cymbella affinis were most abundant, while in the Salí river (Gelsi effluent) centric diatoms were dominant, particularly Aulacoseira granulata and Cyclotella meneghiniana. Chlorophyta were ranked second in the Salí River, Cyanobacteria codominated in the Vipos and Tapia rivers in March 1998, and Dinophyta could only be seen in the Salí River (Gelsi effluent). The specific diversity index ranged from 0.2 to 4.2 and the saprobic index characterized waters as “non-polluted” or “slightly polluted” in winter, and as “moderately polluted” in summer. The NMDS arranged temporarily the samples according to the abundance of the algal species considered. The RDA showed that the two first axes separated the samples according to gradients of temperature, pH, conductivity, BOD5 and nitrate, and also abundance of Aulacoseira granulata, Cyclotella meneghiniana, Ulnaria ulna, Cymbella affinis and Leptolyngbya foveolarum. |

Phytoplankton algal density biomass, diversity index and saprobic index tributaries and effluent C. Gelsi reservoir Fitoplancton densidad algal biomasa índices de diversidad y sapróbico tributarios y emisario embalse C. Gelsi Temporal variations of the phytoplankton of the tributaries and effluent from the C. Gelsi reservoir (Tucumán, Argentina). In this paper we analyzed the phytoplankton variation in the tributaries (Salí, Tapia, and Vipos rivers) and effluent (Salí River) from the C. Gelsi reservoir according to a seasonal gradient. The minimum algal abundance took place in summer with a biomass of 0.19-0.58 µg Cl-a L-1, while the maximum occurred in winter or in spring, with a biomass of 5.43-6.79 µg Cl-a L-1.

Chlorophyta were ranked second in the Salí River, Cyanobacteria codominated in the Vipos and Tapia rivers in March 1998, and Dinophyta could only be seen in the Salí River (Gelsi effluent). The specific diversity index ranged from 0.2 to 4.2 and the saprobic index characterized waters as “non-polluted” or “slightly polluted” in winter, and as “moderately polluted” in summer. The NMDS arranged temporarily the samples according to the abundance of the algal species considered. The RDA showed that the two first axes separated the samples according to gradients of temperature, pH, conductivity, BOD5 and nitrate, and also abundance of Aulacoseira granulata, Cyclotella meneghiniana, Ulnaria ulna, Cymbella affinis and Leptolyngbya foveolarum. En este trabajo se estudiaron las variaciones temporales del fitoplancton de los tributarios (ríos Salí, Tapia y Vipos) y del emisario (río Salí) del embalse C. Gelsi. La abundancia algal mínima se obtuvo en verano con una biomasa de 0,19-0,58 µg Cl-a L-1 y la máxima en invierno o primavera con una biomasa de 5,43-6,79 µg Cl-a L-1. En los tributarios se destacaron las diatomeas pennadas sobresaliendo Diatoma vulgare y Cymbella affinis y en el río Salí (emisario) dominaron las céntricas especialmente Aulacoseira granulata y Cyclotella meneghiniana. Las Chlorophyta se ubicaron en segundo término en el río Salí, las Cyanobacteria codominaron en los ríos Vipos y Tapia en marzo de 1998 y las Dinophyta sólo fueron observadas en el Salí (emisario). El índice de diversidad específica osciló entre 0,2 y 4,2 y el sapróbico caracterizó las aguas como “no poluídas” o “ligeramente poluídas” en invierno y como “moderadamente poluídas” en verano. El NMDS ordenó temporalmente las muestras según la abundancia de las especies algales consideradas. Los dos primeros ejes del RDA separaron los sitios según gradientes de temperatura, pH, conductividad, DBO5 y nitrato, además de la abundancia de Aulacoseira granulata, Cyclotella meneghiniana, Ulnaria ulna, Cymbella affinis y eptolyngbya foveolarum.
