Resumo: | The aim of the present study was to analyze the phytoplankton in the Arcoverde-PE reservoir, during the nictemeral cycle in two distinct seasonal periods. Collections were made at two depths during the rainy and dry periods in 2007. The phytoplankton was identified and the density determinated. Concomitantly, analyses were carried out for the characterization of the system. In the rainy season, water was oxygenated, neutral pH, turbid and warmer, and in the dry season, the water ranged to oxygenated to anoxic, alkaline pH and turbity at surface. In both seasons, there was limited nitrogen and high concentrations of phosphorus. Thirtyeight infraspecific taxa were identified. Chlorophyta and Cyanophyta had the greatest number of species. Cyanophyta generally had higher densities in both seasons, at both depths and at different hours. It was observed a perennial bloom of Cylindrospermospis raciborskii. There was significant variations among hours and depths for abiotic variables in both season and it was observed significant differences for densities of phytoplankton for seasonal analysis. This indicates that environmental changes in the concentration of nutrients, pH and turbidity of the water are factors that facilitate the occurrence of Cyanophyta. |

As coletas foram feitas em duas profundidades durante os períodos chuvoso e de estiagem de 2007. O fitoplâncton foi identificado e a densidade determinada. Concomitantemente, foram feitas análises para caracterização do sistema. No período chuvoso, a água apresentou-se oxigenada com pH neutro, túrbida e quente, e no de estiagem, a água variou de oxigenada a anoxia, com pH alcalino e túrbida na superfície. Nos dois períodos sazonais, foi verificada limitação de nitrogênio e elevadas concentrações de fósforo. Foram identificados 38 táxons infraespecíficos. Chlorophyta e Cyanophyta apresentaram maior número de espécies. Cyanophyta apresentou geralmente densidades mais elevadas nos dois períodos sazonais, profundidades e horários. Foi registrada floração perene de Cylindrospermopsis raciborskii no reservatório Arcoverde. Foram observadas variações significativas entre as horas e profundidades para as variáveis abióticas em ambos períodos. Foram observadas diferenças significantes para a densidade do fitoplâncton na análise sazonal, indicando que as mudanças ambientais nas concentrações de nutrientes, pH e turbidez da água são fatores facilitadores para a ocorrência de Cyanophyta.Submitted by (edna.saturno@ufrpe.br) on 2016-07-04T14:44:51Z No. of bitstreams: 1 Silvana Nascimento Dias.pdf: 373686 bytes, checksum: 1c793719a2a13c176eacc86d53d32a54 (MD5)Made available in DSpace on 2016-07-04T14:44:51Z (GMT).

The aim of the present study was to analyze the phytoplankton in the Arcoverde-PE reservoir, during the nictemeral cycle in two distinct seasonal periods. Collections were made at two depths during the rainy and dry periods in 2007. The phytoplankton was identified and the density determinated. Concomitantly, analyses were carried out for the characterization of the system. In the rainy season, water was oxygenated, neutral pH, turbid and warmer, and in the dry season, the water ranged to oxygenated to anoxic, alkaline pH and turbity at surface. In both seasons, there was limited nitrogen and high concentrations of phosphorus. Thirtyeight infraspecific taxa were identified. Chlorophyta and Cyanophyta had the greatest number of species. Cyanophyta generally had higher densities in both seasons, at both depths and at different hours. It was observed a perennial bloom of Cylindrospermospis raciborskii. There was significant variations among hours and depths for abiotic variables in both season and it was observed significant differences for densities of phytoplankton for seasonal analysis. This indicates that environmental changes in the concentration of nutrients, pH and turbidity of the water are factors that facilitate the occurrence of Cyanophyta. |
