Temporal variation of the phytoplankton community at short sampling intervals in the Mundaú reservoir, Northeastern Brazil

Abstract: RESUMO -(Variação temporal da comunidade fitoplanctônica em curtos intervalos amostrais no reservatório de Mundaú, Nordeste brasileiro). O objetivo deste estudo foi detectar a influência dos fatores abióticos sobre a comunidade fitoplanctônica em um reservatório de abastecimento, em curtos intervalos amostrais. As amostras foram coletadas na subsuperfície (0,1 m) e fundo das regiões pelágica (8 m) e litorânea (2 m), durante dois períodos sazonais, estações seca e chuvosa. As variáveis abióticas analisadas fora… Show more

“…In addition, some studies have observed an increase in phytoplankton density and biomass due to the selective consumption of the zooplankton and consequent dominance of Cyanobacteria (Degans and Meester, 2002;Kozak and Goldin, 2004;Borges et al, 2010). Cyanobacteria and Chlorophyceae were particularly represented by Chroococcales and Chlorococcales, respectively, especially colonial nanoplanktonics, that presented high surface/volume ratio, which increases the absorption of nutrients allowing adaptive advantages (Lopes et al, 2005;Dantas et al, 2008;Brasil and Huszar, 2011).…”

“…Condições de estratifi cação ou mistura completa da coluna de água foram determinantes para favorecer diferentes agrupamentos em um lago eutrófi co na Alemanha (Wilhelm & Adrian 2008) e em três reservatórios australianos (Burford & O'Donohue 2006). Diversos outros estudos investigaram a distribuição relativa dos grupos e os fatores abióticos e bióticos intervenientes (Huszar & Caraco 1998, Salmaso 2002, Willén 2003, Padisák et al 2006, Zhang et al 2007, Dantas et al 2008, Sarmento & Descy 2008.…”

“…The most important functional groups found in the summer period (F and K) are generally related to shallow nutrient-rich water columns with good light availability and higher temperatures (Huszar et al, 2000;Komárek, 2003;Sant'Anna et al, 2006). These groups have been frequently reported as dominants in tropical shallow lakes and reservoirs, usually favored by the stability of the water column, light and nutrients availability Silva et al, 2005;Moura et al, 2007;Dantas et al, 2008;Crossetti et al, 2013).…”
