Title A name given to the resource Determination of eutrophic areas in Mundaú/Manguaba lagoons, Alagoas-Brazil, through studies of the phytoplanktonic community Determinação de áreas eutróficas nas lagoas Mundaú e Manguaba, Alagoas-Brasil, através de estudos com a comunidade fitoplanctônica Creator An entity primarily responsible for making the resource EM. Melo-Magalhães, PRP. Medeiros, MCA. Lira, ML. Koening, AN. Moura Description An account of the resource Mundaú and Manguaba Lagoons (9° 34' 38'-9° 45' 30' S and 35° 44' 00'-35° 58' 13' W) are considered the largest and most productive ones in the state of Alagoas and were studied with the purpose of identifying the existence of anthropic impacts. Samples were collected at 8 stations, during low tide and flooding in rainy and dry periods, using the 'Van Dorn' bottle and plankton net. In total, 155 taxons were identified, with special emphasis on Bacillariophyta and Cyanophyta divisions. The most abundant species in Mundaú Lagoon was Skeletonema cf. costatum, and in the Manguaba Lagoon, Cyclotella meneghiniana, Microcystis aeruginosa and Anabaena spiroides. The diversity ranged from 0.17 bits cell/L to 4.81 bits cell/L. The predominance of freshwater species (51%), evidenced higher influence of the limnetic flow on the two environments studied. The high values related to the phytoplanktonic density characterize the lagoons as strongly impacted environments, indicating the existence of eutrophic conditions in most of the studied stations.As lagunas Mundaú e Manguaba (9° 34' 38'-9° 45' 30' S e 35° 44' 00'-35° 58' 13' W) são consideradas as maiores e mais produtivas do Estado de Alagoas e foram estudadas com o objetivo de identificar a existência de impactos antrópicos, nos períodos chuvoso e seco, com base na composição, diversidade e densidade fitoplanctônica. Coletas de material fitoplanctônico foram realizadas em 8 estações fixas, durante maré vazante e enchente nos períodos chuvoso e seco. As amostras foram coletadas com garrafa de 'Van Dorn' e rede de plâncton. Foram identificados 155 táxons destacando-se as divisões Bacillariophyta e Cyanophyta. A espécie mais abundante na laguna Mundaú foi Skeletonema cf. costatum; na laguna Manguaba foram Cyclotella meneghiniana, Microcystis aeruginosa e Anabaena spiroides. A diversidade oscilou ente 0,17 bits cell/L e 4,81 bits cell/L. A predominância de espécies dulciaquícolas, (51%) evidenciou maior influência do fluxo limnético nos dois ambientes estudados. Os altos valores da densidade fitoplanctônica caracterizam as lagunas como ambientes fortemente impactados, indicando a existência de condições eutróficas na maioria das estações estudadas.
