“…From 33 new records, nine species were non planktonic, specially belong to Collothecidae in Torto branch of the lake. This fact confirms the importance to increase the sampling effort in order to cover the diversity spectrum present in aquatic ecosystems, as discussed by Starling (2000) for central Brazil. …”

This study examined rotifers from Lake Paranoá, an urban reservoir of central Brazil, within an exploratory sampling (from 1996 to 2005) on littoral and deeper areas in the lake and from the mouth of the tributaries of the lake (Torto and Bananal - north part, Gama and Riacho Fundo - south part) and registered five genera and 33 species are new records for the reservoir. This reservoir was subject to intense eutrophication at least during thirty years (1960 to 1998). Since 1999, when the lake underwent intentional flushing, shifts in species composition of rotifers were identified. Four new records were exclusives in triburary of Lake Paranoá. An expressive number of non planktonic species were registered in pelagic zone of Lake Paranoá, specially belong to Collothecidae.

“…A alta freqüência destas espécies confirma a grande importância destes rotíferos no zooplâncton de águas continentais tropicais. Keratella tropica é uma espécie planctônica tropical (Dábes 1995, Starling 2000, Duggan et al 2001 ambos dados não publicados). Almeida (2005), através de revisão de literatura, também cita a presença desta espécie em ecossistemas lênticos dos estados do Ceará, Paraíba, Minas Gerais e São Paulo.…”

The state of the art in planktonic rotifers biodiversity from some freshwater ecosystems was elaborated for the state of Pernambuco (Brazil). A bibliographic survey was done and most studies focused seasonal aspects and trophic state of the ecosystems. At least 19 continental aquatic environments related to rotifer researches have been studied. The Sertão area was the most studied. The present survey registered 64 species of planktonic rotifers, distributed in 18 families and 29 genera. The most frequent species were Keratella tropica and Brachionus falcatus, showing that most studies were done in the limnetic zone. The results showed the need for more research on the biodiversity of this group in ecosystems located in Zona da Mata and Agreste areas, as well as in lotic systems and in the littoral zones, in view of the lack of information.Keywords: Rotifera, check-list, limnic ecosystems, Pernambuco, northeast Brazil.

Um levantamento bibliográfico foi realizado e a maior parte das pesquisas enfocou aspectos sazonais e estado trófico dos ecossistemas. Pelo menos 19 locais foram estudados no tocante aos rotíferos. O Sertão é a região mais estudada. Nesta pesquisa foram registradas 64 espécies de rotíferos planctônicos, distribuídas em 18 famílias e 29 gêneros. As espécies mais freqüentes nos locais estudados foram Keratella tropica e Brachionus falcatus, mostrando que a maior parte dos estudos foi realizada na zona limnética. Os resultados sugerem ainda a necessidade de mais pesquisas sobre a biodiversidade deste grupo em locais localizados na Zona da Mata e no Agreste, bem como em ecossistemas lóticos e nas zonas litorâneas dos locais, tendo em vista a carência de informações.

“…For example, according to Paturej (2008) the Shannon-Weaver index of species diversity, for the whole zooplankton community, tends to decrease as a water body becomes more eutrophic. In central Brazil, one comparative study of the zooplankton composition of six lacustrine ecosystems, observed a tendency of decreasing diversity with increasing trophic level (Starling, 2000). In China, Xiong et al (2003), in their study with plankton community, conducted in four Chinese lakes of different trophic states, concluded that species number was negatively correlated with degree of water eutrophication.…”

ABSTRACT. Planktonic rotifers and cyclopoid copepods were studied in two reservoirs of different trophic states (eutrophic and oligo/mesoeutrophic) in the south of Brazil. During a year, monthly samplings were carried out in three stations in each reservoir. Species richness, frequency and abundance were used to find out useful and indicatives trends of water quality based on these organisms, reinforced by literature data. Species that showed higher differences between reservoirs were chosen. For Rotifera, richness, frequency and abundance of Brachionus were higher in the eutrophic reservoir, but Plationus patulus occurred only in the oligo/mesotrophic reservoir. For copepods, Tropocyclops prasinus dominated in the eutrophic reservoir, but Thermocyclops decipiens, T. minutus, T. inversus and Microcyclops anceps were dominants in the oligo/mesotrophic reservoir. In the canonical correspondence analysis, these species were indicators of the trophic state and were related with chlorophyll-a, total phytoplankton and total phosphorus. The use of these species can be efficient in the studied regions (subtropical/temperate), but comparing with other Brazilian reservoirs of tropical climate, the results could be different. Despite the dominance of T. decipiens over T. minutus, T. inversus has been widely used in Brazil as an indicator of eutrophic waters; in those cases of excessive eutrophication, other species, more rustic, commonly dominate. In the present study, Thermocyclops was dominant in the oligo/mesotrophic reservoir. The dominance of Brachionus for rotifers and Tropocyclops prasinus and Acanthocyclops robustus for copepods were indicative of eutrophic conditions. Keywords: abundance, bioindicators, diversity, evenness, species richness, Brazil.Relaciones entre los rotíferos, copépodos planctónicos ciclopoides y la calidad del agua en dos embalses brasileños RESUMEN. Se analizaron los rotíferos y copépodos planctónicos ciclopoides colectados en dos embalses de diferentes estados tróficos (eutróficos y oligo/mesoeutróficos) en el sur de Brasil. Durante un año, se efectuaron muestreos mensuales, en tres estaciones en cada embalse. La riqueza de especies, frecuencia y abundancia, se utilizó para determinar tendencias útiles e indicativas de la calidad del agua sobre la base de estos organismos, complementando con datos de la literatura. Se escogieron aquellas especies que presentaron las mayores diferencias. Para rotíferos, la riqueza, frecuencia y abundancia de Brachionus fueron más altas en el embalse eutrófico, Plationus patulus se detectó sólo en el embalse oligo/mesotrófico. Para los copépodos, Tropocyclops prasinus dominó en el embalse eutrófico, mientras que Thermocyclops decipiens, T. minutus, T. inversus y Microcyclops anceps dominaron en el embalse oligo/mesotrófico. En el análisis de correspondencia canónica, estas especies fueron indicadoras del estado trófico y se relacionaron con la clorofila-a, fitoplancton total y fósforo total. El uso de estas especies puede ser eficaz en las regiones estudiadas ...
