1. Estudo da estrutura da comunidade zooplanctônica e sua relação com as cianobactérias em três reservatórios do médio rio Tietê, SP / Zooplankton structure and its relationships with cyanobacteria in three reservoirs of middle Tietê river, São Paulo State, Brazil
Cyanobacteria blooms are increasingly being detected in São Paulo state reservoirs, particularly in those of middle Tietê river basin. The presence of cyanobacteria can cause deterioration of water quality in these systems due to its potential toxicity to the aquatic biota, and also risks to human health. The aim of the present srtudy was to analyse the st

2. São Paulo in the middle of the marginals: the paulistan image reflectedon the rivers Pinheiros and Tietê / São Paulo no centro das marginais: a imagem paulistana refletida nos Rios Pinheiros e Tietê
The rivers Pinheiros and Tietê have always stood out as a unique landscape on the hilly plateau over which São Paulo has settled. In a process of transformation already begun at the end of the 19th century and whose apex occurred during the 1940s and 1960s decades - when these creeks were channelized and rectified and a pair of urban freeways were built on

3. Estrutura organizacional do fitoplâncton nos sistemas lóticos e lênticos da bacia do Tietê-Jacaré (UGRHi-Tietê-Jacaré) em relação à qualidade da água e estado trófico
The aim of this work was to study the phytoplankton structure of lentic and lotic systems of Tietê/Jacaré basin located in São Paulo State and the relationship between the composition and dominance of phytoplankton organisms with the water quality and trophic state of the rivers and lakes of this basin. The Tietê/Jacare basin is composed by three main ri

5. Toxicity evaluation of Microcystis aeruginosa cultures and natural cyanobacteria blooms from reservoirs of Tietê river, SP / Avaliação da toxicidade de Microcystis aeruginosa e de florações naturais de cianobactérias de reservatórios do rio Tietê, SP
The effects of cyanobacteria upon aquatic organisms were evaluated, aiming to characterize and quantify the toxins of both, a monospecific cyanobacterial culture and material from natural blooms occurring in the reservoirs of Tietê river, SP. The already known toxic strain NPLJ-4 of Microcystis aeruginosa was cultured in ASM-1 medium at 25 Celsius degrees a

6. A comunidade de peixes dos reservatórios dos trechos médio e baixo rio Tietê, com ênfase nas espécies Plagioscion squamosissimus e Geophagus surinamensis. / Fish community of the reservoirs located on middle and low Tietê River, with emphasis in the introduced species Plagioscion squamosissimus and Geophagus surinamensis.
From sixties, the fish species introduction has been being a constant event in the reservoir system located on middle and low Tietê River - SP, which resulted the success introduction of Plagiosicon squamosissimus and Cichla cf. ocellaris in all these reservoirs. According to this context, the present work objectified characterize the fish community, with f

7. A estrutura da comunidade de macro-invertebrados bentônicos em três represas do médio rio Tietê (SP), com ênfase nas espécies exóticas Melanoides tuberculata (Gastropoda, Thiaridae) e Corbicula fluminea (Bivalvia, Corbiculidae).
As represas são ecossistemas artificiais construídos pelo homem e destinadas a múltiplos usos. A condição de represa provoca alterações no ecossistema aquático, causando modificações na composição química e física do sedimento e da água, e conseqüentemente na circulação e na organização das comunidades biológicas. O objetivo deste trabal

8. Analysis of distribution, density and toxicity of cyanobacterial blooms and its toxins in the reservoirs of Middle and Low Tietê river (SP) and its relation with limnological characteristics of this system / Análise da distribuição, densidade e toxicidade de florações de cianobactérias em reservatórios do médio e baixo rio Tietê (SP) e relação com as características limnológicas do sistema
Reservoirs in Brazil, particularly in São Paulo State, are important ecosystems which were built up successively in the last 40 years. Some of these reservoirs, mainly at the Middle and the Low Tietê river cascade system are eutrophic. Frequently cyanobacterial blooms are related to these eutrophic conditions which compromise the multiple use of the reserv

9. Diversidade de avifauna aquática nas represas do médio e baixo Rio Tietê (SP) e nos sistema de lagos do médio Rio Doce (MG) e sua relação com o estado trófico e a morfometria dos ecossistemas aquáticos.
Relationships between aquatic birds and the trophic state of freshwaters are not well known in tropical systems. In the present work the influence of some limnological variables on the structure of the aquatic bird comunnity was investigated for two distinct freshwater systems: The cascade of reservoirs in the middle and low portions of Tietê River (SP) and
