Última Effects of nutrient impoverishment on phytoplankton biomass: a mesocosms experimental approach in a shallow eutrophic reservoir (Garças Pond), São Paulo, southeast Brazil Rev. Bras. Bot. Crossetti,Luciane O; Bicudo,Carlos E. de M. Nutrient impoverishment in mesocosms was carried out in a shallow eutrophic reservoir aiming to evaluate the nutrient removal technique as a method for eutrophication reduction. Garças Pond is located in the Parque Estadual das Fontes do Ipiranga Biological Reserve situated in the southeast region of the municipality of São Paulo. Three different treatments were designed, each consisting of two enclosures containing 360 liters of water each. Mesocosms were made of polyethylene bags and PVC pipes, and were attached to the lake bottom. Treatment dilutions followed Carlson's trophic state index modified by Toledo and collaborators, constituting the oligotrophic, mesotrophic, and eutrophic treatments. Ten abiotic and 9 biological samplings were carried out... Tipo: Info:eu-repo/semantics/article Palavras-chave: Biomass; Impoverishment; Mesocosms; Phosphorus; Phytoplankton.

Occurrence is reported from the region of the city of São Paulo, southern Brazil, of two euglenoid flagellates (Euglenophyceae). These are very rare, and thus very poorly known members of the class: Scytomonas major (Berliner) Lemmermann and Scytomonas pusilla Stein var. sarmatica Drezepolski. Two species - Gyropaigne brasiliensis C. Bicudo & D. Bicudo, sp. nov. and Phacus ephippioiaeus C. Bicudo & D. Bicudo, sp. nov. - are also described as new to science.

Polymorphism in a population of the desmid (Zygnemaphyceae) Cosmarium abbreviatum Raciborski var. minus (West & West) Krieger & Gerloff is reported from material collected from 3 stations at the Lily Pond located in the Parque Estadual das Fontes do Ipiranga, São Paulo City, southern Brazil. From the examination of approximately 200 plants, 6 different morphological expressions were described and the following remarks made: 1) a detailed analysis of sample populations is absolutely necessary for the definition of species and infraspecific categories among desmids; 2) the morphological characteristics presently used for the delimitation of certain species, which are built up of individuals of very small size, seem to have no great...
