Resumo
This paper aims to study the composition and some ecological aspects of the phytoplancton of one of
the artificial lakes located at “Chico Mendes” Botanical Garden, Goiânia, Goiás, midwest region of
Brazil. The floristic and some ecological aspects were analised. The samples were collected during
the following periods: dry, begining of the rainy season and rainy. Besides the phytoplancton, some abiot
parameter were mensured (pH, oxygen, temperature, nitrate, nitrite, alkalinity, chlorite, turbity, BDO
e precipitation), 77 taxa belonging to taxonomic classes were recognized and 37 taxa was recorded for
the first time to State of Goiás. Chlorophyceae was the most representative class. During rainy period
the greatest richness was registered, with 11 abundant taxa. In contrast, at the begining of the rainy season
the highest phytoplanktonic density was observed (13,590 ind/ml) with 18 abundant taxa, in special
Nephrochlamys allantoidea (Chlorophyceae) and Phacus dangeardi (Euglenophyceae). The water was
warm (24º-26º), lightly acid through alkalin and meso to oligotrophic.
