ABSTRACT
The public parks of Goiânia are socioenvironmentally important to the city, however, little is known about their quality and aquatic biodiversity. This study is focused on the Chlorophyceae and Trebouxiophyceae (Chlorophyta) of a lake in an urban park located in the municipality of Goiânia, Goiás State, during a short period of rainfall and drought. Weekly samplings were carried out during August 2007 and January 2008 at three sampling sites, according to the usual techniques for floristic analysis. We identified 25 infrageneric taxa: 16 Sphaeropleales, six Chlorellales, one Chlamydomonales, one Chlorococcales, and one taxon of Trebouxiophyceae of uncertain position. Pandorina morum, Lacunastrum gracillimum, Desmodesmus intermedius var. acutispinus and Pachycladella komarekii represent new records for the State of Goiás.
