Algas planctônicas flageladas e cocoides verdes de um lago no Parque Beija-Flor, Goiânia, GO, Brasil

Abstract

-(Planktonic flagellate and coccoid green algae in a lake of Parque Beija-Flor, Goiânia, Goiás State, Brazil). 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.

Periphytic algal flora of the lower Doce river basin after ore tailings flow, Espírito Santo State, Brazil: Sampling design and methods

“…Menezes et al (2015) recorded 4,747 species of algae and cyanobacteria for Brazil. This number is increasing even more with several study efforts, such as the algae flora of streams in the Parnaíba River basin (Auricchio et al 2019), checklist of the Cosmarium in Brazil (Biolo & Bicudo 2018), floristic survey of urban parks (D'alessandro & Nogueira 2017), and descriptions of new species (Ramos et al 2017, Lehmkuhl et al 2019, Ramos et al 2019, Zorzal-Almeida et al 2020. One of the most relevant studies about Brazilian microalgae flora is the survey of the 'Algal Flora of the Parque Estadual das Fontes do Ipiranga (PEFI)', which started in 1962 and registered 869 taxa in 42 fascicles (Bicudo 2020).…”
