The algaes may occour in various environments on the planet, and have variated
life habits and have different living habits among which we can highlight the
planktonic and periphyton communities.The aim of this study was to identify the
community of planktonic algae in the affluent Bate Estacas, located in Porto
Velho, Rondônia. The collections occur at September, October and November
2010 at two stations georeferenced, E1: 8º47'32.89"S 63º55'15.41"O; e E2: 8º48'20.03 65º55'48.74"O. Were collected 80L of water, soon after were filtered
on a plankton network with mesh size of 25μm. The samples were fixed in
transeau solution. The species identification was performed in an optical
microscope, with literature for each algal group. As results were identified 29
species in five divisions, 6 classes, 8 orders and 11 families. Division Chlorophyta
showed 10 species, appear as the richest group. The species of Chlorophyta:
Treubaria triapendiculata; Scenedesmus acuminatus; Scenedesmus arcuatus;
Ankistrodesmus sp; Pediastrum tetras; Dictyosphaerium sp; Desmodesmus sp;
Acathosphaera sp; Pediastrum duplex; Pediastrum simplex. The division
Streptophyta with 8 species: Micrasterias borgei var. multidentata; Micrasterias
mahabuleshwarensis var. mahabuleshwarensis; Staurastrum sp; Staurastrum
margaritaceum var. margaritaceum; Closterium sp; Closteriopsis ongíssima var.
tropica; Closterium rostratum; Staurastrum glodiosum. Were also identified seven
species of algae flagellated, Euglenophytas: Lepocinclis ovata; Lepocinclis salina
var. salina; Trachelomonas sydneyensis; Phacus triqueter; Phacus longicauda;
Strombomonas scabra; Euglena sp.Divisions with less frequent were
Bacillariophyta and Cianophytas with 2 species respectively Surirella sp;
Pinnularia cardinalis, Oscillatoria princips, Microcystis sp. The present study
expanded the knowledge of planktonic algae from the state of Rondônia.
