| Temporal and spatial variation of Nitella furcata (Roxburgh ex Bruzelius) C. Agardh emend. R.D. Wood subsp. mucronata (A. Braun) R.D. Wood var. mucronata f. oligospira (A. Braun) R.D. Wood were studied at the Ninféias pond (23°38'18.9"S, 46°37'16.3"W), a tropical, shallow, mesotrophic reservoir located in the Parque Estadual das Fontes do Ipiranga Biological Reserve, Municipality of São Paulo, southeast Brazil. Water samples were collected monthly from October/1996 to October/1997 for turbidity, electric conductivity, pH, alkalinity, dissolved oxygen, nutrients, biomass, and algal phenology analysis. Spatial distribution pattern of algal biomass showed that all four sampling stations were similar among themselves during the whole study period. Regarding... |

| The family Characeae, represented by two genera in Brazil, Chara and Nitella, is considered to include the closest living relatives of land plants, and its members play important ecological role in aquatic ecosystems. The present taxonomic survey of Chara and Nitella was performed in tributaries that join to form the Brazilian shore of the Itaipu Reservoir on the Paraná River. Thirteen species were recorded, illustrated, and described: C. braunii var. brasiliensis R.Bicudo, C. guairensis R.Bicudo, N. acuminata A.Braun ex Wallman, N. furcata (Roxburgh ex Bruzileus) C.Agardh, and N. subglomerata A.Braun, already cited for the reservoir, and C. hydropitys Reichenbach, C. rusbyana Howe, N. axillaris A.Braun, N. glaziovii G.Zeller, N. gracilis (Smith) C.Agardh,... |
