AbstractThe distribution of stream-specific filamentous green algae (SSFG) was investigated in the middle reach of the Tama River, Japan. Cladophora glomerata (L.) Ktzing and Stigeoclonium sp. dominated among five taxa of SSFG collected in the riverbed with fast currents. These two species were abundant in shallow (20cm) riffles with high current velocity (30cms1), a habitat characterized by high...
Abstract Eight cultured strains (OK01, OK02, OK03, OK05, OK07, OK08, OK09, and OK10) of picocyanobacteria were isolated from Lake Okutama. Five cyanobacterial DNA fragments (DGGE bands; B4, B5, B6, B7, and B8) were obtained from the lake water samples by denaturing gradient gel electrophoresis (DGGE) after polymerase chain reaction (PCR) amplification of 16S ribosomal genes. To classify the picocyanobacterial...
