Planktic Cyanobacteria from upper Tietê basin reservoirs, SP, Brazil

Abstract: -(Planktic Cyanobacteria from upper Tietê basin reservoirs, SP, Brazil). Considering the great ecological and sanitary importance of the cyanobacteria and the need of detailed information about these organisms in Brazilian water bodies, the present study aims at contributing towards the knowledge of the cyanobacterial flora of five reservoirs belonging to the upper Tietê Basin, São Paulo: Billings, Guarapiranga, Jundiaí, Pirapora, Ponte Nova and Taiaçupeba. In the past several years, these reservoirs have been… Show more

“…Taxonomic characteristics were consistent with taxonomic description for the morphogenus Synechococcus C.Nägeli, 1849, according to Komárek and Anagnostidis (1998). Cells are isolated and rarely form short pseudofilaments; they are cylindrical and straight, without mucilage, 1.5-2 μm long, 1-1.3 μm wide, and without aerotopes (Sant'Anna et al 2007;Komárek and Anagnostidis 1998).…”

“…Komárek & Anagnostidis (2005) comentam que Planktothrix agardhii é uma espécie amplamente distribuída em regiões temperadas com poucos registros em regiões tropicais e ocorre no plâncton de lagos e empoçados de água doce, podendo formar florações. Atualmente, esta espécie é freqüentemente citada como formadora de florações em reservatórios brasileiros (Sant'Anna et al 2007, 2008. Tricomas solitários, retos, geralmente longos, às vezes levemente curvos no ápice, não ou apenas levemente atenuados, levemente constritos; bainha ausente; células mais largas que longas 1,6-4 µm compr., 5,7-7,1 µm larg., Rc/l = 0,3-0,6; conteúdo celular verde azulado, às vezes com pequenos grânulos esparsos; aerótopos irregulares, distribuídos por todo protoplasma; células apicais cilíndrico-arredondadas, não captadas, sem caliptra.…”

“…This morphological plasticity often leads to difficulties in identification, particularly in relation to morphologically and ecologically allied species such as Raphidiopsis mediterranea (McGregor and Fabbro, 2000;Moustaka-Gouni et al, 2009;Alster et al, 2010). R. mediterranea is widely distributed and although generally considered more common in the tropics, it has been reported from Europe (Skuja, 1937;Fré my, 1938;Cronberg, 1973;Hindá k, 1992;MoustakaGouni et al, 2009), Africa (Rao, 1957;Mohamed, 2007), Asia (Li et al, 2008;Namikoshi et al, 2003;Nguyen et al, 2007), North and South America (Nicholls and Carney, 1979;Domitrovic et al, 2007;Sant'anna et al, 2007), New Zealand (Etheridge and Pridmore, 1987), and Australia where it is often a dominant constituent of seasonal phytoplankton blooms in tropical eutrophic reservoirs (McGregor and Fabbro, 2000). Cyanotoxin production has been recorded in a number of different species of Raphidiopsis.…”
