Algas E Cianobactérias De Ambientes Extremos Do Pantanal Brasileiro

Abstract: RESUMOAs lagoas alcalinas do Pantanal da Nhecolândia, denominadas "salinas", são exemplos típicos de ambientes extremos por apresentarem elevados valores de pH (˃9). Este estudo mostrou as particularidades da microflora das "salinas" que é composta por espécies alcalíficas tais como Anabaenopsis elenkinii, Anomoeoneis sphaerophora var. sphaerophora e Nitzschia intermedia. Além disso, foi observado que alterações naturais e/ou antrópicas, que permitem a entrada de água doce de sistemas adjacentes às "salinas", … Show more

“…Strain CCIBt 3277 can be considered alkaliphilic, since it grows in an alkaline lake (pH 9–11) in the Brazilian Pantanal wetland region (19° 34′ 32.6″ S 57° 00′ 51.3″ W). This ecosystem, located in the centre of South America, is one of the world's largest wetlands and has hundreds of alkaline lakes (Barbiéro et al , 2002; Malone et al , 2012). The freshwater lake (pH 7–8) where CCIBt 3261 was collected is located in a botanical garden (30° 03′ 2.48″ S 51° 10′ 46″ W) in south-eastern Brazil.…”

“…The stark contrast between diatom assemblages recovered from DZ1 and DZ2 indicates a change of the local hydrodynamics of this system. The disappearance of the planktic species, which are replaced by two benthic diatoms (A. sphaerophora and C. guaykuruorum) capable of living in hyperalkaline, brackish water conditions Malone et al, 2012;Morales et al, 2014), suggests that the lake water may have declined significantly, concomitant with a substantial rise in pH and salinity. These two species are common throughout the modern aquatic environments of the Pantanal region, likely because they are particularly adapted to surviving across a much wider range of environmental conditions, but can become dominant during the dry season .…”

“…Apesar dos numerosos lagos que compõem a planície pantaneira, existem ainda relativamente poucos trabalhos sobre a comunidade fitoplanctônica para o Pantanal Sul, sendo que a maioria dos estudos aborda aspectos estruturais e a influência do pulso de inundação em rios, baías e salinas (Espíndola et al 1996, Oliveira & Calheiros 2000, Domitrovic 2002, Cardoso et al 2012, Malone et al 2012 e apenas um aborda a taxonomia do fitoplâncton (Santos & Sant'Anna 2010).…”
