Algae are a common component of freshwater ecosystems. The presence and abundance of these organisms has often been used as an indicator of water quality. In addition, algae such as Enteromorpha are able to accumulate pollutants, and have been used to monitor toxic trace metal pollution in aquatic environments [l]. In marine algae, heavy metal pollution has been shown to affect acyl-lipid compo...

The seasonal and spatial dynamics of two groups of macroalgae, drift algae and rhizophytes, commonly found in tropical seagrass meadows were studied. The aim of this study was to provide insight into how freshwater discharges may be altering seagrass-dominated nearshore tropical habitats. Species composition, biomass, and percent cover of macroalgae were collected at six Thalassia testudinum Kö...

ATP sulfurylase (ATPS) catalyzes the first committed step in the sulfate assimilation pathway, the activation of sulfate prior to its reduction. ATPS has been studied in only a few model organisms and even in these cases to a much smaller extent than the sulfate reduction and cysteine synthesis enzymes. This is possibly because the latter were considered of greater regulatory importance for sul...

in the present study the freshwater algae of siahdarvishan river were sampled on a montly basis from december 2007 through november 2008. three sampling stations (gaght roudkhan , shahkezr dame and talab laleh ) were chosen in the river. some physical and chemical parameters (water temperature , total hardness , nitrate , nitrite, phosphate and ph) of water samples were measured. a total of 84 ...

The production and use areas of aquatic plants are investigated in the article. In recent times, development fishing all-round (as food, purchase environmentally oil, as fertilizer) is one main issues our day. Macroalgae basis cultivated sea products. Mainly, brown algae — laminaria, fucus, red Kappaphycus alvarezii Eucheuma widely used for both food alginate production. Spirulina algae, a repr...

During July, 1991, two young boys were brutally attacked by multiple teenaged assailants while fishing at a suburban Connecticut pond. After being accosted at knife point, the victims were bound with duct tape, beaten with a baseball bat and dragged into the pond to drown. One victim managed to free himself, rescue his colleague, and summon help from local residents. An exhaustive investigation...
