Scale-dependent carbon : nitrogen : phosphorus seston stoichiometry in marine and freshwaters
The classical Redfield ratio of carbon106 : nitrogen16 : phosphorus1 is a cornerstone of biogeochemistry. With the use of .2,000 observations of the chemistry of particulate matter from small and large lakes, as well as nearand off-shore marine environments, we found that the best model to describe seston stoichiometry depended on the scale of analysis. We also found that there were better esti...

متن کاملEcological stoichiometry of TN : TP : SRSi in freshwaters: nutrient ratios and seasonal shifts in phytoplankton assemblages
Our concept of the ‘balance of TN : TP : SRSi-ratios’ attempts to determine whether the seasonal succession of phytoplankton communities is influenced by or responds to nutrient stoichiometry. Because the molar average of TN : TP : SRSi = 20 : 1 : 17 for 118 measurements (7 lakes, 3 inflows, all seasons) was close to the marine optimum stoichiometric ratio, we used the ratio TN : TP : SRSi = 16...
متن کاملEffects of the zebra mussel, an exotic freshwater species, on seston stoichiometry
We examined the effect of the zebra mussel, Dreissena polymorpha, an exotic species, on seston stoichiometry by conducting laboratory experiments in which we varied nutrient composition of seston and mussels over time. Zebra mussels altered the stoichiometry of seston through removal of particulate organic nutrients and changed the stoichiometry of the dissolved nutrient pool through nutrient e...
متن کاملsimulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water
abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...
