Relationship between nutrients and phytoplankton biomass based on chlorophyll prediction model in Zribar Lake of Kurdestan, a case study
Zaribar Lake is a little shallow lake in Kurdistan province of Iran and it is faced to eutrophication.The study of phytoplankton biomass-nutrient relations is important in eutrophication management and there are many empirical models to predict phytoplankton biomass (chlorophyll a) based on nutrient (nitrogen and phosphorous) amounts in the lake. Evaluation of these empirical models and compar...
متن کاملImpact of dissolved organic carbon, phosphorus, and grazing on phytoplankton biomass and production in experimental lakes
Phytoplankton biomass and production in lakes tend to be increased by phosphorus input and decreased by grazing or high levels of colored, dissolved organic carbon (DOC). We estimated and compared the effects of these three factors by using data from three lakes that were manipulated during 1991-1995, and data from a reference lake. Multivariate probability distributions of chlorophyll or prima...
متن کاملRelative importance of iron and molybdenum in restricting phytoplankton biomass in high phosphorus saline lakes
Eleven prairie saline (conductivity 1.8-58.8 mS cm-‘) lakes were examined over the 1994 growing season to determine what salinity-related factor or factors were responsible for controlling phytoplankton standing crops. The study lakes were characterized by high total P (0.15-24.2 mg liter-‘), total N (3.75-12.35 mg liter-‘), total Fe (552,800 p,g liter-‘), dissolved organic C (40-195 mg liter-l...
متن کاملRelationships between Grain Yield and Accumulation of Biomass, Nitrogen and Phosphorus in Common Bean Cultivars(1)
Shoot biomass is considered a relevant component for crop yield, but relationships between biological productivity and grain yield in legume crops are usually difficult to establish. Two field experiments were carried out to investigate the relationships between grain yield, biomass production and N and P accumulation at reproductive stages of common bean (Phaseolus vulgaris) cultivars. Nine an...
متن کاملReference conditions and WFD compliant class boundaries for phytoplankton biomass and chlorophyll-a in Alpine lakes Authors
This paper has not been submitted elsewhere in identical or similar form, nor will it be during the first three months after its submission to Hydrobiologia Abstract The intercalibration (IC) exercise is a key element in the implementation of the Water Framework Directive (WFD) in Europe. Its focus lies on the harmonization of national classification methods to guarantee a common understanding ...
