Phosphorus distribution in three crustacean zooplankton species
The distribution of phosphorus (P) was assessed in homogeneously 33P-labeled Daphnia magna, Daphnia galeata and Eudiaptomus gracilis. The specific P contents were 1.48, 1.41, and 0.50% of dry weight (DW), respectively. The results support the view of low intraspecific variability in P : DW ratios in crustacean zooplankton. The fraction of P allocated to nucleic acids, phospholipids, and other P...
متن کاملIntroduction to competition between continuous cultures of Phaeodactylum tricornutum and Dunaliella tertiolecta.
When the diatom, Phaeodactylum tricornutum, and the microalga, Dunaliella tertiolecta, are cultured together in a chemostat at dilution factors of approximately 0.5 day-1, the diatom develops the higher population density. At dilution factors above 1.2 day-1 the inability of the diatom to assimilate nutrient as fast as it flows into the chemostat results in the microalga generating the larger p...

متن کاملPotential heterogeneity in crustacean zooplankton assemblages in southern chilean saline lakes.
The Chilean saline lakes are distributed mainly in the Atacama desert in northern Chile and the southern Patagonian plains. The scarce studies are restricted mainly to northern Chilean saline lakes, and these revealed that the main component in these ecosystems are the halophylic copepod Boeckella poopoensis Marsh 1906, or the brine shrimp Artemia franciscana (Kellog, 1906), and both species do...
متن کاملExperimental whole-lake increase of dissolved organic carbon concentration produces unexpected increase in crustacean zooplankton density.
The observed pattern of lake browning, or increased terrestrial dissolved organic carbon (DOC) concentration, across the northern hemisphere has amplified the importance of understanding how consumer productivity varies with DOC concentration. Results from comparative studies suggest these increased DOC concentrations may reduce crustacean zooplankton productivity due to reductions in resource ...
