The influence of nitrogen limitation on d15N and carbon : nitrogen ratios in sediments from sockeye salmon nursery lakes in British Columbia, Canada
nitrogen limitation on d15N and carbon nitrogen ratios in sediments sockeye salmon nursery lakes British Columbia Canada
2014/5/5
Carbon (C) and nitrogen (N) elemental and nitrogen isotopic ratios were determined for bulk organic matter in surface sediments of 11 sockeye salmon (Onchorynchus nerka) nursery lakes in British Colum...
Investigating the use of macrophyte stable C and N isotopic ratios as indicators of wetland eutrophication: Patterns in the P-affected Everglades
macrophyte stable C N isotopic ratios wetland eutrophication Patterns in the P-affected Everglades
2014/5/5
We investigated the use of stable C and N isotopic ratios as indicators of shifts in nutrient limitation of aquatic macrophytes in native Typha (Typha domingensis Pers.) and Cladium (Cladium jamaicens...
Coccolith strontium to calcium ratios in Emiliania huxleyi: The dependence on seawater strontium and calcium concentrations
Coccolith strontium Emiliania huxleyi seawater strontium
2014/4/23
In recent studies the Sr/Ca ratio of coccolithophore calcite was used as a proxy for past coccolithophore growth
and calcification rates. Since Sr and Ca concentrations in seawater have not rem...
Iron requirements for dinitrogen- and ammonium-supported growth in cultures of Trichodesmium (IMS 101): Comparison with nitrogen fixation rates and iron:carbon ratios of field populations
Iron requirements nitrogen- and ammonium-supported growth cultures of Trichodesmium nitrogen fixation rates and iron field populations
2014/5/21
We quantified the relationships among the specific growth rate, intracellular iron content, and steady state iron uptake rate for cultures of the marine diazotrophic cyanobacterium Trichodesmium (IMS ...
