Quantitative estimates labile semi-labile dissolved organic carbon western Arctic Ocean A molecular approach
2014/4/21
A novel molecular approach based on carbon-normalized yields of combined amino acids was developed to quantify concentrations of labile (L), semi-labile (S), and refractory (R) dissolved organic carbo...
Coral cavities are sinks of dissolved organic carbon (DOC)
Coral cavities dissolved organic carbon
2014/4/21
We studied the removal of dissolved organic carbon (DOC) by coral cavities of 50-250 dm3 at a depth range of 5-17 m along the coral reefs of Curaçao, Netherlands Antilles, and the Berau area, Eas...
Respiration of allochthonous organic carbon in unproductive forest lakes determined by the Keeling plot method
Respiration of allochthonous organic carbon unproductive forest lakes determined the Keeling plot method
2014/4/23
We carried out short-term (2 d) experiments in nine unproductive lakes in northern Sweden in order to investigate organic carbon sources supporting lake water respiration. Surface water was incubated ...
Large-scale variability in surface bacterial carbon demand and growth efficiency in the subtropical northeast Atlantic Ocean
Large-scale variability in surface bacterial carbon demand and growth efficiency in the subtropical northeast Atlantic Ocean
2014/4/23
We present surface estimates of bacterial respiration, bacterial heterotrophic production (BHP), and bacterial growth efficiency (BGE), and their relationship with nutrient availability, along a troph...

Kinetics of phosphorus in Daphnia at different food concentrations and carbon:phosphorus ratios
Kinetics of phosphorus in Daphnia different food concentrations carbon:phosphorus ratios
2014/4/22
We examined the assimilation efficiency, excretion, and efflux of phosphorus (P) in adults and juveniles of Daphnia magna under different food levels (2-40 μg P L-1) and dietary carbon : phosphorus (C...
Pathways of anaerobic carbon cycling across an ombrotrophic-minerotrophic peatland gradient
Pathways of anaerobic carbon cycling an ombrotrophic-minerotrophic peatland gradient
2014/4/22
Peatland soils represent globally significant stores of carbon, and understanding carbon cycling pathways in these ecosystems has important implications for global climate change. We measured aceticla...
