Differential uptake of dissolved and particulate organic carbon by the marine mussel Perna viridis
Differential uptake of dissolved particulate organic carbon marine mussel Perna viridis
2014/5/19
We used radiotracers in laboratory experiments to determine the organic carbon uptake by the marine mussel Perna viridis from different diets (phytoplankton and detritus) and from the dissolved phase ...
The stoichiometry of dissolved organic carbon, nitrogen, and phosphorus release by a planktonic grazer, Daphnia
dissolved organic carbon nitrogen phosphorus release
2014/5/19
We examined the relationship between Daphnia release rates and ratios of dissolved organic carbon (DOC),
nitrogen (N), and phosphorus (P) and the elemental composition of algal food. We constructed a...
Significance and mechanisms of photosynthetic production of dissolved organic carbon in a coastal eutrophic ecosystem
Signifi cance mechanisms dissolved organic

We have determined the seasonal (July 2001–July 2002) and vertical variability in the photosynthetic production
of dissolved organic carbon (DOCp) and particulate organic carbon (POCp) in a coastal u...
Seasonal bioavailability of dissolved organic carbon and nitrogen from pristine and polluted freshwater wetlands
Seasonal bioavailability pristine
2014/5/19
We examined the chemical composition and bioavailability of dissolved organic carbon (DOC) and nitrogen
(DON) from two pristine and two polluted cedar bog wetlands across three seasons. Pristine and ...
Interannual variation of the isotopic composition of sedimenting organic carbon and nitrogen in Lake Lugano: A long-term sediment trap study
Interannual variation isotopic composition sedimenting organic carbon and nitrogen Lake Lugano long-term sediment trap study
2014/5/14
We examined the evolution of δ13C and δ15N of sedimenting particulate organic matter (SPOM) in response to changes in primary productivity, nutrient loading, and plankton dynamics in Lake Lugano betwe...

The photo- and bioreactive components of dissolved organic matter (DOM) from three different environments were
determined during long-term decomposition experiments. Terrigenous DOM was collected fro...
Cycling of colloidal organic carbon and nitrogen during an estuarine phytoplankton bloom
colloidal organic carbon and nitrogen estuarine phytoplankton bloom
2014/5/22
To establish the influence of phytoplankton blooms on the cycling of dissolved and particulate species of organic carbon and nitrogen, we conducted a field study during a series of blooms in a coastal...
Regional comparisons of watershed determinants of dissolved organic carbon in temperate lakes from the Upper Great Lakes region and selected regions globally
Regional comparisons watershed determinants dissolved organic carbon in temperate lakes Upper Great Lakes region selected regions globally

Ultraviolet radiation blocks the organic carbon exchange between the dissolved phase and the gel phase in the ocean
Ultraviolet radiation blocks the dissolved phase
2014/5/21
Dissolved organic carbon (DOC) is one of the major reservoirs of active organic carbon on Earth. Although the
bulk of the marine DOC pool is largely composed of small refractory polymeric material, n...
