Elevated CO2 increases sensitivity to ultraviolet radiation in lacustrine phytoplankton assemblages
Elevated CO2 increases sensitivity ultraviolet radiation lacustrine phytoplankton assemblages
2014/4/17
This study tests the effects of elevated CO2 and ultraviolet radiation (UVR) on phytoplankton photosynthesis through in situ incubations in Lake Giles, Pennsylvania. In a first experiment, CO2 was sup...
Two High-Nutrient Low-Chlorophyll phytoplankton assemblages:the tropical central Pacific and the offshore Perú-Chile Current
High-Nutrient Low-Chlorophyll phytoplankton assemblages tropical central Pacific offshore Perú-Chile Current
2010/1/15
The phytoplankton (>15 μm) composition and abundance was investigated along a ~8000 km transect between the Marquesas Islands Archipelago and the Chilean coasts off Concepción. In the southern limit o...
The Influence of Certain Physical and Chemical Variables on the Seasonal Dynamics of Phytoplankton Assemblages of a Source Inlet and the Outlet of the Shallow Hypertrophic Lake Manyas, Turkey
Conductivity phytoplankton biovolume regression analysis turbidity water discharge
2010/3/18
The relationships between water discharge, temperature, pH, conductivity, turbidity, nitrate, ammonium, phosphate and the seasonal dynamics of phytoplankton assemblages of one of the inlets, which is ...
Inorganic carbon uptake and intracellular assimilation by subarctic Pacific phytoplankton assemblages
Inorganic carbon uptake intracellular assimilation subarctic Pacific phytoplankton assemblages
2014/5/5
We report the results of inorganic carbon (C) uptake experiments and activity measurements for carbonic anhydrase, ribulose 1,5-bisphosphate carboxylase/oxygenase (Rubisco), and phosphoenolpyruvate ca...
Bicarbonate transport and extracellular carbonic anhydrase activity in Bering Sea phytoplankton assemblages: Results from isotope disequilibrium experiments
Bicarbonate transport extracellular carbonic anhydrase activity Bering Sea phytoplankton assemblages isotope disequilibrium experiments
2014/5/5
We used a 14C isotope disequilibrium technique to provide quantitative estimates of both direct HCO3- transport and extracellular CA activity in Bering Sea phytoplankton assemblages. The method reveal...
Effects of dissolved carbon dioxide, zinc, and manganese on the cadmium to phosphorus ratio in natural phytoplankton assemblages
Effects of dissolved carbon dioxide, zinc, and manganese the cadmium to phosphorus ratio natural phytoplankton assemblages
2014/5/9
We report the results of a field study, in productive waters off California, of the factors that control the particulate cadmium (Cd) : phosphorus (P) composition of natural assemblages of marine phyt...
Effect of iron limitation on the cadmium to phosphorus ratio of natural phytoplankton assemblages from the Southern Ocean
iron limitation cadmium to phosphorus ratio natural phytoplankton assemblages Southern Ocean
2014/5/20
There is considerable interest in the biogeochemical cycling of cadmium (Cd) and phosphate (PO4) in surface waters, driven in part by the ongoing development of a paleonutrient proxy that utilizes Cd ...
Temporal mapping of phytoplankton assemblages in Lake Geneva: Annual and interannual changes in their patterns of succession
phytoplankton assemblages Lake Geneva: Annual and interannual changes
2014/5/26
The implementation of a conservation program since the early 1980s resulted in a reduction in phosphorus concentrations in Lake Geneva. However, in the 1990s, phytoplankton biomass increased again, al...
