Population regulation of the spiny water flea (Bythotrephes longimanus) in a reservoir: Implications for invasion
Population regulation the spiny water flea a reservoir: Implications for invasion
2014/4/2
We conducted a 3-yr study of the population dynamics of the invasive cladoceranBythotrephes longimanusin Island Lake Reservoir (Minnesota) and compared our results to other human-constructed reservoir...
Alkaline phosphatase activity and regulation in the North Pacific Subtropical Gyre
Alkaline phosphatase activity regulation the North Pacific Subtropical Gyre
2014/4/17
Alkaline phosphatase (AP) activity (APA) was measured at several stations in the North Pacific Subtropical Gyre in July 2008, and in a series of nutrient addition experiments: nitrate plus ammonium (+...
Regulation of spatial and temporal variability of carbon flux in six hard-water lakes of the northern Great Plains
Regulation of spatial temporal variability carbon flux six hard-water lakes northern Great Plains
2014/4/17
Six hard-water lakes were sampled May-August for 14 yr in a 52,000 km2 catchment to identify the mechanisms that regulate the spatial and temporal variability of net atmospheric exchange of CO2 of lak...
Rates and regulation of anaerobic ammonium oxidation and denitrification in the Black Sea
Rates and regulation anaerobic ammonium oxidation denitrification Black Sea
2014/4/18
We performed incubation experiments with 15N-labeled nitrogen compounds to investigate the vertical distribution of pathways of N2 production through the suboxic zone of the central Black Sea and the ...
Phylogenetic diversity in cadmium : phosphorus ratio regulation by marine phytoplankton
Phylogenetic diversity cadmium phosphorus ratio regulation marine phytoplankton
2014/4/22
We examined the effect of irradiance and growth rate on cadmium : phosphorus ratio in five species of phytoplankton representing four different phylogenetic groups to determine the relative importance...
Temporal dynamics and regulation of lake metabolism
Temporal dynamics and regulation lake metabolism
2014/4/22
We studied temporal dynamics and regulation of oxygen metabolism in the upper mixed layer of a nutrientrich shallow Danish lake by continuous measurements of oxygen, irradiance, wind, and temperature ...
Regulation of nutrient uptake in eutrophic lowland streams
Regulation of nutrient uptake eutrophic lowland streams
2014/5/4
We studied nutrient uptake in relation to water chemistry, stream hydrodynamics, and ecosystem metabolism in two eutrophic lowland streams located near Berlin, Germany. Ambient nutrient uptake rates r...
Presence and regulation of alkaline phosphatase activity in eukaryotic phytoplankton from the coastal ocean: Implications for dissolved organic phosphorus remineralization
Presence and regulation alkaline phosphatase activity eukaryotic phytoplankton the coastal ocean Implications for dissolved organic phosphorus remineralization
2014/5/4
The biologically important constituents of the dissolved organic phosphorus (DOP) pool, their bioavailability, and their cycling in coastal systems are still poorly understood. Here we use the enzyme ...
Interactive regulation of dissolved copper toxicity by an estuarine microbial community
Interactive regulation copper toxicity estuarine microbial community
2014/5/19
Cultured marine microorganisms under copper stress produce extracellular compounds having a high affinity for copper (copper-complexing ligands). These ligands are similar in binding strength to those...
Regulation of bacterial biomass and community structure by metazoan and protozoan predation
Regulation of bacterial biomass community structure by metazoan protozoan predation
2014/5/30
We performed food web manipulation experiments in three eutrophic Daphnia-dominated ponds, to compare the predation impact on planktonic bacteria exerted by metazoan and protozoan bacterial consumers....
