The dissolution rates of diatom frustules, phytoliths, two diatomaceouslake sediments, a siliceous ooze from the Southern Ocean, a diatomite deposit, and a synthetic amorphous silica were measured in ...
Hydrogeomorphic features mediate the effects of land use/cover on reservoir productivity and food webs
Hydrogeomorphic land use cover on reservoir productivity food webs
font style='font-size:12px;'>
2014/4/18
Although effects of land use/cover on nutrient concentrations in aquaticsystems are well known, half or more of the variation in nutrient concentration remains unexplained by land use/cover alone. Hyd...
Assimilatory uptake rather than nitrification and denitrification determines nitrogen removal patterns in streams of varying land use
Assimilatory uptake nitrification denitrification deter nitrogen removal patterns in streams of varying land use
font style='font-size:12px;'>
2014/4/18
Agricultural and urban land use increase nitrogen (N) concentrations in streams, which can saturate biotic demand by plants, algae, and bacteria via assimilative uptake, and by nitrification and denit...

Nutrient variations in boreal and subarctic Swedish rivers: Landscape control of land– sea fluxes
boreal and subarctic Swedish land– sea fl uxes
font style='font-size:12px;'>
2014/5/19
We examined the hypothesis that the extent of vegetation cover governs the fluxes of nutrients from boreal and
subarctic river catchments to the sea. Fluxes of total organic carbon (TOC) and di...
