Mats of the nonnative macroalga, Gracilaria vermiculophylla, alter net denitrification rates and nutrient fluxes on intertidal mudflats
nonnative macroalga Gracilaria vermiculophylla
2014/4/2
We hypothesized that mats of a nonnative macroalga, Gracilaria vermiculophylla, which is often found
incorporated several centimeters into intertidal mudflat sediments, would increase net denitrifica...
Production of nitrogen gas via anammox and denitrification in intact sediment cores along a continental shelf to slope transect in the North Atlantic
Production of nitrogen gas anammox denitrification intact sediment cores a continental shelf slope transect the North Atlantic
2014/4/17
We measured the production of N2 gas from anammox and denitrification simultaneously in intact sediment cores at six sites along a transect of the continental shelf (50 m) and deeper slope (2000 m) in...
The effect of increased nitrate loading on nitrate reduction via denitrification and DNRA in salt marsh sediments

The effects of increased nitrogen loading on denitrification and dissimilatory nitrate reduction to ammonium
(DNRA) in marsh sediments were studied in permanently submerged subtidal creek sediments a...
Denitrification in shallow, sublittoral Gulf of Mexico permeable sediments
Denitrification in shallow sublittoral Gulf Mexico permeable sediments
2014/4/16
We examined nitrogen cycling over a 1-yr period in shallow, sandy sediments at two contrasting sites near a barrier island in the northeastern Gulf of Mexico, and we provide here the direct determinat...
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
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...
Benthic nitrogen fluxes along a depth gradient in a microtidal fjord: The role of denitrification and microphytobenthos
Benthic nitrogen fluxes depth gradient microtidal fjord denitrification microphytobenthos
2014/5/19
In littoral sediments, microphytobenthic (MPB) nitrogen assimilation often exceeds nitrogen removal by denitrification, partly because MPB activity suppresses denitrification. Little is known about th...
