Modelling the inorganic nitrogen behaviour in a small Mediterranean forested catchment,Fuirosos (Catalonia)
inorganic nitrogen behaviour Mediterranean forested catchment Fuirosos
2010/2/20
The aim of this work was to couple a nitrogen (N) sub-model to already existent hydrological lumped (LU4-N) and semi-distributed (LU4-R-N and SD4-R-N) conceptual models, to improve our understanding o...

Modelling the ecosystem effects of nitrogen deposition：Model of Ecosystem Retention and Loss of Inorganic Nitrogen
nitrogen deposition Ecosystem Retention
2009/6/8
A catchment-scale mass-balance model of linked carbon and nitrogen cycling in ecosystems has been developed for simulating leaching losses of inorganic nitrogen. The model (MERLIN) considers linked bi...
Nutrient concentrations and fluxes for podzolic and gley soils at Plynlimon, mid-Wales: implications for modelling inorganic nitrogen and phosphorus in upland UK environments
Plynlimon Hafren Hore streams nitrate ammonium
2009/3/17
The effect of felling on stream nitrate, ammonium and soluble reactive phosphate (SRP) concentrations is examined for acidic and acid sensitive Sitka Spruce afforested catchments with podzolic and gle...
Dry and wet deposition of inorganic nitrogen compounds to a tropical pasture site（Rondônia, Brazil）
Dry and wet deposition inorganic nitrogen compounds tropical pasture site
2008/12/31
The input of nitrogen (N) to ecosystems has increased dramatically over the past decades. While total (wet + dry) N deposition has been extensively determined in temperate regions, only very few data ...
Effects of inorganic nitrogen on taxa-specific cyanobacterial growth and nifH expression in a subtropical estuary
Effects of inorganic nitrogen taxa-specific cyanobacterial growth nifH expression a subtropical estuary
2014/4/21
The potentially toxic, diazotrophic filamentous cyanobacterium Cylindrospermopsis raciborskii has recently become a common component in the summer phytoplankton in the St. Johns River (SJR) estuary, F...
Nitrification and inorganic nitrogen distribution in a large perturbed river/estuarine system:the Pearl River Estuary,China
Nitrification inorganic nitrogen distribution river/estuarine system
2010/1/18
We investigated the spatial distribution and seasonal variation of dissolved inorganic nitrogen in a large perturbed estuary, the Pearl River Estuary, based on three cruises conducted in winter (Janua...
In situ fluxes of dissolved inorganic nitrogen from the sponge community on Conch Reef, Key Largo, Florida
dissolved inorganic nitrogen the sponge community Conch Reef, Key Largo, Florida
2014/4/21
We measured ammonium and nitrate plus nitrite fluxes from 14 common spongespecies on a Florida Keys reef (Conch Reef) using a combination of incubation experiments and an in situ method that requires ...

Input and output of dissolved organic and inorganic nitrogen in subtropical forests of South China under high air pollution
organic and inorganic nitrogen subtropical forests South China high air pollution
2010/1/15
The nitrogen (N) emissions to the atmosphere and N deposition to forest ecosystems are increasing rapidly in Southeast Asia, but little is known about the fates and effects of elevated N deposition in...
Sponges as a source of dissolved inorganic nitrogen: Nitrification mediated by temperate sponges
Sponges source of dissolved inorganic nitrogen Nitrification mediated temperate sponges
2014/4/22
We evaluated rates of carbon and nitrogen ingestion from particulate organic matter and dissolved inorganic nitrogen excretion by six common sponge species from Mediterranean sublittoral rocky bottom ...
The effects of rainfall on the distribution of inorganic nitrogen and phosphorus in Discovery Bay, Jamaica
rainfall on the distribution inorganic nitrogen phosphorus in Discovery Bay Jamaica
2014/5/5
We sought to define the ambient concentrations of inorganic nitrogen and phosphorus in the coastal waters of Discovery Bay, Jamaica, and to investigate the effects of groundwater and rainfall on those...
Benthic algae control sediment–water column fluxes of organic and inorganic nitrogen compounds in a temperate lagoon
Benthic algae control sediment– water column fluxes organic and inorganic nitrogen compounds temperate lagoon
2014/5/22
Coastal lagoons are a common land-margin feature worldwide and function as an important filter for nutrients entering from the watershed. The shallow nature of lagoons leads to dominance by benthic au...
Inorganic nitrogen transformations in the bed of the Shingobee River, Minnesota, USA: Integrating hydrologic and biological processes using sediment perfusion cores
Inorganic nitrogen transformations the bed of the Shingobee River Minnesota USA Integrating hydrologic biological processes sediment perfusion cores
2014/5/20
Inorganic N transformations were examined in streambed sediments from the Shingobee River using sediment perfusion cores. The experimental design simulated groundwater-stream water mixing within sedim...
