The increase of nitrogen (N) deposition and the diversity of its components lead to significant changes in the structure and function of temperate meadow steppe, which could affect plant nutrient uptake, nutrient resorption and litter decomposition, thus

Nitrogen deposition and ectomycorrhizas [PDF]
As a result of increasing anthropogenic nitrogen deposition, N availability in many forest ecosystems, which are normally N‐limited, has been enhanced. We discuss the impacts of this increased N availability on the ectomycorrhizal (ECM) symbiosis which is generally regarded as an adaptation to nutrient limited conditions.

Nitrogen deposition and carbon sequestration [PDF]
From their 15N tracer results1 and an estimated deposition rate to forests of 5.1×1012 g nitrogen per year2,3, Nadelhoffer et al.conclude that about 0.25×1015 g carbon per year is sequestered by northern temperate forests.

Physiological responses of two common mosses to simulated nitrogen deposition in Jiuzhaigou
In order to explore the effect of nitrogen deposition on physiological response of mosses in Jiuzhaigou, Sichuan Province, the local dominant mosses Actinothuidium hookeri and Hylocomium splendens were taken as the research objects, and NH4NO3 was used ...

Nitrogen deposition and climate: an integrated synthesis
Human activities have more than doubled reactive nitrogen (N) deposited in ecosystems, perturbing the N cycle and considerably impacting plant, animal, and microbial communities. However, biotic responses to N deposition can vary widely depending on factors including local climate and soils, limiting our ability to predict ecosystem responses. Here, we

Reduced nitrogen dominated nitrogen deposition in the United States, but its contribution to nitrogen deposition in China decreased [PDF]
Recently, Li et al. (1) report that reduced nitrogen (N) dominated both wet and dry deposition of inorganic N, following long-term N oxides (NO x ) emission controls introduced in 1990. They systematically compare wet deposition of inorganic N, measured by the US National Atmospheric Deposition Program (NADP) between 1990–1992 and 2010–2012, and ...

Functional indicators of response mechanisms to nitrogen deposition, ozone, and their interaction in two Mediterranean tree species [PDF]
The effects of nitrogen (N) deposition, tropospheric ozone (O3) and their interaction were investigated in two Mediterranean tree species, Fraxinus ornus L. (deciduous) and Quercus ilex L.

Impact of ship-borne nitrogen deposition on the Gulf of Finland ecosystem: an evaluation
The degree of inter-annual variability in spring and summer phytoplankton blooms and nitrogen fixation in response to the deposition of oxidized nitrogen originating from ship emissions (hereafter nitrogen deposition) was evaluated in the Gulf of Finland
