Alteration of belowground carbon dynamics by nitrogen addition
"... have had substantial effects on ecosystem functioning. We document changes in the belowground C cycle near ponderosa pine trees experiencing experimental nitrogen (N) addition (50 and 150 kg N ha1 a1 as slow release urea since 1997) at two end-member sites along a pollution gradient in the San Berna ..."

RESEARCH ARTICLE Effects of Nitrogen Addition on Nitrogen Resorption in Temperate Shrublands in
"... Nutrient resorption from senescing leaves is a key mechanism of nutrient conservation for plants. The nutrient resorption efficiency is highly dependent on leaf nutrient status, species identity and soil nutrient availability. Nitrogen is a limiting nutrient in most ecosystems, it is widely reported ..."

is known on how plants in shrublands respond to nitrogen deposition across the world. In this study, we conducted a two-year nitrogen addi-tion manipulation experiment to explore the responses of nitrogen concentration in green and senescing leaves, and NRE of seven dominant species, namely, Vitex negundo
Effects of Nitrogen Addition and Fire on Plant Nitrogen Use in a Temperate Steppe
, 2014
"... Plant nitrogen (N) use strategies have great implications for primary production and ecosystem nutrient cycling. Given the increasing atmospheric N deposition received by most of the terrestrial ecosystems, understanding the responses of plant N use would facilitate the projection of plant-mediated ..."

concentrations and N use characters at both species and community levels in a temperate steppe of northern China. We found that N addition and fire independently affected soil N availability and plant N use traits. Nitrogen addition increased aboveground net primary productivity (ANPP), inorganic N, and N uptake
Effects of experimental nitrogen additions on plant diversity in an old-growth tropical forest.

SQ (2008) Global response patterns of terrestrial plant species to nitrogen addition
- New Phytologist
"... Summary • Better understanding of the responses of terrestrial plant species under global nitrogen (N) enrichment is critical for projection of changes in structure, functioning, and service of terrestrial ecosystems. • Here, a meta-analysis of data from 304 studies was carried out to reveal the ge ..."

Long-Term Nitrogen Additions and Nitrogen Saturation in Two Temperate Forests
"... This article reports responses of two different forest ecosystems to 9 years (1988–96) of chronic nitrogen (N) additions at the Harvard Forest, Petersham, Massachusetts. Ammonium nitrate (NH4NO3) was applied to a pine plantation and a native deciduous broad-leaved (hardwood) forest in six equal mont ..."

Soil Biochemical Responses to Nitrogen Addition in a Bamboo Forest
"... Many vital ecosystem processes take place in the soils and are greatly affected by the increasing active nitrogen (N) deposition observed globally. Nitrogen deposition generally affects ecosystem processes through the changes in soil biochemical properties such as soil nutrient availability, microbi ..."

Nitrogen Addition Regulates Soil Nematode Community Composition through Ammonium Suppression
"... Nitrogen (N) enrichment resulting from anthropogenic activities has greatly changed the composition and functioning of soil communities. Nematodes are one of the most abundant and diverse groups of soil organisms, and they occupy key trophic positions in the soil detritus food web. Nematodes have th ..."

Effects of experimental nitrogen additions on plant diversity in an old-growth tropical forest
"... Response of plant biodiversity to increased availability of nitrogen (N) has been investigated in temperate and boreal forests, which are typically N-limited, but little is known in tropical forests. We examined the effects of artificial N additions on plant diversity (species richness, density and ..."

Microbial activity and soil respiration under nitrogen addition in Alaskan boreal forest
"... Climate warming could increase rates of soil organic matter turnover and nutrient mineralization, particularly in northern high-latitude ecosystems. However, the effects of increasing nutrient availability on microbial processes in these ecosystems are poorly understood. To determine how soil microb ..."
Abstract

microbes respond to nutrient enrichment, we measured microbial biomass, extracellular enzyme activities, soil respiration, and the community composition of active fungi in nitrogen (N) fertilized soils of a boreal forest in central Alaska. We predicted that N addition would suppress fungal activity
