Sphagnum response to nitrogen deposition and nitrogen critical load: A meta-analysis

Global Ecology and Conservation, 2021
Sphagnum plants are sensitive to nitrogen deposition changes. However, previous literature is inconclusive on the response of Sphagnum to nitrogen deposition, little is known about the nitrogen critical load for Sphagnum growth, and the factors that ...

Nitrogen deposition and carbon sequestration [PDF]

Nature, 1999
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.

Weathering, atmospheric deposition and vegetation uptake: role for ecosystem sensitivity to acid deposition and critical load [PDF]

, 2004
Critical loads of acidity represent the maximum acceptable atmospheric deposition for an ecosystem type. Two hundred and forty-one ecosystem types have been defined in France using pedologic, geologic and vegetation data.

Effects of nitrogen deposition on the rhizosphere nitrogen-fixing bacterial community structure and assembly mechanisms in Camellia oleifera plantations

Frontiers in Microbiology
Increased nitrogen deposition is a key feature of global climate change, however, its effects on the structure and assembling mechanisms of the nitrogen-fixing bacteria present at the root surface remain to be elucidated.

Nitrogen Deposition and Responses of Forest Structure to Nitrogen Deposition in a Cool-Temperate Deciduous Forest [PDF]

Forests, 2019
Few studies have reported the estimation of nitrogen (N) deposition, including dissolved organic N (DON) fluxes, through water flows and the contribution of snowfall in Asia. In this study, the concentrations and fluxes of DON and dissolved inorganic N (DIN) in bulk precipitation (BP), the throughfall (TF) of trees and understory dwarf bamboo, and ...

Nitrogen deposition and its impact on forest ecosystems in the Czech Republic - change in soil chemistry and ground vegetation

iForest - Biogeosciences and Forestry, 2017
A repeated soil survey (1995 and 2006) on 66 ICP Forests pair plots in the Czech Republic revealed a significant relationship between modeled nitrogen deposition and nitrogen concentration in the soil.

Shifts in nitrogen deposition across an urban-rural-forest gradient

Earth Critical Zone
Atmospheric nitrogen deposition (N) significantly influences ecosystem structure and biodiversity conservation, and is largely driven by anthropogenic activities. This study investigated the effects of anthropogenic impact on nitrogen deposition across a
