The effect of nitrogen deposition on the species richness of acid grasslands in Denmark: a comparison with a sudy performed on a European scale

The effect of nitrogen deposition on the species richness of acid grasslands in Denmark: a comparison with a study performed on a European scale.

The effect of atmospheric nitrogen deposition on the species richness of acid grasslands was investigated by combining data from a large Danish monitoring program with a large European data set, where a significant non-linear negative effect of nitrogen deposition had been demonstrated (Stevens et al., 2010). The nitrogen deposition range in Denmark is relatively small and when only considering...

The effect of nitrogen deposition on the species richness of acid grasslands in Denmark: a comparison with a European study

Impact of nitrogen deposition on the species richness of grasslands.

A transect of 68 acid grasslands across Great Britain, covering the lower range of ambient annual nitrogen deposition in the industrialized world (5 to 35 kg Nha-1 year-1), indicates that long-term, chronic nitrogen deposition has significantly reduced plant species richness. Species richness declines as a linear function of the rate of inorganic nitrogen deposition, with a reduction of one spe...

Nitrogen deposition threatens species richness of grasslands across Europe.

Evidence from an international survey in the Atlantic biogeographic region of Europe indicates that chronic nitrogen deposition is reducing plant species richness in acid grasslands. Across the deposition gradient in this region (2-44 kg N ha(-1) yr(-1)) species richness showed a curvilinear response, with greatest reductions in species richness when deposition increased from low levels. This h...

Soil Organic Carbon Stocks and Nitrogen Content Comparison in Different Slope Positions in Native Grasslands and Adjacent Cultivated Soils (Case Study: Kermanshah Mountain Rangelands, Iran)

Global warming has been largely driven by increasing atmospheric GHG (Green House Gasses), particularly carbon dioxide caused by fossil fuels burning. The current trend can not be stopped except by reducing fossil fuel consumption or storing organic carbon in soil or earthchr('39')s biological systems such as forests, rangelands and agricultural systems. This study was conducted to determine th...
