Nettles are favoured by nitrogen deposition.

Not exact matches

Glaser et al. show that dust deposition mediated by frequent tropical storms was an important source of nutrients for the Everglades until about 2800 years ago, when a climatic shift in the tropical Atlantic and Gulf of Mexico led to weather patterns that sharply decreased the level of dust inputs and led to a drier climate and a gradual loss of soil phosphorus, carbon, and nitrogen.

By analyzing data from 270 monitoring sites around the country, Zhang and his colleagues found that the amount of nitrogen deposition, as measured in precipitation, had increased by 60 % — or 8 kilograms per hectare per year — between 1980 and 201By analyzing data from 270 monitoring sites around the country, Zhang and his colleagues found that the amount of nitrogen deposition, as measured in precipitation, had increased by 60 % — or 8 kilograms per hectare per year — between 1980 and 201by 60 % — or 8 kilograms per hectare per year — between 1980 and 2010.

Their assessment revealed a consistent picture of increasing nitrate concentrations, the magnitude and pattern of which can only be explained by the observed increase in atmospheric nitrogen deposition.

Recent work by Brookshire et al. (2011) suggests that climate change - driven loss of soil nitrogen could outpace deposition by 3 to 1.

Possible mechanisms include (iv) fertilization of phytoplankton growth in the Southern Ocean by increased deposition of iron - containing dust from the atmosphere after being carried by winds from colder, drier continental areas, and a subsequent redistribution of limiting nutrients; (v) an increase in the whole ocean nutrient content (e.g., through input of material exposed on shelves or nitrogen fixation); and (vi) an increase in the ratio between carbon and other nutrients assimilated in organic material, resulting in a higher carbon export per unit of limiting nutrient exported.

A research group led by the South Korean Pohang University has measured the effects of atmospheric and fluvial nitrogen deposition [through nitrate] in the coastal seas around China, Korea and Japan.

Acid rain: Also called acid precipitation or acid deposition, acid rain is precipitation containing harmful amounts of nitric and sulfuric acids formed primarily by sulfur dioxide and nitrogen oxides released into the atmosphere when fossil fuels are burned.

Progress is however markedly slower for eutrophication, which is caused by excess nitrogen deposition resulting from emissions of nitrogen oxides (NOx) and ammonia (NH3).

Increased uptake in the past decade may be a consequence of a reduced rate of deforestation [217] and fertilization of the biosphere by atmospheric CO2 and nitrogen deposition [187].

This uncertainty is increasingly exacerbated by the effects of climate change, nitrogen deposition, and other forms of global change [31], [32].

Globally, biodiversity (represented by species richness and relative abundance) may decrease by 13 to 19 % due to a combination of land - use change, climate change and nitrogen deposition under four scenarios by 2050 relative to species present in 1970 (Duraiappah et al., 2005).
