Belowground communities usually support a much greater diversity of organisms than do
corresponding aboveground ones, and while the factors that regulate their diversity are far …

Atmospheric nitrogen (N) deposition is a recognized threat to plant diversity in temperate
and northern parts of Europe and North America. This paper assesses evidence from field …

Phosphorus and nitrogen are essential nutrient elements that are needed by plants in large
amounts. The arbuscular mycorrhizal symbiosis between plants and soil fungi improves …

Human activity in the last century has led to a significant increase in nitrogen (N) emissions
and atmospheric deposition. This N deposition has reached a level that has caused or is …

Abstract In the western United States vast acreages of land are exposed to low levels of
atmospheric nitrogen (N) deposition, with interspersed hotspots of elevated N deposition …

Arbuscular mycorrhizal (AM) fungi are integral components of grasslands because most
plants are associated with interconnected networks of AM hyphae. Mycorrhizae generally …

Arbuscular mycorrhiza is a mutually beneficial biological association between species in the
fungal phylum Glomeromycota and higher plants roots. The symbiosis is thought to have …
