Ecological consequences of increased nitrogen deposition in three northern Great Plains grasslands
Increased nitrogen deposition is an important driver of plant species composition change in terrestrial ecosystems globally. Plant composition change from increased nitrogen inputs can result in substantial species richness declines especially where atmospheric inputs already exceed critical loads. Shifts in community structure can occur through changes in basic ecosystem conditions (such as soil properties) or through alterations in competitive interactions potentially disrupting feedbacks that maintain an ecosystem at a given fertility level. Although there has been a substantial amount of ...
