A 24-year study of the effects of excess nitrogen and CO2 on grassland species composition found that over the long term, elevated CO2 in the presence of excess nitrogen increased the number of species lost. Increased dominance of some species was accompanied by loss of others.

  High CO2 dampens then amplifies N-induced diversity loss over 24 years - Nature
  
  from Butler, Ethan E.
  
  A long-term experiment in grassland communities finds that, over 24 years, enriching nitrogen caused increasingly greater diversity loss when carbon dioxide levels were increased, raising further concerns over the impacts of global environmental change on biodiversity.
