The researchers' biodiversity scenarios are based on current trends in factors that are known to affect biodiversity -- changes in atmospheric carbon dioxide and nitrogen deposition, climate changes, biotic exchanges (establishment of exotic species of plants or animals) and land-use changes -- and the known sensitivity of different ecosystems to these changes.
