Document Summary
Global and regional climate change air pollution: acid rain/n deposition. What drives change? habitat loss and fragmentation climate change pollution succession invading exotic species. Deer results: shifts in distribution and abundance population and species extinctions homogenization of floras and faunas. Causes of extinction in the u. s. five primary anthropogenic causes: habitat destruction, non-native species, pollution, over-exploitation, disease. Drivers of change: studies of long-term change in wisconsin plant communities.

Challenges to studying long-term change few 14259$ for monitoring few standard metrics long-term studies are rare missing baseline . Most science is either short-term or geologic in time scale results in the invisible present changes occur, but we cannot see them an absence of data is often used to infer an absence of impacts. What drives ecological change? succession system changes itself - increasing shade fire suppression.
