3. Invasive Species
Ranked 2nd to habitat loss as major threat to biodiversity
Invasive species accelerate the rate of environmental change
Species adapt to environmental change on a geologic time scale- evolution (slow change)
Species can not adapt rapidly to these environmental changes created by invasive species

4. How do they get here? Global trade Removal of geographic barriers
Canals
Dams- creating new habitat in lakes
Transatlantic vessels
Ballast water

6. Ships- through ballast water
