- Global Warming & Biodiversity Conservation – The billions of tons of carbon dioxide we’re dumping into the atmosphere every year may be undoing millions of years of evolution in a geological blink of time. The last time CO2 levels were as high as they are today was about twenty-three million years ago.
- Conservation Biogeography – Environmental change is driving change in the geographic distribution of species. What management actions can we take to save disappearing wildlife?
