Feature Story - June 2013
The diversity of the tropics helps keep invasive species low.
Researchers conducted the first experiments testing the biotic resistance hypothesis. This hypothesis predicts that diverse communities, such as those in the tropics, are more resistant to invasion then communities that are less diverse. These experiments showed that introduced tunicates were more susceptible to predation in Panama then in Connecticut. Full Story
