What are the short-term effects of a hurricane on an ecosystem?

Hurricanes generate strong winds that can completely defoliate forest canopies and cause dramatic structural changes in wooded ecosystems. Animals can either be killed by hurricanes or impacted indirectly through changes in habitat and food availability caused by high winds, storm surge, and intense rainfall.
