Title: The Role of U.S. Coral Reefs in Coastal Protection - Rigorously valuing flood reduction benefits to inform coastal zone management decisions

• Sea otters are perhaps the best-known example of a "keystone predator".
• Sea otter behavior -- in particular diet specialization and limited mobility -- can mediate their effects on ecosystem dynamics.

A USGS video about manatees reveals that while the animals may act like the cows of the sea, they also have more than a bit of the magical siren or mermaid about them.  Go for a serene swim.

Out with the old, in with the new! A state-of-the-art aquatic science laboratory is being built on the shores of Lake Huron at the USGS Hammond Bay Biological Station (HBBS), one of seven field stations of the USGS Great Lakes Science Center, operated in partnership with the Great Lakes Fishery Commission.
