Shown here is a colony of the threatened Elkhorn coral, Acropora palmata, that has succumbed to "bleaching," that is, lost all its algal symbionts (also called zooxanthellae) because of the summer 2023 ocean-heat wave. The coral is attached to a cement block as part of the U.S.

The Saline Lake Ecosystems IWAA Waterbird Movement Project began tagging American Avocets in March 2023 to track their movements across the landscape. Tracking data from these birds will help scientists better understand why these birds choose to use the terminal lake and wetland habitats they do in the Great Basin.

Three of the nine wild sea otter populations in the U.S. are federally listed as threatened. In California, USGS biologists have lead an annual population census to assess the local populations' recovery, working closely with state agencies and the Monterey Bay Aquarium.
