Wild celery in Pool 13 of the Upper Mississippi River
Wild celery in Pool 13 of the Upper Mississippi RiverWild celery (Vallisneria americana) within lower Pool 13 of the Upper Mississippi River.
Prevalence of submersed aquatic vegetation, especially wild celery, increased from 1998 to 2008 but has since declined in Pool 13.

Columbia torrent salamander (Rhyacotriton kezeri)
Torrent salamanders are Northwest-U.S. endemic, headwater-stream-associated amphibian species that have a dearth of basic ecological information, but are thought to be highly vulnerable to habitat changes.

Adaptive Management and Monitoring of Pyramid Lake, Nevada UT
Adaptive Management and Monitoring of Pyramid Lake, Nevada UTPyramid Lake, Nevada, is one of the last remaining strongholds for lacustrine Lahontan cutthroat trout; almost all other large lake populations have undergone population declines or extirpation as a result of habitat degradation, overharvest, and water diversions, all compounded by the stocking of nonnative species.
