Western Skink
The Western skink (Plestiodon skiltonianus) is a relatively common and widespread lizard in Southern California. It is more secretive and prefers more grassy habitat than the Western fence lizard or the side-blotched lizard, yet USGS and National Park Service biologists are finding signs of genetic isolation in all these species.

Extremophilic Microbial Mats
Water run off from the Excelsior geyser hot spring. Various extremophilic microbial mats (Domains Archaea and Eubacteria) living in the hot springs, acidic habitats, and geyser basins. Notice the bands of color as microbial populations separate according to their tolerance for differing temperature and/or pH gradients.

Remnants of a spruce forest
Remnants of a spruce forest complex following a severe wildfire in the Yukon Flats National Wildlife Refuge, Alaska. Wildfires are the dominant landscape-scale disturbance operating at annual time scales in Alaska, and fires play a major role in the rate and extent of vegetation growth and productivity of a site.

A meltwater stonefly larva (Lednia tumana)
A meltwater stonefly larva (Lednia tumana) sits on a cobbled snow fed stream in Glacier National Park. The species is threatened by climate warming induced glacier and snow loss and has been petitioned for protection under the U.S. Endangered Species Act due to climate-change-induced habitat loss.

Low-density Waterfowl in California Wetlands
Waterfowl in California can spread the avian influenza virus (AIv) during summertime when wetland temperatures are warm and waterfowl densities are low.
