USGS Western Ecological Research Center scientist Lesley DeFalco pollinates sun cup flowers for the Desert Restoration Program. In the experiment pictured here, USGS scientists pollinated individual sun cup flowers using a small paintbrush to help increase seed stocks to use in experiments throughout the Mojave Desert.

USGS field scientist uses radio telemetry to search for skunks and raccoons tagged with lightweight radio collars. USGS is monitoring skunk and raccoon movements across California's inland marshes to understand how they are using different features of the landscape, like levee roads, to navigate to waterfowl nests.
