An experimental plot that was drill seeded with native grasses after the Martin Fire in northern Nevada. Drill seeding is a method in which a drill buries seeds into the soil at a targeted depth that is ideal for that plant species. A tractor typically pulls the drill along to bury the seeds in rows.

Smallmouth Bass are good indicators of methylmercury exposure to humans and wildlife because they are a common, popular sport fish and eat a variety of food during their lifetime. Juvenile Smallmouth Bass – smaller than 150mm in length - eat zooplankton, or microscopic animals.

Cheatgrass growing in a high-density plot covered in black gravel. Black gravel warms the soil surface. The colors on the toothpicks indicate the genotype of cheatgrass planted. Researchers selected a variety of genotypes—plants of the same species that are genetically distinct—that are found locally.

A photograph and x-ray taken during an examination of a bald eagle found dead near a power line near Jordan Valley, Oregon. Because of the extensive singeing of the feathers on the wings and body, the bird was initially assumed to have died from electrocution.
