Water tracing dye was injected into a stream in Leadville, Colorado, to identify locations of metal loading and to guide geophysical measurements.

Photographs from a colony of boulder brain coral (Colpophyllia natans) found losing tissue in Biscayne Bay, Miami, FL, US. (A). In situ photograph. An area of prior tissue loss is covered in algal overgrowth (O), new loss is evidenced by white, bare skeleton not yet overgrown by algae (S), and intact healthy-appearing tissue is greenish brown (H).

This site south of Rock Springs in Wyoming was not burned but cheatgrass has invaded the space between sagebrush shrubs.

This site was burned but not invaded by exotic annual grasses. Many perennial bunchgrasses were present before the fire and were able to recover quickly afterwards.

This landscape south of Rock Springs, Wyoming was burned and subsequently invaded by cheatgrass. Cheatgrass has a short growing season and leaves behind mats of dry, dead material that serves as wildfire fuel--contributing to a cycle of more frequent and larger wildfires and more plant invasions.

Orange streams are increasingly common in the Brooks Range of northern Alaska. The orange stream color reflects oxidized iron, but also often indicates elevated heavy metal concentrations. Our ongoing study aims to document these occurrences and the timing of their onset.

This landscape in Rabbit Valley in Colorado was burned and then invaded by the exotic annual grass cheatgrass. A formerly diverse plant community was replaced by a sea of highly flammable grass.
