Balkan endemic nephropathy (BEN) patient from a BEN village in Romania. The photo was taken at a dialysis clinic in Romania where the patient traveled every 2 to 3 days to receive dialysis, the principal treatment option for people with BEN. This patient died from complications of BEN within a year after this photo was taken in 2000.

Closeup of Pliocene lignite coal from a Balkan endemic nephropathy (BEN) village in Serbia. Lignite is low rank, or relatively unaltered (soft, or "brown") coal, and is characterized by a brownish color and appearance that often resembles wood. This lignite releases copious amounts of dissolved organic substances into groundwater.

1958 black-and-white vertical aerial photo of South Cascade Glacier, northwestern Washington State. Top of photo is south.

This photo provides a look at the ongoing construction project to build the Audubon NWR Headquarters and Visitor Center in Coleharbor, ND. This project is being funded by the American Recovery and Reinvestment Act of 2009.

Nikola Pavlovic, a kidney specialist and a USGS collaborator on Balkan endemic nephropathy (BEN) studies from Serbia, is shown exposing a small Pliocene lignite bed near a BEN village in the Vratza area of Bulgaria. The Pliocene lignite seams vary greatly in size and extent. BEN villages are always close to these Pliocene lignite deposits.

Deschauensee's Anaconda (Eunectes deschauenseei). The snake pictured is a representative of a species discussed in the USGS snake risk assessment. This snake was photographed in its native range.

Two USGS topographers circa 1925, working with an alidade and plane table. The man on the left is believed to be Roland Whitman Burchard, who was the topographer for the USGS Grand Canyon Expedition of 1923.

Native Americans of the Miwok tribe in the northern Sierra Nevada, California carved these basins into the granite bedrock to produce salt for trade. They filled the basins with water from a salt spring and let the water evaporate, leaving a salt residue in the basin.

Brutus, a wolf being studied by USGS scientists, separates from his pack mates and appears to be heading back to the den. He stops at the head of the fiord and howls for 2-3 minutes. The scientists track his progress with binoculars past the river where they cannot go. They suspect that his mate has returned to the den, and that Brutus will join her there.

Brutus, a wolf being studied by USGS scientists, is chemically immobilized, measured, ear-tagged, and fitted with a radio collar near the Eureka airstrip on Ellesmere Island in the High Arctic, Nunavut, Canada.

Baldcypress forest along the banks of Rainey Lake, remnant of a dwindling habitat that is being studied by scientists at the NWRC.

The USGS had a antenna sight set up at Alder Creek to monitor fish movements through this dead forest killed by the eruption of Mt. Saint Helens

This picture was taken at our juvenile Chinook tagging shed (old town Sacramento) looking upstream at our release location for our study.

An American Alligator in Everglades National Park. The species was once listed as Endangered, but was removed in 1987 after a successful recovery.

American crocodiles are restricted in their range within the USA to southern Florida. Decisions on restoration of the Everglades must incorporate protection for this threatened species.

After tagging this fish, it was released back into the river.

Collecting samples (sediment, aquatic vegetation, benthic invertebrates, zooplankton, forage fish, and predatory fish) to evaluate δ 15N ratios in the food web within Liberty Bay to evaluate urbanization effects on the nearshore ecosystem. (Coastal Habitats in Puget Sound program).

Collecting sediment to look for evidence of forage fish (sand lance and/or surf smelt) spawning (eggs) in Liberty Bay - Puget Sound.
