Mother grizzly and cub at Gibbon River, Yellowstone National Park
Mother grizzly and cub at Gibbon River, Yellowstone National ParkA USGS grizzly bear researcher snapped this picture of a mother grizzly bear and her cub in Yellowstone National Park.

Close-up of biocrust - lichen
Biological soil crusts, or biocrusts, are lichens, mosses, and cyanobacteria that grow on the soil surface and are common in the spaces between native plants in arid and semi-arid systems. Biocrusts reduce soil erosion, contribute to nutrient and water cycling, and reduce evaporation and invasion by exotic plants.

Chesapeake Bay ospreys are healthy despite toxics in their fish diet
Chesapeake Bay ospreys are healthy despite toxics in their fish dietAn adult osprey brings a fish to its nestlings at Poplar Island, Maryland. USGS researchers placed game cameras in some osprey nests to identify the types of fish that Chesapeake Bay ospreys are eating, then tested those fish species for toxic chemicals.
