USGS scientist Art Bookstrom looks at greenish copper stain and pale pink cobalt bloom on limonite-stained meta-siltite and meta-argillite at the No Name prospect, near Iron Creek, in the southeastern part of the Idaho cobalt belt, in east-central Idaho.

A test-well for collecting gas hydrates in Mallik, Canada. Gas hydrates are naturally-occurring “ice-like” combinations of natural gas and water that have the potential to provide an immense resource of natural gas from the world’s oceans and polar regions.

Blackside dace are a type of minnow with a red underbelly and a black stripe down their sides. They are found only in parts of Tennessee, Kentucky, and western Virginia. The image shows a school of Blackside dace.

This photo was taken at Station 4 in 2009 before the Great Works Dam was removed. This location was just upstream of the dam and water levels are significantly lower now that the dam is removed.

IGBST researchers begin gathering biological data from the bear.  The kerchief over the bear's eyes protects it from dust and debris and reduces visual stimulation. The small tubing in its nose, known as a nasal cannula, delivers oxygen to the animal while it is tranquilized.

Drought and climate change are causing extensive forest dieback in the U.S. West as well as worldwide. These photos show dead ponderosa pines in the Jemez Mountains of New Mexico killed by a combination of drought stress and attacks by bark beetles on weakened trees.

Many species of Hawaiian honeycreepers have persisted into the 20th century because high elevation rain forests on the islands of Kaua’i, Maui, and Hawai’i are cool enough to limit transmission of introduced avian malaria (Plasmodium relictum).

These live Asian swamp eels were imported from southeast Asia and sold in an urban food market in the U.S. Raw or undercooked Asian swamp eels could transmit a parasitic infection called gnathostomiasis to consumers, and wild eels could become widespread in some U.S. waters.

A photomicrograph depicting the calcium carbonate tests of ten species of marine foraminiferans. Upon death, their tests can form calcareous marine sediments known as foraminiferan ooze.

Back-lit photographs of wings of White-nose Syndrome (WNS)-positive little brown bats, one with subtle circular and irregular pale areas (arrows) indicating areas of fungal infection (A) and another bat (B) with areas of relatively normal tone and elasticity (black arrow), compared to a WNS affected area that looks like crumpled tissue paper with loss of elasticity,
