CORVALLIS, Ore. — Heightened interest in advancing sage-grouse conservation has increased the importance of sagebrush-steppe restoration to recover or create wildlife habitat conditions that meet the species’ needs.

Grass carp egg survival is compromised when they settle on streambeds and are potentially covered by sediments, according to a new study by the U.S. Geological Survey. It has been long assumed that the eggs of Asian carps, including grass carp, must be carried in the water current in order to hatch successfully, but no previous scientific studies have proven that theory.

Silver carp, a species of invasive Asian carp, demonstrated a strong aversion to certain noises during a recent study on the potential use of sound for silver carp control.

OAKHURST, Calif. -- Overall fire threats to greater sage-grouse habitat are much higher in the western part of the species’ range than in the eastern part, according to a U.S. Geological Survey fire threats assessment study published today.

BOISE, Idaho — The network of greater sage-grouse priority areas is a highly centralized system of conservation reserves. The largest priority areas likely can support sage-grouse populations within their boundaries, but smaller priority areas will need to rely on their neighbors in the surrounding network to sustain local populations, according to new research by the U.S. Geological Survey.

A new analysis of the largest known deposit of carbonate minerals on Mars helps limit the range of possible answers about how and why Mars changed from a world with watery environments billions of years ago to the arid Red Planet of today.

From the 1880s to the 1950s, the U.S. Geological Survey (USGS) engraved information from its surveys on metal plates (usually copper) as part of a lithographic printing process to reproduce topographic and geologic maps, geologic cross sections, and other illustrations. The engraved plates show point and line symbols and text for topography, hydrography, geology, and cultural features.

Trends in pesticide concentrations in 38 major rivers in the U.S. during 1992-2010 reflect large-scale trends in pesticide use and regulatory changes, according to a new study by the U.S. Geological Survey.

In a paper released today in Science, a new model presents a common mathematical structure that underlies the full range of feeding strategies of plants and animals: from familiar parasites, predators, and scavengers to more obscure parasitic castrators and decomposers. Now ecologists can view all food-web interactions through the same lens using a common language to understand the natural world.

ANCHORAGE, Alaska — In the 20th century, Baranof Island in Southeastern Alaska has drawn attention for its gold, chrome and nickel deposits, timber industry, potential activity of the dormant Mount Edgecumbe volcano, and for numerous commercially developed hot springs.

A new paper led by U.S. Geological Survey Ecologists Erik Beever (Northern Rocky Mountain Science Center) and Michelle Staudinger (Northeast Climate Science Center) addresses the importance of including adaptive capacity of species as a fundamental component when assessing vulnerability to rapid climate change.
