Restoration Handbook for Sagebrush Steppe Ecosystems, Part 2

CORVALLIS, Ore. — Ecosystem restoration is complex and requires an understanding of how the land, plants, and animals all interact with each other over large areas and over time. Today, the U.S. Geological Survey published part two of a three-part handbook addressing restoration of sagebrush ecosystems from the landscape to the site level.

Storage and Treatment of Liquid Waste from Landfills Doesn’t Remove All Contaminants, Including Pharmaceuticals

New research from the U.S. Geological Survey details that even after the storage and/or treatment of leachate – liquid waste that moves through or drains from a landfill − it can still contain a multitude of chemicals and reflects the diverse nature of residential, industrial, and commercial waste discarded into landfills in the United States.

Grass Carp Eggs Compromised by Settling on Streambeds

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.

Sage-grouse Priority Areas Function as an Interdependent Network

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.

What Happened to Early Mars’ Atmosphere? New Study Eliminates One Theory

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.
