Effects of water temperature, turbidity, and rainbow trout on humpback chub population dynamics
Humpback chub (Gila cypha Miller 1946), found only in the Colorado River Basin, was one of the first species to be given full protection under the Endangered Species Act of 1973. Habitat alterations, such as changes in flow and water temperature caused by dams, and the introduction of nonnative fish have contributed to population declines in...

Bat community response to silvicultural treatments in bottomland hardwood forests managed for wildlife in the Mississippi Alluvial Valley
Silvicultural treatments (e.g., selective timber harvests) that are prescribed to promote wildlife habitat are intended to alter the physical structure of forests to achieve conditions deemed beneficial for wildlife. Such treatments have been advocated for management of bottomland hardwood forests on public conservation lands in the Mississippi...

Remote Sensing and Dryland Management
Drylands (areas characterized by low precipitation, high evapotranspiration, and low soil moisture) occupy around 40-45% of the earth’s surface. Many drylands contain high biodiversity and provide essential ecosystem services (e.g., livestock forage, agricultural production, pollination) for nearly 1/3 of the world’s population who live in drylands. Given limited precipitation and other...

FLAGSTAFF, Ariz. – When you’re planning to explore someplace new, it’s always a good idea to bring a map so you can avoid dangerous terrain. This is true whether you’re heading out for a hike on Earth or you’re landing a rover on Mars.
A team of federal, academic, and NGO researchers conducted a national-scale assessment of mercury bioaccumulation in aquatic ecosystems using dragonfly larvae as biosentinels.
A new study describes how food web dynamics influence the movement of mercury throughout the Colorado River in the Grand Canyon. This new research from the U.S. Geological Survey and partners represents one of the first times that the movement and fate of mercury has been traced through an entire food web.
