As diving foragers, sea ducks are vulnerable to underwater anthropogenic activities, including naval sonar activity and gillnet fisheries. Bycatch in gillnets is a principle driver of mortality for sea ducks, killing hundreds of thousands of seabirds annually. To reduce gillnet bycatch, underwater hearing tests were conducted on affected sea duck species to assist with possible development of...

In 1994, USGS scientists recognized that despite increasing concern for many species of bats known or believed to be declining, the data necessary to determine population status and trends were fragmented among agencies and organizations. Thus began the USGS Bat Population Data Project, which has become a multi-phase, comprehensive effort to compile existing population information for bats in the...

Bats are the only flying mammals that are active mostly at night and occur on all continents except Antarctica. Bats are ecologically diverse, with a range of species that specialize in feeding on fruit, nectar, blood, fish, small mammals, and insects. However, of the more than 1,100 known species of bats on Earth, the majority specialize in feeding on insects. In the United States for example, of...

Wind energy is one of the fastest-growing industries in the world and represents an important step toward reducing dependence on nonrenewable sources of power. However, widespread deployment of industrial wind turbines is having unprecedented adverse effects on certain species of bats that roost in trees and migrate. Bats are beneficial consumers of agricultural insect pests and migratory species...

As the Nation strives to lessen its dependence on foreign oil, domestic energy production has increased dramatically. This is especially true for renewable energy sources such as wind: from 2007 to 2009, for example, wind energy development increased 341 percent in Wyoming, and it continues on that trajectory today. However, the effects of renewable energy development on wildlife and habitats...

USGS and university researchers analyzed changes in male sage-grouse lek counts in Wyoming from 1984 through 2008, measuring disturbance owing to oil and gas development.
