Ecosystems Focal Areas and Examples of USGS Science
Today the Ecosystems Science Mission Area concentrates its research in eight areas that address modern ecological and social issues and the interests of public and private groups.
Species of Concern
Developing the knowledge base and tools to assess, conserve, and restore species of concern.
The USGS conducts research on species of concern to Federal land- and resource-management agencies. These include federally threatened, endangered, and candidate species; marine mammals; and inter-jurisdictional and migratory species. The USGS also works cooperatively with States to address species of concern to them. This often occurs through the Cooperative Research Units Program established by Congress, in part, for that purpose.
An example of a Federal species of concern is the polar bear, which is protected under the Marine Mammal Protection Act and listed as threatened under the Endangered Species Act. The USGS conducts long-term research on polar bears and their habitat. The goal of current research is to refine scientific models to project the status of polar bears. Much of this research occurs under the Changing Arctic Ecosystems Initiative, which informs resource management decisions for Arctic Alaska with scientific information about ecosystem response to a warming climate. http://alaska.usgs.gov/science/interdisciplinary_science/cae/index.php
Developing and adapting new technologies and tools to increase effectiveness, efficiency, safety, and accuracy in answering natural resource management questions.
Environmental DNA (eDNA) is shed from an organism into an environment. It can be detected from water, soil, air, or other non-biological sources within that environment using various molecular techniques. These techniques are widely used to determine if species are present that are rare, nocturnal, invasive, or otherwise difficult to detect, such as manatees, Asian carp, or Burmese pythons. Currently, the USGS is working with industry to develop a field-deployable eDNA test kit that would allow managers to conduct even quicker, more cost-effective surveillance to determine if key species are present. https://pubs.usgs.gov/fs/2012/3146/
Understanding biological and physical processes and the influences of changing conditions across large geographic areas and over long periods of time to support landscape-scale management decisions.
In sagebrush-steppe landscapes, fires and related invasion of cheatgrass threaten land use and healthy ecosystems. A U.S. Department of the Interior rangeland fire-management strategy describes actions to help prevent and suppress rangeland fire and restore fire-affected landscapes across the West. The USGS contributes to this strategy by providing science needed by managers to understand and reduce the threat of rangeland fire and to effectively restore landscapes to sustainable conditions. Combined with additional understanding of ecosystem resistance and resilience to change, the USGS informs adaptive management at the landscape-scale. http://www.usgs.gov/blogs/features/usgs_top_story/as-fires-ravage-the-west-usgs-responds/
Energy and Wildlife
Understanding environmental effects of energy development, and developing tools and strategies to assist in responsible development of energy resources while minimizing negative effects to wildlife.
Recent exponential growth in wind-energy capacity has raised concerns about negative effects on wildlife. USGS science helps discover reasons why some flying species, bats for instance, are susceptible to collision with turbines and to develop innovative tools to reduce injury and fatalities. Managers and industry operators now use the statistical tools developed by the USGS to estimate wildlife fatalities at wind facilities. New monitoring protocols and habitat models will provide the basis for understanding how species such as golden eagles could be affected by wind energy development, support permitting and siting of new facilities, and guide potential strategies for mitigation. http://www.usgs.gov/ecosystems/energy_wildlife/

Quantifying the production and value of services provided by species, communities, or ecosystems for the benefit of everyone.
Capture and storage of atmospheric carbon dioxide is an important ecosystem service helping to regulate the Earth’s climate. In collaboration with the National Park Service, the USGS is calculating the economic value of climate regulation from carbon sequestration in National Parks. They estimate that parks in the conterminous United States store 14.8 million metric tons of carbon dioxide each year, a service worth more than $580 million annually. This information reveals one of many nonmarket economic benefits produced by National Parks. http://www.usgs.gov/blogs/features/usgs_top_story/pricing-the-priceless-ecosystem-services-science-at-usgs/
Advancing the understanding of water-flow needs of species or aquatic communities and developing tools to evaluate tradeoffs in water-allocation decisions.
The Delaware River Basin, covering portions of New York, New Jersey, Pennsylvania, and Delaware, provides water to 15 million people and a variety of fish and wildlife. An integrative decision-support system developed by the USGS provides habitat data for key aquatic species, including both sport and migratory fish and federally endangered species. This decision-support system provides useful data for managers who must meet the diverse human and ecological water needs within the basin. https://pubs.usgs.gov/circ/1384/support/c1384.pdf
Emerging Diseases and Biosecurity

Describing the ecology of fish and wildlife diseases, and developing surveillance, control, and risk-assessment tools to support natural resource management and Federal biosecurity efforts.
White-nose syndrome, a fatal fungal infection of hibernating bats, has killed at least 6 million bats since 2006, threatening the survival of vulnerable populations of bats and even some species. The USGS is a national leader in white-nose syndrome research, discovering and understanding the disease in collaboration with partners, and supporting a national plan for managing the disease by developing treatment options. http://www.usgs.gov/blogs/features/usgs_top_story/trick-or-treat-the-frightening-threats-to-bats-2/
Developing early detection methods, control technologies, and risk assessments of economically or ecologically damaging invasive species.
USGS scientists work with Federal, State, local, and other agencies to deploy new technologies to protect a multi-billion dollar fishery by preventing the spread of Asian carp to the Great Lakes. USGS research is leading to molecular detection technologies to rapidly detect carp presence at low abundances in new areas, behavioral deterrents to prevent the spread of carp, and selective toxicants and targeted delivery technologies to reduce carp populations without harming native species. http://www.usgs.gov/ecosystems/invasive_species/
