P>1. Habitats are often connected by fluxes of energy and nutrients across their boundaries. For example, headwater streams are linked to surrounding riparian vegetation through invertebrate and leaf litter inputs, and there is evidence that consumers in downstream habitats are subsidised by resources flowing from headwater systems. However, the strength of these linkages and the manner in which potential headwater subsidies vary along climatic and disturbance gradients are unknown. 2. We quantified the downstream transport of invertebrates, organic matter and inorganic sediment from 60 fishless headwater streams in the Wenatchee River Basin located on the eastern slope of the Cascade Range in Washington, U.S.A....

Abstract: Topock Marsh is a large wetland adjacent to the Colorado River and the main feature of Havasu National Wildlife Refuge (Havasu NWR) in southern Arizona. In 2010, the U.S. Fish and Wildlife Service (FWS) and Bureau of Reclamation began a project to improve water management capabilities at Topock Marsh and protect habitats and species. Initial construction required a drawdown, which caused below-average inflows and water depths in 2010–11. U.S. Geological Survey Fort Collins Science Center (FORT) scientists collected an assemblage of biotic, abiotic, and hydrologic data from Topock Marsh during the drawdown and immediately after, thus obtaining valuable information needed by FWS. Building upon that work,...

Many management agencies seek to evaluate temporal changes in aquatic assemblages at monitoring sites, but few have sites with ecological time series that are long enough for this purpose. Trends in aquatic-invertebrate and fish assemblage composition were assessed at 27 long-term monitoring sites in the north-central and northeastern United States. Temporal changes were identified using serial trend analysis. Sites with significant serial trends were further evaluated by relating explanatory environmental variables (e.g., streamflow, habitat, and water chemistry) to changes in assemblage composition. Significant trends were found at 19 of 27 study sites; however, differences in the sensitivity of the aquatic fauna...

How well are we protecting common plants and animals? Gap Analysis is the science of answering this question. Developing the data and tools to support that science is the mission of the USGS Gap Analysis Program (GAP). GAP works to ensure that common species – those that are not officially endangered – remain common by identifying those species and plant communities that are not adequately represented in existing conservation lands. Learn more about Gap Analysis >> We work with a wide range of government, academic, non-profit and private partners, providing them with essential data and analyses that they can use to protect the habitats on which the survival of common species depends.

Solar development has the potential to have widespread impacts on the California desert. Thus, it is important to have as much information as possible regarding the impacts of facilities and related infrastructure on the natural ecosystem and surrounding desert communities, how current policies are influencing development, and how the federal process is working on evaluating solar development applications. This research is detailed in this website. "Renewable Energy in the California Desert: Mechanisms for Evaluating Solar Development on Public Lands" is the result of sixteen months of research conducted by ten graduate students from the University of Michigan School of Natural Resources and Environmen t through...

Chihuahuan Desert landscapes exemplify the ecological conditions, vulnerability, and management challenges in arid and semi-arid regions around the world. The goal of the Jornada Basin Long Term Ecological Research program (JRN LTER) established in 1982 is to understand and quantify the key factors and processes controlling ecosystem dynamics and patterns in Chihuahuan Desert landscapes. In collaboration with the Jornada Experimental Range (USDA ARS), studies initiated in 1915 have been incorporated into the JRN LTER program. Previous research focused on desertification, a state change from perennial grasslands to woody plant dominance that occurs globally. Based on findings from growing long-term databases, the...

REAs synthesize the best available information about resource conditions and trends within an ecoregion. They highlight and map areas of high ecological value, including important wildlife habitats and corridors, and gauge their potential risks from climate change, wildfires, invasive species, energy development, and urban growth. REAs also map areas that have high energy development potential, and relatively low ecological value, which could be best-suited for siting future energy development. In addition, REAs establish landscape-scale baseline ecological data to gauge the effect and effectiveness of future management actions. The Sonoran Desert REA was initiated in July 2010. It has been completed and peer reviewed...

Description of Work Elevated concentrations of major ions are associated with a variety of discharges to aquatic ecosystems, including urban wastewater, mountain top removal and valley fill operations, and coal bed methane production. There is considerable uncertainty regarding the toxicity of major ions to aquatic organisms, particularly given the variability of constituents that comprise these effluents. Because the relative toxicity of major ions is highly variable, predicting effects based on conductivity, total dissolved solids (TDS) or other composite measures may be simplistic. Furthermore, most of the available information on sensitivity of aquatic organisms to major ions has been derived from short-term...
