With electric generation responsible for 41 percent of U.S anthropogenic carbon dioxide (CO2) emissions from energy use, development of clean energy sources is essential if the United States is to reduce release of greenhouse gases and slow global warming. Many proponents of sustainable energy anticipate that electric generation from renewable sources would thrive in a deregulated market, driven by consumer demand for "green" energy and the end of incentives to build large central power plants under the cost-plus profits guaranteed by state utility commissions. This paper examines the flaws in this expectation. After reviewing the highly cyclical nature of U.S. energy policy making in recent decades, the study links...

The Appalachian region is rich in biodiversity that is highly threatened by energy production, development, and a host of other factors. Large-scale impacts such as climate change will play out within this context, affecting habitats and species in different ways. Understanding the vulnerability of various species and habitats within the Appalachian LCC to such changes is of critical importance. Identifying the steps needed to acquire vulnerability information and then using this information to inform adaptation and mitigation strategies is a major research priority of the LCC.The Appalachian LCC provided a grant to NatureServe to conduct critical vulnerability assessments. Researchers first convened a panel of...

Recent reintroduction of the black-footed ferret (Mustela nigripes) in west-central South Dakota has focused new attention on black-tailed prairie dogs (Cynomys ludovicianus), because prairie dog colonies provide essential habitat for ferrets. Currently, management agencies are assessing prairie dog populations by counting active burrows, a technique that is attracting criticism. We correlated active and total burrow counts with prairie dog mark-recapture population estimates from 12 colonies located in Badlands National Park and adjacent Buffalo Gap National Grassland. We also correlated visual counts of prairie dogs and counts of mounds from aerial photographs with mark-recapture estimates to assess an alternative...

To date, hydrological and ecological models have been developed independently from each other, making their application particularly challenging for interdisciplinary studies. The objective of this project was to synthesize and evaluate prevailing hydrological and ecological models in the South-Central U.S., particularly the southern Great Plains region. This analysis aimed to identify the data requirements and suitability of each model to simulate stream flow while addressing associated changes in the ecology of stream systems, and to portray climate variability and uncertainty. The results and deliverables of this project are expected to include a comprehensive, updated, and systematic report on recent developments...

This thematic map illustrates the projected annual compound population growth rate in the United States from 2010 to 2015. Total Population is the total number of residents in an area. Residence refers to the "usual place" where a person lives. This data variable is included in Esri's Updated Demographics (2010/2015). This map shows Esri's 2010 estimates using Census 2000 geographies. The map is designed to be displayed with 30–50 percent semi-transparency for overlay on other basemaps as noted in the map legend. A basemap with relatively few colors, such as Terrain, works well with this map when transparency is used. A web map that combines this service with the Terrain basemap and a reference overlay for...

Implementing conservation in the face of unprecedented landscape change requires an understanding of processes and scales that limit wildlife populations. We assessed landscape-level processes influencing sage-grouse (Centrocercus urophasianus), to a migratory population in the Milk River Basin (MRB), northeast Montana, USA, and south-central Saskatchewan, Canada. A regional analysis of leks (e.g., communal breeding sites) documented that populations impacted by the increasing extent of agricultural tillage, roads, and energy development out to spatial scales larger than previously known. Using bird abundance as a novel way to evaluate human impacts revealed relationships that would have been missed had we not incorporated...

Freshwater mussels (unionids) are increasingly recognized as important providers of ecosystem services, yet are among the most endangered fauna in the world. Because unionids are generally sessile and require specific fish hosts for development and dispersal, they are particularly vulnerable to habitat degradation. Surprisingly, little is known about the distribution of genetic diversity in freshwater mussels and this gap has a negative impact on taxonomy, monitoring, conservation and ecological research in these species. Here, we focus on western North American Anodonta, one of only three genera known to exist in this broad landscape and which contains three highly divergent lineages. We describe phylogeographical...

We examined survival rates of mule deer (Odocoileus hemnionus) fawns (1 Jan-31 May) and adult (21 yr old) females (1 Jun-31 May) from Colorado, Idaho, and Montana to assess the influence of survival on population dynamics over a broad geographic area. Survival rates were estimated from 1,875 radiocollared fawns and 1,536 radiocollared adult female-years. We found significant year-to-year differences in overwinter survival rates of fawns among states (P < 0.001), while annual survival rates of adult females showed less variation across years (P < 0.256). Sampling distributions of survival rates bv age class were modeled with the beta-binomial distribution (BBD) and not found different among states (ad F: P = 0.118;...

This child page contains county population estimates from the USCB for New Mexico and Texas, 1980-2019. The data was utilized as input data for the model associated with the Scientific Investigations Report "Estimates of Water Use Associated with Continuous Oil and Gas Development in the Permian Basin, Texas and New Mexico, 2010–2019" (Valder and others, 2021). All data points that met the filtering criteria as described in the Data Processing <procdesc> steps were retained in the data release. Further filtering of data points to remove unrealistic values was done prior to modeling. The model was used to estimate water use associated with continuous oil and gas development in the Permian Basin, Texas and New Mexico,...

Reliable information concerning where water is used, how water is used, the quantity of water used, and changes in water use over time is key in making informed water-resources management decisions. Although projections of water-use estimates are subject to a variety of contingencies, ranging from natural disasters such as droughts and floods to economic booms or disruptions, they provide a basis for planners to evaluate the adequacy of water resources to meet future needs. During 2007, the State of Tennessee experienced a drought that limited water supply to several of the utility systems. As a result, the U.S. Geological Survey (USGS), in cooperation with the Tennessee Department of Environment and Conservation,...
In the Great Plains, climate change is expected to result in more frequent and intense droughts, severe rainfall events, and heat waves. Adapting to changing conditions will require coordination in the research and observation capabilities of multiple organizations, institutions, and government programs. In light of these needs, researchers worked with federal, state, tribal, university, and non-governmental organization partners to (1) synthesize the current state of ecosystems in the Great Plains; (2) assess the ability of human and ecological communities in the region to adapt to climate change; and (3) develop a process to improve future assessments of the vulnerability of the region’s natural and cultural resources...

Developed by the Oak Ridge National Laboratory (ORNL), the LandCast 2050 High-Resolution Population Projection models future national-level human population densities. The models estimate the probability of a population being at a particular location, which measures where people will likely be in the future, not necessarily their places of residence.The LandCast 2050 data set is an empirically-informed spatial distribution of projected population of the contiguous U.S. for 2050 compiled on a 30” x 30” latitude/longitude grid. Population projections of county level numbers were developed using a modified version of the U.S. Census’ projection methodology-with the U.S. Census’ official projection as the benchmark....

This study set out to answer the question: “What data and modeling frameworks are needed to provide scientists reliable, climate-informed, water temperature estimates for freshwater ecosystems that can assist watershed management decision making?” To accomplish this, the study gathered existing stream temperature data, identified data gaps, deployed stream temperature monitoring devices, and developed and tested a stream temperature model that could be regionalized across the Northeast domain. We partnered with another funded project team, led by Jana Stewart at WI USGS to collect data from over 10,000 locations across the climate science center domain. This collection effort aided in identifying data gaps where...
