This dataset is a compilation of forest insect, disease and abiotic damage mapped by aerial detection surveys on forested areas in the United States. At this time, the National Aerial Survey Data Standards require only mortality and defoliation data be collected and reported. However, many cooperators collect data on other types of damage and therefore, the national database has been designed to accommodate these data. Low-level flights, typically 1,000 to 2,000 feet above ground level, are used to map forest damage. Observers use paper maps, typically 1:100,000 scale USGS maps, upon which they record the damage. There is also a digital sketchmap system that may be used. The digital system uses GPS to display the...

The Sqigwts 3-D Landscape is an interactive three-dimensional experience developed to provide an opportunity to effectively learn about the important cultural significance of sqigwts, the water potato (Sagittaria latifolia), to the Schitsu’umsh or Coeur d’Alene Indian Tribe (of the Pacific Northwest USA). The goal is to provide information on the potential vulnerability of this species to climate change and of the Schitsu’umsh living relationship with it. Schitsu’umsh knowledge and practice is called hnkhwelkhwlnet, meaning “our ways of life in the world,” and is conveyed through acts of re-telling oral traditions and stories. For the Schitsu’umsh, storytelling is a living act and can only truly occur in-person...

This release is for data on Zinc concentrations and isotopic signatures of an aquatic insect (mayfly, Baetis tricaudatus). Mayflies were exposed to an aqueous zinc concentration gradient in a laboratory experiment. Zinc concentrations were measured in water, algae (mayfly food), and different mayfly lifestages. Natural abundances of carbon and nitrogen isotopes were also measured in different life stages. This data set includes on Zinc data. Isotope data are provided in a separate file. The abstract for a journal article explaining the results of the experiment follows below: Insect metamorphosis often results in substantial chemical changes that can fractionate isotopes and alter contaminant concentrations. We...

Splits of samples were prepared of heavy mineral separates and bulk separates less than 2mm for analysis using X-ray diffraction (XRD) and results were interpreted to identify mineral components as part of a study examining the occurrence of chromium and natural and anthropogenic hexavalent Chromium, Cr(VI), in groundwater. Data will be used to estimate naturally-occurring background Cr(VI) concentrations upgradient, near the plume margins, and downgradient from a mapped Cr(VI) contamination plume near Hinkley, CA (Izbicki and Groover, 2016). These XRD results are part of a data release including grain size distribution, photographic, and associated chemical and mineral analysis data for 36 sediment core and alluvium...
Geothermal energy, carbon sequestration, and enhanced oil and gas recovery have a clear role in U.S. energy policy, both in securing cost-effective energy and reducing atmospheric CO2 accumulations. Recent publicity surrounding induced seismicity at several geothermal and oil and gas sites points out the need to develop improved standards and practices to avoid issues that may unduly inhibit or stop the above technologies from fulfilling their full potential. It is critical that policy makers and the general community be assured that EGS, CO2 sequestration, enhanced oil/gas recovery, and other technologies relying on fluid injections, will be designed to reduce induced seismicity to an acceptable level, and be developed...
As the United States moves closer to a national climate change policy, it will have to focus on a variety of factors affecting the manner in which the country moves toward a future with a substantially lower carbon footprint. In addition to encouraging renewable energy, smart grid, clean fuels and other technologies, the United States will need to make substantial infrastructure investments in a variety of industries. Among the significant contributors to the current carbon footprint in the United States is the use of coal as a major fuel for the generation of electricity. One of the most important technologies that the United States can employ to reduce its carbon footprint is to sequester the carbon dioxide ("CO2")...

Societal concerns about the social and environmental impacts of biofuel production are driving producers to adopt better management practices. Existing certification schemes for sustainable biofuel production are, however, biased towards industrial-scale producers that have the financial capital and economies of scale to meet sustainability and certification objectives. Smallholder farmers in developing countries, by contrast, often lack the means and capacity to do so. Some of the challenges faced by smallholders include high certification costs, insufficient institutional capacity, inadequate financial and social incentives, poor group organization and lack of external support. Drawing lessons from existing certification...

This paper addresses two questions concerning the economics and prospects for nuclear power in the USA: 1) What is the long term economic future of nuclear energy? 2) Is the inability to solve the nuclear waste issue a factor that will limit new nuclear plant development? With respect to the first question, we find that the long term economic future of nuclear energy is uncertain, at best. Despite recent interest in a “nuclear renaissance,” objective, rigorous studies have concluded that, at present, new nuclear power plants are not economically competitive with coal or natural gas for electricity generation and will not be for the foreseeable future. With respect to the second question, we find that the inability...

Species loss can result in the subsequent loss of affiliate species. Though largely ignored to date, these coextinctions can pose threats to human health by altering the composition, quantity and distribution of zoonotic parasites. We simulated host extinctions from more than 1300 host–parasite associations for 29 North American carnivores to investigate changes in parasite composition and species richness. We also explored the geography of zoonotic parasite richness under three carnivore composition scenarios and examined corresponding levels of human exposure. We found that changes in parasite assemblages differed among parasite groups. Because viruses tend to be generalists, the proportion of parasites that are...

The Blueprint 2.2 Development Process is a final report that explains in detail how the Conservation Blueprint was created. It first provides an overview of the South Atlantic LCC and the Blueprint framework, then combines the metadata available on the Conservation Planning Atlas for all ecosystem maps, ecosystem indicators, ecosystem scores, corridors, and final Blueprint priorities. It is intended to serve as a comprehensive guide to the Blueprint objectives, data sources, and methodology that could enable an interested reader to reproduce the Blueprint independently.
