Microhabitat selection of brood-rearing sites by greater sage-grouse in Carbon County, Wyoming

Creator:: Schreiber, Leslie A.
Abstract:: Declines in Greater Sage-Grouse (Centrocercus urophasianus, hereafter sage-grouse) populations could be attributed to low chick survival, which may be influenced by the availability of food and cover at sites used by females rearing broods. Habitat attributes important to broods may vary regionally; thus, it is necessary to understand factors affecting...

Responses contribute to context effects on ratio-setting timing tasks

Creator:: Ryan, Lawrence J. and Havens, Anthony
Abstract:: Short durations in a range of standard durations are typically overreproduced and long durations underreproduced (‘Vierordt’s Law’). This contextual distortion may result from each trial assimilating the central tendency of the preceding series. We examine whether responses as well as standard durations contribute to this distortion. Two experiments using nonequal-setting...

Microsporidiosis in zebrafish research facilities

Creator:: Sanders, Justin L., Watral, Virginia, and Kent, Michael L.
Abstract:: Pseudoloma neurophilia (Microsporidia) is the most common pathogen detected in zebrafish (Danio rerio) from research facilities. The parasite infects the central nervous system and muscle, and may be associated with emaciation and skeletal deformities. However, many fish exhibit subclinical infections. Another microsporidium, Pleistophora hyphessobryconis, has recently been detected in a...

Dynamics of coastal meta-ecosystems: the intermittent upwelling hypothesis and a test in rocky intertidal regions

Abstract:: The intermittent upwelling hypothesis (IUH) predicts that the strength of ecological subsidies, organismal growth responses, and species interactions will vary unimodally along a gradient of upwelling from persistent downwelling to persistent upwelling, with maximal levels at an intermediate or ‘‘intermittent’’ state of upwelling. To test this model, we employed the...

Phenol formaldehyde adhesives formulated for advanced x-ray imaging in wood-composite bondlines

Creator:: Paris, Jesse L., Kamke, Frederick A., Mbachu, Reginald, and Gibson, Sara Kraushaar
Abstract:: A phenol formaldehyde (PF) adhesive was uniformly tagged with iodine such that it yielded sufficient x-ray computed tomography (XCT) gray-scale contrast for material segmentation in reconstructed wood-composite bondlines. Typically, untagged adhesives are organic and have a similar solid state density as wood cell-walls, and therefore cannot be segmented quantitatively in...

Environmental Value Considerations in Public Attitudes About Alternative Energy Development in Oregon and Washington

Creator:: Steel, Brent S., Pierce, John C., Warner, Rebecca L., and Lovrich, Nicholas P.
Abstract:: The 2013 Pacific Coast Action Plan on Climate and Energy signed by the Governors of California, Oregon and Washington and the Premier of British Columbia, launched a broadly announced public commitment to reduce greenhouse gas emissions through multiple strategies. Those strategies include the development and increased use of renewable energy...

Housing Prices and Inter-urban Migration

Creator:: Plantinga, Andrew J., Detang-Dessendre, Cécile, Hunt, Gary L., and Piguet, Virginie
Abstract:: Economic theory predicts that individual migration decisions for working-age adults will depend on area differences in wages, housing costs, and amenities. While the importance of wages and amenities is well-established from previous empirical studies, evidence regarding housing costs is far less conclusive. We develop and test a new method for...

S., Liberzon, D., Massey, J. D., McEnerney, K., Pal, S., Price, T., Sghiatti, M., Silver, Z., Thompson, M., Zhang, H., and Zsedrovits, T.
Abstract:: Emerging application areas such as air pollution in megacities, wind energy, urban security, and operation of unmanned aerial vehicles have intensified scientific and societal interest in mountain meteorology. To address scientific needs and help improve the prediction of mountain weather, the U.S. Department of Defense has funded a research effort—the...
