Habitat selection by Greater Sage-Grouse during winter in southeastern Oregon

Creator:: Hagen, Christian A., Willis, Mitchell J., Glenn, Elizabeth M., and Anthony, Robert G.
Abstract:: The distribution and geographic range of Greater Sage-Grouse (Centrocercus urophasianus) have been reduced by 56% since European settlement. Although loss and fragmentation of sagebrush (Artemisia spp.) habitats have been cited as the primary causes for the decline of the species, degradation of existing habitat also has been considered an important...

Size-structured spatial patterns as a measure of larval dispersal and emigration

Creator:: Markle, Douglas F.
Abstract:: Size-structured spatial patterns in larvae of 2 sucker and 3 minnow species are described from fixed-site sampling in Upper Klamath Lake, Oregon, and are used to demonstrate patterns of size-based losses downstream and retention in the lake. The smallest larvae of shortnose suckers (Chasmistes brevirostris), Lost River suckers (Deltistes luxatus),...

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...

Greater Sage-Grouse movements and habitat use during winter in central Oregon

Creator:: Bruce, Jennifer R., Robinson, W. Douglas, Petersen, Steven L., and Miller, Richard F.
Abstract:: Greater Sage-Grouse (Centrocercus urophasianus) depend on sagebrush habitat for food and cover during winter, yet few sage-grouse winter ecology studies have been conducted. During January and February 2007, we monitored 22 radio-collared sage-grouse (7 females and 15 males) in central Oregon to characterize winter habitat use and movement patterns. We...

Medusahead Invasion Along Unimproved Roads, Animal Trails, and Random Transects

Creator:: Davies, Kirk W., Nafus, Aleta M., and Madsen, Matthew D.
Abstract:: Medusahead (Taeniatherum caput-medusae [L.] Nevski), an exotic annual grass, is rapidly spreading and causing ecological damage across the western United States. Because this exotic plant occupies vast areas and because management resources are limited, it is critical that land managers prioritize where they direct treatment and monitoring efforts. Identifying where...

G : a language based on demand-driven evaluation of streams

Creator:: Oregon State University. Dept. of Computer Science, Budd, Timothy, and Placer, John
Abstract:: The language G is an expression based language designed around the concept of the stream; where a stream is a sequence of values, perhaps infinite in length. There are no statements in G, only expressions. All expressions are evaluated on a demand driven basis, no computation takes place that does...

Large wildlife removal drives immune defence increases in rodents

Creator:: Young, Hillary S., Dirzo, Rodolfo, Helgen, Kristofer M., McCauley, Douglas J., Nunn, Charles L., Snyder, Paul, Veblen, Kari E., Zhao, Serena, and Ezenwa, Vanessa O.
Abstract:: 1. Anthropogenic disturbances involving land use change, climate disruption, pollution and invasive species have been shown to impact immune function of wild animals. These immune changes have direct impacts on the fitness of impacted animals and, also, potentially indirect effects on other species and on ecological processes, notably involving the...

Age systematics of two young en echelon Samoan volcanic trails

Creator:: Koppers, Anthony A. P., Russell, Jamie A., Roberts, Jed, Jackson, Matthew G., Konter, Jasper G., Wright, Dawn J., Staudigel, Hubert, and Hart, Stanley R.
Abstract:: The volcanic origin of the Samoan archipelago can be explained by one of three models, specifically, by a hot spot forming over a mantle plume, by lithospheric extension resulting from complex subduction tectonics in the region, or by a combination of these two processes, either acting sequentially or synchronously. In...

Fingered Flow in Two Dimensions 2. Predicting Finger Moisture Profile

Creator:: Selker, J., Parlange, J.-Y., and Steenhuis, T.
Abstract:: An exact integral solution for the moisture profile in growing fingers in sandy soil is derived from Richards' equation. The solution provides moisture content along a finger as a function of position and time and provides applicable results, including the calculation of the asymptotic matric potential of a growing finger...

Abstract:: The protein palmitoylation cycle has been shown to be important for protein signaling and synaptic plasticity. Data from our lab showed a change in the palmitoylation status of certain proteins with age. A greater percentage of the NMDA receptor subunits GluN2A and GluN2B, along with Fyn and PSD95 proteins, were...

Informative g-Priors for Logistic Regression

Creator:: Hanson, Timothy E., Branscum, Adam J., and Johnson, Wesley O.
Abstract:: Eliciting information from experts for use in constructing prior distributions for logistic regression coefficients can be challenging. The task is especially difficult when the model contains many predictor variables, because the expert is asked to provide summary information about the probability of “success” for many subgroups of the population. Often,...

Low Concentrations of Bisphenol A Induce Mouse Spermatogonial Cell Proliferation by G Protein–Coupled Receptor 30 and Estrogen Receptor-α

Creator:: Sheng, Zhi-Guo and Zhu, Ben-Zhan
Abstract:: BACKGROUND: Bisphenol A (BPA) is one of the most prevalent chemicals in daily-use materials; therefore, human exposure to BPA is ubiquitous. The estrogenicity of BPA is generally mediated by nuclear estrogen receptors (ERs). However, low concentrations of BPA stimulate seminoma cell proliferation by an uncertain mechanism that does not involve...

Assessment of thermal embrittlement in duplex stainless steels 2003 and 2205 for nuclear power applications

Creator:: Tucker, J. D., Miller, M. K., and Young, G. A.
Abstract:: Duplex stainless steels are desirable for use in power generation systems because of their attractive combination of strength, corrosion resistance and cost. However, thermal embrittlement at intermediate homologous temperatures of ~475 °C and below, limits upper service temperatures for many applications. New lean grade duplex alloys have improved thermal stability...

Is malaria illness among young children a cause or a consequence of low socioeconomic status? evidence from the united Republic of Tanzania

Creator:: de Castro, Marcia Caldas and Fisher, Monica G
Abstract:: Background: Malaria is commonly considered a disease of the poor, but there is very little evidence of a possible two-way causality in the association between malaria and poverty. Until now, limitations to examine that dual relationship were the availability of representative data on confirmed malaria cases, the use of a...

Bird-vegetation associations in thinned and unthinned young Douglas-fir forests 10 years after thinning

Creator:: Yegorova, Svetlana, Betts, Matthew G., Hagar, Joan, and Puettmann, Klaus J.
Abstract:: Quantitative associations between animals and vegetation have long been used as a basis for conservation and management, as well as in formulating predictions about the influence of resource management and climate change on populations. A fundamental assumption embedded in the use of such correlations is that they remain relatively consistent...
