Toxicity Of Manufactured Particulate Materials On Plant Root Growth, Ling Yang Aug 2004

Toxicity Of Manufactured Particulate Materials On Plant Root Growth, Ling Yang

Dissertations

The rapid development of particle technology and the growing use of particulate materials in industries are bringing large amounts of manufactured particles into the environment. Epidemiological studies suggest that fine particles (particles with aerodynamic diameter smaller than 2.5 μm, i.e., PM2.5) have an association with various adverse health effects in humans. Mass studies have been performed on the toxicity and toxicological mechanisms of airborne particles such as PM2.5 and PM10, but there are very few investigations which contribute to the knowledge base on biological implications of manufactured particulate materials. Up to now, the published toxicity …

Identification And Characterization Of Phosphoseryl-Trna [Ser]Sec Kinase, Bradley A. Carlson, Xue-Ming Xu, Gregory V. Kryukov, Mahadev Rao, Marla J. Berry, Vadim N. Gladyshev, Dolph L. Hatfield Aug 2004

Identification And Characterization Of Phosphoseryl-Trna [Ser]Sec Kinase, Bradley A. Carlson, Xue-Ming Xu, Gregory V. Kryukov, Mahadev Rao, Marla J. Berry, Vadim N. Gladyshev, Dolph L. Hatfield

Vadim Gladyshev Publications

In 1970, a kinase activity that phosphorylated a minor species of seryl-tRNA to form phosphoseryl-tRNA was found in rooster liver [Maenpaa, P. H. & Bernfield, M. R. (1970) Proc. Natl. Acad. Sci. USA 67, 688–695], and a minor seryl-tRNA that decoded the nonsense UGA was detected in bovine liver. The phosphoseryl-tRNA and the minor UGA-decoding seryl-tRNA were subsequently identified as selenocysteine (Sec) tRNA [Ser]Sec, but the kinase activity remained elusive. Herein, by using a comparative genomics approach that searched completely sequenced archaeal genomes for a kinase-like protein with a pattern of occurrence similar to that of components of Sec …

The Use Of Bauxite Residue To Control Diffuse Phosphorus Pollution In Western Australia – A Win-Win-Win Outcome, Robert Summers, Mark Rivers, Martin Clarke Aug 2004

The Use Of Bauxite Residue To Control Diffuse Phosphorus Pollution In Western Australia – A Win-Win-Win Outcome, Robert Summers, Mark Rivers, Martin Clarke

Conference papers and presentations

The Department of Agriculture, Western Australia has been working with Alcoa World Alumina Australia Ltd for more than ten years investigating the potential to use bauxite refining residues as soil amendments for the poor, acidic, sandy soils of the Swan Coastal Plain in south west Australia. Regional waterways, especially the Peel Inlet and Harvey Estuary, have historically been susceptible to nuisance algal blooms fed by phosphorus in run-off from farmland and urban areas. Extensive laboratory, field and catchment-scale trials have shown the ability of soil amendment with fine bauxite refining residue (now trademarked in this context as Alkaloam™) to reduce …

Population Level Survey Of Golden Eagles (Aquila Chrysaetos) In The Western United States, Rhett E. Good, Ryan M. Nielson, H. Hall Sawyer, Lyman L. Mcdonald Aug 2004

Population Level Survey Of Golden Eagles (Aquila Chrysaetos) In The Western United States, Rhett E. Good, Ryan M. Nielson, H. Hall Sawyer, Lyman L. Mcdonald

United States Fish and Wildlife Service: Publications

Some researchers have suggested Golden Eagle (Aquila chrysaetos) populations may be declining in at least part of their range (Bittner and Oakley 1999, Leslie 1992, Steenhof et al. 1997). However, there are little baseline data describing Golden Eagle populations across their range in the western United States (U.S.). The United States Geological Survey (USGS) Snake River Field Station recently prepared a preliminary plan for monitoring Golden Eagle populations (Fuller et al. 2001). Based on recommendations by Fuller et al. (2001), the United States Fish and Wildlife Service (USFWS) issued a request for proposals (Solicitation number 982103R041) to design …

Woodland Amphibian Distribution In Parks And Greenspaces Of The Portland, Oregon Metropolitan Area: A Multiple Scale Investigation, Laura A. Roberts Aug 2004

Woodland Amphibian Distribution In Parks And Greenspaces Of The Portland, Oregon Metropolitan Area: A Multiple Scale Investigation, Laura A. Roberts

Dissertations and Theses

Loss of biodiversity due to habitat fragmentation is worldwide problem. With growing human populations and increasing urbanization, it is a necessity to conduct studies on wildlife occurring in urban areas. Currently there is a deficit of research investigating woodland amphibians in urban environments. My objectives were to describe amphibian species richness and abundance in the Portland, Oregon, Metropolitan region, and relate patterns of variation to variables at three increasingly large spatial scales: 1) local microenvironmental (i.e. amphibian/substrate interaction), (2) macrohabitat/patch (i.e. park or greenspace), and 3) landscape (surrounding parks and greenspaces). Environmental variables occurring within the three spatial scales were …

Analyses Of The Spring Dust Storm Frequency Of Northern China In Relation To Antecedent And Concurrent Wind, Precipitation, Vegetation, And Soil Moisture Conditions, Xiaodong Liu, Zhi-Yong Yin, Xiaoye Zhang, Xuchao Yang Aug 2004

Analyses Of The Spring Dust Storm Frequency Of Northern China In Relation To Antecedent And Concurrent Wind, Precipitation, Vegetation, And Soil Moisture Conditions, Xiaodong Liu, Zhi-Yong Yin, Xiaoye Zhang, Xuchao Yang

Environmental and Ocean Sciences: Faculty Scholarship

The relationships between the spring (March–May) dust storm frequency (DSF) of northern China, gridded precipitation based on gauge observations, wind velocity at different geopotential heights, satellite-measured land vegetation index, and grid box soil moisture data during 1982–2001 are examined using correlation analysis and singular value decomposition methods. The results show that the spring DSF time series has strong positive correlations with the upwind wind velocity but strong negative correlations with the antecedent summer (June–August) and annual (June of the prior year to May of the current year) precipitation and soil moisture anomalies, as well as with the spring vegetation condition …

Synergisms Of Electric Or Electromagnetic Fields And Photodynamic Effects Induce Apoptosis And Necrosis Of Cancer Cells, Radeva Maria, Lambrera Maya, Angelova Plamena, Traitcheva Nelly, Berg Hermann Aug 2004

Synergisms Of Electric Or Electromagnetic Fields And Photodynamic Effects Induce Apoptosis And Necrosis Of Cancer Cells, Radeva Maria, Lambrera Maya, Angelova Plamena, Traitcheva Nelly, Berg Hermann

Journal of Electrochemistry

Weak pulsating sinusoidal electromagnetic fields (PEMF) have been applied to change membrane permeation and induction of apoptosis (necrosis). In the case of suspension of human cancer cells U-937 and K-562 inside of Helmholtz-coils the amplitude of PEMF B=10 and at 39mT (at 50 Hz) was combined gradually with the cytotoxic agent actinomycin-C on one hand with its novel photodynamic activity on the other.

Fleas (Siphonaptera) In Nests Of Voles (Microtus Spp.) In Montane Habitats Of Three Regions Of Utah, Glenn E. Haas, James R. Kucera Aug 2004

Fleas (Siphonaptera) In Nests Of Voles (Microtus Spp.) In Montane Habitats Of Three Regions Of Utah, Glenn E. Haas, James R. Kucera

Western North American Naturalist

As a parallel study of a survey of fleas of trapped small mammals in montane southern Utah, we removed 77 adult fleas from 12 of 13 nests of voles (Microtus longicaudus, M. montanus and M. richardsoni) collected from montane meadows in the Abajo and La Sal Mountains, the Markagunt Plateau and Pine Valley Mountains, and the Uinta Mountains, May 1991–July 2002. Six species and subspecies of fleas parasitic on Microtus spp. were found, 1–3 species in each nest. Three specimens of the ubiquitous deer mouse (Peromyscus spp.) flea Aetheca wagneri (Baker) were also found. We collected the …

Vegetation Response To Fire And Postburn Seeding Treatments In Juniper Woodlands Of The Grand Staircase–Escalante National Monument, Utah, Paul Evangelista, Thomas J. Stohlgren, Debra Guenther, Sean Stewart Aug 2004

Vegetation Response To Fire And Postburn Seeding Treatments In Juniper Woodlands Of The Grand Staircase–Escalante National Monument, Utah, Paul Evangelista, Thomas J. Stohlgren, Debra Guenther, Sean Stewart

Western North American Naturalist

We compared 3 naturally ignited burns with unburned sites in the Grand Staircase–Escalante National Monument. Each burn site was restored with native and nonnative seed mixes, restored with native seeds only, or regenerated naturally. In general, burned sites had significantly lower native species richness (1.8 vs. 2.9 species), native species cover (11% vs. 22.5%), and soil crust cover (4.1% vs. 15%) than unburned sites. Most burned plots, seeded or not, had significantly higher average nonnative species richness and cover and lower average native species richness and cover than unburned sites. Regression tree analyses suggest site variation was equally important to …

Using Sampling And Inverse Distance Weighted Modeling For Mapping Invasive Plants, Elizabeth A. Roberts, Roger L. Sheley, Rick L. Lawrence Aug 2004

Using Sampling And Inverse Distance Weighted Modeling For Mapping Invasive Plants, Elizabeth A. Roberts, Roger L. Sheley, Rick L. Lawrence

Western North American Naturalist

Accurate time- and cost-efficient mapping is central to successful rangeland invasive plant management. In this study sampling together with Inverse Distance Weighted (IDW) interpolation modeling was tested as a mapping alternative to expensive full-coverage delineation survey mapping methods. Our objective was to examine accuracies of presence/absence maps generated from 18 sampling strategies (3 sampling methods × 6 sample densities) using IDW. Invasive plant field survey maps with known accuracies were used to generate samples and to test interpolation results at 2 sites. Site 1 was approximately 6.0 km2, dominated by Russian knapweed (Acroptilon repens L.). Site 2, …

Observations Of Sagebrush Gall Morphology And Emergence Of Rhopalomyia Pomum (Diptera: Cecidomyiidae) And Its Parasitoids, Ruth A. Hufbauer Aug 2004

Observations Of Sagebrush Gall Morphology And Emergence Of Rhopalomyia Pomum (Diptera: Cecidomyiidae) And Its Parasitoids, Ruth A. Hufbauer

Western North American Naturalist

Galls induced by insects are specialized plant tissues thought to provide a suitable microclimate and high-quality food for insect development. Galls are also hypothesized to provide protection from predators, and particularly from parasitoids, because larger galls may be too deep for parasitoid oviposition (enemies hypothesis). However, galls may actually increase the risk of parasitism by making the location of gallformers more apparent (apparency hypothesis). Rhopalomyia pomum (Diptera: Cecidomyiidae) forms soft, lobed galls on big sagebrush (Artemisia tridentata: Asteraceae). The volume of the largest galls can be 600× that of the smallest. Here I explore the relationships of the …

Survival Rates Of Translocated And Native Mountain Quail In Oregon, Michael D. Pope, John A. Crawford Aug 2004

Survival Rates Of Translocated And Native Mountain Quail In Oregon, Michael D. Pope, John A. Crawford

Western North American Naturalist

We estimated survival rates for 232 radio-tagged native (n = 157) and translocated (n = 75) Mountain Quail (Oreortyx pictus) from 1997 to 1999 in Hells Canyon National Recreation Area (HCNRA) in northeastern Oregon and in the Cascade Mountain Range (CMR) of southwestern Oregon. For the combined areas the estimated survival rate during 150-day intervals was 0.42 ± 0.04. Estimated survival was 0.41 ± 0.04 for Mountain Quail in HCNRA and 0.34 ± 0.34 for quail in CMR. There were no differences in survival functions for native quail in HCNRA and CMR (P = 0.91), …

Seasonal Habitat Use And Selection Of Chukars In West Central Idaho, Andrew J. Lindbloom, Kerry P. Reese, Peter Zager Aug 2004

Seasonal Habitat Use And Selection Of Chukars In West Central Idaho, Andrew J. Lindbloom, Kerry P. Reese, Peter Zager

Western North American Naturalist

We examined radio-marked Chukar (Alectoris chukar) habitat use and selection in west central Idaho during spring and summer of 1995 and 1996. Use of habitats also was compared with abundance and distribution of yellow starthistle (Centaurea solstitialis), an exotic species that is increasingly abundant in Chukar habitats. During summer Chukars used areas of southeast aspect 12% less (P = 0.002) and areas of northwest aspect 11% more (P = 0.008) than in spring. Chukars also used areas that averaged 9% steeper slopes (P < 0.001) and 83 m lower elevations (P = 0.054) in summer than in spring. Shrub cover …

Host-Based Morphometric Differentiation In Three Cinara Species (Insecta: Hemiptera: Aphididae) Feeding On Pinus Edulis And P. Monophylla, Colin Favret, David J. Voegtlin Aug 2004

Host-Based Morphometric Differentiation In Three Cinara Species (Insecta: Hemiptera: Aphididae) Feeding On Pinus Edulis And P. Monophylla, Colin Favret, David J. Voegtlin

Western North American Naturalist

Cinara edulis (Wilson), C. terminalis (Gillette and Palmer), and C. wahtolca Hottes were all larger when feeding on Pinus monophylla Torr. & Frem. than when feeding on P. edulis Engelm. Almost all nonsetal morphometric characters were longer in aphids on the former of these pinyon pines. Although mouthpart characters also followed this pattern of size in C. edulis and C. wahtolca, rostrum length showed the opposite pattern in C. terminalis and was shorter when on P. monophylla. This reversal in size pattern suggests that mouthpart size can be independent of overall aphid size. Principal components analyses corroborate the …

Comparative Habitat Use In A Juniper Woodland Bird Community, David C. Pavlacky Jr., Stanley H. Anderson Aug 2004

Comparative Habitat Use In A Juniper Woodland Bird Community, David C. Pavlacky Jr., Stanley H. Anderson

Western North American Naturalist

We compared vegetation structure used by 14 bird species during the 1998 and 1999 breeding seasons to determine what habitat features best accounted for habitat division and community organization in Utah juniper (Juniperus osteosperma) woodlands of southwestern Wyoming. Habitat use was quantified by measuring 24 habitat variables in 461 bird-centered quadrats, each 0.04 ha in size. Using discriminant function analysis, we differentiated between habitat used by 14 bird species along 3 habitat dimensions: (1) variation in shrub cover, overstory juniper cover, mature tree density, understory height, and decadent tree density; (2) a gradient composed of elevation and forb …

Passerine Response To Roads Associated With Natural Gas Extraction In A Sagebrush Steppe Habitat, Franz Ingelfinger, Stanley Anderson Aug 2004

Passerine Response To Roads Associated With Natural Gas Extraction In A Sagebrush Steppe Habitat, Franz Ingelfinger, Stanley Anderson

Western North American Naturalist

Natural gas extraction and field development are pervasive throughout the sagebrush steppe of Wyoming. We conducted this study to determine how roads associated with natural gas extraction affect the distribution of breeding songbirds in sagebrush steppe habitat. The study encompassed dirt and paved roads in the Jonah Field II and Pinedale Anticline Project Area in Sublette County, Wyoming. Sites are dominated by Wyoming big sagebrush (Artemisia tridentata), and common passerines include sagebrush obligates: Brewer's Sparrows (Spizella breweri), Sage Sparrows (Amphispiza belli), and Sage Thrashers (Oreoscoptes montanus); and non-obligates: Horned Larks (Eremophila …
