Predicting The Impact Of Climate Change On Cheat Grass (Bromus Tectorum) Invasibility For Northern Utah: A Gis And Remote Sensing Approach, Samuel Rivera, Neil E. West, Alexander J. Hernandez, R. Doug Ramsey

Natural Resources and Environmental Issues

Cheat grass (Bromus tectorum) invasibility represents a serious threat to natural ecosystems dominated by sagebrush (Artemisia tridentata). Ecosystem susceptibility to annual grass invasion seems to be driven by specific biophysical conditions. The study was conducted in Rich County, Utah, where cheat grass invasion is not yet an apparent problem, but an imminent invasion might be just a matter of time (temporal scale) to meet spatial variations in environmental conditions (spatial scale). Literature review and expert knowledge were used to define biophysical variables and their respective suitability ranges of where cheat grass takeover might occur. GIS, remote sensing and logistic regression-statistical …

Associations Of Near-Surface Soil Moisture And Annual Plant Community Dynamics, Lauren P. Ducas, Scott B. Jones, A. Joshua Leffler, Ronald J. Ryel

Natural Resources and Environmental Issues

Invasive species have become an increasingly large concern, particularly in already degraded ecosystems, such as sagebrush (Artemisia tridentata)-steppe of the Intermountain West. Much of this ecosystem is already infested with large cheatgrass (Bromus tectorum) stands and is potentially at risk for future invasions depending on biotic and abiotic conditions. In these ecosystems, the existing vegetation, whether native or non-native, may not effectively utilize the soil moisture resources in the upper portion of the soil, termed the growth pool. If the existing vegetation does not effectively utilize moisture in the growth pool, an open resource is left for the establishment of …

Morphological And Physiological Traits Account For Similar Nitrate Uptake By Crested Wheatgrass And Cheatgrass, A. Joshua Leffler, Thomas A. Monaco, Jeremy J. James

Natural Resources and Environmental Issues

Millions of hectares throughout the Intermountain West are either dominated or threatened by the invasive annual grass Bromus tectorum (cheatgrass). This invasion is largely linked to disturbance and few regions appear immune. Disturbance liberates resources in a community and cheatgrass appears exceptionally able to capitalize on these resources. One species, however, is consistently competitive with cheatgrass. Agropyron cristatum (crested wheatgrass), an improved plant material developed from several populations in central Asia, is drought resistant, grazing tolerant, and largely excludes cheatgrass in stands established within the Great Basin. While previous studies document high resource uptake ability by crested wheatgrass, it remains …

Potential Impacts Of Energy Development On Shrublands In Western North America, Amy Pocewicz, Holly Copeland, Joseph Kiesecker

Natural Resources and Environmental Issues

Impending rapid development of the abundant energy resources found in western North America may have dramatic consequences for its terrestrial ecosystems. We used lease and license data to provide an approximate estimate of direct and indirect potential impacts from renewable and non-renewable energy development on each of five major terrestrial ecosystems and completed more detailed analyses for shrubland ecosystems. We found that energy development could impact up to 21 percent (96 million ha) of the five major ecosystems in western North America. The highest overall predicted impacts as a percent of the ecosystem type are to boreal forest (23-32 percent), …

Estimating Historical Sage-Grouse Habitat Abundance Using A State-And-Transition Model, Louisa Evers, Richard F. Miller, Miles Hemstrom, James Merzenich, Ronald Neilson, Paul Doescher

Natural Resources and Environmental Issues

Use of reference conditions to compare current conditions what managers believed represented healthy and functioning systems has become a common approach to evaluate vegetation and habitat conditions and aid development of land management plans. Often reference conditions attempt to describe landscapes as they existed and functioned prior to about 1850, and often largely rely on expert opinion. We developed reference conditions for sagebrush (Artemisia spp. L.) ecosystems in eastern Oregon based on ecological site descriptions, soil surveys, climate data, wildfire records, expert opinion, and literature using a state-and-transition (STM) modeling framework. Using ecological site descriptions for the Malheur High Plateau …

Native Annual Plant Response To Fire: An Examination Of Invaded, 3 To 29 Year Old Burned Creosote Bush Scrub From The Western Colorado Desert, Robert J. Steers, Edith B. Allen

Natural Resources and Environmental Issues

Creosote bush scrub vegetation typically contains high diversity of native annual plants relative to shrubs, cacti, perennial herbaceous species, or other plant life forms. This vegetation type is also very susceptible to exotic, invasive annual plants, which promote fire by changing fuel properties. The impact of fire on most perennial species is severe but the impact on native annual plants is not well understood. We measured annual species composition in five sites that each contained paired burned and unburned stands in the western Colorado Desert, California. The burned stands at each site ranged in time since fire from 3 to …

Bottom-Up Effects Of Substrate On Two Adjacent Shrub Communities And The Distribution Of A Rare And Endangered Plant Species, Astragalus Jaegerianus Munz., Barry A. Prigge, Thomas R. Huggins, M R. Sharifi, Philip W. Rundel

Natural Resources and Environmental Issues

Edaphic habitats are botanically interesting because of differences in vegetation with neighboring sites and because they tend to harbor rare species. In the central Mojave Desert, there are granite colluvial substrates where creosote bush, the dominant shrub in the area, is sparser and generally smaller than in the neighboring creosote bush communities. It is on these sites that the Lane Mountain milkvetch, a rare and federally endangered species, is restricted. The milkvetch is a nitrogen-fixer and grows under and within the canopy of host shrubs. Our previous studies have demonstrated that the milkvetch has no preference for species of host …

Seasonal Soil Co2 Flux Under Big Sagebrush (Artemisia Tridentata Nutt.), Michael C. Amacher, Cheryl L. Mackowiak

Natural Resources and Environmental Issues

Soil respiration is a major contributor to atmospheric CO2, but accurate landscape-scale estimates of soil CO2 flux for many ecosystems including shrublands have yet to be established. We began a project to measure, with high spatial and temporal resolution, soil CO2 flux in a stand (11 x 25 m area) of big sagebrush (Artemisia tridentata Nutt.) at the Logan, Utah, Forestry Sciences Laboratory. Beginning on Nov. 1, 2009, hourly soil CO2 flux measurements were made at a single location in the stand using the Li-Cor LI-8100 soil CO2 flux instrument and 20-cm long-term chamber. Beginning in April, 2010, monthly soil …

Trend Of Gardner Saltbush And Halogeton In The Lower Green River Basin, Wyoming, Sherel Goodrich, Aaron Zobell

Natural Resources and Environmental Issues

Displacement of Gardner saltbush (Atriplex gardneri) by halogeton (Halogeton glomeratus) is being recorded at several points in the Lower Green River Basin, Wyoming by line intercept measurements and by repeat photography. This paper gives results of the monitoring studies as of 2009. Total displacement of Gardner saltbush by halogeton has taken as little as 10 years at some locations. Loss of Gardner saltbush to halogeton has major management implications.

3d Mapping Of The Spry2 Domain Of Ryanodine Receptor 1 By Single-Particle Cryo-Em, Alex Peralvaerz-Marin, Hanshen Tae, Phillip G. Board, Marco G. Casarotto, Angela F. Dulhunty, Montserrat Samsó

Physiology and Biophysics Publications and Presentations

The type 1 skeletal muscle ryanodine receptor (RyR1) is principally responsible for Ca2+release from the sarcoplasmic reticulum and for the subsequent muscle contraction. The RyR1 contains three SPRY domains. SPRY domains are generally known to mediate protein-protein interactions, however the location of the three SPRY domains in the 3D structure of the RyR1 is not known. Combining immunolabeling and single-particle cryo-electron microscopy we have mapped the SPRY2 domain (S1085-V1208) in the 3D structure of RyR1 using three different antibodies against the SPRY2 domain. Two obstacles for the image processing procedure; limited amount of data and signal dilution introduced by the …

State-Dependent Camp Binding To Functioning Hcn Channels Studied By Patch-Clamp Fluorometry, Shengjun Wu, Zhanna V. Vysotskaya, Xinping Xu, Changan Xie, Qinglian Liu, Lei Zhou

Physiology and Biophysics Publications and Presentations

Abstract

One major goal of ion channel research is to delineate the molecular events from the detection of the stimuli to the movement of channel gates. For ligand-gated channels, it is challenging to separate ligand binding from channel gating. Here we studied the cyclic adenosine monophosphate (cAMP)-dependent gating in hyperpolarization-activated cAMP-regulated (HCN) channel by simultaneously recording channel opening and ligand binding, using the patch-clamp fluorometry technique with a unique fluorescent cAMP analog that fluoresces strongly in the hydrophobic binding pocket and exerts regulatory effects on HCN channels similar to those imposed by cAMP. Corresponding to voltage-dependent channel activation, we observed …

Respecting Language As Part Of Ethnicity: Title Vii And Language Discrimination At Work, Carlo A. Pedrioli

Faculty Scholarship

This article argues that, in the absence of a legitimate, non-discriminatory reason or a business necessity, Title VII of the 1964 Civil Rights Act can protect employees from language-based discrimination in the workplace. Language is a part of one’s ethnicity, which refers to one’s culture. Ethnicity, much as race already does, should receive protection under Title VII. Plaintiffs, however, have the burden of proof in litigation, and so a plaintiff who sues under a discrimination theory should have to make his or her case to the appropriate fact-finder. Drawing upon the insights of critical theory, particularly to explore concepts like …

Substrate Suppression Of Thermal Roughness In Stacked Supported Bilayers, Laurence Lurio, Justin D. Berry, Curt M. Decaro, Gang Chen, Zhang Jiang, Yikong Ma, Atul N. Parikh, Alec R. Sandy, Sunil Sinha, Lobat Tayebi

Faculty Articles, Papers, and Other Scholarship

We have fabricated a stack of five 1,2-dipalmitoyl-sn-3-phosphatidylethanolamine (DPPE) bilayers supported on a polished silicon substrate in excess water. The density profile of these stacks normal to the substrate was obtained through analysis of x-ray reflectivity. Near the substrate, we find the layer roughness and repeat spacing are both significantly smaller than values found in bulk multilayer systems. The reduced spacing and roughness result from suppression of lateral fluctuations due to the flat substrate boundary. The layer spacing decrease then occurs due to reduced Helfrich repulsion.

Sampling Methods For Acropora Corals, Other Benthic Coral Reef Organisms, And Marine Debris In The Florida Keys: Field Protocol Manual For 2011-2012 Assessments, Steven Miller, Leanne M. Rutten, Mark Chiappone

Marine & Environmental Sciences Faculty Reports

The 2011-2012 sampling of Acropora corals, other coral reef benthic invertebrates, and marine debris in the Florida Keys National Marine Sanctuary (FKNMS) is being undertaken as a spatially intensive effort to provide updated population distribution and abundance information. The particular focus of surveys in the Florida Keys, as well as in the U.S. Caribbean (Puerto Rico and the U.S.V.I.), concerns the habitat distribution, colony density, size, condition, and population abundance of Acropora corals. Surveys in the Florida Keys also include assessments of urchins, mollusks, anemones, corallimorpharians, and marine debris. These additional assessments are relatively fast and easy to perform.

Multicomponent Folate-Targeted Magnetoliposomes: Design, Characterization, And Cellular Uptake, Geoffrey D. Bothun, Alline Lelis, Yanjing Chen, Kyle Scully, Linnea E. Anderson, Matthew A. Stoner

Chemical, Biomolecular, and Materials Engineering Faculty Publications

Folate-targeted cationic magnetoliposomes (FTMLs) have been prepared with coencapsulated doxorubicin (DOX) and anionic superparamagnetic iron oxide (SPIO) nanoparticles (NPs) with 5 nm γ-Fe₂O₃ cores and 16 nm hydrodynamic diameters. NP encapsulation (89%) was confirmed by cryogenic transmission electron microscopy (TEM), and the presence of the oppositely charged NPs did not cause liposome aggregation. The FTMLs had an average diameter of 174 ± 53 nm and existed as unilamellar and cup-shaped liposomes, which was attributed to dissimilar lipid packing parameters and the presence of PEG-lipids. A 3-fold increase in DOX release was achieved over 2 hours when the …

In our book, Patriarchal Religion, Sexuality, and Gender: A Critique of New Natural Law, Nicholas Bamforth and I argue that a group of thinkers, the new natural lawyers—including, prominently, Professors John Finnis and Robert George—are not what they claim to be. The new natural lawyers claim that their views are a secular form of political theory and, as such, are as much entitled to clarify important questions of value in liberal democracies as are any other such secular political theories—say, utilitarianism or contractualism— that try to make sense of the deep values of equality and liberty that justify democracy.
