The Effects Of Resource Availability On Alternative Mating Tactics In Guppies (Poecilia Reticulata), Gita R. Kolluru, Gregory F. Grether

Biological Sciences

Food availability can influence the optimal allocation of time and energy among alternative behaviors such as foraging, courting, and competing for mates. If populations differ consistently in food availability, selection may cause geographic divergence in allocation strategies. At the opposite extreme, a norm of reaction may evolve such that food intake influences the allocation strategy of individuals in the same way in all populations. Between these two extremes, food intake reaction norms may diverge genetically among populations. For example, at sites where food is scarce, selection may strengthen the effect of food intake on behavior, whereas at sites with abundant …

The Large Genome Constraint Hypothesis: Evolution, Ecology And Phenotype, Charles A. Knight, Nicole A. Molinari, Dmitri A. Petrov

Biological Sciences

• Background and Aims If large genomes are truly saturated with unnecessary ‘junk’ DNA, it would seem natural that there would be costs associated with accumulation and replication of this excess DNA. Here we examine the available evidence to support this hypothesis, which we term the ‘large genome constraint’. We examine the large genome constraint at three scales: evolution, ecology, and the plant phenotype.

• Scope In evolution, we tested the hypothesis that plant lineages with large genomes are diversifying more slowly. We found that genera with large genomes are less likely to be highly specious – suggesting a large …

Range Wars: The Plains Frontier Of Boys Don't Cry, Christina E. Dando

Geography and Geology Faculty Publications

In the mythology of the American West, range wars pitted ranchers against farmers, insiders versus outsiders, each struggling to control access to land, each fighting to preserve the freedom and opportunities that first drew them to the frontier. The film, Boys Don't Cry (2000), set on the contemporary Plains and based on actual events, tells of insiders and outsiders who attempt to claim a place. The individuals at the center of the film challenge symbolic fences and attempt border-crossings as they struggle to construct and live with their identities. Plains citizens are depicted to erect and police societal fences, defining …

Does Intracellular Metabolite Diffusion Limit Post-Contractile Recovery In Burst Locomotor Muscle?, Stephen T. Kinsey, Pragyansri Pathi, Kristin M. Hardy, Amanda Jordan, Bruce R. Locke

Biological Sciences

Post-metamorphic growth in the blue crab entails an increase in body mass that spans several orders of magnitude. The muscles that power burst swimming in these animals grow hypertrophically, such that small crabs have fiber diameters that are typical of most cells (600μm). Thus, as the animals grow, their muscle fibers cross and greatly exceed the surface area to volume ratio (SA:V) and intracellular diffusion distance threshold that is adhered to by most cells. Large fiber size should not impact burst contractile function, but post-contractile recovery may be limited by low SA:V and excessive intracellular diffusion distances. A number of …

Utah Wolf Management Plan, Utah Division Of Wildlife Resources Publication #: 05-17, The Utah Division Of Wildlife Resources, The Utah Wolf Working Group

All U.S. Government Documents (Utah Regional Depository)

This plan will guide management of wolves in Utah during an interim period from delisting until 2015, or until it is determined that wolves have established1 in Utah, or assumptions of the plan (political, social, biological, or legal) change. During this interim period, arriving wolves will be studied to determine where they are most likely to settle without conflict.

The goal of this plan is to manage, study, and conserve wolves moving into Utah while avoiding conflicts with the wildlife management objectives of the Ute Indian Tribe; preventing livestock depredation; and protecting the investment made in wildlife in Utah.

Big Sagebrush Response To One-Way And Two-Way Chaining In Southeastern Utah, John A. Fairchild, James N. Davis, Jack D. Brotherson, Usda Forest Service

All U.S. Government Documents (Utah Regional Depository)

A decadent, mixed stand of Wyoming big sagebrush, Artemisia tridentata wyomingensis, and mountain big sagebrush, Artemisia tridentata vaseyana, located north of Cisco, Utah, was subjected to one-way and two-way chaining treatments in November 1987. The effect of the treatments on plant community characteristics and shrub vigor was documented over a 3-year period. Stand density was reduced 60 percent on sites chained two ways and 43 percent on sites chained over once. Shrubs on one-way chained sites produced more leader growth in 1989 and 1990 than those on untreated sites or sites chained two ways. Browse production on one-way chained sites …

Cooperation And Coordination Are Invasive Species: Important For Effective Management Of Invasive Weeds, U.S. Government Accountability Office

All U.S. Government Documents (Utah Regional Depository)

Invasive weeds, native or nonnative plant species, cause harm to natural areas such as rangelands or wildlife habitat and economic impacts due to lost productivity of these areas. While the federal investment in combating invasive species is substantial most has been concentrated on agricultural lands, not on natural areas. In this report, GAO describes (1) the entities that address invasive weeds in natural areas and the funding sources they use; (2) federal, state, and local weed management officials’ views on the barriers to weed management; and (3) their opinions about how additional resources for weed management could be distributed. GAO …

Profiling Condition-Specific, Genome-Wide Regulation Of Mrna Stability In Yeast, Wendy Olivas, B. Foat, S. Houshmandi, H. Bussemaker

Biology Department Faculty Works

The steady-state abundance of an mRNA is determined by the balance between transcription and decay. Although regulation of transcription has been well studied both experimentally and computationally, regulation of transcript stability has received little attention. We developed an algorithm, MatrixREDUCE, that discovers the position-specific affinity matrices for unknown RNA-binding factors and infers their condition-specific activities, using only genomic sequence data and steady-state mRNA expression data as input. We identified and computationally characterized the binding sites for six mRNA stability regulators in Saccharomyces cerevisiae, which include two members of the Pumilio-homology domain (Puf) family of RNA-binding proteins, Puf3p and Puf4p. We …

Yeast Puf3 Mutants Reveal The Complexity Of Puf-Rna Binding And Identify A Loop Required For Regulation Of Mrna Decay, Wendy Olivas, S. Houshmandi

Biology Department Faculty Works

The eukaryotic Puf proteins regulate mRNA translation and degradation by binding the 3' untranslated regions of target mRNAs. Crystal structure analysis of a human Puf bound to RNA suggested a modular mode of binding, with specific amino acids within each of eight repeat domains contacting a single nucleotide of the target RNA. Here we study the mechanism by which the yeast Puf3p binds and stimulates the degradation of COX17 mRNA. Mutation of the predicted RNA-binding positions of Puf3p to those found in Puf5p demonstrated that a single amino acid change in Puf3p abolished detectable binding to COX17. Since this amino …

The Plant Ontology Consortium (POC) (www.plantontology.org) is a collaborative effort among several plant databases and experts in plant systematics, botany and genomics. A primary goal of the POC is to develop simple yet robust and extensible controlled vocabularies that accurately reflect the biology of plant structures and developmental stages. These provide a network of vocabularies linked by relationships (ontology) to facilitate queries that cut across datasets within a database or between multiple databases. The current version of the ontology integrates diverse vocabularies used to describe Arabidopsis, maize and rice (Oryza sp.) anatomy, morphology and growth stages. Using the ontology browser, …

Nuclear Chemistry Unit Designed For Ames Community School District Chemistry Classes, Alan John Junck

Graduate Research Papers

Nuclear chemistry is a topic that is relevant to all areas of science, but often left out of the curriculum due to a lack of time or the belief by teachers that it can be covered in someone elses course. If we are to help students become scientifically literate, the basic science of nuclear chemistry and its numerous applications must be addressed at some point in the curriculum. An important part of the local history of Ames is its involvement in the Manhattan Project by the Department of Energy Ames Lab. By creating a unit that deals with some of …

Tgf-Beta1 And Serum Both Stimulate Contraction But Differentially Affect Apoptosis In 3d Collagen Gels, Tetsu Kobayashi, Xiangde Liu, Hui Jung Kim, Tadashi Kohyama, Fu-Qiang Wen, Shinji Abe, Qiuhong Fang, Yun Kui Zhu, John R. Spurzem, Peter Bitterman, Stephen I. Rennard

Journal Articles: Pulmonary & Critical Care Med

Apoptosis of fibroblasts may be key for the removal of cells following repair processes. Contraction of three-dimensional collagen gels is a model of wound healing and remodeling. Here two potent inducers of contraction, TGF-beta1 and fetal calf serum (FCS) were evaluated for their effect on fibroblast apoptosis in contracting collagen gels. Human fetal lung fibroblasts were cultured in floating type I collagen gels, exposed to TGF-beta1 or FCS, and allowed to contract for 5 days. Apoptosis was evaluated using TUNEL and confirmed by DNA content profiling. Both TGF-beta1 and serum significantly augmented collagen gel contraction. TGF-beta1 also increased apoptosis assessed …

Electromyographic (Emg) Analysis Of Trunk Muscles At The Point Of Puck Contact During Slap And Wrist Shots Of Female Ice Hockey Athletes, Lon Donald, Kristi Kjellgren, Jodi Young, Michael Young

Physical Therapy Scholarly Projects

The number of female hockey players has increased significantly in the last decade. The first recorded female hockey game was in Ottawa in 1889. Since that time, hockey has spread into the United States .. Today, USA Hockey, Inc. reports 40,000 registered females and the Canadian Hockey Association has 55,000 female hockey players. Despite the rising popularity of the sport among females, there is little research specifically related to female hockey players.

Golf, tennis, and hockey swings utilize similar rotational components about the trunk. Trunk rotation is controlled and produced by the erector spinae, external oblique and rectus abdominus muscles. …

Assessment And Prediction Of Self-Reported Hiv-Risk Behaviors By Women In Substance Abuse Treatment, Radhika Sehgal

Master's Theses and Doctoral Dissertations

This study compared information obtained from self-administered questionnaires (SAQ) and faceto- face interview (FTFI) versions of the HIV Risk-taking Behavior Scale. This study also compared women intravenous drug users (IVDU’s) and non-IVDU’s on rates of HIV risk behaviors and the extent to which unstable housing, unemployment, single parenthood, barriers to accessing health care, and number of years of drug abuse predicted HIV risk. There were no differences in rates of risk behavior reported between SAQ and FTFI formats. IVDU’s had higher sexual risk behaviors than non-IVDU’s. Unstable housing significantly predicted risk behavior. Relative to those with more education, those with …

The Effects Of Childhood Obesity On Self-Esteem, Heather L. Paxton

Theses, Dissertations and Capstones

Obesity is a growing health problem affecting children in the United States. The prevalence of obesity has increased dramatically over the past 10 years across virtually all populations and age groups. Recent data suggest that 15 percent of U.S. children are severely overweight or obese (National Center for Health Statistics, 2002) . Obese children are at risk for significant health problems, but also face many psychological and social consequences, including low self-esteem. Children who are obese face an increased risk of emotional problems lasting well into adulthood. Factors such as peer rejection, weight-related teasing, and internalized social standards play a …
