Tactics And Economics Of Wildlife Oral Rabies Vaccination, Canada And The United States, Ray T. Sterner, Martin I. Meltzer, Stephanie A. Shwiff, Dennis Slate Aug 2009

Tactics And Economics Of Wildlife Oral Rabies Vaccination, Canada And The United States, Ray T. Sterner, Martin I. Meltzer, Stephanie A. Shwiff, Dennis Slate

United States Department of Agriculture Wildlife Services: Staff Publications

Progressive elimination of rabies in wildlife has been a general strategy in Canada and the United States; common campaign tactics are trap–vaccinate–release (TVR), point infection control (PIC), and oral rabies vaccination (ORV). TVR and PIC are labor intensive and the most expensive tactics per unit area (≈$616/km2 [in 2008 Can$, converted from the reported $450/km2 in 1991 Can$] and ≈$612/km2 [$500/km2 in 1999 Can$], respectively), but these tactics have proven crucial to elimination of raccoon rabies in Canada and to maintenance of ORV zones for preventing the spread of raccoon rabies in the United States.

Effects Of Nitrogen Supply On The Root Morphology Of Corn And Velvetleaf, Kimberly D. Bonifas, John L. Lindquist Aug 2009

Effects Of Nitrogen Supply On The Root Morphology Of Corn And Velvetleaf, Kimberly D. Bonifas, John L. Lindquist

Department of Agronomy and Horticulture: Faculty Publications

Root morphology will affect interplant competition for soil nutrients. Research was conducted to assess fine root fraction, mean root radius, specific root length, root length density, and nitrogen (N) uptake per unit fine root biomass of corn and velvetleaf over time and in response to nitrogen supply. Pots containing either corn or velvetleaf were embedded in the ground and received one of three N treatments. Plants were destructively sampled on 10 dates during each of two years and root subsamples analyzed using root scanning software. While corn root morphology was more responsive to N supply than velvetleaf, velvetleaf N uptake …

Evolutionary And Functional Insights Into The Mechanism Underlying High-Altitude Adaptation Of Deer Mouse Hemoglobin, Jay F. Storz, Amy M. Runck, Stephen J. Sabatino, John K. Kelly, Nuno Ferrand, Hideaki Moriyama, Roy E. Weber, Angela Fago

Jay F. Storz Publications

Adaptive modifications of heteromeric proteins may involve genetically based changes in single subunit polypeptides or parallel changes in multiple genes that encode distinct, interacting subunits. Here we investigate these possibilities by conducting a combined evolutionary and functional analysis of duplicated globin genes in natural populations of deer mice (Peromyscus maniculatus) that are adapted to different elevational zones. A multilocus analysis of nucleotide polymorphism and linkage disequilibrium revealed that high-altitude adaptation of deer mouse hemoglobin involves parallel functional differentiation at multiple unlinked gene duplicates: two α-globin paralogs on chromosome 8 and two β-globin paralogs on chromosome 1. Differences in …

A Nebraska Bird-Finding Guide, Paul A. Johnsgard Aug 2009

A Nebraska Bird-Finding Guide, Paul A. Johnsgard

Papers in Ornithology

Persons living in Nebraska often feel that they are living in a cultural wasteland; its citizenry preoccupied with violent sports such as hunting and football. Yet many are unaware that they are actually residing in one of the prime locations in the entire world for observing and enjoying some of the most aesthetically appealing of all the world's biological attractions. The area around Kingsley Dam and Lake McConaughy, for example, is known to have attracted more than 330 bird species, including 104 breeders (plus 17 probable breeders) making it the third-most species-rich bird location in the interior U.S.A. (after Laguna …

Determination Of 3-Dimensional Deformations Of The Alveolar Sac During Simulated Breathing, Joseph M. Ferrara Aug 2009

Determination Of 3-Dimensional Deformations Of The Alveolar Sac During Simulated Breathing, Joseph M. Ferrara

Theses

Mechanical properties of the parenchyma of the lung are currently unknown and difficult to quantify. Creating a computer model with valid property values will allow researchers to further investigate particle mixing in the lung during inhalation and exhalation. One challenge with modeling the material of the lung is the intricate geometry of the alveolar sac. Researchers are currently trying to model particle deposition within the lung using computational fluid dynamics. However, the mechanical properties of alveolar sac structure are currently undetermined. Due to the complexity of the physical structure of an alveolar sac, it has been a challenge to model …

Fecal-Sac Ingestion By Spotted Towhees, Jenny E. Mckay, Michael T. Murphy, Sarah Bartos Smith, Jennifer K. Richardson Aug 2009

Fecal-Sac Ingestion By Spotted Towhees, Jenny E. Mckay, Michael T. Murphy, Sarah Bartos Smith, Jennifer K. Richardson

Biology Faculty Publications and Presentations

Altricial nestlings encase excrement in fecal sacs that parents remove by either ingesting them or transporting them away from the nest. Ingestion may allow energetically or nutritionally deprived parents to recapture energy or nutrients that might be lost because of nestlings' inefficient digestion (the "parental-nutrition hypothesis"), but ingestion may also permit parents to avoid flights from the nest that interfere with parental care (e.g., brooding young; the "economic-disposal hypothesis"). We used a hypothetico-deductive approach to test the two hypotheses' ability to account for fecal-sac ingestion by the Spotted Towhee (Pipilo maculatus). We confirmed the parental-nutrition hypothesis' predictions that …

Business, Science And Ethics: A Case Study In The Necessary Evolution Of Methodology, Thomas I. White Aug 2009

Business, Science And Ethics: A Case Study In The Necessary Evolution Of Methodology, Thomas I. White

Between the Species

Alasdair MacIntyre and David DeGrazia have explored the question of how sophisticated dolphins’ cognitive abilities are, and these thinkers have taken positions based on a flawed methodology that either assert or imply that dolphins fall below humans when it comes to cognitive sophistication and moral consideration. Timothy Fort uses MacIntyre’s characterization of dolphins in his discussion of the value of biology to business ethics. He thereby makes inaccurate and unsupportable claims, and perpetuates a stereotype about dolphins grounded in unintentional speciesism—a stereotype that makes certain unethical treatment of dolphins appear defensible. There is currently little discussion about the appropriate methodology …

The Relationship Between Darkness Of Skin Tone And Mediators Of Elevated Blood Pressure, Brandy Trevino Aug 2009

The Relationship Between Darkness Of Skin Tone And Mediators Of Elevated Blood Pressure, Brandy Trevino

Theses and Dissertations - UTB/UTPA

Numerous studies have found that blood pressure is higher in persons with darker skin tone but the reasons for this remain unclear. This study attempted to investigate this relationship in Hispanics. If such a relationship was found, then it will be addressed whether or not one or more mediators, e.g., hostility, locus of control and perceived racial discrimination mediated the relationship. No such relationship between darkness of skin tone and blood pressure was found. However, statistically significant positive relationships between perceived racial discrimination, locus of control, and hostility were revealed. Discussion of these results focused on the plausible explanation of …

Predicting Leptodactylus (Amphibia, Anura, Leptodactylidae) Distributions: Broad-Ranging Versus Patchily Distributed Species Using A Presence-Only Environmental Niche Modeling Technique, Miguel Fernández, Daniel Cole, W. R. Heyer, Stephen Reichle, Rafael O. De Sá Aug 2009

Predicting Leptodactylus (Amphibia, Anura, Leptodactylidae) Distributions: Broad-Ranging Versus Patchily Distributed Species Using A Presence-Only Environmental Niche Modeling Technique, Miguel Fernández, Daniel Cole, W. R. Heyer, Stephen Reichle, Rafael O. De Sá

Biology Faculty Publications

Locality data available for many, if not most, species of Neotropical frogs are based on written descriptions of the collecting sites, not on GPS device determined coordinate data. The pre-GPS device data are imprecise relative to GPS data. Niche modeling is a powerful technique for predicting geographic distributions that provides the best results when the locality data are precise. The purpose of this study is to determine whether imprecise historical locality data are sufficient such that niche modeling techniques can yield realistic new insights to species-level distributions. Two sets of frogs of the genus Leptodactylus that have known different kinds …

Effects Of Vegetation Structure On Fire Behavior And Wiregrass Seedling Establishment In Xeric Sandhills, Evelyn Wenk Aug 2009

Effects Of Vegetation Structure On Fire Behavior And Wiregrass Seedling Establishment In Xeric Sandhills, Evelyn Wenk

All Theses

The xeric sandhills on Carolina Sandhills National Wildlife Refuge have a monospecific overstory of longleaf pine and an understory dominated by turkey oak and wiregrass. The understory vegetation is spatially heterogeneous within stands, with small patches dominated by either turkey oak or wiregrass, or lacking understory vegetation. I described the fuel complexes created by the variable vegetation structure, in terms of their chemical and physical properties, and used prescribed fire to test for differences in fire behavior among the vegetation types. In addition, I compared the effects of the vegetation structure and below-ground competition on the establishment of wiregrass.

Nudibranchs Of The Ross Sea, Antarctica: Phylogeny, Diversity, And Divergence, Christopher Shields Aug 2009

Nudibranchs Of The Ross Sea, Antarctica: Phylogeny, Diversity, And Divergence, Christopher Shields

All Theses

The Southern Ocean (SO) surrounding Antarctica is extremely cold and geographically isolated. The phylogenetic affinities of only a few SO taxa have been examined in detail; in these, a high degree of endemism and radiation within the SO has been established using molecular phylogenetic methods. In order to address these Antarctic paradigms, we used Bayesian inference to construct phylogenetic trees of nudibranch molluscs based on mitochondrial cytochrome-c oxidase I (COI) and 18S ribosomal DNA. We gathered sequences from temperate (COI n=37; 18S n=31) and polar (COI n=21; 18S n=22) species and then combined them with sequences retrieved from GenBank (COI …

Operation Assessment Of Reservoirs In The Savannah River Basin, Travis Yates Aug 2009

Operation Assessment Of Reservoirs In The Savannah River Basin, Travis Yates

All Theses

Hydropower is generated from three reservoirs in the United States Army Corps of Engineer's Savannah District. These reservoirs include J. Strom Thurmond, Richard B. Russell, and Hartwell. Currently, a contract in place specifies that certain amount of energy must be provided to the region. The contract for the hydropower was based upon the critical hydrologic year of 1981. Historically, this was the most severe drought on record and assumed to provide the lowest net inflows for the three reservoirs, thus providing an attainable or reliable energy amount for the system, which suggests a dependable energy yield.
Reevaluating the contract amount …

Ripe For Change: Roles Of Planners And Landscape Architects At The Interface Of The Land And The Network In An Alternative Agriculture Model For Upstate South Carolina, Jennifer Johnson

All Theses

Both historically and in select areas today, local food systems are the main food supply for communities. Despite the fact that they are not a main source of food for most Americans, since the 1970s there has been a resurgence of U.S. local food systems (Qazi & Selfa, p.161). The movements exist in places where high-profile and vocal personalities (restaurateur, Alice Waters; author, Michael Pollan; or activist Carlo Petrini) also reside. This thesis examines whether the viability of the resurgence in local food systems depends on the commitment of a single person, and if not, whether those who affect the …

Optimization Models For Designing Spatially Compact Ecological Reserve Systems, Lakmali Weerasena Aug 2009

Optimization Models For Designing Spatially Compact Ecological Reserve Systems, Lakmali Weerasena

All Theses

Over the past decades, a number of mathematical models and solution techniques have been developed to preserve reserve sites for species and their natural habitats. Two optimization models for designing spatially compact ecological reserve systems are addressed here as zero-one integer programming problems. These formulations have a bicriteria objective function that is a combination of both boundary length and distance. The two formulations cluster the sites into a relatively small number of compact groups while preserving a required number of sites that contain a certain species using a given amount of resources. Two general types of approaches have been developed …

Synthesis Of Polymers Featuring Novel Diphosphines, Eleanor Tennyson Aug 2009

Synthesis Of Polymers Featuring Novel Diphosphines, Eleanor Tennyson

All Theses

This report details the synthesis of functionalized platinum-based metallopolymers featuring m-terphenyl-scaffolded and light-harvesting phosphine ligands. Substituents placed on both the phosphine and pendant alkynyl units can enhance the optical activity of the metallopolymers depending on their inherent properties. The presence of the platinum metal atom can be exploited to increase conductivity of the molecule and promises to be a unique and valuable modification for polymers to be used in light emitting diodes and photovoltaics. Light-harvesting phosphines prepared in the course of the metallopolymer development have also been used to prepare luminescent polyelectrolytes that prove valuable for well-defined composite film formation …
