Temporal Relationships Between Plasma Cortisol, Corticosteroid-Binding Globulin (Cbg), And The Free Cortisol Index (Fci) In Pigs, Rebecca Jackson Adcock
Temporal Relationships Between Plasma Cortisol, Corticosteroid-Binding Globulin (Cbg), And The Free Cortisol Index (Fci) In Pigs, Rebecca Jackson Adcock
Masters Theses
The free fraction of cortisol in circulation is that which is biologically available to cells. In swine, more than 60% of cortisol is bound to its carrier glycoprotein, porcine corticosteroid-binding globulin (pCBG). The Free Cortisol Index (FCI), which is the ratio of total cortisol to CBG concentrations, has been shown in humans to correlate well with free cortisol. In experiment one, the relationship between plasma free cortisol and the free cortisol index (FCI) was evaluated in 8-wk old pigs over a 24 h period and in response to the administration of saline (n = 4) and ACTH (n = 4). …

Interpretive Signs Designed To Trigger Naturalist Intelligence At Two American Zoos, Martha Bryant
Graduate Student Dissertations, Theses, Capstones, and Portfolios
An investigation of interpretive graphics was conducted in 2005 at two mid-sized AZA-accredited zoos, Lowry Park Zoo, Tampa, Florida and Knoxville Zoo, Knoxville, Tennessee. The Lowry Park Zoo study investigated signs at a red-tailed hawk and sandhill crane exhibit. Combination signs and wordless signs were more effective helping visitors see animals, increasing holding time, and number of engagements than treatments of no signs, or signs with words only. A second study, at Knoxde Zoo, tested combination and wordless signs in a children's zoo, investigating 31 signs at a 3.5-acre exhibit. Comparisons of visitors seeing the animals/using interactive exhibit elements, holding …
Re-Integrating Crops And Livestock In Maine: An Economic Analysis Of The Potential For And Profitability Of Integrated Agricultural Production, Aaron K. Hoshide
Re-Integrating Crops And Livestock In Maine: An Economic Analysis Of The Potential For And Profitability Of Integrated Agricultural Production, Aaron K. Hoshide
Electronic Theses and Dissertations
This thesis examines the profitability of and sustainability indicators for potato and dairy farms in Maine integrating crops and livestock in two different ways. The first is inter-farm coupling, where two or more specialized producers are close enough to exchange manure applications for crops used as livestock feed. Land base is shared between farmers. The second is where farms are on-farm integrated. Here crops and livestock are raised on the same farm and manure is applied to cash crops and livestock feed crops. Face-to-face interviews with Maine producers were used to construct integrated and non-integrated representative budgets. Assuming …

The objectives of this experiment were: 1) to validate endophyte status of the experimental pasture through determining ergovaline levels of masticate samples and animal response using serum prolactin concentrations, weight gain, and rectal temperatures, 2) to compare weight and composition of rumen contents of cannulated …
Implications Of Spatial Autocorrelation And Dispersal For The Modeling Of Species Distributions, Volker Bahn
Implications Of Spatial Autocorrelation And Dispersal For The Modeling Of Species Distributions, Volker Bahn
Electronic Theses and Dissertations
Modeling the geographical distributions of wildlife species is important for ecology and conservation biology. Spatial autocorrelation in species distributions poses a problem for distribution modeling because it invalidates the assumption of independence among sample locations. I explored the prevalence and causes of spatial autocorrelation in data from the Breeding Bird Survey, covering the conterminous United States, using Regression Trees, Conditional Autoregressive Regressions (CAR), and the partitioning of variance. I also constructed a simulation model to investigate dispersal as a process contributing to spatial autocorrelation, and attempted to verify the connection between dispersal and spatial autocorrelation in species' distributions in empirical …
Microbial And Chemical Affects On Leachate From Calcareous Soils Treated With Wastewater Effluent, Craig M. Paul
Microbial And Chemical Affects On Leachate From Calcareous Soils Treated With Wastewater Effluent, Craig M. Paul
Theses and Dissertations
Increasing human populations are placing greater strain on water resources, prompting the use of treated wastewater effluent for irrigation in some areas, including the desert regions of the Western United States. To determine the potential effects of using secondary effluent for irrigation, we applied wastewater effluent and irrigation waters to natural and artificially constructed calcareous soils in greenhouse and field lysimeters, and in soil columns. The leachate from one field lysimeter contained increased fecal coliform counts than the effluent. Leachate coliform counts were decreased or not significantly changed in two field lysimeters. Electrical conductivity (EC), sodium adsorption ratio (SAR), chloride …
Investigation Of The Toxic Affect Of Manganese On Ruminal Microbial Digestion And Growth, Erin Dearing
Investigation Of The Toxic Affect Of Manganese On Ruminal Microbial Digestion And Growth, Erin Dearing
Undergraduate Honors Capstone Projects
This research investigated the toxic effect of manganese, in a reduced chemical state, on rumen microbial metabolism and growth. The reduced form of manganese is the soluble state found in subsurface waters and has a high red-ox potential. In the study, we investigated the effects of reduced manganese at varying concentrations, on rumen microbial ability to replicate and metabolize carbohydrates. The hypotheses that we tested were as follows: (1) reduced manganese decreases the rate of pH drop associated with rumen culture fermentation of a com based diet and (2) reduced manganese decreases the bacterial growth in rumen culture, as measured …

Wildlife-Vehicle Collisions In Utah: An Analysis Of Wildlife Road Mortality Hotspots, Economic Impacts And Implications For Mitigation And Management, Christine A. Kassar
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
In the US, the roaded landscape has had serious ecological effects. We studied wildlife-vehicle collisions occurring on the 248 state routes in Utah from 1992 to 2002. We tracked trends and patterns in deer-vehicle collisions, evaluated all routes for frequency of deer kills, and identified "hotspots" (segments of road with high concentrations of collisions per mile). We found pronounced patterns: e.g., 61.15% of all collisions occurred on only 10 routes. We studied the effects of posted speed limit and annual average daily traffic flow and found that no relationship existed between traffic volume and/or posted speed limit and the number …

Observed Omnivory In The Herbivorous Blue Tilapia (Oreochromis Aureus), Stephen M. Oliveira Jr.
UNLV Theses, Dissertations, Professional Papers, and Capstones
Gila seminuda, a native endangered species, and Oreochromis aureus, a nonnative invasive species, share the same habitat in the form of the Reid Gardner Power Plant intake ponds. The purpose of this study is to characterize the feeding habits of Oreochromis aureus within the Reid Gardner Power Plant intake ponds and address the potential predation habits of Oreochromis aureus. Stomach contents of O. aureus were identified and analyzed using chi-square and log-likelihood ratio techniques, with respect to mass, length, girth, gender, or spatial distribution of samples. Results showed omnivorous behavior with a 7.00% predatory/prey relationship, and no difference of feeding …
Bird And Small Mammal Communities Of Sagebrush-Dominated Mountain Meadows: An Examination Of Meadow Characteristics As Part Of A Hierarchical, Multi-Level Study Of The Wasatch-Cache National Forest, Elizabeth Johnson
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Sagebrush shrubsteppe ecosystems have increasingly garnered attention as an endangered ecosystem. Ninety nine percent of all sagebrush ecosystems are thought to have been impacted by humans, and over 50% of grassland and shrubsteppe species are believed to be in decline. Most of the research on sagebrush ecosystems has been conducted at lower elevations and in large expanses of sagebrush. A considerable amount of sagebrush is found at higher elevations, often in meadows found within a forest matrix. The role of this high-elevation habitat is poorly understood. We conducted bird, small mammal, vegetation, and soil surveys in sagebrush-dominated mountain meadows within …

Dissertations
Resource equalization represents the historical and theoretical basis for American school finance and its ideals continue to dominate discussion and practice. During the last decade and a half, the national aspiration for equitable distribution of school finance resources has started a transformation into a derivative notion of adequacy. This equity policy derivative embraces the idea of sufficiency, which in turn implies a standard. The concept of educational adequacy has grown to mean the achievement of high absolute standards. Equity (equalization) theorists measure resource level on a relative basis; each student relative to all others. Adequacy adherents measure student achievement against …
The Defensin Gene In Dermacentor Variabilis And Ixodes Scapularis, Katherine Corbett Seguin
The Defensin Gene In Dermacentor Variabilis And Ixodes Scapularis, Katherine Corbett Seguin
Biological Sciences Theses & Dissertations
In response to microbial challenge, invertebrates rely on their innate immune response to recognize and destroy harmful pathogens. One of the primary proteins produced by the response and that has been observed in many invertebrates, including insects, mussels, and ticks, is defensin. These proteins are responsible for forming pores in the membranes of invading microbes thereby destroying them. This study examined the gene coding region for defensin in two important tick disease vectors, Dermacentor variabilis and Ixodes scapularis. PCR amplification of the genes from tick chromosomal DNA resulted in the amplification of a 225 base pair amplicon. Sequencing of …
Calorespirometric Evidence For Adaptation Of Blackbrush And Shadscale To Growth Season Temperatures In Cold Deserts, Heidi A. Summers
Calorespirometric Evidence For Adaptation Of Blackbrush And Shadscale To Growth Season Temperatures In Cold Deserts, Heidi A. Summers
Theses and Dissertations
Coleogyne ramosissima Torr. (blackbrush) and Atriplex confertifolia [Torr. & Frem.] Wats. (shadscale) are cold desert shrubs from different families that often grow together in the Great Basin and the Colorado Plateau in the life zone between 800 and 2000 m elevation. Tissue and seeds from the two species were collected from several localities. Metabolic heat and carbon dioxide production rates were measured with calorespirometry on tissue from field-grown plants and on seedlings at temperatures from 5 to 35°C at 5°C intervals. Blackbrush adapts to higher temperatures earlier than does shadscale, and once it has adjusted to higher temperatures, anabolic rates …

Theses, Dissertations and Capstones
A study was undertaken to classify eight stream reaches in the North Branch of the Potomac River watershed and determine if geomorphologic differences influenced the availability of fish habitat structure and fish density. Stream reaches were classified using Rosgen Level II (1996) methods, and fish habitat was determined using Hydraulic Channel Unit (HCU) classification based on a method modified from Bisson et al. (1982). Other habitat variables were also studied such as stream shading and physical habitat based on the Rapid Bioassessment Protocol (Barbour et al. 1999). Despite the differences in HCU density between sites, HCU density did not influence …
Natural History And Conservation Biology Of A Southern West Virginia Contour Surface Mine Reptile And Amphibian Community, Zachary James Loughman
Natural History And Conservation Biology Of A Southern West Virginia Contour Surface Mine Reptile And Amphibian Community, Zachary James Loughman
Theses, Dissertations and Capstones
During the 2004-2005 field seasons, natural history of a herpetofaunal community was studied on an abandoned contour surface mine in Eccles, Raleigh County, West Virginia. This study is the first natural history investigation of amphibian and reptile populations present on an abandoned mine site. Specific natural history parameters for each order on the mine were investigated to determine what effect the post mining landscape had on herpetofaunal communities. Pond breeding caudates population success was dependent on life history parameters. Anurans were efficient at re-colonization, with 12 of a possible 14 species collected on the mine site. Anuran diversity was linked …
Comparisons Of Morphology And Reproductive Status Of Plethodon Glutinosus At High, Middle, And Low Elevations In West Virginia, Cynthia F. Lucas
Comparisons Of Morphology And Reproductive Status Of Plethodon Glutinosus At High, Middle, And Low Elevations In West Virginia, Cynthia F. Lucas
Theses, Dissertations and Capstones
Plethodon glutinosus populations in West Virginia were looked at in three different elevations. Objectives were to determine if there is enough difference in elevation to cause different populations to vary in morphology and reproduction. Nine morphological measurements were taken to represent both size and proportional shape. Sexual dimorphism was found in all measurements only in low elevations, males being larger (p<0.001-p=0.041). Mean measurements between the three elevations showed significant differences (p<0.005) in all measurements excluding head width, tail length, and 3rd digit length. Salamanders were dissected; testes and vasa deferentia were removed from males and ovaries with follicles were removed from females. Results showed males in lower and middle elevations deposit spermatophores May-July. Low sample sizes in higher elevations provided inconclusive results. Females of lower elevations lay eggs early-mid summer. Middle and higher elevations results revealed a likely spring oviposition, or possibly a fall oviposition.
Analysis Of Genotypic And Phenotypic Differences In Desmognathus Quadramaculatus Across The Southern Appalachians, Deborah Susan Merritt
Analysis Of Genotypic And Phenotypic Differences In Desmognathus Quadramaculatus Across The Southern Appalachians, Deborah Susan Merritt
Theses, Dissertations and Capstones
Populations of Desmognathus quadramaculatus were compared for genotypic and phenotypic differences across 5 states in the Southern Appalachians. Series consisting of 10 salamanders each were collected from West Virginia, Virginia, Tennessee, North Carolina and Georgia. Salamanders were assessed for genotypic differences by using allozyme (proteins with polymorphic loci) electrophoresis staining for 13 loci of the muscle, liver and stomach tissue. Nei’s genetic distance was used to score genetic variation between populations. Phenotypic differences were assessed by comparing 10 external morphological measurements between populations. Mahalanobis’ distance was used to score morphological differences between populations. Both genetic and morphological differences were correlated …

Theses, Dissertations and Capstones
There are over 4000 documented caves in West Virginia, potentially providing refuge and habitat for a diversity of amphibians and reptiles. Spring Salamanders, Gyrinophilus porphyriticus, are among the most frequently encountered amphibians in caves. Surveys of 25 caves provided expanded distribution records and insight into ecology and diet of G. porphyriticus. Over 500 species locality records were compiled in a nearly comprehensive list. The Gyrinophilus population from General Davis Cave is of particular interest. In 1977, Besharse and Holsinger first described the West Virginia Spring Salamander, G. subterraneus; however, its taxonomic status is unclear. In order to …

Regulation Of Glucose Metabolism In Dairy Cattle, Christie Cheatham Stanley
Regulation Of Glucose Metabolism In Dairy Cattle, Christie Cheatham Stanley
LSU Doctoral Dissertations
The experiments described herein are designed to elucidate many metabolic changes that occur to regulate the partitioning of nutrients between production and animal maintenance with particular regard to glucose metabolism and insulin sensitivity. The onset of milk production and parturition causes dramatic stress to the cow. The challenge of improving metabolism during this period is being addressed by nutritional management with the possibility of the addition of supplements. The use of Ca-propionate as a supplement did not affect glucose metabolism in transition cows. The data revealed that insulin sensitivity was low during the transition period, but the tissue responses to …
