Determining The Source Of Individuals: Multilocus Genotyping In Nonequilibrium Population Genetics, Neil Davies, Francis X. Villablanca, George K. Roderick Jan 1999

Determining The Source Of Individuals: Multilocus Genotyping In Nonequilibrium Population Genetics, Neil Davies, Francis X. Villablanca, George K. Roderick

Biological Sciences

Recently founded populations represent an enormous challenge for genetic analysis: new populations are often genetically impoverished, making it hard to find sufficiently variable markers, and what little variation is present tends to be ancestral, rendering phylogenetic methods inappropriate. Recently, novel genetic markers and new statistical analyses have made multilocus genotyping an invaluable tool in the fledgling field of nonequilibrium population genetics. Such advances are not of mere academic interest but address questions of great economic, medical and conservation significance.

Intergenerational Studies In Higher Education: An Initial Survey (1999), Sally Newman, Anita Johnson Jan 1999

Intergenerational Studies In Higher Education: An Initial Survey (1999), Sally Newman, Anita Johnson

Intergenerational

During the last decade, intergenerational studies has begun to attract an increasing number of academics in a variety of academic fields. Similarly, students in increasing numbers are contacting departments in higher education, including intergenerational units such as Generations Together to inquire about courses and training opportunities. Additionally, human service professionals are demonstrating interest in acquiring the knowledge and competencies necessary to effectively administer intergenerational programs as well as earn academic credit for these new professional skills. Evidence of their interest is the number of online inquiries regarding intergenerational training and educational opportunities.

A Case For Site Acclimation In The Reintroduction Of The Endangered Razorback Sucker (Xyrauchen Texanus), United States Geological Survey Jan 1999

A Case For Site Acclimation In The Reintroduction Of The Endangered Razorback Sucker (Xyrauchen Texanus), United States Geological Survey

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

Two site-acclimation studies (Mueller and Marsh 1998, Foster and Mueller 1999) were conducted in 1997 and 1998. The primary emphasis was habitat use and dispersal but we also examined if the rapid dispersal, typically associated with hatchery-produced razorback suckers (suckers), could be mitigated by allowing fish a period of time to recover from stocking-induced stress. Findings of those studies and existing physiological literature suggest that current stocking protocols may subject stocked fish to unnecessary behavioral or physiological stress that could impact performance and ultimately survival. This report presents those findings and recommends an evaluation of existing stocking procedures for the …

Description Of The Pelagic Zooplankton And Fish Communities Of Lakes Powell And Mead, United States Geological Survey Jan 1999

Description Of The Pelagic Zooplankton And Fish Communities Of Lakes Powell And Mead, United States Geological Survey

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

Fishery biologists from Arizona, Nevada, and Utah have been faced with the imposing dilemma of monitoring the pelagic fishery of Lakes Powell and Mead. Standard sampling procedures typically used to monitor shoreline fisheries are simply inadequate for the deep volumes of pelagic habitat found in these two reservoirs. Nearly a decade ago, Arizona and Nevada biologists recommended that hydroacoustics be used to monitor these communities (Persons and Dreyer 1987a,b, NDOW 1994). However, for various reasons an acoustical monitoring program was never fully implemented. This study represents the first attempt to describe the pelagic fishery of either reservoir using acoustic technology.

The Effect Of Mechanical Noise And Natural Sound On Visitor Experiences In Units Of The National Park System, Dr. James Gramann, National Park Service, U.S. Department Of The Interior Jan 1999

The Effect Of Mechanical Noise And Natural Sound On Visitor Experiences In Units Of The National Park System, Dr. James Gramann, National Park Service, U.S. Department Of The Interior

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

This paper reviews research on the effects of mechanical noise and natural sound on visitor experiences in national parks. Three approaches to studying noise impacts are described. Most noise research to date has addressed the impact of air-tour overflights on visitor experiences. these impacts are localized with significant percentages of visitors in some parks reporting interference with natural sounds from aircraft noise. Research also shows that unthreatening natural environments can have significant stress-reducing effects for many people. However, it is unclear if these effects are due to hearing the sounds of nature or to a combination of hearing and seeing …

Water Resources Management Plan: Arches National Park & Canyonlands National Park, Utah, Lynn Cudlip, Kevin Berghoff, David Vana-Miller Jan 1999

Water Resources Management Plan: Arches National Park & Canyonlands National Park, Utah, Lynn Cudlip, Kevin Berghoff, David Vana-Miller

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

The National Park Service recognizes the importance of preserving, conserving, and protecting water resources within its boundaries. Water resources, whether as large as the Colorado River or as small as a seep in Ernie's Country of Canyonlands National Park, play a distinctive role in linking ecosystems and , in general, provide habitat for a number of organisms. To protect park water resources, the Natinoal Park Service initiated a Water REsources Planning Program in 1991. The planning program provides an essential step in developing a comprehensive understanding of a park's hydrological system and the complex resource issues which surround it. The …

The Limits Of Specificity: An Experimental Analysis With Rna Aptamers To Ms2 Coat Protein Variants, Marc Spingola, Ichiro Hirao, David Peabody, Andrew Ellington Jan 1999

The Limits Of Specificity: An Experimental Analysis With Rna Aptamers To Ms2 Coat Protein Variants, Marc Spingola, Ichiro Hirao, David Peabody, Andrew Ellington

Biology Department Faculty Works

It has been hypothesized that selections for aptamers with high affinity for a given target molecule will of necessity identify aptamers that have high specificity for that target. We have attempted to assess this hypothesis by selecting aptamers that can bind to MS2 coat protein or to single- or double-substitution variants of the coat protein. Some aptamers selected to bind MS2 coat protein or its variants were mildly specific for their cognate targets, discriminating by two- to fourfold against closely related proteins. Specificity determinants on both the coat proteins and the aptamers could be identified. However, many aptamers could readily …

Adult Survival And Imperfect Assessment Of Parentage: Effects On Male Parenting Decisions, R. A. Mauck, Elizabeth A. Marschall, Patricia G. Parker Jan 1999

Adult Survival And Imperfect Assessment Of Parentage: Effects On Male Parenting Decisions, R. A. Mauck, Elizabeth A. Marschall, Patricia G. Parker

Biology Department Faculty Works

Applications of molecular methods to assess parentage have revealed that the distribution of reproductive success among individuals often differs, sometimes dramatically, from expectation based on observation of behavioral association. Much theory exists on whether and when males should reduce parental care in response to level of paternity. Life-history theory predicts that trade-offs in reproductive effort should be influenced by adult survival. We used a dynamic programming approach to address how level of paternity, ability to assess paternity, and adult survival rate interact to affect male tolerance of reduced parentage in a given brood. Adult survival has the greatest influence on …

Optimized Calibration For Unsteady Flow Modeling Using A Genetic Algorithm, Daniel Sanchez, Jerome A. Westphal Jan 1999

Optimized Calibration For Unsteady Flow Modeling Using A Genetic Algorithm, Daniel Sanchez, Jerome A. Westphal

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

The calibration of an unsteady flow model generally relies on the estimation of roughness coefficients, which act as descriptors of friction resistance along the channel. Here an optimized procedure is implemented by incorporating a genetic algorithm (GA) to automate the process. This approach is suitable because discrete parameters are considered. The target is a one-dimensional unsteady flow model in which the roughness coefficient is allowed to vary not only along the river axis, but also dynamically with discharge. The objective function is the root mean square of the difference between measured and computed water levels at a given cross section. …

Variability Of Pathogenic Activity Of Entomogenous Fungi (Hyphomycetes) Towards The Legume Flower Thrip Megalurothrip Sjostedti (Trybom)(Thysanoptera:Thripidae) And Their Potential For Biological Control, Sunday Ekesi

All PhD Dissertations

Twenty-two strains of entomopathogenic fungi were tested in the laboratory to determine their pathogenicity to adult Megalurothrips sjostedti (Trybom). All the fungal strains were pathogenic to the insect. Beauveria bassiana and Metarhizium anisopliae strains caused mortality ranging between 29 to 100% and 54 to 100%, respectively. In contrast, VerticiIlium lecanii and Paecilomycesfumosoroseus were less virulent, causing mortality ranging between 29 to 68% and 13%, respectively. The LT50 of the most virulent B. bassiana andM. anisopliae strains was 2.7 and 2.4 days, respectively. The LC50 for the most active B. bassiana strain was 7.9 x 106 conidia ml"1. The LC50 for …

Clarification Of The Hybrid Origin Of Carex X Deamii Herm. (Cyperaceae) Based On Macro And Micro Morphological Characters, Paul B. Marcum Jan 1999

Clarification Of The Hybrid Origin Of Carex X Deamii Herm. (Cyperaceae) Based On Macro And Micro Morphological Characters, Paul B. Marcum

Theses, Dissertations and Capstones

The origin of Carex x deamii Herm. has been in question ever since it was named to science in 1938. Collections of the hybrid have always been associated with C. shortiana Dewey and either C. typhina Michx. or C. squarrosa L.. C. typhina and C. squarrosa are closely related taxa (Section Squarrosae) and often are morphologically similar. Because of this similarity, determining the correct parental species to the hybrid has been extremely difficult. It is known that the hybrid is sterile and only reproduces asexually. Pollen was analyzed to ascertain the viability of all four taxa. This study utilizes both …
