Dam Design For Pastoral Stock Water Supplies, J S. Addison, R J. Law, G B. Eliot

Bulletins 4000 -

These notes provide information on many components of water harvesting storage systems designed for use in semi-arid areas. The notion of a water harvesting and storage system is deliberately emphasised. No single design component can be considered in isolation if the goal of a drought-proof water supply is to be achieved.

A drought-proof surface water supply is achieved by integrating the many design components of a water harvesting/storage system into a practical plan.

Habitat Associations Of Rare Species: A Case Study Using Columbia Spotted Frogs (Rana Luteiventris) In Utah, Nathan E. Welch

Biology

Conservation plans benefit from basic ecological information about factors that limit the distribution of focal species. This study illustrates two observational approaches used to investigate the ecology of the Columbia spotted frog (Rana luteiventris), a rare species in Utah. First, hypothesized frog-habitat associations were evaluated by comparing occupied and apparently unoccupied ponds. Data were analyzed using Akaike's Information Criterion to quantify evidence for hypotheses and to select predictive models. Although variable, results suggest frogs are more likely to be found in ponds that do not shrink in size seasonally, maintain a relatively constant seasonal water temperature, and have …

The Behavioral And Chemical Ecology Of A Predator That Consumes Toxic Prey, Becky L. Williams

Biology

The Common Garter Snake (Thamnophis sirtalis) preys upon the Rough-skinned Newt (Taricha granulosa), which contains tetrodotoxin (TTX). I investigated how snakes consume potentially deadly newts and the consequences thereof. Individual snakes assess their resistance relative to newt toxicity and reject prey too toxic to consume. Behavioral moderation of toxin exposure provides the association between individual resistance and fitness necessary for the coevolution of lethal toxins and resistance. After newt consumption, snakes experience tremendous toxin loads. Because TTX is extremely toxic, present in large quantities in newts, and highly resistant snakes ingest multiple newts, snakes can harbor …

Exact Moment Calculations For Genetic Models With Migration, Mutation, And Drift, Rongwei Fu, Alan E. Gelfand, Kent E. Holsinger

EEB Articles

Using properties of moment stationarity we develop exact expressions for the mean and covariance of allele frequencies at a single locus for a set of populations subject to drift, mutation, and migration. Some general results can be obtained even for arbitrary mutation and migration matrices, for example: (1) Under quite general conditions, the mean vector depends only on mutation rates, not on migration rates or the number of populations. (2) Allele frequencies covary among all pairs of populations connected by migration. As a result, the drift, mutation, migration process is not ergodic when any finite number of populations is exchanging …

The Persistence Of Ecological-Economic Systems: Alternate Measures And Their Properties, Amitrajeet A. Batabyal

Articles

A number of ecologists and some economists have commented on the significance of persistence as a stability concept for jointly determined ecological-economic systems. This notwithstanding, the economics and the regional science literatures have paid scant attention to the problem of computing an ecological-economic system’s persistence. As such, this paper has two objectives. First, we derive three measures of the persistence of a jointly determined ecological-economic system whose temporal behavior is governed by the presence of thresholds. Next, we compare and contrast these three measures. Finally, we discuss their theoretical properties and their practical uses.

Assessment And Modeling Of Stream Mitigation Procedures [2003], Bernadette S. Dupont, Sudhir Palle

Kentucky Transportation Center Research Report

As population increases, so does the need to improve and augment the road network. Construction of new roadways or modification of existing roads often requires diversion or modification of streams. If a stream is disturbed, government regulations require mitigation or compensatory replacement of the affected area in a similar environment. Stream mitigation is of particular importance in Kentucky, as Kentucky ranks second in the United States for having the most miles of waterways. Consequently, stream mitigation has become a significant factor in roadway construction costs. To date, no studies have been made to assess the execution of the mitigation plans …

The Effect Of Pedicel Length In Regulating Seed And Wasp Production In The Fig-Wasp Oblígate Mutualism Of Ficus Tuerkheimii (Moraceae) And Agaonidae., May 2003, Tova Jacobovits

Monteverde Institute: Tropical Ecology and Conservation

Pedicel and style lengths of fig flowers were measured in order to determine their role in regulating seed and wasp production within a Ficus tuerkheimii fig. Figs were collected in two groups at two different stages in development. Foundress number, foundress ovipositor length, pedicel lengths, and style lengths were measured (to the nearest micrometer) in the younger figs. Flower pedicel lengths were measured (to the nearest micrometer) and flower occupancy was recorded in mature, but unripe figs. Young figs: In a sample size of 10 young figs, 60% had two foundresses, 20% had one, and 20% had three. The average …

Tree Size And Habitat Effects On Stream Gall Abundance In Conostegia Oerstediana (Melastomataceae), May 2003, Priya Shashidharan

Monteverde Institute: Tropical Ecology and Conservation

The moth Mompha sp. (Coleophoridae, Lepidoptera) is known to induce a stem gall on the tree Conostegia oerstediana (Melastomataceae). There is little known about the distribution and abundance of galls. This study tested the difference in stem gall abundance between varying tree sizes and between two different habitats- pasture and secondary forest. Trees from each habitat were sampled and measured for diameter at breast height (DBH), height, number of branches, and number of galls. A significant difference was found between pasture and forested areas (unpaired t-test, p < 0.0001), with pasture trees having more galls. No relation was found relating tree size (DBH, height, number of branches) to gall abundance. I conclude from these results that tree size is not directly related to stem gall abundance. Instead, differences in habitats, such as predator and parasite abundance and host density, may be important factors that influence gall abundance.

Distinctively Christian Perspectives On Legal Thought?, Mark Tushnet

Michigan Law Review

The plural in the title of Christian Perspectives on Legal Thought immediately suggests one problem in reviewing this collection of essays: identifying unifying themes is difficult precisely because there are a variety of Christian perspectives represented here. Christian perspectives include those of Anabaptists and their modern successors such as Mennonites (who regard law as simply irrelevant to their Christianity), those of the nineteenth-century Catholic church (which was hostile to democracy and religious toleration), and those of the modern Catholic church (which endorses religious pluralism and the preferential option for the poor - among many others). What, then, might be distinctive …

Assessing The Benefits Of Misting–Cooling Systems For Growing/Finishing Swine As Affected By Environment And Pig Placement Date, Thomas C. Bridges, Larry W. Turner, Richard S. Gates, Douglas G. Overhults

Biosystems and Agricultural Engineering Faculty Publications

The NCPIG swine growth model was used to evaluate swine growth performance for Wilmington, North Carolina; Bardstown and Mayfield, Kentucky; and Oklahoma City, Oklahoma as influenced by the use of a misting–cooling system. Five pig placement dates (Julian days 106, 126, 146, 166, and 186) were evaluated for each location using 22 years of weather data (1978–1999). The use of a misting system, while quite variable, was found to be generally profitable, reducing the length of the time to reach market weight. As the placement date increased, the average return to misting ($/pig/year) decreased from $8.12 to $1.98 for Oklahoma …

Continuing Studies Of Water Quality In Farmington Bay And The Great Salt Lake, Utah, Amy M. Marcarelli, Wayne A. Wurtsbaugh

Watershed Sciences Faculty Publications

For the past three years, an Aquatic Ecology Practicum class at Utah State University has conducted research examining the limnology of Farmington Bay. In 2000, our class discovered that Farmington Bay could be classified as hypereutrophic, and had significantly higher levels of chlorophyll and phytoplankton than the Great Salt Lake proper (Marcarelli et al. 2001). In 2001, individual student projects identified high phosphorus loading into Farmington Bay from surrounding sewage treatment plants, brine shrimp biomass five times lower than in the Great Salt Lake, and that the water in the bay lost all oxygen on a windy night in October …

The Curricular Practices Of Early Childhood Teachers Working In Public Sschool Primary Grades., Elizabeth Ely Brading

Electronic Theses and Dissertations

Little is known about the curricular practices or thinking of early childhood teachers attempting to use developmentally appropriate practices in public school primary grades. The purpose of this study was to investigate four primary grade teachers' thoughts and classroom practices, through observation, interviews, and classroom schedules. Data were analyzed following the procedures for open, axial, and selective coding as explained by Strauss (1987). All four teachers exhibited common elements: educational beliefs consistent with those of the National Association for the Education of Young Children; frustration with their school's curriculum; and the combination of a rich pattern of guidance strategies in …

Production Of The Siderophore 2,3-Dihydroxybenzoic Acid Is Required For Wild-Type Growth Of Brucella Abortus In The Presence Of Erythritol Under Low-Iron Conditions In Vitro, Bryan H. Bellaire, Philip H. Elzer, Cynthia L. Baldwin, R. Martin Roop

Faculty Publications

Production of the siderophore 2,3-dihyroxybenzoic acid (2,3-DHBA) is required for the wild-type virulence of Brucella abortus in cattle. A possible explanation for this requirement was uncovered when it was determined that a B. abortus dhbC mutant (BHB1) defective in 2,3-DHBA production displays marked growth restriction in comparison to its parent strain, B. abortus 2308, when cultured in the presence of erythritol under low-iron conditions. This phenotype is not displayed when these strains are cultured under low-iron conditions in the presence of other readily utilizable carbon and energy sources. The addition of either exogenous 2,3-DHBA or FeCl3 relieves this growth defect, …
