Mudfish On The Menu? Rise Of The Much-Maligned Bowfin, Ken Sulak

United States Geological Survey: Staff Publications

Cajuns call it “choupique” (say “shoe-pick”), from its Choctaw name. Elsewhere, it’s the dogfish, blackfish, grindle, cottonfish, or cypress trout. Its official common name is “Bowfin” (Amia calva)1. But to most anglers, this is the “mudfish,” a strange, unusual, and much-maligned fish, most everywhere considered a useless trash fish. One look and the words relict, prehistoric, primitive, and living fossil come to mind. Indeed, the bowfin is the last of its line, the sole-surviving species of a very ancient group of fishes. Its predecessors flourished in the Jurassic and Cretaceous periods during the Mesozoic (= Middle-Animal) Era, a …

Human Rights, Health And The Environment, David Gillespie

Human Rights & Human Welfare

Environmental health and human rights are inextricably linked. According to the Universal Declaration of Human Rights, Article 3, “Everyone has the right to life, liberty, and security of person.” Given that the earth is the source of the basic necessities of human life, any discussion about health and human rights must be attentive to its inherent environmental aspects. International conventions, documents and reports such as Agenda 21 (1992) and The Draft Declaration of Human Rights and the Environment (1994) have expressly argued for such an integrated approach. In response, a plethora of works over the past decade have expanded the …

Investigation Into The Use Of Bait Stations For The Control Of The European Wild Rabbit (Oryctolagus Cuniculus) In The Urban Bushland Reserve Of Bold Park, Perth, Western Australia, Malin Kordes

Theses : Honours

European rabbits in Australia have a significant impact on the environment and the economy. It is therefore necessary to implement control programs. In rural areas a number of methods including warren ripping and poisoning are frequently used. In urban areas though, rabbit control is not as easily accomplished because the use of many control methods is not appropriate. For example, the poison 1080 often cannot be used due to public health concerns and warren ripping cannot be used in conservation areas. Poisoning with pindone, an anticoagulant, is therefore one of few options available to the managers of urban reserves. However, …

Factors Influencing A Declining Pronghorn Population In Wind Cave National Park, South Dakota, Jaret D. Sievers

Electronic Theses and Dissertations

Pronghorn (Antilocapra americana) were reintroduced into Wind Cave National Park (WCNP) in 1914 and thus, have inhabited the park for almost a century. A decline in the population has raised concern for the continued existence of pronghorn inside the park. Historically, pronghorn numbers reached greater than 300 individuals but were estimated to be less than 50 individuals during this study. Knowledge of food habits, genetic structure, causes of mortality, survival rates, and information related to movements were important to developing an understanding of factors contributing to this decline. Past studies have described spatial relationships and breeding behavior of adults and …

Effects Of Fire On The Nutritional Ecology Of Selected Ungulates In The Southern Black Hills, South Dakota, Teresa J. Zimmerman

Electronic Theses and Dissertations

Research in the 1990s indicated that populations of white-tailed deer (Odocoileus virginianus) in the northern and central Black Hills had declined since the late 1970s likely due to habitat deterioration. In August 2000, the Jasper fire consumed nearly 35,000 ha of ponderosa pine (Pinus ponderosa) forest in the southern Black Hills. To ascertain the nutritional condition of white-tailed deer and mule deer (O. hemionus) and their response to fire, 5 adult white-tailed deer and 5 adult mule deer were collected in burned and unburned habitat, in February and August, 2002 and 2003. Collected deer were weighed and necropsied at a …

Physical, Chemical, And Mechanical Properties Of Bamboo And Its Utilization Potential For Fiberboard Manufacturing, Xiaobo Li

LSU Master's Theses

This study investigated the chemical, physical, and mechanical properties of the bamboo species Phyllostachys pubescens and its utilization potential to manufacture medium density fiberboard (MDF). The result showed holocellulose and alpha-cellulose content increased from the base to the top portion. There was no significant variation in Klason lignin content or ash content from the base to the top portion of the bamboo. The outer layer had the highest holocellulose, alpha cellulose, and Klason lignin contents and the lowest extractive and ash contents. The epidermis had the highest extractive and ash contents and the lowest holocellulose and alpha-cellulose content. Specific gravity …

Comparison Of The Efficiency Of Utilization Of Amino Acids From Intact Protein And Amino Acids In Crystalline Form By Channel Catfish, (Ictaluras Punctatus), Amogh Arun Ambardekar

LSU Master's Theses

Two laboratory feeding trials were conducted to quantify differences in the digestibility and absorption of dietary amino acids provided in intact protein or in purified amino acid mixtures. In the first experiment, 36 channel catfish (346 ± 47 g) were force-fed one of six practical feed ingredients (blood meal, corn meal, fish meal, meat and bone meal, soybean meal or wheat middlings), or a mixture of crystalline amino acids designed to duplicate the amino acid composition of each of the practical ingredients. Apparent digestibility coefficients (ADC) were calculated for 15 amino acids in each practical ingredient and in each amino …

Individual And Landscape-Level Effects Of Selective Herbicides, Mowing, And Prescribed Fire On Habitat Quality For Northern Bobwhite (Colinus Virginianus), Charles Lynn Kitts

LSU Master's Theses

Northern bobwhite (Colinus virginianus) populations have been declining throughout their range during the past 30 years primarily because of a result of loss of early successional habitat. Specifically, intensive silviculture practices and reduction in the use of prescribed fire has led to this loss. I studied effects of management practices (selective herbicides, mowing, and prescribed fire) on male and covey distribution, and brood-rearing habitats on Jackson-Bienville Wildlife Management Area (JBWMA). Specifically, I used calling surveys to assess landscape characteristics associated bobwhite distribution. I also measured vegetation and arthropod response, using imprinted bobwhite chicks, pitfalls, and sweep nets, to different habitat …

Temperature Effects On Spawning And Fingerling Production Of Channel Catfish Ictalurus Punctatus, Patrice Arnold Pawiroredjo

LSU Master's Theses

The goal of this study was to develop several techniques that utilize the use of geothermal water that can contribute to increased profitability for commercial catfish producers. The primary objectives of this study were to: 1) determine the heating requirement using degree-days of channel catfish spawning 2) improve the efficiency of artificial spawning and, 3) evaluate the effectiveness of stocking outdoor ponds and pools with channel catfish fry. The heating requirement for channel catfish spawning was determined to be between 99 and 129 degree days at the peak of spawning. There was no difference in degree-day values between spawns collected …

Feasibility Of Localized Management To Control White-Tailed Deer In Forest Regeneration Areas, Tyler A. Campbell, Benjamin R. Laseter, W. Mark Ford, Karl V. Miller

United States Department of Agriculture Wildlife Services: Staff Publications

The deleterious effects of white-tailed deer (Odocoileus virginianus) on forest regeneration are well documented in many forested systems, but potential solutions to these problems on remote landholdings are limited in number and scope. Localized management proposes that a persistent area (<2 km2) of low density can be created by removing all individuals within matriarchal social groups of white-tailed deer. Our objective was to assess the feasibility of using localized management as a tool within forest regeneration areas. We present a comparison of seasonal home-range and core-area size and site fidelity of 148 radiomonitored female white-tailed deer in a forested landscape of the central Appalachians of West Virginia. We also characterized seasonal movements and dispersal. Adult female winter home-range size exceeded those of summer and autumn. Female deer displayed high fidelity, with home-range and core-area overlap being less in autumn than in summer or winter. Dispersal occurred in 1 of 28 (3.6%) female fawns and no deer >1 year old dispersed. Female white-tailed deer on our study site meet the a priori assumptions of localized management. We assert that experimental manipulations based on localized management concepts are prudent.

A Proposal To Meet The Biofuels Directive In Ireland, Karl Mccarthy

Theses

In 1990 the transport sector accounted for 9,5% of all Irish emissions. By 2010 it is predicted that transport emissions will have increased by 179%, accounting for 18.8% of all emissions. It is predicted that transport emissions will therefore be around 14,000 kt in 2010. This equates to around €370 million pa in carbon taxes if and when the taxation regime is introduced. This €370 million may be used to facilitate a biofuel industry (for example, by reducing excise duty on biofuels).

The proposed carbon tax along with the EU Biofuels Directive aims to encourage the use of renewable transport …

Mortality Of Pen-Raised White-Tailed Deer (Odocoileus Virginianus) Released On Three Areas In Louisiana, Barret Keith Fortier

LSU Master's Theses

I monitored 60 radio-collared and tagged pen-raised white-tailed deer (Odocoileus virginianus) to ascertain mortality rates on three areas in Louisiana from April 2001 - April 2002. Two of 60 were not used in the analysis because mortality occurred from complications with darting and an affixed radio-collar. Study deer were exposed to legal hunting mortality only if they emigrated from the three study areas. Twenty deer were released to the wild on the Louisiana State University Deer Study Area (LSUDSA) (4,810 ha), where 9 of 20 (45%) suffered mortality. Harvest accounted for 56%, vehicles 22%, and other 22% of the mortality …

Seasonal Activity Areas Of Coyotes In The Bear River Mountains Of Utah And Idaho, Glen F. Gantz, Frederick F. Knowlton

United States Department of Agriculture Wildlife Services: Staff Publications

We studied the seasonal movement patterns and dispersal of coyotes (Canis latrans) in the Bear River Mountains of northern Utah and southern Idaho to determine whether coyotes in this montane region exhibit an altitudinal migration on a seasonal basis. We used 3 locational parameters to assess whether a seasonal altitudinal migration was evident, including overlap in seasonal activity areas, distance between harmonic mean centers of activity, and seasonal differences in mean elevations of locations. Winter and summer activity areas of every mature coyote overlapped, with mean distances between harmonic centers of seasonal activity of 1.5 km (range = 0.4–3.3 km). …

Predacides For Canid Predation Management, K. A. Fagerstone, J. J. Johnston, P. J. Savarie

United States Department of Agriculture Wildlife Services: Staff Publications

Throughout the livestock industry in the western United States, control of canid predators was considered to be of considerable importance to the livestock industry, especially to sheep producers, who sufkred high losses from coyotes and wolves. In the 19th century, the demand for predator control was communicated to Congress and the western state assemblies, with the result that predator control was provided in western states by the Fedcral Bureau of Biological Survey in cooperation with state agencies, and by trappers hired by stockmen. Steel traps and poisons were the principal methods used for predator control during the early years of …

Evaluation Of Growth, Production And Cold Tolerance Of Four Varieties Of Tilapia, Patricio Enrique Paz

Effect Of Heavy Metals On Bacteria, Elena Vratonjic

Theses and Dissertations

Heavy metals have become devastating environmental contaminants due to their widespread use in the manufacture of electronics, plastics, batteries and dyes. The discharge of heavy metals into the environment has caused concern about their effects on the ecosystem. Many metals are essential for growth in small amounts. However, at higher concentrations heavy metals are toxic because they bind to organic compounds. This accounts for their effects on some important parts of the cell structure, like their ability to denature protein molecules. The initial objective of this study was to find out the growth rate of E.coli and M.roseus in the …

Survey Of Health Effects Among Residents Adjacent To A National Priority List Site In Ssouthwest Virginia., Danette Haywood

Electronic Theses and Dissertations

The Saltville Waste Disposal Site is a National Priority List site used during the 77- year operation (1895–1972) of an electrolytic chlorine and caustic soda plant. A cross-sectional study was conducted to determine disease prevalence among Saltville Medical Center (SMC) patients. Diseases associated with chronic exposures to mercury, arsenic, and lead were reviewed in patient records and these data were analyzed. Ratios of illness observed at the SMC were compared to health studies of similar environmental exposures and disease prevalence among residents of neighboring communities. Prevalence ratios were calculated for residents and non-residents of Saltville who were SMC patients. Saltville …

Understanding Blackbird Sensory Systems And How Repellent Applications Work, Scott J. Werner, Larry Clark

United States Department of Agriculture Wildlife Services: Staff Publications

We reviewed the learning processes and sensory capabilities of birds, with a special emphasis on chemical repellents and wildlife damage management. Repellents include several methods and devices used to manipulate behavior of birds in attempt to reduce damage or nuisance. Effective applications of chemical repellents to reduce bird damages are dependant upon an adequate understanding of the sensory modalities and modes of animal learning that are affected by a repellent. Chemical repellents can elicit withdrawal from specific or combined sensory stimuli or by producing learned avoidance via association between adverse postingestive effects and specific sensory cues. The application of repellents …

We have observed large fluctuations in Tampa Bay fish populations over the last decade, and these changes may be associated with the environment, management practices, or other factors. Staff of the Florida Fish and Wildlife and Conservation Commission’s Fish and Wildlife Research Institute began developing the Fisheries-Independent Monitoring (FIM) program in 1988 and have monitored fish populations in Tampa Bay continuously since 1989. Various types of sampling gear have been utilized during the history of FIM, but 21.3-m bag seines have been used since the beginning of the program. This small seine is effective at capturing juveniles of many economically …

Reviews Of Fatal Harvest: The Tragedy Of Industrial Agriculture And The Fatal Harvest Reader: The Tragedy Of Industrial Agriculture, Edited By Andrew Kimbrell, Charles A. Francis

Great Plains Research: A Journal of Natural and Social Sciences (through 2013)

Fatal Harvest introduces and dispels key myths about industrial agriculture: greater efficiency; safe and nutritious food that is cheap to consumers; benefits to wildlife and environment; how biotechnology will save the world. In essays by leading proponents of a more equitable and sustainable food system, the book presents compelling evidence that alternative systems guided by an agrarian ethic will better address our food needs while protecting our natural environment and soil resources.

Wendell Berry cites the separation of people from their food supply and natural environment as a causal factor in our ready acceptance of today's industrial agriculture. When we …
