Seven experiments were performed to assess the use of glucose responses to insulin injections as a means of estimating insulin sensitivity in horses; to compare the insulin sensitivities of normal horses vs. those displaying hyperleptinemia; and to put this method into practical application. Experiment 3.1 examined dose-responses in mares of potentially different insulin sensitivities. Recombinant human insulin was injected at doses of 8, 20, 50, and 125 mU/kg BW, as needed, to estimate the dose...

Understanding patterns of dispersal, the movement of individuals or propagules, among populations of riverine species is imperative to their management and conservation. However, directly estimating dispersal can often be difficult. Therefore, estimates of gene flow, the movement of genes, are often used to infer dispersal among natural populations. In riverine species, gene flow is determined by species biology, riverine architecture and flow regime. While many studies investigate the role of s...

The growing demand for water in the arid regions of the West increases the need for optimal allocation of water among competing uses. An efficient allocation of water between instream and out-of-stream uses has been impeded by institutional constraints and the scarcity of information regarding instream flow benefits. The objectives of this thesis were to provide preliminary economic data on the value of instream water in "producing" recreational fishing and to examine the effect of forestry, agr...

Mass transfer processes in food systems, such as solute infusion, are poorly understood because of their complex nature. Food systems contain porous matrices and a variety of continuous phases within cellular tissues. Mass transfer processes are generally not pure diffusion: often convection, binding and obstructing diffusion will occur. Monte Carlo (MC) simulation has been increasingly used in life science and engineering to elucidate molecular transport in biological systems. However, there ar...

Twenty-three bottom-trawl fish assemblages were identified from the relative biomass of 33 dominant species that occurred in the National Marine Fisheries Services' triennial trawl surveys over the continental shelf and upper slope off California, Oregon, and Washington from 1977 to 1992. The assemblages accounted for about 70% of the total variation in species composition among 2,565 hauls. Although the assemblages persisted over the 15-yr study period and occurred within broad geographic bound...

The armoring of river banks with riprap can have detrimental effects on lotic ecosystems due to the subsequent alteration of hydrologic regimes; however, evidence suggests that riprap can also increase aquatic diversity in degraded systems. The goal of my study was to determine what impacts riprapped banks have on fish and macroinvertebrate assemblages in the Pearl River, which has a history of anthropogenic degradation. I collected fishes with an electrofishing boat from armored and natural ban...

In this thesis I have investigated the effects of invading top and intermediate consumers in a size-structured fish community, using a combination of field studies, a lake invasion experiment and smaller scale pond and aquaria experiments. The lake invasion experiment was based on introductions of an intermediate consumer, ninespine stickleback (Pungitius pungitius L.), in to allopatric populations of an omnivorous top predator, Arctic char (Salvelinus alpinus L.). The invasion experiment was pe...

<p> <i>Mycobacterium marinum</i> is an established surrogate pathogen for <i>Mycobacterium tuberculosis</i> because of <i>M. marinum </i>'s strong conservation of thousands of orthologous genes, lower risk, lower financial burden to researchers, and similar pathology in fish. This pathogen causes TB-like chronic disease in a wide variety of fish species and can mount superficial infection of human tissues. As in human TB, the microbe grows within the host macrophages, can mount life-long chronic...

The fossiliferous sediments of the Hueso and Tapiado formations exposed in the Vallecito Creek-Fish Creek section (VCFC) of the Anza-Borrego Desert (ABD) span the boundary between Blancan and Irvingtonian North American Land Mammal 'Ages.' Historically, the determination of the Blancan-Irvingtonian (B-I) boundary in the VCFC proved problematic. A new study to determine the B-I boundary in the VCFC revealed data inaccuracies in both published works and curatorial records of the mammal and other ...

The issue of sustainability has greatest significance in the midst of unilateral bio-socioeconomic degradation resulting from intense and increasing societal pressures placed on the unified global ecology. In such an environment, sustainable development seeks to manage natural resources within a free market economy, aiming to meet the needs of today's population, and to protect and enhance current resource quality and abundance. In this light, techniques of integrated sustainable primary product...

In the early 1990s polychlorinated dibenzo-p-dioxin (PCDD) and dibenzofuran (PCDF) contamination of fish was widely associated with bleached kraft pulp mills. Regulations were put into place in Canada and elsewhere to reduce or eliminate the presence of these chemicals in pulp mill effluents. The industry quickly introduced treatment and process changes such as elemental (ECF) and total chlorine free (TCF) bleaching, which resulted in dramatically reduced PCDD/F concentrations in pulp mill efflu...

Tetrabromobisphenol A, (TBBPA or Br4BPA), is a widely used brominated flame retardant (BFR). Although TBBPA and its breakdown products been found in river sediments, the environmental impact of their contamination is largely unknown. One breakdown product of TBBPA is bisphenol A (BPA), which has been studied intensively for its toxicology because it is used in the manufacturing of plastics and leaches from food containers, water bottles and pipes. Other breakdown products of TBBPA include tribr...

With over ~2600 oil and gas platforms (platforms) remaining in the northern Gulf of Mexico (Gulf), the Gulf States have access to one of the most unique fisheries in the world. Because of high abundances of game fishes around platform legs and the popular belief that platforms enhance fish stocks, both Louisiana and Texas have created artificial reef programs based upon the decommissioning of platforms. As oil and gas fields continue to be retired, oil and gas companies may find that reefing or ...

Modifying milk fat composition to enhance its content of valuable fatty acids (FA) is required to meet the needs of a society which is becoming better informed about the relationship between diet and health. Manipulating the cow’s diet is an effective, natural way to modify the amount and composition of milk fat of cows. The two main factors that affect the cow’s diet concern management system (MS; pasture vs. confinement), and supplementation of diets with lipid supplements. Marine oils specifi...

This thesis introduces a " new " international relations theorist who is also, in fact, one of the oldest of international relations theorists. Mencius (Meng Zi 371-289 BCE) is well known to students of Chinese culture as a key figure in the history of Confucianism and in the history of China: the second sage no less. Yet modern scholars usually study him, if he is studied at all, for an idea of how " Chinese" think rather than as a thinker worth studying for his own sake. I decided ...

This work is a baseline study of the relationship between the fish fauna at Eden Lake and the surrounding rocks. A broad suite of trace elements is incorporated into the otoliths of fish in their natural habitat where the only source of these trace elements is the local geology. Eden Lake is underlain by the Eden Lake Complex. The Eden Lake Complex is a monzonitic intrusion associated with pegmatite veins containing rare element-bearing minerals such as britholite, allanite and titanite. These ...

Acid rock drainage (ARD) and associated metal leaching (ML) is a major pollution problem throughout the world, adversely affecting both surface and ground waters. The elevated concentrations of metals in the water column due to ARD/ML can be transferred to abiotic and biotic components of an ecosystem and adversely affect the health of aquatic life. The Pennask Creek watershed, one of the most important rainbow trout-producing environments in British Columbia (BC), has been contaminated with ARD...

In many rivers, dams have interrupted the connectivity of migration routes for fish. While fishways can provide access between downstream and upstream habitats, it is important that passage can occur with minimal delay, energy expenditure, and physiological stress. The research presented here is based on investigations into fishway attraction and passage for the Gates Creek sockeye salmon (Oncorhynchus nerka, Walbaum) stock at the Seton River dam in British Columbia. The first part of this th...

BACKGROUND: Fish consumption and intake of omega-3 fatty acids from fish are associated with a lower risk of cardiovascular disease. However, a prospective study from northern Sweden showed that high consumption of fish is associated with an increased risk of stroke in men, but not in women. The current study aimed to determine if fish consumption is differently related to lifestyle in men compared with women in northern Sweden. METHODS: Lifestyle information on 32,782 men and 34,866 women (aged...

We have previously shown that dietary fish oil and fiber, particularly the highly-fermentable pectin, are protective against colon cancer in a rat model of carcinogenesis. Therefore, based upon the current body of literature and our previous experimental findings, we hypothesized that one mechanism by which dietary fish oil+pectin suppress the promotion stage of colon cancer is through butyrate, the fermentation product of fiber, targeting (in particular) the p21Waf1/Cip1 gene and, via targeted ...

This essay focuses on the alienation experienced by Rusty-James in S.E. Hinton’s Rumble Fish (1975). It more specifically centers on the causes of his alienation and how the alienation is illustrated in the novel. The analysis shows that the alienation Rusty-James experiences is caused partly by socioeconomic factors; for example his lack of hope for the future is closely connected to the fact that he belongs to a low socioeconomic class. In addition, there are also psychological factors, for ex...

Under the growing demand for marine fish resources, and the apparent and expected impacts of global climate change, there is a need to conduct long-term monitoring (LTM) to ensure effective management of resources and conservation of biodiversity. However LTM programmes often suffer from design deficiencies and fail to achieve their objectives. These deficiencies stem from the fact that insufficient consideration is afforded to the design phase, with programmes selecting methods that are not sui...

Understanding why fish move the way in which they do has applications far outside of biology. Biological propulsion has undergone millions of years of refinement, far outpacing the capabilities of anything created by man. Research in the areas of unsteady/biological propulsion has been increasing in the last several decades with advances in technology. Researchers are currently conducting experiments using pitching and heaving airfoils, mechanized fish, and numerical fish. However, the surrogate...
