Ecology Of Juvenile Pink Salmon In The North Gulf Of Alaska And Prince William Sound, Jennifer Lynn Boldt

Fisheries

Increased production of salmon in Alaska has been accompanied by a decrease in average body size and decreased wild stocks, indicating a possible density-dependent response to increases in salmon populations and hatchery releases. Pink salmon have a short two-year life cycle and most post-hatch mortality is thought to occur during their first months at sea; therefore, processes in the early marine residence period may determine abundance. Geographic and seasonal patterns in distribution, growth, and condition of juvenile pink salmon during their first months at sea were examined in Chapter 1. The migration of pink salmon from Prince William Sound (PWS) …

Optimal Inseason Management Of Pink Salmon Given Uncertain Run Sizes And Declining Economic Value, Zhenming Su

Fisheries

This is a comprehensive study on the fishery and management system (including the inseason stock abundance dynamics, the purse seine fleet dynamics and the inseason management) of pink salmon (Oncorhynchus gorbuscha) in the northern Southeast Alaska inside waters (NSE). Firstly, we presented a hierarchical Bayesian modelling approach (HBM) for estimating salmon escapement abundance and timing from stream count data, which improves estimates in years when data are sparse by "borrowing strength" from counts in other years. We presented a model of escapement and of count data, a hierarchical Bayesian statistical framework, a Gibbs sampling estimation approach for posterior distributions, and …

The Implications Of Agriculture In Interior Alaska For Population Dynamics Of Canada Geese, Michael William Eichholz

Theses (Unassigned)

Understanding how environmental change affects demography is essential for understanding and managing populations. An anthropogenic change in the environment that has affected wildlife populations is widespread agricultural development. Agriculture has both negatively and positively impacted abundance of species by affecting a variety of vital rates that influence population abundance. In this study, I describe the migration ecology of Canada geese (Branta canadensis) that nest and stage in Interior Alaska. I also describe how the introduction of agriculture has potentially positively impacted population dynamics of Canada geese by increasing nutrient acquisition, thereby improving their fecundity and survival. Two subspecies of Canada …

Brine Percolation, Flooding And Snow Ice Formation On Antarctic Sea Ice, Ted Maksym

Theses (Unassigned)

Modelling studies of brine percolation, flooding, and snow ice formation on Antarctic sea ice were undertaken to (1) determine the influence of brine transport processes on the salinity, porosity, and stable isotopic composition of snow ice and the underlying ice, (2) explain the range of salinities and isotopic composition observed in ice cores, and to provide a better estimate of the contribution of snow ice to the thickness of the winter pack ice, (3) better understand the microstructural controls on brine percolation and its effects on the properties of sea ice, and (4) understand the effects of meteorological forcing on …

Anaerobic Biodegradation Of Benzene Under Environmental Conditions Of Sub -Arctic Groundwaters, Nada Itani Raad

Theses (Unassigned)

This research was conducted to detect and understand the potential for anaerobic degradation of benzene in a sub-arctic aquifer environment. The major hypothesis tested in this dissertation is that indigenous microorganisms from anaerobic groundwater wells contaminated with BTEX (benzene, toluene, ethylbenzene, xylenes) can use benzene as a carbon or energy source under conditions favoring iron- and sulfate-reduction and methanogenesis. To test this hypothesis microcosms were prepared and incubated under anaerobic conditions, with either hematite (Fe2O3) or sodium sulfate (Na2SO4) added to permit growth of iron and sulfate reducing bacteria. Several concentrations of benzene were used as a substrate, and the …

Structure-Function Relationship Of The Developing Acetylcholine Receptor In Amphibians, Michael Patrick Sullivan

Theses (Unassigned)

The nicotinic acetylcholine receptor is responsible for the transfer of signals from the peripheral nervous system to skeletal muscle, resulting in movement. Despite the importance of the acetylcholine receptor, many questions remain unanswered about the relationship between the structure and function of the receptor. The purpose of our research was to explain certain features of the relationship between the amino acid sequence and the function of the amphibian nicotinic acetylcholine receptor. We focused on describing the structural elements underlying the physiologic changes that occur during development and re-innervation of damaged mature muscle. We used molecular biological techniques to alter the …

Daily Meal Patterns, Voluntary Food Intake And Fattening Of Reindeer During Winter And Responses To Insulin, Raphaela Stimmelmayr

Theses (Unassigned)

I determined the effect of insulin injections on daily feeding behavior and voluntary food intake (VFI) in reindeer (Rangifer tarandus t. ) fed a concentrate ration during winter. Food intake in the absence of insulin injections was down regulated and characterized by small, regular meals during daylight and irregular and sometimes large nighttime meals. Each large nighttime meal was associated with a long post-meal interval. Daytime meal size could be predicted from an estimate of the energy deficit incurred since the previous meal; however, the occasional oversized nighttime meals were not predicted from energy deficit and suggested that appetite may …

Heat Increment And Methane Production By Muskoxen Fed Browse, James Patrick Lawler

Biological Sciences

Many browse species contain anti-herbivory compounds that deter consumers by their toxicity or digestive inhibitory effects. Animals that consume browse are assumed to pay a detoxification energy cost, which increases the heat increment of feeding (HIF). Ruminants also lose potentially metabolizable energy as methane (CH4); but browse may lower CH4 production. I hypothesized that increases in energy loss to HIF by animals eating browse could be offset by a reduction in energy lost via CH4 production. Muskoxen eat both graminoids and browse and are considered to be energetically conservative due to their existence in a sparse arctic environment. These traits …

Modeling The Influences Of Climate Change, Permafrost Dynamics, And Fire Disturbance On Carbon Dynamics Of High -Latitude Ecosystems, Qianlai Zhuang

Biological Sciences

A Soil Thermal Model (STM) with the capability to operate with a 0.5-day internal time step and to be driven with monthly input data was developed for applications with large-scale ecosystem models. The use of monthly climate inputs to drive the STM resulted in an error of less than 1�C in the upper organic soil layer and in an accurate simulation of seasonal active layer dynamics. Uncertainty analyses identified that soil temperature estimates of the upper organic layer were most sensitive to variability in parameters that described snow thermal conductivity, moss thickness, and moss thermal conductivity. The STM was coupled …

Alexander Archipelago Wolves: Ecology And Population Viability In A Disturbed, Insular Landscape, David Karl Person

Biological Sciences

The Alexander Archipelago wolf (Canis lupus ligoni) occupies Southeast Alaska, a region undergoing intensive harvest of timber. Sitka black-tailed deer (Odocoileus hemionus sitkensis) are the primary prey of these wolves. We conducted a telemetry study of 23 wolves on Prince of Wales and adjacent islands in Southeast Alaska between September 1992 and October 1995. We examined home range, habitat use, reproduction, mortality, and dispersal of wolves in logged landscapes and those that were relatively unlogged. We used those data to parameterize a wolf-deer model to predict long-term effects of timber harvest on the wolf-deer system on Prince of Wales and …

Univercity News (2001-04-16)

UniverCity News, 1998-2001

VCU Today, the University’s first official administrative organ, began as a somewhat irregular monthly publication but moved to a bi-weekly newspaper format in the 1980s. The newspaper changed its name to VCU Voice in 1988 and ten years later it appeared under the title UniverCity News. As it neared the end of its run as a physical newspaper, the publication became simply VCU News. These four publications were essentially the same periodical published under different titles by the Office of University Relations. VCU News appeared online for the first time in 2002.
