The Ecology Of Parafluvial Ponds On A Salmon River, Zachary Jon Crete

Graduate Student Theses, Dissertations, & Professional Papers

Parafluvial ponds are discrete lentic habitats embedded in the alluvia of gravel bed rivers that are formed by flooding and persist in relation to floodplain geohydrology. On the expansive flood plains of the Kwethluk River, I observed thousands of juvenile salmon apparently trapped by surface disconnection of the ponds from the river. I was interested in whether the salmon could survive until flooding reconnected the ponds to the river. I sampled ponds along the river corridor to describe habitat quantity and juvenile salmon presence, growth, and diet. Furthermore, I looked at pond hydrology, temperature regime, and the role groundwater plays …

The Effect Of Random And Spatially Explicit Lightning And Human-Caused Ignitions On Simulated Burn Probabilities At Small Scales, James Lowery

Graduate Student Theses, Dissertations, & Professional Papers

Our overall goal was to assess the difference between annual wildfire burn probability (BP) generated from simulation models using random ignitions versus spatially explicit ignitions for wildland urban interface (WUI) areas and designated wilderness in the Rocky Mountain West, and infer whether one may be more useful than the other at small scales. We collected all available ignition data from logbooks, spreadsheets and the internet for a 1282 km2 study area within a 10 km buffer of the Rattlesnake National Recreation Area (RNRA) and Rattlesnake Wilderness (RW), Montana, which also included WUI. These ignitions were on small private landholdings, as …

Trading Off The Benefits And Burdens: Coal Development In The Transboundary Flathead River Valley, Nadia E. Soucek

Graduate Student Theses, Dissertations, & Professional Papers

The potential for coal development in the transboundary Flathead River Valley threatened the ecological integrity of the Crown of the Continent for more than thirty years. Economic benefits from coal mining in British Columbia were pitted against the environmental concerns of poor water quality, endangered species protection, and connectivity issues were of particular interest in Montana. This paper examines the course of coal development proposals in the transboundary valley through government statements, reports, and news sources to track changes in policies or actions that led to a resolution. Tensions between the benefits and burdens of coal development were resolved in …

Understanding Incubator Farms: Innovative Programs In New Farmer Development, Brianna M. Ewert

Graduate Student Theses, Dissertations, & Professional Papers

With the average age of farmers climbing close to retirement and an increased demand for locally and sustainably grown food, there is a great need for new and beginning farmers, particularly those engaged in alternative production practices. But the barriers to entry for these new farmers are high; land access, start up costs, finding a spot in the market, and a lack of social support all pose challenges. The last few years have seen an increased interest in supporting beginning farmers and the creation of new programs to do so. Incubator farms are one such promising strategy. Incubator farms are …

Upper South Fork Of The Flathead Users: What Social Setting Attributes Are The Most Important?, Forest Waters Moulton

Graduate Student Theses, Dissertations, & Professional Papers

Previous research has shown that wilderness visitors place much value on an uncrowded social recreation setting. However, the current indicators that the Flathead National Forest has implemented to monitor this setting on the upper South Fork of the Flathead River may not satisfy several of the qualities of a good indicators, particularly “significance.” In an attempt to recommend new indicators to monitor opportunities for quality experience within this social setting, this study assessed the significance or importance of several alternative social setting attributes. It also attempted to provide meaningful qualifications to these evaluations by analyzing variation in three concepts associated …

What They Consider, How They Decide: Best Practices Of Technical Experts In Environmental Decision-Making, Cassandra J. Hemphill

Graduate Student Theses, Dissertations, & Professional Papers

Drawing from qualitative data gathered from environmental management professionals, this paper describes best practices for decision-making in environmental clean-up. Technical experts are knowledgeable about both cultural and technical rationality and employ both, as appropriate, to achieve more robust decisions. Experts use active, passive, and interactive communicative strategies to reduce uncertainties and manage tensions. Deliberation is used to achieve robust decisions. The analysis suggests that organizations can improve acceptability of decisions by authorizing experts to incorporate cultural rationality early in the decision process.

The Changing Role Of Sámi Women In Reindeer Herding Communities In Northern Norway And The 1970-1980s Women’S Resistance And Redefinition Movement, Marcie Kaye Bremmer

Graduate Student Theses, Dissertations, & Professional Papers

Historically, different nations-states at different times have tried to claim authority over the Sámi in the circumpolar north. After the nation state borders were drawn in the 1700s and 1800s, separating Russia, Norway, Sweden and Finland, Norway introduced a harsh and 1800s separating Russia, Norway, Sweden and Finland, Norway introduced a harsh assimilation policy that lasted over a century. Cultural Darwinist views and national assimilationist legislation and social strategies chipped away at Sámi society and its identity as an indigenous people. Over time Sámi women found their accustomed social, economic, and political autonomy eroded. Post World War II, the emerging …

Risk Magnified: Standing Under The Statist Lens, Mary D. Fan

Articles

Why some harms count before the courts and others do not is a matter of acute expressive and practical impact. Judicial refusal to see claimed injuries is an effective denial of legal personhood and a bar from powerful judicial machinery. The issue of “erratic, even bizarre” judicial recognition of supplicants vexed Professor Joseph Vining as early as 1978. Recent scholarship argues that injuries are seen through a subjective lens, reflecting the relative privilege of the judiciary and their concomitant difficulties in perceiving injuries to minorities and the poor. This is a troubling contention. So long as another, objective explanation remains, …

The Colonial Legacy Of Environmental Degradation In Nigeria's Niger River Delta, Joseph England

Electronic Theses and Dissertations

Nigeria’s petroleum industry is the lynchpin of its economy. While oil has been the source of immense wealth for the nation, that wealth has come at a cost. Nigeria’s main oilproducing region of the Niger River Delta has experienced tremendous environmental degradation as a result of decades of oil exploration and production. Although there have been numerous historical works on Nigeria’s oil industry, there have been no in-depth analyses of the historical roots of environmental degradation over the full range of time from the colonial period to the present. This thesis contends that the environmental degradation of Nigeria’s oil producing …

Stem Future Dallas, Jacob Fleming, Alex Saucedo, Jessica Hart

Big iDeas 2012 Proposals

In 1993, the proposed Superconducting Super Collider (SSC) project of Waxahachie, Texas, was cancelled. This massive structure would have been three times as large as the recently completed Large Hadron Collider in Geneva and many times more powerful. With its cancellation, two generations of physics progress have been lost for the United States. This singular event is epitomical of a broader set of issues in the United States; namely, the issues of science, technology, engineering and math (STEM) education, their funding, and research and development in these fields.

In the second decade of the 21st century, we face a continuation …

Protecting The Public From Bpa: An Action Plan For Federal Agencies, Noah M. Sachs

Law Faculty Publications

Bisphenol-A (BPA) is a ubiquitous industrial chemical found in everything from baby bottles to cash register receipts. From its inauspicious creation in the laboratory by a group of scientists trying to synthesize an estrogenic compound for the pharmaceutical industry, it has become a fundamental building block of the multi-billion dollar plastics industry. Unfortunately, ever since anomalous results appeared in two research labs using BPA containing plastic equipment in the 1980s, evidence of the chemical’s toxicological risks has continued to mount. The chemical is an endocrine disruptor, meaning that it interferes with the body’s hormone system, and BPA’s health risks include, …

Weeks, Takashi Yamada, Alexandre Lomsadze, Mark Borodovsky, Jean-Michel Claverie, Igor V. Grigoriev, James L. Van Etten

Department of Plant Pathology: Faculty Publications

Background: Little is known about the mechanisms of adaptation of life to the extreme environmental conditions encountered in polar regions. Here we present the genome sequence of a unicellular green alga from the division chlorophyta, Coccomyxa subellipsoidea C-169, which we will hereafter refer to as C-169. This is the first eukaryotic microorganism from a polar environment to have its genome sequenced.

Results: The 48.8 Mb genome contained in 20 chromosomes exhibits significant synteny conservation with the chromosomes of its relatives Chlorella variabilis and Chlamydomonas reinhardtii. The order of the genes is highly reshuffled within synteny blocks, suggesting that intra-chromosomal rearrangements …

Cameras, Satellites, And Surveys: A Multi-Platform Approach To Monitoring Lake Conservation Behavior, Daniel D. Homeier

Honors Theses

Shoreline buffers are essential to maintaining lake water quality and there are numerous methods for their assessment. There is uncertainty in the benefits and drawbacks of different shoreline buffer assessment methods. In this study I explore three methods of remotely assessing shoreline buffers in the Belgrade Lakes Region of Maine: household surveys, geotagged shoreline photos, and satellite imagery. By comparing these three methods I will evaluate their accuracy and applicable scale when used to assess the presence and quality of shoreline buffers.

I used both parametric and non-parametric analysis to (1) evaluate the relative accuracy of 154 household surveys in …

Isolation And Purification Of Glutathione S-Transferases (Gsts) From Orbicularia Orbiculata / Marini Binti Ibrahim, Marini Ibrahim

Student Works (2010-2019)

Glutathione S-transferases (GSTs) in bivalves which belong to the phase II detoxification metabolism, have an advantage to be used as biomarkers of aquatic pollution. The preliminary study was to isolate and purify the GSTs from Malaysian bivalve, Orbicularia orbiculata or locally known as Siput Lala. The GST enzyme was purified by using two different matrices of affinity chromatography which were GSTrapTM HP and GSH-agarose (C3). Total proteins attained from both eluates were 0.24±0.003mg and 0.12±0.07mg for GSTrapTM HP column and GSH-agarose (C3) column, respectively. Of the enzyme activity, 18% was retained on the GSTrapTM HP column and gave purification factor …

The Geography Of Greenhouse Gas Emissions From Within Urban Areas Of Asia, Jochen Albrecht, Peter Marcotullio, Andrea Sarzynski, Niels Schulz

Publications and Research

This paper aims to advance two objectives: (1) identify and explore greenhouse gas emissions from urban areas in Asia at the regional level; and (2) explore covariates of urban greenhouse gas emissions. We use the Emissions Database for Global Atmospheric Research estimates for carbon dioxide, methane, nitrous oxide, and sulfur hexafluoride from 14 source activities for the year 2000, which are allocated on a 1/108 global grid. We extract emissions for 3535 urban extents all with populations over 50,000, accounting for approximately 91% of the region’s urban population. We use regression analysis to associate emissions with urban area and growth, …
