Sluice Boxes On The Shores: An Environmental History Of Gold Mining On Oregon's South Coast, Tania Louise Hyatt-Evenson

Dissertations and Theses

Environmental historians have researched, analyzed, and concluded that gold mining significantly altered the environment in Southern Oregon. Environmental case studies have examined mining's impact on the watersheds in the Rogue Valley, but none have analyzed the effect gold miners had on the Southern Oregon coast. While gold mining occurred on the South Coast from the 1850s to the 1940s, on a smaller scale, the impact from environmental change is just as significant. The purpose of this study is to understand how mining changed the landscape of the South Coast, and how this change affected the human populations that lived in …

Potential Of Modis Evi And Surface Temperature For Directly Estimating Per-Pixel Ecosystem C Fluxes, Abdullah Rahman, Daniel A. Sims, Vicente D. Cordova, Bassil Z. El-Masri

School of Earth, Environmental, & Marine Sciences Faculty Publications

We tested the potential of estimating per-pixel gross primary production (GPP) directly from the MODIS enhanced vegetation index (EVI) and respiration directly from MODIS surface temperature (MOD11). Carbon flux data were obtained from 10 eddy covariance tower sites representing a wide range of North American vegetations. The correlation between across-site tower GPP and EVI was comparable (r = 0.77) to that between tower GPP and MOD17-GPP (r = 0.73), suggesting that EVI could be used to provide reasonably accurate direct estimates of GPP on a truly per-pixel basis. There was also a strong relationship (r2 = 0.67) between respiration and …

Maximum Size Of Fish Caught With Standard Gears And Recreational Angling, Kevin L. Pope, Gene R. Wilde, Daryl L. Bauer

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

We correlated maximum lengths of freshwater fishes captured during 10 years with standard gears (i.e., gill nets, boat electrofishers and trap nets) and angling from Nebraska water bodies to determine which methodology provided better estimates of maximum size of fishes produced within a given water body. In general, maximum length of fishes captured with standard gears was smaller than maximum length of fishes captured with angling. Although significant (based on sequential Bonferroni adjustment) correlation was found in only one of nine sport fishes assessed, all correlations were positive indicating a general trend between maximum size of fishes captured with these …

Assessment Of Human Health Risks From Chemically Contaminated Lake Fishes In Greece, Eugene G. Maurakis, David V. Grimes, Dimitra Bobori, Rob Hale, Jennifer Jones

Virginia Journal of Science

Objectives were to conduct screening level surveys of locally consumed fish tissues in vicinities of two lakes (Kastoria and Pamvotis) in Greece to determine the presence of halogenated organic compounds and determine carcinogenic and non-carcinogenic human health risks associated with the consumption of sampled fish tissues. Results estimate the Incremental Lifetime Cancer Risks (ILCR) and Hazard Index (HI) values for the two local populations using site-specific population data. These results were compared to analyses conducted using U.S. Environmental Protection Agency default values in an effort to determine the applicability of USEPA default values to assessments of risks in non U.S. …

Coral Reef Tourism And Conservation In Bocas Del Toro: An Analysis Of Ecotourism And Its Tour Guide-Based Components, Rebecca Kayes

Independent Study Project (ISP) Collection

Tourism of the coral reefs in Bocas del Toro is an important economic activity but also potentially harmful to the environment, creating an ecologically and economically unsustainable situation and doubts that the region engages in “ecotourism.” Coral reef tourism was analyzed with a specific emphasis on tours, tour guides, tourist motivations, tourist education and conservation-related activities. Research methods included participant observation in the tourism world in Bocas, interviews with guides, tourists and community members, and a tourist survey. Though local popular opinion disagrees, data collected shows tourism in Bocas does not emphasize reefs or reef conservation, a potentially catastrophic situation …

Genetic And Spatial Structure Within A Swift Fox Population, Ann M. Kitchen, Eric M. Gese, Lisette P. Waits, Seija M. Karki, Edward R. Schauster

United States Department of Agriculture Wildlife Services: Staff Publications

1. We incorporated spatial data on swift foxes (Vulpes velox) with genetic analysis to assess the influence of relatedness between individuals on their social and spatial ecology. We recorded the space use patterns of 188 radio-collared swift foxes in southeastern Colorado from January 1997 to December 2000. One hundred and sixty-seven foxes were also genotyped at 11 microsatellite DNA loci and the degree of relatedness between individuals was estimated.

2. We described the genetic structure of the population by examining the relatedness of neighbors and the relationship between the spatial and genetic distance of all individuals. We found …

Analysis Of Per Capita Expenditures Of Suburbanizing Communities In Maine, New England Environmental Finance Center

Economics and Finance

This study analyzes per capita expenditure trends among selected fast-growing Maine towns from 1970-2004. The ten communities studied are termed as “suburbanizing” towns. This term is used to describe towns that over the past 30-40 years have been in the process of transition from rural to suburban – in terms of their population and housing densities, their forms of government, and the services they provide, as well as other characteristics.1 Such towns are of particular interest because they have been absorbing a healthy percentage of the state’s population growth during this time period, often at the expense of Maine’s service …

Guide To Nebraska’S Wetlands And Their Conservation Needs: Second Edition, 2005, Ted Lagrange

Nebraska Game and Parks Commission: Publications

Wetlands — a source of great interest, and at times conflict. Wetlands represent different things to different people. At times they’re viewed as shallow, muddy nuisances while at other times they’re viewed as wonderful, varied and productive assets. This is because wetlands take on many roles as part of a complex and dynamic system. Understanding wetlands and wetland issues requires understanding the complex and varying roles that wetlands can play. To aid in this understanding, this guide defines wetlands, discusses their importance and dynamics, identifies threats and losses, describes conservation programs, and takes an in-depth look at Nebraska’s regional wetland …

Final Report: Evaluation Of The Morphoedaphic Index And Sediment Diatoms For Inference Of Pre-European Settlement Total Phosphorus Concentration In Epa Region 10 Lakes, Rich Miller, Aaron Hook, Richard Petersen, Mark D. Sytsma

Center for Lakes and Reservoirs Publications and Presentations

Water quality in many Northwest lakes has declined over the past century due, in part, to increased anthropogenic nutrient loading (Edmonson and Lehman, 1981). Under the Clean Water Act, resource managers such as the Washington Department of Ecology, Oregon Department of Environmental Quality, and tribes are responsible for restoring and protecting the integrity of these waters. Targets for restoration or criteria for impairment are not well defined, however, and may naturally vary by geology, hydrology, morphometry, and climate.

One way to determine whether lakes are impaired and to identify restoration targets is to assess lake reference conditions (EPA 2000). Reference …

Evaluating The Effectiveness Of A Company's Online Health And Safety Training Program By Assessing Its Employees Perceptions And Knowledge., Jo Nell Maynard Mullins

Electronic Theses and Dissertations

A cross-sectional study was conducted to evaluate a company’s online H & S training program. The ABC Company’s online 8-hr HAZWOPER refresher course is based on current OSHA standard topics required for certification and principles flexible to fit site- or task-specific situations and conditions.

An 18-question survey was used to evaluate employee perceptions of online training compared to traditional classroom training. Perceptions were compared by demographic variables (e.g. gender, position, race, age and longevity with the ABC Company), which suggested that only age had an influence on employee response. Fifty-five percent of the employees surveyed preferred online training as compared …

Capsicum Oleoresin: Development Of An In-Soil Repellent For Pocket Gophers, Ray T. Sterner, Stephen A. Shumacke, Stanley E. Gaddis, Jean B. Bourassa

United States Department of Agriculture Wildlife Services: Staff Publications

A pre- and post-monitoring study was conducted of the potential use of capsicum oleoresin as an in-soil repellent for northern pocket gophers (Thomomys talpoides). Pocket gophers were captured in irrigated alfalfa (Medicago sativa L), affixed with radio transmitters, and monitored daily for location. Six plots (4.87 × 4.87m) each were randomly assigned to capsicum oleoresin and soybean oil treatments; these were set up based upon the centers of initial core areas of gophers. Mean (±SD) volumes of capsicum oleoresin and water and soybean oil and water mixtures (10 + 90 by volume) dispensed onto plots equaled 178.5 (±4.7) and 175.7 …

Analyses Of High Resolution Hyperspectral Imagery For Characterization Of Ponderosa Pine Woodlands, Cullen R. Robbins

School of Natural Resources: Dissertations, Theses, and Student Research

The Bessey Unit of the Nebraska National Forest is a planted ponderosa pine forest located in the Nebraska Sand Hills. Planted in the early 20th Century, it provides a unique opportunity to study the effects of ponderosa pine establishment on the surrounding grassland ecosystem and the effects of increasing pine density on the forest ecosystem. It has been hypothesized that there are key levels of canopy cover at which shifts in ecosystem function occur. The goal of this research was to use remotely sensed data to develop a reliable method for estimating canopy cover. More specifically, canopy cover was estimated …

Street Trees In The Urban Forest Canopy: Portland, Oregon, Joseph Poracsky, David Banis

Geography Faculty Publications and Presentations

Attempts to identify the contribution of street trees to the overall urban forest of a city have been rare and lack consensus on how to measure that contribution – percentage of trees, percentage of canopy cover, or percentage of leaf area. The actual numeric values presented in the literature also vary over a broad range and often are based on estimates, extrapolations from aggregated data, or simply stated with no empirical data referenced. This study was undertaken to evaluate the contribution of street trees to canopy in Portland, Oregon. The study involved both visual and digital analysis of multi-band aerial …

Diagnosing And Ameliorating Problem Soils : Decision Tree On How To Diagnose And Ameliorate Problem Soils, Department Of Agriculture And Food, Western Australia

Agriculture reports

Most cropping paddocks in Western Australia have lower yielding areas within paddocks that perform poorly in most years. If the agronomy and management are good, the poor yields are usually due to soil-related problems. Some of these problems can be corrected or reduced by adopting certain proven practices. However, it is important to identify and quantify the problem so that decisions can be made on whether amelioration is possible and economically feasible. The objective is to provide a simploe decision tool for farmers and advisers to use in identifying and quantifying soil problems in agricultural soils in Western Australia. It …

Selective Breeding For High Endurance Running Increases Hindlimb Symmetry, Theodore Garland Jr., Patricia W. Freeman

School of Natural Resources: Faculty Publications

Comparative studies provide correlational evidence of morphological adaptations for high locomotor performance, such as the classical indicators of cursoriality in mammals, long limbs and high metatarsal/femur ratios. More recently, enlarged femoral condyles have been suggested as an adaptation for high endurance running in the genus Homo. Asymmetry of locomotor appendages should adversely affect locomotor abilities, but this has not been studied in a rigorous evolutionary context. We used experimental evolution to test for morphological adaptations associated with high voluntary wheel running in selectively bred lines of mice. Surprisingly, the classical indicators of cursoriality had not evolved in concert with …

High Speed Flight At Low Altitude: Hazard To Commercial Aviation ?, Paul F. Eschenfelder , Capt.

Bird Strike Committee-USA/Canada Joint Annual Meeting: 7th (2005)

Commercial aircraft are capable of, and in fact, do, operate at high speed (>250 knots indicated airspeed [KIAS]) at low altitude (below 10,000’ above ground level) worldwide. Design, construction and certification standards for these aircraft were developed over 40 years ago. Since the development of these standards populations of large flocking birds have increased dramatically in many parts of the world. Yet neither design/construction standards nor operational practice have changed to reflect the new threat. Subsequent serious damage resulting from recent collisions indicates change is necessary. Since 2003, flight rules in Canada and the United States have been amended, …

The July 2003 Dakota Hailswaths: Creation, Characteristics, And Possible Impacts, Matthew D. Parker, Ian Ratcliffe, Geoffrey M. Henebry

School of Natural Resources: Faculty Publications

The authors investigate the meteorology associated with two elongated swaths of crop damage produced by severe hailstorms that crossed North Dakota and South Dakota on 4 July and 20 July 2003. These hailswaths, which were observed in a Moderate Resolution Imaging Spectroradiometer (MODIS) Normalized Difference Vegetation Index (NDVI) image time series, each persisted for more than a month and were associated with local temperature increases, presumably owing to the enhanced Bowen ratio over dry, crop-free ground. This paper documents the creation and evolution of the convective storms that produced the hailswaths, and then presents evidence that devegetated hailswaths may impact …
