Governmental regulation for environmental protection and other important public purposes can affect the manner in which land and natural resources are developed and used. The U.S. constitution (and most state constitutions) prohibit the government from "taking" property without payment of compensation. Originally intended to apply to situations where the government physically seized private property …

Dartmouth Scholarship
Genetic characteristics of 14 Rhizobium and 9 Bradyrhizobium mesquite (Prosopis glandulosa)-nodulating strains isolated from surface (0- to 0.5-rn) and deep (4- to 6-m) rooting zones were determined in order to examine the hypothesis that surface- and deep-soil symbiont populations were related but had become genetically distinct during adaptation to contrasting soil conditions. To examine genetic diversity, Southern blots of PstI-digested genomic DNA were sequentially hybridized with the nodDABC region of Rhizobium meliloti, the Klebsiella pneumoniae nifHDK region encoding nitrogenase structural genes, and the chromosome- localized ndvB region ofR. meliloti. Plasmid profile and host plant nodulation assays were also made. Isolates …

A River Ran Through It... : The Cultural Ecology Of The Santa Clara Valley Riparian Zone, Erin M. Reilly
Research Manuscript Series
This study addresses the nature of human interaction with the riparian environment in the Santa Clara Valley over time. This is not a new anthropological theme. Literature dates to 1863 The Earth as Modified by Human Action, by George P. Marsh); cultural ecologist Betty J Meggars stated: "The relationship- of culture to environment is one of the oldest problems in the science of anthropology ... "(Meggars, 1968:19); and, anthropologist Alfred Kroeber said: "no culture is wholly intelligible without reference to the nonculture, or so-called environmental factors with which it is in relation and which condition it "(Kroeber 1906:297).

Predicting The Past, Recounting The Future: Human Ecology And A Prehistory Of Consciousness, Paul Faulstich
Pitzer Faculty Publications and Research
This paper is concerned with the organic derivation and primary meaning of Pleistocene finger flutings; I propose that in order to gain insight into the significance of the flutings, we must attempt an understanding of the physical and mental contexts in which they emerged. I suggest that finger flutings provided a cultural record in the Pleistocene which documented thought and action, and made it ready for reflection. Through the process of finger fluting, the human 'self' was objected and reality was modified in the experience of self-consciuosness. I argue that finger flutings, like language, were employed to discover and convey …

Summer Habitat Use Of Littoral-Zone Fishes In Lake Tahoe And The Effects Of Shoreline Structures, D. Beauchamp, E. Byron, Wayne A. Wurtsbaugh
Summer Habitat Use Of Littoral-Zone Fishes In Lake Tahoe And The Effects Of Shoreline Structures, D. Beauchamp, E. Byron, Wayne A. Wurtsbaugh
Watershed Sciences Faculty Publications
We used scuba observations to determine summer habitat use and the effects of piers on the littoral-zone fish community in Lake Tahoe, California–Nevada. Habitat complexity declined with depth. Over 50% of the littoral zone less than 2 m deep was composed of complex boulder substrates, but this substrate represented less than 10% of the habitat between 10 and 18 m deep. A severe drought lowered the surface elevation of the lake 2 m and reduced the wetted complex rocky habitat by 20% between the 0- and l0-m isobaths (referenced to the mean lake level of 1,899 m above sea level). …

Dietary Comparisons Of Adult Male Common Grackles, Red-Winged Blackbirds, And Yellow-Headed Blackbirds In North Central North Dakota, H. Jeffrey Homan, George M. Linz, William J. Bleier, Robert B. Carlson
United States Department of Agriculture Wildlife Services: Staff Publications
We compared the esophageal contents of adult male common grackles (Quiscalus quiscula), red-winged blackbirds (Agelaius phoeniceus),and yellow-headed blackbirds (Xanthocephalus xanthocephalus) collected in north central North Dakota from July through October 1989. Temporal variation in the diets of all species was related to food availabilities, which were heavily influenced by crop phenology. Depending on species, mean percent dry weight of sunflower achenes during August increased 2-6 times over July. Yellow-headed blackbirds migrated from north central North Dakota by early September, but substantial numbers of common grackles and red-winged blackbirds remained until mid-October. Sunflower was an …
Application Of Time Series Models To Sets Of Environmental Data, Saarah Ahmed Farag
Application Of Time Series Models To Sets Of Environmental Data, Saarah Ahmed Farag
Theses : Honours
In environmental studies, many programs have been implemented for the purpose of examining the influence of factors on the natural environment from various sources. In the past, predictions have been obtained from a simple regression model of the data from these programs to aid in deciding whether an intervention is required in the program or policy. However, most environmental time series involve correlated dependent variables which makes it difficult to apply conventional regression analysis. This thesis compares the application of the class of transfer function models, where high correlation between dependent variables is allowed, to that of conventional regression analysis. …

Environmental Attitudes And Knowledge: An International Comparison Among Business Students, Raymond Benton Jr., G. Ray Funkhouser
School of Business: Faculty Publications and Other Works
This article investigates international differences in environmental knowledge and attitudes among business administration students. The Environmental Knowledge and Attitude Scale, developed by Maloney, Ward, and Braucht (1975) and used by Synodinos (1990), was administered to 85 upperdivision business administration students at Loyola University Chicago and 111 upperdivision business students at the National University of Singapore. No significant differences were found between the two samples on the Knowledge, Concern, or Willingness to Act subscales. The United States students' higher mean score on the Actual Behavior subscale was significant but may only reflect relative possibilities for participation in environmental activities. Overall, the …

An Ecosystem Approach To Wildlife Management In Wilderness Areas: A Case Study Of The Greater Kluane Region, Lori Katherina Krebs
An Ecosystem Approach To Wildlife Management In Wilderness Areas: A Case Study Of The Greater Kluane Region, Lori Katherina Krebs
Theses and Dissertations (Comprehensive)
This research examines the implications of an ecosystem approach to planning and management for sustainable wildlife populations within a wilderness setting. Kluane National Park Reserve and the surrounding region are the focus of the study, providing a relatively unaltered ecosystem in which to explore certain questions regarding ecosystem-based wildlife management. The ever increasing human population and constant surge of development are placing more and more pressure on remaining natural resources. Wilderness areas and wildlife habitat are disappearing rapidly, and the north is receiving unprecedented activity in the search for remaining resources. Management strategies must be created which will be capable …
Opportunities For Integration In Institutional Arrangements For Water Management In The Yukon, Patrick James Dooling
Opportunities For Integration In Institutional Arrangements For Water Management In The Yukon, Patrick James Dooling
Theses and Dissertations (Comprehensive)
The history of water resources management in the Yukon has been characterized by conflict. This problem is due to the failure to address the interrelationships between water and land resources. Although many parts of the Yukon remain largely undisturbed wilderness areas, development pressures place increasing demands on Territorial water resources. To ensure these stresses do not degrade Yukon waters to the extent common in many Canadian regions, a reevaluation of the legal and administrative arrangements for water management in the Yukon is required. A majority of the legislation pertaining to water management in the Yukon was introduced in the 1970s …

Aquatic Macrophytes Of Two Small Northwest Arkansas Reservoirs, John J. Sullivan, Arthur V. Brown
Aquatic Macrophytes Of Two Small Northwest Arkansas Reservoirs, John J. Sullivan, Arthur V. Brown
Journal of the Arkansas Academy of Science
Lake Fayetteville and Lake Wedington are small reservoirs of about the same size and age that are located in northwestern Arkansas. We collected macrophytes from eleven transects around each reservoir in the autumn of 1993. Justicia (waterwillow), Typha (cat-tail), Scirpus (bulrush), Potamogeton (pondweed), and Zannichellia (horned pondweed) occur in both reservoirs. Justicia occurs most commonly in both reservoirs. The macrophytes of Lake Wedington are organized in a characteristic zonation pattern with bands from shore toward open water of emergent, floating-leaved, then submersed macrophytes. Macrophyte zonation was not as evident in Lake Fayetteville because of the low occurrence of floating leaved …

Analysis And Evaluation Of The Workplace Exposure Assessment Workbook Developed By Keith Tait Including Some Recommended Revisions, Lisa Hebberd
UNLV Theses, Dissertations, Professional Papers, and Capstones
Some risk due to the contamination of workplace environments is an inevitable part of human lives. These risks can often be reduced by improving the control of environmental pollution in the workplace. An extremely important challenge for any industry is to develop a mechanism to identify acceptable levels of safety, or "acceptable risk" in the workplace for specific situations, and to assure adequate quality control over measured or calculated exposure concentrations and their possible contributions to adverse health effects.

Sections 307 and 309 of the 1988 Indoor Radon Abatement Act (IRAA) direct EPA to identify areas of the United States that have the potential to produce elevated levels of radon. EPA, the U.S. Geological Survey (USGS), and the Association of, American State Geologists (AASG) have worked closely over the past several years to produce a series of maps and documents which address these directives. The EPA Map of Radon Zones is a compilation of that work and fulfills the requirements of sections 307 and 309 of IRAA. The Map of Radon Zones identifies, on a county-by-county basis, areas of …

Paleocene To Miocene Foraminifera From A Well Near Gloucester, Virginia, Nelson Stanley Ford
Paleocene To Miocene Foraminifera From A Well Near Gloucester, Virginia, Nelson Stanley Ford
OES Theses and Dissertations
Lithologic analysis of twenty-one core samples from a well near Gloucester, Virginia, when compared to published descriptions of formations occurring in the study area, indicates the presence of five formations. From oldest to youngest these units are the Aquia (late Paleocene), Nanjemoy (early Eocene), Chickahominy (late Eocene), Old Church (late Oligocene and early Miocene), and Eastover (late Miocene) formations. Comparison of the stratigraphic ranges of key planktic and benthic foraminifera from each of the core samples shows chronological agreement with previously published ages for each of these formations.
Paleoenvironmental analysis of each of the formations in the well is based …
Design And Performance Evaluation Of A Gas Chromatograph Micromachined In A Single Crystal Silicon Substrate, Rocky R. Reston
Design And Performance Evaluation Of A Gas Chromatograph Micromachined In A Single Crystal Silicon Substrate, Rocky R. Reston
Theses and Dissertations
This investigation designed and developed a miniature gas chromatograph (GC) using silicon micromachining techniques. The GC is composed of a miniature sample injector (10 µl sample loop); a 0.9 m long, rectangular-shaped (300 µm width and 10 micrometers height) capillary column coated with a 0.2 µm thick copper phthalocyanine (CuPc) stationary phase; and a dual-detector scheme incorporating a CuPc-coated chemiresistor and a 125 µm diameter thermal conductivity detector bead. Micromachining was employed to fabricate the sample injector interface, the GC column, and the dual-detector cavity. A novel processing technique was developed to sublime the CuPc stationary phase coating on the …

Monthly mean maximum and minimum temperatures for over 50% (10%) of the Northern (Southern) Hemisphere landmass, accounting for 37% of the global landmass, indicate that the rise of the minimum temperature has occurred at a rate three times that of the maximum temperature during the period 1951-90 (0.84°C versus 0.28°C). The decrease of the diumal temperature range is approximately equal to the increase of mean temperature. The asymmetry is detectable in all seasons and in most of the regions studied.
