An Ecological Assessment Of Wetland Mitigation Projects In East Tennessee, Kim Pilarski

Masters Theses

Federal wetland protection regulations stipulate that developers who destroy natural wetlands are required to construct mitigation or replacement wetlands. Despite the frequency of wetland mitigation, few studies have evaluated the ability of mitigated wetlands to mimic the ecological function and community composition of natural wetlands. Fewer still compare mitigation sites with existing natural wetlands in the same ecological region.

Studies from other freshwater habitats suggest that comparisons of the ratios of functional feeding groups (FFGs) of benthic macroinvertebrates (i.e., shredders, scrapers, collectors, predators) may provide useful information about the ability of mitigated wetlands to mimic the ecological functions of natural …

Relationships Between Selected Environmental Characteristics, Neighborhood Type, And School Achievement, Franklin Titus Iii

Student Work

The primary purpose of this study was to determine if neighborhood and school type help to predict 4th and 6th grade academic achievement above and beyond traditional socioeconomic status (SES) indices. A second purpose was to determine whether the findings of environmental effects research for smaller-size cities differ from studies which investigate larger urban centers. The study also sought to identify potential ways neighborhoods could be meaningfully classified in ways that might aid future research, and the possible presence of schools that succeed despite a profile that says they should not. Achievement test results of schools (N=61) from two Midwest …

Utilization Of Half-Log Structures As Spawning Sites For Smallmouth Bass In Norris Reservoir, Tennessee, Keith A. Patrick

Masters Theses

SCUBA observations were used to evaluate the utilization of half-logs by naturally spawning smallmouth bass (Micropterus dolomieu). Of the 736 half-logs which were installed in Norris Reservoir in 1993, 22% of the total (161) logs were evaluated weekly at three different sites from 2 April 1996 and continuing through 25 June 1996. There were 88 line-transects, each 12.2 m in length, used as controls and positioned in non-structure areas; the transects were located at the same water depths as the half-log structures.

Species found utilizing the half-logs for spawning were smallmouth bass, bluegill (Lepomis macrochirus), black …

Revitalizing Environmental Federalism, Daniel C. Esty

Michigan Law Review

Politicians from Speaker Newt Gingrich to President Bill Clinton, cheered on by academics such as Richard Revesz, are eagerly seeking to return authority over environmental regulation to the states. In the European Union, localist opponents of environmental decisionmaking in Brussels rally under the banner of "subsidiarity." And in debates over international trade liberalization, demands abound for the protection of "national sovereignty" in environmental regulation. All of these efforts presume that a decentralized approach to environmental policy will yield better results than more centralized programs. This presumption is misguided. While the character of some environmental concerns warrants a preference for local …

The Relationship Of Crime Patterns To Social And Ecological Conditions In Grand Rapids, Michigan: 1980-1990, Christine L. Mcgavin

Masters Theses

The spatial distribution of the relationship between crime rates and urban ecology in Grand Rapids, Michigan over time is the focus of this study. Urban ecology can often be measured by indicators of social disorganization. Five crimes (larceny, burglary, robbery, aggravated assault, and homicide) were regressed with several indicators of social disorganization. The independent variables were poverty, transience, family disorganization, the percentage of youth in the population, race, and household density. Both violent and property crimes were strongly related to race while specific crimes were related to poverty, family disorganization, the percentage of youth in the population, and transience. Property …

Helminths Of The Southwestern Toad, Bufo Microscaphus, Woodhouse's Toad, Bufo Woodhousii (Bufonidae), And Their Hybrids From Central Arizona, Stephen R. Goldberg, Charles R. Bursey, Keith B. Malmos, Brian K. Sullivan, Hay Cheam

Great Basin Naturalist

The gastrointestinal tracts, lungs, and urinary bladders from 77 Bufo microscaphus, 61 Bufo woodhousii, and 8 of their hybrids were examined for helminths. One species of trematode (Glypthelmins quieta), 1 species of cestode (Distoichometra bufonis), and 5 species of nematodes (Aplectana incerta, A. itzocanensis, Rhabdias americanus, Physaloptera sp., and Physocephalus sp.) were found. The greatest prevalence (41%) and mean intensity (231.7) were recorded for Aplectana incerta in Bufo woodhousii. It appears hybrids harbor fewer parasites than either parent species.

The Influence Of Landcover Change On Global Terrestrial Biogeochemistry, Steven W. Running, Ramakrishna R. Nemani, Kathy Hibbard, Galina Churkina

Numerical Terradynamic Simulation Group Publications

Discussions concerning global change typically concentrate on future climatic changes promulgated by changes in atmospheric chemistry, most notably increases in the so-called greenhouse gases such as CO2, CH4, and and N2O. Although the energy exchange characteristics of the Earth’s surface are an important component of climate models, the idea that changes in the terrestrial surface could also be a causal factor in climatic changes has not received much attention. Sensitivity studies with GCM’s suggested that regional climate can be dramatically changed by severe deforestation. Dickinson and Henderson-Sellers (1988) simulated the Amazon basin with complete forest cover, and then replaced with …

Directory Of Water Related Courses Offered At Colleges And Universites In Arkansas, Kenneth F. Steele

Technical Reports

This publication lists the water and water-related courses at several universities and colleges in Arkansas as reported during the Fall of 1996. It Is anticipated that users of this directory will extend beyond college students, and will include professionals seeking continuing education, and professors desiring to exchange information on courses. This directory is not an "absolute" source of water and water-related courses because all of the higher learning institutions in Arkansas are not listed, and, secondly, because the definition of "water and water-related" varies from institution to institution. None-the-less this directory provides a very valuable and impressive reference on water …

Eco-Industrial Parks: A Case Study And Analysis Of Economic, Environmental, Technical, And Regulatory Issues, Sheila A. Martin, Keith A. Weitz, Robert A. Cushman, Aarti Sharma, Richard C. Lindrooth, Stephen R. Moran

Institute of Portland Metropolitan Studies Publications

Despite a growing interest in and awareness of applications of industrial ecology (IE), such as eco-industrial parks (EIPs), little information is available about the potential economic and environmental benefits of EIPs, the process for successful EIP development, the important regulatory issues surrounding EIPs, or the technologies needed to support them. This report contains the results of a body of research intended to investigate and support the development of EIPs—communities of companies modeled after industrial ecosystems. EIPs can exist within defined boundaries and broader industrial ecosystems in a region. These communities consciously collaborate to enhance their economic performance through improved environmental …

The Centipede Lithobius Celer (Chilopoda: Lithobiidae) In Wisconsin, Dreux J. Watermolen

Field Station Bulletins

The centipede Lithobius celer Bollman 1888 has been reported from Wisconsin only one time. Chamberlin (1911) provisionally referred specimens collected from unspecified Wisconsin and Michigan localities to this species, with considerable doubt since neither was a ''fully-grown male/' Subsequent investigators (e.g., Matthews 1935, Crabill 1958) did not report L. celer from the state. While examining specimens collected as part of an on-going prairie ecology study, I discovered a L. celer specimen from southern Wisconsin. The specimen was collected in a pitfall trap at Hawkhill Prairie, Dane County (T9N, R8E, Sec. 5) on 21 August 1986 by A. Lisken.

Preserving Dynamic Systems: Wetlands, Ecology And Law, Alyson C. Flournoy

UF Law Faculty Publications

Ecology has advanced human understanding of natural systems considerably over the course of this century. Wetlands law and policy have evolved in response to our increased understanding of wetlands and the many benefits we derive from them. Notwithstanding this shift in policy and law, roughly 50% of the wetlands that existed in the continental United States in colonial times have been lost or degraded largely as a result of recent human activity. Current policies struggle to reconcile the goal of preventing further loss with the pervasive concern for making our laws more efficient.

This essay explores the lessons ecology offers …

The Diet Of Oryzomys Palustris Based On Stomach Content Analysis, Shannon L. Wright

Biological Sciences Theses & Dissertations

Oryzomys palustris (Harlan) is unusual in that it is one of two carnivorous mammals in the Family Muridae in North America. A diet analysis of Oryzomys palustris. the marsh rice rat, was done based on stomach contents. This was accomplished by taking the animals from two study areas located on the Eastern Shore of Virginia. The animals were taken monthly for one year. Once caught, the animals were sacrificed and their stomach contents were identified to the lowest taxonomic level possible. This study showed that rice rats were omnivorous mammals, eating a variety of foods, including dicots, monocots, crabs, …

Research Needs For The Risk Assessment Of Health And Environmental Effects Of Endocrine Disruptors: A Report Of The Us Epa-Sponsored Workshop, Rj Kavlock, Gp Daston, C Derosa, P Fennercrisp, Le Gray, S Kaattari, Et Al

VIMS Articles

The hypothesis has been put forward that humans and wildlife species have suffered adverse health effects after exposure to endocrine-disrupting chemicals. Reported adverse effects include declines in populations, increases in cancers, and reduced reproductive function. The U.S. Environmental Protection Agency sponsored a workshop in April 1995 to bring together interested parties in an effort to identify research gaps related to this hypothesis and to establish priorities for future research activities. Approximately 90 invited participants were organized into work groups developed around the principal reported health effects-carcinogenesis, reproductive toxicity, neurotoxicity, and immunotoxicity--as well as along the risk assessment paradigm--hazard identification, dose-response …

The Interactive Effect Of Shade And Drought On Seedling Growth And Survival, Milena Holmgren

Doctoral Dissertations

The hypothesis that plants face a trade-off between shade and drought tolerance is examined. Smith and Huston (1989) had used the trade-off model to predict the growth and survival of different plant functional types along gradients of light and water availability, and showed that several natural patterns of plant distribution and succession could, in principle, be explained from this hypothesized response-model. Based on a set of assumptions on plant morphological and physiological responses to drought and shade, the authors had predicted that under drier conditions plants would become less shade tolerant, and, therefore, would grow and survive better under higher …

The Flora And Ecology Of Seidman Park, Kent County, Michigan, Pamela J. Laureto

Masters Theses

A floristic study of Seidman Park, Kent County, Michigan was performed. The study identified 521 vascular plants belonging to 96 families and 284 genera. The plant communities of Seidman Park were delimited by identification of dominant species and observation of the physical environment. It was believed that communities existed within the upland forest that could not be identified by observation alone. The use of Non-Metric Multidimensional Scaling (NMS) ordination techniques identified three communities within the upland forest. These were a xeric community, a dry-mesic community and a nutrient-rich community. Three sub-communities of the dry-mesic community were also identified.

Arkansas Rice Research Studies 1995, R. J. Norman, B. R. Wells

Arkansas Agricultural Experiment Station Research Series

The research reports in this publication represent one year of results; therefore, these results should not be used as a basis for long-term recommendations. Several research reports in this publication dealing with soil fertility also appear in Arkansas Soil Fertility Studies 1995 , Arkansas Agricultural Experiment Station Research Series 450. This duplication is the result of the overlap in research coverage between the two series and our effort to inform Arkansas rice producers of all the research being conducted with funds from the rice check-off. Use of products and trade names in any of the research reports of this publication …

Impact Of A Parasitic Plant On The Structure And Dynamics Of Salt Marsh Vegetation, Steven C. Pennings, Ragan M. Callaway

Biological Sciences Faculty Publications

We investigated the effect of a native parasitic plant, Cuscuta salina, on the structure and dynamics of the plant community in a California salt marsh. Cuscuta was common in the middle marsh zones. The abundance of Cuscuta was positively correlated with the abundance of Limonium californicum at two sampling scales (0.25— and ≈\approx40—m² quadrats). Sampling at the scale of individual plants indicated that the dominant plant in the marsh, Salicornia virginica, was preferred by Cuscuta as a host over Arthrocnemum subterminale, Limonium californicum, and Frankenia salina. This result was confirmed with host—choice experiments in the field. Based on spatial …

Temperature-Driven Variation In Substrate Oxygenation And The Balance Of Competition And Facilitation, Ragan M. Callaway, Leah King

Biological Sciences Faculty Publications

Emergent wetland plants often alleviate the effects of anaerobic soils on root respiration by passively transporting oxygen belowground through continuous air spaces (aerenchyma) in leaves and roots. Oxygen leaked from the roots into the rhizosphere may oxidize minerals in the soil or become available to other plants. Some spatial patterns in marsh plant communities suggest interspecific facilitative interactions, but there is little experimental evidence for interplant facilitation via soil oxygenation. We investigated the capability of the widespread, highly aerenchymous wetland plant, Typa latifolia, to aerate sediments and affect the growth of two non—aerenchymous neighbors, Salix exigua and Myosotis laxa, both …

Premature Mortality From Chronic Diseases In Brazil. [Portuguese], Paulo A. Lotufo

Paulo A Lotufo

This thesis evaluated the pattern of chronic diaseases mortality in Brazil during the 1980´s. We studied the age strata from 35-years-old to 64-years-old to analyze the chronic disease-related premature deaths. The questions are the following: 1. Are chronic disease-related premature deaths higher in Brazil than abroad? 2. Is premature mortality higher in males than in females? Which is the best indicator for premature mortality, age-adjusted rates or the impact of deaths elimination by Chiang’ method? Are there geographic or temporal differences in chronic diseases mortality rates among Brazilian metropolitan areas? 5. Which are the social and economics determinants of chronic …

Effects Of Predator Reduction On The Survival And Movements Of Northern Shoveler Broods, John M. Zimmer

LSU Historical Dissertations and Theses

I studied the effects of predator removal on survival and movements of Northern Shoveler (Anas clypeata) broods in the prairie pothole region of North Dakota. The study was conducted from April through August 1995. No treatment effects were found on brood survival as both 14 and 30 day survival estimates were statistically equivalent. Experimental sites had higher brood and duckling survival and produced twice as many fledglings per successful nest than control sites. Cumulative movement distance had no effect on duckling survival. While survival rates of Northern Shoveler broods and ducklings were higher than most species of prairie nesting ducks, …
