Seasonal Proximate Composition And Food Source Comparisons Of Dolly Varden Char In The Kugururok River, Alaska, Robert James Foy Dec 1996

Seasonal Proximate Composition And Food Source Comparisons Of Dolly Varden Char In The Kugururok River, Alaska, Robert James Foy

Fisheries

The Kugururok River on the Noatak River System is an important spawning tributary for Dolly Varden char (Salvelinus malma), an important subsistence resource, occur bycatch in commercial fisheries, and are the basis of a sport fishery. The feeding habits and energetic condition of two spawning run patterns in the Noatak River Drainage were studied. Isotope ratio analysis revealed a predominantly marine carbon and nitrogen composition in all adult char. No internal isotopic fractionations were found either between tissues or seasons in any tissue. Proximate analysis revealed patterns of lipid and protein utilization characteristic of periodic starvation in fishes. Significant shifts …

The Relationship Of Crime Patterns To Social And Ecological Conditions In Grand Rapids, Michigan: 1980-1990, Christine L. Mcgavin Dec 1996

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 …

Revitalizing Environmental Federalism, Daniel C. Esty Dec 1996

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 …

Relationships Between Selected Environmental Characteristics, Neighborhood Type, And School Achievement, Franklin Titus Iii Dec 1996

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 …

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 Nov 1996

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.

Directory Of Water Related Courses Offered At Colleges And Universites In Arkansas, Kenneth F. Steele Nov 1996

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

Arkansas Water Resources Center 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 …

The Influence Of Landcover Change On Global Terrestrial Biogeochemistry, Steven W. Running, Ramakrishna R. Nemani, Kathy Hibbard, Galina Churkina Nov 1996

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 …

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 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 …

Preserving Dynamic Systems: Wetlands, Ecology And Law, Alyson C. Flournoy Oct 1996

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 Oct 1996

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, …

The Flora And Ecology Of Seidman Park, Kent County, Michigan, Pamela J. Laureto Aug 1996

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.

Impact Of A Parasitic Plant On The Structure And Dynamics Of Salt Marsh Vegetation, Steven C. Pennings, Ragan M. Callaway Jul 1996

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 Jun 1996

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 …

Summer Habitat Relationships And Foraging Ecology Of The Delta Bison Herd, Maria Berger May 1996

Summer Habitat Relationships And Foraging Ecology Of The Delta Bison Herd, Maria Berger

Biological Sciences

Investigations of habitat use, diet composition and diet selection of introduced plains bison (Bison bison bison) in interior Alaska in summer were conducted during 1989 through 1991. Bison used early- and mid-successional plant communities on the floodplain of the Delta River and wetlands above the floodplain. Grasses predominated in summer diets of bison, but substantial amounts of willow (Saiix) were included. Other shrubs were used much less than available, as were sedges. The role of sedges in bison diets may be changing as bison increasingly have exploited sedge-dominated wetland habitats. Experimental studies of the effects of bison grazing on forage …

Effects Of Predator Reduction On The Survival And Movements Of Northern Shoveler Broods, John M. Zimmer May 1996

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, …
