Rare And Endangered Plants At Gateway National Recreation Area: A Case For Protection Of Urban Natural Areas, Richard Stalter, Michael D. Byer, John T. Tanacredi Ph.D. Jul 1996

Rare And Endangered Plants At Gateway National Recreation Area: A Case For Protection Of Urban Natural Areas, Richard Stalter, Michael D. Byer, John T. Tanacredi Ph.D.

Faculty Works: CERCOM

The diversity of native plant species in urban environments is usually overlooked when biodiversity levels are considered. Inventories of native plants reveal many to be rare species surviving the harsh conditions encountered in urban ecosystems. Knowledge of their existence and an inventory of their distribution will assist in maintaining these populations. Protection strategies for rare plant species are outlined for urban National Parks.

Agenda: Biodiversity Protection: Implementation And Reform Of The Endangered Species Act, University Of Colorado Boulder. Natural Resources Law Center

Biodiversity Protection: Implementation and Reform of the Endangered Species Act (Summer Conference, June 9-12)

Conference organizers and/or faculty included University of Colorado School of Law professors Betsy Rieke, David H. Getches, Michael A. Gheleta and Charles F. Wilkinson.

All across the country--in Congress, in state legislatures and in urban and rural communities--people are discussing why we should or should not protect biodiversity and how best to do so. Since the Endangered Species Act is up for reauthorization, a variety of reform proposals are being debated. Speakers--including natural resource scholars, experts from the private and nonprofit sectors, and government officials--will examine the rationale for biodiversity protection, the legal framework of the Endangered Species Act, and …


Habitat Selection And Movement Of A Stream-Resident Salmonid In A Regulated River And Tests Of Four Bioenergetic Optimization Models, Mark D. Bowen May 1996

Habitat Selection And Movement Of A Stream-Resident Salmonid In A Regulated River And Tests Of Four Bioenergetic Optimization Models, Mark D. Bowen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A bioenergetics model was constructed for stream-resident drift-feeding salmonids. Model predictions of surplus power (energy available per unit time for growth and reproduction) were not statistically distinguishable from observations of surplus power in three laboratory studies. Of 40 experimental trials in these three studies, the model correctly predicted surplus power in 39 cases (p < 0.05).

I collected observations of rainbow trout (Oncorhynchus mykiss) focal velocity and physical habitat availability in the Green River of northeastern Utah, USA (1988-1990). In the winter of 1988, Flaming Gorge Dam generated hydropower and delivered an lJDStable discharge regime with a higher mean discharge …


Recruitment Of Blue Crab, Callinectes Sapidus, Postlarvae To The Back-Barrier Lagoons Of Virginia's Eastern Shore, Robert D. Brumbaugh Apr 1996

Recruitment Of Blue Crab, Callinectes Sapidus, Postlarvae To The Back-Barrier Lagoons Of Virginia's Eastern Shore, Robert D. Brumbaugh

OES Theses and Dissertations

Most research on the early life history of the blue crab, Callinectes sapidus, has been conducted in large partially stratified estuaries such as the Chesapeake Bay. In contrast, little is known about the recruitment dynamics or habitat requirements of blue crab postlarvae (megalopae) in shallow well-mixed lagoonal systems that make up a considerable part of the species' range. In Virginia's coastal lagoons, planktonic blue crab megalopae are most abundant at night on flooding tides, and are not abundant during the daytime or on ebbing tides. This appears to enhance retention within the lagoons, despite the short residence time of water …


The Evolution Of International Fisheries Management In The North Pacific Ocean And Prospects For The Future, Paul Augustus Flynn Jan 1996

The Evolution Of International Fisheries Management In The North Pacific Ocean And Prospects For The Future, Paul Augustus Flynn

Theses and Major Papers

The abundant resources of the North Pacific Ocean have been the subject of international disputes and negotiations through the 20th century. The management of species which range throughout this vast area, are not under the jurisdiction of a single state. That fact has required the establishment of a framework in which allocation and conservation measures can be researched and agreed upon. This has been accomplished through various multilateral and bilateral agreements. From the voluntary Japanese suspension of a directed salmon fishery off the coast of Alaska in 1938 to recently completed multilateral treaties, significant advances have been made in Pacific …


International Organizations And Tuna Management; Problems And Future Prospects, Yuh-Chen Chern Jan 1996

International Organizations And Tuna Management; Problems And Future Prospects, Yuh-Chen Chern

Theses and Major Papers

A large number of marine species migrate within and without national jurisdictions and a small number occur entirely outside any national jurisdiction. Thus, the species migrating through waters under the jurisdiction of coastal states to high seas beyond the jurisdiction of any single state are defined as highly migratory species (HMS). International organizations play a key role in the management of highly migratory species. Most of the international organizations concerned with HMS focus on tuna management.


Sacrificing Conservation For Pesos: An Analysis Of Select Marine Fisheries In The Political Environment Of Mexico, Sephen W. Bourgeois Jr. Jan 1996

Sacrificing Conservation For Pesos: An Analysis Of Select Marine Fisheries In The Political Environment Of Mexico, Sephen W. Bourgeois Jr.

Theses and Major Papers

The decline of most Mexican fisheries has occurred so rapidly that few Mexicans and Americans alike fully appreciate the loss. The major focus of this paper will examine the false impression that Mexico is engaging in marine conservation; in reality, its conservation efforts are responses to after-the-fact actions brought on by world critics and as a vehicle to pacify conservationists. The Mexican government can pass a law but lacks the resources to administer and enforce the law and subsequently manage its fisheries in an effective manner. Rather than survey the state of every fishery found in Mexican waters, this paper …


Trends In Abundance Of The Gulf Of Maine Population Of Harbor Porpoise, Paula Ann Olson Jan 1996

Trends In Abundance Of The Gulf Of Maine Population Of Harbor Porpoise, Paula Ann Olson

Theses and Major Papers

Hundreds of harbor porpoise die each year as bycatch in the Gulf of Maine's sink gillnet fishery. In recent years, concern has arisen whether the Gulf of Maine population of harbor porpoise can sustain this level of bycatch. It is believed that the population may have declined, or is declining as a result of the incidental moralities. This paper reviews what is known about Gulf of Maine harbor porpoise demographics and how that information is incorporated into the management of the porpoise/fishery interaction. Included in this paper is a new study on the trend of relative abundance of harbor porpoise …


Protection Of Marine Fish Habitat: Towards An Integrated Approach To Management, Andrea L. Oliver Jan 1996

Protection Of Marine Fish Habitat: Towards An Integrated Approach To Management, Andrea L. Oliver

Theses and Major Papers

This paper focuses on the problems associated with marine fish habitat protection and conservation at the federal level in the United States. The intent of the study is to provide a general overview of the issues, impacts, management problems and potential solutions. Federal statutory legislation that impacts marine fish habitat and agency authority derived from those legislative mandates are examined with a view toward promoting integrated management for marine biodiversity and overall ecosystem health. The concepts of coordinated and integrated approaches to management are discussed in the context of the present management regimes. Given the fragmented authority over the policy …


Limits To Private Aquaculture On Cape Cod, Kevin Robert Cute Jan 1996

Limits To Private Aquaculture On Cape Cod, Kevin Robert Cute

Theses and Major Papers

This study examined the potential of social conflict related to private and public rights, to constrain aquaculture on Cape Cod. While the ability of social conflict to constrain aquaculture has been demonstrated in a few cases, its current potential to constrain aquaculture on Cape Cod had not been established prior to this study. This study was based on information gathered from town records and public hearings related to proposed aquaculture ventures. In addition, town officials were interviewed to obtain additional information related to cases. The finding of this study is that private riparian proprietors, and interests in shell-fishing tend to …


The Role Of The Federal Aid In Sportfish Restoration Program In Promoting State Marine Artificial Reef Development Activities, Loren Clark Evans Jan 1996

The Role Of The Federal Aid In Sportfish Restoration Program In Promoting State Marine Artificial Reef Development Activities, Loren Clark Evans

Theses and Major Papers

The passage of the Wallop-Breaux Amendments to the Federal Aid in Sportfish Restoration Program (FASRP), in 1984, significantly increased the funding available to states participating in the Program. Subsequently, the FASRP became the largest single source of funding for state marine artificial reef development activities. In recent years, there has been concern among program constituents that FASRP funds are not being utilized as intended. The principle question of the current research focused on how effective FASRP subsidies have been in providing meaningful benefits to state fisheries management programs. Specifically, the research focused on the application of FASRP monies in promoting …


Public Health Hazards Associated With The Consumption Of Molluscan Shellfish In The State Of Rhode Island, Jeffrey F. Nussbaum Jan 1996

Public Health Hazards Associated With The Consumption Of Molluscan Shellfish In The State Of Rhode Island, Jeffrey F. Nussbaum

Theses and Major Papers

The principal objective of this thesis was to descriptively and empirically assess shellfish consumption hazards in the state of Rhode Island and to evaluate the use of a shellfish hazard warning label to modify unsafe consumptive behaviors. To accomplish this task, three research problems were examined using a survey instrument. The survey instrument was a questionnaire which included both closed and open-ended questions. The survey questions were designed to identify four primary research variables; shellfish consumptive behaviors, consumer knowledge of shellfish hazards and related government advisories, perceptions of risk regarding personal shellfish consumption, and response to warning label information. The …

Effects Of Daphnia Availability On Growth And Food Consumption Of Rainbow Trout In Two Utah Reservoirs, R. Tabor, Chris Luecke, Wayne A. Wurtsbaugh Jan 1996

Effects Of Daphnia Availability On Growth And Food Consumption Of Rainbow Trout In Two Utah Reservoirs, R. Tabor, Chris Luecke, Wayne A. Wurtsbaugh

Watershed Sciences Faculty Publications

We monitored the diet and growth of stocked rainbow trout Oncorhynchus mykiss in two Utah reservoirs during 1986 and 1989–1990. For the first month after stocking, juvenile rainbow trout in both reservoirs fed extensively on large Daphnia spp. In East Canyon Reservoir where Daphnia were abundant, this pattern continued throughout the summer, fall, and winter. Growth of rainbow trout in East Canyon Reservoir was generally good throughout 1989–1990. In Causey Reservoir, where Daphnia were less abundant and smaller, rainbow trout fed progressively less on smaller Daphnia throughout the summer, fall, and winter, while other prey items (snails, aquatic insects, and …


Simulated Growth And Production Of Endangered Snake River Sockeye Salmon: Assessing Management Strategies For The Nursery Lakes, Chris Luecke, Wayne A. Wurtsbaugh, Phaedra E. Budy, H. P. Gross Jan 1996

Simulated Growth And Production Of Endangered Snake River Sockeye Salmon: Assessing Management Strategies For The Nursery Lakes, Chris Luecke, Wayne A. Wurtsbaugh, Phaedra E. Budy, H. P. Gross

Watershed Sciences Faculty Publications

We examined the potential of employing a series of lake management strategies to enhance production of endangered Snake River sockeye salmon (Oncorhynchus nerka) in its historical nursery lakes in central Idaho. We used a combination of limnological sampling, experimentation, and simulation modeling to assess effects of lake fertilization and kokanee reduction on growth and survival of juvenile sockeye salmon. Juvenile sockeye salmon from a broodstock of this endangered species are being introduced into the lakes from 1995 to 1998. Results of our analyses indicated that several lakes were suitable for receiving broodstock progeny. Field experimentation and simulation modeling indicated that …
