Comparison Of Dietary Overlap Between Allopatric And Sympatric Geckos, Paul D. Klawinski, R. Kathryn Vaughan, Daniel Saenz, William Godwin
Faculty Publications
Two gecko species, Hemidactylus turcicus and Cyrtopodion scabrum, have been introduced into the Port of Galveston, Texas. While H. turcicus has been established for a longer period of time, the relatively recent introduction of C. scabrum near the entrance of the Port has apparently led to the displacement of H. turcicus in that area. This has resulted in a distribution in which the two populations’ are largely allopatric except for a narrow band of sympatry at the periphery of each of their ranges. We examined stomach contents of both species in allopatry and sympatry in order to determine if …
Predicting Modes Of Toxic Action From Chemical Structure: An Overview, Steven P. Bradbury
Predicting Modes Of Toxic Action From Chemical Structure: An Overview, Steven P. Bradbury
Steven P. Bradbury
In the field of environmental toxicology, and especially aquatic toxicology, quantitative structure activity relationships (QSARs) have developed as scientifically-credible tools for predicting the toxicity of chemicals when little or no empirical data are available. A basic and fundamental understanding of toxicological principles has been considered crucial to the continued acceptance and application of these techniques as biologically relevant. As a consequence, there has been an evolution of QSAR development and application from that of a chemical-class perspective to one that is more consistent with assumptions regarding modes of toxic action. The assessment of a compound’s likely mode of toxic action …
Field Identification Of Birdseye In Sugar Maple (Acer Saccharum Marsh.), Douglas D. Stokke, Don C. Bragg
Field Identification Of Birdseye In Sugar Maple (Acer Saccharum Marsh.), Douglas D. Stokke, Don C. Bragg
Douglas D. Stokke
Birdseye grain distortions in sugar maple must be identified to capture the full value of a timber sale throughout the economic range of birdseye's occurrence. Even when relatively common, birdseye veneer typically makes up less than 1 percent of the harvested volume, but may account for one-half of the value of the sale. With prices recently reaching $50,000 per Mbf for prime logs, omission of birdseye (when present) from cruise data could cause significant economic loss for the forest landowner. But figured wood can sometimes be detected in standing timber (Pillow 1955). Field identification of birdseye sugar maple is critical …

Base Realignment And Closure - 93: Impacts On Western Aquidneck Island An Opportunity For Enrichment, Frank W. Garcia Jr.
Marine Affairs Theses and Major Papers
This paper will develop a conceptual Use/Resource model which may be of use in analyzing coastal zone conflicts. The use/Resource model will be applied to provide an outline for a cooperative enrichment plan for Western Aquidneck Island, Rhode Island. Future studies of Western Aquidneck Island or other coastal communities may be able to use the model to quantify the level of Use/Resource cooperation. Heuristic application of the Model along Western Aquidneck may highlight the level of conflict or cooperation in working towards an enrichment plan. The focus of the enrichment plan will be to improve the quality of life in …
The Evolving "Takings" Doctrine: The Supreme Court Poses A Challenge For Coastal Zone Management, Catherine L. Chase
The Evolving "Takings" Doctrine: The Supreme Court Poses A Challenge For Coastal Zone Management, Catherine L. Chase
Marine Affairs Theses and Major Papers
There is an increasingly powerful and vocal group coalescing in society today, sometimes described as anti-environmentalists or Property Firsters, who feel that the government has exceeded its authority in interfering with individual rights for the purpose of protecting natural resources. Regardless of any personal convictions regarding this often emotionally-charged issue, people involved in coastal management and planning should be aware of the changes in legal doctrines which have come about as a result of "property first" challenges to regulatory or zoning statutes. These challenges have been pursued successfully in the courts by characterizing state and local land use ordinances as …
Port Development At Port Canaveral, Florida, Sergio A. Cartaya
Port Development At Port Canaveral, Florida, Sergio A. Cartaya
Marine Affairs Theses and Major Papers
The restrictions and goals influencing port development today, differ from those that prompted development in the very recent past. In the 1960s, innovations in the transport of cargo and passengers drastically changed maritime transport. In the 1970s, a new awareness of the environment demanded, and through the decade implemented, new changes in coastal development. Port development today is no longer a transaction between the port authority and the Army Corps of Engineers, new federal agencies, with strict developmental guidelines, and the general public are now involved. The outcome of this new way of doing business has been that the lead-time …
State Imposed Anchorage Laws: Legitimate Practice, Or Unconstitutional Restriction Of Navigation?, George Yatrakis
State Imposed Anchorage Laws: Legitimate Practice, Or Unconstitutional Restriction Of Navigation?, George Yatrakis
Marine Affairs Theses and Major Papers
In recent times, there has been a proliferation of laws enacted by individual states and townships which restrict the ability of mariners to anchor within navigable waters of the United States. These laws have been enacted in many of the coastal states, but are most prevalent in California, Florida and Hawaii. Uncertainty as to whether anchoring is an act of navigation, thereby being a constitutional right, has resulted in confusion among boaters, legal authorities and policy makers. In an attempt to clarify the uncertainty surrounding this issue, a lawsuit challenging the constitutionality of anchoring laws within the State of Hawaii …
A Marina Leasing Proposal For The State Of Rhode Island, William A. Archambault
A Marina Leasing Proposal For The State Of Rhode Island, William A. Archambault
Marine Affairs Theses and Major Papers
This thesis examines whether Rhode Island has the authority to lease marinas their submerged lands, and if so, is the fee structure of the CRMC's proposed plan equitable to marinas in the State? The thesis determined that under the powers of the Public Trust Doctrine, Rhode Island has the right to implement a marina leasing program, but implementation of a program may prove to be problematic for the State. The thesis identified that the CRMC's proposed lease rate would be inequitable to marinas in Rhode Island. Marinas subject to the CRMC program would pay the same lease fee per slip, …

The Arctic Environmental Protection Strategy: A Comparison With The Approach Of The Unep Regional Seas Programme, Vinton Valentine
Marine Affairs Theses and Major Papers
In the past two decades, there has been a rise in the number of multilateral regional agreements for marine environmental protection. A large proportion of these regional agreements are the result of the United Nations Environment Programme's (UNEP) Regional Seas Programme. While there are thirteen regional seas under the Programme, the Arctic Ocean is not, and never was, one of them. In describing concerns regarding the Arctic environment and approaches to handle them, a number of commentators have proposed the application of UNEP Regional Seas Programme approach to the Arctic region. However, despite an attempt from the Inuit Circumpolar Conference …

Conservation And Management Of Sri Lanka's Coastal Resources Through The Experience Of Other Countries, K.W.P. Thilakaratna
Marine Affairs Theses and Major Papers
After Sri Lanka's independence in 1948, the economic importance of the coastal areas had intensified due to development of commercial and fishery harbors, transportation, communication, and recreational facilities. Opportunities in the public administration, industry, and education sectors were other main attractions. With the introduction of international tourism in 1970, economic development of coastal areas increased further. In addition to the job opportunities provided by the industrial and commercial sectors, many people were engaged in other activities depending on coastal resources, including fishing and mining activities. Prior to 1978, there was no proper authority or mechanism to address coastal issues. legislation …
Fresh Water To Arabia By Vlcc-Fact Or Folly?, Joseph P. Power
Fresh Water To Arabia By Vlcc-Fact Or Folly?, Joseph P. Power
Marine Affairs Theses and Major Papers
Population growth, industrial development and the esoteric goals of national self-sufficiency in water and food propels the arid nations of Arabia in a voracious scavenge for alternative resources of fresh water as depletion and contamination of the natural aquifers have reached critical proportions. Desalination of sea water is currently the preferred alternative source of fresh water. Recent misgivings concerning the antroprogenic discharge of desalination effluent (i.e. high temperature and high saline water) into the semi-enclosed, epicontinental waters of the Arabian Gulf question the sustainability of this process. Demonstrable deleterious affects of such a process on the marine ecosystem of the …

Publications (WR)
Cover is an important component of aquatic habitat and fisheries management. Fisheries biologists often try to improve habitats through the addition of natural and artificial material to improve cover diversity and complexity. Habitat-improvement programs range from submerging used Christmas trees to more complex programs using sophisticated artificial habitat modules. Used automobile tires have been employed in the large scale construction of reefs and fish attractors in marine environments and to a lesser extent in freshwater and have been recognized as a durable, inexpensive and long-lasting material which benefits fishery communities.
Recent studies by the U.S. Bureau of Reclamation have quantified …

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 …
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 …
Conservation Easements As A Forest Management Strategy, C. Edwin Meadows Jr., Donald J. Mansius
Conservation Easements As A Forest Management Strategy, C. Edwin Meadows Jr., Donald J. Mansius
Maine Policy Review
Conservation easements have become an increasingly popular way of protecting private lands that have public value. Maine, like other northeastern states, has a particular interest in conservation strategies given among other things, its natural resource-dependent economy. C. Edwin Meadows, Commissioner of the Maine Department of Conservation (MDOC), and Donald J. Mansius, the Northern Forest Lands Coordinator for MDOC, address the forest management aspects of conservation easements and provide examples of easement land where forest management is permitted. An accompanying sidebar by Chris Spruce describes a conservation easement that has existed for more than a down years along the Penobscot River …
