Use Of High Pressure Liquid Chromatography To Detect And Quantify Oxytetracycline Marks In Walleye Otoliths And Dorsal Spines, Michael J. Hawkins Jan 2002

Use Of High Pressure Liquid Chromatography To Detect And Quantify Oxytetracycline Marks In Walleye Otoliths And Dorsal Spines, Michael J. Hawkins

Electronic Theses and Dissertations

Oxytetracycline (OTC) is used to chemically mark calcified structures in walleye Stizostedion vitreum fry and fingerlings. Current visual methods for detection of these marks are subjective, and biologists are unable to quantify the amount of OTC in a sample. The goal of this study was to determine if high pressure liquid chromatography (HPLC) is a feasible and superior alternative for detecting and quantifying OTC in otoliths of fry-marked and spines of fingerlingmarked walleyes. Study objectives were to validate methodology of extraction of OTC from calcified tissue, detect and quantify extracted OTC using HPLC, and determine a cost comparison of current …

Call Parameters And Facial Features In Bats: A Surprising Failure Of Form Following Function, Amanda Goudy-Trainor, Patricia W. Freeman Jan 2002

Call Parameters And Facial Features In Bats: A Surprising Failure Of Form Following Function, Amanda Goudy-Trainor, Patricia W. Freeman

School of Natural Resources: Faculty Publications

We attempted to correlate echolocation call parameters to a comprehensive array of ear and nose measurements from 12 families of bats. Surprisingly, we failed to find any significant relationships. We did find consistent differences between nasal and oral emitters such as: (a) nasal emitters have higher frequencies with maximum energy for their size than oral emitters, (b) nasal emitting bats tend to have longer, narrower skulls, and (c) nasal emitters have a shorter distance from the nostril to the eye (muzzle length).

Coastal Training Market Analysis: Final Report, Kevin O'Brien, Claudette Robey, Daniel Barasckay, Wendy A. Kellogg, Michael J. Tevesz Jan 2002

Coastal Training Market Analysis: Final Report, Kevin O'Brien, Claudette Robey, Daniel Barasckay, Wendy A. Kellogg, Michael J. Tevesz

All Maxine Goodman Levin School of Urban Affairs Publications

A market is emerging for policy makers in the area of coastal resources management. Individuals, as professionals or private citizens, are frequently called upon to make decisions regarding coastal environmental issues. The context in which they do so varies considerably; thus education and training in this topic area serves to heighten and expand the knowledge base of the coastal decision-maker.

Brownfields One-Stop Shop Forum: A Test Strategy For Inter-Agency Cooperation In Northeast Ohio, Kevin O'Brien, Kirstin S. Toth Jan 2002

Brownfields One-Stop Shop Forum: A Test Strategy For Inter-Agency Cooperation In Northeast Ohio, Kevin O'Brien, Kirstin S. Toth

All Maxine Goodman Levin School of Urban Affairs Publications

The Brownfields One Stop Shop (BOSS) is the culmination of a process created over a year ago that brought together several federal and local public agencies to address the complexities of applying resources to support brownfields redevelopment. The idea was originally developed by the United States Environmental Protection Agency’s Region 5 brownfields Project Manager, Edwin Smith, and by the United States Department of Housing and Urban Development’s Cleveland Office Community Builder, Paul Diegelman. Together, they developed an initial concept for a collaborative introductory meeting, and presented the idea to the Cleveland Federal Executive Board members. The project was accepted as …

River Basin Ecosystem Restoration: A Comparison Of Conservation Authority Efforts (Ontario), Wilfred Gregory Tschirhart Jan 2002

River Basin Ecosystem Restoration: A Comparison Of Conservation Authority Efforts (Ontario), Wilfred Gregory Tschirhart

Theses and Dissertations (Comprehensive)

This thesis reviews a series of river basin ecosystem restoration/enhancement projects carried out under the direction of three individual southern Ontario conservation authorities in their respective river basins. The three authorities are the Grand River Conservation Authority, the Maitland Valley Conservation Authority, and the Upper Thames River Conservation Authority. A review from the published literature dealing with river basins, ecosystems, and environmental management supports the analysis of restoration projects. The criterion by which the literature articles were selected was that they have relevance to the type of environmental issues that are common to the river basins in the study areas. …

Ecosystem Health And Sustainable Livelihoods: Exploring The Prospects In Community-Based Resource Management In The East Mamprusi District, Ghana, Wuni P. Dasori Jan 2002

Ecosystem Health And Sustainable Livelihoods: Exploring The Prospects In Community-Based Resource Management In The East Mamprusi District, Ghana, Wuni P. Dasori

Theses and Dissertations (Comprehensive)

Institutional processes, social and economic trends play a role in defining the outcomes of people’s interaction with and use of their ecosystems. The resource use decisions of households influence the livelihood and health dimensions of ecological change. This thesis identifies community assets and activities, and examines how they both affect human and ecological health, productivity and community sustainability. It studies the relationship between changing biophysical conditions and community well-being in terms of health and livelihood by examining how agro-ecosystem based resource use systems influence community environmental change and vulnerability to health and livelihood problems inherent in their ecosystem. Three communities …

A Dynamic Simulation Model Of Beach Sand Replenishment: A Case Study Of Santa Barbara, California, David Turbow, Steve Norwick, Sajjad Ahmad Jan 2002

A Dynamic Simulation Model Of Beach Sand Replenishment: A Case Study Of Santa Barbara, California, David Turbow, Steve Norwick, Sajjad Ahmad

Civil and Environmental Engineering and Construction Faculty Research

Sediment deprivation from dam installments contributes to beach erosion yet the underlying physical and economic factors linking them together have traditionally been isolated during regional planning. In order to gain a better understanding of the behavior of a managed beach system, a dynamic simulation model was developed incorporating physical and monetary factors influencing the amount of available beach sand. The Santa Barbara littoral cell was chosen as a case study to evaluate the feasibility of beach preservation goals under scenarios in which annual sand replenishment funding, sand prices, or sediment recovery from behind dams were limiting factors to available beach …
