A Resilience Assessment Of The Ramla Valley System, Gozo, Mykel Fenech
A Resilience Assessment Of The Ramla Valley System, Gozo, Mykel Fenech
Masters Theses, 2010-2019
The investigation delves into the application of the resilience concept to the ecological and anthropogenic systems of Ramla Valley, Gozo. The Resilience Assessment, the first of its kind attempted in the Islands, takes a holistic approach to study a system by considering the various system components and related pressures. Components considered include agricultural, ecological, sediment (beaches and dunes) and landscape. Current governance impacting the system was also considered. Methods used in this study were based on guidelines provided by the Resilience Alliance and supported by data derived from previous studies, interviews with interested parties, on-site observations, and comparative studies of …
Spatial And Temporal Participation In Recreational Fishing, Dustin R. Martin
Spatial And Temporal Participation In Recreational Fishing, Dustin R. Martin
School of Natural Resources: Dissertations, Theses, and Student Research
Buffering inland fisheries against large-scale changes in ecosystem function, climate regimes, and societal valuations of natural resources requires progressive management approaches that incorporate fish and angler dynamics at large spatial and temporal scales. Current paradigms of inland fishery management generally utilize waterbody-specific, fish-centric frameworks designed to regulate fish populations directly, and anglers indirectly, through fish stock enhancement and harvest regulation. In reality, anglers are the most manageable component of a fishery but management of anglers requires explicit consideration of their behavior (e.g., spatial and temporal patterns of participant use), which, unlike fish populations, operates at a scale larger than a …

York County, Virginia Shoreline Inventory Report Methods And Guidelines, Marcia Berman, Karinna Nunez, Sharon Killeen, Tamia Rudnicky, Carl Hershner, Kory Angstadt, David Stanhope, David Weiss, Karen Duhring, Christine Tombleson
Reports
The data inventory developed for the Shoreline Inventory is based on a three tiered shoreline assessment approach. In most cases this assessment characterizes conditions that can be observed from a small boat navigating along the shoreline. The three tiered shoreline assessment approach divides the shorezone into three regions: 1) the immediate riparian zone, evaluated for land use; 2) the bank, evaluated for height, stability, cover and natural protection; and 3) the shoreline, describing the presence of shoreline structures for shore protection and recreational purposes.
The 2009 Inventory for York County was updated using on-screen, digitizing techniques in ArcMap v10.0 while …

The Effect Of Consumerism And Regulation On Household Solid Waste Management In The United States And Germany: A Comparative Study, Amir Vafa
Amir Vafa
Private household recycling is a significant aspect of consumerism in economically developed countries and the inevitable question of household waste management has gained more importance among municipalities in recent years. The present study examined the effect of regulation on household solid waste management. Within a comparative, qualitative framework, the study explored and evaluated the pro-regulatory effects in Germany and the anti-regulatory policies in the United States by means of comparing two similar communities, Lincoln, Nebraska and Augsburg, Germany. By examining the present legislations, official documents, legal and operational procedures, and other relevant artifacts, laws, regulations and the degree of their …
Factors Influencing Nest Site Selection By Wood Turtles (Glyptemys Insculpta) In An Altered Forest Landscape, Ellery Ruther
Factors Influencing Nest Site Selection By Wood Turtles (Glyptemys Insculpta) In An Altered Forest Landscape, Ellery Ruther
Theses & Honors Papers
There have been many studies concerning wood turtle (Glyptemys insculpta) nest site selection, including studies that evaluate nest site conditions when stream sand banks are not available. However, because of the unique landscape at our study site (high gradient, first order streams) and rapidly diminishing wood turtle populations in Virginia, I am evaluating wood turtle nest site selection. Nine physiographic and vegetative characteristics from nest, positive, negative-one and negative-two control locations were evaluated using binomial generalized linear models and then best fit models were chosen using Akaike's Information Criterion (AIC). It was found that in lieu of typical stream …
Virtual Interactions With Real-Agents For Sustainable Natural Resource Management, Tyler Pierce
Virtual Interactions With Real-Agents For Sustainable Natural Resource Management, Tyler Pierce
Electronic Theses and Dissertations
Common pool resource management systems are complex to manage due to the absence of a clear understanding of the effects of users’ behavioral characteristics. Non-cooperative decision making based on individual rationality (as opposed to group rationality) and a tendency to free ride due to lack of trust and information about other users’ behavior creates externalities and can lead to tragedy of the commons without intervention by a regulator. Nevertheless, even regulatory institutions often fail to sustain natural common pool resources in the absence of clear understanding of the responses of multiple heterogeneous decision makers to different regulation schemes. While modeling …

The Shoreline Inventory Summary Tables quantify observed conditions based on river systems, such as the combined length of linear features (e.g. shoreline miles surveyed, miles of bulkhead and revetment), the total number of point features (e.g. docks, boathouses, boat ramps) & total acres of polygon features (tidal marshes).
