Policy On Restocking And Stock Enhancement In Western Australia, Department Of Fisheries Western Australia.
Fisheries Management Papers
The practice of releasing hatchery-reared fish into existing populations to augment fishing (stock enhancement) or restore depleted spawning biomass (restocking) has occurred around the world for decades with varying degrees of success. The underpinning concept is to produce and release fish into wild populations to increase their abundance, catch rates and/or fishery yields
If restocking and stock enhancement activities are to be successful, they should have clear objectives and be well planned and targeted at situations where there is a reasonable expectation of having a beneficial effect.

Using Economic Instruments To Develop Effective Management Of Invasive Species: Insights From A Bioeconomic Model, Shana M. Mcdermott, Rebecca E. Irwin, Brad W. Taylor
Using Economic Instruments To Develop Effective Management Of Invasive Species: Insights From A Bioeconomic Model, Shana M. Mcdermott, Rebecca E. Irwin, Brad W. Taylor
Dartmouth Scholarship
Economic growth is recognized as an important factor associated with species invasions. Consequently, there is increasing need to develop solutions that combine economics and ecology to inform invasive species management. We developed a model combining economic, ecological, and sociological factors to assess the degree to which economic policies can be used to control invasive plants. Because invasive plants often spread across numerous properties, we explored whether property owners should manage invaders cooperatively as a group by incorporating the negative effects of invader spread in management decisions (collective management) or independently, whereby the negative effects of invasive plant spread are ignored …
Optimal Placement Of Off-Stream Water Sources For Ephemeral Stream Recovery, Matthew Rigge, Alexander Smart, Bruce Wylie
Optimal Placement Of Off-Stream Water Sources For Ephemeral Stream Recovery, Matthew Rigge, Alexander Smart, Bruce Wylie
Natural Resource Management Faculty Publications
Uneven and/or inefficient livestock distribution is often a product of an inadequate number and distribution of watering points.Placement of off-stream water practices (OSWP) in pastures is a key consideration in rangeland management plans and is criticalto achieving riparian recovery by improving grazing evenness, while improving livestock performance. Effective OSWPplacement also minimizes the impacts of livestock use radiating from OSWP, known as the ‘‘piosphere.’’ The objective of thisstudy was to provide land managers with recommendations for the optimum placement of OSWP. Specifically, we aimed toprovide minimum offset distances of OSWP to streams and assess the effective range of OSWP using Normalized …

Agriculture In A Water Scarce World, Allison Roberts, Amjad Assi, Bassel Daher, Men Li
Agriculture In A Water Scarce World, Allison Roberts, Amjad Assi, Bassel Daher, Men Li
Student Papers in Public Policy
According to the McKinsey report (2009), the world is facing a water scarcity challenge where agriculture is its predominant consumer. It accounts for approximately 3100 billion m3, or 71 percent of global water withdrawals today, and is expected to increase to 4500 billion m3 by 2030. This increase is due to a number of factors: growing population and the ever growing necessity to cater for its food needs, economic growth, the variability of precipitation trends and increase in global temperatures. In addition to the increase in water scarcity, the agricultural sector faces an enormous challenge of producing …

Ocean Sustainability, Logan Levan, Joshua Millea, Woo Choi, Mark Powell, David Flint
Student Papers in Public Policy
Oceans cover over 70% of the Earth’s surface area. They provide more than 90% of the world’s oxygen production, account for 200 billion pounds of food each year, regulate the global climate, and are the primary mode of global shipping traffic (“www.marinebio.org”). With such social, economic, and environmental value, there is a clear need to enact sustainable policies and practices concerning marine zones.

Urban Agriculture Stormwater Management In California Cities, Rachel L. Cohen
Urban Agriculture Stormwater Management In California Cities, Rachel L. Cohen
Master's Theses
Cities within California are beginning to incorporate urban agriculture into their land use designations. Prompted by residents and local organizations, cities are hoping to capture the benefits that urban agriculture provides. Research has shown that urban agriculture renews and beautifies neighborhoods, provides healthy food choices, increases public health, has the potential to help with stormwater runoff, creates jobs, and fosters community. In the last few years, several California cities have made headlines as they have adopted new zoning codes that include urban agriculture.
In reviewing these new zoning codes and exploring the topic of urban agriculture, it became evident that …
A Natural Resource Condition Assessment For Sequoia And Kings Canyon National Parks, Appendix 16 - Bats, Alice Chung-Maccoubrey
A Natural Resource Condition Assessment For Sequoia And Kings Canyon National Parks, Appendix 16 - Bats, Alice Chung-Maccoubrey
United States National Park Service: Publications
Scope of Analysis
North American bats are highly unique animals that have historically been overlooked by land managers and misunderstood by the public. Bats are unique as the only true flying mammals and due to their exceptionally long lives (5-15 years) and unusually low reproductive rates (typically one young per year) for their small size. Most North American bat species are insectivorous, serve as the primary predators of nocturnal insects, and can consume up to one-third of their weight in insects per night. Thus, bats play a role in regulating insect populations, insect-related ecological processes, and nutrient redistribution and cycling …
Source And Magnitude Of Error In An Inexpensive Image-Based Water Level Measurement System, Troy E. Gilmore, François Birgand, Kenneth W. Chapman
Source And Magnitude Of Error In An Inexpensive Image-Based Water Level Measurement System, Troy E. Gilmore, François Birgand, Kenneth W. Chapman
School of Natural Resources: Faculty Publications
Recent technological advances have opened the possibility to use webcams and images as part of the environmental monitoring arsenal. The potential sources and magnitude of uncertainties inherent to an image-based water level measurement system are evaluated in an experimental design in the laboratory. Sources of error investigated include image resolution, lighting effects, perspective, lens distortion and water meniscus. Image resolution and meniscus were found to weigh the most in the overall uncertainty of this system. Image distortion, although largely taken into account by the software developed, may also significantly add to uncertainty. Results suggest that ‘‘flat’’ images with little distortion …

The Role Of The Ocean Industry In The Chinese National Economy: An Input-Output Analysis, Rui Zhao
The Role Of The Ocean Industry In The Chinese National Economy: An Input-Output Analysis, Rui Zhao
Working Papers
The OEAS (Ocean Economy Accounting System) has been established in China for 6 years. However, the economic impact of the ocean economy in China’s national economy has not yet been understood clearly at the national or regional levels. The direct impact of ocean industries in China at national and regional levels has been compiled for the period of 2001-2011, but it is still unclear what the overall economic impacts of ocean industries are in the national economy, and how the ocean industries interact with other industries in the national economy. China is similar to other ocean countries in that, - …

Eaton, Matthew H. Langholtz, Philip Morefield, Caroline E. Ridley, Laura Vimmerstedt, Steve Peterson, Brian W. Bush
Dartmouth Scholarship
Biofuels are expected to be a major contributor to renewable energy in the coming decades under the Renewable Fuel Standard (RFS). These fuels have many attractive properties including the promotion of energy independence, rural development, and the reduction of national carbon emissions. However, several unresolved environmental and economic concerns remain. Environmentally, much of the biomass is expected to come from agricultural expansion and/or intensification, which may greatly affect the net environmental impact, and economically, the lack of a developed infrastructure and bottlenecks along the supply chain may affect the industry's economic vitality. The approximately 30 million acres (12 million hectares) …
Fluctuating Viability Selection On Morphology Of Cliff Swallows Is Driven By Climate, Charles R. Brown, Mary Bomberger Brown, Erin A. Roche
Fluctuating Viability Selection On Morphology Of Cliff Swallows Is Driven By Climate, Charles R. Brown, Mary Bomberger Brown, Erin A. Roche
School of Natural Resources: Faculty Publications
The extent to which fluctuating selection can maintain evolutionary stasis in most populations remains an unresolved question in evolutionary biology. Climate has been hypothesized to drive reversals in the direction of selection among different time periods and may also be responsible for intense episodic selection caused by rare weather events. We measured viability selection associated with morphological traits in cliff swallows (Petrochelidon pyrrhonota) in western Nebraska, USA, over a 14-year period following a rare climatic event. We used mark-recapture to estimate the annual apparent survival of over 26 000 individuals whose wing, tail, tarsus, and bill had been …
Cost-Benefit Analysis Of Farmer Training In Ghanaian Cocoa Farming, Michael Norton
Cost-Benefit Analysis Of Farmer Training In Ghanaian Cocoa Farming, Michael Norton
Agricultural Economics and Agribusiness Undergraduate Honors Theses
While billions of dollars flow into low-income countries each year to help alleviate poverty, assessing the effectiveness of these dollars is a challenging task. The literature is rich in studies that measure the benefits of rural development programs. However, many of these studies lack a temporal dimension because they measure cost and benefits for only capital investments and for only a single, static year, while not accounting for skill enhancement. By only measuring net producer benefits during the life of the development program, the cost-benefit analyses (CBA) may not truly capture the full net benefits of a given program. In …
Evaluation Of Dormant-Season Herbicide Treatment Methods For Chinese Privet At Congaree National Park, Karen Vaughn
Evaluation Of Dormant-Season Herbicide Treatment Methods For Chinese Privet At Congaree National Park, Karen Vaughn
All Theses
Chinese privet (Ligustrum sinense Lour.) is a non-native invasive shrub that has become ubiquitous throughout the southeastern United States. There is a large infestation of privet at Congaree National Park in South Carolina, and the National Park Service is interested in controlling it with dormant-season foliar herbicide treatments. The primary objective of this study was to determine which combination of herbicide and applicator provides the most effective control of privet, while minimizing damage to non-target plants. Another objective was to document impacts of privet invasion on Congaree's plant communities.
Seven vegetation plots were installed in each of five large privet …

Geotechnics And Regionalism: The Lineage Of Thought From John Wesley Powell To Benton Mackaye, Nikkilee Cataldo
Geotechnics And Regionalism: The Lineage Of Thought From John Wesley Powell To Benton Mackaye, Nikkilee Cataldo
Muskie School Capstones and Dissertations
John Wesley Powell and Benton MacKaye, each developed exceptionally comprehensive and innovative regional planning visions that had a great deal in common. They both were Jeffersonian idealists, who considered those who tilled the soil and worked the land for primary production a class of men above all the rest.
This paper will explore some of the fundamental theory behind the work of both Powell and MacKaye, as well as examples of the plans that they developed. It will become clear that the two men were working from very similar theoretical vantage points, though in relatively different socio-political eras. It will …
A Policymaker's Guide To Feed-In Tariffs: Encouraging A Responsible Transition To Renewable Electricity In California, Roland P. Thayer
A Policymaker's Guide To Feed-In Tariffs: Encouraging A Responsible Transition To Renewable Electricity In California, Roland P. Thayer
Pomona Senior Theses
The feed-in tariff is a flexible, yet effective mechanism in promoting the proliferation of renewable electricity in California. The tariff creates a stable investment environment that protects both the utilities and the renewable electricity generators. Not only does the system foster capacity growth, but also technological advancement to the point where renewable electricity can compete in the market without assistance. From an environmental standpoint, the feed-in tariff contributes significantly towards achieving the emissions reduction goals set forth by AB32 without causing harmful increases to electricity prices.
The feed-in tariff model has been used in countries all over the world and …
Predicting Groundwater Trading Participation In The Upper Republican River Natural Resource District, Elizabeth M. Juchems
Predicting Groundwater Trading Participation In The Upper Republican River Natural Resource District, Elizabeth M. Juchems
Department of Agricultural Economics: Dissertations, Theses, and Student Research
The goal of this thesis is to predict participation in groundwater trading and the directions of trades among participants. Specifically, the paper considers both formal and informal trading of groundwater used for crop irrigation purposes and attempts to identify those characteristics that predict the probability of trade participation and whether an individual is a buyer or seller of groundwater rights. While the public benefits from efficient use of groundwater include adequate stream flow in hydrologically connected areas and future use of groundwater supplies, there are significant private benefits to landowners especially in water-short areas. Groundwater trading can help move water …
Advocacy For Marine Management: Contributions To A Policy Advocacy Initiative In The Maldives, Neal Collins
Advocacy For Marine Management: Contributions To A Policy Advocacy Initiative In The Maldives, Neal Collins
Capstone Collection
On June 5, 2009 a 42-‐km2 area of coral reef situated in the Alif Dhaalu (South Ari) atoll of the Republic of Maldives was designated the South Ari Atoll Marine Protected Area (S.A. MPA) due to a globally significant whale shark aggregation site. The whale shark is notorious for its gargantuan size and docile nature, which has led to a burgeoning tourist industry that gives people the opportunity to swim with the gentle giants in tropical sites such as the Maldives. The S.A. MPA receives tens of thousands of visitors a year that engage in whale shark excursions, however, there …
Cougar Predation Behavior In North-Central Utah, Dustin L. Mitchell
Cougar Predation Behavior In North-Central Utah, Dustin L. Mitchell
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Today’s ability to apply global positioning systems (GPS) collars to wild animals and track their movements, without inadvertently disrupting their daily routine, is a major benefit to wildlife research. Cougars are carnivorous predators that have been identified as being one of several possible causes for recent mule deer population declines throughout the Western United States. Past cougar predation studies have relied on snow tracking, radio-collar tracking, and modeling techniques to estimate cougar prey use and predation rates. These methods rely heavily on weather conditions, logistical availabilities, and broad assumptions, which have led to a wide range of predation rate estimates. …

Enhancing Coastal Resilience: Perspectives On Valuing Ri Coastal Lands, Kyle Nyskohus
Honors Projects in Science and Technology
This paper discusses coastal resilience as an organizing framework for future policymaking, coastal planning, and insurance decisions, and explores the different perspectives of the value of ecosystems held by various stakeholders in Rhode Island’s coastal communities. A grounded theory approach was used in an effort to abstract general insights from the substantive but isolated areas of coastal management and economics. Special attention is given to the perspectives of municipal decision makers, the National Flood Insurance Program, natural economists, and real estate developers. We have (1) conducted a statistical analysis of environmental spending of RI towns, (2) identified key models for …

Phylogeography Of The California Gnatcatcher (Polioptila Californica) Using Multilocus Dna Sequences And Ecological Niche Modeling: Implications For Conservation, Robert M. Zink, Jeffrey G. Groth, Hernan Vázquez-Miranda
School of Natural Resources: Faculty Publications
An important step in conservation is to identify whether threatened populations are evolutionarily discrete and significant to the species. A prior mitochondrial DNA (mtDNA) phylogeographic study of the California Gnatcatcher (Polioptila californica) revealed no geographic structure and, thus, did not support the subspecies validity of the threatened coastal California Gnatcatcher (P. c. californica). The U.S. Fish and Wildlife Service concluded that mtDNA data alone were insufficient to test subspecies taxonomy. We sequenced eight nuclear loci to search for historically discrete groupings that might have been missed by the mtDNA study (which we confirmed with new ND2 …
