Integrated Estuary Governance, Mary Jane Angelo, J.W. Glass May 2021

Integrated Estuary Governance, Mary Jane Angelo, J.W. Glass

William & Mary Environmental Law and Policy Review

Estuaries are complex, dynamic ecosystems that play a critical role in supporting crucial economic industries, such as commercial fishing and tourism, and providing the resources necessary to sustain coastal communities. A range of anthropogenic environmental stressors are threatening the health of estuaries throughout the world. Traditional top-down single resource focused environmental regulatory approaches have proved inadequate to protect and restore estuarine systems. In recent years, scientific and legal academics, as well as policymakers, have called for more holistic participatory approaches to addressing environmental challenges. Drawing on the literature on ecosystem management, integrated water resources management, collaborative governance, and adaptive management, …


Saltbushes For Dryland Salinity Management In Western Australia, Department Of Primary Industries And Regional Development, Western Australia May 2021

Saltbushes For Dryland Salinity Management In Western Australia, Department Of Primary Industries And Regional Development, Western Australia

Natural resources factsheets

Saltland pastures always have a range of plant species, even in dense saltbush plantations. Saltbush will often change the watertable and surface soil characteristics enough for other plants to colonise. The understorey plants are often the most productive component of saltbush pastures.

This page provides information about each of the saltbushes that can be used in these mixed salt-tolerant pastures.

The Department of Primary Industries and Regional Development recommends that saltland management is part of a whole farm – or preferable whole catchment – plan.

Students’ Civic Engagement Self-Efficacy Varies Across Socioscientific Issues Contexts, Jenny Dauer, Amanda E. Sorensen, Jena Wilson May 2021

Students’ Civic Engagement Self-Efficacy Varies Across Socioscientific Issues Contexts, Jenny Dauer, Amanda E. Sorensen, Jena Wilson

School of Natural Resources: Faculty Publications

In STEM learning focused on science literacy, socioscientific issues instruction is often proposed as a way to bolster students’ civic engagement, however few studies in science education have explicitly examined this connection. We define civic engagement as the work of influencing legitimately public matters using means within the existing political structure. In this work we investigate students’ feelings of self-efficacy for this type of civic engagement in the context of four socioscientific issues (prairie dog conservation, food insecurity, biofuels and water conservation). This study was in the context of a large enrollment introductory science college course, where students used a …


International Migration From The Latin American-Caribbean Region: Taking Environmental Indicators Into Consideration, Chelsea Wepy May 2021

International Migration From The Latin American-Caribbean Region: Taking Environmental Indicators Into Consideration, Chelsea Wepy

Student Theses and Dissertations

International migration, the act of leaving one’s country to permanently settle in another country, is driven by many socio economic/political factors, such as lack of economic opportunity, access to education, governmental corruption, and violence. These factors have proven to be the reason that many citizens within the Latin American-Caribbean region either choose or are forced to relocate internationally. While these factors are important to consider independently; these issues are often exacerbated by changes in the natural environment. The objective of my paper is to highlight the importance of considering changes in the natural environment. In doing so, I hope to …

Conceptual Framework Linking Resource Size And Recreational Use, Derek Kane May 2021

Conceptual Framework Linking Resource Size And Recreational Use, Derek Kane

School of Natural Resources: Dissertations, Theses, and Student Research

Participation in recreational activities at natural resource systems is important to many people. However, the use of these resource systems can cause negative social and ecological impacts. To manage the potential negative impacts of resource use, natural resource managers must have the ability to quantify and monitor the amount of use that is occurring. Unfortunately, it is difficult and costly to quantify and monitor resource system use. Natural resource management would benefit from uncovering a simple, easily accessible metric that could predict resource system use. The size of a resource system is related to social and ecological aspects of the …

Evaluating Urban Parks Accessibility And Equity: A Case Study Of Hartford, Ct And New Haven, Ct, Natalie Roach, Mara Tu

Honors Scholar Theses

Public parks provide cities with environmental benefits, positive health effects, recreational opportunities, community building, educational spaces, and public amenities. However, certain populations have been systematically denied their fair share of these benefits because of unjust practices in the creation and maintenance of urban parks. With a lens of environmental justice, the goal of this research was to assess park quality and accessibility of two Connecticut cities, Hartford and New Haven, by gathering publicly available information as well as using GIS tools.

The Trust for Public Land (TPL) has an existing ParkScore rating system that evaluates the quality of a city’s …


A Fusion Of Remotely Sensed Data To Map The Impervious Surfaces Of Growing Cities Of Punjab, Pakistan, Binita Shrestha May 2021

A Fusion Of Remotely Sensed Data To Map The Impervious Surfaces Of Growing Cities Of Punjab, Pakistan, Binita Shrestha

UNLV Theses, Dissertations, Professional Papers, and Capstones

Urban population is expected to exceed 70% of the world’s total by the middle of the 21st century. Thus, growth in number as well as the sizes of the cities are certain in the near future. The urbanization rates will be much higher in the developing countries than the developed. Such phenomena are accompanied by conversion of land cover from its natural use to built up environment to accommodation growing population. Built up surfaces include road networks, buildings, parking lots and pathways. They are permanently impervious and hydrologically active surfaces. Large volume and discharges of runoff characterize impervious surfaces with …

Population Genomics Of Invasive Rodents On Islands: Genetic Consequences Of Colonization And Prospects For Localized Synthetic Gene Drive, Kevin P. Oh, Aaron B. Shiels, Laura Shiels, Dimitri V. Blondel, Karl J. Campbell, J. Royden Saah, Alun L. Lloyd, Paul Q. Thomas, Fred Gould, Zaid Abdo, John R. Godwin, Antoinette J. Piaggio

United States Department of Agriculture Wildlife Services: Staff Publications

Introduced rodent populations pose significant threats worldwide, with particularly severe impacts on islands. Advancements in genome editing have motivated interest in synthetic gene drives that could potentially provide efficient and localized suppression of invasive rodent populations. Application of such technologies will require rigorous population genomic surveys to evaluate population connectivity, taxonomic identification, and to inform design of gene drive localization mechanisms. One proposed approach leverages the predicted shifts in genetic variation that accompany island colonization, wherein founder effects, genetic drift, and island-specific selection are expected to result in locally fixed alleles (LFA) that are variable in neighboring nontarget populations. Engineering …


Nitrogen Supply And Physical Disturbance Shapes Arctic Stream Nitrogen Uptake Through Effects On Metabolic Activity, Maria Myrstener, Steven A. Thomas, Reiner Giesler, Ryan A. Sponseller Apr 2021

Nitrogen Supply And Physical Disturbance Shapes Arctic Stream Nitrogen Uptake Through Effects On Metabolic Activity, Maria Myrstener, Steven A. Thomas, Reiner Giesler, Ryan A. Sponseller

School of Natural Resources: Faculty Publications

1. Climate change in the Arctic is altering the delivery of nutrients from terrestrial to aquatic ecosystems. The impact of these changes on downstream lakes and rivers is influenced by the capacity of small streams to retain such inputs. Given the potential for nutrient limitation in oligotrophic Arctic streams, biotic demand should be high, unless harsh environmental conditions maintain low biomass standing stocks that limit nutrient uptake capacity.

2. We assessed the drivers of nutrient uptake in two contrasting headwater environments in Arctic Sweden: one stream draining upland tundra and the other draining an alluvial valley with birch forest. At …


Consumer Food Waste Behaviors In Relation To Open Date Label Misinterpretation, Daniel Hutchings, Elisabeth Seliga, Anya O'Meara, Anna Blank Apr 2021

Consumer Food Waste Behaviors In Relation To Open Date Label Misinterpretation, Daniel Hutchings, Elisabeth Seliga, Anya O'Meara, Anna Blank

Thinking Matters Student Research Symposium

In the United States, the legal framework for product date labeling is minimal and varies across states. Manufacturers have the discretion to use any date label that they deem appropriate, and this lack of uniformity leaves room for misinterpretation by both retailers and consumers. Previous studies have examined consumer misinterpretation of date labels and how this lack of knowledge correlates to food waste behaviors. This study was aimed at understanding how consumers apply their knowledge about date labels to make decisions about purchasing and discarding food. The research was conducted via an intercept survey outside of a grocery store to …


The Power Of Information: Information, Leak Notices, And Water Conservation In Edina, Mn, Federico Chung Apr 2021

The Power Of Information: Information, Leak Notices, And Water Conservation In Edina, Mn, Federico Chung

Economics Honors Projects

This paper provides evidence on the effects of information provision on households’ water use. I use quarterly household consumption data from a utility in Minnesota to test the effect of a new residential water billing system on households’ water consumption. The updated billing format was possible as the utility transitioned to an automated meter reading (AMR) system. I also study impacts of another source of improved information provision from AMR adoption, faster high-water consumption notices. I find mixed evidence of the impact of personalized information on households’ water use. Households respond to high-consumption notices by significantly reducing consumption, even relative …

Informing Drought Mitigation Policy By Estimating The Value Of Water For Crop Production, Renata Rimsaite, Justin Gibson, Nicholas Brozovic

School of Natural Resources: Faculty Publications

Farmers use irrigation to mitigate drought risk and reduce yield uncertainty. A clear understanding of the monetary value of irrigation water and how it varies across time and space can help to inform farmers and policymakers about the potential impacts of water shortages and reduce uncertainty in decision making. Here, we introduce a framework for understanding the economic value of water used to produce corn in the central High Plains region during the period 2010–2017. Our analysis uses publicly available data for corn price and for irrigated and non-irrigated yields and incorporates irrigation requirement adjustments to account for the hydrologic …

Lewis Honors College Faculty Publications

Surface mining for coal has contributed to widespread deforestation and soil loss in coal mining regions around the world, and particularly in Appalachia, USA. Mined land reforestation is of interest in this and other regions where forests are the dominant pre-mining land use. This study evaluated mine soil development on surface-mined sites reforested according to the Forestry Reclamation Approach, representing a chronosequence of time ranging from 0 to 19 years after reclamation. Soils were sampled in depth increments to 50 cm and analyzed for a suite of soil physical and chemical characteristics. Overall, soil fines (silt + clay) tended to …


Considering The Use Of The Terms Strain And Adaptation In Prion Research, Robert M. Zink Apr 2021

Considering The Use Of The Terms Strain And Adaptation In Prion Research, Robert M. Zink

School of Natural Resources: Faculty Publications

Evolutionary biologists and disease biologists use the terms strain and adaptation in Chronic Wasting Disease (CWD) research in different ways. In evolutionary biology, a strain is a nascent genetic lineage that can be described by a genealogy, and a phylogenetic nomenclature constructed to reflect that genealogy. Prion strains are described as showing distinct host range, clinical presentation, disease progression, and neuropathological and PrP biochemical profiles, and lack information that would permit phylogenetic reconstruction of their history. Prion strains are alternative protein conformations, sometimes derived from the same genotype. I suggest referring to prion strains as ecotypes, because the variant phenotypic …

Recognizing the imperative to evaluate species recovery and conservation impact, in 2012 the International Union for Conservation of Nature (IUCN) called for development of a “Green List of Species” (now the IUCN Green Status of Species). A draft Green Status framework for assessing species’ progress toward recovery, published in 2018, proposed 2 separate but interlinked components: a standardized method (i.e., measurement against benchmarks of species’ viability, functionality, and preimpact distribution) to determine current species recovery status (herein species recovery score) and application of that method to estimate past and potential future impacts of conservation based on 4 metrics (conservation legacy, …

Moderate Grazer Density Stabilizes Forage Availability More Than Patch Burning In Low-Stature Grassland, Edward J. Raynor, Devan Allen Mcgranahan, James R. Miller, Diane M. Debinski, Walter H. Schacht, David M. Engle

School of Natural Resources: Faculty Publications

Spatially patchy fire creates landscape-level diversity that in turn stabilizes several rangeland ecosystem services, including forage production and habitat availability. To enhance biodiversity and livestock production, efforts are underway to restore fire regimes in rangelands throughout the Great Plains. However, invasive species such as tall fescue Schedonorus arundinaceus syn. Festuca arundinacea, initially introduced for forage production, hamper prescribed fire use. Grazer density, or stocking rate, modulates the effect of patchy fire regimes on ecological patterns in invaded, seminatural rangeland pastures. We compare three diversity–stability responses—temporal variability in aboveground plant biomass, portfolio effects among plant functional groups, and beta diversity in …

United States Department of Agriculture Wildlife Services: Staff Publications

Reptiles utilize a variety of environmental cues to inform and drive animal behavior such as chemical scent trails produced by food or conspecifics. Decrypting the scent-trailing behavior of vertebrates, particularly invasive species, enables the discovery of cues that induce exploratory behavior and can aid in the development of valuable basic and applied biological tools. However, pinpointing behaviors dominantly driven by chemical cues versus other competing environmental cues can be challenging. Y-mazes are common tools used in animal behavior research that allow quantification of vertebrate chemosensory behavior across a range of taxa. By reducing external stimuli, Y-mazes remove confounding factors and …

Carbamazepine (CBZ) is the most frequently detected pharmaceutical residues in aquatic environments effluent by wastewater treatment plants. Batch and column experiments were con-ducted to evaluate the removal of CBZ from ultra-pure water and wastewater treatment plant (WWTP) effluent using raw zeolitic tuff (RZT) and surfactant modified zeolite (SMZ). Point zero net charge (pHpzc), X-ray diffraction (XRD), X-ray fluorescence (XRF), and Fourier Transform Infrared (FTIR) were investigated for adsorbents to evaluate the physiochemical changes resulted from the modification process using Hexadecyltrimethylammonium bromide (HDTMA-Br). XRD and FTIR showed that the surfactant modification of RZT has created an amorphous surface with new alkyl …


Reimagining The Duck Stamp, Hunting Licensure And Public Land Preservation, Alec Wayne Boyd-Devine Apr 2021

Reimagining The Duck Stamp, Hunting Licensure And Public Land Preservation, Alec Wayne Boyd-Devine

Masters Theses & Specialist Projects

The American Migratory Bird Hunting and Conservation Stamp, or Duck Stamp, is a form of licensure issued by the Federal Government for waterfowl hunters. Why do physical stamps act as licensure to hunt waterfowl on both public and private land in the United States? How did the stamp become the key that grants access to resources that supposedly should be owned by the public? The duck stamp has been well-documented in conservation communities as a resource which has made significant positive impacts on the environment. The increase of anti-hunting sentiments in our society combined with fewer hunters per capita may …
