Seasonal Variation And Tracking Of Climate Niche Of A Migratory Bird, Javier Gutiérrez Illán, Guiming Wang, D. Tommy King, Fred L. Cunningham

United States Department of Agriculture Wildlife Services: Staff Publications

Migratory birds inhabit different areas during breeding and non-breeding seasons. Depending on the time of the year, they may utilize different resources available in seasonal habitats, but also are subjected to changing climate regimes during their annual life cycle. Migratory birds may adopt ecological niche tracking to cope with different environmental conditions between breeding and non-breeding grounds. The American White Pelican (Pelecanus erythrorhynchos, hereafter ‘AWPE’) is a short-distance migrant between the Gulf of Mexico coastal regions (nonbreeding grounds) and the Northern Great Plains (breeding grounds) of Canada and the US. The American White Pelican is a piscivore, feeding …

Advanced Science Research Center

As rates of urbanization and climatic change soar, decision-makers are increasingly challenged to provide innovative solutions that simultaneously address climate change impacts and risks and inclusively ensure quality of life for urban residents. Cities have turned to nature-based solutions to help address these challenges. Nature-based solutions, through the provision of ecosystem services, can yield numerous benefits for people and address multiple challenges simultaneously. Yet, efforts to mainstream nature-based solutions are impaired by the complexity of the interacting social, ecological, and technological dimensions of urban systems. This complexity must be understood and managed to ensure ecosystem-service provisioning is effective, equitable, and …

A Comprehensive Bison Management And Research Plan For The Crane Trust, Joshua D. Wiese

Other Publications in Wildlife Management

The Great Plains were once a vast grassland ecosystem, but, due to agricultural and human development, are one of the most endangered ecosystems in North America. What remains is generally fragmented, threatened by invasive species, and lacks the natural ecosystem processes that shaped these grasslands such as periodic wildfire and bison grazing. Since 1978, the Platte River Whooping Crane Maintenance Trust, Inc. (dba “Crane Trust”) has worked to maintain the function of grassland and riparian habitats to benefit endangered Whooping Cranes, Sandhill Cranes, and other migratory bird species. They protect ~8,100 acres, including the largest contiguous portion of lowland tallgrass …

The Demotechnic Index Of Nations, 1980-2018, Camden Rainwater

Geosciences Undergraduate Honors Theses

The Demotechnic Index (DI) is a non-dimensional metric that is the scalar multiple of energy consumption over and above that required for mere subsistence of a national population. Thus, the DI is a measure of energy efficiency that scales a country’s industrial energy consumption (called the total technological energy) and the energy required to meet the metabolic demand of the population (called the total metabolic energy). The DI was created by scientist John Vallentyne in 1982, refined in 1994, but never gained popularity or wide use as a sustainability metric. The objective of this thesis was to re-evaluate the DI …

Temporal Changes In Surface Water Availability: Patterns Of Seasonal Shift On Water Stress In The Conterminous Us Under A Changing Climate, Quinn Montana

Graduate Theses and Dissertations

The argument could be made that there is nothing more valuable on the planet than water. Our lives depend upon it. Climate change is already having an impact on the United States (US) and water stress will be one of the problems we increasingly face in coming decades. Regional research has shown that one or another part of the conterminous US (CONUS) is expected to experience an annual deficit or a surplus in runoff. Further studies have looked at changing patterns over the CONUS as a whole. Other research has focused on a particular season. This work addresses a gap …

Resource management technical reports

This report documents the procedures used to identify suitable locations for irrigation development in the Pilbara region. It is the first study to investigate the potential for irrigated agriculture across the Pilbara. We used a desktop analysis to ascertain water availability and spatial data modelling to determine the potential of the land and soil resource to support irrigated agriculture. This study was part of the Pilbara Hinterland Agricultural Development Initiative (PHADI).

We used existing rangeland land inventory information augmented with digital spatial environmental data, in a process known as map disaggregation, to create soil and landform maps that had a …

Effects Of Forest Management On Early-Successional Avian Species In The Southern Blue Ridge Ecoregion, Michael J. Adams

All Theses

Early-successional habitats are a critical habitat type for Ruffed Grouse (Bonasa umbellus) and Golden-winged Warblers (Vermivora chrysoptera). In the Southern Blue Ridge Ecoregion, early-successional habitats have declined over the last 70 years, and the extent of which Ruffed Grouse and Golden-winged Warblers occupy these habitats at the edge of their ranges is unknown. Understanding the factors that drive the presence or absence of these species in this region is critical to inform quality management of early-successional forests. Additionally, increased knowledge of these species will likely benefit other species of conservation concern that rely on early-successional forests, …

Pasture Biomass Estimation Using Crop Surface Modeling And Vegetation Indices, Brendan Macinnis

All Theses

Biomass estimations are a critical function of any grazing or haylage system. Determination of ideal harvesting or grazing times help optimize the quality and quantity of above-ground biomass (AGB). The objective of this study was to evaluate the use of unmanned aerial vehicles (UAVs) for Alfalfa and Tall Fescue biomass estimations. Using a DJI Mavic Pro, RGB and NDVI images were taken and used to create orthomosaic images. Structure-from-motion (SfM) techniques were used to developed digital elevation models to evaluate the change in canopy height (∆H) between pre- and post-harvests. Change in canopy height (∆H) was shown to provide the …

Vermont Global Warming Solutions Act: The Costs Of Inaction From Land Conversions, Grayson L. Younts

All Theses

The Vermont (VT) Global Warming Solutions Act (GWSA, 2020) sets greenhouse gas (GHG) emissions reduction targets as 26% below 2005 by 2025, 40% below 1990 by 2030 and 80% below 1990 by 2050 for energy-related emissions only. Vermont’s omission of GHG emissions from land conversions can result in significant costs of inaction (COI), which can hinder state’s mitigation and adaptation plans and result in a climate crisis-related risks (e.g., credit downgrade). Science-based spatio-temporal data of GHG emissions from soils as a result of land conversions can be integrated into the conceptual framework of “action” versus “inaction” to prevent GHG emissions. …

Climate-Driven Stock Shifts And Expansions In The U.S. Northeast Shelf: Identifying Challenges, Opportunities, And Barriers Through Fishermen And Manager Perspectives, Sophie A. Swetz

All Theses And Dissertations

Climate-driven warming in the U.S. Northeast Shelf (NES) has led to changes in the spatial distributions of many marine resources. Shifts and expansions of commercially important fish stocks pose major challenges to fishermen and fisheries managers in this region. American lobster (Homarus americanus) in the Gulf of Maine (GOM) is one of these impacted stocks and is projected to continue its shift towards more northern and offshore areas. Continued ocean warming could potentially reduce the GOM lobster stock by up to 60% over the next several decades. Given Maine’s reliance on its lobster fishery—which contributes over 80% of …

The Impact Of Water Infrastructure Inequality On Marginalized Communities, Indra Khalsa

Honors Theses

America’s current system of water infrastructure poses a threat not only to the environment but also to public health. The water crisis reveals the stark inequalities that exist from both an environmental justice and a social justice perspective. There is a growing concern that without adequate investment from federal resources, the problems related to this issue will only worsen the longer they are neglected. There is little information about how specific environmental and social factors combine with water infrastructure to create long-term infrastructure inequalities. However, this thesis explores the disparities in water infrastructure affordability, vulnerability patterns, and environmental hazards. It …

An Investigation Of The Attitudes And Behavioral Outcomes Of Nebraskan Hunters Toward Tick-Borne Disease, Dominic J. Cristiano

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

As changes in climate, land-use, and vegetation alter the landscape of the Great Plains, new threats to public health are emerging. Incidences of tick-borne disease in Nebraska have increased nearly 250% over the past two decades – newly established species like Ixodes scapularis may introduce challenges for health practitioners, including more cases of Lyme disease. Strategies for tick-borne disease prevention must incorporate effective health messaging. Audience segmentation may be a useful technique to provide health communication, as it allows for targeted messaging that speaks to specific attitudes and beliefs of a given population. One tool for usefully segmenting populations is …

Exploring Social Dimensions Of Ecological Restoration In The Removal Of Two Dams On The Elwha River, Joseph Hinnant

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

The United States is approaching a critical juncture regarding aging dam infrastructure. One increasingly common decision has been to remove dams, recreating a free-flowing river. The attention of the literature on ecological restoration is shifting from an ecological focus towards the importance of participation and the social dimensions of restorations. Social situations surrounding a dam removal can lead to expedited success, delays, or abandoned efforts. This study seeks to connect selected social dimensions of dam removals with the broader literature of ecological restoration by exploring social dimensions expressed in public participation in a dam removal process.

Multi-Criteria Evaluation Model For Classifying Marginal Cropland In Nebraska Using Historical Crop Yield And Biophysical Characteristics, Andrew Laws

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

Marginal cropland is suboptimal due to historically low and variable productivity and limiting biophysical characteristics. To support future agricultural management and policy decisions in Nebraska, U.S.A, it is important to understand where cropland is marginal for its two most economically important crops: corn (Zea mays) and soybean (Glycine max). As corn and soybean are frequently planted in a crop rotation, it is important to consider if there is a relationship with cropland marginality. Based on the current literature, there exists a need for a flexible yet robust methodology for identifying marginal land at different scales, which …

Contribution Of A Higher Educational Institution Towards Advancing Sustainability In The West Texas Paso Del Norte Region, Anand Raj

Open Access Theses & Dissertations

Sustainability comprises primarily three elements; environmental, social, and economic, which can be considered the keys to humanityâ??s survival and wellbeing. The pillars can alternately be given informal names: planet, people, and profit. Sustainability is achieved by effectively utilizing available resources through different sustainable development efforts. Generally, groups or entities come together to create sustainable impact in the three primary elements discussed here. City councils, businesses, and higher education institutions are just a few of the entities that engage in sustainability efforts. It is valuable to appraise the role played by a higher education institution in advancing sustainability in the context …

Relative Palatability And Efficacy Of Brodifacoum-25d Conservation Rodenticide Pellets For Mouse Eradication On Midway Atoll, Peter J. Kappes, Shane R. Siers, Israel L. Leinbach, Robert T. Sugihara, Wesley J. Jolley, Jonathan H. Plissner, Elizabeth N. Flint, Kelly L. Goodale, Gregg R. Howald

United States Department of Agriculture Wildlife Services: Staff Publications

Invasive mice (Mus spp.) can negatively impact island species and ecosystems. Because fewer island rodent eradications have been attempted for mice compared to rats (Rattus spp.), less is known about efficacy and palatability of rodenticide baits for mouse eradications. We performed a series of bait acceptance and efficacy cage trials using a standard formulation of brodifacoum-based rodenticide on wild-caught mice from Sand Island, Midway Atoll, to help inform a proposed eradication there. Mice were offered ad libitum brodifacoum pellets along with various alternative food sources, and a “no choice” treatment group received only bait pellets. Mortality in the no choice …

Point Of Use Technologies To Increase Access To Clean Water In Rural Communities, Elena Arroway

Undergraduate Theses, Capstones, and Recitals

Access to clean water is an issue that many communities around the world struggle with. While large-scale efforts such as piping infrastructure have been successful, these are less effective at reaching small, rural communities. To supplement these efforts, point of use (POU) methods for water treatment can be implemented. These include boiling, chemical treatment, filters, and several additional technologies. These have all shown effectiveness in a lab setting, but their implementation in the real world, specifically in rural communities, has not been nearly as effective. In this paper, several different POU methods are evaluated for their effectiveness on a small-scale, …

Using A Geospatial Analysis Tool To Visualize Water Impairments And Engage Stakeholders In The San Bernardino National Forest, Jovany Estrada

Electronic Theses, Projects, and Dissertations

High quality water is an important resource that is integral to supporting environmental and human health. It is essential for economic, social and environmental purposes. Impairments to water resources can be attributed to anthropogenic sources that are associated with terrestrial activities including urban development and agricultural activities. Community-Based Participatory Research (CBPR) is an approach that can be used to include community input to improve water management strategies. In the San Bernardino National Forest (SBNF) area in southern California, there are disadvantaged communities that can benefit from a CBPR study to increase water quality in the area. A geovisualization tool will …

Bird banding data showed widespread movement of waterfowl within the Atlantic Flyway and between neighboring flyways and northern breeding grounds.

New Multimedia Resources For Ecological Resilience Education In Modern University Classrooms, Katharine F. E. Hogan, Julie A. Fowler, Conor D. Barnes, Alison K. Ludwig, Dominic J. Cristiano, Daniel Morales, Rubi Quiñones, Dirac L. Twidwell Jr, Jenny Dauer

School of Natural Resources: Faculty Publications

Solutions to global problems such as climate change and biodiversity loss require educational frameworks and accompanying teaching resources that are theory-based, interdisciplinary, and accessible to broad undergraduate and graduate student audiences. Ecological resilience theory (ERT) is a framework with established interdisciplinary application to complex global problems, but despite an emphasis on the utility of resilience in national higher education frameworks, we found that many current ecology textbooks incorporate multiple definitions and highly variable amounts of discussion on core resilience concepts. To facilitate the use of innovative teaching resources in ERT in universities, this paper describes four free multimedia tools and …

A Spatial Assessment Of Impacts To The Flats Fishery By Recreational Boating In The Florida Keys National Marine Sanctuary, Kristin Anderson

All HCAS Student Capstones, Theses, and Dissertations

The recreational flats fishery in the Florida Keys is a significant component of the marine resource-based economy, exceeding $465 million (USD) in annual economic impact. Permit (Trachinotus falcatus), bonefish (Albula vulpes), and tarpon (Megalops atlanticus) are the three main species targeted by flat fishers. Those participating in this fishery generally practice catch-and-release angling therefore, the fishery is considered a more sustainable marine use compared to more traditional commercial fisheries. However, with population and tourism rising in South Florida, the fishery is increasingly threatened by habitat degradation and user conflicts. Ongoing revisions to the Florida …

Meeting U.S. Greenhouse Gas Emissions Goals With The International Air Pollution Provision Of The Clean Air Act, Mei Yuan, Alexander R. Barron, Noelle E. Selin, Paul D. Picciano, Lucy E. Metz, John M. Reilly, Henry D. Jacoby

Environmental Science and Policy: Faculty Publications

We explore economic, distributional and health consequences of U.S. greenhouse gas emissions objectives that could be achieved using Section 115 of the Clean Air Act (international air pollution), which has only recently received detailed legal analysis as a potential U.S. climate policy tool. Under it a national emissions target could be allocated among the states. This illustrative analysis considers 45% and 50% reductions of energy and industry-related CO2 emissions by 2030, below 2005 levels, via a model rule. Different approaches (based on legal precedent) for the interstate allocation are considered, along with alternative rates of technology improvement. The detail needed …

Individual Trophic Niche Specialization In American Beaver (Castor Canadensis), Jimmy Taylor, Robert Francis, Scott Rush, Bronson Strickland, Guiming Wang

United States Department of Agriculture Wildlife Services: Staff Publications

The American beaver (Castor canadensis) has been described as a choosy generalist at the species/population scale, yet observational studies have shown little variation in diet among individuals. We compared isotopic values of δ¹³C or δ¹⁵N taken from hair of 32 beaver, representing seven colonies in northern Alabama, USA to determine 1) if colonies of beaver show overlap in isotopic niche width as a result of the similar use of food resources and 2) if individual trophic niche specialization occurs within colonies. Total Trophic Niche Width varied across the wetland with the widest being twice …

Retrospective Comparisons Of Competing Demographic Models Give Clarity From “Messy” Management On A Scottish Grouse Moor, Larkin A. Powell, Nicholas J. Aebischer, Sonja C. Ludwig, David Baines

School of Natural Resources: Faculty Publications

Retrospective comparison of predictive models that describe competing hypotheses regarding system function can shed light on regulatory mechanisms within the framework of adaptive resource management. We applied this approach to a 28-year study of red grouse (Lagopus lagopus scotica) in Scotland, with the aims of reducing uncertainty regarding important drivers of grouse population dynamics, and of evaluating the efficacy of using seasonal versus annual model assessments. We developed three sets of models that predicted pre-breeding and post-breeding grouse density, matching the timing of grouse counts on the ground. We updated conditions and management through time in the spirit …

Editorial: Special Issue “Innovative Techniques And Approaches In The Control And Prevention Of Rabies Virus”, Amy T. Gilbert, Ryan M. Wallace, Charles E. Rupprecht

United States Department of Agriculture Wildlife Services: Staff Publications

Rabies is an ancient lethal scourge that has plagued humankind for centuries. Globally, 60,000 human deaths are estimated to occur each year from rabies virus (RABV) transmission in domestic dogs, mostly affecting children. While rabies is recognized as a neglected disease, there is cause for optimism in the context of growing global recognition, collaboration and commitment to advance a tripartite agenda to eliminate human deaths transmitted from rabid dogs by 2030, also known as “Zero By Thirty” (ZBT). Nevertheless, the ZBT goal must also confront competing challenge(s) of tracking and mitigating human morbidity and mortality during a global pandemic caused …

Think Of The Future: From Nonrenewable To Sustainable, Froyzee Rey Eduard Armena

Symposium of Student Scholars

Abstract

When seawater evaporates, it becomes rainwater that you can store and use later on. The resources available on earth are immeasurable, yet it takes so much time for it to replenish its usable state, just like the ocean. When I drive through cities, I’m always in awe of being constantly reminded how the human race has progressed. The rate at which we progress concerns me, do we have enough power to fuel the future? Are the resources we can tap in from support the amount of research we do? This research aims to assess our energy reserves that seem …

Can We Use Antipredator Behavior Theory To Predict Wildlife Responses To High-Speed Vehicles?, Ryan B. Lunn, Bradley Blackwell, Travis L. Devault, Esteban Fernández-Juricic

United States Department of Agriculture Wildlife Services: Staff Publications

Animals seem to rely on antipredator behavior to avoid vehicle collisions. There is an extensive body of antipredator behavior theory that have been used to predict the distance/time animals should escape from predators. These models have also been used to guide empirical research on escape behavior from vehicles. However, little is known as to whether antipredator behavior models are appropriate to apply to an approaching high-speed vehicle scenario. We addressed this gap by (a) providing an overview of the main hypotheses and predictions of different antipredator behavior models via a literature review, (b) exploring whether these models can generate quantitative …

Evaluating Gizzard Shad Dorosoma Cepedianum Populations In Two Kentucky Reservoirs Recently Invaded With Silver Carp Hypopthalmichthys Molitrix, Nathan Klein

Scholars Week

Gizzard Shad Dorosoma cepedianum are an ecologically important fish species found in many reservoirs throughout the southeastern United States such as Kentucky Lake and Lake Barkley. One current challenge that Gizzard Shad may face in these two reservoirs is competition with the invasive Silver Carp Hypophthalmichthys molitrix. However, quantifying the impacts of this competition may be difficult because of limited baseline population data for Gizzard Shad in these two reservoirs. The objective of this study is to describe size structure, condition, age, growth, mortality, and spawning potential of these two populations. Gizzard Shad were collected by boat electrofishing and …

Maize Leaf Appearance Rates: A Synthesis From The United States Corn Belt, Caio L. Dos Santos, Lori J. Abendroth, Jeffrey A. Coulter, Emerson D. Nafziger, Andrew E. Suyker, Jianming Yu, Patrick S. Schnable, Sotirios V. Archontoulis

School of Natural Resources: Faculty Publications

The relationship between collared leaf number and growing degree days (GDD) is crucial for predicting maize phenology. Biophysical crop models convert GDD accumulation to leaf numbers by using a constant parameter termed phyllochron (°C-day leaf⁻¹) or leaf appearance rate (LAR; leaf ^oC-day⁻¹). However, such important parameter values are rarely estimated for modern maize hybrids. To fill this gap, we sourced and analyzed experimental datasets from the United States Corn Belt with the objective to (i) determine phyllochron values for two types of models: linear (1-parameter) and bilinear (3-parameters; phase I and II phyllochron, and transition …
