Road Network Analyses Elucidate Hidden Costs Of Road Flooding Under Accelerating Sea Level Rise, Molly Mitchell, Jessica Hendricks, Daniel Schatt

VIMS Articles

Introduction: As sea level rises and coastal communities simultaneously grow, road flooding has the potential to significantly disrupt travel along road networks and make houses, businesses, and critical facilities difficult to reach. The impacts of tidal and storm surge flooding on roadways present challenging social and economic considerations for all coastal jurisdictions. Maintenance, public and private accessibility, evacuation routes, emergency services are just a few of the common themes local governments are beginning to address for low-lying roadways currently known to flood. Continuation of these services allows a community to thrive, to maintain or increase its tax base, and to …

How The Covid-19 Pandemic Changed Patterns Of Green Infrastructure Use: A Scoping Review, Amanda Bristowe, Megan Heckert

This scoping review seeks to address whether the COVID-19 pandemic affected the use of GI, specifically the ways in which the pandemic altered visitation patterns and the frequency of the use of GI. This review identifies studies that explore the relationship between the COVID-19 pandemic and GI use and assesses whether the pandemic has altered the use of GI, including whether …

Gloria - A Globally Representative Hyperspectral In Situ Dataset For Optical Sensing Of Water Quality, Moritz K. Lehmann

School of Natural Resources: Faculty Publications

The development of algorithms for remote sensing of water quality (RSWQ) requires a large amount of in situ data to account for the bio-geo-optical diversity of inland and coastal waters. The GLObal Reflectance community dataset for Imaging and optical sensing of Aquatic environments (GLORIA) includes 7,572 curated hyperspectral remote sensing reflectance measurements at 1nm intervals within the 350 to 900nm wavelength range. In addition, at least one co-located water quality measurement of chlorophyll α, total suspended solids, absorption by dissolved substances, and Secchi depth, is provided. The data were contributed by researchers affiliated with 59 institutions worldwide and come from …

The Ecology Of Human-Caused Mortality For A Protected Large Carnivore, John F. Benson, Kyle D. Dougherty, Paul Beier, Walter M. Boyce, Bogdan Cristescu, Daniel J. Gammons, David K. Garcelon, J. Mark Higley, Quinton E. Martins, Anna C. Nisi, Seth P. D. Riley, Jeff A. Sikich, Thomas R. Stephenson, T. Winston Vickers, Greta M. Wengert, Christopher C. Wilmers, Heiko U. Wittmer, Justin A. Dellinger

School of Natural Resources: Faculty Publications

Mitigating human-caused mortality for large carnivores is a pressing global challenge for wildlife conservation. However, mortality is almost exclusively studied at local (within-population) scales creating a mismatch between our understanding of risk and the spatial extent most relevant to conservation and management of wide-ranging species. Here, we quantified mortality for 590 radio-collared mountain lions statewide across their distribution in California to identify drivers of human-caused mortality and investigate whether human-caused mortality is additive or compensatory. Human-caused mortality, primarily from conflict management and vehicles, exceeded natural mortality despite mountain lions being protected from hunting. Our data indicate that human-caused mortality is …

Prioritizing The Protection And Creation Of Natural And Naturebased Features For Coastal Resilience Using A Gis-Based Ranking Framework – An Exportable Approach, Jessica Hendricks, Pamela Mason, Julie Herman, Carl Hershner

VIMS Articles

Increasing the preservation and creation of natural and nature-based features (NNBF), like wetlands, living shorelines, beaches, dunes and other natural features to improve community resilience in the face of increasing coastal flooding may be achieved by highlighting the locally relevant benefits that these features can provide. Here we present a novel application of the least-cost geospatial modeling approach to generate inundation pathways that highlight landscape connections between NNBF and vulnerable infrastructure. Inundation pathways are then used to inform a ranking framework that assesses NNBF based on their provision of benefits and services to vulnerable infrastructure and for the broader community …

Occupancy And Abundance Of A West African Mangabey Species (Cercocebus Atys Audebert, 1797) In Forest Patch Habitat, Kellie Laity, April Conway, Sonia M. Hernandez, John P. Carroll, Dessalegn Ejigu

School of Natural Resources: Faculty Publications

Sooty mangabeys are Old World primates from the Upper Guinea Rainforests of West Africa. They suffer from habitat degradation due to deforestation and hunting for the bush-meat trade. Tiwai Island and adjacent small islands are a small protected area surrounded by the Moa River that is known for its high diversity of primate species. We evaluated the occupancy and abundance of sooty mangabeys on Tiwai Island and the surrounding islands using camera traps during 2008–2011. Over two seasons, we obtained a naïve occupancy rate of 0.77 for Tiwai Island but only 0.19 for surrounding smaller islands. We used Abundance-Induced Heterogeneity …

Drought Stress Prediction And Propagation Using Time Series Modeling On Multimodal Plant Image Sequences, Sruti Das Choudhury, Sinjoy Saha, Ashok Samal, Anastasios Mazis, Tala Awada

School of Natural Resources: Faculty Publications

The paper introduces two novel algorithms for predicting and propagating drought stress in plants using image sequences captured by cameras in two modalities, i.e., visible light and hyperspectral. The first algorithm, VisStressPredict, computes a time series of holistic phenotypes, e.g., height, biomass, and size, by analyzing image sequences captured by a visible light camera at discrete time intervals and then adapts dynamic time warping (DTW), a technique for measuring similarity between temporal sequences for dynamic phenotypic analysis, to predict the onset of drought stress. The second algorithm, HyperStressPropagateNet, leverages a deep neural network for temporal stress propagation using hyperspectral imagery. …

Rhino Conservation In Africa, Andrew N. Rowan

WellBeing News

The recovery of white rhinos from a small population of 20 animals in 1895 to tens of thousands today is a major conservation success story, but we are again facing a rapid decline in the numbers of both species of African rhinoceros due mainly to poaching. Demand for rhino horn, mainly from the Far East, has led to an epidemic of poaching. The healthy population of white rhinos in South Africa’s Kruger National Park has fallen from just under 12,000 individuals in 2010 to around 2,200 in 2022. At the current rate of decline, white rhinos will be eliminated from …

Sexual Selection As A Tool To Improve Student Reasoning Of Evolution, Sarah K. Spier, Joseph Dauer

School of Natural Resources: Faculty Publications

There is an emphasis on survival-based selection in biology education that can allow students to neglect other important evolutionary components, such as sexual selection, reproduction, and inheritance. Student understanding of the role of reproduction in evolution is as important as student understanding of the role of survival. Limiting instruction to survival- based scenarios (e.g., effect of food on Galapagos finch beak shape) may not provide students with enough context to guide them to complete evolutionary reasoning. Different selection forces can work in concert or oppose one another, and sexual selection can lead to the selection of trait variants that are …

Trophically Integrated Ecometric Models As Tools For Demonstrating Spatial And Temporal Functional Changes In Mammal Communities, Rachel A. Short, Jenny L. Mcguire, P. David Polly, A. Michelle Lawing

Natural Resource Management Faculty Publications

We are in a modern biodiversity crisis that will restructure community compositions and ecological functions globally. Large mammals, important contributors to ecosystem function, have been affected directly by purposeful extermination and indirectly by climate and land-use changes, yet functional turnover is rarely assessed on a global scale using metrics based on functional traits. Using ecometrics, the study of functional trait distributions and functional turnover, we examine the relationship between vegetation cover and locomotor traits for artiodactyl and carnivoran communities. We show that the ability to detect a functional relationship is strengthened when locomotor traits of both primary consumers (artiodactyls, n …

Fossil Fuel Divestment In U.S. Higher Education: Endowment Dependence And Temporal Dynamics, Alexander R. Barron, Rachel C. Venator, Ella V.H. Carlson, Jane K. Andrews, Junwen Ding, David Deswert

Environmental Science and Policy: Faculty Publications

Since 2012, students and others have pushed U.S. Higher Education Institutions (HEIs) to divest their endowments from fossil fuel producing industries. In the past decade, fossil fuel divestment has become the fastest growing divestment movement in history, with over 140 U.S. HEIs announcing divestment commitments. We conduct a quantitative analysis of the three phases of U.S. 4-year HEI divestment announcements (as well as rejections of divestment) to better understand the dynamics. Announcements began (2012-2017) with a number of schools divesting, followed by a second phase where new divestment announcements slowed. The current phase, which began around 2019, shows a renewed …

An Evaluation Of Avian Influenza Virus Whole-Genome Sequencing Approaches Using Nanopore Technology, Hon S. Ip, Sarah Uhm, Mary Lea Killian, Mia K. Torchetti

United States Department of Agriculture Wildlife Services: Staff Publications

As exemplified by the global response to the SARS-CoV-2 pandemic, whole-genome sequencing played an important role in monitoring the evolution of novel viral variants and provided guidance on potential antiviral treatments. The recent rapid and extensive introduction and spread of highly pathogenic avian influenza virus in Europe, North America, and elsewhere raises the need for similarly rapid sequencing to aid in appropriate response and mitigation activities. To facilitate this objective, we investigate a next-generation sequencing platform that uses a portable nanopore sequencing device to generate and present data in real time. This platform offers the potential to extend in-house sequencing …

Assessing Ecosystem Health Through Contaminants In The Tijuana River National Estuarine Research Reserve, Nancy Torres

Theses

Although the Tijuana River Estuary (TRE) remains the largest, most-intact coastal wetland in Southern California, it has a history of major changes, much of this related to its location immediately north of the US / Mexico Border. One of the primary challenges is cross-border flows from the rapidly growing city of Tijuana, Baja California, Mexico, and the delivery of wastewater, debris, and sediment to sensitive coastal wetland ecosystems. There is a need to more fully investigate these environmental changes to assess the ecosystem health of the Tijuana River Estuary over time, especially related to pollution impacts. This can inform an …

Development Of A Benchmark Eddy Flux Evapotranspiration Dataset For Evaluation Of Satellite-Driven Evapotranspiration Models Over The Conus, John M. Volk, Justin Huntington, Forrest S.

School of Natural Resources: Faculty Publications

A large sample of ground-based evapotranspiration (ET) measurements made in the United States, primarily from eddy covariance systems, were post-processed to produce a benchmark ET dataset. The dataset was produced primarily to support the intercomparison and evaluation of the OpenET satellite-based remote sensing ET (RSET) models and could also be used to evaluate ET data from other models and approaches. OpenET is a web-based service that makes field-delineated and pixel-level ET estimates from well-established RSET models readily available to water managers, agricultural producers, and the public. The benchmark dataset is composed of flux and meteorological data from a variety of …

Regenerative Agriculture - A Literature Review On The Practices And Mechanisms Used To Improve Soil Health, Ravjit Khangura, David Ferris, Cameron Wagg, Jamie Bowyer

Natural Resources Research Articles

Conventional farming practices can lead to soil degradation and a decline in productivity. Regenerative agriculture (RA) is purported by advocates as a solution to these issues that focuses on soil health and carbon sequestration. The fundamental principles of RA are to keep the soil covered, minimise soil disturbance, preserve living roots in the soil year round, increase species diversity, integrate livestock, and limit or eliminate the use of synthetic compounds (such as herbicides and fertilisers). The overall objectives are to rejuvenate the soil and land and provide environmental, economic, and social benefits to the wider community. Despite the purported benefits …

Diversity, Distribution, And Methodological Considerations Of Haemosporidian Infections Among Galliformes In Alaska, Faith De Amaral, Robert E. Wilson, Sarah A. Sonsthagen, Ravinder Sehgal

School of Natural Resources: Faculty Publications

Using samples spanning 10-degrees of latitude in Alaska, we provide the first comparative assessment of avian haemosporidia distribution of Arctic Alaska with subarctic host populations for four species of grouse and three species of ptarmigan (Galliformes). We found a high overall prevalence for at least one haemospordian genus (88%; N = 351/400), with spruce grouse (Canachites canadensis) showing the highest prevalence (100%; N = 54/ 54). Haemoproteus and Plasmodium lineages were only observed within grouse, while Leucocytozoon species were found within both grouse and ptarmigan. Further, different Leucocytozoon lineages were obtained from blood and tissue samples from the …

United States Department of Agriculture Wildlife Services: Staff Publications

Burmese pythons (Python molurus bivittatus) are native to southeastern Asia, however, there is an established invasive population inhabiting much of southern Florida throughout the Greater Everglades Ecosystem. Pythons have severely impacted native species and ecosystems in Florida and represent one of the most intractable invasive-species management issues across the globe. The difficulty stems from a unique combination of inaccessible habitat and the cryptic and resilient nature of pythons that thrive in the subtropical environment of southern Florida, rendering them extremely challenging to detect. Here we provide a comprehensive review and synthesis of the science relevant to managing invasive …

National Development And The Sustainability Of Mining In The Atacama Desert, Chile, Dakota Soleil Osgood

Capstone Collection

As climate change continues to intensify on a global scale, efforts have been made to implement renewable energies and progressive technologies. These tools are critical in the shift towards a more sustainable practice, and yet analysis of localized impacts from the development of these mechanisms is inadequate. Chile has been and continues to be a leading country in mineral extraction, with an economic history founded in the mining industry. The establishment of mining in Chile as a progressive tool has aided the social and economic development of the nation. Consequences of mining extraction, however, include intensive environmental degradation, human rights …

Habitat Fragmentation Reduces Survival And Drives Source–Sink Dynamics For A Large Carnivore, Anna C. Nisi, John F. Benson, Richard King, Christopher C. Wilmers

School of Natural Resources: Faculty Publications

Rigorous understanding of how environmental conditions impact population dynamics is essential for species conservation, especially in mixed-use landscapes where source–sink dynamics may be at play. Conservation of large carnivore populations in fragmented, human-dominated landscapes is critical for their long-term persistence. However, living in human-dominated landscapes comes with myriad costs, including direct anthropogenic mortality and sublethal energetic costs. How these costs impact individual fitness and population dynamics are not fully understood, partly due to the difficulty in collecting long-term demographic data for these species. Here, we analyzed an 11-year dataset on puma (Puma concolor) space use, mortality, and reproduction …

This review provides an overview of the various programs and funding mechanisms that currently exist within Utah, describes how and to what extent they are funded, outlines how they support outdoor recreation and tourism, and highlights opportunities where the state can strategically refine or build upon them.

The Future Of Pandemics: Land Use Controls As Means Of Preventing Zoonotic Disease, Bailey Andree

Pace International Law Review

Zoonotic diseases are increasing in frequency as climate change worsens around the world, with the recent COVID-19 pandemic highlighting the inadequate mechanisms in place to counteract disease spread. This article reviews various zoonotic diseases and their patterns of spread, highlighting land use change as the key driver of disease to demonstrate the need for legal intervention. International land use law is a little-developed subsect of environmental law that holds the key to combating this disease spread, and this article proposes solutions through this legal lens. Land use techniques which may be used to combat disease spread include conservation laws, setback …

Boundary Spanning In The Context Of Stakeholder Engagement In Collaborative Water Management, Mark E. Burbach, Weston M. Eaton, Jodi L. Delozier

School of Natural Resources: Faculty Publications

Boundary spanners are individuals able to reach across organizational borders to build relationships and interconnections to help better manage complex problems. What is not clear, however, are the skills that allow boundary spanners to cross diverse scales, sectors, and organizations. To address this gap, we use a qualitative case study approach to examine evidence for how boundary spanning skills are implemented in the context of stakeholder engagement for addressing water challenges in agricultural settings. We employ a hybrid deductive-inductive thematic analysis approach to examine interview data collected with 25 stakeholder participants as well as direct observation of engagement behavior. Interview …

Climate Change And The Law Of National Security Adaptation, Mark P. Nevitt

Faculty Articles

The Department of Defense (DoD) is the largest employer in the world, owns and operates an enormous global real estate portfolio, and emits more Greenhouse Gases (GHGs) than many nations. Entrusted with the national security, the DoD is now threatened by a new enemy—climate change. Climate change imperils national security infrastructure while undermining the military’s capacity to respond to climate-driven disasters at home and abroad. However, legal scholarship has yet to address what I call “the law of national security adaptation” and related questions. For example, how do environmental and climate change laws apply to the U.S. military? What laws …

Role Of Social Determinants Of Health In Differential Respiratory Exposure And Health Outcomes Among Children, Jagadeesh Puvvula, Jill A. Poole, Yeongjin Gwon, Eleanor G. Rogan, Jesse E. Bell

School of Natural Resources: Faculty Publications

Background Attributes defining the Social Determinants of Health (SDoH) are associated with disproportionate exposures to environmental hazards and differential health outcomes among communities. The dynamics between SDoH, disproportionate environmental exposures, and differential health outcomes are often specific to micro-geographic areas.

Methods This study focused on children less than 20 years of age who lived in Douglas County, Nebraska, during 2016–2019. To assess the role of SDoH in differential exposures, we evaluated the association between SDoH metrics and criteria pollutant concentrations and the association between SDoH and pediatric asthma exacerbations to quantify the role of SDoH in differential pediatric asthma outcomes. …

Panarchy Theory For Convergence, Shana M. Sundstrom, David G. Angeler, Jesse Bell, Michael J. Hayes, Jennifer Hodbod, Babak Jalalzadeh‑Fard, Rezaul Mahmood, Elizabeth Vanwormer, Craig R. Allen

School of Natural Resources: Faculty Publications

Coping with surprise and uncertainty resulting from the emergence of undesired and unexpected novelty or the sudden reorganization of systems at multiple spatiotemporal scales requires both a scientific process that can incorporate diverse expertise and viewpoints, and a scientific framework that can account for the structure and dynamics of interacting social-ecological systems (SES) and the inherent uncertainty of what might emerge in the future. We argue that combining a convergence scientific process with a panarchy framework provides a pathway for improving our understanding of, and response to, emergence. Emergent phenomena are often unexpected (e.g., pandemics, regime shifts) and can be …
