Assessment Of Salt Marsh Change On Assateague Island National Seashore Between 1962 And 2016, Anthony Campbell, Yeqiao Wang

Natural Resources Science Faculty Publications

Salt marshes provide extensive ecosystem services, including high biodiversity, denitrification, and wave attenuation. In the mid-Atlantic, sea level rise is predicted to affect salt marsh ecosystems severely. This study mapped the entirety of Assateague Island with Very High Resolution satellite imagery and object-based methods to determine an accurate salt marsh baseline for change analysis. Topobathymetric light detection and ranging was used to map the salt marsh and model expected tidal effects. The satellite imagery, collected in 2016 and classified at two hierarchical thematic schemes, were compared to determine appropriate thematic richness. Change analysis between this 2016 map and both a …

Potential For Managed Aquifer Recharge To Enhance Fish Habitat In A Regulated River, Robert W. Van Kirk, Bryce A. Contor, Christina N. Morrisett, Sarah E. Null, Ashly S. Loibman

Watershed Sciences Faculty Publications

Managed aquifer recharge (MAR) is typically used to enhance the agricultural water supply but may also be promising to maintain summer streamflows and temperatures for cold-water fish. An existing aquifer model, water temperature data, and analysis of water administration were used to assess potential benefits of MAR to cold-water fisheries in Idaho’s Snake River. This highly-regulated river supports irrigated agriculture worth US $10 billion and recreational trout fisheries worth $100 million. The assessment focused on the Henry’s Fork Snake River, which receives groundwater from recharge incidental to irrigation and from MAR operations 8 km from the river, addressing (1) the …

Extensive Marine Anoxia Associated With The Late Devonian Hangenberg Crisis, Feifei Zhang, Tais W. Dahl, Timothy M. Lenton, Genming Luo, Shu Zhong Shen, Thomas J. Algeo, Noah Planavsky, Jiangsi Liu, Ying Cui, Wenkun Qie, Stephen J. Romaniello, Ariel D. Anbar

Department of Earth and Environmental Studies Faculty Scholarship and Creative Works

The global Hangenberg Crisis near the Devonian-Carboniferous boundary (DCB) represents one of the major Phanerozoic mass extinction events, which shaped the roots of modern vertebrate biodiversity. Marine anoxia has been cited as the proximate kill mechanism for this event. However, the detailed timing, duration, and extent of global marine redox chemistry changes across this critical interval remain controversial because most of the studies to date only constrain changes in local or regional redox chemistry. Thus, opinions on the significance of anoxia as a kill mechanism are variable—from anoxia being a primary driver to being relatively unimportant. In this study, we …

Differential Cytotoxicity Induced By Transition Metal Oxide Nanoparticles Is A Function Of Cell Killing And Suppression Of Cell Proliferation, Larry M. Tolliver, Natalie J. Holl, Fang Yao Stephen Hou, Han-Jung Lee, Melissa H. Cambre, Yue-Wern Huang

Biological Sciences Faculty Research & Creative Works

The application of nanoparticles (NPs) in industry is on the rise, along with the potential for human exposure. While the toxicity of microscale equivalents has been studied, nanoscale materials exhibit different properties and bodily uptake, which limits the prediction ability of microscale models. Here, we examine the cytotoxicity of seven transition metal oxide NPs in the fourth period of the periodic table of the chemical elements. We hypothesized that NP-mediated cytotoxicity is a function of cell killing and suppression of cell proliferation. To test our hypothesis, transition metal oxide NPs were tested in a human lung cancer cell model (A549). …

Recharge Seasonality Based On Stable Isotopes: Nongrowing Season Bias Altered By Irrigation In Nebraska, Mikaela Cherry, Troy E. Gilmore, Aaron R. Mittelstet, Didier Gastmans, Vinicius Santos, John Gates

School of Natural Resources: Faculty Publications

The sustainability of groundwater resources for agricultural and domestic use is dependent on both the groundwater recharge rate and groundwater quality. The main purpose of this study was to improve understanding of the timing, or seasonality, of groundwater recharge through the use of stable isotopes. Based on 659 groundwater samples collected from aquifers underlying Natural Resources Districts in Nebraska, the isotopic composition of groundwater (δ 2H, δ 18O) was compared to that of precipitation by (a) mapping the isotopic composition of groundwater samples and (b) mapping a seasonality index for groundwater. Results suggest that for the majority of the state, …

Tackling Regional Climate Change Impacts And Food Security Issues: A Critical Analysis Across Asean, Pif, And Saarc, Md. Saidul Islam, Edson Kieu

Research Collection Lee Kong Chian School Of Business

Climate change and food security issues are multi-faceted and transcend across national boundaries. Therefore, this paper begins with the premise that regional organizations are optimally positioned to address climate change and food security issues while actively engaging global partners to slow down or reverse current trajectories. However, the potential of regional organizations to play a central role in mitigating these vital concerns has not been realized. In this paper, we focus on three regional organizations—the Association of Southeast Asian Nations (ASEAN), the Pacific Islands Forum (PIF), and the South Asian Association for Regional Cooperation (SAARC) and set out to investigate …

Cats And Conservationists: The Debate Over Who Owns The Outdoors, Dara M. Wald, Anna L. Peterson

Purdue University Press Book Previews

Cats and Conservationists is the first multidisciplinary analysis of the heated debate about free-roaming cats. The debate pits conservationists against cat lovers, who disagree both on the ecological damage caused by the cats and the best way to manage them. An impassioned and spirited conflict, it also sheds light on larger questions about how we interpret science, incorporate diverse perspectives, and balance competing values in order to encourage constructive dialogue on contentious social and environmental issues.

On one side of the cat debate stand many environmentalists, especially birders and conservation organizations, who believe that outdoor cats seriously threaten native wildlife. …

Geographies Of Transition—From Topical Concerns To Theoretical Engagement: A Commentary On The Transitions Research Agenda, Christian Binz, Lars Coenen, James T. Murphy, Bernhard Truffer

Geography

This viewpoint takes stock with the ‘geography of sustainability transitions’ (GOST) as it is presented in the transitions research agenda. GOST has been a relatively recent addition to transition theorizing, addressing the need for greater sensitivity and attention to the scales, spatialities, and context-specific factors that shape transitions. In our view, the agenda represents a rather narrow perspective on GOST, which is geared to two empirical themes, namely urban transitions and transitions in developing countries. While these are relevant and topical issues, the section lacks sufficient acknowledgement of the increasing engagement of geographers with transitions studies and the theoretical approaches …

Ecojustice, Religious Folklife And A Sound Ecology, Jeff Todd Titon

Yale Journal of Music & Religion

Folk, traditional, and indigenous ecological knowledges have a significant role to play in ecojustice. A case study in the traditional ecological knowledge among one of the religious communities with whom I have spent several decades illustrates how they embody the main principle and three fields of an ecological rationality: the community of inter-related beings; the ways the beings participate in that community or place; and the relations of nature and the nonhuman world to humans and human nature. Ecological rationality stands in contrast to economic rationality, a branch of instrumental reason exemplified by what economists call rational choice theory. An …

Salt Marsh Monitoring Along The Mid-Atlantic Coast By Google Earth Engine Enabled Time Series, Anthony D. Campbell, Yeqiao Wang

Natural Resources Science Faculty Publications

Salt marshes provide a bulwark against sea-level rise (SLR), an interface between aquatic and terrestrial habitats, important nursery grounds for many species, a buffer against extreme storm impacts, and vast blue carbon repositories. However, salt marshes are at risk of loss from a variety of stressors such as SLR, nutrient enrichment, sediment deficits, herbivory, and anthropogenic disturbances. Determining the dynamics of salt marsh change with remote sensing requires high temporal resolution due to the spectral variability caused by disturbance, tides, and seasonality. Time series analysis of salt marshes can broaden our understanding of these changing environments. This study analyzed aboveground …

Crustal Composition And Moho Variations Of The Central And Eastern United States: Improving Resolutionand Geologic Interpretation Of Earthscope Usarray Seismic Images Using Gravity, H. L. Zhang, D. Ravat, Anthony R. Lowry

Geosciences Faculty Publications

EarthScope's USArray Transportable Array has shortcomings for the purpose of interpreting geologic features of wavelengths less than the Transportable Array station spacing, but these can be overcome by using higher spatial resolution gravity data. In this study, we exploit USArray receiver functions to reduce nonuniqueness in the interpretation of gravity anomalies. We model gravity anomalies from previously derived density variations of sedimentary basins, crustal V_p/V_s variation, Moho variation, and upper mantle density variation derived from body wave imaging informed by surface wave tomography to estimate V_p/V_s. Although average densities and density contrasts for …

Estimation Of Available Epinephrine Dose In Expired And Discolored Autoinjectors Via Quantitative Smartphone Imaging, Amirus Saleheen, Bill M. Campbell, Rebecca A. Prosser, Christopher A. Baker

United States National Park Service: Publications

Epinephrine autoinjectors (EAIs) are important first aid medications for treating anaphylaxis. A 10-fold price increase over the past 12 years and evidence that expired EAIs may still contain significant doses of available epinephrine have motivated interest in the efficacy of expired EAIs as treatments of last resort. Degradation of expired EAIs, which can be caused by improper storage conditions, results in various degrees of discoloration of the epinephrine solution. Previous studies have determined that significant epinephrine remains available in expired EAIs, but these have only considered EAIs that show no discoloration. Here, we investigate the potential for colorimetric estimation of …
