School of Natural Resources: Faculty Publications

Climate change is known to increase the frequency and intensity of hot days (daily maximum temperature ≥30°C), both globally and locally. Exposure to extreme heat is associated with numerous adverse human health outcomes. This study estimated the burden of heat-related illness (HRI) attributable to anthropogenic climate change in North Carolina physiographic divisions (Coastal and Piedmont) during the summer months from 2011 to 2016. Additionally, assuming intermediate and high greenhouse gas emission scenarios, future HRI morbidity burden attributable to climate change was estimated. The association between daily maximum temperature and the rate of HRI was evaluated using the Generalized Additive Model. …

Intensifying permafrost thaw alters carbon cycling by mobilizing large amounts of terrestrial substrate into aquatic ecosystems. Yet, few studies have measured aquatic carbon fluxes and constrained drivers of ecosystem carbon balance across heterogeneous Arctic landscapes. Here, we characterized hydrochemical and landscape controls on fluvial carbon cycling, quantified fluvial carbon fluxes, and estimated fluvial contributions to ecosystem carbon balance across 33 watersheds in four ecoregions in the continuous permafrost zone of the western Canadian Arctic: unglaciated uplands, ice-rich moraine, and organic-rich lowlands and till plains. Major ions, stable isotopes, and carbon speciation and fluxes revealed patterns in carbon cycling across ecoregions …

Environmental Justice Mapping In The U.S. Pacific Island Territory Of Guam, Ben Rocha

Master of Science in Environmental Sciences and Management Projects

Academics, regulators, and the public currently use geospatial analysis tools to identify locations that may be candidates for further environmental justice review in the continental United States (U.S.). However, current environmental justice geospatial analysis tools overlook a small but significant portion of the U.S. - the U.S. Pacific Islands. This study analyzes environmental justice within the U.S. Territory of Guam using existing geospatial analysis methods and publicly available environmental, climate, and socio-economic data to: (1) Spatially map relevant demographic and environmental data and (2) determine the correlation, if any, between the exposure to environmental hazards and the socio-economic status of …

Sea Level Rise Estimation On The Pacific Coast From Southern California To Vancouver Island, Xiaoxing He, Jean-Philippe Montillet, Rui Fernandes, Timothy I. Melbourne, Weiping Jiang, Zhengkai Huang

Geological Sciences Faculty Scholarship

Previous studies have estimated the sea level rise (SLR) at various locations on the west coast of the USA and Vancouver Island in Canada. Here, we construct an entire SLR profile from Vancouver Island in the Pacific Northwest to San Diego in Southern California. First, we process global navigation satellite system (GNSS) measurements at 405 stations blanketing the whole coast to generate a profile of vertical land motion (VLM) known to bias century-long tide gauge (TG) measurements recording relative SLR (RSLR). We are then able to estimate the absolute SLR (ASLR) by correcting the SLR with the VLM. Our study …

The State Of Capacity Development Evaluation In Biodiversity Conservation And Natural Resource Management, Eleanor J. Sterling, Amanda Sigouin, Erin Betley, Jennifer Zavaleta Cheek, Jennifer N. Soloman, Kimberley Landrigan, Ana L. Porzecanski, Et. Al.

Natural Resource Management Faculty Publications

Capacity development is critical to long-term conservation success, yet we lack a robust and rigorous understanding of how well its effects are being evaluated. A comprehensive summary of who is monitoring and evaluating capacity development interventions, what is being evaluated and how, would help in the development of evidence-based guidance to inform design and implementation decisions for future capacity development interventions and evaluations of their effectiveness. We built an evidence map by reviewing peer-reviewed and grey literature published since 2000, to identify case studies evaluating capacity development interventions in biodiversity conservation and natural resource management. We used inductive and deductive …

Using Electrochemical Oxidation To Remove Pfas In Simulated Investigation-Derivedwaste (Idw): Laboratory And Pilot-Scale Experiments, Amy Yanagida, Elise Webb, Clifford E. Harris, Mark Christenson, Steven Comfort

School of Natural Resources: Faculty Publications

Repeated use of aqueous firefighting foams at military aircraft training centers has contaminated groundwater with per and polyfluorinated alkyl substances (PFAS). To delineate the extent of PFAS contamination, numerous site investigations have occurred, which have generated large quantities of investigation-derived wastes (IDW). The commonly used treatment of incinerating PFAS-tainted IDW is costly, and was recently suspended by the Department of Defense. Given long-term IDW storage in warehouses is not sustainable, our objective was to use electrochemical oxidation to degrade PFAS in contaminated water and then scale the technology toward IDW treatment. This was accomplished by conducting a series of laboratory …

Participatory Science In Boston Harbor: Bridging Research And Outreach, Anne E. O'Connell

Graduate Masters Theses

Participatory science programs are becoming effective mechanisms to provide members of the public opportunities to be involved in scientific research worldwide. In the city of Boston, coastal resilience research is of particular interest to researchers, policy makers, and members of the public due to the threat of up to two meters of sea level rise by the year 2100. As part of the outreach and education initiative at the Stone Living Lab, community members were trained to use the Emery method of beach profiling and conducted measurements at twelve different sites around Boston harbor. The sites were visited during the …

We conducted a range-wide investigation of the dynamics of site-level reproductive rate of northern spotted owls using survey data from 11 study areas across the subspecies geographic range collected during 1993–2018. Our analytical approach accounted for imperfect detection of owl pairs and misclassification of successful reproduction (i.e., at least one young fledged) and contributed further insights into northern spotted owl population ecology and dynamics. Both nondetection and state misclassification were important, especially because factors affecting these sources of error also affected focal ecological parameters. Annual probabilities of site occupancy were greatest at sites with successful reproduction in the previous year …

Study Of Constitutive Model Of Frozen Sandstone Damage Based On Weibull Distribution, Yi Ming, Zhao Tao, Ma Feifei, Wang Lei, Yuan Chao

Coal Geology & Exploration

Abstract: The deformation and destruction characteristics of frozen rock is a basic mechanical problem encountered during the construction using the freezing method. Under the action of load, the mechanical characteristics and deformation characteristics are greatly different for the rock with different freezing temperatures, which significantly affects the safety and stability of the freezing wall. Therefore, the study of the damage constitutive relation of the frozen rock is significant for instructing the freezing method design and construction. In order to analyze the whole process of the frozen rock deformation and destruction under load action, the Weibull distribution was adopted to describe …

Collateral Damage From Agricultural Netting To Open-Country Bird Populations In Thailand, Rongrong Angkaew, Philip D. Round, Dusit Ngoprasert, Larkin A. Powell

School of Natural Resources: Faculty Publications

Nets are used across a wide variety of food production landscapes to control avian pests typically resulting in deaths of entangled birds. However, the impact of nets on bird populations is a human–wildlife conflict that remains mostly unquantified. Here, we examined the scale of netting in the central plains of Thailand, a region dominated by ricefields, among which aquaculture ponds are increasingly interspersed. Nets/exclusion types, number of individual birds and species caught were recorded on 1312 road-survey transects (2-km length × 0.4-km width). We also interviewed 104 local farmers. The transect sampling took place in late- September 2020, and from …

Yankees In The Indian Ocean : American Commerce And Whaling, 1786–1860, Jane Hooper

Ohio University Press Open Access Books

The history of US imperialism remains incomplete without this consideration of long-overlooked nineteenth-century American commercial and whaling ventures in the Indian Ocean.

Yankees in the Indian Ocean shows how nineteenth-century American merchant and whaler activity in the Indian Ocean shaped the imperial future of the United States, influenced the region’s commerce, encouraged illegal slaving, and contributed to environmental degradation. For a brief time, Americans outnumbered other Western visitors to Mauritius, Madagascar, Zanzibar, and the East African littoral. In a relentless search for commodities and provisions, American whaleships landed at islands throughout the ocean and stripped them of resources. Yet Americans …

Seasonality Of Precipitation In The Southwestern United States During The Late Pleistocene Inferred From Stable Isotopes In Herbivore Tooth Enamel, Matthew J. Kohn, Kathleen B. Springer, Jeffrey S. Pigati, Linda M. Reynard, Amanda E. Drewicz, Justin Crevier, Eric Scott

United States Geological Survey: Staff Publications

The late Pleistocene was a climatically dynamic period, with abrupt shifts between cool-wet and warmdry conditions. Increased effective precipitation supported large pluvial lakes and long-lived spring ecosystems in valleys and basins throughout the western and southwestern U.S., but the source and seasonality of the increased precipitation are debated. Increases in the proportions of C₄/(C₄+ C₃) grasses in the diets of large grazers have been ascribed both to increases in summer precipitation and lower atmospheric CO₂ levels. Here we present stable carbon and oxygen isotope data from tooth enamel of late Pleistocene herbivores recovered …

Innovative Measure On Achieving Common Prosperity: Carbon Transfer Payment, Peili Lu, Lanling Peng, Jiaqi Shen, Yanrui Jin, Yong Geng

Bulletin of Chinese Academy of Sciences (Chinese Version)

To achieve carbon peak and carbon neutrality, as well as common prosperity, is the key decision of the Chinese government. By addressing coordinated regional development and based upon balanced and reasonable distribution of income and carbon emission rights principles, the study aims to develop an equilibrium model to achieve regional carbon transfer payment. Carbon transfer payment can help adjust regional fiscal revenues so that the income distribution system is more in line with the scientific normal distribution characteristics under the common prosperity goal. Such a measure can address both equity and efficiency, balance carbon emission rights and development rights, contribute …
