Introduction: Social-Ecological Resilience And Law, Ahjond S. Garmestani, Craig R. Allen, Craig Anthony Arnold, Lance H. Gunderson
Craig Anthony (Tony) Arnold
Environmental law is intimately connected to ecological concepts and understanding. The legal instruments, institutions, and administration of law in the United States are predicated on assumptions that nature is globally stable and that the inherent variability in ecological systems is bounded. This current legal framework is based upon an understanding of ecological systems operating near an equilibrium, or if disturbed, moving back toward an equilibrium. Such assumptions make much current environmental law ill-suited for many pressing environmental issues (Ruhl 1999; Garmestani et al. 2009; Craig 2010; Verchick 2010; Benson and Garmestani 2011). Emerging environmental challenges, such as cross-boundary water governance ...

Several frameworks have been developed to assess the resilience of social-ecological systems, but most require substantial data inputs, time, and technical expertise. Stakeholders and practitioners often lack the resources for such intensive efforts. Furthermore, most end with problem framing and fail to explicitly address trade-offs and uncertainty. To remedy this gap, we developed a rapid survey assessment that compares the relative resilience of social-ecological systems with respect to a number of resilience properties. This approach generates large amounts of information relative to stakeholder inputs. We targeted four stakeholder categories: government (policy, regulation, management), end users (farmers, ranchers, landowners, industry), agency ...

There is a fundamental difference between the ways in which ecologists and lawyers view uncertainty: in the study of ecology, uncertainty provides a catalyst for exploration, whereas uncertainty is antithetical to the rule of law. This issue is particularly troubling in environmental management, where the tensions between law and ecology become apparent. Rather than acknowledge uncertainties in management actions, legal frameworks often force a false sense of certainty in linking cause and effect. While adaptive management has been developed to deal with uncertainty, laws and legal wrangling can be obstacles to implementation. In this article, we recommend resilience-based governance – “adaptive ...
An Underground Radio Wave Propagation Prediction Model For Digital Agriculture, 2019 Purdue University
An Underground Radio Wave Propagation Prediction Model For Digital Agriculture, Abdul Salam
Underground sensing and propagation of Signals in the Soil (SitS) medium is an electromagnetic issue. The path loss prediction with higher accuracy is an open research subject in digital agriculture monitoring applications for sensing and communications. The statistical data are predominantly derived from site-specific empirical measurements, which is considered an impediment to universal application. Nevertheless, in the existing literature, statistical approaches have been applied to the SitS channel modeling, where impulse response analysis and the Friis open space transmission formula are employed as the channel modeling tool in different soil types under varying soil moisture conditions at diverse communication distances ...
The Social And Ecological Significance Of Hervey Bay Queensland For Eastern Australian Humpback Whales (Megaptera Novaeangliae), 2019 Southern Cross University
The Social And Ecological Significance Of Hervey Bay Queensland For Eastern Australian Humpback Whales (Megaptera Novaeangliae), Trish Franklin
Dr Trish Franklin
This study provides the first detailed long-term research on the seasonal pod characteristics, seasonal social behaviour and temporal segregation of different reproductive and maturational classes of humpback whales in Hervey Bay (Queensland, Australia). The overall aim was to investigate the importance of the Bay for particular classes of humpback whales. This study revealed that Hervey Bay is an important habitat for mature females accompanying immature whales early in the season and mothers with calves later in the season. Hervey Bay is neither a terminal destination nor a calving or breeding area but rather a stopover early in the southern migration.
Using X-Ray Fluorescence To Analyze Fire Impacted Soil And Vegetation Composition, 2019 Kansas State University Libraries
Using X-Ray Fluorescence To Analyze Fire Impacted Soil And Vegetation Composition, Dylan Darter
Kansas State University Undergraduate Research Conference
In our lab, I am using an X-ray fluorescence (XRF) to measure the concentrations of metals in sediments from subalpine lakes. Our goal is to measure the biogeochemical consequences of wildfires over the last 2000 years. This study looks at the elemental composition of different lake cores, and vegetation samples from areas of the “Big Burn” fire of 1910. This fire burned across several states in the Rocky Mountain region. With our XRF data we are able to see how the fire impacted the soils and how long after the fire proper soil composition can occur. This study can be ...
Hour-Level Resolution On Consumption Pattern Of Substance Abuse, 2019 Murray State University
Hour-Level Resolution On Consumption Pattern Of Substance Abuse, Jarrett Mauk, Rhiannon Huffines, Brittney Nelson, Tara Croft, Bikram Subedi
Conventional survey-based approaches of determining the consumption statistics of drugs in communities are suffered from non-response biases, and typically underestimate the actual consumption. Time and cost-intensive conventional approaches, therefore, can’t be utilized to determine high-resolution temporal variability in drug consumption. In this study, the temporal trend of consumption of 10 illicit and 26 prescribed neuropsychiatric drugs was determined at hour-level resolution utilizing wastewater-based epidemiology. The hourly composite raw wastewater (every 10 minutes) samples were collected for three consecutive days in a typical week (total of 72 samples), analyzed for target drug residues using UPLC-MS/MS, and back-calculated the consumption ...
Delineation Of Ohio River Flood Zones In Ballard County Using Remote Sensing, 2019 Murray State University
Delineation Of Ohio River Flood Zones In Ballard County Using Remote Sensing, Nathan Rister
The purpose of this study was to use remote sensing to map flood zones in Ballard County as it correlates to the Ohio River flood gauges. This will help Wildlife managers to know which areas are most likely to be flooded by simply looking at river gauges and prevent them to having to check which areas are flooded in person. By using this technique wildlife managers will be able to save time and resources as well as better manage wildlife areas along the Ohio River.
Monitoring Lesser Known Harmful Algal Blooms On The Oregon Coast, 2019 Portland State University
Monitoring Lesser Known Harmful Algal Blooms On The Oregon Coast, Taylor Dodrill, Tawnya D. Peterson, Matthew Hunter, Micah Rogers
OHSU-PSU School of Public Health Annual Conference
Ocean warming has expanded the niche of harmful algal blooms (HABs), including HABs previously believed to pose little risk of shellfish contamination in the Pacific Northwest. Monitoring efforts in Washington and California have demonstrated that Dinophysis spp. is a HAB of emerging concern and has been linked to diarrhetic shellfish poisoning events. However, quantitative monitoring for Dinophysis spp. on the Oregon Coast has been limited. This analysis provides a preliminary characterization of risk that Dinophysis spp. poses to shellfish consumers in Oregon. Furthermore, we assess the predator-prey interaction between Dinophysis spp. and its prey, Mesodinium rubrum, to determine whether their ...
Determination Of Conversion Factors For Various Calibration Geometries Using Barium-133 In A Silver Zeolite Cartridge, 2019 Louisiana State University
Determination Of Conversion Factors For Various Calibration Geometries Using Barium-133 In A Silver Zeolite Cartridge, Amin Hamideh
LSU Master's Theses
Iodine-131 (I-131) is a major fission product among other radionuclides released during a nuclear incident. This radioiodine has a half-life of 8.02 days and the primary organ of uptake through ingestion or inhalation is the thyroid gland. For these reasons, nuclear power plants must routinely monitor I-131 through air sampling. Currently, there are two adsorbing media to collect I-131: activated charcoal and silver zeolite cartridges. Silver zeolite cartridges are generally used during a post nuclear incident due to its affinity for iodine while not adsorbing noble gases such as krypton-85 and xenon-135. After an air sample is taken from ...
Measurement Of Solar Spectral Irradiance And Surface Ozone At Carrollton, Georgia, Usa, During The Great American Eclipse On 21 August 2017, Kirthi Tennakone, L Ajith Desilva, Charles A. Zander*, Shea Rose, Austin B. Kerlin
Georgia Journal of Science
Measurements conducted at the University of West Georgia, Carrollton, Georgia, during the time of the solar eclipse of 21st August 2017 demonstrated that the integrated spectral irradiance in defined wavelength ranges in the ultraviolet and visible calculated as a fraction of the total irradiance reached a minimum at maximum obscuration of the Sun, whereas in an infrared range it was maximum. The method of analysis adopted supports the view that the changes in spectral irradiance during highly obscured partial phases is a consequence of limb darkening. In a surface ozone measurement, a minimum in ozone concentration occurred 30 +_ ...

Dramatic growth in herbicide-resistant (HR) weeds in the United States threatens farm profitability and may undercut environmentally beneficial farming practices. When HR weeds move across farm boundaries due to ecological processes or human action, a common pool resource challenge emerges, requiring farmer cooperation to manage such weeds effectively. We investigate the scope for cooperative management using responses to a national survey on HR weed issues to test a recursive model of three preconditions for collective action: (1) concern about HR weeds migrating from nearby lands; (2) communication with neighbors about HR weeds; and (3) belief that cooperation is necessary for ...
A Theoretical Model Of Underground Dipole Antennas For Communications In Internet Of Underground Things, Abdul Salam, Mehmet C. Vuran, Xin Dong, Christos Argyropoulos, Suat Irmak
The realization of Internet of Underground Things (IOUT) relies on the establishment of reliable communication links, where the antenna becomes a major design component due to the significant impacts of soil. In this paper, a theoretical model is developed to capture the impacts of change of soil moisture on the return loss, resonant frequency, and bandwidth of a buried dipole antenna. Experiments are conducted in silty clay loam, sandy, and silt loam soil, to characterize the effects of soil, in an indoor testbed and field testbeds. It is shown that at subsurface burial depths (0.1-0.4m), change in soil ...

Water Quality In Southern Accomack County Watersheds, 2019 Virginia Institute of Marine Science
Water Quality In Southern Accomack County Watersheds, Richard A. Snyder, Paige G. Ross
Expansion of poultry grow out houses in Accomack County, VA has raised concerns for water quality impacts both seaside and bayside where harvesting marine resources and aquaculture operations may be affected. The dust and litter from the poultry houses are potential sources of nitrogen, phosphorous, and fecal contamination to watersheds and receiving waters. Siting regulations, storm water controls, and management of litter storage and handling are designed to limit these impacts, yet no analysis has been implemented to verify the efficacy of these protective measures. This investigation sampled watersheds after a 2 week dry period prior to a storm event ...
Stomatal Conductance Measurement For Toxicity Assessment In Zero-Effluent Constructed Wetlands: Effects Of Landfill Leachate On Hydrophytes, 2019 Wroclaw University of Environmental and Life Sciences
Stomatal Conductance Measurement For Toxicity Assessment In Zero-Effluent Constructed Wetlands: Effects Of Landfill Leachate On Hydrophytes, Andrzej Białowiec, Jacek A. Koziel, Piotr Manczarski
Agricultural and Biosystems Engineering Publications
In this research, we explore for the first time the use of leaf stomatal conductance (gs) for phytotoxicity assessment. Plants respond to stress by regulating transpiration. Transpiration can be correlated with stomatal conductance when the water vapor pressure gradient for transpiration is constant. Thus, our working hypothesis was that the gs measurement could be a useful indicator of the effect of toxic compounds on plants. This lab-scale study aimed to test the measurement of gs as a phytotoxicity indicator. Our model plants were two common hydrophytes used in zero-effluent constructed wetlands for treating landfill leachate. The toxic influence of two ...
