Evaluation Of Electrophoretic Protein Extraction And Database-Driven Protein Identification From Marine Sediments, Eli K. Moore, Brook L. Nunn, Jessica F. Faux, David R. Goodlett, H. Rodger Harvey

OES Faculty Publications

Intact proteins comprise a major component of organic carbon and nitrogen produced globally and are likely an important fraction of organic matter in sediments and soils. Extracting the protein component from sediments and soils for mass spectral characterization and identification represents a substantial challenge given the range of products and functionalities present in the complex matrix. Multiple forms of gel electrophoresis were evaluated as a means of enhancing recovery of sedimentary protein before proteomic characterization and compared with a direct enzymatic digestion of proteins in sediments. Resulting tryptic peptides were analyzed using shotgun proteomics and tandem mass spectra were evaluated …

Long-Term Changes To The Frost-Free Season As A Function Of Climatic Continentality, Ian Blaylock

Mahurin Honors College Capstone Experience/Thesis Projects

The beginning, end, and length of the annual frost-free season vary considerably both spatially and temporally. The continentality of the climate of a given area has a close connection with the magnitude and nature of these variations. Long term changes in the frost-free season can be divided into three distinct phases: a lengthening of the frost-free season in the early 20^th century, a shortening in the mid-20^th century, and a renewed, intensified lengthening from 1970 to today. While oceanic and ultraoceanic climates experience decreased incidence of frosts relative to their continental counterparts, analysis has shown that overall 20 …

Nutrient Dynamics In Stormwater Runoff From Green Roofs With Varying Substrate, John Michael Fohner

Graduate Theses and Dissertations

One major concern with urban development is the increasing amount of stormwater runoff from large expanses of impervious surfaces. These impervious surfaces reduce the ability of stormwater to infiltrate into the soil and eventually groundwater, which leads to greater amounts of surface runoff. Green technology serves as a viable solution to many of the environmental problems presented by modern development. Fifteen mock, extensive green roofs were built in the fall of 2008 at the Watershed Research and Education Center in Fayetteville, Arkansas. The goals of this project were to (1) measure the amount of stormwater runoff from varying treatments and …

The Effects Of Property Rights On Ocean Resources: Two Possible Solutions To The Tragedy Of The Commons, Nathan David Miller

Honors Program Theses

Property rights affect how people use resources. Enforcement regimes are able to set clear laws with well-defined property rights. Governments set laws for conservation and economic success. Ocean resources suffer from overuse. Industry and the environment both benefit from regulations that promote ocean conservation. This paper will analyze how the current state of ocean property rights leads to the depletion of ocean resources. Though there are many possible solutions to overfishing, I will analyze two potential solutions to overexploitation in the commercial fishing industry: marine protected areas (MP As) and individual transferable quotas (ITQs ). A synthesis of previous research …

Modeling Passive Solar Distillation In Las Vegas, Nv, Noe I. Santos

College of Engineering: Graduate Celebration Programs

Project Background

• Many rural areas on the planet do not have easy access to clean water!

• Water distillation basins are capable of distilling water by using incident solar radiation to evaporate polluted water.

• Current thermodynamic models used to predict behavior require instantaneous data; requires the use of expensive equipment.

• Distillation basins are dependent on multiple meteorological variables: insolation, temperature, wind speed, cloud cover.

• Non‐linear behavior is difficult to predict for long term operations.

Impact Of Sludge Treatment Processes On Estrogen Concentration In Wastewater Sludge, Erica Marti

College of Engineering: Graduate Celebration Programs

Endocrine-disrupting compounds (EDCs), such as estrogen, are known to be present in the aquatic environment at concentrations that affect fish and other wildlife. For example, juvenile male fish exposed to estrogen will synthesize vitellogenin, which is a female-specific protein. Estrogen exposure is also linked to sex reversal, intersexuality, and inhibition of gonadal growth (Jobling et al., 1996).

Wastewater treatment plants are major contributors of EDCs into the environment. EDCs end up in wastewater as a result of natural excretion from the body or being washed off the skin. WWTPs are not designed to remove these substances. As a result, EDCs …

Nantucket Shellfish Management Plan, Kristin Uiterwyk, Steve Bliven, Dan Leavitt, Jack Wiggin, Urban Harbors Institute, University Of Massachusetts Boston

Office of Community Partnerships Posters

Nantucket’s shellfish resources are an important part of the Island’s history, culture, and economy. Nantucket waters support one of the country’s last wild-caught bay scallop fisheries. Elsewhere along the Atlantic coast, fishing pressure, habitat loss, and disease have severely depleted bay scallop populations. Although Nantucketers continue to make a living harvesting shellfish from the Island’s waters, many do so with concern for the future of the resources and the habitats that support them. Urban Harbors Institute (UHI) provided technical assistance to the community to develop a Shellfish Management Plan (SMP) that addresses issues of water quality, habitat loss, climate change, …

Water And Energy Balance Response Of A Riparian Wetland To The Removal Of Phragmites Australis, Phillip Mykleby

Department of Earth and Atmospheric Sciences: Dissertations, Theses, and Student Research

Vegetation and climate both play integral roles in water availability, particularly for arid to semi-arid regions. Changes in these variables can lead to extreme shortages in water for regions that rely on water for crop irrigation (i.e., the Great Plains). The objective of this study is to evaluate the impacts of vegetation on water availability in the Republican River basin in central Nebraska. Decreases in streamflow have been observed in the river basin for many years and, as a result, an invasive riparian plant species (Phragmites australis) is being removed in an effort to reduce evapotranspiration and reclaim …

Feeding Habitats Of The Gulf Sturgeon, Acipenser Oxyrinchus Desotoi, In The Suwannee And Yellow Rivers, Florida, As Identified By Multiple Stable Isotope Analyses, Kenneth J. Sulak, J. J. Berg, M. Randall

United States Geological Survey: Staff Publications

Stable ¹³C, ¹⁵N, and ³⁴S isotopes were analyzed to define the feeding habitats of Acipenser oxyrinchus desotoi in the Suwannee and Yellow River populations. For the majority (93.9%) of Suwannee sub adults and adults, 13C and 34S signatures indicate use of nearshore marine waters as primary winter feeding habitat, probably due to the limiting size of the Suwannee Sound estuary. In the Yellow River population, 13C isotope signatures indicate that adults remain primarily within Pensacola Bay estuary to feed in winter, rather than immigrating to the open Gulf of Mexico. A minor Suwannee River subset (6% of …

The Impacts Of Population Density, And State & National Litter Prevention Programs On Marine Debris, Melissa Rose Brogle

USF Tampa Graduate Theses and Dissertations

Marine debris is improperly disposed of solid waste, also called litter, which is deposited in the marine environment (NOAA, 2010). Litter prevention techniques such as fines, cleanups, incentives, and others, can help to decrease litter, and ultimately decrease marine debris. This research analyzed 2000 and 2010 International Coastal Cleanup (ICC) data obtained from The Ocean Conservancy to ascertain whether certain litter prevention techniques did reduce amounts and types of marine debris found in coastal areas. The litter prevention techniques analyzed included state bottle bills, voluntary monofilament fishing line recycling programs, and the Keep America Beautiful (KAB) cigarette butt litter prevention …

Invasionsoft: A Web-Enabled Tool For Invasive Species Colonization Predictions, Matthew W. Johnston, Samuel J. Purkis

Marine & Environmental Sciences Faculty Articles

Predicting and averting the spread of invasive species is a core focus of resource managers in all ecosystems. Patterns of invasion are difficult to forecast, compounded by a lack of user-friendly species distribution model (SDM) tools to help managers focus control efforts. This paper presents a web-based cellular automata hybrid modeling tool developed to study the invasion pattern of lionfish (Pterois volitans/miles) in the western Atlantic and is a natural extension our previous lionfish study. Our goal is to make publically available this hybrid SDM tool and demonstrate both a test case (P. volitans/miles) and a …

Heterogeneous Detection Probabilities For Imperiled Missouri River Fishes: Implications For Large-River Monitoring Programs, Joshua T. Schloesser, Craig P. Paukert, Wyatt J. Doyle, Tracy D. Hill, Kirk D. Steffensen, Vince H. Travnichek

United States Geological Survey: Staff Publications

Occupancy modeling was used to determine (1) if detection probabilities (p) for 7 regionally imperiled Missouri River fishes (Scaphirhynchus albus, Scaphirhynchus platorynchus, Cycleptus elongatus, Sander canadensis, Macrhybopsis aestivalis, Macrhybopsis gelida, and Macrhybopsis meeki) differed among gear types (i.e. stationary gill nets, drifted trammel nets, and otter trawls), and (2) how detection probabilities were affected by habitat (i.e. pool, bar, and open water), longitudinal position (five 189 to 367 rkm long segments), sampling year (2003 to 2006), and season (July 1 to October 30 and October 31 to June 30). Adult, large-bodied fishes were …

Habitat And Prey Availability Attributes Associated With Juvenile And Early Adult Pallid Sturgeon Occurrence In The Missouri River, Usa, Bryan D. Spindler, Steven R. Chipps, Robert A. Klumb, Brian D. S. Graeb, Michael C. Wimberly

United States Geological Survey: Staff Publications

The pallid sturgeon Scaphirhynchus albus is a federally endangered species native to the Missouri and lower Mississippi Rivers, USA. As part of recovery efforts, over 360 000 pallid sturgeon have been stocked into the Missouri River since 1994, and a standardized, long-term monitoring program was initiated in 2003. Understanding the distribution and habitat requirements of juvenile and early adult pallid sturgeon (fork length <720 mm, age <10 yr) is an important goal of the monitoring and recovery programs. In this study, we collected information on habitat characteristics and prey availability from the upper Missouri River along the Nebraska-South Dakota border and compared these attributes between capture (present) and non-capture (absent) locations (N = 59). To evaluate the relative influence of habitat and prey availability on pallid sturgeon occurrence, we examined several candidate models using an informationtheoretic approach. A prey availability model had the most support and included site-specific information on Diptera and Ephemeroptera abundance. A habitat-based model showed that juveniles and early adults were found in relatively deeper water and avoided areas where bottom velocities were greater than 1.2 m s−1. Although not as well supported as the prey-effects model (evidence ratio = 6.4), habitat features also provided a plausible model for predicting occurrence. The models developed here could be used to evaluate pallid sturgeon habitat potential in the Missouri River basin and help guide future monitoring and conservation management of this endangered species.

Agriculture Futures: Potential Rural Land Uses On The Palusplain, Rodney Safstrom, Nicolyn Short Dr

Resource management technical reports

The purpose of this project was to identify agricultural land use options and opportunities within the Serpentine–Jarrahdale and Murray Shires, with particular focus on the Palusplain wetland section. The report will contribute to the Department of Planning’s natural resource management plan for the region and guide development of regional and local planning strategies. Historically, the Palusplain was a slowly moving, interconnected, seasonal wetland system with areas of higher ground. Extensive clearing and drainage occurred in the late 1800s through to the mid-1900s to facilitate agriculture; however, agriculture has been found to be a major contributor of nutrients to the system. …

The U.S. Environmental Protection Agency (USEPA) has been encouraging states to accerlate their efforts in developing numeric nutrient criteria to promulgate within respective water quality standards and regulations. Based on USEPA recommendations, many states are pursuing nutrient criteria development by assessing frequency distributions and stressor‐response relationships in historical databases, various special studies and the literature. The mini‐workshops described here were targeted toward state agency personnel and stakeholder groups with an interest in understanding statistical techniques that could be used to aide, guide and support numeric nutrient criteria. An initial workshop was conducted at the USEPA Regional Technical Assistance Group meeting …

Sestonic Chlorophyll-A And Nutrient Relationships Across The Red River Basin, Usa, Brian E. Haggard, J. Thad Scott, Scott D. Longing, John T. Metrailer

Arkansas Water Resources Center Technical Reports

The Red River is a trans‐boundary, multi‐jurisdictional basin, where water‐quality standards often change at the state lines. The state agencies with USEPA Region VI focused resources to organize water‐quality data from within this basin and have it statistically analyzed to evaluate the relationships between nutrients and sestonic chlorophyll‐a (chl‐a). There were 152 sites within the Red River Basin that had nutrient and sestonic chl‐a data, and these sites were narrowed down to 132 when a minimum number of observations was required. Sestonic chl‐a levels increased with increasing nutrient concentrations; these significant regressions were used to predict nutrient concentrations at 10 …

Water quality trends were analyzed using flow‐adjusted constituent concentrations of phosphorus, nitrogen, sediment, sulfate and chloride, and parametric and non‐parametric statistical techniques …

Strategies For Wildlife Disease Surveillance, Jonathan M. Sleeman, Christopher J. Brand, Scott D. Wright

United States Geological Survey: Staff Publications

Epidemiologic surveillance is defined by the Centers for Disease Control and Prevention (CDC) as the "ongoing systematic and continuous collection, analysis, and interpretation of health data': The objective of surveillance is to generate data for rapid response to the detection of a disease of concern to apply prevention, control, or eradication measures as well as to evaluate such interventions. This is distinct from disease monitoring, which usually does not involve a particular response to disease detection.

Surveillance for wildlife diseases has increased in importance due to the emergence and re-emergence of wildlife diseases that are threats to human, animal, and …

National Drought Mitigation Center: Faculty Publications

Alaska encompasses several climate types because of its vast size, high-latitude location, proximity to oceans, and complex topography. There is a great need to understand how climate varies regionally for climatic research and forecasting applications. Although climate-type zones have been established for Alaska on the basis of seasonal climatological mean behavior, there has been little attempt to construct climate divisions that identify regions with consistently homogeneous climatic variability. In this study, cluster analysis was applied to monthly-average temperature data from 1977 to 2010 at a robust set of weather stations to develop climate divisions for the state. Mean-adjusted Advanced Very …

Drought Monitoring: Historical And Current Perspectives, Michael J. Hayes, Mark D. Svoboda, Brian D. Wardlow, Martha C. Anderson, Felix Kogan

National Drought Mitigation Center: Faculty Publications

Drought is a normal, recurring feature of climate throughout the world, with characteristics and impacts that can vary from region to region. Figure 1.1 illustrates the regular occurrence of drought within the United States between 1895 and 2010 with approximately 14% of the country, on average (plotted by black dotted line), experiencing severe to extreme drought conditions during any given year. Drought conditions can persist in a region for several years, as occurred in the United States in the 1930s, 1950s, and early 2000s, and tree ring and other proxy records confirm that multiple-year droughts are part of the long-term …

Future Opportunities And Challenges In Remote Sensing Of Drought, Brian D. Wardlow, Martha C. Anderson, Justin Sheffield, Bradley D. Doorn, James P. Verdin, Xiwu Zhan, Matthew Rodell

National Drought Mitigation Center: Faculty Publications

The value of satellite remote sensing for drought monitoring was first realized more than two decades ago with the application of Normalized Difference Vegetation Index (NDVI) data from the Advanced Very High Resolution Radiometer (AVHRR) for assessing the effect of drought on vegetation, as summarized by Anyamba and Tucker (2012, Chapter 2). Other indices such as the Vegetation Health Index (VHI) (Kogan, 1995) were also developed during this time period and applied to AVHRR NDVI and brightness temperature data for routine global monitoring of drought conditions. These early efforts demonstrated the unique perspective that global imagers like AVHRR could provide …

Microwave Remote Sensing Of Soil Moisture Science And Applications, Son V. Nghiem, Brian D. Wardlow, David Allured, Mark Svoboda, Doug Lecomte, Matthew Rosencrans, Steven K. Chan, Gregory Neumann

National Drought Mitigation Center: Faculty Publications

Soil moisture is a fundamental link between global water and carbon cycles and has major applications in predicting natural hazards such as droughts and floods (National Research Council, 2007). From precipitation data, soil wetness can be estimated by hydrological land-surface models. In the United States, preliminary precipitation data are based on measurements gathered from many active stations nationwide each month, and it takes 3–4 months to assemble final, quality-controlled data. In the western United States, some climate divisions may have no stations reporting in a particular month or may lack first- or second-order stations, and significant blockages by mountains limit …
