Persistent Organic Pollutants And Mortality In The United States, Kristiann Fry, Melinda Power
Persistent Organic Pollutants And Mortality In The United States, Kristiann Fry, Melinda Power
GW Research Days 2016 - 2020
Background/Objectives: Persistent organic pollutants (POPs) are environmentally and biologically persistent chemicals that include polybrominated diphenyl ethers (PBDEs), per- and polyfluoroalkyl Substances (PFASs), polychlorinated biphenyls (PCBs), and organochlorine (OC) pesticides. Currently, there is limited data on the association between exposure to POPs and the risk of mortality in the general US population. The objective of this study was to determine if higher exposure to POPs are associated with greater risk of all-cause, cancer, heart/cerebrovascular disease, or other-cause mortality in persons aged 60 years and older.
Methods: The analyses included participants aged 60 years and older from the 1999-2006 National Health and …

The Coastal Monitor
There is something enchanting and vibrant about viewing the coast. Every day at CERCOM we are welcomed by either a vivid sunrise, a view of the barrier island Fire Island and a blending of the sky across the horizon, ultimately flooding the Great South Bay with either clouds or sunshine that reveals the Bay’s surface as either shimmering with sunlight, or an integration of sky and water as an endless ocean. I don’t normally wax poetic but the varying sights along the near shore ocean and this embayment beckon our scientific inquisitiveness. What’s below the surface water? How do animals …

A Web Based Real Time Nitrogen Leaching Calculator, Saeideh Samani, Babak Samani, Haishun Yang
Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research
While nitrogen (N) is an essential nutrient for corn, its leaching to ground water is an serious environmental issue and a hazard to public health. N leaching is closely linked to weather factors, especially rainfall. Prediction of N leaching in cropping systems is critical to improvement of crop management and reduction of N leaching. The objective of this project is to develop a web app that predicts in real-time mode N leaching across Nebraska using real-time weather data.
We are in the processing of developing the web app and expect a prototype to be running in 2017 cropping season. Field …

Advancing Collaborative Solutions: Lessons From The Oregon Sage-Grouse Conservation Partnership (Sagecon), Jennifer H. Allen, Turner Odell, Julia Babcock, Charis Henrie
National Policy Consensus Center Publications
The Sage-Grouse Conservation Partnership, also known as “SageCon,” was an unprecedented collaborative effort among federal, state, and private stakeholders to address landscape-scale threats to greater sage-grouse while also acknowledging rural economic and community interests across eastern Oregon’s sagebrush range. A U.S. Fish and Wildlife Service (USFWS) preliminary finding that the sage-grouse warranted listing under the endangered species act, and a subsequent court settlement setting a deadline for a final listing decision were key drivers for SageCon participants to seek proactive solutions to protect the bird. A cadre of diverse Eastern Oregon stakeholders with experience working collaboratively on related public lands …
Mapping Of Environmental Effects Of Hydraulic Fracking Using Satellite Imagery, Donald Correll
Mapping Of Environmental Effects Of Hydraulic Fracking Using Satellite Imagery, Donald Correll
Scholars Week
Hydrofracking is a drilling technique that has been around since the late 1940s. Since the 1990s, a widespread technique has been developed known as horizontal drilling. The process starts by drilling a well vertically or at an angle into the ground about 1-2 miles. The well is then encased with steel or cement, to “ensure” nothing leaks into the groundwater. Once the layer of rock has been reached, drillers begin drilling horizontally up to around one mile. Fracking fluid is pumped into the well at very high pressures (up to 9,000 psi), which creates fissures/cracks in the rock. Oil and/or …

DEEPEND Datasets
Shelf and slope waters in the Deep Water Horizon oil spill (DWHOS) area are known to serve as critical spawning, nursery, and foraging habitat of several important oceanic species including billfishes (e.g. blue marlin, white marlin, sailfish), tunas (bluefin tuna, yellowfin tuna), and other pelagic taxa (swordfish, dolphinfishes). The aim of this component was to further investigate potential ecological effects of the DWHOS on pelagic fishes during the early life period. Larval fishes were sampled from 48 stations in the northern Gulf of Mexico and cruise data was collected at each site including latitude/longitude, date, time and environmental data (sea …

Geographic Variation Of Cirques On Iceland: Factors Influencing Cirque Morphology, Heather A. Ipsen, Rachael E. Grube, Jessica F. Lee, Sarah M. Principato
Environmental Studies Faculty Publications
Cirques are one of the most common glacial landforms in alpine settings. They also provide important paleoclimate information (e.g. Meierding 1984; Evans 2006). The purpose of this study is to fill in gaps in the climate record of Iceland by conducting a quantitative analysis of cirques in three regions in Iceland: Tröllaskagi, the East Fjords, and Vestfirðir. Iceland, located in the center of the North Atlantic Ocean, contains many small glaciers, in addition to large ice caps. The glaciers on Iceland are particularly sensitive to variations in oceanic and atmospheric circulation (Andresen et al. 2005; Geirsdóttir et al., 2009; Ólafsdóttir …

National Drought Mitigation Center: Faculty Publications
Probabilistic forecasts of U.S. Drought Monitor (USDM) intensification over 2-, 4-, and 8-week time periods are developed based on recent anomalies in precipitation, evapotranspiration, and soil moisture. These statistical forecasts are computed using logistic regression with cross validation. While recent precipitation, evapotranspiration, and soil moisture do provide skillful forecasts, it is found that additional information on the current state of the USDM adds significant skill to the forecasts. The USDM state information takes the form of a metric that quantifies the ‘‘distance’’ from the next-higher drought category using a nondiscrete estimate of the current USDM state. This adds skill because …

Homestead National Monument Of America, Bat Acoustic Monitoring, September 2016, Daniel S. Licht
United States National Park Service: Publications
Abstract
Homestead National Monument of America is a 211-acre park located in an agrarian landscape in southeastern Nebraska. From September 16 to October 1, 2016, park staff deployed acoustic monitors at three sites in the park for purposes of monitoring night-time bat activity. The three sites averaged 179, 48, and 33 bat detections per night. Night-time bat activity was generally highest in the 1-2 hours following sunset.
Based on the acoustic surveys the big brown (Eptesicus fuscus), eastern red (Lasiurus borealis), northern long-eared (Myotis septentrionalis) and evening bats (Nycticeius humeralis) were present at the …

Nutrient Contamination From Non-Point Sources: Dissolved Phosphate In Surface And Subsurface Waters At Eku Meadowbrook Farm, Madison County, Kentucky, Hunter R. Evans, Reid E. Buskirk, Walter S. Borowski, Jonathan M. Malzone
EKU Faculty and Staff Scholarship
Farms are non-point sources for nutrient contaminants that drain into watersheds and contribute to eutrophication and other environmental problems. Eastern Kentucky University’s Meadowbrook Farm raises both crops and livestock, causing dissolved phosphorus in the form of orthophosphate (PO43-) from fertilizer and animal manure to enter surface and subsurface waters, eventually flowing into Muddy Creek, a tributary of the Kentucky River.
We sampled surface water, springs, and water from French drains that emanate from the farm, and also sampled Muddy Creek waters from May through August 2016. Typically, 1 to 2 days after sampling, we colorimetrically measured dissolved …

Nutrient Contamination From Non-Point Sources: Dissolved Nitrate And Ammonium In Surface And Subsurface Waters At Eku Meadowbrook Farm, Madison County, Kentucky, Reid E. Buskirk, Hunter R. Evans, Walter S. Borowski, Jonathan M. Malzone
EKU Faculty and Staff Scholarship
Agricultural activities often contaminate watersheds with excess nutrients leading to poor water quality and eutrophication. We assayed dissolved nutrient levels in surface and subsurface waters of Eastern Kentucky University’s Meadowbrook Farm in order to assess levels of dissolved nutrients leaving its farmland and draining into the Muddy Creek watershed. The Farm raises both crops and livestock so that nutrient sources include fertilizer and manure. We sampled springs, runoff, and subsurface pipe drainage as well as Muddy Creek on six days from May to August 2016 under a variety of weather conditions. Using established, standard colorimetric methods, we measured nitrate (NO …

DEEPEND Datasets
This data set includes the biological PAH (Polycyclic Aromatic Hydrocarbons) data of target species collected during the DP01 (May 1-8, 2015) and DP02 cruises (August 8-21, 2015) in the Northern Gulf of Mexico. The target fish species include Ceratoscopelus warmingii, Chaulidus spp., Diaphus spp., Argyropelecus spp, Lampanyctus alatus, and Sigma elongatum. Also, analysis of shrimp (Acanthephyra purpurea) and cephalopod (Grimalditeuthis bonplandi, Histioteuthis corona, Japetella diaphana) samples were conducted. PAHs were analyzed following modified EPA method 8270D and QA/QC strict protocols. Detection and quantification of PAHs were performed using a gas chromatograph/mass spectrometric detector (GC/MS/MS).
Environmentally Friendly Industries: An Examination Of Ecotourism As The Solution To The Environmental Degradation Caused By The International Tourism Industry, Whitney Michael
Honors Theses – Charlotte Campus
The increasing visibility of ecological alterations due to global climate change have required high-impact industries to reexamine their environmental impact. Transnational organizations such as the United Nations have identified the current management practices of the international tourism industry as a significant contributing factor to global warming. The high volume implications of the large-scale establishments necessary to lodging facilities in the tourism trade are responsible for damages such as resource depletion and pollution. Existing levels of environmental impact show irreparable and imminent damage to the world environment if current methods of the industry are allowed to continue.

Increased Habitat Connectivity Homogenizes Freshwater Communities: Historical And Landscape Perspectives, Angela L. Strecker, Jeffrey Thomas Brittain
Increased Habitat Connectivity Homogenizes Freshwater Communities: Historical And Landscape Perspectives, Angela L. Strecker, Jeffrey Thomas Brittain
Environmental Science and Management Faculty Publications and Presentations
-
Increases in habitat connectivity can have consequences for taxonomic, functional, and genetic diversity of communities. Previously isolated aquatic habitats were connected with canals and pipelines in the largest water development project in the US history, the Columbia Basin Project (CBP; eastern Washington, USA), which also altered environmental conditions; however, the ecological consequences are largely unknown.
-
Using a historical dataset, we examined long-term patterns in zooplankton communities, water chemistry and clarity, testing the hypothesis that increased connectivity will result in taxonomic homogenization. Further, we tested contemporary drivers of communities using a comprehensive set of environmental and landscape variables.

Developing A Representative Snow-Monitoring Network In A Forested Mountain Watershed, Kelly E. Gleason, Anne Nolin, Travis R. Roth
Environmental Science and Management Faculty Publications and Presentations
A challenge in establishing new ground-based stations for monitoring snowpack accumulation and ablation is to locate the sites in areas that represent the key processes affecting snow accumulation and ablation. This is especially challenging in forested montane watersheds where the combined effects of terrain, climate, and land cover affect seasonal snowpack. We present a coupled modeling approach used to objectively identify representative snow-monitoring locations in a forested watershed in the western Oregon Cascades mountain range. We used a binary regression tree (BRT) non-parametric statistical model to classify peak snow water equivalent (SWE) based on physiographic landscape characteristics in an average …

Environmental Science and Management Faculty Publications and Presentations
Land use legacies can have a discernible influence in present-day watersheds and should be accounted for when designing conservation strategies for riverine aquatic life. We describe the environmental history of three watersheds within the Grande Ronde subbasin of the Columbia River using General Land Office survey field notes from the 19th century. In the two watersheds severely impacted by Euro-American land use, stream channel widths—a metric representing habitat simplification—increased from an average historical width of 16.8 m to an average present width of 20.8 m in large streams; 4.3 m to 5.5 m in small, confined or partly confined streams; …

United States Department of Energy: Publications
The release of carbon dioxide (CO2) and other greenhouse gases (GHGs) due to human activity is increasing global average surface air temperatures, disrupting weather patterns, and acidifying the ocean. Left unchecked, the continued growth of GHG emissions could cause global average temperatures to increase by another 4°C or more by 2100 and by 1.5 to 2 times as much in many midcontinent and far northern locations. Although our understanding of the impacts of climate change is increasingly and disturbingly clear, there is still debate about the proper course for U.S. policy—a debate that is very much on display …

Coral Bleaching And The Effect Of Disturbances On The Damselfish Community On Lizard Island, Australia, Alejandra Munoz
Coral Bleaching And The Effect Of Disturbances On The Damselfish Community On Lizard Island, Australia, Alejandra Munoz
Independent Study Project (ISP) Collection
Coral reefs are characterized by their dynamic ecological processes that supports a high diversity through the recruitment of marine species and temporal disturbances that can have positive effects on the system. In the face of global climate change however, coral reefs face intense coral bleaching and increased degradation as they may begin to have less time to recover between bleaching events in the near future. Little is known on the long term effects of coral bleaching and habitat degradation on reef fish communities and much less is known about the mechanisms that bring about changes to reef fish assemblages.

Can Community Structure Track Sea-Level Rise? Stress And Competitive Controls In Tidal Wetlands, Lisa M. Schile, John Callaway, K M. Suding, N M. Kelly
Environmental Science
Climate change impacts, such as accelerated sea-level rise, will affect stress gradients, yet impacts on competition/stress tolerance trade-offs and shifts in distributions are unclear. Ecosystems with strong stress gradients, such as estuaries, allow for space-for-time substitutions of stress factors and can give insight into future climate-related shifts in both resource and nonresource stresses. We tested the stress gradient hypothesis and examined the effect of increased inundation stress and biotic interactions on growth and survival of two congeneric wetland sedges, Schoenoplectus acutus and Schoenoplectus americanus. We simulated sea-level rise across existing marsh elevations and those not currently found to reflect …
Malta : Natural Freshwater Resources, Lisamarie Pereira
Malta : Natural Freshwater Resources, Lisamarie Pereira
Global Public Health
The aim of this paper is to discuss Malta’s struggle with limited natural freshwater resources. Malta currently uses aquifers to obtain natural freshwater. For over a decade, aquifers have been under pressure from over-abstraction. Due to this issue, Malta has not been able to obtain enough natural freshwater for agriculture and basic living. The biggest risk due to over-abstraction is retrieving a smaller volume of freshwater. In Malta’s attempted interventions, the biggest issue is the Maltese government’s misconceptions. The Maltese government believes the country has unlimited natural freshwater resources. Due to this misconception, nothing is being done to actively fix …

Environmental Science
Due to increasing pressures on water resources, there is a need to monitor regional water resource availability in a spatially and temporally explicit manner. However, for many parts of the world, there is insufficient data to quantify stream flow or ground water infiltration rates. We present the results of a pixel-based water balance formulation to partition rainfall into evapotranspiration, surface water runoff and potential ground water infiltration. The method leverages remote sensing derived estimates of precipitation, evapotranspiration, soil moisture, Leaf Area Index, and a single F coefficient to distinguish between runoff and storage changes. The study produced significant correlations between …

A Spanner In The Works: Human–Elephant Conflict Complicates The Food–Water–Energy Nexus In Drylands Of Africa, Bruce Schulte, Mwangi Githiru, Urbanus Mutwiwa, Simon Kasaine
Biology Faculty Publications
The two major conservation issues for drylands of Africa are habitat loss or degradation and habitat fragmentation, largely fromagriculture, charcoal production, and infrastructural development. A key question for management is how these landscapes can retain their critical ecological functions and services, while simultaneously supporting resilient livelihoods. It is a clear nexus question involving food (agriculture), water, and energy (fuelwood), which is complicated by human–wildlife conflicts. While these could appear disparate issues, they are closely connected in dryland forest landscapes of Africa where elephants occur close to areas of human habitation. For instance, crop failure, whether due to weather or wildlife …
