Climate warming and related drivers of soil thermal change in the Arctic are expected to modify the distribution and dynamics of carbon contained in perennially frozen grounds. Thawing of permafrost in the Mackenzie River watershed of northwestern Canada, coupled with increases in river discharge and coastal erosion, triggers the release of terrestrial organic matter (OMt) from the largest Arctic drainage basin in North America into the Arctic Ocean. While this process is ongoing and its rate is accelerating, the fate of the newly mobilized organic matter as it transits from the watershed through the delta and into the marine system …

Towards A Global Sustainable Development Agenda Built On Social–Ecological Resilience, Murray W. Scown, Robin K. Craig, Craig R. Allen, Lance Gunderson, David G. Angeler, Jorge H. Garcia, Ahjond Garmestani

School of Natural Resources: Faculty Publications

Non-technical summary. The United Nations’ sustainable development goals (SDGs) articulate societal aspirations for people and our planet. Many scientists have criticised the SDGs and some have suggested that a better understanding of the complex interactions between society and the environment should underpin the next global development agenda. We further this discussion through the theory of social–ecological resilience, which emphasises the ability of systems to absorb, adapt, and transform in the face of change. We determine the strengths of the current SDGs, which should form a basis for the next agenda, and identify key gaps that should be filled.

Publications

Plant diseases significantly reduce crop yields, threatening food security and agricultural sustainability. Fungi are the most destructive type of phytopathogen, and they are responsible for major yield losses in some of the most crucial crops grown across the world. In this study, a fungus isolate was detected from infected tomato plants and molecularly identified as Pythium aphanidermatum (GenBank accession number MW725032). This fungus caused damping-off disease and was shown to be pathogenic. Moreover, the expression of five pathogenesis-related genes, namely PR-1, PR-2, PR-3, PR-4, and PR-5, was quantitatively evaluated under the inoculation of tomato with …

Predicting Groundwater Spring Locations From Topographic And Climatic Data Using Maxent Modeling, Ayten Ece Koc

USF Tampa Graduate Theses and Dissertations

The World Resources Institute reveals that 17 countries face extremely high levels of water stress. Moreover, with increasing population and industrialization, the gap between water supply and demand increases day by day around the world. Groundwater is a key freshwater source, and springs are important resources as they enable to access groundwater. Therefore, it is crucial to monitor, protect, and manage groundwater springs. The first step in spring management is to recognize and define freshwater resources and to determine the locations of groundwater springs that serve as natural discharge points. Traditionally, field studies have been employed to determine the locations …

Deficit Irrigation Management For Irrigated Corn In Nebraska: Economically Viable?, Lia Nogueira, Cory Walters, Emily O'Donnell, Wesley Peterson, Suat Irmak

Cornhusker Economics

In this study we determine the economic value of deficit irrigation management using both technological and methodological advancements. The use of soil moisture probes represents the technological improvement. We provide improvements in the methodology as follows. Regarding data, we employ a field-size study, instead of plots, where the irrigation decision is determined by the moisture level in the soil measured through a soil moisture probe. Regarding the understanding of the yield response to water, although we examine the commonly used quadratic function, we improve upon this specification by also examining an alternative response function, the linear response stochastic plateau. Our …

Effectiveness Of Sansevieria Plants To Purify The Vocs In Air Caused By The Use Of Febreeze And Diffuser Contaminants, Garrett Hacker, Quinn Whidden, Alayna Wagner, Zach Palmer, Brystal Beyer

Undergraduate Research Conference

Volatile organic compounds (VOCs) are a danger to every household that has access to chemical products such as air fresheners or select cleaning products. VOCs are dangerous when people are around high concentrations for any extended period. This experiment was conducted to examine the ability of sansevieria plants to filter VOCs added from normal household products. The plants used in this experiment were propagated into smaller pieces in order to fit into capsules. To begin testing, the contaminants were added to the capsules and the VOC levels were measured overtime with the Ion Science Tiger sensor. The basic trend of …

Spot-Fire Distance Increases Disproportionately For Wildfires Compared To Prescribed Fires As Grasslands Transition To Juniperus Woodlands, Victoria M. Donovan, Dillon T. Fogarty, Dirac L. Twidwell Jr

School of Natural Resources: Faculty Publications

Woody encroachment is one of the greatest threats to grasslands globally, depleting a suite of ecosystem services, including forage production and grassland biodiversity. Recent evidence also suggests that woody encroachment increases wildfire danger, particularly in the Great Plains of North America, where highly volatile Juniperus spp. convert grasslands to an alternative woodland state. Spot-fire distances are a critical component of wildfire danger, describing the distance over which embers from one fire can cause a new fire ignition, potentially far away from fire suppression personnel. We assess changes in spot-fire distances as grasslands experience Juniperus encroachment to an alternative woodland state …

Urban Studies and Planning Faculty Research Publications

Urban neighborhoods with locations of environmental contamination, known as brownfields, impact entire neighborhoods, but corrective environmental remedial action on brownfields is often tracked on an individual property basis, neglecting the larger neighborhood-level impact. This study addresses this impact by examining spatial differences between brownfields with unmitigated environmental concerns (open site) and sites that are considered fully mitigated or closed in urban neighborhoods (closed site) on the US census tract scale in Wayne County, MI. Michigan’s Department of Environment, Great Lakes, and Energy’s leaking underground storage tank (LUST) database provided brownfield information for Wayne County. Local indicators of spatial association (LISA) …

A Graphical User Interface Using Spatiotemporal Interpolation To Determine Fine Particulate Matter Values In The United States, Kelly M. Entrekin

Honors College Theses

Fine particulate matter or PM2.5 can be described as a pollution particle that has a diameter of 2.5 micrometers or smaller. These pollution particle values are measured by monitoring sites installed across the United States throughout the year. While these values are helpful, a lot of areas are not accounted for as scientists are not able to measure all of the United States. Some of these unmeasured regions could be reaching high PM2.5 values over time without being aware of it. These high values can be dangerous by causing or worsening health conditions, such as cardiovascular and lung diseases. Within …

Biodiversity is a structural indicator and has been used as a metric for conservation and management. In the hypersaline Lower Laguna Madre of Texas, a variety of organisms makes their living in and around the dominant seagrass vegetation. This study provides a general assessment of forage fishes biodiversity collected seasonally with bag seines in two sites: Holly Beach (HB) and South Bay (SB) within the most southern Texas bay system as part of a broader study on fish biology. A total of 15,880 fishes representing 32 …

Varying Genesis And Landfall Locations For North Atlantic Tropical Cyclones In A Warmer Climate, Mackenzie M. Weaver, Andra J. Garner

School of Earth & Environment Departmental Research

Tropical cyclones (TCs) are one of the most dangerous hazards that threaten U.S. coastlines. They can be particularly damaging when they occur in densely populated areas, such as the U.S. Northeast. Here, we investigate seasonal-scale variations in TC genesis and subsequent first landfall locations of > 37,000 synthetic TCs that impact the U.S. Northeast from the pre-industrial era (prior to 1800) through a very high emissions future (RCP8.5; 2080–2100). TC genesis in the Main Development Region decreases across all parts of the season from the pre-industrial to the future, with the greatest decreases in the proportion of genesis (up to 80.49%) …

Silver Carp Hypophthalmichthys Molitrix Movements In The Lower Cumberland And Lower Tennessee River, Miranda Belanger

Scholars Week

Silver Carp Hypophthalmichthys molitrix are an invasive species making up a large portion of the fish biomass in the lower portions of the Tennessee River and the Cumberland River. This species is expanding its range throughout the upper portions of these rivers, beginning with Kentucky Lake and Lake Barkley. Silver Carp rarely spawn in Kentucky Lake and Lake Barkley, but they can enter these reservoirs through the lock chamber. Thus, the bottleneck created by lock chambers can be used to control expansion of invasive Silver Carp. Although Silver Carp movement patterns have been studied in other portions of the Tennessee …

Mapping Cover Crop Usage in Calloway County, Kentucky

Ever since man made the change from hunters and gatherers to an agrarian lifestyle, erosion has slowly removed hectares of once fertile soils from crop land worldwide. As populations increase so does the demand for food, which ultimately increases the amount of erosion caused by agricultural activities. Previous farming practices once deemed revolutionary such as monocropping, synthetic fertilizers, and conventional tilling have only expedited the erosion process by destroying the soil’s microbiome. Eroded soil eventually can make its way into rivers and lakes, decreasing the water quality with abnormally high levels of …

Impacts Of Floodplain Restoration On Water Temperature And Macroinvertebrates In Whychus Creek, Oregon, Wesley Nathan Noone

Dissertations and Theses

Stream restoration is a proposed climate adaptation tool, however, outcomes of floodplain restoration on stream temperature have been debated. Despite a growing number of studies that investigated water temperature in restored streams, few have quantified thermal heterogeneity in new habitat types created by restored hydrogeomorphic processes and the impact of thermal diversity on the aquatic macroinvertebrate community. In this study, I evaluated three hypotheses: 1) restoration increases habitat diversity, 2) habitat diversity increases water temperature heterogeneity, and 3) restored reaches have more diverse macroinvertebrate communities. I collected a total of 40 macroinvertebrate samples and characterized environmental conditions in three reaches …

Role Of Age And Sex In The Effects Of Repeated Methamphetamine Exposure On Hedonic Tone In Sprague Dawley Rats, Cameron Lewis, Conor Strumberger, Joshua M. Gulley

PRECS student projects

Anhedonia is defined as a reduced or complete loss of pleasure from a previously pleasurable stimulus, and it is comprised of two dimensions:

• Hedonic anhedonia consists of a distinct loss of pleasure in consumption of a normally pleasurable stimulus.
• Motivational anhedonia involves the goal directed behavior to obtain a reward.

Withdrawal induced anhedonia following use of methamphetamine (METH) is thought to contribute to relapse behaviors^1,2 . The anhedonic effects of drug withdrawal largely depend on dose, frequency, and the duration of drug exposure^4,5,6.

The role of sex and age of exposure in this context has yet to …

Performance Of The Mineral Recovery Enhanced Desalination Pilot Water Treatment Plant, Samantha Valentine

Water Resources Professional Project Reports

There is a growing interest in treating brackish groundwater to supplement freshwater resources for inland communities in arid climates. Water recovery by desalination of brackish groundwater is challenging due to mineral scaling from ions which form carbonate and sulfate minerals, dissolved silica which forms silicates, iron, manganese, and other constituents along with the difficulties and cost of disposing of large volumes of brine from the desalination process. The MRED process consists of a pretreatment process to increase water recovery and decrease waste production from brackish groundwater. The MRED process uses a unique sequence of unit processes consisting of: (1) Air …
