Visualization Of Productivity Zones Based On Nitrogen Mass Balance Model In Narragansett Bay, Rhode Island, Jongsun Kim, Myung Hwangbo, Patricia S. Thibodeau, Georgia Rhodes, Emma Hogarth, Stewart Copeland

School of Earth, Environmental, and Marine Sciences Faculty Publications and Presentations

Primary productivity in the coastal regions, linked to eutrophication and hypoxia, provides a critical understanding of ecosystem function. Although primary productivity largely depends on riverine nutrient inputs, estimation of the extent of riverine nutrient influences in the coastal regions is challenging. A nitrogen mass balance model is a practical tool to evaluate coastal ocean productivity to understand biological mechanisms beyond data observations. This study visualizes the biological production zones in Narragansett Bay, Rhode Island, USA, where hypoxia frequently occurs, by applying a nitrogen mass balance model. The Bay is divided into three zones - brown, green, and blue zones - …

A Thermodynamics-Based Versatile Evapotranspiration Estimation Method Of Minimum Data Requirement For Water Resources Investigations, Jozsef Szilagyi, Richard D. Crago

School of Natural Resources: Faculty Publications

A recent, two-parameter version of the thermodynamically derived complementary relationship (CR) of evaporation has been tested on a monthly basis at 124 FLUXNET stations around the globe. Local, station-by-station calibration explained 91% (R2) of the variance in eddy-covariance (EC) obtained latent-heat fluxes with the same Nash-Sutcliffe efficiency (NSE) value. When the dimensionless Priestley-Taylor parameter (α) was expressed as a universal function (f) of the estimated wet-environment air temperature (Tw), station-by-station calibration of the single dimensionless parameter, b (accounting for moisture advection), yielded an R² value of 87% and NSE of 86%. Global calibration (all stations …

Impact Of Forest Management On Ozark Big-Eared Bat (Corynorhinus Townsendii Ingens) Prey And Foraging Ecology, Gemma L. Marsh

ATU Theses and Dissertations 2021 - Present

Ozark big-eared bats (Corynorhinus townsendii ingens) are an endangered species of bat found only in Oklahoma and Arkansas. I conducted a study on the impact of forest management treatments, such as prescribed fire and mechanical thinning, in White Rock Mountain Wildlife Management Area, which is home to a maternity colony of Ozark big-eared bats. My goal was to understand how prescribed fire and mechanical thinning influence Ozark big-eared bat prey and foraging, and therefore be able to provide management recommendations for the habitat of this endangered species. My results indicated that bat prey availability was influenced by forest structure, …

Holocene Rice Rats (Genus Oryzomys) From The Upper Mississippi River Drainage Basin, Hugh H. Genoways

Zea E-Books Collection

The expansion and collapse of the geographic range of the Texas rice rat (Oryzomys texensis) in the upper Mississippi River drainage basin at the end of the Holocene was a unique event in North American mammals. In a period of about 4000 years with a point of origin near the American Bottom in Illinois, these small rodents extended their geographic range in a straight-line distance of over 950 km to the west into Nebraska and the same distance to the east into Pennsylvania. Then in less than 400 years this range expansion collapsed back to a point where …

Nebraska Water Center: Faculty Publications

The amount of antibiotics and personal care products entering local sewage systems and ultimately natural waters is increasing and raising concerns about long-term human health effects. We developed an adsorptive photocatalyst, Cu_0.5Mn_0.5Fe₂O₄ nanoparticles, utilizing co-precipitation and calcination with melamine, and quantified its efficacy in removing paraben and oxytetracycline (OTC). During melamine calcination, Cu_0.5Mn_0.5Fe₂O₄ recrystallized, improving material crystallinity and purity for the adsorptive–photocatalytic reaction. Kinetic experiments showed that all four parabens and OTC were removed within 120 and 45 min. We found that contaminant adsorption and reaction …

The Characterization Of Riparian Vegetation In Agriculture Drains Impacted By Phragmites Australis And Drain Management: A Southwestern Ontario, Canada Case Study, Ryan Mackenzie Graham

Electronic Theses and Dissertations

Agricultural drainage systems are important components of regional ecosystems and play key roles in ecosystem functioning. Biodiversity is a service provided by drains which is not fully understood in agriculturally dominated areas and is disrupted consistently by drain management, specifically in drains invaded by Phragmites australis. The objective of this thesis was to characterize the contribution of regional vegetational biodiversity provided by drainage systems, across sites representing a gradient of management frequencies. Drains were separated into management categories: Low (managed +5 years ago), Medium (managed every 3-5 years), or High (managed yearly). Plant abundance was measured and biodiversity indices (Species …

Dynamic Fallowing In The Middle Rio Grande: A Look At The Environmental Water Leasing Program, Jared Wood

Water Resources Professional Project Reports

The Environmental Water Leasing Program (EWLP) is a federally-funded collaborative effort of the Middle Rio Grande Conservancy District and the U.S. Bureau of Reclamation that has paid irrigators in the Middle Rio Grande to temporarily lease water rights and forgo their water use so that it may be used to provide environmental flows for the endangered Rio Grande Silvery Minnow. The program operates in a sometimes socially contentious context, in a region with an overallocated, legally constrained water system, to offer much needed water management flexibility. While dynamic fallowing payments for ecosystem services programs like the EWLP are common policy …

Irrigation And Innovation: Understanding Barriers To Innovative Actions To Manage Drought On Middle Rio Grande Farms, Eleanor C. Hasenbeck

Water Resources Professional Project Reports

The Rio Grande has irrigated agricultural land in central New Mexico since time immemorial. Today, agriculture in New Mexico’s Middle Rio Grande valley is adapting to an increasingly scarce water supply due to long-term drought and climate change (Dunbar et al., 2022). As supply is decreasing, demands are increasing because of several factors: an increase in evapotranspiration (Dunbar et al., 2022); population growth in the Middle Rio Grande valley (NM LFC, 2021); and legal obligations to provide water for endangered species and to Texas and Mexico (NM ISC, 2017). Agriculture is largest water use by sector in the Rio Grande …

Water resources management is becoming increasingly complex in the Middle Rio Grande Valley, where the negative impacts of climate change and growing demand for a fully allocated river put further strain on diminishing water supply. The precarity of future water availability emphasizes the importance of fully accounting for existing water rights allocations and understanding how ever changing social and ecological processes might hinder those rights from being fully realized. This study aimed at improving knowledge of the groundwater budget at Bosque del Apache National Wildlife Refuge, New Mexico by utilizing experimental methods of Darcy Flow analysis to estimate groundwater flow …

Motivations And Barriers To Participation In Community Outreach And Engagement Among Environmental And Water Resources Students And Postdocs, Sydney Donohue

Water Resources Professional Project Reports

There is a need to utilize knowledge exchange avenues between academia and non-academic communities in order to advance environmental science and engineering education. Many universities and research centers attempt to enhance knowledge sharing by organizing broader impact outreach events such as lab tours, demonstrations, hands-on activities, and public presentations. Anecdotally, at two NSF-funded centers, the Transformation Network and Center for Water and the Environment, we have seen that only the same small subset of students and postdocs frequently participate while over 70% of those invited never volunteer. This study aims to survey environmentally-focused undergraduate students, graduate students, and postdocs’ motivations …

Variability In Consumption And End Uses Of Water For Residential Users, Camilo J. Bastidas Pacheco, Jeffery S. Horsburg, Attallah A. Nour

Research Briefs

Research Objective/Summary: In most large urban water systems in the US, the residential sector consumes the majority of total supplied fresh water. In a world plagued with increasing water scarcity and climate change stresses, understanding individual home water end-uses is vital to water management and conservation. We studied the end uses of water in residential homes, both indoor and outdoor to find patterns and variations in consumption over time. Results indicate a need for more efficient water fixtures, particularly toilets, and provide an opportunity to promote conservation behavior.

Cadmium And Salinity Stressor Antagonism On Vallisneria Neotropicalis, Christopher P. Mikolaitis

<strong> Theses and Dissertations </strong>

Submerged macrophytes form the foundation of freshwater ecosystems. These organisms are sessile and are very susceptible to shifts in their environment. Heavy metals are of particular concern as they can be sequestered indefinitely in sediments and are readily taken up by rooted vegetation. In the presence of saltwater intrusions, these metals can interact with salt ions potentially changing their availability to submerged vegetation. In this study a freshwater macrophyte, Vallisneria neotropicalis, was used as a test species for interactive effects between Cd, a non-essential heavy metal, and salt stress. The metrics used to establish the individual as well as …

Meet Me In The Middle: A Scoping Review On Understanding Adolescent Needs In Climate Communication, Gwendolyn Monica Hoff Anderson

Master's Projects and Capstones

The greatest effects of climate change are likely to be felt by youth. Young people are disproportionately affected by climate change due to their critical developmental stage and lack of power, and they experience both higher severity and prevalence of mental health issues related to climate change. Strong emotions have long been recognized as potential catalysts for action, or they may lead to paralyzing feelings of being overwhelmed. Climate communication is a critical tool to spark climate concern and encourage action. Activism, in turn, may help youth manage their anxiety about climate change. This scoping review examines emerging evidence on …
