Analyzing The Effects Of Of Seasonal Land Cover And Precipitation On The Sediment Delivery Ratio Of An Agriculture Dominated Watershed., Jonah Liebman
Electronic Theses and Dissertations
Soil erosion is of escalating importance as increasing population and climate change have put increasing pressures on agricultural food production. Vegetation and precipitation are two factors that control the amount of soil erosion extant within a region. Sediment delivery ratios (SDRs) assess the ratio of soil eroded from a watershed system that is permanently removed from the system through stream sediment discharge. Using 1) river discharge and sediment concentration data and 2) the Revised Universal Soil Loss Equation (RUSLE), this thesis analyzes fluctuations in monthly SDRs for an average hydroclimatological crop-harvest season for the Senachwine Creek watershed, IL. Through calculating …

Building Adaptive Capacity In Tribal Communities Of The Missouri River Basin To Manage Drought And Climate Extremes: A Case Study From The Wind River Indian Reservation, Crystal J. Stiles, Natalie Umphlett, Mitch Cottenoir
HPRCC Personnel Publications
Native American peoples of the Northern and Central Plains have long endured harsh climate conditions, such as floods and droughts, and they possess valuable traditional knowledges that have enhanced their resilience to these extreme events. However, in recent times, limited capacity to adapt to a rapidly changing climate combined with a lack of resources have increased tribes’ vulnerability to climate extremes and their associated impacts. In response, a number of projects have been developed to assist tribes with their self-identified climate- and drought-related needs, particularly in the context of on-reservation decision-making. In this case study, we present an engagement strategy …

Effects Of Light, Nutrients, And Salts On Microbial Biofilm Productivity And Detrital Processing In Aquatic Mesocosms, Bethanie Brooke Howard-Parker
Graduate Theses and Dissertations
Anthropogenic activities associated with urbanization, agriculture, and resource extraction continue to increase to support increasing needs of the growing population. These activities increase the amounts of pollutants entering freshwater streams and put aquatic ecosystems at structural and functional risk. Aquatic microbes play an important role in detrital processing in streams as a key linkage in moving carbon from detrital stocks into aquatic food webs. My research investigates the effects of light, nutrients, and salts on detrital microbes and decomposition in freshwaters using a mesocosm approach. In chapter one, I modified a current priming effect (PE) hypothesis model to include light …
The Impact Of Extreme Heat On Environmental Justice Communities In California: Assessing Equity In Climate Action Plans, 2020 University of San Francisco
The Impact Of Extreme Heat On Environmental Justice Communities In California: Assessing Equity In Climate Action Plans, Karishma S. Becha
Master's Projects and Capstones
Climate change projections suggest extreme heat events will be more frequent over the next few decades. Extreme heat has both negative environmental and social impacts as it affects energy security, public health by increasing the risk of heat-related illnesses and stresses food and crop supply through prolonged droughts. The impacts of extreme heat will also disproportionately affect communities of low economic status. Because of this, there is a need for better climate action plans that can adapt to and mitigate the impacts brought upon by extreme heat that does not disproportionately impact vulnerable communities. This research analyzed local government Climate …

What’S Going To Happen To My Pancakes? The Impacts Of Climate Change Upon Blueberries And Sugar Maple, Ashley Kayser
Honors College
The United Nations believes that the foremost challenge of the future will be climate change. Because of human use of fossil fuels, greenhouse gases have been released into the atmosphere at unsustainable rates, which have resulted in an altered climate that will impact weather patterns around the globe. There have already been measurable shifts in precipitation and temperature in many regions; in the state of Maine the general trend has been toward higher temperatures and increased precipitation. This is resulting in impacts to agriculture throughout the state. Blueberries and sugar maple are two culturally and economically valuable crops which will …

Climate change is the paramount challenge of today for a sustainable future. Mitigation of greenhouse gas (GHG) emissions is necessary to reduce the associated risks and impacts on society. Using the EPA’s SIT and literature review, comprehensive GHG-emissions inventories were developed for the state of Nebraska over 25 years (1990-2015) and agricultural GHG emissions inventories were developed for the Midwest U.S for one year (2016). Nebraska’s net emissions increased from 56.2 million metric tons of carbon dioxide equivalent (MMtCO2e) in 1990 to 87.4 MMtCO2e in 2016. Agriculture was found to be the sector with the most …
Effects Of Bridge Sites On Freshwater Mussel Community Structure And Density, 2020 Otterbein University
Effects Of Bridge Sites On Freshwater Mussel Community Structure And Density, Holly Rundle
Undergraduate Honors Thesis Projects
Freshwater Mussels (family Unionidae) are one of the most imperiled group of species found in the United States. Construction activities, such as bridges, can affect sedimentation rates and local deposition, as well as the hydrologic flow of the stream. Since mussels are protected in Ohio, surveys must be done prior to bridge construction to determine the impact of the project on mussel resources. Our study used data from survey reports conducted in Ohio from 2013-2019 at bridge sites. We organized the data to determine mussel community structure and density directly underneath bridges compared to away from bridges. We found the …

Comparative Physiology Of Honey Bees (Apis Mellifera L.) Exposed To Chlorantraniliprole, 2020 University of Nebraska - Lincoln
Comparative Physiology Of Honey Bees (Apis Mellifera L.) Exposed To Chlorantraniliprole, Jennifer Williams
Department of Entomology: Dissertations, Theses, and Student Research
One outstanding threat to the honey bee, Apis mellifera L., is the unintended exposure of these pollinators to agricultural pesticides. Anthranilic diamides, such as chlorantraniliprole, work in target pests through activation of the ryanodine receptor causing rapid feeding cessation, lethargy, paralysis, and eventual death. Chlorantraniliprole exhibits low acute toxicity to honey bees but relatively little information exists regarding effects of chlorantraniliprole exposure beyond mortality. The acute toxicity and metabolic detoxification enzyme activities following oral exposure were determined in the honey bee and the model crop pest, the fall armyworm (Spodoptera frugiperda, J.E. Smith). Additionally, chlorantraniliprole effects on honey bee …

Assessment Of The Environmental And Economic Impacts Of Fossil Fuel Subsidies, 2020 University of Lynchburg
Assessment Of The Environmental And Economic Impacts Of Fossil Fuel Subsidies, Evan Cobey
Undergraduate Theses and Capstone Projects
Renewable sources of energy remove dependence on fossil fuels. When renewable sources are adopted, they reduce damage to the environment from burning fossil fuels. Currently, fossil fuels are cheaper to produce, causing renewable energy to be used less. In the United States, fossil fuels receive heavy subsidies, keeping renewable energy in the periphery. This research explores the environmental and economic effects of subsidizing fossil fuels. Findings include that governments and citizens lose money when fossil fuels are subsidized. While subsidization initially makes them cheaper, they create expenses that are not factored into original costs, such as damage to human health …

Most state and provincial fish and wildlife agencies have access to important information about patterns in sportsperson participation through their license databases. Using transaction data from Nebraska Game and Parks Commission’s electronic hunting and fishing license system, we tracked license purchases of Nebraska, USA, resident license holders in 2010 through 2017. We categorized sportspersons by gender and yearly purchases as hunting only (Hunter), fishing only (Angler), a combination of hunting and fishing (Hunter–Angler), or no purchases (Inactive). The probability of movement among active sportsperson groups was limited and varied little based on initial group participation. The Angler group had the …

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications
Recreational angler surveys typically collect information on how anglers access a fishery. Yet, it is unclear how this information is useful for fisheries management and conservation. The objective of this study was to compare behavior (e.g., party size, time fished, and numbers of fish released and harvested) of bank and boat anglers, representing two angler-access types. Bank and boat anglers were surveyed across 29 Nebraska waterbodies from April through October, 2007–2017. We documented behavioral differences between bank and boat anglers that varied as a function of waterbody size and season. Patterns of party size, time fished, and numbers of fish …
