Changes In Plant Phenology In The Central United States In Response To Climate Change, 2019 University of Nebraska - Lincoln
Changes In Plant Phenology In The Central United States In Response To Climate Change, Sarah Fagras
Department of Environmental Studies: Undergraduate Student Theses
Plant phenophases are highly sensitive to changes in temperature, precipitation, and photoperiod and have recently been identified as an indicator of climate change. Flowering time in particular appears to be sensitive to changes in temperature and plants around the world have already been observed flowering earlier than previously recorded. To determine how plants in the Midwest and Great Plains have reacted to climate change from the 1880s to present, 1,926 plant specimens made up of 10 species were examined to determine their phenophase and date of collection for each specimen was recorded. Analysis of these specimens shows that flowering time …

Department of Environmental Studies: Undergraduate Student Theses
A fishery and its components are an integral part of society and contribute not only economically, but also socially and physically to the health and well-being of many countries. There are approximately 12.5 million people who are employed in fishery-related careers, and according to the Wildlife and Sport Fish Restoration, there were over 33.1 million people who fished recreationally. To successfully manage a fish population, one must have a well-rounded knowledge about the species and the environment it inhabits. There is very little previous research done on the growth of Aplodinotus grunniens, otherwise known as freshwater drum (FWD), making it …

Nitrate Contamination And Nitrogen Isotope Compositions In The Bazile Groundwater Management Area - A Water Quality Study. Creighton, Ne, 2019 University of Nebraska - Lincoln
Nitrate Contamination And Nitrogen Isotope Compositions In The Bazile Groundwater Management Area - A Water Quality Study. Creighton, Ne, Sydney Corcoran
Department of Environmental Studies: Undergraduate Student Theses
Surface water nitrogen contamination is a pervasive issue in Nebraska, and agricultural practices are the main source of nitrogen input to streams (Spalding and Exner, 1993). Nitrate can come from inorganic fertilizers such as anhydrous ammonia, or animal waste. Studies have been conducted on nitrates dating back to 1947 (Addleman, 1985). The Bazile Groundwater Management Area (BGMA) located in northeast Nebraska has historically had high nitrate contamination. This qualitative study assesses the seasonal sources of nitrogen to stream water. It is predicted that the source of input is from commercial synthetic fertilizers. By using nitrogen- oxygen isotope methods, the source …

Biogeography Of Endemic Dragonflies Of The Ozark-Ouachita Interior Highlands, 2019 University of Arkansas, Fayetteville
Biogeography Of Endemic Dragonflies Of The Ozark-Ouachita Interior Highlands, Wade Alexander Boys
Graduate Theses and Dissertations
A common pattern across many taxonomic groups is that relatively few species are widespread while the majority are restricted in their geographic ranges. Such species distributions are used to inform conservation status, which poses unique challenges for rare or cryptic species. Further, priority status is often designated within geopolitical boundaries, which may include only a portion of a species range. This, coupled with lack of distributional data, has resulted in species being designated as apparently rare throughout some portions of their range, which may not accurately reflect their overall conservation need. The Interior Highlands region of the central United States …
Amphibian And Reptile Community Responses To Forest And Riparian Disturbance, 2019 University of Arkansas, Fayetteville
Amphibian And Reptile Community Responses To Forest And Riparian Disturbance, Jacquelyn Christine Guzy
Graduate Theses and Dissertations
Riparian zones are transitional, semi-terrestrial areas regularly influenced by freshwater. These areas serve as dispersal corridors for many animal and plant species and ultimately function as important reservoirs of biodiversity in altered landscapes. While much of the riparian habitat in the United States has been affected by anthropogenic activities, management actions may mitigate potentially negative influences of these activities. For example, Streamside Management Zones (i.e., riparian buffers; SMZs) are commonly implemented within managed forests to protect water quality, but may also provide habitat for riparian-associated wildlife. Yet, little research has rigorously addressed the value of SMZs for wildlife, particularly cryptic …

Nitrate Accumulation In The Vadose Zone Of Waverly's Wellhead Protection Area, 2019 University of Nebraska - Lincoln
Nitrate Accumulation In The Vadose Zone Of Waverly's Wellhead Protection Area, Cleome Mullison
Department of Environmental Studies: Undergraduate Student Theses
Agriculturally intensive areas such as Nebraska are faced with a growing threat: groundwater nitrate pollution caused by years of applying nitrogen based fertilizer. Nitrate pollution can be attributed to several factors such as manure from cattle ranching and wastewater plants, but Nebraska’s main threat is derived from years of leached nitrogen fertilizer. When nitrogen fertilizer is applied it has one of several fates: plant uptake, volatilization, leaching or run-off. When nitrates leach beyond the plant root system, they are unable to be absorbed by the plant and ultimately move slowly towards the regional ground water table. While nitrate accumulation in …

Examining The Effects Of Uv On Latex And Nitrile Glove Degradation, Dana Christine Handke
Department of Environmental Studies: Undergraduate Student Theses
Medical gloves, both nitrile and latex, are used as a protective barrier to limit the spread of disease. Gloves are a single use product and their demand is set to increase by 9 to10 percent each year. In 2008, it was estimated that 100 billion gloves were used globally each year (Scott, 2008). This study is exploratory in nature, to determine if Ultra Violet light (UV) exposure can cause an acceleration in the breakdown of latex and nitrile gloves. It was hypothesized that the tensile strength and length to breakage for both glove types, latex and nitrile, would decrease after …

Student Perception Of Industrial Agriculture: Effects On Migrant Workers And The Environment, 2019 University of Nebraska - Lincoln
Student Perception Of Industrial Agriculture: Effects On Migrant Workers And The Environment, Brigitta Bogue, Emma Sorensen
Department of Environmental Studies: Undergraduate Student Theses
Companies such as Tyson Foods and Costco are creating problems through their use of industrial farming practices in Nebraska, such as concentrated animal feeding operations (CAFOs) and monocropping, to generate profit at the cost of humans and the environment. Those most affected are migrant farmworkers from Mexico. The environment is threatened because CAFOs generate greenhouse gases, and pollute nearby waterways with nitrogen. This paper addresses the following research questions: Are students’ perceptions of industrial agricultural companies, such as Costco and Tyson, positive or negative? Are students aware of these issues? How do these perceptions affect issues of sustainability and environmental …

Activity Patterns Of Nebraskan Wildlife On A Prairie Landscape, 2019 University of Nebraska - Lincoln
Activity Patterns Of Nebraskan Wildlife On A Prairie Landscape, Dillon Hanson
Department of Environmental Studies: Undergraduate Student Theses
Avoiding a particular species temporally can be an effective way to live amongst predator and competing species when spatial avoidance is not available. If a predator and prey species overlap temporally there is potential for high predation of the prey species by the predator, while if two predators overlap temporally there is high potential for competition and a loss of opportunities and resources for each species. I assessed if native mammalian species on a natural prairie landscape showed signs of avoidance through their activity patterns. I used photographic sampling to quantify the temporal activity patterns of species at Spring Creek …
