Using Pimephales Promelas>/Em> As An Indicator Species For The Presence Of Endocrine Disruptors In Nebraskan Streams, Megan Rosno

Department of Environmental Studies: Undergraduate Student Theses

Specific sites in Southeast and Southwest Nebraska were chosen to add to the collective knowledge on how cattle feed lot effluents continue to have significant effects downstream of their point source locations. Both locations were sampled via seining net in first: 40.241249 latitude, -95.616191 longitude (near Barada, Nebraska), and second: 41.117368 latitude, -100.794332 longitude (directly South of North Platte in the South Platte River). They were chosen not only for their proximity to differing livestock practices of pasture vs. feed lot, but also where locals fish for the best bait fish including but not limited to fathead minnows (Pimephales …

Drought Perceptions And Management Techniques For Outdoor Recreation In The Great Plains, Lauren Uhlig

Department of Environmental Studies: Undergraduate Student Theses

Outdoor recreation generates nearly $887 billion dollars in annual consumer spending and improves quality of life by promoting physical activity (Oftedal & Schneider, 2013; Outdoor Industry Association, 2017b). This industry relies heavily on the environment and these societal benefits are at risk as climate fluctuates. Drought is a regular component of the Great Plains climate (Miao et al., 2007) and can alter the landscape, changing the demand for outdoor recreation and creating challenges for managing recreation opportunities (USDA, 2017). This thesis explores the influence of drought on individual’s willingness to participate in outdoor recreation, the variation in that influence across …

Critical Wedges And Penetrative Strain: How Does Penetrative Strain Alter The Concept Of A Critical Wedge?, Nicole L. Smith

Department of Environmental Studies: Undergraduate Student Theses

By definition, a critical wedge shows limited internal deformation, and, also by definition, penetrative strain is deformation occurring on a microscale within a deforming rock sequence. Critical wedge theory is typically used to understand the development of fold thrust belts, where variables such as the internal and basal friction, surface taper and dip of the décollement are taken into account. Numerical modeling shows that the minimum stable surface taper is dependent on the basal friction and the overburden, but that there are a range of possible tapers for a stable wedge. This study presents a series of analog models, where …

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 …

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 …

Age Structures And Growth Patterns Of Aplodinotus Grunniens In The Red River Of The North, Manitoba, Canada, Kaitlyn Elder

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 …

This happened by the extreme climate event over land lower precipitation over a period of months to years. This could affect agricultural systems around the world, within food, ecologically atmosphere condition and also the habitation food security. From the developing in the modern technology, since the environment of nature is the basic element of living creature, human would be facing the challenging of agriculture, forestry, fisheries and food …

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, 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 …

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 …

Lighting And Economic Considerations For A Hydroponic S-Based Greenhouse At Tri Cycle Farms, Laura Gray

Biological and Agricultural Engineering Undergraduate Honors Theses

Hydroponics is an agricultural technology that involves growing plants without soil, instead using other growth media with added nutrients, typically inside a controlled facility such as a greenhouse. Hydroponics-based agriculture has a number of benefits, namely that it is more water efficient, requires less intensive labor, yields higher quality crops consistently in shorter time, and is easier to control. It also has the potential to be economically advantageous, due to its ability to grow certain crops in the off-season. In Fayetteville, Arkansas, a non-profit urban farm known as Tri Cycle Farms has been seeking a way to design, build, and …

The Role Of Dendrology In Analyzing Past Climatic And Historical, Anna Sonnenfeld

Department of Environmental Studies: Undergraduate Student Theses

The study of dendroclimatology uses tree growth responses to climate variables to reconstruct regional, national, and global chronologies from tree-rings (Speer, 2010). The species of focus was Q. macrocarpa (bur oak) located in Spring Creek Prairie because of its potential to hold a chronological history of environmental limitations and management practices in the area. The objective of this research is to: 1) determine the impact of available soil moisture on the annual growth of Q. macrocarpa in Wachiska Woods, 2) determine the effect of management practices on Q. macrocarpa annual growth in Wachiska Woods. Eight Q. macrocarpa specimens were identified; …

Hydroponics: Effect Of Ph On Different Cucumber Varieties, Mikaela Krumrei

Department of Environmental Studies: Undergraduate Student Theses

Plants are generally grown using soil as the main medium to supply the essentials necessary for growth, but as population grows and land decreases it is important to expand the knowledge of other growth mediums such as hydroponics. The purpose of this study is to provide information on hydroponic growing systems, specifically how the pH of the water effects cucumber plant growth and if different varieties of cucumber plants may have varying reactions to the pH. The hypothesis was that the plants would grow efficiently at pH of 5.0 and worst at pH of 7.5. This experiment was conducted in …

The Effect Of Land Development In Small Communities On A People's Sense Of Place, Alivia Michalski

Department of Environmental Studies: Undergraduate Student Theses

Sense of place is an extensively researched concept that refers to the relationship (cultural, economic, societal, spiritual, and physical) between a person and their surroundings. Often a person’s sense of place, or connection to the land, can lead them to develop strong place attachment, or a human-place bond, with certain physical locations. Studies done on place attachment show that people with strong connections to natural areas where they live are more willing to demonstrate environmentally responsible behavior. This kind of behavior is important in the upcoming years, as communities begin to expand, develop more land, and use more resources. In …
