Distribution Of Dioecious Eastern Red Cedar (Juniperus Virginiana) Along An Environmental Gradient In Ogallala, Ne, Taylor Sloey
Distribution Of Dioecious Eastern Red Cedar (Juniperus Virginiana) Along An Environmental Gradient In Ogallala, Ne, Taylor Sloey
Department of Environmental Studies: Undergraduate Student Theses
Abstract
The purpose of this research was to study the sex distribution and energy allocation of dioecious Eastern Red Cedars (Juniperus virginiana) along an environmental resource gradient. The trees surveyed were growing in a canyon located at the University of Nebraska’s Cedar Point Biological Research Station in Ogallala, Nebraska. Due to the geography of this canyon, environmental factors necessary for plant growth should vary depending on the tree’s location within the canyon. These factors include water availability, sun exposure, ground slope, and soil nitrogen content, all of which are necessary for carbon acquisition.
Juniperus virginiana is a dioecious conifer. Dioecious …
The Effects Of Ornamentation On Wolf Spider Foraging, Mari Pesek
The Effects Of Ornamentation On Wolf Spider Foraging, Mari Pesek
Department of Environmental Studies: Undergraduate Student Theses
ABSTRACT: As a secondary sexual trait that can increase reproductive success, ornamentation is believed to be costly for organisms to acquire and possess. This study investigates possible costs of ornamentation on wolf spider foraging by comparing foraging abilities of two male forms that differ in ornamentation upon maturation. The two male forms, found syntopically in a mixed population in Mississippi, USA, resemble two sibling species: Schizocosa ocreata, in which males develop large black brushes on their forelegs upon maturation, and Schizocosa rovneri, in which males lack ornamentation following maturation. Individuals of both forms participated in foraging trials as penultimates (juveniles) …
Relating Bike Racks And Bike Ridership, John Sens
Relating Bike Racks And Bike Ridership, John Sens
Department of Environmental Studies: Undergraduate Student Theses
Abstract The purpose of this thesis was to investigate the relationship between bicycle ridership and bike racks in a given area. The goal was to discern whether or not the density of bike racks determines the number of riders in the area. I predicted that there would be higher ridership in the areas with a denser bike rack concentration. To investigate this point, I set up five different areas of varying sizes with a similar number of bike racks, and then observed them over a period of 5 business days. By using a simple tally of the bikes found on …
Relatin Dissolved Oxygen Concentration To Fish Distribution In Jarecki Lake, Adam Sutton
Relatin Dissolved Oxygen Concentration To Fish Distribution In Jarecki Lake, Adam Sutton
Department of Environmental Studies: Undergraduate Student Theses
Abstract Water temperature and dissolved oxygen (DO) profiles were measured once every month from mid July to mid February in a relatively deep sand-pit lake in southeast Nebraska. These profiles showed depleted DO concentrations below the thermocline during summer stratification indicating areas fish will likely avoid in summer months. Colder temperatures in fall caused complete mixing of the water column allowing fish to inhabit all depths of the lake. An inverse temperature stratification occurred directly below the ice during winter months as ice cover cooled the surface water to below 4 degrees Celsius. Ice cover also blocked air – water …
Herbicides And Amphibian Populations, Zach Shirk
Herbicides And Amphibian Populations, Zach Shirk
Department of Environmental Studies: Undergraduate Student Theses
Amphibians are a unique class of species that are found worldwide except Antarctica and Greenland. They range in size from a few millimeters to over six feet long. Amphibian’s habitats are as various as their size, but one thing in common is that amphibians require an aquatic location to breed. Amphibians live in deserts, mountain prairies, rain forest, wetlands, and almost everywhere in between. Amphibians are an integrated part of most natural ecosystems across the world. Amphibians are a critical part of many food chains; they provide the important link between secondary and tertiary consumers. Amphibians are indicator species in …

Lead Detection In Water: Using Hydroxyapatite And Atomic Absorption, Nicolas Cantarero
Lead Detection In Water: Using Hydroxyapatite And Atomic Absorption, Nicolas Cantarero
Department of Environmental Studies: Undergraduate Student Theses
Hydroxyapatite is a mineral that is very inexpensive, easily made, and binds well to lead. In this procedure its application will be paired with Flame Atomic Absorption Spectroscopy (Flame AA) to detect lead concentrations in water to ppb levels. While ppb concentrations of lead are too dilute to produce a response from the Flame AA by using Hydroxyapatite to concentrate lead molecules from a larger volume and dissolving the Hydroxyapatite into a smaller volume it may be able to produce a response. The method could provide an inexpensive, efficient, and accurate way to detect lead concentrations to the ppb level …

Changes In Producer Attitudes Towards Windbreaks In Eastern Nebraska, 1983 To 2009, Kim Tomczak
Changes In Producer Attitudes Towards Windbreaks In Eastern Nebraska, 1983 To 2009, Kim Tomczak
Department of Environmental Studies: Undergraduate Student Theses
Abstract Windbreaks are rows of trees or shrubs arranged on the landscape to reduce wind speed. In agricultural landscapes we find them as farmstead windbreaks, livestock windbreaks and field windbreaks. While farmstead and livestock windbreaks are well accepted by the agricultural community, field windbreaks are often viewed differently. A 1982 study of the attitudes of farmers in Eastern Nebraska indicated that many of the producers were around the age of 50 and that they used different types of windbreaks. This study repeated that survey in the same. When compared to data from 1982, farmers today are not educated about the …

Abstract The goal of this project is to evaluate the effectiveness of bioswells in protecting water quality from urban runoff. The hypothesis tested in this project is that water in bioswells improves water quality. Water quality in both a bioswell and an underground concrete lined ditch, both containing ground and surface water, were tested for certain water quality parameters. These parameters consisted of: Dissolved Oxygen, pH, water temperature, weather temperature, Total Dissolved Solids, Specific Conductivity, Alkalinity, Total Dissolved Carbon, Chemical Oxygen Demand, and depth and width of the sampling site. An additional contaminant that was looked at was motor oil. …
A Survey Of Western United States Instream Flow Programs And The Policies That Protect A River's Ecosystem, Kyle Jackson
A Survey Of Western United States Instream Flow Programs And The Policies That Protect A River's Ecosystem, Kyle Jackson
Department of Environmental Studies: Undergraduate Student Theses
The Western United States can best be described as a vast, varying land, with the high plains to the east and the jagged horizons of Rockies to the west. However there is one common trait shared by these states: the lack of water resources. With the continued development of this land, the fact that water is scarce is becoming more real. This issue became more difficult to handle as the public became more aware that many competing uses existed for the finite resource, and those different uses were degrading the natural environments of the surface waters. With this realization instream …
