Seeing Red In A Sea Of Green: Anthocyanin Production In A Carnivorous Plant, Pinguicula Planifolia, Jenna Annis

Masters Theses

The Southeastern United States is a biological hot-spot for carnivorous plants, with over half of the North American species occurring along the Gulf Coast. Pinguicula planifolia Chapman is one of six carnivorous perennial butterwort species found in the Florida Panhandle. Among these species, only P. planifolia expresses a distinct variation of red coloration on its leaves. The functional role of foliar anthocyanins may include stress response to drought and nutrient deficiency, herbivory defense, free radical scavenging, and photoprotection. Carnivorous plant leaves face strong selection pressures to optimize prey capture and nutrient absorption. Given the frequency of these red pigments in …

Successional Changes In Leaf Nutrient Concentrations Of Woody And Herbaceous Species, Daniel Walter Kuchta

Masters Theses

Leaf nutrient concentrations are an example of a functional trait, a trait that can be used to understand community dynamics by observing how plants interact with their environment. I explored how leaf nutrient concentrations were affected over successional time by environmental changes. The majority of prior research on functional traits focuses on either woody or herbaceous species, but not both life forms simultaneously. To address this, I also explored the successional changes to leaf nutrient concentrations, separating the plant community into woody and herbaceous species.

Healthy, mature leaves were taken from 122 taxa of woody and herbaceous species in a …

Low-Head Dams On Habitat, Fish Functional Guilds And Genetic Structuring In A Midwestern River System, Shannon Cassandra Frary Smith

Masters Theses

The natural flow regime of the majority of rivers in the United States has been altered by anthropogenic structures. This loss of connectivity plays a strong role in shaping river ecosystems by altering physical habitat characteristics and shaping fish community assemblages. Although the impacts of large dams on river systems are well documented and often easy to observe, there are fewer studies on the effects of smaller low-head dams. Additionally, the influences of low-head dams on the genetic structuring of small-bodied riverine fishes have yet to be fully explored. I assessed the effects of two low-head dams on the Vermilion …

Examining The Effect Of Caffeine And Technology On Adolescent Sleep, Kaci D. Clark

Masters Theses

The current study expands upon existing sleep research by assessing adolescent caffeine consumption and technology use around bedtime and group differences in caffeine consumption and technology use in regard to sleep onset time, duration and quality, as well as symptoms of delayed sleep phase syndrome (DSPS). Participants, ranging in age from 13 to 18 years, were recruited from two Midwestern high schools and one junior high school. Online survey software was used to capture adolescents' self-reported caffeine consumption, technology use, and sleep. Adolescents who drank more caffeine did not spend significantly more time using technology at night, nor did they …

Demographics And Parasites Of Spotted Bass In The Wabash River, Evan C. Boone

Masters Theses

Spotted Bass Micropterus punctulatus Rafinesque are a popular sport fish primarily found in the streams and reservoirs of the south. The Wabash River, a large tributary of the Ohio River, contains a naturally reproducing population on the northern boundary of their range. Currently, the lower Wabash River is monitored using two different sampling designs, the Long Term Electrofishing Program monitors community assemblages using stratified random sampling whereas the Illinois Department of Natural Resources uses a fixed sampling design. Due to the wide distribution but low abundance of Spotted Bass throughout this drainage, captures from each design were compared to assess …

Functionalized Bodipy Dyes For Dye-Sensitized Solar Cells, Mahmoud A. Elkhalifa

Masters Theses

It is predicted that more than 20 terawatts of carbon-free energy will be demanded by 2050 to maintain a sufficient energy supply for the increasing global population, and photovoltaics are predicted to contribute significantly to the global energy needs. Dye-sensitized solar cells (DSCs) are an emerging class of photovoltaics (PV) that has produced promising power conversion efficiencies at low costs. Currently, electron recombination, dye aggregation, weak adsorption, and inefficient absorbance are among of the largest contributors to low DSC efficiencies.

BODIPY dyes are one of the most promising classes of dyes emerging for DSC application. These low molecular weight fluorophores …

Diel And Seasonal Patterns Of Channel Catfish Movement And Habitat Use In The Lower Wabash River, Hanna Gibbs Kruckman

Masters Theses

Channel catfish Ictalurus punctatus are commonly found throughout the Mississippi River basin and support commercial and recreational fisheries in many large river systems. Understanding population demographics as well as movement patterns and habitat usage can provide a more holistic approach to species management and conservation. Within a 16-km stretch of the lower Wabash River, 27 channel catfish were implanted with acoustic transmitters to monitor fine scale movement and habitat use from September 2014 through April 2016. Channel catfish were located using active tracking during two types of tracking events. Site tracking occurred only during daylight hours and diel tracking monitored …

The Recruitment Of Sexual Minority Students In Higher Education, Jorge El-Azar

Masters Theses

In a time when universities actively recruit diverse groups of applicants, some universities are seeing the need for a diverse student population and advancing their recruitment initiatives to recruit specific groups of students. The LGBTQ+ community has been perceived as an invisible community (Cegler, 2012) by some universities, but other higher education institutions are seeing the value of specifically recruiting students who identify as a part of this community. This study was designed to focus on the initiatives universities are implementing to effectively recruit students who identify as LGBTQ+. Using a qualitative approach, the researcher interviewed six participants who identified …

Stopover Ecology Of Neotropical Migratory Songbirds In The Northern Yucatan Peninsula, Mexico, Lauren E. Solomon

Masters Theses

Chapter I. Full-service hotels, convenience stores or fire escapes? Evaluating function of stopover sites for Neotropical migrants in the northern Yucatan Peninsula

Nearctic-Neotropical migratory songbirds incur the highest mortality rates during their annual migrations. Migratory songbirds use a network of stopover sites to rest, refuel, or seek refuge during times of poor weather conditions; and the time and energy expended at these sites exceeds that of migratory flight. In order to conserve stopover sites with the highest value to Neotropical migrants, a conceptual framework was developed to classify stop over sites into three functional categories based on their function for …

Development Of Learning Objectives For An Undergraduate Computer-Aided Drafting And Design Animation Using The Delphi Technique, Gavin M. Wilk

Masters Theses

This study reflects on learning objectives created for an advanced computer aided drafting (CAD) learning module(s) or course with the emphasis on simulation and engineering animations. These objectives were derived by using the Delphi technique by access the support of a panel of subject matter experts (SME) from academia and industry that are interested in CAD. The results of this study are intended for the use of creating instructional modules for undergraduate studies.

A panel of experts were chosen through an electronic listserv of engineering and technology supporters. Two rounds of two different Delphi survey instruments were utilized to complete …

Quantifying Bat Detection Survey Methods And Activity Patterns, Tara C. Hohoff

Masters Theses

Bats have an astonishing diversity and provide vital ecosystem services in an array of different niches. In North America, most species of bats are insectivores and tend to be frequently overlooked for their important ecosystem role providing insect control. As bat populations have declined in recent years, farmers, land managers, conservationists, and bat enthusiasts have wondered what we can do to protect our local bat populations. As a first step, we need to develop methods that more effectively survey for rare species of bats. By performing inefficient surveys, we are doing a disservice to our funding agencies providing misinformation that …

Impact Of Transcription Factors On Fibroblast Specific Gene Silencing In Somatic Cell Hybrids, Tania Ray

Masters Theses

As totipotent cells differentiate to specific cell types in multicellular organisms, certain sets of genes are turned off (gene silencing/gene extinction) while others are turned on (gene activation). Cell type specific gene silencing and gene activation is the basis of cell differentiation. Somatic cell hybrids which are produced by fusing different types of somatic cells from two different tissues have been used as a valuable resource to discern the phenomenon of lineage- specific gene extinction. Identification of regulatory factors that mediate gene extinction in hybrids are key to understanding regulatory mechanisms that govern cell differentiation in a multicellular organism. Transcription …
