Selection Dynamics In Heliconius Hybrid Zones And The Origin Of Adaptive Variation, Steven Grant Shaak Dec 2015

Selection Dynamics In Heliconius Hybrid Zones And The Origin Of Adaptive Variation, Steven Grant Shaak

Theses and Dissertations

There is repeated evidence that hybridization is a major contributor to the production of adaptive diversity; however, the evolutionary fate of hybrids in natural populations remains poorly understood. In Heliconius butterflies, hybridization is common and responsible for generating a variety of warning color patterns across the genus. Predator avoidance of warning colorations appears to largely be learned, which drives strong positive frequency-dependent selection. This creates a paradox for hybrid lineages: how do novel hybrid forms manage to establish and persist under such strong selection? In this dissertation, I present a series of studies centered on the selection dynamics of Heliconius …

The Evaluation Of Adsorbents For The Removal Of Aflatoxin M1 From Contaminated Milk, Erika D. Womack Dec 2015

The Evaluation Of Adsorbents For The Removal Of Aflatoxin M1 From Contaminated Milk, Erika D. Womack

Theses and Dissertations

Taking precautions to restrain aflatoxin M1 (AFM1) from milk is critical, particularly due to the health and economic impact AFM1 imposes. The predominant post-harvest means of reducing AFM1 in milk includes the addition of sequestering agents to feed to diminish the bioavailability of aflatoxin B1 (AFB1), the parent compound of AFM1 found in contaminated feed. Still, residual AFM1 has been found in the milk. Using sequestering agents added to raw milk, we found that activated carbon was the most effective binder to reduce AFM1 contamination. The combination of 0.75% granular activated carbon (GAC) and a flow rate of 0.4 mL/min …

Synthesis And Catalytic Activity Of -Nhc Group 9 Metal Pincer Complexes, Sean William Reilly Dec 2015

Synthesis And Catalytic Activity Of -Nhc Group 9 Metal Pincer Complexes, Sean William Reilly

Theses and Dissertations

N-Heterocyclic carbenes (NHCs) are one of the few ligand systems that can finely tune transition metal catalysts via sterics and electronics. The strong sigma-donating properties of these ancillary ligands allow the development of robust tridentate NHC pincer framework, which has emerged as an alternative to the phosphine pincer ligands. The combination of NHC and pincer systems has resulted in a new generation of catalytically active organometallic complexes reported throughout the literature. -NHC Rh pincer complexes were found to be catalytically active in C-C and C-B bond formation via 1,4dition reactions. In addition, the in-situ generated -NHC Ir(H) pincer complex demonstrated …

Is The Zebrafish Zombie Mutant Caused By A Mutation In Cdc20?, Peyton Johnston Dec 2015

Is The Zebrafish Zombie Mutant Caused By A Mutation In Cdc20?, Peyton Johnston

Honors Theses

The zombie mutant was identified as an early arrest mutant, stopping in development around the 10-somite stage (14 hours of development). Further inspection revealed that this mutant was a cell cycle mutant and cells in the mutant arrest during metaphase as early as the 5-somite stage (11.6 hours of development). A similar phenotype is seen in the Drosophila melanogaster cell cycle gene fizzy, known to be to be a homolog of the Saccharomyces cerevisiae gene, cell division cycle 20 (cdc20). CDC20 is an activator protein of the anaphase promoting complex/cyclosome (APC/C), an ubiquitin E3 ligase that is …

Recommendations For The Development Of New Hospital Guidelines Due To The Effects Of Antibiotics On Clostridium Difficile Colitis, Megan Kohsel Dec 2015

Recommendations For The Development Of New Hospital Guidelines Due To The Effects Of Antibiotics On Clostridium Difficile Colitis, Megan Kohsel

Honors Theses

Clostridium difficile colitis is an infection that causes inflammation of the colon and diarrhea. This can even lead to death in some cases. The incidence of this infection and its overall effects have been on the rise throughout the last twenty years as antibiotics have been prescribed more frequently. Therefore, it is necessary that the rate of C. difficile infection is lowered by improved guidelines for hospitals, so that fewer people are infected and also that fewer antibiotics are prescribed to avoid the infection with C. difficle.

Experiential Avoidance Post-Trauma: Investigating Predictors Of Traumatic Stress And Problematic Behavior., Elise Trim Dec 2015

Experiential Avoidance Post-Trauma: Investigating Predictors Of Traumatic Stress And Problematic Behavior., Elise Trim

Honors Theses

Experiential avoidance (EA) is the unwillingness to remain in contact with distressing thoughts, feelings, memories, and other private experiences (Hayes et al., 2004; Hayes, Strosahl, & Wilson, 1999). Although the use of EA may lead to immediate reductions in distress, prolonged use can result in problem behaviors such as substance misuse (Hayes, Wilson, Gifford, Follette, & Strosahl, 1996). Although a strong temporal relationship has yet to be established, findings suggest a possibility that EA could be a mechanism by which posttraumatic stress disorder (PTSD) symptoms are developed and maintained (Krause, Mendelson, & Lynch, 2003; Rosenthal, Polusny, & Follette, 2006; Dvorak, …

A Note On The Scorpions From The Pirin Mountains, Southwestern Bulgaria (Scorpiones: Buthidae, Euscorpiidae), Rolando Teruel, Victor Fet, Luis F. De Armas Dec 2015

A Note On The Scorpions From The Pirin Mountains, Southwestern Bulgaria (Scorpiones: Buthidae, Euscorpiidae), Rolando Teruel, Victor Fet, Luis F. De Armas

Euscorpius

In the present note, four scorpion species are recorded from the Pirin Mountains in southwestern Bulgaria, including the first records for Bulgaria of both Mesobuthus gibbosus (Brullé, 1832) (Buthidae) and the “mingrelicus complex” of the genus Euscorpius Thorell, 1876 (Euscorpiidae) (the latter based upon an undetermined species). Also, E. hadzii Caporiacco, 1950 and another undetermined species of Euscorpius belonging to the “carpathicus complex” are recorded from Pirin. The taxonomic affinities of the taxa are discussed, as well as some biogeographical considerations about the scorpions of this poorly studied mountainous area.

Alloscorpiops Wongpromi Sp. N. From Thailand And Laos (Scorpiones: Euscorpiidae: Scorpiopinae), František Kovařík, Michael E. Soleglad, Ondřej Košulič

Euscorpius

Alloscorpiops wongpromi sp. n. from Thailand and Laos is described and compared with all other species of the genus Alloscorpiops Vachon, 1980. A key is presented to all species of the genus. A. wongpromi sp. n. is characterized mainly by a higher number of trichobothria on the patella, which has 33–37 external and 21–22 ventral trichobothria, and a dark-colored telson. The subgenus Laoscorpiops Lourenço, 2013 is synonymized with the nominotypical subgenus, because it was based on misinterpretation of the trichobothrial pattern, with two ventral accessory trichobothria on the chela regarded as part of the external Eb series.

Response Of Male Centruroides Vittatus (Scorpiones: Buthidae) To Aerial And Substrate-Borne Chemical Signals, Steffany B. Steinmetz, Karen C. Bost, Douglas D. Gaffin Dec 2015

Response Of Male Centruroides Vittatus (Scorpiones: Buthidae) To Aerial And Substrate-Borne Chemical Signals, Steffany B. Steinmetz, Karen C. Bost, Douglas D. Gaffin

Euscorpius

Chemical signaling promotes mate location throughout numerous animal taxa. In this study we investigated the possibility that striped scorpions, Centruroides vittatus, use chemical signaling in the form of odor plumes or substrate-borne deposits as communication channels. A Y-shaped arena was constructed to test scorpions’ use of air-borne chemical cues in the detection of potential mates. A second, circular behavioral choice chamber was used to test male scorpions’ responses to female deposits by direct substrate contact. Male scorpions showed no tendency to move toward the female in tests of air-borne chemical transmission but they did demonstrate behavior associated with chemical …

A Powerful New Light Source For Ultraviolet Detection Of Scorpions In The Field, Graeme Lowe, Steven R. Kutcher, Doug Edwards Dec 2015

A Powerful New Light Source For Ultraviolet Detection Of Scorpions In The Field, Graeme Lowe, Steven R. Kutcher, Doug Edwards

Euscorpius

We describe a new portable solid-state ultraviolet (UV) light that should greatly improve the ease and effectiveness of fluorescent detection of scorpions in the field. The design is based on an array of InGaN light emitting diodes (LEDs). It is in-expensive, lightweight, simple to implement, energetically efficient and mechanically rugged. Scorpion cuticular fluorescence excited by an LED array is 13-fold brighter than excitation by previously available fluorescent tube lamps drawing the same current from the battery.

Gender And General Strain Theory: An Examination Of The Role Of Gendered Strains And Negative Emotions On Crime, Aaron Michael Puhrmann Dec 2015

Gender And General Strain Theory: An Examination Of The Role Of Gendered Strains And Negative Emotions On Crime, Aaron Michael Puhrmann

Open Access Dissertations

One of the predominant issues in the criminological study of gender and crime is the gender gap in crime. Women are much less involved in crime than men and are involved with different types of crimes. By integrating gender-specific theory with General Strain Theory (GST), this dissertation provides an explanation of female crime and the gender gap in crime. Gendered General Strain Theory (gendered-GST) argues that gender differences in negative life events (strains) and differences in negative emotions lead to distinct pathways to criminal offending. This dissertation empirically examines the different propositions of gendered-GST and whether they adequately explain female …
