Distinct Properties Underlie Flavin-Based Electron Bifurcation In A Novel Electron Transfer Flavoprotein Fixab From Rhodopseudomonas Palustris, H. Diessel Duan, Carolyn E. Lubner, Monika Tokmina-Lukaszewska, George H. Gauss, Brian Bothner, Paul W. King, John W. Peters, Anne-Frances Miller

Chemistry Faculty Publications

A newly recognized third fundamental mechanism of energy conservation in biology, electron bifurcation, uses free energy from exergonic redox reactions to drive endergonic redox reactions. Flavin-based electron bifurcation furnishes low-potential electrons to demanding chemical reactions, such as reduction of dinitrogen to ammonia. We employed the heterodimeric flavoenzyme FixAB from the diazotrophic bacterium Rhodopseudomonas palustris to elucidate unique properties that underpin flavin-based electron bifurcation. FixAB is distinguished from canonical electron transfer flavoproteins (ETFs) by a second FAD that replaces the AMP of canonical ETF. We exploited near-UV–visible CD spectroscopy to resolve signals from the different flavin sites in FixAB and to …

Parasite Component Community Of Smalltooth Sawfish Off Florida: Diversity, Conservation Concerns, And Research Applications, Micah D. Bakenhaster, Stephen A. Bullard, Stephen S. Curran, Delane C. Kritsky, Erin H. Leone, Lauren K. Partridge, Carlos F. Ruiz, Rachel M. Scharer, Gregg R. Poulakis

Faculty Publications

Compared with that of other charismatic elasmobranchs, the component community of metazoan parasites infecting endangered smalltooth sawfish Pristis pectinata is exceedingly poorly characterized: adults of Dermophthirioides pristidis and Neoheterocotyle inpristi (ectoparasitic flatworms of skin and gill, respectively) were the only confirmed parasites prior to the description, based on specimens reported herein, of Mycteronastes caalusi. Our opportune and directed parasitological examinations of 290 smalltooth sawfish (277 live inspections; 13 necropsies; 671 to 2640 mm stretch total length) in south Florida coastal waters revealed at least 8 species of Platyhelminthes, 9 of Arthropoda, 4 of Annelida, and 1 of Nematoda. This …

Hampton Roads Residents’ Preferences For Dune And Beach Management, Seth Parker, Donta Council, Makayla Brown

School of Public Service Faculty Publications

The management of dunes and beaches in Hampton Roads is critical to the region’s tourism industry and to provide protection from storms and flooding. During the summer of 2017, we surveyed over 675 residents of Hampton Roads to gauge their preferences for the management of dunes and beaches. An overwhelming majority felt that all taxpayers should have a say in maintenance practices along with government regulations to assist with the protection of beaches and dunes. Residents leaned towards localized input from citizens as preferred methods of management and understood the importance their tax dollars play in funding those methods. While …

Examining The Effectiveness Of A Therapist Training On The Reflective Exploration Of Parenting Interactions Tool, Molly Jean Winterrowd

Doctor of Psychology (PsyD)

The current study seeks to explore the impact of a therapist training on the Reflective Exploration of Parenting Interactions Tool (REPIT, Verona, 2015), a clinical, therapist-guided exercise that aims to improve parent insight, and in turn, facilitate a decrease in parent-child conflict. The REPIT was created as a therapy exercise in which parents are guided through a series of 19 standardized questions that build their insight into their own internal processes regarding conflict with their child. Specifically, the reflection encourages exploration of how the parental internal processes impact the parent-child relationship and interact with the child thought processes to create …

Semi-Synthesis Of A Novel Library Of Alkaloids As Potential Selective Analgesics, Brittany M. Gallagher

Theses and Dissertations

Semi-synthetic compounds are an important part of the therapeutic drug discovery process. The goals of the project were to synthesize different generations of matrine analogues in order to gain many opportunities to manipulate the core structure. The long-term goal was, by manipulating the structure, the possibility to increase the biological activity of the original compound while also decreasing the toxicity. The first-generation matrine analogue allows for a synthesis similar to the Striker reaction producing aminonitriles. An alkyne coupling reaction was also possible with the modification, producing propargyl-amines. Both of the reactions resulted in the addition of a triple bond substituent …

Reference Gene Selection For Rt-Qpcr Analysis In Harmonia Axyridis, A Global Invasive Lady Beetle, Xiaowei Yang, Huipeng Pan, Ling Yuan, Xuguo Zhou

Entomology Faculty Publications

Harmonia axyridis is a voracious predator, a biological control agent, and one of the world most invasive insect species. The advent of next-generation sequencing platforms has propelled entomological research into the genomics and post-genomics era. Real-time quantitative PCR (RT-qPCR), a primary tool for gene expression analysis, is a core technique governs the genomic research. The selection of internal reference genes, however, can significantly impact the interpretation of RT-qPCR results. The overall goal of this study is to identify the reference genes in the highly invasive H. axyridis. Our central hypothesis is that the suitable reference genes for RT-qPCR analysis …

Prevention Of Post Intensive Care Syndrome-Family With Sensation Awareness Focused Training Intervention: A Randomized Controlled Trial Pilot Study, Paula L. Cairns

USF Tampa Graduate Theses and Dissertations

Post Intensive Care Syndrome-Family (PICS-F) refers to acute and chronic psychological effects of critical illness on family members of patients in intensive care units (ICU). Evidence about the increase and persistence of PICS-F warrants the need for prevention interventions. This study evaluated the feasibility of providing Sensation Awareness Focused Training (SĀF-T) during the ICU stay for spouses of mechanically ventilated patients. Methods: A randomized controlled trial of SĀF-T versus a control group was conducted (n=10) to assess safety, acceptability, feasibility, and effect size of the intervention on PICS-F symptoms. Symptoms assessed as outcome measures included stress, anxiety, depression, posttraumatic stress …

When Should Rights "Trump"? An Examination Of Speech And Property, Laura S. Underkuffler

Maine Law Review

In his well-known article, Property, Speech, and the Politics of Distrust, Professor Richard Epstein—a leading contemporary voice in the fields of property theory and constitutional law—makes a simple but compelling argument. There has been, he argues, a mistake in “the dominant mode of thinking about property rights during the past fifty years [that] has been ... of constitutional dimensions.” This mistake, in Professor Epstein's view, is the refusal of the federal courts to accord to individual property rights the same kind of protection from government regulation that is accorded to other constitutional rights. Using free speech as his example, Professor …

The Bee, A Natural History, By Noah Wilson-Rich (2014, Princeton University Press. Isbn: 9780691161358. Us$27.95), Gard W. Otis Dr.

The Great Lakes Entomologist

(excerpt)

Upon receiving “The Bee, A Natural History”, by Noah Wilson Rich, I was drawn in by the title and the beautiful rust and grey front cover featuring a nearly 3-D photo of a honey bee. I immediately felt twinges of excitement—this is the book I have always wanted to have available for my university course, Apiculture and Honey Bee Biology—and disappointment—I did not write it! The “bee”— singular—accompanied by the high-resolution photo, suggested that this book focused on the world’s best understood insect that my course is centered around, Apis mellifera.

First Record Of The Arid-Land Termite, Reticulitermes Tibialis Banks, In Wisconsin, Rachel A. Arango

The Great Lakes Entomologist

During a survey of termites in Wisconsin, one colony was found from a different habitat than the remaining populations. This observation led to further genetic testing which resulted in a determination of Reticulitermes tibialis Banks. This is the first record of a termite species other than Reticulitermes flavipes (Kollar) to be established in the state.

Regional Caddisfly (Trichoptera) Indicator Species For Mid-Order Michigan And Minnesota Streams, David C. Houghton

The Great Lakes Entomologist

Nearly 150,000 caddisfly specimens representing 238 species were analyzed from 166 5–15m wide streams within Michigan and Minnesota to deter- mine the characteristic indicator species of 5 previously-established regions of caddisfly biological diversity. Based on a combination of relative frequency and abundance, 35 of these species indicated a particular region or regions. Indicator species in forested regions constituted a balance of trophic functional groups, whereas indicator species from agricultural regions were dominated by filtering collectors. While it was difficult to determine if species were indicating natural habitat type or differences in anthropogenic disturbance, establishing indicator species now will render potential …

How Did E. M. Walker Measure The Length Of The Labium Of Nymphs Of Aeshna And Rhionaeschna (Odonata: Aeshnidae)?, Robert B. Dubois, Kenneth J. Tennessen

The Great Lakes Entomologist

The exhaustive studies of nymphs of Aeshna Fabricius and Rhionaeschna Förster by E. M. Walker (1912-1958) have long guided the taxonomy of these groups and formed the basis for keys still in use today. However, uncertainty about how he measured the length of the labium, including the varied terminology he used over the duration of his career concerning this structure, has led to confusion about application of his taxonomic recommendations. We recalculated ratios of the maximum width/length [W(max)/L] by measuring the illustration dimensions of folded labia and prementums in publications throughout his career and compared these data with the ratios …

Phenological Attributes And Phylogenetic Relationships Of Rhagoletis Juniperina Marcovitch (Diptera: Tephritidae) In The Great Lakes Region, Megan Frayer, Daniel Hulbert, Serdar Satar, James J. Smith

The Great Lakes Entomologist

Rhagoletis juniperina Marcovitch (Diptera: Tephritidae) infests Eastern Red Cedar (Juniperus virginiana L.) and other North American junipers. While several Rhagoletis species are of interest as orchard crop pests (apple maggot, blueberry maggot, cherry fruit fly) and as models for studying speciation (R. pomonella Walsh species group), R. juniperina is of interest because it may tie together evolutionarily the Nearctic and Palearctic Rhagoletis fauna. One goal of this study was to test two competing hypotheses first proposed by Bush (1966): i) that R. juniperina is more closely related to the Nearctic dogwood- infesting R. tabellaria (Fitch), to which it …

Comparison Of Different Trap Colors And Types For Capturing Adult Agrilus (Coleoptera: Buprestidae) And Other Buprestids, Toby R. Petrice, Robert A. Haack

The Great Lakes Entomologist

Numerous research studies have focused on the development of effective traps for surveying and monitoring for emerald ash borer, Agrilus planipennis (Fairmaire) (Coleoptera: Buprestidae), since it was discovered in North America. However, little attention has been placed on developing effective traps for monitoring and surveying other Agrilus and Buprestidae. In 2009–2011, we conducted several studies to test the attractiveness of different trap colors and types of sticky traps to Agrilus and other Buprestidae. We found green (peak reflectance: 530–536 nm, 57.6%) sticky traps that consisted of custom colored corrugated plastic, and were coated with insect trapping glue to be the …

Survival And Phenology Of Agrilus Planipennis (Coleoptera: Buprestidae) Reared On A Newly Developed Artificial Diet Free Of Host Material, Melody A. Keena, Hannah Nadel, Juli Gould

The Great Lakes Entomologist

The final phase in the development of an artificial diet that contains no ash host material and the phenology of the emerald ash borer, Agrilus planipennis Fairmaire (Coleoptera: Bupresidae) on that diet are documented. A diet containing powdered ash phloem exists, but host material introduces potential variability and contamination, and the cost and effort needed to collect and process it can be high. The post-embryonic development of A. planipennis was evaluated on four artificial diets lacking host material, and effects of variations in diet layer thickness and moisture content were also investigated. The best diet and rearing method resulted in …

Nocturnal Flight Periodicity Of The Caddisflies (Trichoptera) In Forest And Meadow Habitats Of A First Order Michigan Stream, Kiralyn Brakel, Lydia R. Wassink, David C. Houghton

The Great Lakes Entomologist

Using ultraviolet light traps, over 5000 caddisfly specimens were collected from a forest and a meadow habitat of Fairbanks Creek in northern Lower Michigan. Samples were collected every 15 minutes, interspersed with 15 minutes of no sampling, from sunset to sunrise during 5 nights from late June to mid-July 2014. Despite having fundamentally different caddisfly assemblages dominated by different species, mean specimen abundance and mean species richness in both habitats exhibited similar trends: peaking between 22:30 and 23:00, decreasing until 02:00 or 02:30, increasing again slightly during the later morning periods, and then decreasing to near zero by 06:00. On …

Movement Patterns Of Carabid Beetles Between Heterogenous Crop And Noncrop Habitats, Heather Russon, J. Megan Woltz

The Great Lakes Entomologist

Habitats adjacent to crop fields can increase natural enemy populations by providing additional food, shelter and overwintering sites. While many studies have focused on the role of non-crop borders for supporting natural enemies, here we investigate the influence of adjacent crop habitats as well. We monitored the movement of carabid beetles (Coleoptera: Carabidae) between wheat fields and adjacent crop and non-crop habitats using bi-directional pitfall traps. We found greater movement of carabids from corn into wheat fields than from forest and soybean, with intermediate levels of movement from roadside vegetation. Additionally, significantly more carabids were captured moving into corn from …
