Step By Step: Biology Undergraduates' Problem-Solving Procedures During Multiple-Choice Assessment, Luanna B Prevost, Paula P Lemons
Integrative Biology Faculty and Staff Publications
This study uses the theoretical framework of domain-specific problem solving to explore the procedures students use to solve multiple-choice problems about biology concepts. We designed several multiple-choice problems and administered them on four exams. We trained students to produce written descriptions of how they solved the problem, and this allowed us to systematically investigate their problem-solving procedures. We identified a range of procedures and organized them as domain general, domain specific, or hybrid. We also identified domain-general and domain-specific errors made by students during problem solving. We found that students use domain-general and hybrid procedures more frequently when solving lower-order …
A Morphological, Functional, And Genetic Investigation Of The Male Compound Eye Phenotype Of Chrysomya Megacephala (Diptera: Calliphoridae)), Joshua Smith
FIU Electronic Theses and Dissertations
A very unique compound eye in dipterans is found in males of the forensically important blow fly, Chrysomya megacephala (Diptera: Calliphoridae). This compound eye is characterized by an area of enlarged dorsal facets that, unlike almost all other regional changes in dipteran ommatidia size, is not accompanied by a change in resolution. This region is believed to play a role in mate tracking and allow for increased light capture, though no behavioral studies have tested these claims. An initial goal of the dissertation was to examine the function of this compound eye. Using allometric measurements coupled with behavioral tests, I …

Studying The Effects Of Serpentine Soil On Adapted And Non-Adapted Species Using Arduino Technology, Kiana Saniee, Edward Himelblau, Brian Paavo
STAR Program Research Presentations
Abstract: Serpentine soils are formed from ultramafic rocks and are represent an extreme environment for plants. Serpentine soils are unique in that they carry high concentrations of heavy metals, are nutrient deficient, particularly in calcium, and have poor water retention capabilities. Although these soils constitute harsh conditions for plant growth, there are a number of species that are adapted and even endemic to serpentine soil. Water retention by commercial potting mix was compared with serpentine soil. Also, serpentine adapted and non-adapted species were grown in both soil treatments and physiological data were collected. We used the Arduino electronic platform to …

The aryl hydrocarbon receptor (AHR) was for many years of interest only to pharmacologists and toxicologists. However, this protein has fundamental roles in biology that are being revealed through studies in diverse animal species. The AHR is an ancient protein. AHR homologs exist in most major groups of modern bilaterian animals, including deuterostomes (chordates, hemichordates, echinoderms) and the two major clades of protostome invertebrates [ecdysozoans (e.g. arthropods and nematodes) and lophotrochozoans (e.g. molluscs and annelids)]. AHR homologs also have been identified in cnidarians such as the sea anemone Nematostella and in the genome of Trichoplax, a placozoan. Bilaterians, cnidarians, and …

Anaerobic Co-Digestion Of Chlorella Vulgaris And Dairy Whey For Enhanced Methane Production, Paula Drouin Ms
All Student Scholarship
The anaerobic digestion process is an additional step that can be implemented at wastewater treatment facilities for the production of biogas (i.e. methane) that can be used to generate energy and significantly reduce the facility's energy cost. An emerging area of interest with anaerobic digestion is the inclusion of high-strength degradable organic waste (in addition to wastewater solids) that can lead to increased methane production by methanogens. Chlorella vulgaris (C. vulgaris), a species of green microalgae, is ubiquitous green alga often present at water-water treatment plants. I investigated its usefulness in an existing wastewater treatment process. Two investigations …

The CRISPR-Cas system is an adaptive immune system found in bacteria which helps protect against the invasion of other microorganisms. This system induces double stranded breaks at precise genomic loci (1) in which repairs are initiated and insertions of a target are completed in the process. This mechanism can be used in eukaryotic cells in combination with sgRNAs (1) as a tool for genome editing. By using this CRISPR-Cas system, in addition to the “safe harbor locus,” ROSAβ26, the incorporation of a target gene into a site that is not susceptible to gene silencing effects can be achieved through few …
Effects Of Soil Erosion Barriers On Percent Cover And Sediment Size, Michael Perez
Effects Of Soil Erosion Barriers On Percent Cover And Sediment Size, Michael Perez
STAR Program Research Presentations
Ranching began on Santa Rosa Island in the 1840’s, introducing nonnative megafauna that put selective grazing pressures on endemic species. Dense groves of island oak (Q. tomentella) are aid in sediment deposition and retention. A current restoration effort, involved installing soil erosion barriers, known as wattles, to prevent sediment from being lost upslope and recruit plant growth whose root systems could further stabilize the slope. This experiment was designed to compare percent cover of vegetation growth in areas with and without soil erosion barriers. This was done using the line intercept method (n=42) on three meter transects, measuring …
The Influence Of Peer-Led Team Learning On Underrepresented Minority Student Achievement In Introductory Biology And Recruitment And Retention In Science, Technology, Engineering, And Mathematics Majors, Jeremy David Sloane
Dissertations - ALL
Increasing underrepresented minority (URM) participation in science, technology, engineering, and mathematics (STEM) is of increasing national importance as the United States continues to fall behind other nations in global economic competitiveness. These students constitute a large pool of potential STEM majors at the college level, but they have been recruited to and retained in STEM programs at significantly lower rates than students from other populations. As such, President Barack Obama’s President’s Council of Advisors on Science and Technology (PCAST) has called on undergraduate science instructors to diversify their teaching methods and employ active learning strategies to improve students’ success in …
The Function Of Renalase, Brett Allen Beaupre
The Function Of Renalase, Brett Allen Beaupre
Theses and Dissertations
Renalase was originally reported to be an enzyme secreted into the blood by the kidney to lower blood pressure and slow heart rate. Despite multiple reports claiming to confirm this activity in vivo there has been considerable discord in regards to the reaction catalyzed by renalase. The structural topology of renalase resembles that of known flavoprotein oxidases, monooxygenases and demethylases, but the conserved active site residues are unique to renalase. It has been reported that the catalytic function of renalase is to oxidize circulating catecholamines, however in vitro studies have failed to demonstrate a catalytic activity in the presence of …

Individual Movement Rates Are Sufficient To Determine And Maintain Dynamic Spatial Positioning Within Uca Pugilator Herds, Eilea R. Knotts
Theses and Dissertations
Spatial location within aggregations (i.e. periphery, central) is of biological significance to gregarious animals. Because these positions are a potential consequence of consistent individual behavioral differences, or personality, a better understanding of potential mechanisms concerning personality is central to predicting an individuals’ location. To determine the effects of individual personality on the dynamic spatial positioning of Uca pugilator while herding, field data collection and agent-based modeling were employed. Individuals were assayed to establish their personalities and returned to the field for observation as a means of identifying location preference within selfish herds. There was a significant difference between the extreme …

Confirmation Of The Function Of Mrub1080 As Γ-Glutamyl Kinase (Prob) In Meiothermus Ruber, Cale J. Mccormick, Dr. Lori Scott
Celebration of Learning
This project is part of the Meiothermus ruber genome analysis project, which uses wet lab procedures and computational analysis to gather evidence of orthologous genes between Escherichia coli and Meiothermus ruber. In previous work, bioinformatics evidence supported the hypothesis that the gene Mrub1080 was an ortholog of E. coli proB. We investigated the biological function of Meiothermus ruber genes proB and proBA using the complementation assay. However, functional analysis proved inconclusive. For this particular research project, we confirmed that weakly complementing E. coli proB- null strains actually contained the desired M. ruber proB and proBA genes (inserted into a pKt1 …

Undergraduate introductory biology courses are changing based on our growing understanding of how students learn and rapid scientific advancement in the biological sciences. At Iowa State University, faculty instructors are transforming a second-semester large-enrollment introductory biology course to include active learning within the lecture setting. To support this change, we set up a faculty learning community (FLC) in which instructors develop new pedagogies, adapt active-learning strategies to large courses, discuss challenges and progress, critique and revise classroom interventions, and share materials. We present data on how the collaborative work of the FLC led to increased implementation of active-learning strategies and …

Regulation Of Ampa-Type Glutamate Receptor Homolog Glr-1 By Erad Ubiquitin Ligases In C. Elegans, Sam Witus
Scholars Week
Endoplasmic reticulum-associated degradation (ERAD) maintains cellular health by removing misfolded proteins from the endoplasmic reticulum (ER). ERAD is ubiquitin-dependent, and ubiquitination of target proteins can be catalyzed by ER-resident E3 ubiquitin ligases. In C. elegans, genes for three putative ERAD E3 ubiquitin ligases have been identified: hrd-1, hrdl-1, and marc-6 (HRD-1, GP78/AMFR, and MARCH-6 in mammalian systems). In C. elegans, these three genes cooperate to maintain the overall health of animals during ER stress. We are testing the roles of hrd-1, hrdl-1, and marc-6 in the neurons of C. elegans. GLR-1 is a glutamate receptor that is expressed in a …

Cholesterol is carried and transported through bloodstream by lipoproteins. There are two types of lipoproteins: low density lipoprotein, or LDL, and high density lipoprotein, or HDL. LDL cholesterol is considered “bad” cholesterol because it can form plaque and hard deposit leading to arteries clog and make them less flexible. Heart attack or stroke will happen if the hard deposit blocks a narrowed artery. HDL cholesterol helps to remove LDL from the artery back to the liver.
Traditionally, particle counts of LDL and HDL plays an important role to understanding and prediction of heart disease risk. But recently research suggested that …
Ocean Acidification And Predator-Prey Relations: Correlating Disruption Of Predator Avoidance With Chemosensory Deficits, Alexandra Fw Sidun, William G. Wright
Ocean Acidification And Predator-Prey Relations: Correlating Disruption Of Predator Avoidance With Chemosensory Deficits, Alexandra Fw Sidun, William G. Wright
Student Scholar Symposium Abstracts and Posters
One of the most destructive effects of global climate change is the increased carbon sequestering and consequential acidification of our world’s oceans. The impacts of ocean acidification on marine organisms are still relatively unknown, especially effects on behavioral ecology. Avoiding predation has emerged from recent behavioral ecology literature as a critical feature in the life history of a wide array of animal species; experiments on marine fishes suggest acidic water compromises their predator-avoidance abilities. Recent assays in our lab suggest predator-induced behavior is reduced by weakly acidic water. These experiments do not address the potential factor of generalized malaise caused …

This study aims to establish the level at which University of Nebraska-Lincoln students reason with simple relationships in the context of cellular respiration at the levels of glycolysis, Krebs cycle, and electron transport chain. These processes are component processes of cellular respiration and each has multiple inputs and outputs. 633 student consented for this study, from which 18 student models were randomly selected, processed, and analyzed. Classroom observations were used to determine structures and relationships that were inputs and outputs to the three processes. In their models, students did not include different numbers of input or outputs when describing glycolysis, …
Neurotoxicity Of Two Related Organophosphates On Caenorhabditis Elegans, Collin M. Brown
Neurotoxicity Of Two Related Organophosphates On Caenorhabditis Elegans, Collin M. Brown
Honors Program Projects
Organophosphates are a class of toxicants that act by inhibiting the activity of acetylcholinesterase, an enzyme vital to normal neuronal activity. Dimethoate and omethoate are two organophosphates that are chemical "cousins" of one another. Omethoate is a metabolite, or byproduct of dimethoate decomposition, and is more toxicologically active than dimethoate. Both toxicants were applied to cultures of Caenorhabditis elegans to determine two qualities of the organophosphates: their relative toxicity and their cumulative effects. The toxicity of omethoate was found to be significantly higher than that of dimethoate. Omethoate was found to have a 144.4% more lethal toxicity than dimethoate, and …
Effect Of Bisphenol-A On Neurodevelopment In Drosophila Melanogaster Larvae, Alexandra M. Streifel
Effect Of Bisphenol-A On Neurodevelopment In Drosophila Melanogaster Larvae, Alexandra M. Streifel
All College Thesis Program, 2016-2019
This paper examines the effects of the chemical preservative bisphenol-A on the developing nervous systems of Drosophila melanogaster, or fruit fly, larvae. This study examines the effects of bisphenol-A using both behavioral as well as morphological paradigms. It was determined that bisphenol-A significantly increased the amount of time larvae spent in seeking behavior, the number of peristaltic contractions, and the distance traveled in a linear fashion. In the morphological analysis, indications of increased dendritic area in experimental larvae existed, but there was not enough data to determine significance. For future research, it is recommended that more data be gathered to …

Evaluating College Biology Laboratory Accommodations For Students With Blindness And Visual Impairments, Barbara Rae Heard
All Theses And Dissertations
Studies show that active participation in science laboratory activities promotes student learning. However, students with blindness and visual impairments (BVI) often confront obstacles to active participation in the required activities of the college biology laboratory. Legislation requires institutions of higher education to provide accommodations for students with disabilities, yet the institutions must also maintain the academic integrity of their courses and programs. While college biology instructors provide specific accommodations, such as tactile models and audible devices, to enable active participation by students with BVI, they do so without research-supported guidelines for best practices. This mixed methods study sought to evaluate …
