A Mixed-Methods Study Of Entomology Incorporation In U.S. Secondary Science Instruction, Erin M. Ingram

Department of Entomology: Dissertations, Theses, and Student Research

To encourage understanding and appreciation of insects, entomology education advocates have supported and encouraged K-12 teachers to integrate insects and insect-related content into formal science instruction. However, research examining how and why science teachers incorporate entomology into secondary science courses is limited.

A sequential explanatory mixed-methods research study was conducted to address this gap. The study was conducted in two phases. During the first phase, quantitative survey research was conducted with a representative sample of 254 U.S. secondary life science teachers. During the subsequent qualitative phase, follow-up interviews were conducted with a purposeful sample of 18 survey participants and an …

The Cancer Stem Cell Marker Gsk3b, A Gene Involved In Oxidative Stress, Modulates Chemoresistance In Ovarian Cancer, Noelle L. Cutter Ph.D., Julia Fiederlein, Brianna Mcnulty, Cassandra Greco, Kimberly Doyle

Faculty Works: Biology, Chemistry, and Environmental Studies

The leading cause of death from gynecologic malignancies is epithelial ovarian cancer. These tumors are comprised of a highly heterogeneous population of cells, of which only a small subset of stem-like cells possess the ability to regenerate tumors in vivo. These cancer stem cells (CSCs) represent a significant clinical challenge as they are resistant to conventional cancer therapies and play essential roles in metastasis and tumor relapse. While chemotherapy is the preferred treatment modality, chemoresistance severely limits treatment success. It has been hypothesized that cancer stem cells are at the root of this problem. Their ability to self-renew and proliferate …

Science and Technology Department Faculty Journal Articles

Heterotrophic protists play pivotal roles in aquatic ecosystems by transferring matter and energy, including lipids, from primary producers to higher trophic predators. Using Oxyrrhis marina as a model organism, changes to the non-saponifiable protist lipids were investigated under satiation and starvation conditions. During active feeding on the alga Cryptomonas sp., the O. marina hexane soluble non-saponifiable fraction lipid profile reflected its food source with the observed presence of long chain mono-unsaturated fatty alcohols up to C25:1. Evidence of trophic upgrading in O. marina was observed with long chain mono-unsaturated fatty alcohol accumulation of up to C35:1. To the best of …

Traffic Noise And Sexual Selection: Studies Of Anthropogenic Impact On Bird Songs And Undergraduate Student Reasoning Of Evolutionary Mechanisms, Sarah Spier

School of Natural Resources: Dissertations, Theses, and Student Research

Humans have transformed much of the natural landscape and are continuing to do so at an accelerated rate, compromising natural areas that serve as important habitat for many species. Roads impact much of the environment as they fragment habitat and introduce traffic noise into the acoustic environment, deferentially affecting wildlife in roadside habitat. I explored how traffic noise affects the detection of birds based on whether their vocalizations were masked by traffic noise. Masked species detection was not affected by an increase in traffic noise amplitude, while there was a negative effect of traffic noise amplitude on unmasked species detection, …

Long-Billed Curlew Nest Site Selection And Success In The Intermountain West, Stephanie E. Coates, Benjamin W. Wright, Jay D. Carlisle

Intermountain Bird Observatory Publications and Presentations

Grassland birds have experienced steeper population declines between 1966 and 2015 than any other bird group on the North American continent, and migratory grassland birds may face threats in all stages of their annual cycle. The grassland‐associated long‐billed curlew (Numenius americanus) is experiencing population declines in regional and local portions of their North American breeding range. The nesting period is an important portion of the annual cycle when curlews may face demographic rate limitations from a suite of threats including predators and anthropogenic disturbance. We compared nest sites to random sites within breeding territories to examine nest site …

Electrostatically Localized Proton Bioenergetics: Better Understanding Membrane Potential, James Weifu Lee

Chemistry & Biochemistry Faculty Publications

In Mitchell's chemiosmotic theory, membrane potential Δψ was given as the electric potential difference across the membrane. However, its physical origin for membrane potential Δψ was not well explained. Using the Lee proton electrostatic localization model with a newly formulated equation for protonic motive force (pmf) that takes electrostatically localized protons into account, membrane potential has now been better understood as the voltage difference contributed by the localized surface charge density ([H-⁺_L] + ⁿΣ _i=1 [M⁽ⁱ⁺⁾_L]) at the liquid-membrane interface as in an electrostatically localized protons/cations-membrane-anions capacitor. That is, the origin of membrane …

Dna Methods To Understand Genetic Variation Of The Mola Mola Populations In And Near Cape Cod, Jessica Barros

Honors Program Theses and Projects

The ocean sunfish Mola mola is a frequent summer visitor to the waters off of Southeastern Massachusetts and Cape Cod. In late fall, water temperatures drop and some animals strand on area beaches. Stranded animals provide an easily available source of DNA to study the population genetics of this species with the specific goal to learn about genetic variation within and between individuals in this population. This study will continue to identify and characterize microsatellite repeat regions that will be used to study genetic variation. Four new microsatellite regions have been identified and amplified using polymerase chain reaction conditions that …

The Effects Of Meloidogyne Incognita On Jaz1, Jaz12, And Jaz13 Gene Expression In Arabidopsis, Emily Green

Honors Program Theses and Projects

Meloidogyne incognita, a root-knot nematode (RKN), poses a threat to the well-being of the global agricultural industry. These endoparasites rely on plant roots and drain nutrients from crops intended for human or livestock consumption. Root knot nematodes cost the agricultural industry billions of dollars in lost crops each year and threaten efforts to meet the growing demand for food. Though plants are susceptible to dangers, such as these parasites, many have evolved defense and/or repair mechanisms to compensate for this vulnerability. The goal of this research is to study one gene family involved in such defenses. Specifically, I studied the …

Bringing Science To Life In The Fifth-Grade Classroom Through Hands-On Learning, Kelly Gately

Honors Program Theses and Projects

Science helps provide insight into the unknown and provides an outlet for exploration of living things. Children are innately curious about how thing work, and they are eager to ask questions. Science is the perfect outlook for students to fully engage in their inquisitiveness, but yet, many classrooms are skipping over science lessons or choosing to heavily focus on other subjects, such as reading and writing. Science is often taught as an elective, integrated with other subjects or it is only focused on for a short period of time. Unfortunately, when this subject does receive attention, lessons are heavily text-book …

Study Of Alpha Mangostin As A Chemoprotective Agent For Breast Cancer Via Activation Of The P53 Pathway, Vanessa Van Oost

Honors Program Projects

Breast carcinoma is the most frequently diagnosed cancer among women and causes over 400,000 deaths each year worldwide. Current treatments such as chemotherapy are not selective for cancerous tissues but are destructive to normal tissues as well. This causes a range of side effects including pain, nausea, hair loss, weakness, and more. Inactivation of p53 is a very common mutation within human cancer cells. The ability to activate the p53 pathway which protects cells from tumor formation is lost in 50% of cancers. Due to the prevalence of this mutation, p53 is a uniquely valuable target for applied research. Alpha …

Pyy3-36 Efficacy Is Independent Of Photoperiod But Dependent On Time Of Day, Marissa Maroni

Honors Program Theses and Projects

Approximately 70% of Americans are overweight or obese and studies have shown that poverty-dense American counties are the most prone to obesity (Levine, 2011). Along with diet, the endogenous circadian rhythms have been found to be an important piece of human metabolic health. Circadian disruption in humans, such as jet-lag and shift work, have been linked to metabolic problems such as Type 2 Diabetes Mellitus and Metabolic Syndrome. Since circadian disruption affects many demographics including shift workers and routine business travelers it is imperative to understand the biological mechanism behind the relationship between circadian disruption and weight gain. One potential …

Zero Textbook Cost Syllabus For Env 3009/4900 (Conservation Biology And Sustainable Development), Stephen Gosnell

Open Educational Resources

Conservation biology is an interdisciplinary topic that explores how we can protect and maintain natural areas. Due to the resources we take and impacts we have on natural environments, this field is directly related to restoration ecology (restoring natural areas) and sustainable development/natural resource management. We will explore the basis for these related fields from an ecological, social, legal, and cultural perspective, as all conservation and management projects take place in the larger human landscape. We will consider how we measure biodiversity, why it matters, why is it is threatened, and how we can manage (protect, restore, maintain, use) it …
