Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Led by His Holiness the Dalai Lama, the initiative taken by the Tibetan Buddhist monastic community to connect with western science and scientists presents a unique opportunity to understand the motivations and engagement behaviors that contribute to monastic science learning. In this study, we draw on quantitative data from two distinct surveys that track motivations and engagement behaviors related to science education among monastic students. The first survey was administered at one monastic university in 2018, and the second follow-up survey was completed by students at two monastic universities in 2019. These surveys assessed the reception of science education related …

Population Dynamics, Relative Abundance, And Habitat Suitability Of Adult Red Drum (Sciaenops Ocellatus) In Nearshore Waters Of The North-Central Gulf Of Mexico, Crystal Hightower, J. Marcus Drymon, Amanda E. Jefferson, Matthew B. Jargowsky, Emily A. Seubert, Simon Dedman, John Mareska, Sean P. Powers

University Faculty and Staff Publications

In the Gulf of Mexico, the red drum (Sciaenops ocellatus) is an immensely popular sportfish, yet the Gulf of Mexico stock is currently managed as data-limited in federal waters. The results of the federal stock assessment conducted in 2016 for Gulf of Mexico red drum were not recommended for providing management advice. Consequently, we sought to address data gaps highlighted in the assessment by producing up-to- date overall and sex-specific growth models, standardized indices of relative abundance, and predictions of habitat suitability and by updating estimates of natural mortality. Using a time series for the period of 2006–2018, we assigned …

Fish And Invertebrate Use Of Restored Vs. Natural Oyster Reefs In A Shallow Temperate Latitude Estuary, Jonathan H. Grabowski, Christopher J. Baillie, Adam Baukus, Rachael Carlyle, F. Joel Fodrie, Rachel K. Gittman, A. Randall Hughes, David L. Kimbro, Juhyung Lee, Hunter S. Lenihan, Sean P. Powers, Kevin Sullivan

Coastal marine habitats continue to be degraded, thereby compelling largescale restoration in many parts of the world. Whether restored habitats function similarly to natural habitats and fully recover lost ecosystem services is unclear. In estuaries, oyster reefs have been degraded by multiple anthropogenic activities including destructive fishing practices and reduced water quality, motivating restoration to maintain oyster fisheries and other ecosystem services, often at relatively high cost. We compared fish and invertebrate communities on recently restored (0–1 year post-restoration), older restored (3–4 years post-restoration), and natural oyster reefs to determine if and when restored reefs support functionally similar faunal communities. …

Responses Of Arthropods To Fire And How Pollinators And Pollination Services Are Affected By Fire Severity, Blyssalyn V. Bieber

Electronic Theses and Dissertations

Fires impact ecosystems globally and due to climate change, there are shifts in fire regimes that impact ecological communities which provide essential ecosystem services. Focusing on arthropods, fire can influence this ubiquitous animal group in various way. We performed a comprehensive meta-analysis evaluating how fires impact differing arthropod functional groups. We found that overall, fire negatively effects community level responses for most functional groups with herbivores as the only exception showing some positive effects of fire. We also studied mixed-severity fires that burned >20 years ago and compared floral visitor communities across fire severities. We implemented a pollinator exclusion experiment …

Chronic Adolescent Stress As A Predictive Factor For The Risk Of Developing Ptsd-Like Symptoms In Adulthood, Grace K. Young

Theses and Dissertations

Post-traumatic stress disorder is a stress and trauma based psychological disorder that is defined by the DSM-IV as an anxiety disorder that affects approximately 7.8% of people in the United States. PTSD is when those who suffer a traumatic event have intense and distressing feelings, emotions, and memories for a prolonged period of time after the event. A prominent feature of PTSD is the impaired ability to properly extinguish a fear response after a dangerous trigger or stressor is no longer present, also known as safety learning. Stressors are threats perceived within the environment that activate a response within the …

Human–Carnivore Conflicts In A Recently Established Pakistani National Park, Rukhsana Khatoon, Maqsood Anwar, Charles H. Nilon, Matthew E. Gompper

Human–Wildlife Interactions

Human–carnivore conflicts (HCCs) are increasing globally. These conflicts may encompass competition for food resources, crop and livestock depredations, and attacks on humans. Concerns over conflicts may result in retaliatory killings of carnivores and negative views of wildlife or landscape conservation. Yet, despite the economic and conservation implications of HCCs, data regarding the magnitude and severity of the conflicts may be lacking because many incidents are unreported. To better inform this issue, we compared HCC data for 2016 to 2018 obtained from official records of the Punjab Wildlife and Parks Department for a newly established national park in the Punjab Region …

Public Perceptions Of Human Physical Interactions, Exhibition, And Conservation Of Tigers And Cheetahs, Abbie Knudsen

MSU Graduate Theses

Tigers and cheetahs are common in the pet trade, public exhibits, and hands-on encounters with the public. Poor regulation of these experiences has resulted in numerous incidents worldwide in which a person was seriously injured or killed by captive big cats. Additionally, concerns for animal welfare have been raised by industry professionals. Prior research on primates has demonstrated exposing people to photographs of cats in different backgrounds can influence their attitudes about animals in captivity, but no study has addressed whether visual images affect human attitudes toward big cats. I used a survey that asked a series of questions about …

Application Of Competitive Intelligence For Insular Territories: Automatic Analysis Of Scientific And Technology Trends To Fight The Negative Effects Of Climate Change, Henri Dou, Pierre Fournie

International Journal of Islands Research

Islands are fragile territories because of their geographical position. As a result, climate impacts can have serious consequences, of which some are irreversible. Therefore, it is necessary to allow insular territories to benefit from the latest scientific and technological advances in combating climate effects. The current article shows how to deal with automatic analysis of scientific information on the one hand, but also its applications via patents. We will analyse the latest scientific results as well as their possible applications using patent analysis. We will also focus on experts, laboratories, and leading companies, that are active on the field. The …

Farnesol Secretion As A Possible Driving Force For Maintaining Candida Albicans As A Diploid, Kenneth Nickerson, Cory Boone, Kory Parker

Kenneth Nickerson Papers

Candida albicans is a pathogenic dimorphic fungus which is invariably found as a diploid in patients. C. albicans secretes the sesquiterpene farnesol both as a quorum sensing molecule which blocks the yeast to hypha conversion and as a virulence factor for pathogenicity. 20-25 μM farnesol kills other competing yeasts and fungi, often by triggering apoptosis, and yet wild type diploid C. albicans tolerates 300-500 μM farnesol. The recent availability of 10 haploid strains of C. albicans (5 mating type aand 5 mating type α) allowed us to compare their production of and sensitivity to farnesol. On average, the heterozygous diploid …

Applying Artificial Intelligence In The Hotel Industry: Exploring Perspectives Of Employees, Logan O'Hara

Human Nutrition and Hospitality Management Undergraduate Honors Theses

Robots, Artificial Intelligence, and Service Automation, or RAISA, has become increasingly accessible and affordable for a wider demographic of businesses, including hospitality operations, to implement over the last couple of decades. Especially over the past five years, we’ve seen a significant surge of interest in automating within the service industry and a coupled sense of uneasiness that this technological development would in turn displace the human workers, due to factors such as cost of labor and perceived removal of human error; however, this thesis will posit that automation is most effectively used by augmenting the capabilities of the present workforce. …

La migración internacional tiene consecuencias económicas y en la salud. El proceso de aculturación en el país de acogida puede estar relacionado con la obesidad infan-til. Utilizamos el marco conceptual del balance energético comunitario (CEB, por sus siglas en inglés) para analizar la relación entre migración y obesidad infantil en los hogares mexicanos con migrantes internacionales. Utilizando datos longitudinales de la Encuesta Nacional de Niveles de Vida de los Hogares de México (ENNViH), exami-namos cómo influyen las redes de migrantes sobre la obesidad infantil en las comuni-dades de origen. También revisamos programas de salud binacionales que podrían ser eficaces para …

Factors Influencing Primate Hair Microbiome Diversity, Catherine Kitrinos

Masters Theses

Primate hair is both a substrate upon which essential social interactions occur and an important host-pathogen interface. As commensal microbes provide important immune functions for their hosts, understanding the microbial diversity in primate hair could provide insight into primate immunity and disease transmission. While studies of human hair and skin microbiomes show differences in microbial communities across body regions, little is known about the nonhuman primate hair microbiome. In this study, we collected hair samples (n=159) from 8 body regions across 12 nonhuman primate species housed at 3 US institutions to examine 1) the diversity and composition of the primate …

Hunter Motivations And Use Of Wild Pigs In Texas, Usa, Rachael L. Connally, Maureen G. Frank, Gary E. Briers, Nova J. Silvy, Keith M. Carlisle, John M. Tomeček

Human–Wildlife Interactions

Wild pigs (Sus scrofa) are a widespread exotic, invasive species that pose ecological, agricultural, and human health risks in their invaded range. Wildlife managers must manage wild pig abundance and range expansion to mitigate these risks. The diversity of stakeholders involved in the issue of wild pig management complicates efforts to manage the species, and, to be successful, wildlife professionals must consider the human dimensions associated with wild pig management. The prevalence of privately owned lands in Texas, USA necessitates cooperation to enact effective management policies. In this study, we investigate the impact of hunter motivations on wild …

Sterol Biosynthesis In Four Green Algae: A Bioinformatic Analysis Of The Ergosterol Versus Phytosterol Decision Point, Adam Voshall, Nakeirah T.M. Christie, Suzanne L. Rose, Maya Khasin, James L. Van Etten, Jennifer E. Markham, Wayne Riekhof, Kenneth Nickerson

Kenneth Nickerson Papers

Animals and fungi produce cholesterol and ergosterol, respectively, while plants produce the phytosterols stigmasterol, campesterol, and β-sitosterol in various combinations. The recent sequencing of many algal genomes allows the detailed reconstruction of the sterol metabolic pathways. Here, we characterized sterol synthesis in two sequenced Chlorella spp., the free-living C. sorokiniana, and symbiotic C. variabilis NC64A. Chlamydomonas reinhardtii was included as an internal control and Coccomyxa subellipsoidea as a plant-like outlier. We found that ergosterol was the major sterol produced by Chlorella spp. and C. reinhardtii, while C. subellipsoidea produced the three phytosterols found in plants. In silico analysis of the …

Anatomy And Physiology Preparatory Course Textbook (2nd Edition), Carlos Liachovitzky

Open Educational Resources

The goal of this preparatory textbook is to give students a chance to become familiar with some terms and some basic concepts they will find later on in the Anatomy and Physiology course, especially during the first few weeks of the course.

Organization and functioning of the human organism are generally presented starting from the simplest building blocks, and then moving into levels of increasing complexity. This textbook follows the same presentation. It begins introducing the concept of homeostasis, then covers the chemical level, and later on a basic introduction to cellular level, organ level, and organ system level. This …

Characteristics Of Non-Fatal Attacks By Black Bears: Conterminous United States, 2000–2017, Janel M. Scharhag, Cady Sartini, Shawn M. Crimmins, Scott E. Hygnstrom, Jeffrey B. Stetz

Human–Wildlife Interactions

Attacks on humans by bears (Ursus spp.) have increased in recent decades, as both human and bear populations have increased. To help mitigate the risk of future attacks, it is important to understand the circumstances in past attacks. Information and analyses exist regarding fatal attacks by both American black bears (Ursus americanus) and brown bears (U. arctos) as well as non-fatal attacks by brown bears. No similarly thorough analyses on non-fatal attacks by black bears are available. Our study addressed this information gap by analyzing all (n = 210) agency-confirmed, non-fatal attacks by black …

Conclusion: Female Leaders Using Coercive Power Motivate Subordinates, Mary Kovach

The Journal of Values-Based Leadership

This manuscript advances prior research (Blau, 1964; Elangovan & Xie, 1999; French & Raven, 1959; Goodstadt & Hjelle, 1973; Hegtvedt, 1988; Randolph & Kemery, 2011; Zigarmi, Peyton Roberts, & Randolph, 2015) and capitalizes on supervisory skills using power dynamics within the workplace, by investigating employee effort resulting from gender dissimilar supervisor-employee dyads and employee locus of control. To offer a more focused approach, this is an evaluation specifically on reward and coercive power derived from French and Raven’s (1959) five power bases. This manuscript proposes that the motivation levels of employees change, based on their locus of control and gender. …

Water-Responsive, Peptide-Based Crystals, Roxana Piotrowska

Dissertations, Theses, and Capstone Projects

Water-responsive (WR) materials  that exert significant forces in response to changing hydration levels are receiving growing interest due to their potential applications, including use as actuators for energy harvesting devices, artificial muscles, and soft robotics. Reported examples include biological and synthetic materials with abilities to efficiently convert the chemical potential of water into mechanical actuations. However, these systems are typically complex, and consequently, their WR mechanisms are not well-understood thus preventing rational design and optimization. This thesis demonstrates the design and development of WR peptide crystals that mimic and enhance understanding of natural WR systems. The peptide crystals, with intrinsic …
