Factors Influencing Primate Hair Microbiome Diversity, Catherine Kitrinos 2021 University of Massachusetts Amherst

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 …

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 2021 Children's Hospital Boston

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 …

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 2021 Miami University

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 2021 The Graduate Center, City University of New York

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 …


Sickness Behaviors Across Vertebrate Taxa: Proximate And Ultimate Mechanisms, Patricia C. Lopes, Susannah S. French, Douglas C. Woodhams, Sandra A. Binning 2021 Chapman University

Sickness Behaviors Across Vertebrate Taxa: Proximate And Ultimate Mechanisms, Patricia C. Lopes, Susannah S. French, Douglas C. Woodhams, Sandra A. Binning

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

There is nothing like a pandemic to get the world thinking about how infectious diseases affect individual behavior. In this respect, sick animals can behave in ways that are dramatically different from healthy animals: altered social interactions and changes to patterns of eating and drinking are all hallmarks of sickness. As a result, behavioral changes associated with inflammatory responses (i.e. sickness behaviors) have important implications for disease spread by affecting contacts with others and with common resources, including water and/or sleeping sites. In this Review, we summarize the behavioral modifications, including changes to thermoregulatory behaviors, known to occur in vertebrates …

Constraining The Atmospheric Limb Of The Plastic Cycle, Janice Brahney, Natalie Mahowald, Marje Prank, Gavin Cornwell, Zbigniew Kilmont, Hitoshi Matsui, Kimberly Ann Prather

Watershed Sciences Faculty Publications

Plastic pollution is one of the most pressing environmental and social issues of the 21st century. Recent work has highlighted the atmosphere’s role in transporting microplastics to remote locations [S. Allen et al., Nat. Geosci. 12, 339 (2019) and J. Brahney, M. Hallerud, E. Heim, M. Hahnenberger, S. Sukumaran, Science 368, 1257–1260 (2020)]. Here, we use in situ observations of microplastic deposition combined with an atmospheric transport model and optimal estimation techniques to test hypotheses of the most likely sources of atmospheric plastic. Results suggest that atmospheric microplastics in the western United States are primarily derived from secondary re-emission …

Killing The Planet But Saving The People: How The American Healthcare Industry Impacts The Environment, Malorie Webb

Senior Theses

The American population is rapidly growing and aging. In order to accommodate such a large population and its associated challenges, the healthcare industry has had to continually expand and adapt. The United States healthcare industry is now one of the largest, most expensive components of the economy. As such, it produces vast amounts of waste. Healthcare waste can damage the environment and contribute to climate change, which in turn can contribute to worsening health outcomes in the population. This thesis aims to explore both the immediate and prolonged impacts of the American healthcare industry on the environment, as well as …


A Dynamic Energy Budget Model Of Ornate Box Turtle Shell Growth, Tyler Skorczewski, Brandon Andersen 2021 University of Wisconsin-Stout

A Dynamic Energy Budget Model Of Ornate Box Turtle Shell Growth, Tyler Skorczewski, Brandon Andersen

Spora: A Journal of Biomathematics

Many aspects of box turtle development may depend on size rather than age. Notable examples include sexual maturity and the development of the fully closing hinge in the shell that allows box turtles to completely hide in their shells. Thus, it is important to understand how turtles grow in order to have a complete understanding of turtle biology. Previous studies show that turtle shell growth behaves in a logistic manner. These studies use functional models that fit the data well but do little to explain mechanisms. In this work we use the ideas found in dynamic energy budget theory to …


Exploring Factors In Choosing Stem Majors And Careers: Improving Science Education Through The Lens Of Self-Determination Theory, Lauren Mott 2021 University of Nebraska - Lincoln

Exploring Factors In Choosing Stem Majors And Careers: Improving Science Education Through The Lens Of Self-Determination Theory, Lauren Mott

Honors Theses, University of Nebraska-Lincoln

Several barriers currently exist for students who could be successful in science/STEM careers but have not had the support they needed throughout their science/STEM education. This study of the literature applies Self-Determination Theory (SDT) to existing research to identify steps educators can take to remove these unnecessary barriers for their students. SDT defines competence, relatedness, and autonomy as three innate psychological needs that must be met for well-being. An exploratory review of the literature was conducted, and findings were organized using SDT. The results showed that competence, relatedness, and autonomy were all key factors in students’ self-determination of science/STEM careers. …

Functional Influence Of 14-3-3 (Ywha) Proteins In Mammals, Elizabeth Barley, Santanu De 2021 Nova Southeastern University

Functional Influence Of 14-3-3 (Ywha) Proteins In Mammals, Elizabeth Barley, Santanu De

Mako: NSU Undergraduate Student Journal

The 14-3-3 (YWHA) proteins are homologous, ubiquitous, and conserved in most organisms ranging from plants to animals and play important roles in regulating key cellular events such as cell signaling, development, apoptosis, etc. These proteins consist of seven isoforms in mammals, termed under Greek alphabetization: beta (β), gamma (γ), epsilon (ε), eta (η), tau/theta (τ), sigma (σ), and zeta (ζ). Each of these isoforms can interact with a plethora of binding partners and has been shown to serve a distinct role in molecular crosstalk, biological processes, and disease susceptibility. Protein 14-3-3 isoforms are scaffolding proteins capable of forming homodimers and …
