Engaging People In Nature Stewardship Through Master Naturalist Programs, Mark Larese-Casanova, Michelle Prysby

Human–Wildlife Interactions

Master Naturalist programs across the country have reconnected Americans with nature for >20 years. Research suggests that reconnecting humans with nature benefits personal health and wellness, educates stakeholders about the importance of conservation, and enhances individual participation in stewardship efforts. Nationally, the Alliance of Natural Resource Outreach and Service Programs coordinates and supports Master Naturalist programs through facilitating collaboration and sharing of resources, as well as organizing an annual conference. We explore the Virginia Master Naturalist and Utah Master Naturalist programs as 2 examples of different, but highly effective, statewide programs to highlight the diversity of Master Naturalist programs. The …

Branch Mathematics and Statistics Faculty and Staff Publications

In this work, elements related to mental models elicitation and analysis are addressed through causal models. Issues related to the need to include indeterminacy in causal relationships through neutrophic cognitive maps are discussed. A proposal for static analysis in neutrosophic cognitive maps is presented. The following activities are included in the proposal: Calculate, measures of centrality, Classify nodes, De-neutrosification, and Ranking nodes. As future works, the incorporation of new metrics of centrality in neutrosophic cognitive maps is proposed. The inclusion of scenario analysis to the proposal is another area of future work.

Western Snowy Plover Nest Survival In Humboldt County, California, Katelyn M. Raby

Cal Poly Humboldt theses and projects

Productivity measures, such as nest survival, are often used to indirectly assess habitat quality and guide targeted management practices for the conservation of threatened and endangered species. The coastal population of the Western Snowy Plover (Charadrius nivosus nivosus) is listed as threatened due to three limiting factors: human disturbance, loss and degradation of habitat as a result of invasive plants, and increasing predator populations. I examined the relative influence of these three limiting factors on nest survival, using data from 2004 to 2017 at eight sites in Humboldt County, California. I assigned nests (n = 610) to three …

The Rhetoric Of Science Education And Technology, Iwasan D. Kejawa

School of Computing: Faculty Publications

Nearly thousands of science experiments are performed both on humans and animals every year in the United States (Gregory, 1999). Does Science enormously play a role in the well-beings of individual in the society? Research has found that science education is through motivation and satisfying the needs of humans. The scientific world is part of an elongated human development. This can be substantiated with the use and evolution of TECHNOLOGY and SCIENCE (Minton, 2004). Education of the entities that comprise the need to achieve the goal of TECHNOLOGY and SCIENCE which are important issues of today. Research has shown that …

Synthesis, Secretion, And Perception Of Abscisic Acid Regulates Stress Responses In Chlorella Sorokiniana, Maya Khasin, Rebecca E. Cahoon, Sophie Alvarez, Richard Beckeris, Seong-Il Eyun, Qidong Jia, Jean-Jack Riethoven, Kenneth Nickerson, Wayne R. Riekhof

Kenneth Nickerson Papers

Abscisic acid (ABA) is a phytohormone that has been extensively characterized in higher plants for its roles in seed and bud dormancy, leaf abscission, and stress responses. Genomic studies have identified orthologs for ABA-related genes throughout the Viridiplantae, including in unicellular algae; however, the role of ABA in algal physiology has not been characterized, and the existence of such a role has been a matter of dispute. In this study, we demonstrate that ABA is involved in regulating algal stress responses. Chlorella sorokiniana strain UTEX 1230 contains genes orthologous to those of higher plants which are essential for ABA …

Examination Of Methylation Sites For Forensic Age Determination From Semen, Christian Renwick, Sarah J. Seashols-Williams

UROP Posters

Methylation Sensitive High-Resolution Melt (MS-HRM) is based on quantitating the melt curve from an experimental sample against a standard of known methylation levels. Whereas most applications of age prediction using methylation markers are based upon pyrosequencing or SNaPshot technologies, these analysis methods are both cost and instrumentation prohibitive. This study sought to use to the varied methylation status of the ELOVL2 and FHL2 alleles, both having known correlation with age (Hamano et. al.), in a labor and time efficient manner to develop an age prediction model. A non-linear regression and standard curve was compiled from the methylation status in a …

On The Scattering Of Topographically Modified Semidiurnal Kelvin Waves Into Internal Waves, Tianyi Zhang

Theses and Dissertations

Semidiurnal tides propagate along continental shelves as a Kelvin wave mode. On wide continental shelves, the shelf topography modifies the Kelvin wave mode into a hybrid Kelvin-edge wave (HKEW), with features of a zero mode edge wave. Its free surface structure and alongshore energy flux concentrate on the shelf, and are sensitive to changes in the shelf width. When a propagating HKEW encounters an alongshore change of shelf width, the adjustment of wave structures results in the scattering of the incident wave into other wave modes, including barotropic and baroclinic Poincaré waves radiating offshore. These dynamics are studied using the …

Strike Hazard Posed By Columbids To Military Aircraft, Melanie R. Colón, Ashley M. Long

Human–Wildlife Interactions

Wildlife-aircraft strikes threaten both human and animal safety and result in hundreds of millions of dollars per year in aircraft damage and lost flight hours. Large-bodied birds are especially hazardous to aircraft. However, given high-speed flight at low altitudes, military aircraft may be especially vulnerable to strikes and more susceptible to damage even when encountering small birds. We summarized all wildlife-aircraft strike records from Randolph Air Force Base (San Antonio, Texas) over a 25-year period and compared the number and cost of strikes across avian species and species groups. Because columbids (i.e., pigeons and doves) are among the most frequently …

Motivations And Satisfaction Of North Dakota Deer Hunters During A Temporal Decline In Deer Populations, Kristen E. Black, William F. Jensen, Robert Newman, Jason R. Boulanger

Human–Wildlife Interactions

Achieving state wildlife agency biological goals for deer (Odocoileus spp.) management may often conflict with hunter desires. Concomitantly, better information is needed to optimize agency deer herd management goals with hunters’ social goals. In 2016, we surveyed 3,000 North Dakota, USA, resident deer hunters using a self-administered mail survey to gain a better understanding of motivations, satisfaction, and hunter demographics that may be used to inform hunter recruitment and retention (HRR) efforts during a period of reduced statewide deer populations. With deer-gun license availability strictly limited, we explored the possibility that some gun hunters may have been engaging …

Atomistic Simulations And Network-Based Modeling Of The Hsp90-Cdc37 Chaperone Binding With Cdk4 Client Protein: A Mechanism Of Chaperoning Kinase Clients By Exploiting Weak Spots Of Intrinsically Dynamic Kinase Domains, John Czemeres, Kurt Buse, Gennady M. Verkhivker

Mathematics, Physics, and Computer Science Faculty Articles and Research

A fundamental role of the Hsp90 and Cdc37 chaperones in mediating conformational development and activation of diverse protein kinase clients is essential in signal transduction. There has been increasing evidence that the Hsp90-Cdc37 system executes its chaperoning duties by recognizing conformational instability of kinase clients and modulating their folding landscapes. The recent cryo-electron microscopy structure of the Hsp90-Cdc37- Cdk4 kinase complex has provided a framework for dissecting regulatory principles underlying differentiation and recruitment of protein kinase clients to the chaperone machinery. In this work, we have combined atomistic simulations with protein stability and network-based rigidity decomposition analyses to characterize dynamic …

Virtual Reality As A Training Tool To Treat Physical Inactivity In Children, Adam W. Kiefer, David Pincus, Michael J. Richardson, Gregory D. Myer

Psychology Faculty Articles and Research

Lack of adequate physical activity in children is an epidemic that can result in obesity and other poor health outcomes across the lifespan. Physical activity interventions focused on motor skill competence continue to be developed, but some interventions, such as neuromuscular training (NMT), may be limited in how early they can be implemented due to dependence on the child’s level of cognitive and perceptual-motor development. Early implementation of motor-rich activities that support motor skill development in children is critical for the development of healthy levels of physical activity that carry through into adulthood. Virtual reality (VR) training may be beneficial …

Science And Sentiment: Affecting Change In Environmental Awareness, Attitudes, And Actions Through The Daily Nature Project, Elizabeth D. Haynes Poronsky

The Transdisciplinary STEAM+ Journal

Knowledge about what motivates pro-environmental behavior is important to organizations that seek to encourage environmental stewardship. Research suggests that targeting emotions and beliefs about nature can be more effective in changing environmental actions than increasing knowledge. Daily Nature, a site on the social media platform Facebook, features a daily nature photograph, a quote from a notable historical person and a related lyrical written passage. The popularity of this site lends credence to the appeal of interdisciplinary formats, and underscores the benefits of encouraging emotional and aesthetic ties to nature.

Evaluation Of A Direct Pcr Method And The Qiagen Investigator 24plex Go! Kit For Typing Blood, Saliva And Touch Dna On Multiple Substrates, Angelita Pierre-Noel

Student Theses

In forensic DNA typing, omitting the DNA extraction procedure and adding the sample directly to the polymerase chain reaction (direct PCR) mixture has several advantages. Without extraction and purification, there is less of a risk of sample loss, sample mix up, or contamination. This study tested the feasibility of direct PCR using the Qiagen® Investigator® 24plex GO! Kit, a megaplex kit that amplifies 22 polymorphic STR markers and the Amelogenin sex determination alleles. Test samples included blood, saliva and skin cells on porous substrates, specifically denim, white cotton, polyester fabric, and paper tissue. Glass slides were used to represent non-porous …

No Evidence For Trace Metal Limitation On Anaerobic Carbon Mineralization In Three Peatland Soils, Jason K. Keller, Jillian Wade

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Peatlands store roughly one-third of the terrestrial soil carbon and release the potent greenhouse gas methane (CH₄) to the atmosphere, making these wetlands among the most important ecosystems in the global carbon cycle. Despite their importance, the controls of anaerobic decomposition of organic matter to carbon dioxide (CO₂) and CH₄ within peatlands are not well understood. It is known, however, that the enzymes responsible for CH₄ production require cobalt, iron and nickel, and there is a growing appreciation for the potential role of trace metal limitation in anaerobic decomposition. To explore the possibility of …

Quantitative Pcr Assays For Detection Of Five Arctic Fish Species: Lota Lota, Cottus Cognatus, Salvelinus Alpinus, Salvelinus Malma, And Thymallus Arcticus From Environmental Dna, Torrey W. Rodgers, John R. Olson, Stephen L. Klobucar, Karen E. Mock

Ecology Center Publications

The North Slope of Alaska contains arctic fish populations that are important for subsistence of local human populations, and are under threat from natural resource extraction and climate change. We designed and evaluated four quantitative PCR assays for the detection of environmental DNA from five Alaskan fish species present on the North Slope of Alaska: burbot (Lota lota), arctic char (Salvelinus alpinus), Dolly Varden (Salvelinus malma), arctic grayling (Thymallus arcticus), and slimy sculpin (Cottus cognatus). All assays were designed and tested for species specificity and sensitivity, and all assays detected …

After The Flood: Fish Farming And Climate Change Adaptation In Chitwan, Nepal, Signe Stroming

Independent Study Project (ISP) Collection

Last summer, Nepal’s Terai region experienced some of the worst flooding in recent memory. Climate change is expected to increase the number of natural disasters that Nepal experiences in coming years, and more vulnerable demographics will be more adversely affected. Fish farming is a highly profitable and slowly growing industry based primarily in the Terai, that many believe is less vulnerable to climate-related risks than conventional forms of agriculture, and thus a possible livelihood adaptation strategy. In this study, I conducted semi-structured interviews with ten farmers in Madi, Chitwan, to understand the daily challenges and threats to fish farming, the …

Can Mine Reclamation With An Exotic Grass Species Precede Successful Restoration In Intermountain Grasslands? A Case Study With Agropyron Cristatum., Mark Mariano

Graduate Theses & Non-Theses

We performed four experiments to test whether or not native plants germinated with physical and chemical contact with crested wheatgrass (Agropyron cristatum (L.) Gaertn.), a grass species native to Eurasia which has been widely used for mine reclamation in North America. In our study area Butte, Montana, A. cristatum was planted on capped mine waste and, in many cases, has formed a monoculture with a large buildup of leaf litter. We found there to be a much higher mean litter depth on these lands when compared to wild grasslands. Leaf litter proved to be a significant barrier for the establishment …

Recognizing Challenges And Opportunities In The Quest To End Hunger, Jennifer Williams Zwagerman

Texas A&M Law Review

As an attorney and professor that does not focus on intellectual property law, I was a bit apprehensive about providing a keynote address for a Symposium focusing on “Agriculture, Intellectual Property, and Feeding the World in the 21st Century.” As I thought about this topic, knowing that there were other speakers who would focus more on the IP issues and technical aspects of various topics, I kept coming back to the importance of technology as we worktowards the goal of feeding the world, and the many ways in which innovation plays a role in meeting that goal. It also brought …

Department of Biology Faculty Scholarship and Creative Works

Grain weight is one of the most important yield components and a developmentally complex structure comprised of two major compartments (endosperm and pericarp) in maize (Zea mays L.), however, very little is known concerning the coordinated accumulation of the numerous proteins involved. Herein, we used isobaric tags for relative and absolute quantitation (iTRAQ)-based comparative proteomic method to analyze the characteristics of dynamic proteomics for endosperm and pericarp during grain development. Totally, 9539 proteins were identified for both components at four development stages, among which 1401 proteins were non-redundant, 232 proteins were specific in pericarp and 153 proteins were specific in …

T-Time: A Data Repository Of T Cell And Calcium Release-Activated Calcium Channel Activation Imagery, Cody Arbuckle, Milton L. Greenberg, Adrienne Bergh, Rene German, Nick Sirago, Erik J. Linstead

Mathematics, Physics, and Computer Science Faculty Articles and Research

BACKGROUND: A fundamental understanding of live-cell dynamics is necessary in order to advance scientific techniques and personalized medicine. For this understanding to be possible, image processing techniques, probes, tracking algorithms and many other methodologies must be improved. Currently there are no large open-source datasets containing live-cell imaging to act as a standard for the community. As a result, researchers cannot evaluate their methodologies on an independent benchmark or leverage such a dataset to formulate scientific questions.

FINDINGS: Here we present T-Time, the largest free and publicly available data set of T cell phase contrast imagery designed with the …

How Science Makes America Great, Kenneth Nickerson

Kenneth Nickerson Papers

The proposed Federal Budget cuts funding for NIH, NSF, and CDC by 16% each and for the EPA by a whopping 31%. Ouch! The situation seems ironic because of President Trump’s slogan “Make America great again!”, which I agree with wholeheartedly. In addition to being a scientist, I also love history (especially military history) and science is at the top of my list of what has made the United States great. ... Why do we do it? I’m in science because it is rewarding. It is invigorating to discover how nature works. Scientists may act individually and in relative obscurity, …

A Healthy Brain: Use It Or Lose It!, Elizabeth B. Fauth, Maria C. Norton

All Current Publications

Challenging your muscles makes for strong healthy muscles, and challenging your brain cells makes for a strong healthy brain. Build up your brain’s cognitive reserve – create a well-connected, high-capacity brain – through overall healthy behaviors (diet and exercise) and making mentally challenging activities part of your daily life. The more options your brain has to get its signals sent, the better able it is to handle areas of damage. A well-connected brain may be better able to delay or prevent diseases like Alzheimer’s.

Gosnell Studies And Communicates Ecological Concerns, Aldemaro Romero Jr.

Publications and Research

Scientists who study environmental problems know that the more you work in the field, the more insight you gain into how to solve problems. In other words, the more field experience you have, the deeper your understanding of nature.

One scientist who has had a lot of field experience is Dr. Stephen Gosnell, and his interest in the environment began when he was still a child. “I had interest really early. I grew up in rural South Carolina in a very small town called Landrum. I was outside on a regular basis, playing in the streams and creeks around me,” …

Beyond The Obvious: Emerging Contaminants And Biogeochemistry As A Cause And Solution For Nitrogen Pollution, Stephanie L. Devries

Dissertations, Theses, and Capstone Projects

Following a comprehensive review of the occurrence and impacts of antibiotics and related pharmaceutical compounds on the terrestrial N-cycle, three experiments were performed to explore the topic of biogeochemistry as a source or a sink for N-pollution. The first of these experiments addresses the question of whether environmentally relevant concentrations of antibiotics (µg·kg^-1) have a significant effect on denitrification or N₂O production, a question that has not been well addressed in previous studies. Having determined that there is a significant shift, the second study aims to comprehensively follow changes to soil N pools and N_{2 …}

Bioethics In The Work Of Ernest Everett Just: + Missing - Some 400 Pages, Theodore Walker

Perkins Faculty Research and Special Events

Biology + ethics = bioethics. Here we see that Howard University biologist Ernest Everett Just (born 1883, died 1941) connected biology to ethics.

According to Just, various forms of specific biology (including especially cell biology) plus “general biology” are necessary for explaining adequately the origin of ethical behaviors. Social ethical behaviors, especially mutual aid and cooperative interactions with others and the environment, are essential to evolutionary advances among living creatures, ranging from humans to cells. Accordingly, theory of ethics (moral theory) should have roots in biology.

Also, Just wrote an unpublished book-length manuscript—“some 400 typed pages” (Just 1940)—on seeking the …

Human-Nonhuman Chimeras, Ontology, And Dignity: A Constructivist Approach To The Ethics Of Conducting Research On Cross-Species Hybrids, Jonathan M. Vajda

The Hilltop Review

Developments in biological technology in the last few decades highlight the surprising and ever-expanding practical benefits of stem cells. With this progress, the possibility of combining human and nonhuman organisms is a reality, with ethical boundaries that are not readily obvious. These inter-species hybrids are of a larger class of biological entities called “chimeras.” As the concept of a human-nonhuman creature is conjured in our minds, either incredulous wonder or grotesque horror is likely to follow. This paper seeks to mitigate those worries and demotivate reasonable concerns raised against chimera research, all the while pressing current ethical positions toward their …
