The Effect Of Agkistrodon Contortrix And Crotalus Horridus Venom Toxicity On Strike Locations With Live Prey, Chase Giese Jan 2021

The Effect Of Agkistrodon Contortrix And Crotalus Horridus Venom Toxicity On Strike Locations With Live Prey, Chase Giese

Department of Environmental Studies: Undergraduate Student Theses

This paper aims to uncover if there is a significant difference in the strike location of snake species that have different values of LD50% venom. It is thought that most snakes strike their prey in the anterior (head) area in order for their venom to work quicker in killing them. Venom toxicity is measured by its LD50% value, which is the amount of venom, in mg/kg, to kill 50% of a test population. The Copperhead has an LD50% value of 10.9 mg/kg, and the Timber Rattlesnake has an LD50% value of 1.64 mg/kg. The hypothesis was that if venom toxicity …

Regenerative Agriculture’S Potential Carbon Storage In Nebraska Soils, Jenna Mccoy Jan 2021

Regenerative Agriculture’S Potential Carbon Storage In Nebraska Soils, Jenna Mccoy

Department of Environmental Studies: Undergraduate Student Theses

This meta-analysis investigates the possible carbon sequestration of no-till and cover crop practices on Nebraska farmlands. These management practices are part of regenerative agriculture, a farming method designed to mitigate and adapt to climate change. As climate change is expected to significantly reduce yields in Nebraska, sequestering carbon in farmlands offers a way to adapt to climate change impacts and lower the concentration of carbon dioxide in the atmosphere. However, changing management practices is difficult and is driven primarily by economics. This study aims to determine how much carbon these practices can sequester in Nebraska soil each year by evaluating …

Prehistoric Human Tracks In Ojo Guareña Cave System (Burgos, Spain): The Sala And Galerías De Las Huellas, Ana I. Ortega, Francisco Ruiz, Miguel A. Martín, Alfonso Benito-Calvo, Marco Vidal, Lucía Bermejo, Theodoros Karampaglidis

KIP Articles

In 1969, members of Grupo Espeleológico Edelweiss discovered the Sala and Galerías de las Huellas in Ojo Guareña Cave system (Burgos, Spain). These contained hundreds of ancient human footprints, preserved in the soft sediment on the floor. These footprints represent the tracks of a small group of people who walked barefoot through these complex passages in the cave. Owing to the difficult compatibility of the documentation and preservation of these prints, it was not possible to study them before the development of new non-invasive remote sensing techniques. However, since 2012 optical laser scanning and digital photogrammetry have been used in …

Responses Of Predatory Myxobacteria To Prey Signaling Molecules & Features Of A Pseudomonas Prey Avoiding Predation, Shukria Akbar Jan 2021

Responses Of Predatory Myxobacteria To Prey Signaling Molecules & Features Of A Pseudomonas Prey Avoiding Predation, Shukria Akbar

Electronic Theses and Dissertations

Gram-negative unicellular myxobacteria, along with their multicellular lifestyle andbiologically active specialized metabolites, are known for the predatory interactions with Gram-negative/ Gram-positive bacteria and fungi. Although myxobacterial predation range have been exploited extensively, little is known about the prey associated molecules contributing to myxobacterial predator-prey dynamics. By employing transcriptomics and untargeted metabolomics approaches, we demonstrate two structurally distinct classes of signaling molecules from Gram-negative bacterial prey elicit significant omics responses from myxobacteria, Myxococcus xanthus and Cystobacter ferrugineus. An overlapping and general response to acylhomoserine lactones, whereas a distinctive response to a quinolone signaling molecule is observed from both myxobacteria. Similarly, by …

Quantifying Microbial Resistance To Nematode Predation, Tyler Bacon Jan 2021

Quantifying Microbial Resistance To Nematode Predation, Tyler Bacon

Electronic Theses and Dissertations

The selection pressure of predation has encouraged the development of defense traits that can make an individual species more environmentally stable. In addition to biotic pressures, abiotic factors could lead to disruption of predator-prey balance within ecosystems. Consequently, it is significant to better understand how environmental factors can influence predator-prey interactions and how responses may, in turn, affect communities. A current challenge within microbial communities is to understand which intraspecific traits associated with such defense strategies are important for microbial-prey responses to predation, and how the responses vary across environments revealing GxE interactions. In this study, I examined microbial-predator prey …

Survival And Sovereignty : Forces On The Rise In Aurelio Tolentino’S Novels, Loida L. Garcia Jan 2021

Survival And Sovereignty : Forces On The Rise In Aurelio Tolentino’S Novels, Loida L. Garcia

Manusya, Journal of Humanities

Aurelio Tolentino (1869–1915) is best remembered as the first nationalist dramatist who was in and out of prison because of his mutinous writings. His five extant novels manifest the sociopolitical struggle of early 20th-century Filipinos from the worldview of a versatile author. Tolentino’s fiction from 1909 to 1914 unveils how the colonized adapted ingrained, rigid, and conventional Spanish influences to the liberal and materialistic scheme imposed by the United States. A sociohistorical approach was used to investigate Tolentino’s narratives, revealing a people with a pliant but firm character brought about by their four centuries of subjugation. The literary method used …

Association For Molecular Pathology V. Myriad Genetics: A Critical Reassessment, Jorge L. Contreras Jan 2021

Association For Molecular Pathology V. Myriad Genetics: A Critical Reassessment, Jorge L. Contreras

Michigan Technology Law Review

The Supreme Court’s 2013 decision in Association for Molecular Pathology v. Myriad Genetics is an essential piece of the Court’s recent quartet of patent eligibility decisions, which also includes Bilski v. Kappos, Mayo v. Prometheus, and Alice v. CLS Bank. Each of these decisions has significantly shaped the contours of patent eligibility under Section 101 of the Patent Act in ways that have been both applauded and criticized. The Myriad case, however, was significant beyond its impact on Section 101 jurisprudence. It was seen, and litigated, as a case impacting patient rights, access to healthcare, scientific freedom, …

A Lexical Approach To Collective Personality Using Nongroup Members As Raters, Robert Cameron Black Jan 2021

A Lexical Approach To Collective Personality Using Nongroup Members As Raters, Robert Cameron Black

Walden Dissertations and Doctoral Studies

The construct of personality exhibits utility in predicting group outcomes. However, quantifying a group personality construct has almost exclusively been accomplished by aggregating individual group member five-factor personality scores to derive the group personality score. This type of operationalizing rests on the assumption that collective personality exists and has a five-factor structure, makes results context specific, and limits cross-comparison of different types of groups. The purpose of this quantitative study was to apply a lexical approach and exploratory factor analysis to explore personality structure of a group at a group level. The research question focused on identifying if a construct …

Responses Of Myxobacteria To Plant-Related Chemosignals Suggests Their Roles In The Rhizobiome, Barbara Iyare Adaikpoh Jan 2021

Responses Of Myxobacteria To Plant-Related Chemosignals Suggests Their Roles In The Rhizobiome, Barbara Iyare Adaikpoh

Electronic Theses and Dissertations

In the rhizosphere, plants curate and maintain distinct rhizobiome, some of which serve as secondary defense mechanisms against pathogenic microorganisms. Additionally, in response to biotic stress, plants generate phytohormones which regulate signaling pathways to activate systemic resistance. These phytohormones contribute to the chemical space within the rhizosphere in addition to other low-molecular-weight metabolites used for cell-to-cell communication within species and across kingdoms. However, little is known about the influences of stress-related phytohormones on beneficial bacteria even though biocontrol strategies abundantly explore plant-beneficial microorganisms to manage pathogens in agricultural systems. Myxobacteria are competent predators of plant pathogens and have demonstrated responses …

Comparative Study Of Agrogeophysical Methods For Identifying Soil Pipes, Md Abdus Abdus Samad Jan 2021

Comparative Study Of Agrogeophysical Methods For Identifying Soil Pipes, Md Abdus Abdus Samad

Electronic Theses and Dissertations

Soil erosion is considered the greatest challenge for soil management and agri-food production threatening human habitat and livelihood. Although soil erosion due to surficial processes has been well studied, the role of the subsurface process such as internal soil pipes has often been overlooked. Internal soil pipes directly contribute to total soil loss in agricultural fields that severely threaten agricultural sustainability. Locating, measuring, and mapping internal soil pipes and their networks are vital to assess the total soil loss in agricultural fields. Internal soil pipes are not commonly visible at the surface, and their subsurface networks rarely follow the surface …

Modeling Rna:Dna Hybrids With Formal Grammars, Natas̆A Jonoska, Nida Obatake, Svetlana Poznanović, Candice Price, Manda Riehl, Mariel Vazquez

Mathematics Sciences: Faculty Publications

R-loops are nucleic acid structures consisting of a DNA:RNA hybrid and a DNA single strand. They form naturally during transcription when the nascent RNA hybridizes to the template DNA, forcing the coding DNA strand to wrap around the RNA:DNA duplex. Although formation of R-loops can have deleterious effects on genome integrity, there is evidence of their role as potential regulators of gene expression and DNA repair. Here we initiate an abstract model based on formal grammars to describe RNA:DNA interactions and the formation of R-loops. Separately we use a sliding window approach that accounts for properties of the DNA nucleotide …
