The Mathematics of Critical Shifts in Ecological Networks with Alternative Stable State Theory, A Potential Framework for Early Warning Indicators

Creator:: Kupperman, Michael D.
Abstract:: A long running problem in mathematical biology is the prediction of extinction events, a specialized case of the larger global stability problem found in differential equations and dynamical systems theory. A central technical question is how to introduce the randomness observed in real ecological systems not accounted for in deterministic...

Localized Structures in a Diffusive Run-and-Tumble Model of Myxococcus xanthus

Creator:: Flynn, Patrick Thomas
Abstract:: The bacteria Myxococcus xanthus clusters into fruiting bodies in the absence of food. The movement of M. xanthus has three aspects: self-propulsion (run), change of direction due to collision (tumble), and Brownian fluctuations in movement. We propose a minimalist PDE model for the concentrations of left and right moving agents...

Introduction of a Mathematical Model to Characterize Relative Risk of Snakebite Envenoming, a Neglected Tropical Disease

Creator:: Kim, Soyeon
Abstract:: Snakebite envenoming is a neglected tropical disease that has received increased research attention in the past few years. However, snakebite prevalence and impact in India has been a neglected area of study, despite the high disease burden in this region. Both qualitative and quantitative approaches to studying snakebite processes are...

Mathematical Investigation of Evaporation Synergy in Bi-Texture Soil Columns as a Function of Column Width

Creator:: Sumner, Michael J.
Abstract:: Evaporation synergy is a phenomenon that occurs between different classes of soil and allows for a greater amount/quantity of soil water evaporation. 20 of the 66 soil texture class combinations have been shown to exhibit evaporation synergy (Fisher, 2012), however the impact of column width on the functionality of this...

Initial Mathematical Competency as a Determinant of Student Success in Algebra-Based Physics Courses

Creator:: Guske, Christopher
Abstract:: There has been a growing focus within the physics education field on researching the determinants to student success in college physics. Numerous investigations have examined the relationship between initial mathematical competency and student performance in college physics and have found considerable positive correlations. We contribute to this existing research on...

Development of assessment to determine first term general chemistry mathematical fluency

Creator:: Tomlinson, Kiara A.
Abstract:: The purpose of this study was to analyze the scores of a mental math quiz taken by the CH 231 trailer course at Oregon State University and to determine courses of action to increase the success of students in general chemistry based on the results of the analysis. Students were...

The Biogeography of European Bats

Creator:: Olson Dougan, Jackson Martin
Abstract:: Understanding species distributions temporally and spatially will facilitate effective conservation efforts and catalyze informed environmental management decisions. The predicted distributions of 31 species of European bat (Mammalia: Chiroptera) were mapped across Europe using species presence records and environmental data from 72 environmental variables (annual mean temperature, precipitation, etc.). In order...

Population structure and genetic variation in the Hawaiian Opakapaka (Pristipomoides filamentosus): Evidence of a genetic bottleneck in offspring of a captive broodstock

Creator:: Meltvedt, Ariana
Abstract:: The Hawaiian Archipelago is a biologically diverse environment with dynamic interactions between human and biological populations. Political, social, and scientific communities are placing importance on sustainable management of fisheries resources throughout the islands. Many economically important bottomfish in Hawaii have declined in population size due to anthropogenic and environmental pressures....

The Predictability of Qualitative Food Web Dynamics in Response to Extinction and Invasion

Creator:: Rockow, David J.
Abstract:: Food webs are extraordinarily complex, containing myriad direct interactions and indirect effects. Determining how this network of interactions and effects influences a food web’s qualitative dynamics is a challenging task, especially because data on food web structure and individual interaction strengths is unknown in virtually all real-world ecosystems. The goal...

Creation of an Initial Course and Curriculum Overview for a Positive Youth Development Certificate

Creator:: Pugh, Kiley M.
Abstract:: Positive Youth Development (PYD) is both a set of outcomes and a program model that serves to support youth in building healthy relationships with adults and developing the strengths necessary for healthy adulthood. It centers around the 5 C’s of compassion, character, competence, confidence, and connection, which lead to a...
