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...

Chemistry and Grit: The Impact of Prerequisites vs Perseverance on Academic Success in Biology

Creator:: Sparks, Kiersten E.
Abstract:: Previous research on academic success in biology has focused on the influence of prerequisite knowledge and cognitive ability as measured by course grades or GPA. More recently, the field has considered the influence of non-cognitive factors such as grit, defined as passion and perseverance for long term goals. Both grit...

The Development and Application of a Systems Biology Approach to Mapping Monocyte Gene Regulatory Networks.

Creator:: Choudhury, Mudra
Abstract:: While monocytes are vital for host defense against pathogens, in cases of non-resolving inflammation, monocytes and their differentiated progeny can secrete tissue-damaging factors, present auto-antigens, and promote the inflammatory response. In this study, a systems biology approach was used to map human monocyte gene regulatory regions by integrating expression quantitative...

Diet analysis of Black Rockfish (Sebastes melanops) from stomach contents off the coast of Newport, Oregon

Creator:: Doran, Renee E.
Abstract:: Black Rockfish are important commercial and recreational species and understanding their biology is useful in developing best management practices. A common means to assess diet in both freshwater and marine fishes is stomach content analysis, which can determine diet composition and infer foraging behaviors. We conducted a stomach content analysis...

Adaptation to long-term osmotic stress in Saccharomyces cerevisiae

Creator:: Gosman, Andreea
Abstract:: An important goal of evolutionary biology is to identify the genetic mechanisms underlying phenotypes in organisms. Understanding adaptation to osmotic stress has many applications, since this stress affects almost all organisms on Earth. By studying the model organism Saccharomyces cerevisiae using experimental evolution, we can learn about genetic mechanisms driving...

Biological considerations for a new approach to regulating genetically modified crops in the United States

Creator:: McDonough, Ashley
Abstract:: The debate over GM crops is one of the most controversial issues of recent decades. The debate has many dimensions, including environmental impacts, benefits and risks to human health, intellectual property rights, adequacy of biosafety regulations, and fundamental ethical acceptability. The potential benefits of GM crops are numerous, including improved...

Antibiotic Discovery in Soil Bacteria Isolated from Indonesian Black Water Ecosystems

Creator:: Lam, Phillip Westly
Abstract:: Soil bacteria are known to be a prolific source of bioactive compounds. They produce secondary metabolites that can be used as therapeutic agents. This investigation focused on the chemistry and biology of secondary metabolites from two soil bacteria, Streptomyces herbaricolor ICBB 9409 and Streptomyces albiflaviniger ICBB 9297, which were isolated...

Investigating synergistic effects of climate and land-use change on the pollination of a tropical plant, Heliconia tortuosa

Creator:: Dowd, Claire E.
Abstract:: Loss of biodiversity due to the effects of climate and land-use change may have implications for pollination services. Disruption to phenological synchronicity or a reduction in the overlap in species distributions of plants and their pollinators may reduce floral resources to pollinators, forcing them to move farther distances. If pollinators...
