Phenotypic Plasticity In A Stochastic Environment: Modeling Three Phenotypes And Environments, Sarah P. Williams, Marissa C. K. Douglas, Stephen C. Adolph May 2026

Phenotypic Plasticity In A Stochastic Environment: Modeling Three Phenotypes And Environments, Sarah P. Williams, Marissa C. K. Douglas, Stephen C. Adolph

Spora: A Journal of Biomathematics

Phenotypically plastic organisms are capable of adjusting their phenotypes in a variable environment. Padilla and Adolph (1996) modeled this process and included a time lag between detection of an environmental change and the responding change in phenotype. We extended the Padilla and Adolph model from two to three discrete environments and phenotypes and analyzed the model computationally. Our results were consistent with their findings: the fitness advantage of phenotypic plasticity is higher when (1) the lag time is shorter, (2) the probability of environmental change is lower, and (3) the fitness disadvantage of mismatched phenotypes and environments is more severe. …


Managing Multi-Drug Resistance: An Evolutionary Game Theory And Optimal Control Approach, Shukhrat Nasrulloev Jan 2026

Managing Multi-Drug Resistance: An Evolutionary Game Theory And Optimal Control Approach, Shukhrat Nasrulloev

Theses and Dissertations

Multi-drug resistance is an evolutionary process in which treatment eliminates sensitive cells, allowing resistant clones to dominate. This thesis investigates this process using a framework integrating population dynamics, evolutionary game theory, and optimal control theory. We develop a two-population logistic growth model describing competition between drug-sensitive and drug-resistant cells under treatment, construct dose-dependent payoff matrices and replicator dynamics to characterize evolutionary competition, and derive a critical drug level Dcrit = (rS - rR)/(dS - dR) at which resistant cells gain a fitness advantage. An optimal control problem is formulated via Pontryagin's Maximum Principle to identify schedules …


Interactive Effects Of Bti Larviciding And Predation On Culex Pipiens And Its Ephemeral Pond Communities, Jaclyn S. Everly Jan 2026

Interactive Effects Of Bti Larviciding And Predation On Culex Pipiens And Its Ephemeral Pond Communities, Jaclyn S. Everly

Theses and Dissertations

Populations of adult vector mosquitoes can be controlled by reducing larval mosquito abundances in aquatic habitats. This can be achieved via predation by introduced or naturally-occurring enemies (i.e., biocontrol or conservation control) or by applying pesticides to larval mosquito habitats (i.e., larviciding). The larvicide Bacillus thuringiensis israelensis (Bti) is commonly applied to ephemeral ponds to control populations of Culex pipiens mosquitoes that vector West Nile virus. However, there is concern that Bti may directly or indirectly harm non-target organisms such as dragonfly and damselfly naiads, which provide a natural source of mosquito biocontrol. Bti or predators may also induce positive …

On Solving Differential Equations Describing The Ecology Of Shallow Lakes: A Comparison Of Classical And Modern Computational Methods Through Python, Vruddhi Kapre, Jeffrey R. Anderson, Alessandro Maria Selvitella

Spora: A Journal of Biomathematics

In this exposition paper, we describe some computational methodologies to solve numerically differential equations modeling the shallow lake ecosystem, with particular focus on the dynamics of the phosphorus. We describe in detail Python implementations of classical algorithms, like Runge-Kutta, and more modern approaches, including physics-informed neural networks.


No Evidence Of Immune Priming In Bumble Bee Hosts Against Novel Exposure To A Honey Bee Virus, Austin Calhoun, Ben M. Sadd Jan 2025

No Evidence Of Immune Priming In Bumble Bee Hosts Against Novel Exposure To A Honey Bee Virus, Austin Calhoun, Ben M. Sadd

Faculty Publications – Biological Sciences

Ongoing global change presents novel challenges to species persistence, including heightened emerging infectious diseases (EID) exposure. While invertebrates lack vertebrate acquired immunity, many species exhibit “immune priming” with enhanced protection to repeated pathogen exposures. This phenomenon could be critical for species of conservation concern, such as for wild bumble bees, where EID risk is amplified through contact with managed bee pollinators. We investigate the potential for immune priming against the honey bee-derived Israeli Acute Paralysis Virus (IAPV) in Bombus impatiens bumble bees. We test the hypothesis that prior pathogen-associated exposure affords greater resistance and tolerance upon secondary pathogen exposure, due …

Sexually Antagonistic Coevolution Of The Male Nuptial Gift And Female Feeding Behaviour In Decorated Crickets, Samuel Burns-Dunn, Tassie Mortys, Clarissa M. House, Christopher Mitchell, Kristin R. Duffield, Bert Foquet, Ben M. Sadd, Scott K. Sakaluk, John Hunt Jul 2024

Sexually Antagonistic Coevolution Of The Male Nuptial Gift And Female Feeding Behaviour In Decorated Crickets, Samuel Burns-Dunn, Tassie Mortys, Clarissa M. House, Christopher Mitchell, Kristin R. Duffield, Bert Foquet, Ben M. Sadd, Scott K. Sakaluk, John Hunt

Faculty Publications – Biological Sciences

The evolution of nuptial gifts has traditionally been considered a harmonious affair, providing benefits to both mating partners. There is growing evidence, however, that receiving a nuptial gift can be actively detrimental to the female. In decorated crickets (Gryllodes sigillatus), males produce a gelatinous spermatophylax that enhances sperm transfer but provides little nutritional benefit and hinders female post-copulatory mate choice. Here, we examine the sexually antagonistic coevolution of the spermatophylax and the female feeding response to this gift in G. sigillatus maintained in experimental populations with either a male-biased or female-biased adult sex ratio. After 25 generations, males …
