1. Schonberger, Zachariah G. Understanding Ecosystem Dynamics within a Modular Framework.

Degree: MS, Department of Integrative Biology, 2020, University of Guelph

Food web theory has been successful in using energetic models to understand how food webs are stabilized in space and time. In parallel, ecosystem theory has employed nutrient-limited ecosystem models to understand how limiting nutrients alter the structure and dynamics of food webs. Importantly, while food web theory has gained fundamental insights using a modular framework, ecosystem theory has largely overlooked the role of a key module – the autotroph-limiting nutrient (R-N) module – in modulating the dynamics of nutrient-limited ecosystem models. Here, I revisit the inherent stability of the R-N module and establish strong R-N interactions as potent stabilizers in higher order systems. I do this by first revisiting consumer-resource (C-R) theory and highlight the relationship between the structure of C-R interactions and predictable dynamical outcomes. I then translate this framework to R-N-based systems, showing the R-N module to behave as a coherent extension of current modular food web theory. Advisors/Committee Members: McCann, Kevin (advisor).
