Biography

Timothy Bartley is an Assistant Professor in the College of Biological Science at the University of Guelph. He specializes in ecology with a focus on food web dynamics, particularly in the context of global environmental change. His research examines the causes and consequences of food web reorganization, utilizing empirical data from Great Lakes aquatic ecosystems to understand organismal responses to environmental alterations. Bartley's PhD work investigated the responses of entire lake food webs to natural climate gradients in Ontario, Canada, revealing significant shifts in fish community structures linked to increasing temperatures. He employs dietary data, stable isotope analysis, and molecular gut content analysis to infer behaviors and track responses of aquatic communities, highlighting the flexibility of food web structures under climate stress. His research aims to develop theoretical models that explore the impacts of food web rewiring on ecosystem stability.
