OverviewAI-generated summary

Felicia S. Osburn's research investigates the ecological and physiological factors influencing cyanobacteria, with a particular focus on nutrient dynamics and toxin production. Her work has explored how nitrogen and phosphorus availability impacts the growth, stoichiometry, and toxin production of both nitrogen-fixing and non-nitrogen-fixing cyanobacteria. Osburn has also examined the role of diazotrophy in modulating cyanobacteria's eco-physiological traits, which in turn influences bloom magnitude and the generation of toxins.

Her research extends to the broader ecosystem dynamics of aquatic environments. This includes studying lake stability and anoxia using high-frequency vertical profiling in eutrophic reservoirs, as well as investigating the variation and relevance of iron to phytoplankton ecology in Oklahoma reservoirs. Osburn's current work also delves into applying nonlinear thinking to ecology and evolution, utilizing the threshold elemental ratio concept across different ecological levels. She has published 16 papers, with an h-index of 5 and 143 citations.
