This research investigates how the alga Epithemia sustains productivity in California's Eel River by fixing atmospheric nitrogen. Using stable isotope analysis, it shows that Epithemia supplies almost all the nitrogen supporting algal growth, revealing a critical ecological process underpinning river food webs and the conservation of salmon ecosystems.

This research investigates how freshwater organisms respond to climate extremes such as warming rivers and drought. Using field surveys, experiments, and modelling, it examines whether species can adapt to higher temperatures and what costs that adaptation may carry. Understanding these limits is crucial for protecting ecosystems, water security, and biodiversity.

This research uses freshwater mussels as bioindicators to investigate water quality in Darby Creek. Community science data revealed links between elevated chloride pollution, likely from road salt, and declining mussel populations. The discovery of a healthy mussel population highlights both the importance of local monitoring and opportunities for targeted watershed restoration.
