Nutrient bioavailability and microbial responses in fresh and coastal aquatic ecosystems
Nutrients are the lifeblood of aquatic ecosystems, but not all nutrients are equally accessible to the organisms that depend on them. While traditional monitoring often tracks total or inorganic concentrations of carbon, nitrogen, and phosphorus, these measures do not reflect what microbial communities can actually use. This thesis explores that disconnect by investigating the bioavailability of k
