This three-year, $536,104 National Science Foundation Project Grant under the Geosciences program (CFDA 47.050) supports research investigating the relationship between cell size and nutrient acquisition modes in mixotrophic protists. The awardee, Bigelow Laboratory for Ocean Sciences, will conduct incubation experiments on eight mixotrophic species to measure the proportion of carbon obtained from photosynthesis and ingestion across environmental conditions. Using isotopic labeling methods, the researchers will assess how cell size relates to trophic strategies in mixotrophs with the goal of developing a generalized understanding of carbon transfer in marine ecosystems. Broader impacts include training opportunities for early-career researchers, graduate students, undergraduates, and K-12 science teachers. Findings aim to transform the understanding of mixotrophs' roles in plankton communities and biogeochemical cycling, improving ecosystem models and predictions under changing ocean conditions.
