This $506,276 National Science Foundation project grant supports research investigating the relationship between cell size and nutrient acquisition modes in mixotrophic protists. Funded under the NSF's Geosciences program (CFDA 47.050), the research aims to establish an empirical understanding of how mixotroph cell size relates to dependence on photosynthesis versus prey ingestion. The Virginia Institute of Marine Science will lead experiments measuring the carbon obtained from each mode...
This five-year, $446,360 project grant from the National Science Foundation's Biological Sciences program (CFDA 47.074) will fund research quantifying functional diversity among mixotrophic and heterotrophic microbes in the ocean. The University of Hawaii at Manoa will examine how mixotrophy, the ability to photosynthesize and consume other microbes, changes energy and nutrient flows through microbial food webs. Researchers will conduct in situ and laboratory experiments comparing predation...
The National Science Foundation (NSF) Division of Ocean Sciences awarded a Project Grant totaling $690,714 to the Massachusetts Institute of Technology (MIT) to conduct research on the direct measurement of in situ growth and growth limitation of bacterioplankton species in the ocean. The research is funded through the NSF Geosciences program (CFDA 47.050), which supports basic research to expand fundamental knowledge and understanding of the integrated Earth system. The key objective of this...
This $1.79 million National Science Foundation Project Grant under the Geosciences program (CFDA 47.050) funds research at Woods Hole Oceanographic Institution from July 2022 through June 2025 to investigate mixotrophic algal contributions to copepod diet and reproduction in the Gulf of Maine. The award supports experiments to characterize the role of mixotrophic algae in mitigating deficiencies in phytoplankton food quality for copepod reproduction. Analysis of nutrient and fatty acid...
This $493,073 Project Grant from the National Science Foundation's Biological Sciences program (CFDA 47.074) supports collaborative research at the University of California, Santa Barbara (UCSB) on the evolutionary processes that enable a genus of ciliates known as Mesodinium to acquire and maintain phototrophy through organelle sequestration. The 3-year project will use comparative cellular, metabolic, and genetic analyses to understand the adaptations that allow some Mesodinium species to...
This $300,785 federal Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) supports a research project to characterize the chemical composition and bioavailability of dissolved organic matter released by marine nitrifying microorganisms. The project aims to determine how this material contributes to carbon cycling in the deep ocean, which may help improve biogeochemical models and inform potential marine carbon dioxide removal activities. The research will...
This National Science Foundation (NSF) Project Grant award under the Geosciences program (CFDA 47.050) provides $315,954 to Portland State University to conduct research on the effects of microbial cell surface properties on predator-prey interactions in marine ecosystems. The 3-year project aims to quantify the surface characteristics of major marine microbial groups and assess how these properties influence feeding selectivity and fate of particles by suspension-feeding organisms like...
This National Science Foundation Project Grant of $539,985 supports research into the stoichiometric trait distribution of the marine microbiome. Funded through the Geosciences program under the Division of Ocean Sciences, the award will quantify the relationship between environmental conditions and the carbon, nitrogen, and phosphorus ratios in marine microbes. Over three years, the researchers from Colorado State University will characterize the biomass elemental composition of 50 marine...
This National Science Foundation Project Grant of $597,248 supports research into applying novel approaches to link microbial growth efficiency, function, and energy transfer in the ocean.

Specifically, the University of Miami Rosenstiel School of Marine and Atmospheric Science will conduct research from September 2023 to August 2026 to...
This Project Grant from the National Science Foundation Division of Ocean Sciences, under the Geosciences federal grant program (CFDA 47.050), provides $279,809 to the University of California Irvine to quantify the relationship between environmental conditions and the particulate carbon, nitrogen, and phosphorus ratios of marine microorganisms. Over the three-year period from February 2022 to January 2025, the researchers will characterize the distribution of biomass stoichiometric traits for...

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.
