The University of Oregon was awarded a $622,198 Project Grant from the National Science Foundation's Geosciences Program (CFDA 47.050) to conduct collaborative research on the effects of particle surface properties on predator-prey interactions among marine microorganisms. This 3-year project, beginning on September 1, 2024, aims to advance the scientific understanding of carbon fate and nutrient cycling in the ocean by examining how microbial surface characteristics influence their selection and rejection by globally abundant suspension feeders. The research involves quantifying the surface properties of major marine microbial groups, conducting controlled laboratory feeding experiments with artificial microspheres, and analyzing the gut contents of wild-caught suspension feeders. This integrative approach is expected to provide foundational knowledge for future ocean food web models and engage public audiences through exhibits, workshops, and large-scale art installations focused on ocean ecosystems and predator-prey interactions.
