Project Grant 2222519

This $218,479 project grant from the National Science Foundation's Division of Integrative Organismal Systems, under the Biological Sciences program (CFDA 47.074), will fund research on the adaptability of photosynthetic marine microorganisms' carbon dioxide concentrating mechanisms to changing climatic conditions. Specifically, the University of Colorado Boulder will experimentally evolve five phytoplankton groups with distinct CO2-concentrating mechanisms to quantify their plastic and adaptive carbon fixation responses to multiple climate change stressors expected in 2100 and 2500. The research aims to resolve how changes at the subcellular level contribute to organism-level carbon fixation responses, with implications for future ocean carbon sequestration. The award period is January 1, 2023 through December 31, 2025.
