This $433,365.00 Project Grant award from the National Science Foundation's Biological Sciences (CFDA 47.074) Federal Grant Program supports a collaborative research project to investigate how increased nutrient availability in Tonian-period oceans (1000-720 million years ago) may have driven the diversification and ecological rise of eukaryotic organisms. The research, led by Virginia Polytechnic Institute & State University, involves collecting and integrating paleontological, geochemical, sedimentological, and stratigraphic data from early and late Tonian strata in North China and the Grand Canyon to reconstruct nutrient availability, eukaryote biodiversity, and marine geochemical cycles. This research aims to illuminate the complex feedbacks between nutrient availability, functional biodiversity, and biodiversity dynamics during a major transition in Earth's history. The project also offers opportunities for STEM workforce training and public outreach activities engaging national parks.
