Determine germination thresholds of native and weed species from a Mixed-grass Prairie global change experiment.
Seeds from plants growing in the Prairie Heating and CO2 Enrichment Experiment will be collected and sent to the University of Saskatchewan. A suite of measurements/tests will be conducted, including: germination test for thermal time model, germination test for hydrothermal time model, seed viability, seed mass, seed C and N. Data will be analyzed, including the use of seed models to evaluate how elevated CO2 and warming affect seed/seedling physiology.
