The Moeller Lab, in collaboration with Emma Goldberg (UMN EEB) and Yaniv Brandvain (UMN PMB), received four years of funding ($974,762) to investigate the role of mating system transitions in plant speciation. This new funding continues past work that revealed reproductive character displacement between incipient Clarkia species, and provided evidence of reinforcement in secondary sympatry. The new project integrates mathematical modeling, field experimentation, and genomic analysis.
