USGA Summary Points:Accessed, organized, and grew to pure culture, 17 genotypes of Bryum argenteum from golf course putting greens and 17 genotypes of B. argenteum from native habitats, for purposes of comparing their life history and stress responses. Conducted a six-month life history experiment using the 34 cultures above, and including a treatment of nutrients vs. no nutrients. Our major findings, published in Weed Science, are that plants from putting greens diverge from plants from non-putting green habitats in (i) growing much faster both laterally and vertically, (ii) colonizing more quickly, (iii) producing more shoots, (iv) producing more aerial rhizoids (specialized extensions from the shoots to anchor it among the grasses and likely functioning in making space for the moss plants), and (v) focusing energy on asexual reproduction through shoot fragments rather than sexual reproduction or even specialized asexual reproduction. Based on the findings from this experiment, we concluded that either (i) recent natural selection pressures have yielded a species with a combination of traits adapted to putting green survival, or (ii) successful genotypes of the species are preexisting in the native environment, and only these strains survive the putting green environment. Designed and implemented an experiment testing the tolerance of putting green and native B. argenteum genotypes to carfentrazone concentrations, light intensity variation, and surfactant concentrations. This experiment in progress has already yielded evidence of recent natural selection on putting green strains indicating resistance to carfentrazone. In addition, the most promising avenue of future research involves the development of a surfactant to treat infestations of this moss in putting greens.
