  1. A. The effect of species (the three moss species which produced sporophytes during the experiment), treatment (OTC and control), site (Juan Carlos Point and La Cruz Plateau), and interactions between these factors on sporophyte production analyzed using a generalized linear model with a Poisson distribution. B. The effect of species (H. antarctica and B. patens), treatment (OTC and control), and interactions between these factors on sporophyte size analyzed using ANOVA. Significant p-values are shown in bold
