Notes: Approximately twenty individuals of each phase were collected at each site, during each sampling date. Reproductive blade area was calculated from a length/width : area regression previously established. Spore density was calculated from the number and size of reproductive structures on blades. Fecundity was calculated from the total reproductive blade area and the average spore density of each individual sampled.
