Evaluating the interacting influences of pollination, seed predation, invasive species and isolation on reproductive success in a threatened alpine plant.

Floral display size, as measured by the log total number of florets, had a marginally significant positive association with log percent seed set ( Table 4 ).

When these six plants were removed from the dataset, the regression model explained much more of the variation in log percent seed set (R 2 = 0.77) and suggested an overwhelming role of plant isolation, with log distance to nearest flowering plant being highly significant and no other factors being close to significant ( Table 4 ).
