Analyses of variance for a) stem elongation (log transformed) 1996–1998, b) leaf length 1996–1998, c) cover 1995–2001, and (d) fruit production (log transformed) 1995–2000 of Silene acaulis. The factor and interaction effects are from a three factor ANOVA with Temperature, Nutrient and Year as fixed factors.
