ANOVA results for island size and species effects on lichen traits.

Results are from two-way split-plot ANOVAs testing for the effect of island size class (large, middle, small) as the main plot factor, and lichen species (M. olivacea, H. physodes and P. sulcata) as the sub-plot factor on specific thallus mass (STM) and medullary and cortical secondary compounds measured per unit mass as well as unit area.
df: IS = 2, 27, S = 2, 54, IS×S = 4, 54, except df for cortical compounds: IS = 2, 27, S = 1, 27, IS×S = 2, 27.
M. olivacea not included in ANOVAs for cortical compounds because all values were zero.
