Sprouting by plants: the effects of modular organization

PA Vesk, M Westoby



1. Plant survival following disturbance was modelled simply as the probability that at least one of n stems sprouts, each stem having an independent probability of sprouting, s. This first-order model with any stem on any plant in any species having probability s = 0.18 of sprouting after clipping (s = 0.09 after burning) explained nearly half of the deviance associated with species' mortality in a field experiment on 43 species from a range of growth forms. 2. Allowing species to take either a low or high per-stem sprouting probability (SSP) improved statistical explanation substantially. Fitting growth form SSP was less effective, showing that much of the apparent among-species variation i..
