^a2007 abundance in natural populations assuming a Poisson error distribution—Hx. arifolia. Quasi-Poisson error distribution, with t-value, owing to overdispersion.

^b2007 adult survival in experimental plots assuming a binomial error distribution.

^c2007 recruitment success in experimental plots assuming a binomial error distribution.
