Size-Dependent Flowering in relation to Grazing in a Short-Lived Monocarpic Perennial

Table 1

Results of the logistic regression using maximum likelihood estimates for the relationship between plant size, plant growth, and survival probability. WG+ = paddocks with winter grazing; WG− = paddocks without winter grazing. μ = intercept; and = regression coefficients of size and growth, respectively.
