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

Table 2

Observed survival probability for different size and growth classes in both grazing treatments. In parenthesis there is the predicted probability (maximum likelihood estimate). Size: the broadest rosette diameter (cm) in February 1998. Growth: relative increase in size, in the period between February 1998 and May 1998. “—” indicates that no plant within the respective size and growth range was observed.
