In this paper we will use field and laboratory measurements on threshold size for flowering, survival, and growth rate collected for the facultative biennial herb Cynoglossum officinale in different habitats to (1) test the predictions from general life history theory that size at maturity should increase with increasing survival rate and/or size-dependent growth rate, and (2) compare the quantitative predictions from the three existing models by using the field data collected in different habitats.
We studied two populations of Cynoglossum officinale, at Meijendel in the Netherlands and Holkham in England.
The ecology of Cynoglossum officinale in Holkham was studied in 1973-1976 by Boorman and Fuller (1984).
We elaborated Inequality 3 further to fit the life history of Cynoglossum officinale by including the size-dependent functions for survival and growth from the moment the state is fixed (early winter) to the moment of flowering (spring).
Cynoglossum officinale thrives in places where rabbit grazing is heavy (Boorman and Fuller 1984).
In the case of Cynoglossum officinale presented here, populations are either declining (Meijendel) or strongly increasing (Holkham), as shown by the results of model A and C, and this may explain why the predictions deviate from observed threshold size values for [R.sub.0]-based models.
