Population dynamics model transition matrix of teasel

Description

Transition matrix of the population dynamics model of teasel (Dipsacus sylvestris), a European perennial weed, as discussed in Caswell (2001), and in Soetaert and Herman, (in prep)

The life cycle of teasel can be described by six stages:

The matrix contains the transition probabilities from one compartment (column) to another (row)

Usage

Teasel

Format

matrix with transition probabilities, where element ij denotes transition from compartment j to i
rownames and columnames are the component names
