Fig. 2. a) Life cycle graph of the didelphid marsupial Philander quica with a 2-month time step.?ge classes (j = juvenile; s = subadult; a = adult) are represented by nodes and transitions by arrows. py represents pouch young individuals; φ is apparent survival and Ψ is transition probabilities. b) Representation of the life cycle graph as a matrix population model. Pi (φi * Ψii) is the probability of surviving and staying in the same age class; Gi (φi * Ψij) is the probability of surviving and growing to the next age class; and Fi (φi * mi) is fertility of each sexually reproductive age class (mi = fecundity).
