   Notes: Matrices were compared excluding fecundity and adding death as a fate. A constant 0.5 was added to all cells prior to analysis. The explanatory variables are population (P) and year (Y). The response variable is the fate F of individuals at time t + 1 conditional to their state S at time t. The null model is defined as SYP, SF. The best model is marked in gray.
