  1. Sample-size corrected Akaike weights (w AIC c ) and the number of yearly transitions (q) for density-independent models: random walk (RW), and exponential (EX), and density-dependent models: Ricker-logisitc (RL), Gompertz logistic (GL), and θ-logisitc (TL), of the population growth of southern elephant seals during the high-density era and low-density eras. The sum of the AIC c weights for the density-dependent models represents the combined percentage support for density dependence (%DD).
