  1. Effects of time (t), and age (age-juvenile/adult) on the probability of survival (ϕ) and recapture (p) of southern elephant seals during the high- (1951–1964) and low-density (1993–1999) eras. Models are ranked according to their Akaike weights (w QAIC c ), the relative change in AIC c score (ΔQAIC c ), and number of parameters (k) based on an inflation factor (ĉ) of 1.3664.
