Effects of age (age-juvenile/adult), time (t), density of breeding females (density), density of breeding females lagged by one year (dlag) and environmental conditions (SOI during a newly weaned seal's foraging period [pup] and during a mother's pre-partum foraging period [mother] on the probability of survival (ϕ) of southern elephant seals during the high- (1951–1964) and low-density (1993–1999) eras. Models are ranked according to their Akaike weights (wQAICc), the relative change in AICc score (ΔQAICc), and number of parameters (k), based on an inflation factor (ĉ) of 1.7122. | |||
