Table 1.
The most parsimonious survival models for males and females (S denotes survival, P denotes recapture probability), including model deviance, number of parameters (np) and Akaike's information criterion (AICc=deviance +2np) and the difference in AICc compared to the most highly ranked model (ΔAICc). The letter t indicates time (i.e. annual variation) and g the zone-dependence (i.e. polluted versus non-polluted zone). The models in boldface, with lowest AICc, were used for interpretation of results.
