AIC for different time (t)- and age (a)-dependent models of survival and recapture probabilities; np, number of parameters modeled; a*t, a model in which survival (or recapture) varies with age, time, and their interaction; a + t, the same model without interactions. a and t are models in which survival (or recapture) varies only respectively with age or with time. c, designates a model in which survival is assumed to be constant. The lower the AIC, the more appropriate the model to fit the data.
