Table 2.
Model comparison table to estimate annual kitten survival and select t base model. For each model, we present the number of parameters (K), the difference from the top model in Akaike’s Information Criterion adjusted for overdispersion and small sample size (ΔQAICc), the model QAICc weight, and the estimate of annual kitten survival with standard error. The base model selected is in bold (representing survival differing between kittens, females age 1 and 2, females 3 and older, males age 1-3, and males 4 and older; recapture the same for all uncollared panthers; and recovery differing between uncollared kittens and uncollared older panthers).
