Model-selection results for linear models of hoary marmot reproductive parameters.

Model-selection results for multistate CMR analyses of adult female hoary marmot survival and breeding probability in the Ruby Range, Yukon Territory from 1999–2004. Mark-recapture data were used to model the joint probability of three parameters: Apparent survival probability (S), the probability of breeding in a given year (Ψ), and detection probability (p). p was always modeled as a constant, and was estimated at 0.96 ± 02 (SE). Models are described in terms of the covariates used to constrain S and Ψ. In some cases, Ψ was modeled differently for young (2 year old) and old (3+ years) marmots. Descriptions and abbreviations for all covariates are in Table 1. K is the number of estimated model parameters, AICc is the Akaike Information Criterion corrected for sample size, Δ AICc reflects the difference in AICc between each model and the top model (smallest AICc),and ω is the model’s AIC weight.Model-selection results for linear models of hoary marmot reproductive parameters.
