Appendix A. Comparing support of the covariates weight and sex in mark-resight models.

Table A1. Results of model selection for mark-resight analyses comparing the influence of the covariates weight (weight (kg) of animal) or sex (male or female) on the parameters α and σ for bobcats and pumas on the Western Slope (WS) and Front Range (FR) of Colorado, USA.

a α = alpha (intercept for mean resighting rate); σ = sigma (individual heterogeneity level)

b Due to lack of model convergence when multiple covariates were evaluated for the parameter sigma, one covariate was evaluated for each parameter in models for comparisons.
