Summary of the parameter coefficients for the best model for mammal identification.

We modeled the frequency of identifications at a particular level using a Poisson (link = log) GLMM, with village and respondent nested within village included as random effects (not shown). We investigated the effect of respondent gender, respondent age, and species abundance (extant vs extirpated) and their interactive effects on the ability of people to correctly names species at two levels (overall (group + species levels) and specific (species vs groups levels)). The interactive terms were removed during model simplification. Although models including the interactive terms were roughly equivalent (Table 3), none of the coefficients for the interactive terms were significant. Full model details are given in the online supplementary material Table S3.
