The five most parsimonious generalized linear mixed-effects models investigating (a) life history correlates of threat risk (n = 2,494) and (b) environmental context, after accounting for effects of range and body size (n = 2,584). Models include nested (hierarchical) taxonomic (Order/Family) random intercepts and geographic distance random slopes to account for spatial autocorrelation. Models were ranked according to the Bayesian Information Criterion (BIC). For ecology/life history models, the five most highly BIC-ranked models accounted for >99 % of the posterior model weight (wBIC) of the total of 40 models considered. For environmental context, model weights were more evenly distributed among the 5 most highly ranked of the 75 models considered. Terms shown are RG = range (km²), BS = body size, HB = habit, RC = reproductive cycle, PC = presence/absence of parental care, and FT = fertilization type, TM = mean temperature, PV = precipitation range, PM = mean precipitation, TV = temperature range, HL = % habitat lost, HD = human density (people/km²) Also shown are number of parameters (k), maximum log-likelihood (LL), difference in BIC for each model from the most parsimonious model (ΔBIC) model weight (wBIC), percent deviance explained (%DE) in the response variable (threat probability) by the model under consideration, and the difference between the %DE for the current environmental context model and the base ∼BS+RG model (Δ%DE).
