Figure 1. a) The coefficient estimates of the best fitting models from the second analysis (geometric growth rate ). Circles and bars show estimates and 95% CIs, respectively. The fixed effects were standardized (mean = 0, standard deviation = 1) prior to modeling, therefore the intercept shows the distribution of modeled geometric growth rate with mean values for population size and body mass. Also, coefficient estimates show the expected change in years to extinction given a one standard deviation increase in each fixed effect. Where CIs for a fixed effect do not overlap with zero demonstrates a positive or negative effect for that fixed effect, otherwise there is a mixture of positive and negative effects. Also, interaction plots are presented for b) all species, c) avian species and d) non-avian species. Error bars indicate 95% CIs.
Figure 2. a) The coefficient estimates of the best fitting models from the third analysis (population variability ). Circles and bars show estimates and 95% CIs, respectively. The fixed effects were standardized (mean = 0, standard deviation = 1) prior to modeling, therefore the intercept shows the distribution of modeled annual population variability with mean values for population size and body mass. Also, coefficient estimates show the expected change in years to extinction given a one standard deviation increase in each fixed effect. Where CIs for a fixed effect do not overlap with zero demonstrates a positive or negative effect for that fixed effect, otherwise there is a mixture of positive and negative effects. Also, interaction plots are presented for b) all species, c) avian species and d) non-avian species. Error bars indicate 95% CIs.
