Proportional C4 cover and richness at TERN monitoring plots.
(a, b) Poaceae, (c, d) Cyperaceae, (e, f) Chenopodiaceae, and (g, h) Euphorbiaceae.
Fig 2.
Binomial logistic regressions of proportional C4 Poaceae richness.
Grey points are partial residuals, blue lines and shaded bands are predicted outcomes of the regression and 95% confidence intervals respectively, and rugs were drawn to indicate observations with positive residuals (top of the plot) or negative residuals (bottom of the plot). For each plot (A-D), independent variables not depicted on the x-axis are held constant at their median value.

Binomial logistic regressions of proportional C4 Cyperaceae richness.
Grey points are partial residuals, blue lines and shaded bands are predicted outcomes of the regression and 95% confidence intervals respectively, and rugs were drawn to indicate observations with positive residuals (top of the plot) or negative residuals (bottom of the plot). For each plot (A-C), independent variables not depicted on the x-axis were held constant at their median value.
