FIGURE 5 in Threat patterns and conservation status of endemic vascular flora in Argentina: a quantitative perspective

FIGURE 5. Spatial patterns of threatened endemic species based on a spatial grid of 0.5 arc-degrees (~55 km). A. Map showing empirical (observed) species richness (SR) for threatened endemic species used to fit the models (response variable). B. Map of altitudinal heterogeneity (AH) used as predictor variable. C. Predicted SR for threatened endemic species using a generalized linear mixed model with fixed effects for AH and random effects for spatial distance. D. Partial effect of AH on SR, the blue line represents the average SR, the shadow area the 95% prediction intervals, and rugs the empirical values for variables. E. Scatterplot between observed SR and predicted SR values of threatened endemics in Argentina.
