Determinants and Congruence of Species Richness Patterns across Multiple Taxonomic Groups on a Regional Scale

Figure 3

Correlations of species richness for different taxa with environmental parameters in 184 grid cells: (a) number of grasshopper species and mean annual temperature, GLM (with poisson errors), 32% deviance change, 𝑃<0.001, (b) number of grasshopper species and proportion of meadows and pastures, GLM (with poisson errors), 36% deviance change, 𝑃<0.001, (c) number of plant species and index of aridity, GLM (with quasipoisson errors), 23% deviance change, 𝑃<0.001, (d) number of moss species and mean sum of annual precipitation, GLM (with quasipoisson errors), 6% deviance change, 𝑃<0.01.
