“Brown” World Invertebrates Contradict “Green” World Biodiversity Theory

Figure 1

Scatter plots with linear regressions of the average of the three sampling periods in 2005 data for (a) plant species richness versus standing crop plant biomass (g/m²), (b) invertebrate richness versus invertebrate biomass (g), (c) invertebrate richness versus plant biomass (g/m²), and (d) invertebrate richness versus plant species richness. Invertebrate data represent three 14-day sampling periods (4032 “traps nights,” or 96 traps × 14 nights open × 3 sampling periods) during which 46208 invertebrates were captured. –L and +L indicate plant litter biomass removed and plant litter biomass left in situ, respectively, and –F versus +F indicate no fertilizer and fertilized at 20 g N/m², respectively. ^** indicates regression significant at 𝑃<.0001.
