ALT A graph showing Net Primary Productivity (NPP) in relatively natural vegetation types against the NPP difference between the natural and human modified systems. In places with low initial NPP human modification increases NPP, in places with higher initial NPP it decreases. Major modifications have slightly more extreme effects than minor ones.
ALT Graphs showing the relationship between species richness difference and net primary productivity (NPP) difference for different relatively natural land cover types. Richness differences are the log10 of the proportional species richness differences between every modified site (MV) and the mean value of relatively natural sites (RNV) for a specific land-cover type in the same substudy. Year-averaged NPP shown; adjusting cropland productivity for human appropriation. Single circles indicate the mean species richness difference values for each relatively natural land-cover type and modification combination within substudies (vertical and horizontal lines show standard deviations). There's no obvious patterns anywhere, really!
