(a) Relationship between the mean human footprint in each of 24 Mexican ecoregions, and the standard deviation of their footprint values (r2 = 0.99;P < 0.00001). (b) Relationship between mean human footprint in each ecoregion and the skewness of the distribution of footprint values (r2 = 0.87; P < 0.00001). (c) Relationship between mean human footprint and the mean patch size of low footprint area in each ecoregion (r2 = 0.84; P < 0.00001; in all cases the fitted curve was obtained using polynomial regression).
Large differences in ecoregional HF values (white points) were observed within most biomes (black points). Biomes names as follow Great Plains (GP), Mediterranean California (MC), North American Deserts (NAD), Southern Semi-Arid Highlands (SSAH), Temperate Sierras (TS), Tropical Dry Forests (TDF) and Tropical Humid Forests (THF).
