Fig. 3: Distribution of field sampling and study citations across environmental space represented by natural terrestrial habitats in the tropics.

Frequency distribution of actual occurrence (A, D, G, J), sampling locations (B, E, H, K) and citations (C, F, I, L) for different combinations of environmental conditions across natural terrestrial habitats in the tropics. Values are derived from a database of 2738 articles, representing 6370 sampling locations and 89,468 citations. The tropics are defined using widely accepted boundaries23. Gray pixels denote the full range of ambient conditions across the entire tropics, from a random sample (n = 100 000) of the total pixels within the study area. To be representative, sampling locations (B, E, H, K) and citations (C, F, I, L) should cover the full range of environmental conditions shown in gray and display a frequency distribution similar to the actual occurrence of environmental conditions (A, D, G, J) observed across the entire tropics.
