Fig. 2: Representativeness of currently sampled 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. Values represent probabilities (1 = high, 0 = low) that environmental conditions within a location have been sampled, using statistical multivariate modeling16. A value above 0.5 effectively classifies an environmental condition as one where a sampling location is present. Photographs show the locations of the top five most cited (red outline and arrow) and least cited (black outline and arrow) ecoregions across the terrestrial tropics23. Photo credits in Supplementary Table 1. Data of locations and citation metrics across the full list of ecoregions are presented in Supplementary data 1. Base map from Esri99.
