Mapping of sampling bias effects of wild cacao species occurrences in Tropical Americas considering the main drivers for biasing effects (rivers, cities, airports and roads). At the study scale of 0.25 degrees, the mapping shows how river has a major effect in collection biasing for the specimens of this study. Sampling bias mapping analysis was conducted using the package "sampbias" v. 1.0.5 in R Environment (Zizka et al. 2020).
