Aim To determine whether the method used to build distributional maps from raw data influences the representation of two principal macroecological patterns: the latitudinal gradient in species richness and the latitudinal variation in range sizes ( R apoport's rule). Location World‐wide. Methods All available distribution data from the Global Biodiversity Information Facility ( GBIF) for those fish species that are members of...
