Overall, the modifications led to a change from a total of 1,983,482 occurrences to 2,212,446 occurrences in 110 × 110 km cells (1,073,129 to 1,298,365 occurrences for non-marine mammals and 67,306 to 242,960 occurrences for megafauna). A detailed explanation of the different types of modifications can be found in supplementary methods. (B) Estimated diversity All diversities were estimated on a Behrman projection of the world with equally sized grid cells with 360 columns (i.e., 1° by 1° cells at the equator, roughly equal to 110 × 110 km grid cells). Diversities were estimated for five mammalian subgroups: 1) all species, 2) 3) 4) and 5) non-marine species, terrestrial species, large terrestrial species, For species coded as exclusively marine by terrestrial megafauna. non-marine species, IUCN (most cetaceans and two manatees), as well as pinnipeds coded as and “marine and three effectively marine non-pinniped carnivores (Ursus (polar terrestrial” maritimus bear), (sea otter) and (marine otter)), were removed, whereas Enhydra lutris Lontra felina species coded as and such as (harbor seal) or Phoca vitulina “freshwater marine”, manatees of the genus were deleted from all fully or partially marine cells.
