While data are not yet as thorough for some taxa as for others, progress is being made. Below are some key studies that illustrate global patterns for other taxa. Each of these studies covers all or nearly all of a large-sized taxon, was published in a peer-reviewed scientific journal, and shows visually what the broad geographic patterns are for that taxon.
