In the desert there are areas which are much bigger than the areas of the tundra so Capcoom made the Barioth Subspecies bigger than the regular one. Agnaktor Subspecies is smaller because there is not enough space for a regular sized Agnaktor. And Giggnox does not change the map, so it does not have to become bigger.
