World map using color coding to show the distribution of major floral kingdoms, subkingdoms, and regions. Key floral kingdoms include Boreal (green), Neotropical (pink), Paleotropical (yellow), South African or Capensic (purple), Australian (orange), and Antarctic (blue). Boundaries for subkingdoms, regions, and divisions are marked with different colored lines, and major regions such as Indoafrican, North American, and Malesian are labeled across continents.
World map displaying faunal realms and major animal regions, with color-coded areas representing the Holarctic, Paleotropical (Afro-Tethyan), Neogaean (Neotropical), Notogaean (Australian), and Oceanic realms. Major boundaries and notable regions such as Afrotropical, Oriental, Madagascan, Wallacea, Australian, and Hawaiian are labeled, and arrows indicate the hypothesized distribution of Antarctic fauna.
Map outlining the Malesian floral subkingdom in Southeast Asia and the Pacific, shaded and divided into three labeled regions: Western Division (covering Sumatra, Borneo, and surrounding areas), Eastern Division (including Mindanao, Moluccas, and New Guinea), and Southern Division (including Java). Division boundaries are marked, and major islands and seas are labeled for context.
World map showing major faunal regions as defined by mammalian distributions, with each region color-coded: Holarctic in green (including Nearctic and Palearctic), Afro-Tethyan in pink (including Mediterranean, Ethiopian, Oriental, and Madagascan), Latin American in tan (including Neotropical, Argentine, and West Indian), Island in yellow (including Australian and Madagascar). Major region boundaries are marked with bold lines.
Map of the Indonesian archipelago showing major faunal boundaries with colored lines: Wallace's Line in blue, Huxley's modification in red, Weber's Line in purple, and Lydekker's Line in green. These lines mark biogeographic divisions between Asian and Australasian animal species across islands such as Borneo, Sulawesi, Halmahera, and New Guinea.
