Wallace Line

• The Wallace Line has gained attention in the news following recent research that offers fresh perspectives on the complex biogeographical patterns of Southeast Asia and Australia.
• The Wallace Line : A faunal boundary line separating the ecozones of Asia and Australia.
• Discovered by: Alfred Russel Wallace in 1863 during his explorations.

Location:

• Southern part: Intersects the Lombok Strait (between Bali and Lombok).
• Northern part: Passes through the Makassar Strait (between Borneo and Sulawesi).
• Significance:Divides Asian fauna (west) from Australian fauna (east).
• Example species:

1. West (Asia): Orangutans, tigers, rhinos.
2. East (Australia): Tree-kangaroos, Komodo dragons.

• Effects:
• Acts as a barrier for land animals, limiting species migration.
• Does not affect marine life.
• Wallacea: The transitional zone around the Wallace Line, known for high biodiversity.
• Scientific Importance: Helps in studying animal evolution and species distribution.
