Zoogeographic Regions

Faunal regions proposed by Alfred Russel Wallace, co-discover of the Theory of Evolution by Natural Selection.

Comparisons of the Mammals of the Faunal Regions [Table 25-1]

  1. Palearctic (PA)
    1. Europe, North Africa (to Sahara), Asia (except India, Pakistan and SE Asia) and Middle East.
    2. Number of families = 36; endemics = 1
  2. Nearctic (NA)
    1. Canada, USA, Mexico to tropics
    2. Number of families = 31; endemics = 2.

    Holarctic is Palearctic plus Nearctic

  3. Neotropical (NT)
    1. tropical Mexico south to South America, plus the Antilles
    2. Number of families = 56; endemics = 28.
  4. Afrotropic (AF) or Ethiopian (ET)
    1. Madagascar, Africa south of the Sahara, southern Arabian Peninsula
    2. Number of families = 58; endemics = 20.
  5. Indo-Malayan (IM) or Oriental (OR)
    1. Pakistan, India, Southeast Asia, Philippines, Indonesia west of Wallace's line (Sumatra, Java, Borneo)
    2. Number of families = 49; endemics = 8.
  6. Australian (AU)
    1. Australia, New Guinea, Tasmania, Indonesian Islands east of Wallace's line (Sulawesi, Timor, etc.)
    2. NOTE: does not include New Zealand
    3. Number of families = 35; endemics = 21.
  7. Oceanic
    1. Oceans of the world and truely oceanic, isolated, small islands
