Ethiopian Region
•Africa South of Atlas Mts. and Sahara•Southern corner of Arabia•Land connection with Northern Neighbour•Otherwise isolated by sea•Has big rivers, Tropical evergreen forests, mountains and grassy plains like neotropical region but does not reach far into the southern temperate zone.•Large Madagascar island with its small neighbours is often included.

Ethiopian Region
Climate
• Mainly tropical• Large block of rain forests- equatorial west Africa• Many small patches of rainforests elsewhere• Rest of Africa covered by dry or seasonal thorn scrub or grassland
grading into desert northward and southwest ward.• Southern tip- warm temperate with complexly mixed vegetations

Ethiopian Region
Overview• Most varied fauna of all region• In no of endemic fam. Second to neotropical region• In fish, amphibia, reptiles it resembles both
neotropical and oriental region• In mammals and birds has strong affinity with
oriental region.• Similarities with both neotropical and oriental
regions because all three have a tropical climate• Stronger similarities with oriental because its
similarities are much more stronger with the tropics of the old world than those of the new world
![Page 50: Ethiopian](https://reader033.vdocument.in/reader033/viewer/2022061218/54b7ec674a795989078b4839/html5/thumbnails/50.jpg)
Ethiopian Region
Overview• As a whole, vertebrate fauna is most like the
Oriental one– the two are roughly similar in size and in
composition– they share many fam., v. many genera and some sp.
• Parts of the fauna have close relationships with Palearctic – principally by northward extension of tropical
groups including many migratory birds and certain fam., genera and species of other vertebrates
![Page 51: Ethiopian](https://reader033.vdocument.in/reader033/viewer/2022061218/54b7ec674a795989078b4839/html5/thumbnails/51.jpg)
Ethiopian Region
Overview• Some parts of fuana more distantly related to
Neotropical region– Include several imp grps of fishes, certain
amphibians and reptiles but v few birds and mammals
• Hardly any direct relationships – b/w Ethiopian and Australian region – b/w Ethiopian and Nearctic region.
![Page 52: Ethiopian](https://reader033.vdocument.in/reader033/viewer/2022061218/54b7ec674a795989078b4839/html5/thumbnails/52.jpg)
Ethiopian Region
Overview• Fauna is richest and most varied in more tropical
areas.• A strong general reduction of fauna northward into
Sahara and less strong reduction and some differentiation southward into South Africa.
• Some differentiation of a west African wet forest and an east African open forest and steppe fauna, although the two overlap and mix complexly.
• These general differences led Wallace to divide the region into 3 subregions: West Africa, East Africa and South Africa
