ASPECTS REGARDING THE CONFORMATION AND STRUCTURE OF THE RETE MIRABLE EPIDURALE AT SHEEPS

摘要

Africa has been and will be the poster child of global biodiversity for ages. One-fourth of Africa's biodiversity is in Ethiopia, and is comprised of 320 mammals, 860 birds, 240 reptiles, 71 amphibians, 150 freshwater fish, and over 1,225 arthropods and 6,600 plant species with a high rate of endemism. The endemic wildlife include the Ethiopian wolf and Swayne’s hartebeest, Prince Rasploi’s turaco and Stresemann’s bush crow, Bale mountains heather chameleon and the Ethiopian mountains adder, and the Ethiopian banana frog and Bale mountains moss frog. There are diverse habitats ranging from 110 meters below sea level at Kobar Sink in the Afar depression, to a peak of 4620 meters above sea level at Ras Dejen in the Siemen Mountains. The high relevance of wildlife management in Ethiopian universities is therefore a given.
