Zebra, asiatic ass migrations left in tatters http://apocadocs.com/s.pl?1259248851
Southern Africa's plains zebras and the asiatic wild ass have been identified among animals whose migratory habits have been left in tatters.
A quarter of the world's migrating species are suspected to no longer migrate at all because of human changes to the landscape, and all of the world's large-scale terrestrial migrations have been severely reduced.
A recent research paper has presented the first analysis of dwindling mass migrations, and noted the plight of the plains zebra (Equus quagga) and the asiatic wild ass (Equus hemionus), which live in central Asia.... All 24 species in the current study lost migration routes and were reduced in number of individuals.
The analysis found drastic curbing for six species in particular -- the plains zebra, asiatic wild ass, the springbok (Antidorcas marsupialis), black wildebeest (Connochaetes gnou), the blesbok (Damaliscus dorcas) and the scimitar horned oryx (Oryx dammah) of northern Africa.
These species either no longer migrate or are impossible to evaluate as migratory animals.
