Mountain zebras live in hot, dry, rocky, mountainous and hilly habitats. They prefer slopes and plateaus as high as 2,000 m (6,600 ft) above sea level, although they do migrate lower during winter. Their preferred diet is tufted grass, but in times of shortage, they browse, eating bark, twigs, leaves, buds, fruit, and roots. They drink every day.
Equus originated in North America and direct paleogenomic sequencing of a 700,000-year-old middle Pleistocene horse metapodial bone from Canada implies a date of 4.07 million years ago (mya) for the most recent common ancestor of the equines within a range of 4.0 to 4.5 mya. [20]
Zebras have a less efficient digestive system than ruminants but food passage is twice as fast. [15] Thus, zebras are less selective in foraging, but they do spend much time eating. The zebra is a pioneer grazer and prepares the way for more specialised grazers such as blue wildebeests and Thomson's gazelles. [9] Lions feeding on a zebra
Ever wondered why zebras have stripes? Well, the researchers behind a new study think they have a pretty good answer to that question. WMAQ reports "California scientists say the animal's black ...
Why do zebras have stripes? The answer to that question, which scientists have wrestled with for over a century, may be most related to temperature. It was previously thought that the stripes ...
The winter following the fires many old moose died, probably as a combined result of the loss of good moose forage and a harsh winter. The fires forced some moose into poorer habitats, with the result that some almost doubled their home range, using deeper snow areas than previously, and sometimes browsing burned lodgepole pines.

Zebras appear to be a monophyletic lineage [10] [11] [12] and recent (2013) phylogenies have placed Grévy's zebra in a sister taxon with the plains zebra. [10] In areas where Grévy's zebras are sympatric with plains zebras, the two may gather in same herds [13] and fertile hybrids do occur. [14]
