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
Some species such as Pacific salmon migrate to reproduce; every year, they swim upstream to mate and then return to the ocean. [8] Temperature is a driving factor of migration that is dependent on the time of year. Many species, especially birds, migrate to warmer locations during the winter to escape poor environmental conditions. [9]
The researchers also concluded that during the hottest times of the day, zebras erect their black hair to release heat from the skin and flatten it again when it gets cooler. [65] Larison and colleagues (2015) determined that environmental temperature is a strong predictor for zebra striping patterns. [66]
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 ...

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.
The zebras were being transported from Washington to Montana when the driver took the Interstate 90 exit for North Bend, located about 30 miles (48 kilometers) southeast of Seattle, to secure the ...
Insect winter ecology describes the overwinter survival strategies of insects, which are in many respects more similar to those of plants than to many other animals, such as mammals and birds. Unlike those animals, which can generate their own heat internally ( endothermic ), insects must rely on external sources to provide their heat ...
