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]
In Southern California, the temperature differences are approximately 4 °F in winter and 23 °F (2 °C and 13 °C) in summer. At the coast in Santa Monica , the average high in August is 75 °F (24 °C), while in Burbank , approximately 10 miles (16 km) inland, the average high in August is 95 °F (35 °C): a temperature gain of about two ...
WMAQ reports "California scientists say the animal's black and white pattern helps keep flies away by Well, the researchers behind a new study think they have a pretty good answer to that question.
Zebras may spend 60–80% of their time feeding, depending on the availability of vegetation. [ 9 ] [ 29 ] The plains zebra is a pioneer grazer, mowing down the upper, less nutritious grass canopy and preparing the way for more specialised grazers like wildebeest , which depend on shorter and more nutritious grasses below.
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.
Astronomical winter begins on the winter solstice, which is the shortest day of the year when the North Pole is tilted away from the sun. This year that's Saturday, Dec. 21, which will be 5:21 a.m ...
Aestivation (Latin: aestas (summer); also spelled estivation in American English) is a state of animal dormancy, similar to hibernation, although taking place in the summer rather than the winter. Aestivation is characterized by inactivity and a lowered metabolic rate, that is entered in response to high temperatures and arid conditions. [ 1 ]
