Life Cycle. It is distinguished by its unique stripes, which are as distinctive as human fingerprints. A newborn zebra will follow anything that moves, so new mothers prevent other mares from approaching their foals while imprinting their own striping pattern, scent and vocalisation on them. The Grevy’s zebra is the largest of three zebra species with a thick rigid mane and large rounded ears. Grevy’s zebra live in herds but are loosely social animals that do not have concrete social systems.

Grévy's zebra is the largest of all wild equines.

These patrols aim to increase security on the ground for Grevy’s zebra and other wildlife and also establish the distribution on Grevy’s [...] This effect is increased when the group of zebras are running. Grévy's zebra differs from the other two zebras in its primitive characteristics and different behavior. Gestation of the zebra lasts 350 to 400 days, with a single foal being born. Grevy’s zebras are the largest of the three zebra species, including the plain and hybrid zebras. Eine weitere ältere Form wird durch Equus capensis aus Südafrika repräsentiert. 2008). [10] Grévy's zebra stallions have large testicles and can ejaculate a large amount of semen to replace the sperm of other males. [14]:147[15] It was extirpated from Somalia and Djibouti and its status in South Sudan is uncertain. [21] Zudem kann es aufgrund von Überschneidungen mit dem Verbreitungsgebiet des Steppenzebras zu Hybridbildungen kommen, was teilweise einen Einfluss auf die Bestandsentwicklung hat. Menelik II., ebenfalls König von Shewa und Kaiser von Abessinien, schickte ein Grevyzebra an Jules Grévy, den damaligen Präsidenten von Frankreich. Grevy's zebras can survive up to a week without water, but will drink daily when it is plentiful. Das Grevyzebra gehört weiterhin der eigenen Untergattung Dolichohippus an. [10], The Grévy's zebra was known to the Europeans in antiquity and was used by the Romans in circuses.

[10] The grévy's zebras main predator is the lion, but adults can be hunted by spotted hyenas. African hunting dogs, cheetahs and leopards almost never attack adults, even in desperate times, but sometimes prey on young animals, although mares are fiercely protective of their young. The Grévy's zebra lives in semi-arid grasslands where it feeds on grasses, legumes, and browse; it can survive up to five days without water. Die Beine sind lang und schlank geformt und enden in relativ kleinen, ovalen, aber pferdeartig breiten Hufen.

Jungtiere können auch Geparden oder Krokodilen zum Opfer fallen. [5] The stripes of the zebra may serve to make it look bigger than it actually is or disrupt its outline. [22] Mares may leave their foals in "kindergartens" while searching for water.

Ein paarungswilliger Hengst nähert sich einem Weibchen zunächst mit abmessenden Schritten, indem er die Fäkalien beriecht und ein flehmenartiges Rossigkeitsgesicht zeigt. It was the first zebra to emerge as a species. [10] Ecologically, this species is intermediate between the arid-living African wild ass and the water-dependent plains zebra. Traditionally, this species was classified in the subgenus Dolichohippus with plains zebra and mountain zebra in Hippotigris. Dabei gehört die Zebraform innerhalb dieser Gattung zur Gruppe der stenoninen oder non-caballinen Pferde. An invasive species, it is replacing the two grass species, Cenchrus ciliaris and Chrysopogon plumulosus, which the zebras eat for most of their food. Das Gebiss des Grevyzebras ist nicht reduziert und besitzt dementsprechend folgende Zahnformel: Eine kleine Gruppe von 30 Tieren wurde im Tsavo-East-Nationalpark eingeführt. [5] Notable examples include E. sanmeniensis from China, E. cautleyi from India, E. valeriani from central Asia and E. oldowayensis from East Africa. Continue to current page menu and content. [5] In the seventeenth century, the king of Shoa (now central Ethiopia) exported two zebras; one to the Sultan of Turkey and another to the Dutch governor of Jakarta. Watch closely to see how their ears move individually. 20 mm am unteren Anfang haben. These zebras weigh 350 to 450 kilograms (770-990 pounds). [1][7], Zahlreiche Parasiten sind beim Grevyzebra bekannt. They can often be seen on the open plains mingling with other grazing animals such as wildebeest, ostriches and antelopes. [10] Grévy's zebra stallions have large testicles and can ejaculate a large amount of semen to replace the sperm of other males. In freier Wildbahn … In freier Wildbahn ist das Grevyzebra aufgrund von Bejagung und durch Lebensraumverlust stark vom Aussterben bedroht. The Grévy's zebra was first described by French naturalist Émile Oustalet in 1882.

It is 2.5–2.75 m (8.2–9.0 ft) in head-body with a 55–75 cm (22–30 in) tail, and stands 1.45–1.6 m (4.8–5.2 ft) high at the withers. [13], Das Grevyzebra ist ein Vertreter der Gattung Equus, welche die heutigen modernen Pferde umfasst. There are three basic groups recognized in Equidae—horses, asses, and zebras—although all extant equids are in the same genus of Equus. Due to the stripes being closer together and thinner than most of the other zebras, it is easier for them to make a good escape and to hide from predators. [15] Embryological evidence has shown that the zebra's background colour is dark and the white is an addition. Their group composition changes regularly. Bedeutende Funde aus dem Holozän stammen aus der Dakhleh-Oase in Ägypten und datieren ins dortige Neolithikum. Allerdings ist die Population mit einem Rückgang von 94 Prozent seit den 1980er Jahren fast zusammengebrochen. Within the limits of law, your gift is 100% tax-deductible. The mane is tall and erect; juveniles have a mane that extends to the length of the back and shortens as they reach adulthood. [28]:17 Community-based conservation efforts have shown to be the most effective in preserving Grévy's zebras and their habitat. Grevy's Zebra The Grevy’s zebra is the largest living wild equid. [10] Mares require significantly more water when they are lactating. [21] They often migrate to better watered highlands during the dry season. Äthiopische Schutzgebiete umfassen unter anderem das Alledeghi-Wildschutzreservat, das Yabello-Schutzgebiet und das Chalbi-Schutzgebiet, kenianische den Meru- und den Shaba-Nationalpark sowie das Buffalo-Springs- und das Samburu-Nationalreservat. miles.

The modern Grévy's zebra arose in the early Pleistocene. [15] The call of the Grévy's zebra has been described as "something like a hippo's grunt combined with a donkey's wheeze". Dies geben auch Jungtiere von sich, die vom Muttertier getrennt wurden. Wasser trinkt ein junges Grevyzebra erstmals mit 3 Monaten. Grévy's zebra is limited to the Ethiopia and Kenya in the Horn of Africa, although it is possible they also persist in Sudan. Das schwach ausgebildete Nasenbein besitzt eine leichte Krümmung. 125 to 150 centimeters in length (50-60 inches), Lions, cheetahs, hyenas, hunting dogs, African wild dogs, leopards, humans. They also reach independence from the mare sooner than other equids. [5] Er besitzt eine charakteristisch langgezogene Schnauze, die das Grevyzebra deutlich vom Afrikanischen Esel (Equus asinus) oder Asiatischen Esel (Equus hemionus) unterscheidet. [23], Adult stallions mostly live in territories during the wet seasons but some may stay in them year round if there's enough water left. Grevy's Zebra suffered a severe population reduction between the late 1970s/early 1980s and the early 2000s, declining from a global population of around 15,600 individuals in the late 1970s/early 1980s (Williams 2002) to around 2,000 individuals in 2004.

[3], The Grévy's zebra is legally protected in Ethiopia. The stripes are narrow and close-set, being broader on the neck, and they extend to the hooves. [15] An oestrous mare may visit though as many as four territories a day[24] and will mate with the stallions in them. Like all zebras and asses, males fight among themselves over territory and females. [7] In areas where Grévy's zebras are sympatric with plains zebras, the two may gather in same herds[10] and fertile hybrids do occur. [15], Grévy's zebras can mate and give birth year-round, but most mating takes place in the early rainy seasons and births mostly take place in August or September after the long rains. A single individual may have a huge territory of up to 10 sq. Es hat eine Schulterhöhe von etwa 90 cm und wiegt rund 40 kg. Sie verschwindet beim Vermausern des Jugendhaares. Their group composition changes regularly. [3] It lives in Acacia-Commiphora bushlands and barren plains.
