The term antelope refers to numerous extant or recently extinct species of the ruminant artiodactyl family Bovidae that are indigenous to most of Africa , India , the Middle East , Central Asia , and a small area of Eastern Europe . Antelopes do not form a monophyletic group, as some antelopes are more closely related to other bovid groups, like bovines , goats , and sheep , than to other antelopes.

86-454: Capra gazella Linnaeus, 1758 The gemsbok ( Oryx gazella ), or South African oryx , is a large antelope in the genus Oryx . It is endemic to the dry and barren regions of Botswana , Namibia , South Africa and (parts of) Zimbabwe , mainly inhabiting the Kalahari and Namib Deserts , areas in which it is supremely adapted for survival. Previously, some sources classified

172-491: A lion until it is closer than 200 m (650 ft)—lions hunt as a pride or by surprise, usually by stalking; one that can be seen clearly is unlikely to attack. However, sprint-dependent cheetahs will cause gazelles to flee at a range of over 800 metres ( 1 ⁄ 2 mile). If escape is not an option, antelope are capable of fighting back. Oryxes in particular have been known to stand sideways like many unrelated bovids to appear larger than they are, and may charge at

258-672: A vegetable , stir-fried or stewed . Citrullis lanatus , variety caffer , grows wild in the Kalahari Desert , where it is known as tsamma . The fruits are used by the San people and wild animals for both water and nourishment, allowing survival on a diet of tsamma for six weeks. The watermelon is used variously as a symbol of Palestinian resistance , of the Kherson region in Ukraine, and of eco-socialism , as in 'green on

344-638: A common origin, possibly cultivated in the Nile Valley by 2340 BC. Watermelon fruit is 91% water , contains 6% sugars, and is low in fat (table). In a 100-gram ( 3 + 1 ⁄ 2 -ounce) serving, watermelon fruit supplies 125 kilojoules (30 kilocalories) of food energy and low amounts of essential nutrients (see table). Only vitamin C is present in appreciable content at 10% of the Daily Value (table). Watermelon pulp contains carotenoids , including lycopene . The amino acid citrulline

430-430: A distance, the only outward difference between males and females is their horns, and many hunters mistake females for males each year. In males horns tend to be thicker with larger bases. Females have slightly longer, thinner horns. Female gemsbok use their horns to defend themselves and their offspring from predators, while males primarily use their horns to defend their territories from other males. Gemsbok are one of

516-575: A fear response to perceived predators, such as humans, making them very difficult to herd or handle. Although antelope have diets and rapid growth rates highly suitable for domestication, this tendency to panic and their non hierarchical social structure explains why farm-raised antelope are uncommon. Ancient Egyptians kept herds of gazelles and addax for meat, and occasionally pets. It is unknown whether they were truly domesticated, but it seems unlikely, as no domesticated gazelles exist today. However, humans have had success taming certain species, such as

602-535: A forest environment with patchy resources, and a male is unable to monopolize more than one female due to this sparse distribution. Larger forest species often form very small herds of two to four females and one male. Some species, such as lechwes , pursue a lek breeding system, where the males gather on a lekking ground and compete for a small territory, while the females appraise males and choose one with which to mate. Large grazing antelope, such as impala or wildebeest , form large herds made up of many females and

688-826: A juice or an ingredient in mixed beverages. Kordofan melons from Sudan are the closest relatives and may be progenitors of modern, cultivated watermelons. Wild watermelon seeds were found in Uan Muhuggiag , a prehistoric site in Libya that dates to approximately 3500 BC. In 2022, a study was released that traced 6,000-year-old watermelon seeds found in the Libyan desert to the Egusi seeds of Nigeria , West Africa. Watermelons were domesticated in north-east Africa and cultivated in Egypt by 2000 BC, although they were not

774-839: A pH between 5.7 and 7.2. Major pests of the watermelon include aphids , fruit flies , and root-knot nematodes . In conditions of high humidity, the plants are prone to plant diseases such as powdery mildew and mosaic virus . Some varieties often grown in Japan and other parts of the Far East are susceptible to fusarium wilt . Grafting such varieties onto disease-resistant rootstocks offers protection. The US Department of Agriculture recommends using at least one beehive per acre (4,000 m per hive) for pollination of conventional, seeded varieties for commercial plantings. Seedless hybrids have sterile pollen. This requires planting pollinizer rows of varieties with viable pollen. Since

860-449: A predator as a last resort. About 25 species are rated by the IUCN as endangered , such as the dama gazelle and mountain nyala . A number of subspecies are also endangered, including the giant sable antelope and the mhorr gazelle . The main causes for concern for these species are habitat loss, competition with cattle for grazing, and trophy hunting. The chiru or Tibetan antelope

946-940: A prehistoric archaeological site located in southwestern Libya . This archaeobotanical discovery may support the possibility that the plant was more widely distributed in the past. In the 7th century , watermelons were being cultivated in India, and by the 10th century had reached China. The Moors introduced the fruit into the Iberian Peninsula , and there is evidence of it being cultivated in Córdoba in 961 and also in Seville in 1158. It spread northwards through southern Europe , perhaps limited in its advance by summer temperatures being insufficient for good yields. The fruit had begun appearing in European herbals by 1600, and

1032-622: A single breeding male, which excludes all other males, often by combat. Antelope pursue a number of defense strategies, often dictated by their morphology. Large antelope that gather in large herds, such as wildebeest, rely on numbers and running speed for protection. In some species, adults will encircle the offspring, protecting them from predators when threatened. Many forest antelope rely on cryptic coloring and good hearing to avoid predators. Forest antelope often have very large ears and dark or striped colorations. Small antelope, especially duikers , evade predation by jumping into dense bush where

1118-438: A thick, persistent sheath of horny material , both of which distinguish them from antlers. Antelope horns are efficient weapons, and tend to be better developed in those species where males fight over females (large herd antelope) than in solitary or lekking species. With male-male competition for mates, horns are clashed in combat. Males more commonly use their horns against each other than against another species. The boss of

1204-428: A variety with sweet yellow flesh that is cultivated around the world for fodder and the production of citron peel and pectin . (syn. C. lanatus var. caffer ) C. caffer Schrad. is a synonym of C. amarus Schrad. The variety known as tsamma is grown for its juicy white flesh. The variety was an important food source for travellers in the Kalahari Desert . Another variety known as karkoer or bitterboela

1290-647: A wide geographical area. It produced high yields and was resistant to the most serious watermelon diseases: anthracnose and fusarium wilt . Others were also working on disease-resistant cultivars; J. M. Crall at the University of Florida produced 'Jubilee' in 1963 and C. V. Hall of Kansas State University produced 'Crimson Sweet' the following year. These are no longer grown to any great extent, but their lineage has been further developed into hybrid varieties with higher yields, better flesh quality and attractive appearance. Another objective of plant breeders has been

1376-510: A wide range of habitats. Most live in the African savannahs . However, many species are more secluded, such as the forest antelope, as well as the extreme cold-living saiga , the desert-adapted Arabian oryx , the rocky koppie -living klipspringer , and semiaquatic sitatunga . Species living in forests, woodland, or bush tend to be sedentary, but many of the plains species undertake long migrations. These enable grass-eating species to follow

1462-469: Is monoecious . The male flowers predominate at the beginning of the season; the female flowers, which develop later, have inferior ovaries. The styles are united into a single column. The large fruit is a kind of modified berry called a pepo with a thick rind ( exocarp ) and fleshy center ( mesocarp and endocarp). Wild plants have fruits up to 20 cm (8 in) in diameter, while cultivated varieties may exceed 60 cm (24 in). The rind of

1548-611: Is also present in the Chihuahuan Desert where they are problematic for the local ecosystem. Gemsbok live in herds of about 10–40 animals, which consist of a dominant male , a few nondominant males, and females. They are mainly desert -dwelling and do not depend on drinking water to supply their physiological needs. They can reach running speeds of up to 60 km/h (37 mph). Gemsbok are mostly crepuscular in nature, since temperatures are tolerable and predator detection rates are highest during these times. The gemsbok

1634-447: Is densely woolly with yellowish-brown hairs which disappear as the plant ages. Like all but one species in the genus Citrullus , watermelon has branching tendrils . Plants have unisexual male or female flowers that are white or yellow and borne on 40-millimetre-long ( 1 + 1 ⁄ 2  in) hairy stalks. Each flower grows singly in the leaf axils, and the species' sexual system , with male and female flowers produced on each plant,

1720-769: Is derived from the Old French antelop , itself derived from Medieval Latin ant(h)alopus , which in turn comes from the Byzantine Greek word ἀνθόλοψ, anthólops , first attested in Eustathius of Antioch ( c.  336 ), according to whom it was a fabulous animal "haunting the banks of the Euphrates, very savage, hard to catch and having long, saw-like horns capable of cutting down trees". It perhaps derives from Greek ἀνθος, anthos (flower) and ώψ, ops (eye), perhaps meaning "beautiful eye" or alluding to

1806-616: Is found on the continent—the Barbary red deer of Northern Africa. By comparison, numerous deer species are usually found in regions of the world with fewer or no antelope species present, such as throughout Southeast Asia , Europe and all of the Americas . This is likely due to competition over shared resources, as deer and antelope fill a virtually identical ecological niche in their respective habitats. Countries like India, however, have large populations of endemic deer and antelope, with

1892-404: Is generally a grazer but changes to browsing during the dry season or when grass is sparse. It may dig up to a meter deep to find roots and tubers, supplementing its water intake by eating wild tsamma melons and cucumbers , which can provide all the water required (3 liters per 100 kg bodyweight a day). The gemsbok is polygynous , with one resident male mating with the receptive females in

1978-432: Is grown in favorable climates from tropical to temperate regions worldwide for its large edible fruit , which is a berry with a hard rind and no internal divisions, and is botanically called a pepo . The sweet, juicy flesh is usually deep red to pink, with many black seeds, although seedless varieties exist. The fruit can be eaten raw or pickled , and the rind is edible after cooking. It may also be consumed as

2064-425: Is hunted for its pelt, which is used in making shahtoosh wool, used in shawls. Since the fur can only be removed from dead animals, and each animal yields very little of the downy fur, several antelope must be killed to make a single shawl. This unsustainable demand has led to enormous declines in the chiru population. The saiga is hunted for its horns, which are considered an aphrodisiac by some cultures. Only

2150-612: Is prized for supposed medicinal and magical powers in many places. The horn of the male saiga, in Eastern practice, is ground as an aphrodisiac, for which it has been hunted nearly to extinction. In the Congo , it is thought to confine spirits. The antelope's ability to run swiftly has also led to their association with the wind , such as in the Rig Veda , as the steeds of the Maruts and

2236-500: Is produced in watermelon rind . A number of cultivar groups have been identified: (syn. C. lanatus subsp. lanatus var. citroides ; C. lanatus var. citroides ; C. vulgaris var. citroides ) DNA data reveal that C. lanatus var. citroides Bailey is the same as Thunberg's bitter wooly melon, C. lanatus and also the same as C. amarus Schrad. It is not a form of the sweet watermelon C. vulgaris nor closely related to that species. The citron melon or makataan –

2322-417: Is some variation of a brown colour (or several shades of brown), often with white or pale underbodies. Exceptions include the zebra-marked zebra duiker , the grey, black, and white Jentink's duiker , and the black lechwe . Most of the "spiral-horned" antelope have pale, vertical stripes on their backs. Many desert and semidesert species are particularly pale, some almost silvery or whitish (e.g. Arabian oryx);

2408-459: Is still a matter of debate, with several alternative systems proposed. Antelope are not a cladistic or taxonomically defined group. The term is used to describe all members of the family Bovidae that do not fall under the category of sheep , cattle , or goats . Usually, all species of the Antilopinae , Hippotraginae , Reduncinae , Cephalophinae , many Bovinae , the grey rhebok , and

2494-574: Is the "golden oryx", in which the gemsbok's black markings are muted and appear to be golden. Gemsbok are the largest species in the genus Oryx . They stand about 1.2 m (4 ft) at the shoulder. The body length can vary from 190 to 240 cm (75 to 94 in) and the tail measures 45 to 90 cm (18 to 35 in). Male gemsbok can weigh between 180 and 240 kg (400 and 530 lb), while females weigh 100–210 kg (220–460 lb). Gemsbok are widely hunted for their spectacular horns that average 85 cm (33 in) in length. From

2580-697: Is unpalatable to humans, but the seeds may be eaten. A small-fruited form with a bumpy skin has caused poisoning in sheep. This is Linnaeus's sweet watermelon; it has been grown for human consumption for thousands of years. This West African species is the closest wild relative of the watermelon. It is cultivated for cattle feed. Additionally, other wild species have bitter fruit containing cucurbitacin . C. colocynthis (L.) Schrad. ex Eckl. & Zeyh., C. rehmii De Winter, and C. naudinianus (Sond.) Hook.f. The more than 1,200 cultivars of watermelon range in weight from less than 1 kilogram ( 2 + 1 ⁄ 4 pounds) to more than 90 kg (200 lb);

2666-584: The Americas , though the nominate saiga subspecies occurred in North America during the Pleistocene. North America is currently home to the native pronghorn , which taxonomists do not consider a member of the antelope group, but which is often locally referred to as such (e.g., "American antelope"). In Europe , several extinct species occur in the fossil record, and the saiga was found widely during

2752-853: The Pleistocene but did not persist into the later Holocene , except in Russian Kalmykia and Astrakhan Oblast . Many species of antelope have been imported to other parts of the world, especially the United States, for exotic game hunting. With some species possessing spectacular leaping and evasive skills, individuals may escape. Texas in particular has many game ranches, as well as habitats and climates that are very hospitable to African and Asian plains antelope species. Accordingly, wild populations of blackbuck antelope, gemsbok , and nilgai may be found in Texas. Antelope live in

2838-399: The beisa and southern oryxes have gray and black pelages with vivid black-and-white faces. Common features of various gazelles are white rumps, which flash a warning to others when they run from danger, and dark stripes midbody (the latter feature is also shared by the springbok and beira). The springbok also has a pouch of white, brushlike hairs running along its back, which opens up when

2924-428: The elands . These antelope sometimes jump over each other's backs when alarmed, but this incongruous talent seems to be exploited only by wild members of the species; tame elands do not take advantage of it and can be enclosed within a very low fence. Their meat, milk, and hides are all of excellent quality, and experimental eland husbandry has been going on for some years in both Ukraine and Zimbabwe. In both locations,

3010-503: The impala are called antelope. More species of antelope are native to Africa than to any other continent, almost exclusively in savannahs , with 25-40 species co-occurring over much of East Africa. Because savannah habitat in Africa has expanded and contracted five times over the last three million years, and the fossil record indicates this is when most extant species evolved, it is believed that isolation in refugia during contractions

3096-414: The pronghorn ( Antilocapra americana ) and the mule deer ( Odocoileus hemionus ). In addition, gemsbok may spread disease to fellow bovids like the desert bighorn sheep ( Ovis canadensis nelsoni ). The gemsbok is depicted on the coat of arms of Namibia , where the current population of the species is estimated at 373,000 individuals. In the town of Oranjemund , resident gemsbok wander freely around

3182-472: The "American antelope", despite the fact that it belongs to a completely different family ( Antilocapridae ) than the true Old-World antelopes; pronghorn are the sole extant member of an extinct prehistoric lineage that once included many unique species. Although antelope are sometimes referred to, and easily misidentified as, "deer" ( cervids ), true deer are only distantly related to antelope. While antelope are found in abundance in Africa, only one deer species

3268-471: The 21st century, rising to nearly 85% of total watermelon sales in the United States in 2014. A melon from the Kordofan region of Sudan – the kordofan melon – may be the progenitor of the modern, domesticated watermelon. The kordofan melon shares with the domestic watermelon loss of the bitterness gene while maintaining a sweet taste, unlike other wild African varieties from other regions, indicating

3354-616: The abolition of slavery. After the Civil War, black people were maligned for their association with watermelon. The sentiment evolved into a racist stereotype where black people shared a supposed voracious appetite for watermelon, a fruit long associated with laziness and uncleanliness. Seedless watermelons were initially developed in 1939 by Japanese scientists who were able to create seedless triploid hybrids which remained rare initially because they did not have sufficient disease resistance . Seedless watermelons became more popular in

3440-476: The animal has proved wholly amenable to domestication. Similarly, European visitors to Arabia reported "tame gazelles are very common in the Asiatic countries of which the species is a native; and the poetry of these countries abounds in allusions both to the beauty and the gentleness of the gazelle." Other antelope that have been tamed successfully include the gemsbok , the kudu , and the springbok . Nor are

3526-503: The animal senses danger, causing the dorsal hairs to stand on end. Many antelope are sexually dimorphic. In most species, both sexes have horns, but those of males tend to be larger. Males tend to be larger than the females, but exceptions in which the females tend to be heavier than the males include the bush duiker , dwarf antelope , Cape grysbok , and oribi , all rather small species. A number of species have hornless females (e.g., sitatunga , red lechwe , and suni ). In some species,

3612-421: The animal that antelope do not typically display. Most species are difficult to contain in any density, due to the territoriality of the males, or in the case of oryxes (which have a relatively hierarchical social structure), an aggressive disposition; they can easily kill a human. Because many have extremely good jumping abilities, providing adequate fencing is a challenge. Also, antelope will consistently display

3698-505: The animals' long eyelashes. This, however, may be a folk etymology in Greek based on some earlier root. The word talopus and calopus , from Latin, came to be used in heraldry . In 1607, it was first used for living, cervine animals . There are 91 antelope species, most of which are native to Africa, occur in about 30 genera. The classification of tribes or subfamilies within Bovoidea

3784-657: The bitter wooly melon Citrullus lanatus (Thunb.) Matsum. & Nakai are not closely related to each other. A proposal to conserve the name, Citrullus lanatus (Thunb.) Matsum. & Nakai, was accepted by the nomenclature committee and confirmed at the International Botanical Congress in 2017. Prior to 2015, the wild species closest to Citrullus lanatus was assumed to be the tendril-less melon Citrullus ecirrhosus Cogn. from South African arid regions based on an erroneously identified 18th-century specimen. However, after phylogenetic analysis,

3870-540: The characteristics described above necessarily barriers to domestication; for further information, see animal domestication . A wide variety of antelope hybrids have been recorded in zoos, game parks, and wildlife ranches, due to either a lack of more appropriate mates in enclosures shared with other species or a misidentification of species. The ease of hybridization shows how closely related some antelope species are. With few exceptions, most hybrid antelope occur only in captivity. Most hybrids occur between species within

3956-413: The closest relative to Citrullus lanatus is now thought to be Citrullus mucosospermus (Fursa) from West Africa (from Senegal to Nigeria), which is also sometimes considered a subspecies within C. lanatus . Watermelon populations from Sudan are also close to domesticated watermelons. The bitter wooly melon was formally described by Carl Peter Thunberg in 1794 and given the name Momordica lanata . It

4042-421: The different species generally keeping to their own "niches" with minimal overlap. Unlike deer, in which the males sport elaborate head antlers that are shed and regrown annually, antelope horns are bone and grow steadily, never falling off. If a horn is broken, it will either remain broken or take years to partially regenerate, depending on the species. The English word "antelope" first appeared in 1417 and

4128-448: The duikers and dwarf antelope tend to be simple "spikes", but differ in the angle to the head from backward curved and backward pointing (e.g. yellow-backed duiker ) to straight and upright (e.g. steenbok ). Other groups have twisted (e.g. common eland ), spiral (e.g. greater kudu ), "recurved" (e.g. the reedbucks ), lyrate (e.g. impala ), or long, curved (e.g. the oryxes ) horns. Horns are not shed and their bony cores are covered with

4214-402: The edible var. vulgaris may be the most important. This taxonomy originated with the erroneous synonymization of the wooly melon Citrullus lanatus with the sweet watermelon Citrullus vulgaris by L.H. Bailey in 1930. Molecular data, including sequences from the original collection of Thunberg and other relevant type material, show that the sweet watermelon ( Citrullus vulgaris Schrad.) and

4300-411: The elimination of the seeds which occur scattered throughout the flesh. This has been achieved through the use of triploid varieties, but these are sterile, and the cost of producing the seed by crossing a tetraploid parent with a normal diploid parent is high. As of 2017, farmers in approximately 44 states in the United States grew watermelon commercially, producing more than $ 500 million worth of

4386-519: The end of its snout. This bizarre and inaccurate form was invented by European heralds in the Middle Ages, who knew little of foreign animals and made up the rest. The antelope was mistakenly imagined to be a monstrous beast of prey; the 16th century poet Edmund Spenser referred to it as being "as fierce and fell as a wolf ." Antelope can all also occur in their natural form, in which case they are termed "natural antelope" to distinguish them from

4472-475: The facial pattern) are noticed, the chamois and the oryx are not closely related. The usual pronunciation in English is / ˈ ɡ ɛ m z b ɒ k / . Gemsbok are light taupe to tan in color, with lighter patches toward the bottom rear of the rump. Their tails are long and black in color. A blackish stripe extends from the chin down the lower edge of the neck, through the juncture of the shoulder and leg along

4558-618: The few antelope species where female trophies are sometimes more desirable than male ones. A gemsbok horn can be fashioned into a natural trumpet and, according to some authorities, can be used as a shofar . Gemsbok are found in arid and semi-arid bushlands in southwestern Africa, especially around the Namib and Kalahari deserts, in Botswana , Zimbabwe , Namibia , South Africa and formerly Angola (where they are considered extirpated ). A sizeable introduced population of several thousand

4644-561: The flesh can be red, pink, orange, yellow or white. Charles Fredrick Andrus, a horticulturist at the USDA Vegetable Breeding Laboratory in Charleston, South Carolina , set out to produce a disease-resistant and wilt-resistant watermelon. The result, in 1954, was "that gray melon from Charleston". Its oblong shape and hard rind made it easy to stack and ship. Its adaptability meant it could be grown over

4730-531: The flesh of the watermelon to develop a large hole, sometimes in an intricate, symmetric shape. Watermelons suffering from hollow heart are safe to consume. Farmers of the Zentsuji region of Japan found a way to grow cubic watermelons by growing the fruits in metal and glass boxes and making them assume the shape of the receptacle. The cubic shape was originally designed to make the melons easier to stack and store, but these " square watermelons " may be triple

4816-421: The fruit annually. Georgia, Florida, Texas, California and Arizona are the United States' largest watermelon producers, with Florida producing more watermelon than any other state. This now-common fruit is often large enough that groceries often sell half or quarter melons. Some smaller, spherical varieties of watermelon—both red- and yellow-fleshed—are sometimes called "icebox melons". The largest recorded fruit

4902-438: The fruit is mid- to dark green and usually mottled or striped, and the flesh, containing numerous pips spread throughout the inside, can be red or pink (most commonly), orange, yellow, green or white. A bitter watermelon, C. amarus , has become naturalized in semiarid regions of several continents, and is designated as a "pest plant" in parts of Western Australia where they are called "pig melon". The sweet watermelon

4988-727: The herd. The calf is weaned at 3 + 1 ⁄ 2 months, becomes independent at 4 + 1 ⁄ 2 months, and achieves sexual maturity at 1 + 1 ⁄ 2 –2 years in both sexes. In 1969, the New Mexico State Department of Game and Fish decided to introduce gemsbok to the Tularosa Basin , New Mexico , in the United States . Ninety-three were released from 1969 to 1977, with the current population estimated to be around 3,000 individuals. Gradually expanding their range from Tularosa Basin towards

5074-508: The herd. The male is known to secure exclusive mating access to the females by attempting to herd mixed or nursery herds onto his territory. The gemsbok has no specified breeding season, but the young in a given herd tend to be of a similar age due to reproductive synchrony between females. Pregnant females leave the herd before giving birth. The gestation period lasts 270 days and mothers give birth to 1–2 offspring. The calf remains hidden 6 weeks after birth, after which mother and calf rejoin

5160-465: The horns is typically arranged in such a way that two antelope striking at each other's horns cannot crack each other's skulls, making a fight via horn more ritualized than dangerous. Many species have ridges in their horns for at least two-thirds the length of their horns, but these ridges are not a direct indicator of age. Antelope are often classified by their reproductive behavior. Small antelope, such as dik-diks , tend to be monogamous. They live in

5246-494: The lower flank of each side to the blackish section of the rear leg. They have muscular necks and shoulders, and their legs have white 'socks' with a black patch on the front of both the front legs, and both sexes have long, straight horns. Comparably, the East African oryx lacks a dark patch at the base of the tail, has less black on the legs (none on the hindlegs), and less black on the lower flanks. One very rare color morph

#1732801840073

5332-486: The males and females have differently coloured pelages (e.g. blackbuck and nyala ). Antelope are ruminants , so they have well-developed molar teeth , which grind cud (food balls stored in the stomach) into a pulp for further digestion. They have no upper incisors, but rather a hard upper gum pad, against which their lower incisors bite to tear grass stems and leaves. Like many other herbivores , antelope rely on keen senses to avoid predators. Their eyes are placed on

5418-542: The males have horns, and have been so heavily hunted that some herds contain up to 800 females to one male. The species has shown a steep decline and is critically endangered. It is difficult to determine how long antelope live in the wild. With the preference of predators towards old and infirm individuals, which can no longer sustain peak speeds, few wild prey-animals live as long as their biological potential. In captivity, wildebeest have lived beyond 20 years old, and impalas have reached their late teens. The antelope's horn

5504-564: The more usual heraldic antelope. The arms previously used by the Republic of South Africa featured a natural antelope, along with an oryx . Citrullus lanatus Watermelon ( Citrullus lanatus ) is a flowering plant species of the Cucurbitaceae family and the name of its edible fruit . A scrambling and trailing vine -like plant, it is a highly cultivated fruit worldwide, with more than 1,000 varieties . Watermelon

5590-429: The outside, red on the inside'. In the United States, it has also been used as a racist stereotype associated with African Americans . Watermelons are plants grown from tropical to temperate climates, needing temperatures higher than about 25 °C (77 °F) to thrive. On a garden scale, seeds are usually sown in pots under cover and transplanted into the ground. Ideal conditions are a well-drained sandy loam with

5676-476: The predator cannot pursue. Springboks use a behavior known as stotting to confuse predators. Open grassland species have nowhere to hide from predators, so they tend to be fast runners. They are agile and have good endurance —these are advantages when pursued by sprint-dependent predators such as cheetahs , which are the fastest of land animals, but tire quickly. Reaction distances vary with predator species and behaviour. For example, gazelles may not flee from

5762-611: The price of normal ones, so appeal mainly to wealthy urban consumers. Pyramid-shaped watermelons have also been developed, and any polyhedral shape may potentially be used. Watermelons, which are called tsamma in Khoisan language and makataan in Tswana language , are important water sources in South Africa , the Kalahari Desert , and East Africa for both humans and animals. In 2020, global production of watermelons

5848-431: The rains and thereby their food supply. The gnus and gazelles of East Africa perform some of the most impressive mass migratory circuits of all mammals. Antelope vary greatly in size. For example, a male common eland can measure 178 cm (5 ft 10 in) at the shoulder and weigh almost 950 kg (2,100 lb), whereas an adult royal antelope may stand only 24 cm ( 9 + 1 ⁄ 2  in) at

5934-462: The related East African oryx , or beisa oryx ( Oryx beisa ), as a subspecies . The name gemsbok is from Afrikaans , which itself is from the Dutch word of the same spelling, meaning "male chamois ", composed of gems (“chamois”) + bok (“buck, male goat”). The Dutch gems is further from German Gämse ("chamois"). Although some superficial similarities in appearance (especially in

6020-403: The same genus. All reported examples occur within the same subfamily. As with most mammal hybrids, the less closely related the parents, the more likely the offspring will be sterile. Antelope are a common symbol in heraldry , though they occur in a highly distorted form from nature. The heraldic antelope has the body of a stag and the tail of a lion , with serrated horns, and a small tusk at

6106-415: The shadows rapidly. Gazelle and springbok are known for their speed and leaping abilities. Even larger antelope, such as nilgai, elands , and kudus , are capable of jumping 2.4 m (7 ft 10 in) or greater, although their running speed is restricted by their greater mass. Antelope have a wide variety of coverings, though most have a dense coat of short fur. In most species, the coat (pelage)

6192-552: The shoulder and weigh a mere 1.5 kg ( 3 + 1 ⁄ 4  lb). Not surprisingly for animals with long, slender yet powerful legs, many antelope have long strides and can run fast. Some (e.g. klipspringer) are also adapted to inhabiting rock koppies and crags. Both dibatags and gerenuks habitually stand on their two hind legs to reach acacia and other tree foliage. Different antelope have different body types, which can affect movement. Duikers are short, bush-dwelling antelope that can pick through dense foliage and dive into

6278-806: The sides of their heads, giving them a broad radius of vision with minimal binocular vision. Their horizontally elongated pupils also help in this respect. Acute senses of smell and hearing give antelope the ability to perceive danger at night out in the open (when predators are often on the prowl). These same senses play an important role in contact between individuals of the same species; markings on their heads, ears, legs, and rumps are used in such communication. Many species "flash" such markings, as well as their tails; vocal communications include loud barks, whistles, "moos", and trumpeting; many species also use scent marking to define their territories or simply to maintain contact with their relatives and neighbors. The size and shape of antelope horns varies greatly. Those of

6364-919: The state, and the reintroduced Mexican wolf ( Canis lupus baileyi ) is too low in population numbers (and all known Mexican wolf populations are over 100 miles away). The species is therefore primarily managed by regulated hunting. However, the only North American predator that regularly takes gemsbok is the cougar ( Puma concolor ); for only one individual, 29 gemsbok were hunted, with the species making up 58% of recorded kills (most consisting of newborns, but some adults were also known to have been killed). Additionally, New Mexico gemsbok seem to prefer undisturbed grasslands for feeding, putting pressure on grassland ecosystems already threatened by climate change and encroachment by shrubs. This fact, along with their larger size and potentially dangerous horns, may cause them to outcompete with and/or put pressure on not only local livestock operations, but native desert herbivores, such as

6450-414: The streets, taking advantage of the vegetation in the town, such as the grass in parks, road medians, and browsing on low branches of the many trees. Antelope A better definition, also known as the "true antelopes", includes only the genera Gazella , Nanger , Eudorcas , and Antilope . One North American mammal, the pronghorn or "pronghorn antelope", is colloquially referred to as

6536-440: The supply of viable pollen is reduced, and pollination is much more critical in producing the seedless variety, the recommended number of hives per acre increases to three hives per acre ( 1,300 m per hive). Watermelons have a longer growing period than other melons and can often take 85 days or more from the time of transplanting for the fruit to mature. Lack of pollen is thought to contribute to "hollow heart" which causes

6622-805: The sweet modern variety. Sweet dessert watermelons spread across the Mediterranean world during Roman times . Considerable breeding effort has developed disease-resistant varieties. Many cultivars are available that produce mature fruit within 100 days of planting. In 2017, China produced about two-thirds of the world's total of watermelons. The watermelon is an annual that has a prostrate or climbing habit. Stems are up to 3 metres (10 feet) long and new growth has yellow or brown hairs. Leaves are 60 to 200 millimetres ( 2 + 1 ⁄ 4 to 7 + 3 ⁄ 4 inches) long and 40 to 150 mm ( 1 + 1 ⁄ 2 to 6 in) wide. These usually have three lobes that are lobed or doubly lobed. Young growth

6708-423: The transplanted population thrives in the absence of their natural predators, such as the lion ( Panthera leo ), spotted hyena ( Crocuta crocuta ), cheetah ( Acinonyx jubatus ) and leopard ( Panthera pardus ). Except for calves, the oryx is too large to be preyed on by the coyote ( Canis latrans ) and most other major American desert carnivores, since the jaguar ( Panthera onca ) is mostly extirpated from

6794-735: The west and northwest, an unknown number of animals are now also established in the San Andres National Wildlife Refuge , the Jornada Biosphere Reserve as well as the endorheic drainage basins east of Caballo Mountains , especially where these are traversed by the Jornada del Muerto trail north of Upham . The inherent biology of gemsbok makes them a potential invasive species in New Mexico. As they are capable of year-round breeding,

6880-413: The wind god Vayu . There is, however, no scientific evidence that the horns of any antelope have any change on a human's physiology or characteristics. In Mali, antelope were believed to have brought the skills of agriculture to mankind. Humans have also used the term "Antelope" to refer to a tradition usually found in the sport of track and field. Domestication of animals requires certain traits in

6966-655: Was a major driver of this diversification. Other species occur in Asia: the Arabian Peninsula is home to the Arabian oryx and Dorcas gazelle . South Asia is home to the nilgai , chinkara , blackbuck , Tibetan antelope , and four-horned antelope , while Russia and Central Asia have the Tibetan antelope and saiga . No antelope species is native to Australasia or Antarctica , nor do any extant species occur in

7052-825: Was being grown in Massachusetts by 1629, and by 1650 was being cultivated in Peru , Brazil and Panama . Around the same time, Native Americans were cultivating the crop in the Mississippi valley and Florida . Watermelons were rapidly accepted in Hawaii and other Pacific islands when they were introduced there by explorers such as Captain James Cook . In the Civil War era United States, watermelons were commonly grown by free black people and became one symbol for

7138-653: Was first described by Carl Linnaeus in 1753 and given the name Cucurbita citrullus . It was reassigned to the genus Citrullus in 1836, under the replacement name Citrullus vulgaris , by the German botanist Heinrich Adolf Schrader . (The International Code of Nomenclature for algae, fungi, and plants does not allow names like " Citrullus citrullus ".) The species is further divided into several varieties, of which bitter wooly melon ( Citrullus lanatus (Thunb.) Matsum. & Nakai var. lanatus ), citron melons ( Citrullus lanatus var. citroides (L. H. Bailey) Mansf.), and

7224-534: Was grown in Tennessee in 2013 and weighed 159 kilograms (351 pounds). Watermelon is a sweet, commonly consumed fruit of summer, usually as fresh slices, diced in mixed fruit salads , or as juice. Watermelon juice can be blended with other fruit juices or made into wine . The seeds have a nutty flavor and can be dried and roasted, or ground into flour. Watermelon rinds may be eaten, but their unappealing flavor may be overcome by pickling , sometimes eaten as

7310-580: Was reassigned to the genus Citrullus in 1916 by Japanese botanists Jinzō Matsumura and Takenoshin Nakai . Watermelons were originally cultivated for their high water content and stored to be eaten during dry seasons, as a source of both food and water. Watermelon seeds were found in the Dead Sea region at the ancient settlements of Bab edh-Dhra and Tel Arad . Many 5000-year-old wild watermelon seeds ( C. lanatus ) were discovered at Uan Muhuggiag ,

7396-594: Was widely planted in Europe in the 17th century as a minor garden crop. Early watermelons were not sweet, but bitter, with yellowish-white flesh. They were also difficult to open. The modern watermelon, which tastes sweeter and is easier to open, was developed over time through selective breeding . European colonists introduced the watermelon to the New World . Spanish settlers were growing it in Florida in 1576. It
