– $24.95 Customer Service: Mon. See U.S. Patent 243688 - Bullard 1881. The tail (except the terminal black tuft), buttocks, the insides of the legs and the rump are all white. , Fossil springbok are known from the Pliocene; the antelope appears to have evolved about three million years ago from a gazelle-like ancestor. A springbok is an antelope found in southern Africa that gets its name from its remarkable jumping ability.  Eimeria species mainly affect juveniles. Aussie Rules Football A new combine record for the standing vertical jump was set at the 2016 AFL Draft Combine, then matched in 2017. The specific epithet marsupialis comes from the Latin marsupium ("pocket"); it refers to a pocket-like skin flap which extends along the midline of the back from the tail. Springbok meat may also be used in preparing salami; a study found that the flavour of this salami is better than mutton salami, and feels oilier than salami of beef, horse meat, or mutton. One can estimate how high a 'bok will jump (assuming it is made with a light, stiff spring) by using the following relationship: Be sure to select the ratio of the two masses so that the difference in the "jump height" for the two orientations of your 'bok (i.e., larger mass on top versus smaller mass on top) will be obvious. They are popular game animals, and are valued for their meat and skin. Model #2 attempts to improve upon Model 1 by taking into account the mass of the spring. , A study of vigilance behaviour of herds revealed that individuals on the borders of herds tend to be more cautious; vigilance decreases with group size. Both sexes reach 71–86 cm (28–34 in) at the shoulder with a head-and-body length typically between 120 and 150 cm (47 and 59 in). Answer. To make a springbok, simply attach two masses to opposite ends of a spring [Figure 1]. This woman found a springbok, you can clearly contemplate why the name contains the word spring in their name. Learn more. It is usually claimed that the best jumper in the world is the Flea. , The cap badge of The Royal Canadian Dragoons has featured a springbok since 1913, a reference to the unit's involvement in the Second Boer War. Two other varieties – pure black and pure white forms – are artificially selected in some South African ranches. Pronking – It wouldn’t be a Springbok without the “spring!” These antelope spring high into the air by bouncing up with all four feet, a behavior known and “pronking.” These animals can pronk over six feet in the air, and usually jump several times in a row. The forehead patch, dark brown or fawn, extends beyond the level of the eyes and mixes with the white of the face without any clear barriers. In extreme cases, they do not drink any water over the course of their lives. , Springbok are mainly active around dawn and dusk.  In 1999, Rod East of the IUCN SSC Antelope Specialist Group estimated the springbok population in South Africa at more than 670,000, noting that it might be an underestimate. What are the different kinds of Gazelles? Three subspecies are identified. Click on a link below to view a Quicktime video.  In fact, this physical feature distinguishes the springbok from true gazelles. , Springbok mate year-round, though females are more likely to enter oestrus during the rainy season, when food is more plentiful.  Although the exact cause of this behaviour is unknown, springbok exhibit this activity when they are nervous or otherwise excited.  It stands about 70 to 90 cm (28 to 35 in) high. A true pronker does these jumps continuously. Normally Springbok take off and jump run a bit, fall into a trot and curiosity wins.  In places such as Etosha National Park, springbok seek out water bodies where they are available. 4. Normally a single lamb is born (3) , after a 25 week gestation (2) , and is initially left hiding in a protected place, such as a bush, whilst the mother grazes away from her offspring. The object is to exchange the two sets of pegs. Fleas can jump 220 times their own body length and 150 times their own body height! What enables a springbok to jump so high? The sole member of the genus Antidorcas, this bovid was first described by the German zoologist Eberhard August Wilhelm von Zimmermann in 1780. They are widespread across Namibia and the vast grasslands of the Free State and the shrublands of Karoo in South Africa; however, they are confined to the Namib Desert in Angola. And they don’t just jump once.  These mass treks, known as trekbokking in Afrikaans, took place during long periods of drought. Now that we know how fast the frog is going when it leaves the ground, we can calculate the acceleration necessary to pro-duce this jump-the "pushing off the ground" part of Figure 3.43b. Average weight of males is 31 kg (68 lb), while for females it is 27 kg (60 lb).  Major differences in the size and weight of the subspecies are seen. The springbok (Antidorcas marsupialis) is a medium-sized antelope found mainly in southern and southwestern Africa. Male springbok (rams), engage in this behaviour in order to impress the females (ewes), showing off their ability to jump high into the air and display the hidden white fur, which releases a scented secretion from the inner glandular Sliding friction will decrease the performance of a 'bok, so you may wish to take steps to reduce it.  The meat may be consumed raw or used in prepared dishes. , Dark stripes extend across the white face, from the corner of the eyes to the mouth. The scientific name of the springbok is Antidorcas marsupialis. As for the long jump, at high speed the lion bounds in leaps of up to about 20 feet. When the mother gives birth again, the previous offspring, now 6 to 12 months old, deserts her to join herds of adult springbok. This model does not attempt to take into account sliding friction. Asked by Wiki User. Stotting (also called pronking or pronging) is a behavior of quadrupeds, particularly gazelles, in which they spring into the air, lifting all four feet off the ground simultaneously. Springbok is a type of antelope that belongs to the bovid family. Two conditions must hold for this assumption to be realized in practice: (1) the spring mass must be small compared to the attached masses and (2) the spring must be stiff. Their range extends from northwestern South Africa through the Kalahari desert into Namibia and Botswana. Springbok were found to be more cautious in the late morning than at dawn or in the afternoon, and more at night than in the daytime. A study tabulated average body measurements for the three subspecies. Females live with their offspring in herds, that very rarely include dominant males. After viewing, click your browser's "back" button to return here.  Stearic acid is the main fatty acid, accounting for 24–27% of the fatty acids. The springbok is characterised by a white face, a dark stripe running from the eyes to the mouth, a light-brown coat marked by a reddish-brown stripe that runs from the upper fore leg to the buttocks across the flanks like the Thomson's gazelle, and a white rump flap. It is in the same family as antelope and goats. In Marvels & Mysteries of Our Animal World, Jack Denton Scott is quoted as saying that tigers “can actually jump 18 feet straight up or … Champ Bailey, NFL 12-Time Pro-Bowler “I can run faster, jump higher, and have less fatigue. The Latin name Marsupialis refers to the pouch-like skin fold on …  Another study showed a strong correlation between the availability of winter dietary protein and the body mass. Be the first to answer! The springbok (Afrikaans and Dutch: spring = jump; bok = antelope or goat) (Antidorcas marsupialis) is a medium-sized brown and white gazelle of southwestern Africa. The springbok can survive under hot conditions without access of free water. A guide-pole and base are needed to maintain stable vertical motion [Figure 2]. Model #3 attempts to improve upon Model 1 by taking into account damping effects. In the other two subspecies, horns of both sexes are nearly similar. There are two other design issues to keep in mind when building a 'bok: Once a spring is selected, the only way to increase the jump height of the Springbok is to decrease its total mass. A. m. angolensis has a brown to tawny coat, with thick, dark brown stripes on the face extending two-thirds down to the snout. Active mainly at dawn and dusk, springbok form harems (mixed-sex herds).  They prefer grasses such as Themeda triandra.  The pH of the meat increases if the springbok is under stress or cropping is done improperly; consequently, the quality deteriorates and the colour darkens. However, A. m. marsupialis is the smallest subspecies; males are 75 cm (30 in) tall and females 72 cm (28 in) tall. Before proceeding to the rest of the web site, we suggest you try answering some basic questions about a springbok. Read More The medium brown forehead patch extends to eye level and is separated from the bright white face by a dark brown border.  The cladogram below is based on the 2013 study. The sole member of the genus Antidorcas, this bovid was first described by the German zoologist Eberhard August Wilhelm von Zimmermann in 1780. The speed when leaving the ground can be as high as 7 m/s. For our 'bok, which was made out of aluminum, we used a lacquer thinner to clean surfaces and graphite to lubricate them. "Helminth and arthropod parasites of springbok, "Arthropod parasites of springbok, gemsbok, kudus, giraffes and Burchell's and Hartmann's zebras in the Etosha and Hardap Nature Reserves, Namibia", "Energy, water, and food use by springbok antelope (. And they don’t just jump once. A single calf is born after a five- to six-month-long pregnancy; weaning occurs at nearly six months of age, and the calf leaves its mother a few months later.  Females are able to conceive at as early as six to seven months, whereas males do not attain sexual maturity until two years; rut lasts 5 to 21 days. It is around 9'9 feet but no one can jump that high in HighJump. It was adopted as a nickname or mascot by several South African sports teams, most famously by the national rugby union team. In 1972 Hendrine Pieterse won the South African women's High Jump title for the first and only time with the modest height of 1.72 metres, (which she later improved to 1.85m in other competition). Springbok inhabits open plains, grasslands, scrublands, deserts and semi-arid areas. It provides a rich context for exploring a wide range of physics concepts and principles, and it possesses a number of features that give it broad instructional value. The springbok is the national animal of South Africa. Free-body diagrams for the two masses and the springbok system are shown in the figure. The third species, A. recki, probably gave rise to the extant form A. marsupialis during the Pleistocene, about 100,000 years ago. Welcome to our collection of Springbok video clips. The equations of motion and solution for phase 2 are as follows (sorry for the ghastly color scheme --- it looked okay when we typeset it many years ago, for a much earlier web site with a different color scheme): The equations of motion and solution for phase 1 are as follows: In model 2 we assume that the spring has mass, but is always stretched uniformly. Good agreement with a simple Hooke's Law model requires a spring with a small damping coefficient. Some mammals that jump a lot, usually to hunt more and better or to escape their predators, are the the impala jumping up to 9 meters or 30 feet and the rabbit, that even though it is small in size can also jump up to 10 feet or 3 meters, which is pretty impressive for the furry budgie.  Springbok differ from gazelles in several other ways; for instance, springbok have two premolars on both sides of either jaw, rather than the three observed in gazelles. Springbok inhabit the dry areas of south and southwestern Africa.  In the mating season, males generally form herds and wander in search of mates. High jump animal champions. Springbok may accomplish this by selecting flowers, seeds, and leaves of shrubs before dawn, when the food items are most succulent. Hunting Springbok is all about shooting a pretty small animal at a far distance in a very short time. They generally tend to be ignored by carnivores unless they are breeding.  Springbok are generally quiet animals, though they may make occasional low-pitched bellows as a greeting and high-pitched snorts when alarmed.  The infant weighs 3.8 to 5 kg (8.4 to 11.0 lb); the female keeps her calf hidden in cover while she is away. It once roamed in In pronking, the springbok performs multiple leaps into the air in a stiff-legged posture, with the back bowed and the white flap lifted. Primarily a browser, the springbok feeds on shrubs and succulents; this antelope can live without drinking water for years, meeting its requirements through eating succulent vegetation. Group size and distance from roads and bushes were found to have major influence on vigilance, more among the grazing springbok than among their browsing counterparts.  When a female approaches a rutting male, the male holds his head and tail at level with the ground, lowers his horns, and makes a loud grunting noise to attract her. Although these assumptions are not completely satisfied by a real springbok, the model describes the qualitative features of the springbok's motion quite well. A peg can either move forward, or jump a peg in front of it (but neither is removed). There is much a student can learn about the physics of jumping from a purely conceptual analysis of this toy. The forehead is brown, fawn, or white, the patch not extending beyond the eyes and having no sharp boundaries. , The skin along the middle of the dorsal side is folded in, and covered with 15 to 20 cm (6 to 8 in) white hair erected by arrector pili muscles (located between hair follicles). The common name "springbok" comes from the Afrikaans words spring ("jump") and bok ("antelope" or "goat"); the first recorded use of the … Splitting Image Taxidermy offers hunters a turnkey solution to … (This is a companion website to the article Springbok: The physics of jumping, published in The Physics Teacher.). Southern African wildcats, black-backed jackals, black eagles, martial eagles, and tawny eagles target juveniles. That would be like us jumping nearly 400m in length whilst jumping over a 250m high building… Impressive! Ecology and physiology. Galagos can achieve a vertical jump height of 2.25m – remarkable for an animal little bigger than a rat ( ref.15 ). (The name "springbok" comes from a South African gazelle noted for its grace and its delightful habit of springing suddenly into the air.). , Springbok occur in several protected areas across their range: Makgadikgadi and Nxai National Park (Botswana); Kgalagadi Transfrontier Park between Botswana and South Africa; Etosha National Park and Namib-Naukluft Park (Namibia); Mokala and Karoo National Parks and a number of provincial reserves in South Africa.
