Interspecific hybridization between greater kudu and nyala ... differences.The former can disruptthe cascadeof events leadingto the developmentof testisand otherreproductive relatedoccurrences (see forexampleWaters and Robinson D.L. The Blue Wilderbeest is a large antelope which is to be found in the open plains, bushveld and dry woodlands of Southern and Eastern Africa. A shy animal, it prefers water holes rather than open spaces. According to a study, this can be attributed to the differences in their body sizes. Kudu migrate extensively through Kruger. The validity of the paper had to be called into question. It has been introduced to Botswana and Namibia, and reintroduced to Swaziland, where it had been extinct since the 1950s. These inhabit thickets within dense and dry savanna woodlands. They possess between 4 and 12 vertical white stripes along their torso. The Bushbuck is a close relative of the Kudu and the Nyala. Hybridization of wildlife species, even in the absence of introgression, is of concern due to wasted reproductive effort and a reduction in productivity. When two kudu bulls are equally matched a fight may ensue. Since there is such a big difference between the appearance of Nyala males and females, it is used as a divider between large and small antelope. [31], Another study was done to find whether the sexual dimorphism in the nyala influenced its foraging habits. Under normal circumstance, kudu will sneak away and hide from potential enemies. The lowland nyala or simply nyala (Tragelaphus angasii),[3] is a spiral-horned antelope native to southern Africa (not to be confused with the endangered Mountain nyala living in the Bale region of Ethiopia). The nyala is notable for its extreme gender differences (sexual dimorphism) and specialized habitat preferences Pronounced difference between females and adult males. [3], Nyala groups are according to sex or mixed. Kudu have many different behaviors and adaptations that help them survive. Males stand with erect posture, rub scent from face glands and make dung heaps to mark their territory. Their range averages 3 square miles and six to eight dominant males set up territories. They perform a high kick of the hind legs, a movement thought to release scent from the glands on the heels, making it easier for them to stay together or to confuse the predator. Nyala ewe's have … [2] Females and young males have ten or more white vertical stripes on their sides. Males are darker in color with far fewer white stripes, which are also less prominent. Adult males served hosts to more number of ticks and lice than adult females did. ; The kudu can jump six-foot-high fences from a standing position, and when fleeing from danger, they can clear obstacles as high as 10 feet. The male stands up to 110 cm (43 in), the female is up to 90 cm (3.0 ft) tall. [23] Also, a trypanosome was isolated from a nyala, wild-caught in Mozambique, which was diagnosed and found as akin to Trypanosoma vivax, based on biological, morphological and molecular data. Horns are 60–83 cm (24–33 in) long and yellow-tipped. [25], In a report published in 1994 entitled "Epidemiological observations on spongiform encephalopathies in captive wild animals in the British Isles" it was noted that spongiform encephalopathy (BSE) had been diagnosed in one nyala captive in a zoo. Horns are present in African Antelope species, such as Kudu, Impala, Eland and Wildebeest. In fact, you can tell the difference between an adult male and female just by looking at them – this is known as sexual dimorphism. Males are significantly larger and are covered with charcoal grey fur with the lower legs, ears and foreheads being tan. It was found that females spent equal periods of time foraging in all the three habitats, but males preferred sand forest more. They are greater than bushbucks but smaller than kudus. The Greater Kudu has a beard… Guest 16-Apr-2013 15:54: thanx a lot, now i know the differences between kudu,nyala and bushbuck [11][12], The nyala has 55 male chromosomes and 56 female chromosomes. The young males, however, are evicted from their mothers’ groups when they are 6 months old, staying around the edges of the herd until they join a bachelor group. On the other hand, the nuclear data shows that lesser kudu and nyala form a clade, and collectively separated from the sister clade 13.8 million years ago. [21], Another study of 97 blood samples of South African nyalas revealed the presence of tick-borne hemoparasites (blood parasites). The diet contained more proteins than fibers. Rams appear more charcoal grey in color. The Blue Wildebeest (also known as a Brindled Gnu) differs from the Black Wildebeest in both distribution and appearance. Formerly four subspecies have been described, but recently only one to three subspecies have been accepted based on colour, number of stripes and horn length: The physical attributes of the nyala differ between the males, known as bulls, and the females, known as cows. Males are slate grey to dark brown with up to 14 distinct white stripes across the back going down the flanks. The reverse occurred in the rainy season. The male grows to between 30 and 36 inches in height, while the female grows to between 28 and 32 inches. What is the difference between the Lesser Kudu and the Greater Kudu? In the wilderness areas and game reserves you spend time in during your programme antelope sightings will be a regular and there will be plenty of time to observe their behaviour. Males weigh 98–125 kg (220–280 lb), while females weigh 55–68 kg (120–150 lb). Really, in appearance, the mountain nyala is much more similar to the kudu (although they don't share the same habitat as the ibex and mountain nyala do) Birth takes place generally away from the sight of predators, in places such as a thicket. Medium-size antelope with vertical, white body stripes and a white band across base of neck. Other markings are visible on the face, throat, flanks and thighs. Pregnant females, both the antelopes nyala and impala, had higher KFIs than the non-pregnant ones. Size And Appearance. Females and young males have ten or more white stripes on their sides. [16] A study in Zululand showed that the nyala fed mainly in the early morning and the late afternoon. What is the difference between an Impala (Aepyceros melampus) and a Springbok (Antidorcas marsupialis)? The nyala is a spiral-horned antelope and is between a bushbuck and a kudu in size. [2] The nyala is typically between 135–195 cm (53–77 in) in head-and-body length. Some of the ways to tell the difference between nyala (pictured above) and kudu (pictured below) are: Nyala rams are shorter than kudu; Male nyala have more stripes and they are more pronounced against their darker and longer coats; Male kudu's have more pronounced humps; Kudu’s horns are longer, make a corkscrew spiral and don't have the yellow tip; Female kudu look more like males. Nyala characteristics. [7] but not widely recognized, and was only re-established as a valid genus in 2011 by Peter Grubb and Colin Groves. Ye :) I had about 50 pictures to go through that I had temporary put in a folder for "Nyala", and when I started to study them I noticed that at least ten of them were Kudu female pictures...But it helps to upload spottings, and now I am a bit better to identify the main differences between them, and I hope to be able to name the species next time I see them in their habitat. The Bushbuck is a close relative of the Kudu and the Nyala. On landing, they open up the throttle and can easily escape most predators. The greater kudu is considered by many to be the most handsome of the tragelaphine antelopes, which includes the bongo, eland, nyala, bushbuck and sitatunga. Necrosis (that is, the premature death of cells in a living tissue) and mineralization were found in the skeletal muscle after a histological analysis. As the rainy season arrived, both the species took to a diet of mainly monocotyledons, and the impala consumed more of them. That’s why an impala is an antelope, but not a gazelle. It chooses places with good quality grasslands as well as provision of fresh water. Only males have horns, 60–83 cm (24–33 in) long and yellow-tipped. These are the Ndumo Game Reserve, uMkuze Game Reserve and Hluhluwe-Umfolozi Game Reserve and Kruger National Park. Nyala; Greater Kudu; Resources; Contact; Nyala Description. BibTex; Full citation; Publisher: Springer Nature. [26] The nyala was formerly affected by the disease rinderpest, although the viral disease is considered eradicated now. Female nyala are known to reach sexual maturity at 11-12 months (one year), the male nyala reaching the sexual maturity at 18 months. They mostly occur in South Africa due to the high demand for adult males as game trophies. However, they are adapted to live in areas with only a seasonal availability of water. During the rainy season they feed upon the fresh grass. In height they are 700mm at the shoulders, and have a maximum mass of 54 Kg's. The hybrid was phenotypically nyala and was identified as such based on mitochondrial DNA. Another interesting fact about Nyala while we discuss male/females is the naming of the two genders. [6], The nyala is the second taxon to branch off from the tragelaphine family tree just after the lesser kudu. Ewes are smaller and adult ewes are lighter in colour than rams, with more pronounced white spots and stripes. Populations vary from 2-3 animals per square kilometer. The reason for this is still unknown, but attributed to the photoperiod and the feeding habits of the animal. The difference between a male and female nyala. This is another tricky one so we thought we would try shed some light on how to tell them apart. These antelopes rest in thick bushes during the hot hours of the day. mtDNA and nDNA data were compared. For other uses, see, Alden, P. C.; Estes, R. D.; Schlitter, D.; McBride, B. [34], Before ovulation, the Graafian follicles reach a length of at least 6.7 cm (2.6 in). After a gestational period of seven months, a single calf is born. Nyala Lesser kudu Phylogenetic ... An accidental mating between a male giant eland and a female kudu produced a male offspring, but it was azoospermic. During this transition period they are most vulnerable to predators. This variety in their diet is one of the factors ensuring their successful survival. They have vertical bands of dark brown hair on their bodies, which makes them look wrinkled. When alerted by a predator they move slowly before leaping vertically in the air. In this study we detail an accidental mating between a female nyala (Tragelaphus angasii) and a male greater kudu (T. strepsiceros). Due to their difference in size a nyala bull will eat twice as much as a female. [27] Generally adult males remain alone. [15] Each group consists of two to ten individuals. Males weigh 98-125 kg and stand over one meter tall at the shoulder, while females weigh 55-68 kg and are slightly less than a meter tall. Ostertagia harrisi and C. rotundispiculum were the most dominant nematodes in the antelope. According to statistics of 1999, 10-15% of the nyala occur on private land. As the nyala line has remained separate for a considerable amount of time (over 5 million years), it has now been placed in its own monotypic genus Nyala. Kudu migrate extensively through Kruger. Physical Characteristics Kudus, both the greater kudu and its close cousin the lesser kudu, have stripes and spots on the body, and most have a chevron of white hair on the forehead between the eyes. Secondly, in most species of gazelles both male and female animals have horns. [13] The Y chromosome has been translocated onto the 14th chromosome, as in other tragelaphids, but no inversion of the Y chromosome occurs. Analysis showed that it completely lacked germ cells, which produce gametes. Both sexes have a dorsal crest of hair running right from the back of the head to the end of the tail. What is the difference between a black and white rhino? The coat is maroon or rufous brown in females and juveniles, but grows a dark brown or slate grey, often tinged with blue, in adult males. Male Nyala are much larger and heavier than females. It is very secretive and more easily seen at night. There is a dark brown band separating this from the color of the body.There is a main of long hare running from the top of the head to the start of the tail.Females have a bright chestnut c… [3] The nyala's natural range stretches across southeast Africa from the Lower Shire Valley in Malawi through Mozambique and Zimbabwe to eastern South Africa and Swaziland. The graceful, elegant impala is prolific in South Africa's Kruger National Park and also in most other nature reserves in South Africa, Botswana, Zimbabwe, and Zambia. The Kudu, Eland and Oryx. Greater kudu have a wide repertoire of vocalizations, including barks, grunts, hooting bleats, and a whimper. The largest adult male Greaters stand over 5 ft. tall, and the largest male Lessers stand about 4 ft. tall. [22] Ten tick species, two louse species and a louse fly species were recovered in a study of 73 nyalas at Umfolozi, Mkuzi and Ndumu Game Reserves in northeastern KwaZulu-Natal in 1983 and 1984 and an additional six individuals in 1994.
