The situation was worse during World War II and other civil wars and political conflicts that harmed their natural habitats. These are game animals and are also hunted for trophies. The males weigh 400 to 1,000 kg (880 to 2,200 lb) and females weigh 300 to 600 kg (660 to 1,320 lb). Western Giant Eland Conservation. In the Bandia Reserve, differences in diet were marked among age classes. The giant eland is an herbivore, eating grasses, foliage and branches. The herd of Western giant eland in the Bandia reserve consists of (1,5) ani-mals original from the wild and (10,9,9) animals born in captivity (Fig. [39][40], Mating occurs throughout the year, but peaks in the wet season. No other change occurred in the farmed common eland calves, but in the giant eland calves, the males were found to suckle more than female ones and shorter suckling bouts were marked in primiparous mothers than multiparous ones. Image number. Giant elands are sometimes considered part of the genus Tragelaphus on the basis of molecular phylogenetics, but are usually categorized as Taurotragus, along with the common eland (T. oryx). [1], A study of the long-term conservation strategy of the western giant eland was done in the Bandia and Fathala reserves, using demographic and pedigree data based on continuous monitoring of reproduction during 2000 to 2009. [21], The smooth coat is reddish-brown to chestnut, usually darker in males than females, with 8–12 well-defined vertical white stripes on the torso. It is no longer present in The Gambia, Ghana, Ivory Coast, and Togo. [21][32], Many people prefer to tame and raise eland rather than cattle due to their numerous benefits. The authors concluded that with the introduction of new founders, the GD could be greatly improved in the next 100 years, and suggested that with proper management of the semi-captive population, the numbers of the western giant eland could be increased. Silvestre, I., Novelli, O., & Bogliani, G. (2000).

[48], Giant elands give large quantities of tender meat and high-quality hides even if fed a low-quality diet. Although the mean interbreeding level became 0.119, a potential gene diversity (GD) of 92% was retained. Content copyright © 2019 by Jeanne Egbosiuba Ukwendu. Rights Royalty Free Rights Managed. Critically endangered. Classified as “critically endangered” by the IUCN, the population of western giant elands (Tragelaphus derbianus derbianus) is estimated to include less than 200 individuals in the wild. The common eland and giant eland have been estimated to have diverged about 1.6 million years ago. Elands can survive on scarce water, which is a great advantage over domestic cattle. There are large black spots on the upper forelegs. [29], Previous genetic studies of African savanna ungulates revealed the presence of a long-standing Pleistocene refugium in eastern and southern Africa, which also includes the giant eland. As many other animals do, giant elands scrape mineral lick sites with the help of horns to loosen soil. Without effective protection in its last refuges in Senegal’s Niokolo-Koba National Park and an adjacent game reserve, the only hope for this subspecies’ survival is a captive breeding program. 148 likes. The giant eland (Taurotragus derbianus), also known as the Lord Derby eland, is an open-forest and savanna antelope. The giant eland is also parasitised by Carmyerius spatiosus (a trematode species), Taenia crocutae and T. hyaennae (two tapeworm species). Giant elands exhibit sexual dimorphism, as males are larger than females. [10][11][12], The giant eland was first described in 1847 by John Edward Gray, a British zoologist, who called it Boselaphus derbianus. Together with the bongo, Giant eland and common eland are the only antelopes in the tribe Tragelaphini to be given a generic name other than Tragelaphus. 5 Jul 2012 12:00 am. The study confirmed the presence of the chromosome translocation known as Robertsonian translocation (1;29), a widespread evolutionary marker common to all known tragelaphid species. The eastern giant eland is found in several reserves, for example in Bénoué National Park, Faro National Park and Bouba Njida National Park in Cameroon and in Manovo-Gounda St. Floris National Park in the Central African Republic. Create a free website Webnode [21] Adult males mainly remain alone,[23] and often spend time with females for an hour to a week. They form separate groups of males and of females and juveniles. Western Giant Eland (Tragelaphus / Taurotragus derbianus), the world's largest antelope. The lips are white, as are several dots along the jawline. 5164 – Western Giant Eland 38cmL. [17] Another study in Sudan showed that western giant elands preferred Cassia tora, which was the most abundant legume in the region. With more population, the elands were divided into five groups for observation. [8] The life expectancy of giant elands is up to 25 years in the wild, and about 20 years in captivity. It was due to his efforts that the giant eland was first introduced to England between 1835 and 1851. Today they are conserved in national parks and reserves, and occur mostly in Senegal. Captive. Giant Elands are not territorial, and have big home ranges. You might try using the wildcards * and ?
