14-526: The Mitchell Grass Downs is a tropical and subtropical grasslands, savannas, and shrublands ecoregion in northeastern Australia . It is a mostly treeless grassland, characterised by Mitchell grasses ( Astrebla spp.). The ecoregion is bounded on the north and east by tropical savanna ecoregions – the Victoria Plains tropical savanna to the northeast, the Carpentaria tropical savanna to

28-586: A reasonable distance of water, and it also occurs in grasslands near rivers and lakes. Its habit of lying out in open grassland make it an accessible target for poachers , and 98% of the present population are found in national parks and other protected areas. Ugandan kobs are herbivores and feed largely on grasses and reeds. The females and young males form loose groups of varying size which range according to food availability, often moving along watercourses and grazing in valley bottoms. One group in South Sudan

42-870: Is tropical and semi-arid. Average annual rainfall varies across the ecoregion, from 350 mm to 750 mm. In much of the ecoregion rainfall is seasonal, coinciding with the summer monsoon. Rainfall becomes less seasonal towards the southeast. The vegetation consists mostly of grasses along with wildflowers and low shrubs, including Queensland bluebush ( Chenopodium auricomum ). There are scattered dry acacia woodlands, predominantly of gidgee ( Acacia cambagei ). Watercourses support woodlands of red river gum ( Eucalyptus camuldulensis ), coolibah ( E. coolabah ), and paperbark ( Melaleuca spp.). The Desert Uplands has dry woodlands of Eucalyptus populnea , E. melanophloia , and E. similis . Low open woodlands of snappy gum ( Eucalyptus leucophloia ), Cloncurry box ( E. leucophylla ), and silver box ( E. pruinosa ) grow in

56-596: Is usually unreliable. The rest of the year is cool and dry. Rainfall decreases as one goes either towards North in Northern Hemisphere or South in the Southern Hemisphere. Drought is very common. Tropical and subtropical grasslands, savannas, and shrublands occur on all continents but Antarctica. They are widespread in Africa , and are also found all throughout South Asia and Southeast Asia ,

70-421: The coat of arms of Uganda , along with a grey crowned crane ( Balearica regulorum gibbericeps ), representing the abundant wildlife present in the country. The Ugandan kob is similar in appearance to the impala but it is more sturdily built. Only the males have horns, which are lyre-shaped, strongly ridged and divergent. Males are slightly larger than females, being 90 to 100 cm (3.0 to 3.3 ft) at

84-638: The Mount Isa Inlier. Tropical and subtropical grasslands, savannas, and shrublands Grasslands are dominated by grasses and other herbaceous plants. Savannas are grasslands with scattered trees . Shrublands are dominated by woody or herbaceous shrubs. Large expanses of land in the tropics do not receive enough rainfall to support extensive tree cover. The tropical and subtropical grasslands, savannas, and shrublands are characterized by rainfall levels between 90–150 centimetres (35–59 in) per year. Rainfall can be highly seasonal, with

98-760: The ample forage typify the biodiversity associated with these habitats. These large mammal faunas are richest in African savannas and grasslands. The most intact assemblages currently occur in East African Acacia savannas and Zambezian savannas consisting of mosaics of miombo , mopane , and other habitats. Large-scale migration of tropical savanna herbivores, such as wildebeest ( Connochaetes taurinus ) and zebra ( Equus quagga ), are continuing to decline through habitat alteration and hunting. They now only occur to any significant degree in East Africa and

112-582: The central Zambezian region. Much of the extraordinary abundance of Guinean and Sahelian savannas has been eliminated, although the large-scale migrations of Ugandan Kob still occur in the savannas in the Sudd region. The Sudan type of climate is characterized by an alternating hot and rainy season, and a cool and dry season. In the Northern Hemisphere, the hot rainy season normally begins in May and lasts until September. Rainfall varies from 25 cm to 150 cm and

126-502: The entire year's rainfall sometimes occurring within a couple of weeks. African savannas occur between forest or woodland regions and grassland regions. Flora includes acacia and baobab trees, grass, and low shrubs. Acacia trees lose their leaves in the dry season to conserve moisture, while the baobab stores water in its trunk for the dry season. Many of these savannas are in Africa. Large mammals that have evolved to take advantage of

140-490: The front of the forelegs are black. This subspecies is native to East Africa. It occurs in South Sudan, to the west of the Nile, Uganda and the north-eastern Democratic Republic of Congo. Its range used to extend into northwestern Tanzania, where it grazed the grasslands margining Lake Victoria, and into southwestern Kenya, but it has been extirpated from these countries. It is typically found in open or wooded savanna , within

154-752: The north, the Einasleigh Uplands savanna to the northeast, and the Brigalow tropical savanna to the east. More arid ecoregions lie to west and south – the Great Sandy-Tanami desert to the southwest, the Simpson Desert to the south, and the Eastern Australia mulga shrublands to the southeast. The ecoregion includes three IBRA regions – Mitchell Grass Downs , Mount Isa Inlier , and Desert Uplands . The climate

168-614: The northern parts of South America and Australia , and the southern United States . Ugandan Kob The Ugandan kob ( Kobus kob thomasi ) is a subspecies of the kob , a type of antelope . It is found in sub-Saharan Africa in South Sudan , Uganda and the Democratic Republic of the Congo . The Ugandan kob is normally reddish-brown, differentiating it from other kob subspecies. A Ugandan kob appears on

182-410: The shoulder, with an average weight of 94 kg (207 lb), while females are 82 to 92 cm (2.7 to 3.0 ft) at the shoulder and on average weigh about 63 kg (139 lb). Apart from the throat patch, muzzle, eye ring and inner ear, which are white, the coat is golden to reddish-brown, the colour differentiating it from other kob subspecies. The belly and inside of the legs are white, and

196-512: Was recorded as travelling 150 to 200 km (93 to 124 mi) during the dry season. Sometimes non-breeding males form their own groups. Females become sexually mature in their second year, but males do not start breeding until they are older. Larger populations of kob tend to have a lek mating system, the females living in loose groups and only visiting the traditional breeding grounds in order to mate. For this purpose, males hold small territories of up to 200 m (660 ft) in diameter,
