Classification
Biology Classification Zebras have a distinctive striped pattern that makes them easily recognizable to most people, but they also display features common to many other animals. So how can we easily compare animals? This is a print version of an interactive online lesson. To sign up for the real thing or for curriculum details about the lesson go to www.cosmoslessons.com Introduction: Classication Why do zebras have stripes? It’s a question that scientists have been asking for more than 100 years but now new research may nally have an answer. Most animal species have developed distinctive colours and patterns to help disguise them in their natural environment. Like a soldier’s camouage, the colouring and patterns look like the background, so it's hard to tell the dierence between the animal and its surroundings. But zebras live on brown grassy plains and their stripes make them stand out, not disappear. They may as well be holding signs for the lions saying, “come and eat me”. Now we may have the answer. By studying where most zebras live, scientists have found that the animals share their home with lots of nasty biting tsetse ies and horse ies. They also discovered that these ies don’t like striped patterns and will stay away from them. So, it’s likely that the zebras developed stripes to act as an insect repellent. That may sound crazy – to make yourself a target for lions just to keep away the ies. But these aren’t ordinary irritating ies. Tsetse ies carry diseases that can kill, while horse ies tear the animals’ skins leaving them at risk of infections. -
Pleistocene Palaeoart of Africa
Arts 2013, 2, 6-34; doi:10.3390/arts2010006 OPEN ACCESS arts ISSN 2076-0752 www.mdpi.com/journal/arts Review Pleistocene Palaeoart of Africa Robert G. Bednarik International Federation of Rock Art Organizations (IFRAO), P.O. Box 216, Caulfield South, VIC 3162, Australia; E-Mail: [email protected]; Tel.: +61-3-95230549; Fax: +61-3-95230549 Received: 22 December 2012; in revised form: 22 January 2013 / Accepted: 23 January 2013 / Published: 8 February 2013 Abstract: This comprehensive review of all currently known Pleistocene rock art of Africa shows that the majority of sites are located in the continent’s south, but that the petroglyphs at some of them are of exceptionally great antiquity. Much the same applies to portable palaeoart of Africa. The current record is clearly one of paucity of evidence, in contrast to some other continents. Nevertheless, an initial synthesis is attempted, and some preliminary comparisons with the other continents are attempted. Certain parallels with the existing record of southern Asia are defined. Keywords: rock art; portable palaeoart; Pleistocene; figurine; bead; engraving; Africa 1. Introduction Although palaeoart of the Pleistocene occurs in at least five continents (Bednarik 1992a, 2003a) [38,49], most people tend to think of Europe first when the topic is mentioned. This is rather odd, considering that this form of evidence is significantly more common elsewhere, and very probably even older there. For instance there are far less than 10,000 motifs in the much-studied corpus of European rock art of the Ice Age, which are outnumbered by the number of publications about them. -

Wildlife and Wild Places in Mozambique K
Wildlife and Wild Places in Mozambique K. L Tinley, A. J. Rosinha, Jose L. P. Lobao Tello and T. P. Dutton This account of the national parks, reserves and other places worthy of pro- tection in Mozambique gives some idea of the wealth of wildlife in this newly independent country. One special reserve has 25,000 buffaloes—the largest concentration in the world. Protected conservation areas in Mozambique fall into six categories: 1. Parques nacionais - national parks; 2. Reservas especiais - special game reserves; 3. Reservas parciais - partial reserves; 4. Regimen de vigilancia - fauna protection zones; 5. Coutadas - hunting and photographic safari areas, normally run on a private concession basis; 6. Reservas florestais - forest reserves. Some unique areas are still outside this system but have been recommended for inclusion, together with other ecosystems worthy of inclusion in the future. Game farming or ranching is attracting considerable interest; one private and one government scheme have been proposed. NATIONAL PARKS 1.* Parque Nacional da Gorongosa (c. 3770 sq km). Situated at the southern limit of the great rift valley with an extensive flood plain and associated lakes, this park includes Brachystegia woodland Acacia and Combretum savanna. Sharply rising inselbergs (volcanic protrusions) are also a feature. The ungulates are typical floodplain species, including elephant (abundant), buffalo, wildebeest, waterbuck, zebra, reedbuck, impala and oribi; on the elevated woodland and savanna habitat there are black rhino, eland, Lichten- stein's hartebeest, sable, kudu, nyala, Sharpe's grysbok, suni, blue and grey duiker, and klipspringer are common on rock outcrops; lion, leopard and hippopotamus are abundant. Both land and water birds are prolific and diverse, and crocodiles are very common. -

GORDON when he discovered the Orange River at "De Fraaye Schoot" near the present Bethulie, probably on the 23rd December 1777. I. INTRODUCTION When the government of the Republic of South Africa in the early sixties decided to initiate a comprehensive water development scheme of its largest single water resource, the Orange River, this gave rise to a wide range of basic and applied scientific sur veys of that area. The reasons for these surveys were threefold: (1) The huge capital investment on such a water scheme can only be justified economically on a long term basis. Basic to this is that the waterworks be protected, over a long period of time, against inefficiency caused by for example silting. Therefore, management reports of the catchment area should.be produced. (2) In order to enable effective long term planning of the management and use of the natural resources in the area it is necessary to know the state of the local ecosystems before a major change is instituted. -

Orange River Project
ORANGE RIVER PROJECT: OvERVIEW South Africa NAMIBIA BOTSWANA Orange-Senqu River Basin Vanderkloof Dam LESOTHO Gariep Dam LOCATION SOUTH AFRICA The Orange River Project (ORP) is the largest scheme in the Orange–Senqu River basin, and includes the two largest dams in South Africa, the Gariep and Vanderkloof. They regulate flows to the Orange River and increase assurance of supply. DESCRIPTION Gariep and Vanderkloof dams were constructed as part of the project, and have a combined storage of 8,500 million m3. The ORP includes several sub-systems. The Orange–Riet Water Scheme.* The Orange–Fish Transfer Tunnel.* The Orange–Vaal Transfer Scheme.* Bloem Water: Pipeline network between Gariep Dam and the towns of Trompsburg, Springfontein and Philippolis. Irrigation abstractions: Between Gariep Dam and downstream of Vanderkloof Dam, up to the confluence of the Vaal and Orange rivers (near the town of Marksdrift). Urban and industrial abstractions: Between Gariep Dam and Marksdrift (including Hopetown and Vanderkloof towns). Support to the Lower Orange Water Management Area Schemes: * Support to most of the demands in the Gariep Dam (© Hendrik van den Berg/Panoramio.com) Lower Orange, including irrigation, urban use and power generation. Caledon–Bloemfontein Government Water Scheme.* * Further details are given on separate pages PURPOSE The purpose of this very complex scheme is to supply demands within several sub-systems, including the Upper and Lower Orange water management areas all the way down to the Orange River mouth, and the Eastern Cape Province. These demands include irrigation, urban, industrial and environmental water requirements. Power generation is also part of the system, including at Gariep and Vanderkloof dams, which contributes to the Eskom national power grid. -
Zebra and Quagga Mussels
SPECIES AT A GLANCE Zebra and Quagga Mussels Two tiny mussels, the zebra mussel (Dreissena poly- morpha) and the quagga mussel (Dreissena rostriformis bugensis), are causing big problems for the economy and the environment in the west. Colonies of millions of mussels can clog underwater infrastructure, costing Zebra mussel (Actual size is 1.5 cm) taxpayers millions of dollars, and can strip nutrients from nearly all the water in a lake in a single day, turning entire ecosystems upside down. Zebra and quagga mussels are already well established in the Great Lakes and Missis- sippi Basin and are beginning to invade Western states. It Quagga mussel takes only one contaminated boat to introduce zebra and (Actual size is 2 cm) quagga mussels into a new watershed; once they have Amy Benson, U.S. Geological Survey Geological Benson, U.S. Amy been introduced, they are virtually impossible to control.
