Causes: *The main cause of animal extinction, without doubt,is human demand, either for animal resources directly, or for the natural resources of the animals' habitats. *In addition to that, there are other indirect causes caused by human activities. *Habitat loss: Is considered to be the main cause for animal extinction. Humans are clearing our forests for wood and timber. The foodchain is disturbed and animals will die. *Wildlife trade: Poaching and wildlife trade are another common threat to animals. International wildlife trade has also been linked to drugs trade. The most common anilmal trade is pet trade, such as orangutangs. Animals are also killed for fur(tigers, leopards, cheetahs) *Climate change: It has been recently suggested that warmer global temperatures may be affecting animals. In fact, it has been suggested that the golden toad became extinct because of the warmer climate. The Animals *T-REX: Tyrannosaurus rex was one of the largest land carnivores of all time. His
AMBER AND RUSSET - LATE COLOUR CHANGE GENES Copyright 2014, Sarah Hartwell The ancestors of the domestic cat were nondescript black/brown striped tabbies. Over the centuries, mutation produced a wide array of colours based on 2 different pigments. Eumelanin gives the blacks, browns and blues while phaeomelanin gives the reds, fawns and creams. A few other genes give further variations on those colours such silvers, colourpoints and solids/selfs. Mutations continue to occur and unexpected colours also turn up due to inbreeding where recessive genes, hidden for generations, start showing up. AMBER AND LIGHT AMBER During the 1990s, some purebred Norwegian Forest Cats in Sweden produced chocolate/lilac and cinnamon/fawn offspring. However, those colours are not found in the purebred Norwegian Forest Cat gene pool. Had the gene pool become polluted by someone, perhaps generations ago, breeding their Norwegian Forest Cat to another breed? Was it a spontaneous mutation? Crossing of those c

The Giant Eland The Giant Eland (Taurotragus derbianus also known as the Lord Derby Eland) is an open forest savannah antelope. It is found in Central African Republic, Sudan, Cameroon and Senegal. There are two subspecies: the endangered T. d. derbianus, found in Senegal's Niokolo-Koba National Park, and the low risk T. d. gigas, found in Central Africa. Characteristics Giant Eland are typically between 220-290 cm (7.3-9.6 ft) in length, stand approximately 150 to 175 cm (4.9 to 5.7 ft) at the shoulder, and weigh 440-900 kg (968- 1,980 lb). Despite its common name, it is of very similar size to the Common Eland. The smooth coat is reddish- brown to chestnut, usually darker in males than females, with several well-defined vertical white stripes on the torso. A crest of short black hair extends down the neck to the middle of the back, and is especially prominent on the shoulders. The slender legs are slightly lighter on their inner surfaces, with black and white markings just above t

Australia Australia is a country and also a continent. If someone wants to make clear, that he is speaking of the country, he may call it by its full name of Commonwealth of Australia. Australia's name means "southland."It is south of the equator. Sometimes it is also called the island continent because it is an island. There are about twenty million people in Australia.It is 1,800 miles from the mainland of Asia and almost half way round the world from Europe. More than 600 miles of ocean separate it from Americas. Since Australia is south of the equator, its seasons are just the opposite of ours. It has summer while we have winter, and the other way round. States and Territories. Australia consists of six states, two territories and eight external territories. The six states are: Western Australia (capital Perth), South Australia (capital Adelaide), Queenslnd (capital Brisbane), New South Wales (capital Sydney), Victoria (capital Melbourne
