The big cats prowling the jungles of Borneo and Sumatra had long been assumed to be the same clouded leopards that are found in mainland Asia. Genetic analysis and comparisons of fur patterns have now shown the two animals to be as distinct as the lion and the tiger, the WWF announced yesterday. Among the findings that convinced scientists was the realisation that the Bornean cat has changed the number and prominence of its spots.

The cats have now been reclassified as the Bornean clouded leopard, with the name Neofelis diardi, to distinguish them from other clouded leopards, Neofelis nebulosa. The two species, both endangered, are shown by genetic analysis to have separated 1.4 million years ago, after the animals used a land bridge, now covered by water, from mainland Asia to reach Borneo and Sumatra.

Just as the Byzantine empire represented the political continuation of the Roman Empire, Byzantine art developed out of the art of the Roman empire, which was itself profoundly influenced by ancient Greek art. Byzantine art never lost sight of this classical heritage.

An isosceles triangle has at least two congruent sides. An equilateral triangle has three congruent sides. So, an equilateral triangle is a special case of isosceles triangles. Since the equilateral triangle has three congruent sides, it satisfies the conditions of isosceles triangle. So, equilateral triangles are always isosceles triangles.

Bangladesh, April 25 -- Education provided by the primary schools of our country is the root of all education on which depends the future of our country. But the bleak position of most of our government primary schools weakens the contribution to building up the foundation of our children. Almost every year the government is recruiting the teachers in the primary school through a written test and a viva voce. But very often many applicants fail to get the required marks in the exam but they...

A kite is a flying tethered aircraft that depends upon the tension of a tethering system.[1] The necessary lift that makes the kite wing fly is generated when air (or in some cases water)[2][3][4] flows over and under the kite's wing, producing low pressure above the wing and high pressure below it. This deflection also generates horizontal drag along the direction of the wind. The resultant force vector from the lift and drag force components is opposed by the tension of the one or more lines or tethers.[5] The anchor point of the kite line may be static or moving (e.g., the towing of a kite by a running person, boat,[6] or vehicle).[7][8] Kites are usually heavier-than-air, but there is a second category of lighter-than-air kite called a helikite which will fly with or without wind. Helikites work on a different stability principle to normal kites as helikites are helium-stabilised as well as wind stabilised. They are a stable combination of a helium balloon and kite-sail to create a single aerodynamically sound kite. When flown in wind a helikite will lift far more than its helium alone, and it will fly very well if weighted down to be considerably heavier than air. Kites may be flown for recreation, art or other practical uses. Sport kites can be flown in aerial ballet, sometimes as part of a competition. Power kites are multi-line steerable kites designed to generate large forces which can be used to power activities such as kite surfing, kite landboarding,kite buggying and a new trend snow kiting. Kites towed behind boats can lift passengers[9] which has had useful military applications in the past.[10]

The glorious land of the Afghans is now the focus of much political attention and social divide. However, a closer look at the region makes it easy to understand current events. The people here flaunt a culture and tradition that are the result of ancient trade and migration. The customs that have emerged and survived greatly compliment its geostrategic location, and a long tryst with invaders and individual empires. Modern Afghanistan is well grounded in its beliefs and customs, even as it is open to change. This buffer state is no more one; it has emerged as a power to reckon with. Afghanistan has always influenced world cultures and heritage, more than their military or political mindset. A rich tradition in ancestry and pride in personal honor are characteristics that offer a glimpse of the land and its people. Modern Afghanistan is hardly any different from the older version, physically. However, the influence of neighboring countries and the remnants of a terrible civil war have made the people vary of foreign intervention. The people of Afghanistan are friendly and hard-working. Their lives and vocations are centered around the home. Women are treated with utmost respect and honor.

Poison-arrow frogs are social frogs found in Central and South America. They are known by their bright colors which warn other animals that they are poisonous. Its poison is one of the most powerful known and can cause paralysis or death. It is so potent that one millionth of an ounce can kill a dog and an amount smaller than a grain of salt can kill a human. One frog carries enough poison to kill about 100 people. Native hunters use it on the tips of their arrows which is how the frog got its name. Poison-arrow frogs are about the size of a man's thumbnail (less than one inch). The tiny frogs lay their eggs on leaves. When the tadpole hatches, it is carried on one of the parents' back to a bromeliad where the parents feed it small insects, ants, spiders, crustaceans, and tiny water animals. The mother frog may also lay infertile eggs as food for the tadpoles. Poison-arrow frogs are beautiful to look at. Their colors vary from red to yellow to blue. The enemies they encounter are large animals (including humans) who may step on them. Though poison-arrow frogs carry a deadly poison, they are usually harmless if left alone.

What We Can Do To Save Them Learn and Share Information The first step toward saving the rainforests is to learn about them. Through reading we can explore the wonders of the rainforests without ever visiting them. Once we learn about them we need to share our knowledge with others. Letters to our congressional representatives can influence those in power and encourage discussion on the rainforest. And by talking to friends about the rainforests another person can become active in saving the them. Join Groups We can join a conservation group. The group can tell us what needs to be done to save the rainforests and how we can help. Or we can volunteer with the local zoo, nature center, botanical garden, or museum. We can learn a lot from the professionals that work there. Begin at Home Our own homes provide many chances to help save the rainforests. We can recycle all reusable materials. We can learn to use products made from rainforests in a thoughtful way. And we can protect living things in our own backyard. The plants and animals there also need protection. Ask Questions We can protect illegal trade of animals and plants from the wild by asking questions. We need to ask store owners if the plants and animals they sell were taken from the wild. Unless we ask questions, illegal trade will continue. Illegal trade leads to endangered species and extinction. Think Globally And we can encourage our local or national conservation organizations to help save the rainforests. It is necessary for all of us to be aware of and help with saving the rainforests. Although the rainforests cover on ly a small area of the world, far away from many of our homes, they have an effect on all of us.

Some humans benefit from decreasing the size of the rainforest - people who use the electricity caused by a hydro-electric dam, for example. Other humans do not have it so good - people who hunt wildlife for a living may a tougher time finding food. The loss of indigenous culture is kind of sad. Read Tristes Tropique by the anthropologist Claude Levi Strauss to learn more about people who are hurt by the loss of forest. "Under developing the Amazon" by Stephen Bunker is a good look at the costs and benefits, who gains and who loses from the destruction/development of the rainforests.

Mojave National PreserveWorld Deserts World Deserts North American Deserts Protecting Deserts Home Desert lands cover incredible distances. Many who have driven through deserts in the United States may think they are enormous, but they are only the fifth largest in the world covering about 500,000 square miles. By contrast the great Sahara Desert covers almost 3.5 million square miles, the Australian deserts 1.3 million square miles, the Arabian deserts 1 million square miles, while the deserts of Turkestan have 750,000 square miles. Numerous smaller deserts are also scattered across the globe. All are unique, and have adapted to their own particular environments. Global Weather PatternsDeserts tend to occur in two belts that circle the globe. Both the Northern and Southern Hemisphere have this belt located between 15 and 35 degrees latitude, roughly centered over the Tropic of Cancer and the Tropic of Capricorn. This is no accident. The sun is more directly overhead the equatorial region so it receives the most intense sunlight, and this solar energy heats the air. Hot air has two important qualities: it can hold enormous quantities of moisture, and it rises up into the atmosphere. So hot tropical air tends to be moist and rise into the atmosphere. As this air rises it cools, condensing the moisture and converting it to water where it falls as rain. This is why rain forests tend to occur near the equator. What goes up must come down, and gravity pulls this mass of rising air back to the ground. Tropical air typically falls at about 30 degrees latitude on either side of the equator and along the desert belt, but robbed of its moisture it is now hot and dry. The result are often persistent high pressure systems that tend to block incoming storms, or push them into other regions. These patterns make deserts possible, but typically other factor must also intrude to make deserts a reality.

They wear little clothing because it is always warm in the rainforest. They make their clothing from leaves and things they find in the rainforest, too. Their way of life is in danger because of the destruction of the rainforest that they live in. The government has tried to teach them how to farm, but the Mbuti don't want to change the way they live.

The World's Lungs? In the past, scientists often referred to tropical rainforests as the "lungs of the world" because of the large amount of oxygen they produce. More recent evidence shows that rainforests don't have much of an effect on the world's oxygen supply. The decomposition of dead plant matter consumes roughly the same amount of oxygen that the living plants produce. But rainforests do play a key role in the global ecosystem. Some experts are now calling them the "air conditioners to the world," because their dark depths absorb heat from the sun. Without the forest cover, these regions would reflect more heat into the atmosphere, warming the rest of the world. Losing the rainforests may also have a profound effect on global wind and rainfall patterns, potentially causing droughts throughout the United States and other areas

The jaguar lives in biodiversity-rich regions of Central and South America. It prefers forest habitats and areas close to water sources (such as wetlands, rivers, lakes etc) as it loves water and is a great swimmer. For example, the Amazon River Basin and the wetland area of Pantanal in Brazil are home to important populations of jaguars (1).

The jaguar is a nocturnal animal – it hunts for prey mostly during the dark hours of the day. (3) Though we have heard of some recent evidence of the jaguar’s daytime hunting as well. (4) The jaguar is a very adaptable animal.

jaguars … hunt by stealth, ambushing their prey from dense cover. Long canine teeth and powerful jaw muscles enable them to kill large animals swiftly, often with a single bite to the nape.

Sahara Desert Plants The Sahara Desert is often described as a bleak and barren plain. In truth, it is very beautiful and full of different Sahara Desert plants. Sahara Desert Plants Among desert areas throughout the Earth, there are two types. The cold type of desert, which is often found in Arctic regions, is an area that gets very little precipitation. The cold desert can be covered in snow, however, and the temperatures here are chilly and unsuitable for sustaining many life forms. The other type of desert is known as the hot desert, and this is what people usually think of when they picture a desert area. This type of desert is extremely warm and dry, with temperatures reaching unbearable levels, and little to no rain to sustain those who live here. The biggest of the hot deserts is the Sahara Desert, located in Africa. Although this desert is not the most hospitable place for organisms to take up residence, the Sahara Desert plants defy the odds and thrive here.

The Reticulated Python is located in Southeast Asia in countries including but not limited to Vietnam, Malaysia, Indonesia and the Philippines.

The Reticulated Python's diet consist of birds, mammals of different sizes including deer and pigs and on very rare occasions possibly humans.  Pythons will typically wait in hiding for prey to move close by before striking.  The Reticulated Python is not venomous; like other members of the Boa family it will use its large muscular body to constrict and suffocate its prey.  HabitatThe Reticulated Python can usually be found near water, including ponds and rivers, in warm and humid tropical rainforests of southeast Asia.  They may also have a tendency to live near human activity.     SizeThe average length of an adult Reticulated Python can range from 15 - 25 feet making it the longest snake and reptile in the world.  It is possible for Reticulated Pythons to grow over 30 feet in length.  The adult weight can be over 300 pounds.ReproductionUnlike other members of the Boa Family who bear live young, Pythons will lay eggs.  The female Reticulated Python can have between 25 - 100 eggs at a time.  The mother will coil around the eggs and create muscular vibrations to raise the temperature of the eggs several degrees.

The typical fantasy Dwarf is, like the original Dwarves, short in stature, long-bearded and skilled at mining and metallurgy. They are often depicted as having a low affinity for most magical abilities and/or a resistance to magic.
