Clouded Leopard

New Species Declared: Clouded Leopard On Borneo And Sumatra

ScienceDaily (Mar. 15, 2007) — Scientists have discovered that the clouded leopard found on the islands of Borneo and Sumatra is an entirely new species of cat. The secretive rainforest animal was originally thought to be the same species as the one found in mainland Southeast Asia.

Genetic analysis conducted at the U.S. National Cancer Institute shows that the difference between the two clouded leopard species is comparable to the differences between other large cat species like lions, tigers, and jaguars. Scientists believe the new species of clouded leopard diverged from the mainland population some 1.4 million years ago.

"Genetic research results clearly indicate that the clouded leopards of Borneo and Sumatra should be considered a separate species," said Dr Stephen O'Brien, Head of the Laboratory of Genomic Diversity, U.S. National Cancer Institute. "DNA tests highlighted around 40 differences between the two species."

The results of the genetic study are supported by separate research on geographical variation in the clouded leopard, based mainly on fur patterns and coloration of skins held in museums and collections.

"The moment we started comparing the skins of the mainland clouded leopard and the leopard found on Borneo and Sumatra, it was clear we were comparing two different species," said Dr Andrew Kitchener, from the Department of Natural Sciences, National Museums Scotland and lead author of the scientific paper that described the new species. "It's incredible that no one has ever noticed these differences."

The new clouded leopard species is generally darker than the mainland species, has small cloud markings, many distinct spots within the cloud markings, grayer fur, and a double dorsal stripe. Clouded leopards from the mainland have large clouds on their skin with fewer, often faint, spots within the cloud markings, and they are lighter in color, with a tendency toward tawny-colored fur and a partial double dorsal stripe.

"Who said a leopard can never change its spots? For over a hundred years we have been looking at this animal and never realized it was unique," said Adam Tomasek, head of WWF's Borneo and Sumatra program. "The fact that Borneo's top predator is now considered a separate species further emphasizes the uniqueness of the island and the importance of conserving the Heart of Borneo."

Clouded leopards are the biggest predators on Borneo. Some grow to be as large as a small panther, and have the longest canine teeth relative to body size of any cat. Sumatran tigers are the largest predators on Sumatra.

Between 5,000 and 11,000 clouded leopards are estimated to live on Borneo. The total number in Sumatra could be in the range of 3,000 to 7,000 individuals. However, further studies are needed to obtain better population data. Habitat destruction is the cat's main threat.

The last great forest home of the Bornean Clouded Leopard is the Heart of Borneo, a wild, mountainous region of rainforest the size of Kansas. WWF recently released a report showing that scientists had identified at least 52 new species of animals and plants over the past year on Borneo.

Last month in Bali (Indonesia), the ministers of the three Bornean governments - Brunei Darussalam, Indonesia and Malaysia - signed an historic Declaration to conserve and sustainably manage the Heart of Borneo.

Borneo poisonous blowpipe

The diverse indigenous Dayak tribes, as well as the formerly semi-settled hunters and gatherers of Borneo (Kalimantan) such as the Punan, Berusu, and Basap have traditionally hunted for wild animals WILD ANIMALS.

The blowpipe, which is about two meters long, is made of ironwood ironwood: see hornbeam.

ironwood

Any of numerous trees and shrubs, found worldwide, that have exceptionally tough or hard wood useful for timber, fence posts, and tool handles. (Eusideroxylon zwageri), generally known as ulin in Indonesia, or of another hardwood species. Among my collection are also some antique blowpipes cut from bamboo sections.

The 30 cm. long blowpipe darts weigh less than 1 g. The darts exit the blowpipe at a speed (V0) of at least 50 m/see, or about 180 km/h, as ascertained through trials by the author at the German Bundeskriminalarat (German Federal Bureau of Investigation Federal Bureau of Investigation (FBI), division of the U.S. Dept. of Justice charged with investigating all violations of federal laws except those assigned to some other federal agency. ) in the city of Wiesbaden in 1985 (Zahorka 1986:37). Because of minimal weight and high velocity, the darts' trajectory is flat up to a distance of 25 to 30 meters. Therefore, at this distance, the dart can hit an animal even if only a small part of it is visible or it is shielded by branches and leaves in the dense jungle cover. This would not be possible if using a bow because the flight path of a heavy arrow is not straight but takes on a ballistic curve. Another advantage of hunting with a blowpipe is the nearly soundless shooting.

The agent that brings about the demise of the animal is the poison, not the dart itself. Irrespective of which part of the animal's body the dart hits, the poison diffuses very rapidly throughout the whole body. A two-centimeter segment of the points of the darts used for hunting small animals, monkeys and large birds is treated with poison. The darts for hunting deer (Cervus unicolor u·ni·col·or

Because of the depletion of the forests in Kalimantan, the present indigenous hunters need a hunting weapon that can be shot over a much greater distance than the blowgun blowgun, hollow tube from which a dart or an arrow is blown by a person's breath. The arrow was usually tipped with a poison, such as curare, which would stun or kill the struck prey. Blowguns were widely used by prehistoric peoples. . Therefore, some Basap people living on the Mangkalihat Peninsula, Kalimantan Timur, have constructed sophisticated air guns powered by strings of elastic, which shoot these poison darts accurately at a distance of about 100 meters (Zahorka 2004a:10).

The Plant Species Needed to Produce the Dart Poison

The raw material that yields the poison is the latex of the tall tree Antiaris toxicaria (Pers.) Lesch., Moraceae. However, the poison processing is possible only with the use of a young leaf of the small Licuala spinosa Thunb. palm.

1. Antiaris toxicaria (Pers.) Lesch., Moraceae, can grow up to 50 meters in height and to a diameter of up to 1.5 meters or more. The tall branchless trunk is straight; the buttresses are relatively small, and the small treetop is nearly spherical. It is a rare tree that grows from the lowland up into the montane mon·tane

[Latin montnus, from m tropical forest. Generally, the lower parts of the trunks display numerous scars, which indicate former latex tapping over many decades.

Because of its powerful poison, this tree has been the subject of horror stories for 200 years. Thus, the seventeenth century German-Dutch natural scientist Rumphius wrote: "This tree grows on barren mountains. The soil below it is desolate and singed. Only a horned snake lives under the tree which cackles like a hen and has eyes that glow in the night" (cit. Beekmann 1981 in Zahorka 2000:19, translated by the author). Similarly, the Swedish Borneo explorer Eric Mjoberg reported in 1929: "To stay at a close distance to the tree is life-threatening and an embankment of bones surrounds it ..." (Mjoberg 1929:307, translated from German by the author). Fortunately, this all is pure fantasy. In a more recent book, we can read: "There is a fabulous legend that it is deadly merely to sleep in the shade of the upas tree upas tree (y`pəs): see mulberry. " (Smith 1997:36).

In Java, Sumatra and Malaysia, the tree is widely known as pohon ipoh or pohon upas. However, the various traditional tribal communities in Kalimantan have their own vernacular names for it. Here are some examples which I collected in East and Central Kalimantan between 1976 and 2003:

2. Licuala spinosa Thunb., Palmae, is a small fan palm growing in the tropical forests of SE Asia along the equator (McCurrach 1960). The 3-to-5-meter-high stems grow in tufts. The 15 to 18 leaf segments, which are up to 40 centimeters long and up to 15 centimeters wide are widely used for thatching. The Indonesian and Malaysian name for it is sang.

For the dehydration process of the Antiaris latex, a very young sang leaf, that is still accordion-like folded and not yet spread out, is used. In this original condition, the leaf is absolutely fire resistant and durable. It is this property of the leaf that holds the secret of producing the dart poison over a fire. The young leaf keeps its shape and will not burn even if put into a hot gas flame. A boat-shaped container made with this leaf must be durable enough to hold the latex throughout the prolonged dehydration.

Building the Iban Longhouse

A longhouse in Sarawak; source:www.enicholl.com

"When the longhouse becomes too dilapidated, it is the responsibility of the tuai rumah (leader of the longhouse) to hold a gathering with his people to discuss about a new longhouse. If the head of each family agrees, all males and every family is asked to collect ramu (construction materials) for posts, beams, studs, planks, etc. When all the families report that they have enough ramu, the tuai rumah with the help of the tuai burung (the sage) will fix the auspicious date for the ngerembang, the clearing of the site of the longhouse."


The Tanju, the outdoor communal terrace

"A few days before that date, the tuai rumah goes into the jungle to seek the signs that will reveal the best location of the future longhouse. If the new longhouse is to be built downstream from the old house, the tuai rumah will look for the Nendak bird, to the right of his direction of travel. When he hears the call of this bird, he will uproot a small tree in that area to mark the occasion, , and he will bring home the small tree, known as the tambak burung."

"The next day, the tuai rumah enters the jungle again on a similar mission. When he hears the call of the nendak bird from his right hand side, he will again uproot a young tree to mark the spot and return with the tambak burung. Early on the third day, he again enters the jungle, this time looking for the bird on his left hand side. When he hears the call, he will again uproot a young tree and return with his last tambak burung."


The Panggau and the Ruai, communal living areas in the longhouse

"On the morning of the ngerembang, the tuai rumah will burn the tambak burung in the middle of the new site, before leading the members of the longhouse in the clearing works. When the ngerembang is finished, the families are asked to bring all the ramu that had been collected to the respective houses."


The bilik is the private realm of the family

"After the prayer, the tiang permun (the main post of the house) is placed in the ground, buried together with salt, a small piece of gold, the skin of the langgir fruit and a mumban twig (a small tree commonly found along the river banks). As soon as the longhouse is completed, the tuai rumah and the tuai burung will lead the the families into the new building. But before they finally move to their bilik (rooms), each family must build their own dapur (kitchen)."

Iban longhouse

The longhouse faces the river. Each family unit in the longhouse has its own section, consisting of a room (bilik) with a solid door, an equal-width section of the common area onto which all rooms open, and an equal-width section of the porch (tanju) -- which, as you can see, is a rickety affair made of split bamboo laid (not fastened) across supporting logs. We tourists were warned not to go out on the porch because it likely would not hold our weight, and believe me, we were not tempted. In addition to hanging laundry, the porch is used for doing work. An old man spent the morning out there building a door from fresh-looking boards.

Below, you can see some chicken coops on the left side, beneath the living quarters. The people kept a large number of chickens, which strut all around but are chased out if they come into the house. Several dogs and one very small, friendly, flea-infested cat shared the house. The people raise fish to eat in their own fish farm on the river; big bags of tilapia feed are stacked inside the longhouse.

First thing in the morning, most women went out to gather some food. They raise padi rice, vegetables and pepper on the hills above the house. (Black pepper is a major export of Sarawak; we saw pepper plants trained to climb poles in long rows everywhere as we traveled the roads.) The women strap a giant cylindrical basket on their back, put a conical hat on their head, and wearing long sleeves and usually pants, climb up a narrow path to the cultivated fields. When they return, the basket is filled with greenery. They make the baskets from grasses and rattan; the straps are made from tree bark.

One of the two women who cooked for us came in with what appeared to be some kind of tree leaves brimming from her huge basket. Later I realized I had heard a dull pounding coming from the kitchen for a very long time, so I went to investigate. In a small stone mortar she was mashing all the leaves to pulp. She already had a big blue plastic basin full of it. I signaled that I would like to try it and she gestured permission. But she had meant touch and not taste, because as I moved to put a clump into my mouth, both women urgently warned me not to do it. Pointing to the wok on the double-burner gas cooker (same as what most city Malaysians also use), they explained that the pulp had to be cooked. We ate it at lunch that day, and like everything we ate in the longhouse, it was delicious. The texture was heavier than chopped spinach but equally smooth. I don't know if they cooked it in chicken stock or just a combination of flavorings such as soy sauce, but the unique taste of the leaf remained, neither sweet nor bitter, a cross between mustard greens and collards.
