Giant Panda

The Giant Panda (Ailuropoda melanoleuca "black-and-white cat-foot") is a mammal now usually classified in the bear family, Ursidae, native to central and southern China [1].

Pandas eat bamboo. Easily recognizable through its large, distinctive black patches on the eyes, ears and on its rotund body, the Giant Panda is one of the most endangered animals in the world: an estimated 1,600 pandas live in the wild and some 160 of them live in captivity, according to a 2004 census [2].

Giant Panda - General information

The Giant Panda lives in mountainous regions, such as Sichuan and Tibet. The Giant Panda is the symbol of the World Wildlife Fund (WWF), a conservation organization (http://www.wwf.org). Since the latter half of the 20th century, the panda has become an informal national emblem for China, and its image is found on many Chinese gold coins.

Despite being taxonomically a carnivore, their diet is overwhelmingly herbivorous. The Giant Panda eats shoots and leaves, living almost entirely on bamboo. Pandas are also known to eat eggs, the occasional fish, and some insects along with their bamboo diet. These are necessary sources of protein.

For many decades the precise taxonomic classification of the panda was under debate as both the Giant Panda and the distantly related Red Panda share characteristics of both bears and raccoons. However, genetic testing has revealed that Giant Pandas are true bears and part of the Ursidae family. Its closest bear relative is the Spectacled Bear of South America. (Disagreement remains about whether or not the Red Panda belongs in Ursidae; the raccoon family, Procyonidae; or in its own family, Ailuridae.)

Giant Pandas are an endangered species, threatened by continued habitat loss and by a very low birthrate, both in the wild and in captivity. About 1,600 are believed to survive in the wild. Poaching is uncommon; killing a panda was punishable in China by death until a 1997 law changed the penalty to 20 years imprisonment.

The Giant Panda has an unusual paw, with a "thumb" and five fingers; the "thumb" is actually a modified sesamoid bone. Stephen Jay Gould wrote an essay about this, then used the title The Panda's Thumb for a book of collected essays. The Giant Panda has a short tail, approximately 15 cm long.

The Giant Panda has long been a favourite of the public, at least partly on account of the fact that the species has an appealing baby-like cuteness that makes it seem to resemble a living teddy bear. The fact that it is usually depicted reclining peacefully eating bamboo, as opposed to hunting, also adds to its image of innocence. Though the Giant Panda is often assumed docile because of their cuteness, they have been known to attack humans, usually assumed to be out of irritation rather than predatory behavior.

Giant Panda - Natural History

No fossils of pandas have been found earlier than a few million years ago. However DNA analysis of the giant panda compared with other bears show a very early split from the main bear lineage 18 or 15 million years ago. That was about the time when the "dawn bear" (Ursavus) roamed the subtropics of Europe. Like a subtropical mammal, the giant panda does not hibernate. Fossils from Pleistocene sites throughout East Asia prove the success of the giant panda. In the Lang Trang caves of northern Vietnam, fossils of pandas were found - far away from the typical mountain forests where we see pandas today. Other fossils have been found as far south as Thailand and Burma, going as far north as where Beijing stands today. Fossils also show a second extinct panda species. This species, Ailuropoda minor, was half the size of the modern giant panda.

According to a paper published in 2002, the genome of the panda shows evidence of a severe population bottleneck which took place about 43,000 years ago¹ and the age of the most recent common ancestor of the current panda populations is estimated to be 43,000 years before present.

Giant Panda - Uses and Conservation History

Unlike many other animals in Ancient China, pandas were rarely thought to have medical uses. The only considered medical use was probably of panda urine, to melt needles accidentally swallowed in the throat. In the past, pandas were thought to be rare and noble creatures; the mother of Emperor Wen of Han was buried with a panda skull in her tomb. Emperor Taizong of Tang was said to have given Japan two pandas and a sheet of panda skin as a sign of goodwill. Panda skin was considered a sign of courage afterwards, and thus pandas became a target for poachers.

The Giant Panda was first made known to the West in 1869 by the French missionary Armand David, who received a skin from a hunter on 11 March 1869. The first westerner known to have seen a living Giant Panda is the German zoologist Hugo Weigold, who purchased a cub in 1916. Kermit and Theodore Roosevelt, Jr. became the first foreigners to shoot a panda, on an expedition funded by the Field Museum of Natural History in the 1920s. In 1936, Ruth Harkness became the first Westerner to bring back a live Giant Panda, a cub named Su-Lin who went to live at the Brookfield Zoo in Chicago. These activities were halted in 1937 because of wars; and for the next half of the century, the West knew little of the pandas.

Because of the Second Sino-Japanese War and the Chinese Civil War afterwards, foreigners were unable to poach pandas in China, but pandas remained a source of soft furs for the locals. The population boom in China after 1949 created stress on the pandas' habitat, and the subsequent famines led to the increased hunting of wildlife, including pandas. During the Cultural Revolution, all studies and conservation activities on the pandas were stopped. After the Chinese economic reform, demands for panda skin from Hong Kong and Japan led to illegal poaching for the black market, acts generally ignored by the local officials at the time.

Though the Sichuan Wolong Reserve was set up by the PRC government in 1958 to save the declining pandas, few advances in the conservation of pandas were made, due to inexperience and insufficient knowledge in ecology. Many believed that the best way to save the pandas was to cage them, and as a result, the pandas were caged for any sign of decline, and they suffered from terrible conditions. Because of pollution and destruction of their natural habitat, along with segregation due to caging, reproduction of wild pandas was severely limited. In the 1990s, however, several laws (including gun controls and moving residents out of the reserves) helped the chances of survival for pandas. With the ensued efforts and improved conservation methods, wild pandas have started to increase in numbers in some areas.

Loans of Giant Pandas to American and Japanese zoos formed an important part of the diplomacy of the People's Republic of China in the 1970s as it marked some of the first cultural exchanges between the PRC and the West. This practice has been termed "Panda Diplomacy".

By the year 1984, however, pandas were no longer used as agents of diplomacy. Instead, China began to offer pandas to other nations only on 10-year loans. The standard loan terms include a fee of up to US$1,000,000 per year and a provision that any cubs born during the loan are the property of the People's Republic of China. Since 1998, due to a WWF lawsuit, the U.S. Fish and Wildlife Service only allows a U.S. zoo to import a panda if the zoo can ensure that China will channel more than half of its loan fee into conservation efforts for wild pandas and their habitat.

By 2005, political tensions had eased between mainland China (People's Republic of China) and Taiwan (Republic of China), causing the mainland to suggest giving Taiwan two pandas as a diplomatic gift. This is met by polarized opinions from Taiwan. [3]

Giant Panda - Reproduction

Giant pandas reproduce very slowly, and infant mortality is high. Growth is slow and pandas may not reach sexual maturity until they are five to seven years old. The mating season usually takes place from mid-March to mid-May. During this time, two to five males can compete for one female; the male with the highest rank gets the female. When mating, the female is in a crouching, head-down position as the male mounts from behind. Copulation time is short, ranging from thirty seconds to five minutes, but the male may mount repeatedly to ensure successful fertilization. Mating is also a very noisy time, accompanied by moaning, squealing and happiness.

The whole gestation period ranges from 83 to 163 days, with 135 days being the average. Baby pandas weigh only 90 to 130 grams, which is about 1/900th of the mother’s weight. Usually, the female panda gives birth to one or two panda cubs. Since baby pandas are born very small and helpless, they need the mother’s undivided attention, so she is only able to care for one of her cubs. She usually abandons one of her cubs, and it dies soon after birth. At this time, scientists do not know how the female chooses which cub to raise, and this is a topic of ongoing research.

The father has no part in helping with raising the cub. When the cub is first born, it is pink, naked and blind. It nurses from its mother's breast 6–14 times a day for up to 30 minutes each time. For three to four hours, the mother might leave the den to feed, which leaves the panda cub defenseless. One to two weeks after birth, the cub's skin turns gray where its hair will eventually become black. A month after birth, the color pattern of the cub’s fur is fully developed. The cub begins to crawl at 75 to 90 days and the mothers play with their cubs by rolling and wrestling with them. The cubs are able to eat small quantities of bamboo after six months, though mother's milk remains the primary food source for most of the first year. Giant panda cubs weigh 45 kilograms at one year and live with their mother until they are 18 months to two years old. The interval between births in the wild is generally two years.

On the trivial side, pandas in captivity sometimes are not successful at mating. Usually, this is due to lack of experience. In order to tackle this problem, keepers of the bears in China have been known to show "pornographic/educational" videos to the bears, the contents being pandas having sex with each other. Amazingly, the bears get stimulated by the videos. However, it is not likely that they learn from the video itself; rather, scientists believe that the audio content of excited pandas has an impact on the bears exposed to it.

Giant Panda - Name

The name "panda" originates with a Himalayan language, possibly Nepalese. And as used in the West it was originally applied to the Red Panda, to which it was thought to be related. Until its relation to the Red Panda was "discovered" in 1901, the Giant Panda was known as Mottled Bear (Ailuropus melanoleucus) or Parti-colored Bear.

In Chinese, the Giant Panda is called the "large bear cat" (Simplified: 大熊猫; Traditional: 大熊貓; Hanyu Pinyin: Dàxióngmāo), or sometimes (usually in Taiwan) "cat bear" (Simplified: 猫熊; Traditional: 貓熊; Hanyu Pinyin: Māoxióng). Since Chinese stative verbs (adjectives) are almost always placed before nouns, the latter (cat[-like] bear) is more grammatically correct. However, the former (bear, cat[-like])) is more widely-used.

Most bears' eyes have round pupils. The exception is the giant panda, whose pupils are vertical slits, like cats' eyes. It is these unusual eyes that inspired the Chinese to call the panda the "giant cat bear".

Giant Panda - Subspecies

Two subspecies of giant panda have been recognized on the basis of distinct cranial measurements, color patterns, and population genetics (Wan et al., 2005).

Ailuropoda melanoleuca melanoleuca consists of most extant populations of panda. These animals are principally found in Sichuan and display the typical stark black and white contrasting colors.

Ailuropoda melanoleuca qinlingensis is restricted to the Qinling Mountains in Shaanxi at elevations of 1300–3000 m. The typical black and white pattern of Sichuan pandas is replaced with a dark brown versus light brown pattern. The skull of A. m. qinlingensis is smaller than its relatives and it has larger molars.

Giant Panda - Pandas in Zoos

As of 2005, four major American zoos have Giant Pandas (listed in order in which they acquired the pandas):

• San Diego Zoo, San Diego, California - home of Bai Yun (F), Gao Gao (M), Mei Sheng (M), and a female cub named Su Lin.
• The National Zoo, Washington, D.C. - home of Mei Xiang (F), Tian Tian (M), and a male cub named Tai Shan.
• Zoo Atlanta, Atlanta, Georgia - home of Lun Lun (F) and Yang Yang (M).
• Memphis Zoo, Memphis, Tennessee - home of Ya Ya (F) and Le Le (M).

There is one zoo in Mexico, the Chapultepec Zoo in Mexico City:

• Zoologico de Chapultepec, Mexico City, Mexico - home of Shuan Shuan, Xin Xin and Xi Hua, all females.

Two zoos in Europe show giant pandas:

• Zoologischer Garten Berlin, Berlin, Germany - home of Bao Bao, age 27, the oldest panda living in captivity; he has been in Berlin for 25 years and has never reproduced.
• Tiergarten Schönbrunn. Vienna, Austria.

The Chiang Mai Zoo in northern Thailand is home to Chuang Chuang (M) and Lin Hui (F).

There are no pandas any more in London, Madrid and Paris, although Madrid is exploring the possibility of obtaining pandas in the future.

On July 9, 2005, a male giant panda cub was born at the National Zoo to mother Mei Xiang and father Tian Tian through artificial insemination; it was the first surviving cub birth in the Zoo's history. For the first time in the nation's history the public got to vote on this panda's name, choosing Tai Shan (tie-SHON), which was announced on the day he turned 100 days old, following Chinese tradition.

A female cub, Su Lin, was born on August 2, 2005, to the female Bai Yun and male Gao Gao at the San Diego Zoo. Her name was also chosen by a public online poll. Bai Yun's two previous cubs were the first two giant pandas to survive past infancy in North America. The first, a female named Hua Mei, was fathered by Shi Shi via artificial insemination and was born on August 21, 1999. She returned to China in February 2004, where she has already given birth to 2 sets of twins, males in 2004 (named Hua Ling and Mei Ling) and one male/one female in 2005. Both sets of twins are doing fine to date. Bai Yun's second cub, a male named Mei Sheng, was the product of natural mating with Gao Gao and was born on August 19, 2003. Su Lin was also fathered by Gao Gao via natural mating.
