Qinling panda

It differs from the more familiar nominate subspecies by its smaller skull and dark brown and light brown (rather than black and white) fur, and its smaller overall size.[4] Its eye spots are under the lower lid, instead of around the eyes. Brown pandas are exceedingly rare.

This subspecies is restricted to the Qinling Mountains, at elevations of 1,300–3,000 metres (4,300–9,800 ft). Its coloration is possibly a consequence of inbreeding: as the population is closed off from genetic variation and this might have led to the preservation of the mutation responsible.[2][4]

There were an estimated 100 Qinling pandas living in the wild as of 2001.[4]

On August 30, 1989, a female of this species was captured and brought to the Xi'an Zoo to be mated with a regular giant panda. This panda's offspring was black-and-white, but reportedly started becoming brownish as it aged. According to other reports she gave birth to three cubs, all of whom died shortly after being born. The mother, named Dan-Dan, died in 2000.[5]

Due to the Qinling subspecies being restricted in range, it has been exposed to metal toxicants such as copper, nickel, lead, and zinc that are now present in bamboo and soil as a result of the environmental pollution that is ongoing in China. More specifically, studies have indicated that the Qinling subspecies faces such anthropogenic threats so directly due to the fact that heavy concentrations of metals in bamboo and soil are positively correlated with high elevations, thus the Qinling Mountain Range is increasingly affected.[6]

Dental health is important for the survival of the Qinling Pandas. These pandas have a survival rate of 5–20 years. The most common dental abnormalities that Qinling Pandas face are dental attrition and fractures. These two abnormalities can impact the survival rate of these pandas.[7]
