Miracle Recovery for World’s Rarest and Strangest Deer – Just 39 Became 8,200

Tramping through coastal marshlands in eastern China, a strange looking deer roams freely in herds of hundreds; a remarkable recovery from where they had been just a few decades ago.

Described in ancient China as a beast with the antlers of a deer, hooves of an ox, face of a horse, and tail of a donkey, PÚre David’s deer was at one time the rarest of its kind on Earth.

Hunted to extinction in the wild 125 years ago, captive animals clung to life in a far away land, until in 1985, their descendants could return to a wiser China where a more eco-conscious population welcomed them home to the quiet marshlands.

In the early 20th century, the British nobleman and politician Herbrand Russell, 11th Duke of Bedford, acquired a few PÚre David’s deer from the Berlin Zoo and built up a large herd on his estate at Woburn Abbey.

In 1985 the duke’s great-grandson Robin Russell, 14th Duke of Bedford, donated 39 PÚre David’s deer to the Chinese government for a reintroduction program. They were placed in a park/reserve that once belonged exclusively for canned hunts conducted by the emperors in Beijing—the killing field had become a sanctuary.

A second re-introduction into China was conducted in 1986 where 36 PÚre David’s deer were chosen from five UK zoological gardens. From less than 100, these original animals have multiplied into 8,200 and seem—as if by a miracle—not be be suffering from low genetic diversity. They enjoy a 17% annual growth rate in the population.

Today, all of the deer that roam China are descended from Russel’s herd, and across China’s many elk sanctuaries like Tianezhou and Dafeng, dozens of square miles of pristine habitat are protected for this incredible animal. Plans are underway to reintroduce the deer to much more wild areas, where they will have to learn to avoid predators and battle the elements once again.

A Chinese-language moniker for the PÚre David’s deer translates to “the four dislikes” referring to the component appearance mentioned above. As is so often the case in Chinese society, this strangeness is paired with a legend.

The following was taken from Wikipedia,

According to Chinese legend, when the tyrant King Zhou of Shang ruled the land more than 3,000 years ago, a horse, a donkey, an ox and a deer went into a cave in the forest to meditate and on the day the King executed his minister Bigan, the animals awoke from their meditation and turned into humans.

They entered society, learned of the King’s heinous acts and wanted to take recourse against the King, who was powerful. So they transformed themselves into one creature that combined the speed of the horse, the strength of the ox, the donkey’s keen sense of direction and the nimble agility of the deer.

This new animal then galloped to the Kunlun Mountains to seek the advice of the Primeval Lord of Heaven. The Lord was astonished at the sight of a creature that had antlers of a deer, hooves of an ox, face of a horse and tail of a donkey.“It’s unlike any of four creatures!” he exclaimed. Upon learning of the animal’s quest, Lord gave his blessing and dispatched the creature to his disciple the sage Jiang Ziya, who was battling the King. Jiang Ziya rode the creature to victory over the King and helped found the Zhou dynasty. Miracle Recovery for World’s Rarest and Strangest Deer – Just 39 Became 8,200

Biodegradable Plastic Made from Bamboo Is Stronger and Easy to Recycle

GNN has reported previously on how versatile bamboo is for construction and craft, so it maybe shouldn’t be a surprise that researchers in China have found a way to turn this miracle plant into plastic.

While many biodegradable materials have already been developed for replacing lighter, flexible plastic, durable or rigid plastic replacements are few. The kinds of plastic used for tools, car interiors, and appliance exteriors have few if any biodegradable replacements.

Enter Dawei Zhao at Shenyang University of Chemical Technology in China’s far northeast, who has developed a method for turning cellulose from bamboo into a rigid yet biodegradable plastic that outperforms not only alternative biodegradable options, but plastic itself for mechanical strength and thermo-mechanical properties.

“Bamboo’s rapid growth makes it a highly renewable resource, providing a sustainable alternative to traditional timber sources, but its current applications are still largely limited to more traditional woven products,” Zhao told New Scientist.

His method takes cellulose from bamboo and subjects it to zinc chloride and a simple acid to break up the complex polysaccharide bonds that hold this plant fiber together. Next they add ethanol into the soup of smaller molecules, and from that derive a plastic for use in injection, molding, and machining manufacturing techniques.

One major drawback is the bamboo plastic’s inflexibility, which limits its incorporation into the full gamut of products that petroleum-based plastics can fulfil. On the other hand, however, these are often the plastics that remain in the ecosystem longest, and are the hardest to recycle. Therefore replacing them still represents a valuable contribution to reducing the overall plastic burden in the environment and waste streams.

Zhao and his team published a paper on the process and properties of the bamboo plastic in Nature, including in which is a cost-analysis that finds the bioplastic’s recyclability emerges as a value that sees it attain cost-competitiveness with conventional plastic.
