King Cobra III

A couple days after our recent run-in with a king cobra, Pan pulled the snake out of the freezer for a full dissection.

He and his assistants spent a couple hours weighing, measuring, counting rings, extracting venom, and IDing organs. The cobra was likely 2-3 years old—on the cusp of breeding age—was just shy of 2 meters long, weighed 900 g (2 lbs), and had 56 dark bands from head to tail.

Like all king cobras
, it likely fed exclusively on other snakes and may have limited its diet even further to a single species.

At one point Pan entertained thoughts of extracting the cobra's venom and injecting it, bit by bit, into a pig or water buffalo to cultivate antivenom. If someone was then bit on the reserve, they could simply withdraw some blood from the by-then-resistant animal and inject it into the stricken person.—Snake antivenom available in hospitals worldwide is obtained in more or less the same way, by slowly building up venom antibodies in a horse or sheep.

King Cobra II

I started walking back to my room at the Chongzuo EcoPark the other evening after watching the langurs come down the mountain to their roost.
It was a warm evening and I'd stayed watching them settle into their cliff face caves a bit longer than usual. By the time I began the roughly 15 minute hike back to the reserve's headquarters, it was already quite dark.
I hadn't bothered to pack a flashlight as I knew the path fairly well and preferred to let the moonlight guide me.
Then, I started thinking about all the warnings I'd recently read about cobras. I flipped open my cell phone for what little light it offered and grabbed the first stick I could find.
After a couple minutes of fumbling around, Jintong, one of the reserve's staff, drove towards me driving an electric cart. He said he'd just run over a snake and proceeded to unfurl a very recently deceased, very large king cobra. He hit the snake on the path I was about to walk down, about 100 meters from my room.
Then, before I thought to ask for a ride, anywhere, he drove on. I froze, convinced every branch and twig I saw on the path before me was a king cobra.

Pan told me afterwards that I needed to be especially careful this time of year. The temperature here on the edge of the tropics was just starting to rise and snakes were beginning to come out in the evenings to lie in open paths warmed by the sun.

Rachel would later tell me it snowed again in Boston and that sounded pretty nice to me.

The Chicken Coop

Not far from the entrance to the Chongzuo EcoPark there is a collapsing cinder block building that once served as the living quarters for biologist Pan Wenshi and his students.
I’ve seen animal enclosures in Chinese zoos that are nicer than this.

The building—an abandoned army barracks—had no running water, no electricity, no door, and a gaping hole in one wall. Pan’s bed, shown here, was a thin wicker mat laid over a row of boards. Stumps and logs were used for seats and benches. Field notes were compiled by candlelight, and when it rained, water flowed into the building.
In 2000, the county government took pity on Pan and, to honor what he'd done for surrounding villages, they spent $1 million on park improvements, including a rather architecturally inspired research facility and living space.
Until recently, the cinder block building and its Spartan furnishings served as a museum of the not-so-good-ol’ days of '96 to '00. Since my last visit, it received a long overdue conversion to its current use; a chicken coop.

Happy St. Pat's


Happy St. Patty’s Day from the PRC. I took a break from monkeying around in Chongzuo to spend a couple days in Yangshuo, China.
Yangshuo was a once gorgeous, now overrun mountain town on the Li river in southern China that has been a backpacker mecca since us laowai started descending on the country in droves in the 1990s.
The place is by no means the quiet retreat it once was, but anyplace serving the pride of St. Jame's Gate on March 17 works for me.
I spent the evening with Paul, an Englishman, and Joe, a local kid all of 10 years old.
Paul has taught English here for the last three years. He makes close to $1000 a month teaching business English in one of Yangshou’s many private schools. At this pay, he says he lives well; enough to eat out each night at the many restaurants catering to foreign tourists. He says he can’t stomach the local food, but he has a Chinese girlfriend and says the weather here beats dreary ol’ England any day.
Paul can’t stay long though as it’s “quiz”, or trivia, night at another nearby pub.

Joe is friend of Paul’s and, based on his English skills, I get the feeling this isn’t his first night hanging out at The Alley Bar. When Paul called him on his lack of green, he ran home and put on the sweater seen here. –When I ask Joe what St. Patty’s is all about, he says it’s when people wear green and drink stuff from Ireland. He says there is more to it than that, but he can’t remember the rest.
Joe first learned English from a Australian and does a wicked rendition of Crocodile Dundee's “that’s not a knife, this is a knife”.
His favorite sport is rollerblading.
“I get nice air,” he says.

Out of the blue, Joe hits me with the following riddle.
“Who is too rich?” he asks.
“Bill Gates,” I counter knowing China’s obsession with the world’s richest man.
“No, a river; it has banks on both sides.”
I go to give the kid a high five but he counters with “down low”, and then, withdrawing his hand, “too slow.”
Something tells me that of the two of them, Joe has the better gig.

King Cobra

I could see moving to Chongzuo--the weather is nice enough, the food is delicious, and the wildlife can't be beat--if it weren't for the snakes.

The reserve's walking paths are lined with billboards warning visitors of king cobras and urging them to stick to the main paths. Like most people, though, I tend to take warning signs aimed at tourists with a grain of salt.

But just to be safe, I did some Googling the other day to find out just what these snakes are all about.

A children's educational website informs me that;
-The king cobra holds a record length of 5.58 m (18.3ft) for a venomous snake.
-It has a head as big as a man’s hand and can stand tall enough to look you straight in the eye.
-the king’s venom is actually less lethal than a common cobra’s. However, the king makes up for it by delivering more venom per bite...enough to kill an elephant or 20 people.

"Tigerhomes" notes;
-Nearly ALL snakes will avoid man…there are however snakes known to aggressively attack man such as the King Cobra of Southeast Asia…

Medicine On-Line weighs in with;
"The most common and earliest symptom following snake bite is fright, particularly of rapid and unpleasant death. Owing to fright, a victim attempts 'flight' which unfortunately results in enhanced systemic absorption of venom. These emotional manifestations develop extremely rapidly (almost instantaneous) and may produce psychological shock and even death."

And here, again from Medicine On-Line, is the kicker;

"On an average - cobras and sea snakes result in about 10% mortality [28]-ranging from 5-15 hours following bite."

I don't think I'll be straying from any paths again anytime soon...

Bulbuls, Wagtails, and Great Tits!

There is a saying about the people of southern China that they eat anything with four limbs except tables, anything that flies except airplanes, and anything that swims except ships.
Perhaps, but birding in southern China's Chongzuo EcoPark is nonetheless amazing!
Noisy flocks of red-whiskered bulbuls are found in spades in the reserve’s trees and tall grass. The birds remind me of the Steller's jays that steal French fries off the plates of unwary diners at Nepenthe in Big Sur, California.
The following images—courtesy of the Peking University Chongzuo Biodiversity Research Institute—are all birds I’ve seen here this past week.

Dr. Pan's Secret Lair



At first glance, the Chongzuo EcoPark, where biologist Pan Wenshi studies white-headed langurs, appears as timeless as a Chinese landscape painting. Rugged karst peaks shoot straight out of rice paddies and sugar cane fields tended by villagers and their water buffalo. It's a scene that seems little changed for thousands of years.

The reality, however, is much more interesting.



The Chongzuo EcoPark is a former military base that was in the process of being decommissioned when Pan first arrived thirteen years ago.
Few signs of the area’s military past remain except for a massive munitions storage depot carved into the middle of one of the reserve’s mountains.

Six-inch-thick steel reinforced cement doors guard the entrance to the now abandoned depot, but much of the inside remains a natural limestone cave.

On one side of the mountain the cave opens to a cliff face about 70 meters above the valley floor where a langur family roosts most nights. Pan's assistants—LiJun, JinTong, and Lin—recently drilled a couple of cameras into the cliff face for some close up observations.

The Chinese biologist is fascinated by sociobiology, the theory that certain social behaviors—such as the practice of infanticide by male langurs—are evolutionarily advantageous.

With these cameras—which connect to a tent-enclosed-desktop inside the cave—he hopes to unlock the secrets of the animal's monkey business.

Back in Chongzuo

I wrote a story last fall on Pan Wenshi—China's founding father of conservation biology—and the white headed langur, an endangered monkey he’s spent the past decade trying to save.

At the time, Pan told me I really should come back in late winter when the year’s newborns still have their bright, canary yellow fur. I knew that Pan and his students also do an annual census of the langurs through the winter months, so when the chance came for me to make a return visit, I jumped on it.


I’m now mid-way through a two-week stay at the Chongzuo Eco Park, a 24-square km nature reserve a stone’s throw from the Vietnam border in southern China. The very phrase Chinese-nature-reserve may sound like a complete contradiction of terms, but this tiny island of biodiversity—in a country that is admittedly otherwise choking on its own pollution—is absolutely breathtaking.

When Pan arrived here 13 years ago, locals were well on their way to poaching the last remaining langurs, felling what was left of their forest habitat for firewood, and blasting their mountain home into limestone quarries.

Over the past decade, however, he’s had phenomenal success working with surrounding villages to help bring them out of poverty and to foster in them an interest in wildlife protection. The end result has been rapid reforestation within the reserve and a five-fold increase in the langur’s population--including one really cute newborn that we’ve been watching the past few days.

More Bad News for The Big 3


The amount of time the Big 3 Automakers have to get their act together on energy efficient transport just got a lot shorter.

On Monday a Chinese automaker began selling the world's first mass produced, plug-in-electric vehicle. The car, The F3DM by BYD—Build Your Dream—sells in China for $22,000 and gets 62 miles on battery-only power. The Volt, GM’s plug in hybrid will cost twice as much, get a third fewer miles to the battery, and won’t come out for another two to three years.

Interestingly, BYD rose from the ashes of a bankrupt state-owned auto company it purchased in 2003; recession be damned, let the Big 3 fail if they must so that someday they, or their successors, might make something relevant.

Why We Should Let the Big Three Fail

ƒ
[This blog originally appeared in New Scientist. See the original here.]

The second attempt at a federal bailout for the Big 3 US automakers fell apart early this morning when their union refused to trim their workers' rather cushy benefits packages.

I say good riddance. Let the dinosaurs die. It's time for auto industry version 2.0.

One alternative getting a lot of attention recently is Better Place, a Silicon Valley start-up with a business model that could quickly turn the automotive industry on its head.

Basically, it's a refueling system for all-electric vehicles that, if successful, would lead to a complete gutting of the internal combustion engine.

Better Place doesn't sell cars; rather, it sets up a national grid of refueling stations, ideally powered by renewable energy. Drivers swap out their drained batteries for fresh ones at their stations in a matter of minutes and pay Better Place by the mile, like buying minutes for a cell phone.

Israel, Denmark, Australia, and, as of last week, Hawaii are all on board. Renault-Nissan will provide the cars with the easy-to-swap batteries, and Japan is testing the company's stations for a remake of their transport system.

Tom Friedman plugged this new model earlier this week - and dissed what was then a likely bailout for the Big 3 - in an editorial for the New York Times saying:

"Our bailout of Detroit will be remembered as the equivalent of pouring billions of dollars of taxpayer money into the mail-order-catalogue business on the eve of the birth of eBay... into the CD music business on the eve of the birth of the iPod and iTunes... into a book-store chain on the eve of the birth of Amazon.com and the Kindle... into improving typewriters on the eve of the birth of the PC and the Internet."
The Better Place model may be a part of the solution, but until heavy, steel-body autos go on a serious diet, battery-driven cars are going to be prohibitively expensive.

Amory Lovins of the Rocky Mountain Institute gave a great talk at Harvard last week on Hypercars or ultralight vehicles made of advanced composites (that is, carbon fibre instead of steel) that, by virtue of their light weight, are 3-5 times more fuel-efficient.

Advanced composite car ideas have been batted around for years: GM did a one-off concept car back in 1992, but it seems no one has been able to get the economics right for mass production. Until, perhaps, now.

This summer, a Japanese paper reported that Nissan, Honda, and Toray - the largest carbon fibre manufacturer in the world - are coming together with the goal of making vehicles 40% lighter than today's models.

Last week I proposed giving the Big 3 whatever they asked for so long as the money was tied to significant CAFE standard increases. Now, I'm taking it back. The automotive industry is changing too quickly and GM, Ford, and Chrysler are too far behind.

I say if the US is going to compete in a new, fuel-efficient world, it will be with scrappy start-ups that aren't tied to 20th-century pensions. What do you think?

Chu On This!

[This story originally appeared in New Scientist. See the 0riginal Here.]

"Chu is the man!" "Chu gets it!" "Chu is hardcore!"

The eco-blogosphere is caught in an orgiastic frenzy over the pending announcement of Nobel laureate and Lawrence Berkeley National Lab director Steven Chu as US energy secretary.

So what's all the excitement about?

First, Chu would be the first person with a Nobel Prize in science to ever serve in the cabinet of a US president. The only other Nobel laureate in such a position was US Secretary of State Henry Kissinger, who shared the Nobel Peace Prize in 1973.

But what makes Chu "hardcore" is the full-on assault he's launched against climate change since taking the helm of Lawrence Berkeley in 2004.



His homepage says he is on a "mission" to make the national lab "the world leader in alternative and renewable energy research, particularly the development of carbon-neutral sources of energy".

In the past four years, he's formed some cutting-edge energy science centres, including the Joint BioEnergy Institute and the Energy Biosciences Institute. One of them, Helios, will draw on synthetic biology, a discipline that aims to rewrite the basic operating instructions of living cells, to produce new sources of clean energy.

In 2007, Chu co-authored "Rising Above the Gathering Storm", a report put out by the National Academy of Sciences that called for an energy agency similar to the Defense Advanced Research Project Agency (DARPA) as a way to fund developments in renewable energy.

The same year, he co-chaired a report commissioned by the governments of China and Brazil outlining steps they could take toward a sustainable energy future. With Chu, who is a Chinese-American researcher and a foreign member of the Chinese Academy of Sciences, heading the DOE, I wouldn't be surprised to see further collaborations on this front in the coming years.

The only possible blemish in Chu's eco-career was sealing the deal on a $500 million biofuel development handout from oil giant BP for the national lab, UC Berkeley and the University of Illinois that some felt would compromise the institutions' academic integrity.

Check out a video of Chu speaking at the National Clean Energy Summit in August. He seems like a bit of a numbers wonk, but is adamant about energy efficiency and clean energy research and development. Who better to lead the world's biggest assemblage of scientists developing renewable power?

It's Beginning To Feel Like 1980 Again


[Some great historical perspective on the Big 3 Bailout by Elizabeth Kolbert in the Talk of The Town in this week's New Yorker. See the top of the story below. Kolbert gets after Obama for not taking a strong stand on the issue but then fails to do so herself. I say give the Big 3 everything they want, but this time break the boom-bust-cycle by tying the money to a significant CAFE standard increase.]

The Secretary of Transportation’s report to Congress begins on a dark note. “Over the past year, the domestic auto industry has experienced sharply reduced sales and profitability, large indefinite layoffs, and increased market penetration by imports,” it states. “The shift in consumer preferences towards smaller, more fuel-efficient passenger cars and light trucks . . . appears to be permanent, and the industry will spend massive amounts of money to retool to produce the motor vehicles that the public now wants.” The revenue to pay for this retooling, though, will have to come from sales of just the sort of cars that the public is no longer buying—a situation, the report observes, bound to produce “financial strain.”

“To improve the overall future prospects for the domestic motor vehicle manufacturers, a quality and price competitive motor vehicle must be produced,” the report warns. “If this is not accomplished, the long term outlook for the industry is bleak.”

The Secretary’s report was delivered to Congress in 1980, a year after what may soon become known as the first Chrysler bailout... --Get the full story here. Copyright © 2008 CondéNet
