Two waterways meet in a surreal junction at Vale Summit, a small low streambed in the Appalachian forests of Maryland, surrounded by high sandy banks and the faint sound of passing traffic. Bright orange coal mine drainage from the Hoffman tunnel washes iron oxides and sulfates over rocks and tree limbs and completely distorts the little brown flow of Braddock Run, a smaller, slower but rich stream, providing a home to benthic invertebrates and young fish that the drainage cannot. Braddock Run exhibits all the attributes of a healthy stream: neutral pH, low iron levels and a diverse scatter…
Ed has a great review of a recent paper in Nature presenting new research that describes just how extensive the damage done by the mountain pine beetle in British Columbia. The culprit of the outbreak is most likely climate change since sudden drops in temperature common in northern areas like BC have historically been a check on the beetle's population; in recent years, the winters have been less intense and the beetle populations have benefited from the extension. It immediately reminded me of the extinction-themed AAAS session I attended and blogged about last year, where ecologist Jim…
The black caiman is just one of the endangered species that inhabits the Guiana Shield. Back in November, the president of Guyana, one of the poorest countries in Latin America, offered the entirety of his country's rainforest to a British-led international body in return for help with development. Jagdeo was searching for alternatives to an obvious, but morally objectionable solution. "Maybe we should just cut down the trees. Then someone would recognize the problem," said Mr Jagdeo. "But I want to think we can fulfill our people's aspirations without cutting down the trees." British…
Just read an article about the apparently widespread use of tropical hardwoods in New York City. The numbers are impressive: ...the market for Ipé wood drives much of the industrial logging of the entire Amazon, and has increased dramatically in the past 20 years. An emergent flowering tree, which peppers the canopy of the Amazonian rainforest in hues of pink, magenta, yellow and white, Ipe grows in the rainforests at densities of only one or two trees an acre. This means that vast areas of the forests are razed to the ground to feed the market for a single tree. It is estimated that, for…
Bill Moyers wrote a piece about surface mining the other day, talking about a recent change to the policy in 2006: The proposed new rule codifies the 2004 buffer zone proposals and, according to THE NEW YORK TIMES, "seems specifically to authorize the disposal of 'excess spoil fills,' a k a mine waste, in hollows and streams." THE NEW YORK TIMES in reporting the proposed changes stated: "The Office of Surface Mining in the Interior Department drafted the rule, which will be subject to a 60-day comment period and could be revised, although officials indicated that it was not likely to be…
On the way home from the mountains Sunday night, I was decelerating around one of those lovely Pennsylvanian descending hairpin curves just as a big white dog trotted casually up the slope in the middle of the road. I swerved to avoid it, fully into the opposing lane, barely missed. I swung the car around about a hundred feet down, pulling over to the side of the road. The dog had turned around, and was trotting towards my car, wagging its tail. Heather grabbed Oscar's leash and got out before I could say anything but "Careful," holding her hand out for him to sniff. It barely acknowledged…
I found this article on Reuters this morning that tries to spin old news into a fresh bit of controversy: Doctors recommend a good dose of salmon or tuna in the diet because of its benefits to the heart. But is it good for the environment? Surging demand for salmon in particular has been spurred in part by numerous studies touting the health benefits of omega-3 fatty acids, which are present in some kinds of fish. A study published in June in the American Heart Association journal Circulation said a diet with liberal servings of fish, nuts and seeds rich in such nutrients can help lower a…
I finally got around to reading this study from PLoS One, another paper trying to address socioeconomic influences on ecology and biodiversity. The researchers explored a possible correlation between economic inequality - the distribution of wealth - and biodiversity in the US (state by state) and several other countries. They used the Gini coefficient for measuring economic inequality. Gini coefficients are expressed in a scale from 0 to 1.0, with 0 being an area in which all families/households earn exactly the same income (perfect equality) and 1.0 being an area in which one family earns…
PETA's prez sent Michael Moore a letter last week calling him a hypocrite for being fat while promoting his new film, SiCKO, a documentary criticizing the US healthcare system. Let the fat jokes begin! Congratulations from PETA on the reviews for SiCKO. Although we think that your film could actually help reform America's sorely inadequate health care system, there's an elephant in the room, and it is you. With all due respect, no one can help but notice that a weighty health issue is affecting you personally. We'd like to help you fix that. Zing! He's sure to take the request seriously now…
I've always been conflicted about vegetarianism. I have known many vegetarians and vegans in my life and it is a lifestyle choice that I can respect for its intent. I genuinely dislike factory farming of any food product, animal or plant. We take it for granted that our supermarket shelves will be stocked with mountains of flesh for consumption, and I hate to think of all the meat that is wasted. Last night I skimmed a Facebook post fervently discussing vegetarianism. The author posted a huge list of claims, from its health benefits to supposed evolutionary ties, and I wanted to take some…

Zuska blasted some moron at SciAm for referring to our own Shelley Batts as "attractive" during his summary of Shelley's recent run in with the lawyers at Wiley over the reproduction of a research figure: Excuse me? "Seems to be attractive"? WTF??? I mean, what the f*ck does that have to do with anything in the story? Why the gratuitous mention of Shelley's appearance? Oh, I know why. Because she's a WOMAN. And women, at all times, you must remember that you are women first and foremost. Your appearance is ever and always an issue, and no matter what the hell you are ever doing - be it…
