Didemnum an Alien Invader
By Emma Green-Beach
The alien, invasive colonial tunicate, Didemnum contributes a strong and aggravating presence in Lagoon Pond, causing fouling problems on nearly any surface available, including shellfish in the pond. Sparked by the dramatic ecological changes Didemnum is currently causing on George’s Bank, Elaine Hoagland and Mary Carman asked us at the Martha’s Vineyard Shellfish Group to be part of a pilot project involving Didemnum and the bay scallop, Argopecten irradians. We have set up a unique experiment at our shellfish nursery on Chappaquiddick, to observe the effects of Didemnum on the settlement of bay scallop larvae. Scallop larvae were introduced to 20 sieves, half with prepared pieces of Didemnum and a control substance, and the other half with simply the control substance. The larvae were introduced during the late veliger stage of development, when they have grown a shell that is not completely developed, yet are still capable of both swimming and crawling. We will be observing the behavior of the young scallops in relation to the tunicate, and determining whether there is a significant difference between the number of scallop larvae settled on the tunicate verses the control substance. This could have larger implications of the possible affects Didemnum will have in the near future on shellfish larvae settlement in the wild, and will likely lead to more study of the invasive tunicate.

Go to the Wildlife section for an article on Didemnum entitled, Ecological Observations of Colonial Ascidian Didemnum in a New England Tidal Pool Habitat.

Emma Green-Beach, a second-year summer intern at MVSG, is assisting with the experiment under the MV Vision Fellowship she was awarded this spring, as part of the Phillip K. Evans Scholarship Foundation.

Energy Bill Adopted by House Requires Utilities to Use Renewable Power Sources
By JOHN M. BRODER
Published: August 5, 2007
NY Times

WASHINGTON, Aug. 4 — The House passed a wide-ranging energy bill on Saturday that will require most utilities to produce 15 percent of their electricity from renewable sources like wind and solar power. President Bush has vowed to veto the bill because it does nothing to encourage increased domestic production of oil and gas.

“It’s a big, big deal,” said Representative Edward J. Markey, Democrat of Massachusetts and a longtime member of the energy committee. “There has been no legislation like this for a generation.”

Live the Slow Life
Living the slow life with food as the focus is as rewarding as it is easy, and it can be done daily by each one of us. Ultimately, it is about pleasure and taste, knowledge and choice. Once we begin to take an interest in the enjoyment of food, and in finding out where our food comes from, we can begin to see the effects of these choices. When we shorten the distance—both literal and figurative—that our food travels to get to us, we are participating in the Slow Food movement. Slow Food is about coming together as a food community—connecting producers and co-producers, coming together on the farm, in the market, and at the table—to create and enjoy food that is good, clean and fair.

Climate Change Update
Scientists Describe Changes Wrought by Global Warming
By RACHEL NAVA ROHR
Vineyard Gazette

Having lived in the Midwest for a few years, Woods Hole Research Center scientist Dr. Michael T. Coe knows that global warming sounds good to some ears - it implies shorter winters and higher temperatures.

"But the devil is in the details," Mr. Coe told the full house in attendance for Rising Tide: A Global Warming Forum, held Saturday night upstairs at the Grange Hall in West Tisbury. Three scientists sat on the panel, each with his own method for measuring and predicting the effects of global warming: plant flowering and bird migration, weather trends and sea level change.

Water Update
Vineyard Haven Harbor contamination update
By David Nash, VCS Board Member

CEA, Inc., an environmental consulting firm, has submitted an IRA report on behalf of the owners of the Xtramart gas station on Beach Road. in Vineyard Haven. The owner of the station is the Drake Petroleum Company. This report, also referred to as an “Immediate Response Action” report, is required due to the historical releases of petroleum contaminants which have occurred at the gas station site and represents a continuing assessment of both the description of the plume of contamination and the various contaminants that have been identified. A unique purpose served by this particular report is an analysis of other sources of contamination and an identification of other potentially responsible parties. It also presents a better depiction of plume concentrations and contaminant constituents.

Recycling Update
Giving Bottles a Second Life
August 8, 2007
NY Times

Not long ago, we argued in this space that because America has some of the best tap water available, it is time to start thinking twice about drinking commercially bottled water. One big reason is that a lot of petroleum is required to manufacture and transport the plastic bottles, thus adding to global warming and other environmental problems. Of course, in certain circumstances bottled water is necessary. It is essential during emergencies — think Katrina — and it is certainly a better alternative when the only other drinks come loaded with calories.

What the rising use of bottled water leaves us with, however, is a huge recycling problem. Of the mountain of individual plastic water bottles created by Americans each year — including enough to hold more than seven billion gallons of water — less than one-fourth are sent to the recycling industry for a second round.

Scientists issue warning on chemical
By Marla Cone, Times Staff Writer
August 3, 2007
LA Times
Bisphenol A, a compound found in plastics, may be causing reproductive disorders, the statement says.

In an unusual effort targeting a single chemical, several dozen scientists on Thursday issued a strongly worded consensus statement warning that an estrogen-like compound in plastic is likely causing an array of serious reproductive disorders in people.

Wind Update
Nantucket Sound is a national treasure
By EDWARD M. KENNEDY
August 05, 2007
Cape Cod Times

Cape Wind advocates like to caricature their opponents as a few select landowners who care only about preserving the views of Nantucket Sound. It's a clever and convenient argument, and it's dead wrong. But I have to hand it to them. By focusing on a few seaside landowners, Cape Wind developers have managed to distract the public from the real issues raised by their proposal: Do the public waters belong to all the people, or can they be seized and exploited by private companies for financial gain?

Biodiesel Update
Cooking Up More Uses for the Leftovers of Biofuel Production
By HILLARY ROSNER
Published: August 8, 2007
NY Times

The baking tins and muffin cups lining the countertops in a corner of Ronald Holser’s cluttered laboratory were filled with curious substances resembling angel food cakes and loaves of bread. But Mr. Holser did not advise eating them. The concoctions were prototypes for biodegradable weed barriers and sticky films intended to hold grass seeds on the ground long enough to germinate.

If Mr. Holser, a research chemist, and his colleague Steven F. Vaughn, a plant physiologist, are successful, they will have found more than ecologically friendly ways to fight weeds and grow grass. They will have found innovative uses for a byproduct of the production of biodiesel fuel, glycerol. This, in turn, could help transform the biodiesel industry into something that more closely resembles the petroleum industry, where fuel is just one of many profitable products.
