What's Beneath the Surface?
DNA Tells the Story

Look's Pond in West Tisbury, one of two sites sampled for eDNA analysis
At
this year’s VCS Annual Meeting approximately 100 guests learned all
about an exciting new method for sampling aquatic and marine life – and
what that technique has to say about who’s living in two of our local
bodies of water. In his presentation on environmental DNA, Rockefeller
University Program for the Human Environment Director Jesse Ausubel
shared his results from water samples collected from Look’s Pond and the
Tisbury Great Pond by VCS staffer Samantha Look. (Click here for photos from the event)
Environmental DNA (eDNA), also known as extracellular, or naked DNA, is
continually cast off by aquatic organisms. But since these DNA fragments
don’t persist long before breaking down, finding evidence of a certain
species’ eDNA is a reliable indicator that the species was recently
nearby.
As presented by Jesse at the meeting, early returns from eDNA analysis
are highly encouraging. The results are generally consistent with those
obtained through traditional sampling methods, which are often damaging
to the species being studied (and others), as well as expensive and
time-consuming. (Compare, for example, a month’s long oceanic voyage on a
research vessel with simply sending out a drone to collect water
samples to bring back to the lab).
So, without further ado, let’s take a look at the results from Tisbury Great Pond and Look’s Pond
(a small pond located up the Tiasquam River from TGP, across
State/South Road). We see completely different fish species (in blue),
which is unsurprising given the large difference in salinity. Also
interesting is that the only species the two waters had in common was homo sapiens – a find befitting our status as one of Earth’s most ubiquitous species.
Technical
note regarding the table: a DNA “read” is a distinct sequence of
nucleobases – the cytosine (C), guanine (G), adenine (A), and thymine
(T) molecules that encode information in DNA – that spans the sampling
frame of interest. The number of reads is understood to be an index of
the abundance of the species. However, one read does not equal one
animal – each animal sheds a lot of eDNA, and the amount could depend on
size, age, and recent feeding history, among other factors.

The Lighter Side of Oversized Houses
For those brave enough to peer inside the "vaguely evil" exterior and see the horrors beyond the veil, this link will take you there.
In late June, the brilliantly cruel, jovially mean-spirited blog
“McMansion Hell” finally began receiving the attention it deserves –
unfortunately, that attention was largely due to online real estate
giant Zillow suing the site’s creator Kate Wagner, along with the resulting public backlash directed at Zillow (a prime example of the “Streisand effect”).
Zillow’s suit has since been dropped after Wagner’s cause was joined by
the free speech advocacy group Electronic Frontier Foundation, who
provided legal representation, and whose notoriety multiplied the PR
backlash.
The principal targets of mockery at McMansion Hell are various crimes
against architecture (a favorite is the BTU-gobbling, CO2-spewing “Pringles Can of Shame”
three-story entryway). So at its core, it’s fundamentally more about
aesthetics than any tangible harm associated with giant houses. However,
Wagner does address the more “objective” side of the issue, especially
in point #3 here, which is the matter of concern for VCS: McMansions are bad for the environment.
Local issues with “high-impact development”
Though the expression is commonly used (even in local newspapers), on our Island the most extravagant consumers of energy and natural resources are usually not McMansions. (As judged by the technical standards of McMansion Hell,
there’s nothing “Mc” about them – they may be ostentatious, but they’re
soundly constructed, using quality materials and careful design.)
VCS has a long history of speaking out on the subject,
though progress has been limited and hard-fought at every turn. To
date, only Aquinnah and Chilmark* limit home size; however, there are
some signs of progress. Chilmark’s big house bylaw that passed easily in
2013 was similar to one rejected by the town’s voters in 1991. Further,
as fears have increased that the Vineyard could turn into yet another
previously-unique tourist destination, the salience of the issue in the
public consciousness has grown. Much credit here is due to the work of
Chilmark’s Thomas Bena, whose documentary “One Big Home” has seen great
success on an international level, while furthering a difficult
conversation here at home (see left column for upcoming screenings of
the film).
* In Chilmark it really is only the ratio of house size to lot size
that is limited, though in practice it would take a very large lot to
allow the 10,000 sq. ft. homes that are cropping up regularly in
Edgartown. |
