Invasive species prevention

Posted by earle

We went kayaking on Haunted Lake in Francestown today. The weather was about perfect for temperature although the wind came up as we headed back. It was blowing the wrong way, of course.
Along with lots of flowering water lilies, there seemed to be a lot of strange growths on the bottom of the lake. We [...]

Sustainable seafood from the Gulf of Maine

Posted by david brooks

The Gulf of Maine Institute is mounting a campaign saying that fish caught in the Gulf of Maine can be eaten without any liberal guilt (that’s not quite how they  phrase it), because stock management plans have made its harvest largely sustainable. (Here’s the Portland Press-Herald story.) It’s always hard to know how much of  [...]

Getting offspring from a super chestnut tree in N.H.

Posted by david brooks

If all goes well, this morning (Monday morning) I will accompany folks from the American Chestnut Foundation as they hand pollinate a “mother tree” found in Hudson, N.H., near the Mass. border. These trees have the blight that has virtually destroyed the American chestnut, but still flower - they have some sort of natural resistance. [...]

From the story:
“For the first time, we’ll know — did they get [...]

Examining evolution by manipulating entire islands

Posted by david brooks

New Scientist has an article (here it is) about two Dartmouth researchers doing a real-world experiment manipulating reality to see what it does to evolution - in this case, to some small lizards on some tiny Bahamas Islands. Among other things, they wrapped some islands in mesh to keep out predators, and imported predators on [...]

A play about evolution at MIT

The sound of trees’ vascular systems

Posted by david brooks

BoingBoing has a post (read it here) linking to a “bio-acoustician” who has recorded the sound that trees’ vascular systems make as they move material up and down the circulatory system - as maple trees are doing right now, much to the joy of syrup makers. From the article:
The xylem and phloem of the tree [...]

48 invasive species in Lake Champlain alone?

Posted by david brooks

The above map was taken from this blog post, which sources it to U. Vermont and Sea Grant researchers. The caption says it all: There are 48 invasive species identified in lake Champlain, and at least another 136 - 136 of them!!! - in waterways that connect to the lake, the Great Lakes, St. Lawrence Seaway and Hudson River.

I don’t know what else to say except holy cow.

Pasteurize your cider or watch it start to swell

Posted by david brooks

If you ever wonder why stuff needs to be pasteurized, the above picture is a demonstration. (It looked much better in person than in the picture.) The swollen jug on the right holds apple cider that we made with friends, which was left in the fridge for a month or so. The jug on the left is a normal jug, for comparison.

Unpasteurized cider only seems to last a week in the refrigerator before enough microbes grow to alter the taste.Then they start emitting various gaseous byproducts of digestion, which swells up the jug. I don’t know whether it ever would have burst - probably not, that plastic is pretty tough.

Incredible shrinking compost pile

Posted by david brooks

We all know that piles of stuff gets smaller as it decays, but don’t usually get to see the difference. I have a graphic example every fall, however, in my leaf pile. I’ve estimated that over the course of one year the leaf pile reduces in volume by 90%-95%, and over the following year, they reduce in volume by another 50%.
