Dry Weather May Mean Less Lyme Disease

tick life cycle Over the past few decades, black-legged tick populations have grown relentlessly. These are the ticks that carry Lyme disease, and so what was once a novelty illness has become a rite of passage for many. It’s probably safe to say that by now everyone reading this knows someone who’s had the disease, if they haven’t had it themselves.

But some years are worse than others when it comes to Lyme disease infection rates, so the obvious question is: what causes this? Part of the answer involves the number of deer and small mammals around. There’s been elegant science done that establishes a neat connection between Lyme disease rates and good acorn years. The oaks produce a good crop, which causes a spike in the mouse and chipmunk populations the next year, and then a surge in human Lyme disease cases a year after that. » Continue Reading.

Eastern Musk Turtle: A Stinkpot’s Aposematic Stink Screen

musk turtle I have always admired turtles and their armored ways; how they bask in the sun and retreat when the world is too much. Last summer, through the perseverance of a nine-year-old boy, I found myself holding a small, golf-ball-sized turtle. It had a pointed snout that had two white lines stretching above and below its eye and an olive-brown carapace with a garden of algae growing on it.

Evan had captured this treasure from a local pond. We were using dip nets and strainers and our trays were already filled with dragonfly nymphs, aquatic snails, log cabin caddisfly larvae, and diving beetles. Intent on catching the silver-scaled minnows that schooled around our feet, Evan stalked the edge. He was like a great blue heron, his net like a bill, poised high and ready for a quick jab into the water. He caught two minnows and then made this lucky scoop, pulling up the small brown turtle. Our trays were forgotten as everyone crowded around. » Continue Reading.

Paul Hetzler: More Blissful Ignorance, Please

It’s a rare blessing to have a job I absolutely love, but it’s not all roses. Although some of it is, literally, roses. All too often it is my dubious honor to bring to public awareness a new invasive pest or disease, and history has not always been kind to the bearers of bad news.

There is an old saying that knowledge is power, but there is another one that ignorance is bliss, and some days I’d be happy to trade some alleged power for a little bliss. » Continue Reading.

Mallards: A Dissolute Dabbler’s Rise and Decline

mallard ducks Robert McCloskey’s Make way for Ducklings is one of my favorite childhood books. I loved the way Mr. and Mrs. Mallard interacted, their seemingly endless search for the perfect nesting place, the description of classic Boston neighborhoods, and the whimsical names of their eight ducklings.

Not until I started reading the story to my own children, several years ago now, did I notice Mr. Mallard ditches Mrs. Mallard after the ducklings hatch, leaving her to tend to eight kids on her own, amid the dangers of snapping turtles and Boston traffic.

It turns out Mr. Mallard, with his handsome green head, dapper blue wing patches, and charmingly curled tail can be a bit of a scamp; male mallards will mate with just about any feathered thing that floats on water. And they’re not always nice about it. » Continue Reading.

Stabilimenta: Northeastern Spider Silk Web Decoration

spider web When I was little and tagging along when my dad tended his vegetables, I would sometimes find large black and yellow garden spiders. They were beautiful, and I noticed they had a curious trait: they often added a bright white decorative zigzag to their webs. I always wondered why, if a spider web is meant to catch insects unawares, these spiders would go to such effort to make their webs more visible?

To answer this question, I recently spoke with Dr. Todd Blackledge, who researches spider silk and the web decorations of garden spiders. » Continue Reading.

Gregarious Great Blue Herons

blue herons Years ago, friends and I spotted a group of huge nests high in the trees along the edge of a large pond: a great blue heron rookery. From across the water (a respectful distance to avoid disturbing the birds), we observed the goings-on through our binoculars. Adult herons flew in and out of the colony, their long necks and heads folded back onto their shoulders in an S-shape, wings beating slowly, long legs trailing behind.

As a parent approached its nest, the young stood up eagerly, jostling each other and clamoring for food. Alighting on the stick platform, the adult quickly inserted its long beak into each nestling’s throat, and with a pumping motion, regurgitated a nutritious soup, which likely included fish, crayfish, or frogs. » Continue Reading.

New Hampshire’s Ancient Volcano

Ossipee Ring DikeNorth of Concord and south of the White Mountains is an estate romantically named Castle in the Clouds. Reclining on the patio there on a pleasant spring afternoon, you might enjoy the sun as well as the view. While it’s a beautiful view today, 122 million years ago it would have been a lot more exciting: you would have been staring at an active volcano.

Some articles about the Ossipee Mountains compare the former volcano that created them to Mount Vesuvius or Mount Fiji, attributing to it an eruption ten times bigger than Mount St. Helens’ last explosion. Nelson Eby, Professor of Geosciences at the University of Massachusetts, Lowell, is less sure. “We don’t actually know that there was a big volcano,” said Eby; “it might have been small. What we do know is that however big the original volcano was, it ultimately collapsed on itself.” » Continue Reading.

A Slow Start for Snapping Turtles

snapping turtle One moonless May evening, my husband and I walked down to our local pond, flashlights in hand, to look for toads. We were delighted to discover hundreds of them, floating, darting, and jockeying for position in an explosion of courtship. Their surround-sound trills left our ears ringing.

The toads were frenzied, focused only on each other, and highly concentrated in one small, shallow section of the pond, which prompted my husband to wonder if they weren’t awfully vulnerable to predators that way. » Continue Reading.

Tent Worms: Eastern Tent or Forest Tent?

Forest Tent CaterpillarLike a B-grade horror film, they’re back. Writhing en masse, draping cobwebs, and raining tiny “peppercorn” poop onto us, tent caterpillars have returned. Known variously as tent worms, army worms, and a host of other names not suitable to print, there are actually two species of tent caterpillars. » Continue Reading.

What the… Adirondack Turkey Vultures

“Mom, there’s a really big crow in the compost,” my son said one day early this spring, followed closely by, “Wait. What is that bird? It’s huge!”

I peeked out the back window to find a bird, huge indeed, a red head atop of cloak of dark feathers, sitting on a corner post of the garden fence, peering into the compost heap. Two others perched behind the garden, high in a tall white pine tree. The red head, naked of feathers, easily gave the birds away as turkey vultures. While we see these vultures often during the warmer months, soaring in circles high in the sky, we’d never seen them up close. » Continue Reading.

Intense Tent Caterpillars

eastern tent caterpillarThey hang around on finely spun strands of silky string; blue-black caterpillars parachuting ever-so-slowly to earth, landing in yards, crawling around on decks and porches; even finding their way into homes. Over the past few weeks, several people have asked me about them. Some have been coping with large numbers of them. And one person asked if they were the same worms that make their webs in apple trees.

They are not. They are similar, though. Both are hairy. Both are dark colored. Both grow from less than one-eighth of an inch to two inches or larger over a six to eight week period. And both are tent caterpillars. Beyond that, they’re clearly different. » Continue Reading.

Motorists: Be Alert for Turtles Crossing Roadways

painted turtleThe New York State Department of Environmental Conservation (DEC) is reminding the public that the state’s native turtles are on the move through June, seeking sandy areas or loose soil to lay their eggs.

In New York, thousands of turtles are killed each year when they are struck by vehicles while migrating to nesting areas. New York’s 11 native species of land turtles are in decline, and turtles can take more than 10 years to reach breeding age. The reptiles lay just one small clutch of eggs each year, which means the loss of a breeding female can have a significant effect on the local turtle population. » Continue Reading.
