By December, foliage season is long over for us humans, but it’s peak season under the water. Last month, as the last bus of tourists departed for home, fallen leaves accumulated in our…
The Outside Story
When Mushrooms Attack
The oyster mushroom: delicious, frequently spotted on veggie pizzas, and predatory. That's right. The hyphae of many fungi, including the oyster mushroom, attack and paralyze prey. Then,…
With Cooler Water, Better Prospects for Shad Migration?
There was a time in the waters known by the Abenaki peoples as Kwenitegok, “Long River,” when migratory fish moved in such multitudes that their backs appeared as a living bridge…
The Apple Bears
Last week, a black bear in a blaze orange collar showed up in our yard. Two cubs followed close behind. The sow paused to observe the house, then led her cubs up across our field and down into…
Fisher Families Fall Out In Fall
Along with the crisp mornings and crimson colors that signal summer’s slide into fall, there are changes occurring in the forests that go mostly unnoticed. Among them is the dispersal of…
Hunting Mushrooms: The Old Not Bold Approach
When you stumble across something purple in the forest, it’s hard not to stop in your tracks. At least it was for me on a recent hike in Thetford, when I came across three purple…
Migration Takes Guts
As an avid birdwatcher for more than 30 years, I’ve long been familiar with the big picture of songbird migration. Tiny blackpoll warblers, for instance, fly 1,500 miles from southern…
Witch’s Brooms
Harry Potter rode one during the Quidditch matches at Hogwarts. The Wicked Witch of the West zipped around on one in the Wizard of Oz. We’re talking, of course, about witch’s…
A Primordial Lake Monster
It came from the lake. It is a life form nearly as old as life itself. Living peacefully in the depths for eons, it is awakened by humankind’s abuse of the environment. It strikes out…
October Showers
We call them shooting stars, and they never fail to make us catch our breath in surprise and wonder. But they’re not stars at all. Those bright, brief streaks across the night sky are…
Zebra Mussels
Invasive species have earned their bad reputations. English sparrows compete with native birds from Newfoundland to South America. Australian brown tree snakes are well on their way to…
Black Swallowtails Have Many Disguises
It was the dotted, orangey-yellow and black stripes that stood out, drawing my son’s gaze to the edge of the sandbox. A small caterpillar clung to the goutweed, munching away on the…
See What’s in the Milkweed Patch
Eight or so years ago I collected milkweed seeds and painstakingly buried them one at a time under leaf debris at the back edge of my yard, hoping they would mature and attract more monarch…
No Easy Recovery for Bats
In 2006, I joined a team of biologists to trap bats in Vermont’s Chittenden County. We were searching for North America’s rarest bat, the Indiana bat, which had recently been…
A Thorny Problem: Multiflora Rose
Multiflora rose is not without charm; in fact, there was a time when people went out of their way to plant it. The pretty spring flowers have a sweet scent; birds nest in the sturdy branches…
Snakes and Toads Provide Garden Pest Control
Encountering a snake in the garden causes many people to shriek or even panic. Yet snakes and another often unloved creature, the American toad, are among the most effective forms of pest…
Cattails: Nature’s Supermarket
This past winter I spent three months exploring East Africa, traveling through ten different countries and covering over 8,077 miles. I was continuously impressed with how much local guides…
Bees Feel Flower Buzz
Imagine you had a power that allowed you to pick up nearby objects without actually touching them. Imagine this power could help you find and choose the best foods while shopping. Imagine you…
Bobcats
The distinctively feline tracks through the snow in our woods last winter intrigued me. They would follow the narrow ski trail a ways, then meander into the trees or, sometimes, seem to…
Keeping it Clean Downstream
In peaceful streams, aquatic macroinvertebrates such as crayfish, stoneflies, and caddisflies travel over and under submerged rocks, foraging for other invertebrates, leaves, and algae. When…
