How Do Trees Know When to Wake Up?
We take for granted that trees drop their leaves in fall and open their buds in spring, with a glorious burst of flowers and leaves. Indeed, florists know that apple branches cut in March and…
Sheep, Externalities, and the Price of Grain
We lost money on sheep this year at our farm. In the grand scheme of things, we’re in good company: farmers in New Hampshire and Vermont have been losing money on sheep for going on 180…
Endangered Species on my Windowsill
It was with uneasiness that I accepted the little African violet a friend gave me for my birthday a few years ago. I had never had any luck growing the cute little furry things. To my dismay,…
A Reprieve for Deer

Some Insects in Winter Get Super Cool

Backyard Chipmunks Living the Good Life
Each fall day he appears with a skinny face and leaves with ballooned cheeks. Over and over, he fills his cheeks and runs away to empty them. Our eastern chipmunk, it seems, is living in a…
Modern Moose Management

Shouldn’t Have Happened to a Frog
On an August day 15 years ago, eight Minnesota junior high school students on a field trip caught 22 frogs in a farm pond. At least half of the frogs had some abnormality, mostly in their hind…
Every Niche Has Its Own Species

Silverfish: Lurking in a Bathroom Near You
This afternoon, a 390-million-year-old thysanuran paid me a visit on my desk. It wasn’t really that old, just a little creature whose uninterrupted ancestry dates back at least that far.…
Stalking the Wild Brown Trout
The rod was nearly yanked from my hands as a dark shadow tore out of the shallows and attached itself to my lure. When you’re 11 years old, this can be a life-changing experience. I…
Buck Meets Doe
One of the evolutionary adjustments whitetail deer have made is to reproduce early and often. A six-year-old whitetail doe can easily become a great-great-grandmother, and she can continue to…
Hunting with the Abenaki

The Nature of Powerlines
In Pittsford, Vermont, a state-threatened sunflower nods in the breeze. Near Concord, New Hampshire, the tiny, federally-endangered Karner blue butterfly flits from one flower-spike of wild…
Arthropods Make Strange Bedfellows

Delayed Implantation (And Other Weasel-like Behavior)
In the English language, someone who overeats is called a “pig”; a coward gets labeled a “chicken.” If you raise pigs or chickens, you know that these barnyard associations are deftly…
Supercharging the Nitrogen Cycle
Our lawn is a scruffy assortment of grasses and weeds that receives zero care apart from mowing. The beleaguered grass struggles in the face of competition. However, green grass persists in…
