One of the world's largest and oldest organisms is an 80,000 year-old aspen colony covering over 106 acres. How do aspens grow so large and so old?

Ant lions, or "doodlebugs" have impressive mandibles, are adept at camouflage, and are very successful at trapping and ambushing their prey. "Field Notes" takes a closer look at these fascinating insects.

In August, 2010, my family and I watched from our backyard an unbelievable phenomenon: a single species of dragonfly, individually numbering in the thousands, flew steadily westward across our property on the edge of town for ten magical days. Occasionally they would perch briefly – each one facing west – on the neighbor’s wire fence before continuing on.

Clark's Nutcracker

As a bird biologist who studies bird songs, I immediately recognize most sounds I come across in nature: the winnowing of a Wilson’s Snipe, the smack of a Dark-eyed Junco, the zee-chubbity-chub of a Rufous Hummingbird, just to name a few. For me it is a matrix of sound, as diverse and varied as the surrounding landscape. When I hear a strange sound in nature, I can’t give up until I determine its source.

In the great stands of old cottonwood trees along prairie rivers, chemical skirmishes are taking place between beavers, cottonwoods, and a certain species of beetle. Beavers gnaw on the trees; the trees fight back with toxic compounds; and the beetles move in to feast on the toxins. But in this apparent conflict, all three species benefit.

Next time you’re out exploring and hear the sounds of a mechanical disaster, don’t call the National Enquirer to report an alien landing. Pull out your binoculars. You might just catch a glimpse of a yellow-headed blackbird singing his song.

Fireweed: A Colorful Reminder Of Change

On a backpacking trip two summers ago, a group of fellow students and I started our trek across the Bob Marshall Wilderness on the West Fork of the Teton River. Much of this area had burned in a wildfire a few decades ago, but the landscape was far from barren. Beneath the smooth, branchless trees, fireweed was growing in bright and colorful abundance.

"What exactly is a weed? This can be a tricky question to answer. A plant that is nurtured and cultivated by one gardener may be yanked out unapologetically by the next, in favor of something preferable. It seems that a weed to one person can be a prized plant to another.
