Tree Biology

There are redwoods in California that were ancient by the time Columbus first landed and pines still alive that germinated around the time humans invented writing. There are Douglas firs as tall as skyscrapers and a banyan tree in Calcutta as big as a football field. From the tallest to the smallest, trees inspire wonder in all of us, and in The Tree, Colin Tudge travels around the world - throughout the United States, the Costa Rican rain forest, Panama and Brazil, India, New Zealand, China, and most of Europe - bringing to life stories and facts about the trees around us.

In Tree Thieves, Lyndsie Bourgon takes us deep into the underbelly of the illegal timber market. As she traces three timber poaching cases, she introduces us to tree poachers, law enforcement, forensic wood specialists, the enigmatic residents of former logging communities, environmental activists, international timber cartels, and indigenous communities along the way.

The biggest redwood trees are over 1,000 years old, rising more than 35 stories in what's left of the once-vast, ancient redwood forest. Believed to be impossible to ascend, these majestic giants have remained unexplored until recently, when a tiny group of daring botanists and amateur naturalists discovered a lost, dangerous, and hauntingly beautiful world high above California.

Several years ago, ecologist Lauren E. Oakes set out from California for Alaska's old-growth forests to hunt for a dying tree: the yellow-cedar. With climate change as the culprit, the death of this species meant loss for many Alaskans. Oakes and her research team wanted to chronicle how plants and people could cope with their rapidly changing world. Amidst the standing dead, she discovered the resiliency of forgotten forests, flourishing again in the wake of destruction, and a diverse community of people who persevered to create new relationships with the emerging environment.

In the mid-1970s, scientists began using DNA sequences to reexamine the history of all life. Perhaps the most startling discovery to come out of this new field is horizontal gene transfer (HGT), or the movement of genes across species lines. For instance, we now know that roughly eight percent of the human genome arrived not through traditional inheritance from directly ancestral forms, but sideways by viral infection - a type of HGT. In The Tangled Tree David Quammen chronicles these discoveries through the lives of the researchers who made them.

A leaf can be a...shade spiller, mouth filler, tree topper, rain stopper. Find out about the many roles leaves play in this poetic exploration of leaves throughout the year.
