Tree Biology

Trouet, a leading tree-ring scientist, takes us out into the field, from remote African villages to radioactive Russian forests, offering listeners an insider's look at tree-ring research, a discipline formally known as dendrochronology. Tracing her own professional journey while exploring dendrochronology's history and applications, Trouet describes the basics of how tell-tale tree cores are collected and dated with ring-by-ring precision, explaining the unexpected and momentous insights we've gained from the resulting samples.

Our understanding of the ‘tree of life’, with powerful implications for human genetics, human health and our own human nature, has recently completely changed. This book is about a new method of telling the story of life on earth - through molecular phylogenetics. It involves a fairly simple method - the reading of the deep history of life by looking at the variation in protein molecules found in living organisms. 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.

Carbon is everywhere. It is constantly moving between the air, water, rocks, and living things. But did you know that none of these things would exist without the carbon cycle? Or that humans have caused the carbon cycle to be out of balance? Learn more about the carbon cycle in this fascinating book.

In this book, the author provides a real-life example of the shocking revelations and aftermath of DNA investigation. Growing up as one of nine children, Stephen Anderson suspected from a young age that something was amiss. A chance accident, and a small crack in the history of his family broke open. More would come to be revealed as the author sets out on a journey to find answers to his questions. Any listener wondering what a DNA test might reveal will find here one extreme example of family secrets gone awry.

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.

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.
