He is also the Head Teaching Fellow for the most popular course at Harvard, “Positive Psychology,” which is taken by more than 1,000 students per semester and led by Professor Tal Ben-Shahar.  Shawn received his B.A. in English from Harvard and a Master’s from Harvard Divinity School in Christian and Buddhist Ethics. Part of his interest in positive psychology stems from a troubling fact: studies have shown that many of Harvard’s undergraduates suffer from depression at some point in their college careers.

    He had a talent for drawing and an interest in birds, and he would spend the next thirty-five years traveling to the remotest regions of his new country–often alone and on foot–to render his avian subjects on paper. The works of art he created gave the world its idea of America. They gave America its idea of itself. Here Richard Rhodes vividly depicts Audubon’s life and career: his epic wanderings; his quest to portray birds in a lifelike way; his long, anguished separations from his adored wife; his ambivalent witness to the vanishing of the wilderness. John James Audubon: The Making of an American is a magnificent achievement.

    Descriptions of each print is written by Dr. Colin Harrison and Cyril Walker, scientific officers of the British Museum of Natural History.

    But there is an important and simple step toward reversing this alarming trend: Everyone with access to a patch of earth can make a significant contribution toward sustaining biodiversity.There is an unbreakable link between native plant species and native wildlife—native insects cannot, or will not, eat alien plants. When native plants disappear, the insects disappear, impoverishing the food source for birds and other animals. In many parts of the world, habitat destruction has been so extensive that local wildlife is in crisis and may be headed toward extinction.Bringing Nature Home has sparked a national conversation about the link between healthy local ecosystems and human well-being, and the new paperback edition—with an expanded resource section and updated photos—will help broaden the movement. By acting on Douglas Tallamy's practical recommendations, everyone can make a difference.

    The journals in which the author recorded his observations, and the captivating drawings he created, form the heart of this compelling book—a personal account of an artist-naturalist’s life with owls. Angell’s extensive illustrations show owls engaged in what owls do—hunting, courting, raising families, and exercising their inquisitive natures—and reveal his immeasurable respect for their secret lives and daunting challenges.   Angell discusses the unique characteristics that distinguish owls from other bird species and provides a fascinating overview of the impact owls have had on human culture and thought. He also offers detailed scientific descriptions of the nineteen species of owls found in North America, as well as their close relatives elsewhere. Always emphasizing the interaction of humans and owls, the author affirms by his own example the power of these birds both to beguile and to inspire.

    In the preface to this book, author Keith Delaplane says of his first book on beekeeping, "Its pages opened to me a golden world of honey bees and beekeeping and guided my stumbling steps that first spring season. My story is but one of thousands who have passed through the door opened by Dadant's little book."

    The pictorial models are useful in understanding relationships. The models also abound in descriptive detail.

    Belknap's Waterproof Grand Canyon River Guide (All New Color Edition)

    During the year as they cross-country ski, hike, bicycle, canoe, and backpack into Yellowstone's grandeur, Rick digs into important controversies: the outrage over the proposed removal of grizzlies from the endangered species list; the dispute over hunting park wolves along Yellowstone's border; the debate about whether wolves help or harm the ecosystem and the economy; the fight to stop the slaughter of park bison; the overuse of the park; and their community's battle to prevent gold mining on the park's border. Rick ends the year with a stronger love for Yellowstone's grandeur, a deeper knowledge of the controversies threatening the park, and a desire to inspire readers to protect our nation's first national park.

    Humans have feared them for centuries, long considering them the assassins and pariahs of the natural world.Now, in Venomous, the biologist Christie Wilcox investigates and illuminates the animals of our nightmares, arguing that they hold the keys to a deeper understanding of evolution, adaptation, and immunity. She reveals just how venoms function and what they do to the human body. With Wilcox as our guide, we encounter a jellyfish with tentacles covered in stinging cells that can kill humans in minutes; a two-inch caterpillar with toxic bristles that trigger hemorrhaging; and a stunning blue-ringed octopus capable of inducing total paralysis. How do these animals go about their deadly work? How did they develop such intricate, potent toxins? Wilcox takes us around the world and down to the cellular level to find out.Throughout her journey, Wilcox meets the intrepid scientists who risk their lives studying these lethal beasts, as well as “self-immunizers” who deliberately expose themselves to snakebites. Along the way, she puts her own life on the line, narrowly avoiding being envenomated herself. Drawing on her own research, Wilcox explains how venom scientists are untangling the mechanisms of some of our most devastating diseases, and reports on pharmacologists who are already exploiting venoms to produce lifesaving drugs. We discover that venomous creatures are in fact keystone species that play crucial roles in their ecosystems and ours—and for this alone, they ought to be protected and appreciated.Thrilling and surprising at every turn, Venomous will change everything you thought you knew about the planet’s most dangerous animals.

    The roots of a tree indicate the sun’s direction; the Big Dipper tells the time; a passing butterfly hints at the weather; a sand dune reveals prevailing wind; the scent of cinnamon suggests altitude; a budding flower points south. To help you understand nature as he does, Gooley shares more than 850 tips for forecasting, tracking, and more, gathered from decades spent walking the landscape around his home and around the world. Whether you’re walking in the country or city, along a coastline, or by night, this is the ultimate resource on what the land, sun, moon, stars, plants, animals, and clouds can reveal—if you only know how to look!

    As our prehistoric ancestors spread throughout the globe, they began the most deadly epoch the planet's fauna have experienced since the demise of the dinosaurs. And following the dawn of the age of exploration five hundred years ago, the rate of extinction has accelerated ever more rapidly." In A Gap in Nature, scientist and historian Tim Flannery, in collaboration with internationally acclaimed wildlife artist Peter Schouten, catalogues 103 creatures that have vanished from the face of the earth since Columbus first set foot in the New World. From the colorful Carolina parakeet to the gigantic Steller's sea cow, Flannery evocatively tells the story of each animal and its habitat, how it lived and how it succumbed to its terrible destiny. Accompanying every entry is a beautifully rendered color representation by Schouten, who has devoted years of his life to this project. His portraits - life size in their original form - are exquisitely reproduced in this extraordinary book and include animals from every continent: American passenger pigeons, Tasmanian thylacines, Mauritian dodos, African bluebucks, and dozens more.
