Funny, scary, and touching true stories from Yellowstone wildlife photographers, rangers, guides, and trackers who've accidentally come face-to-face with grizzly bears and bison, who've camped out in -70 degree temperatures, and much more. From a Wall Street Journal best-selling author and wildlife photographer whose award-wining Yellowstone imagery is displayed in the Smithsonian.

Before men ruled the earth, there were wolves. Once abundant in North America, these majestic creatures were hunted to near extinction in the lower 48 states by the 1920s. But in recent decades, conservationists have brought wolves back to the Rockies, igniting a battle over the very soul of the West. With novelistic detail, Nate Blakeslee tells the gripping story of one of these wolves, O-Six, a charismatic alpha female named for the year of her birth.

In Decade of the Wolf, project leader Douglas W. Smith and acclaimed nature writer Gary Ferguson describe the journey of 31 Canadian gray wolves that were released in 1995 and 1996 into Yellowstone National Park and the people who faithfully followed them. The wolves have not only survived but completely changed the ecosystem, spilling a fresh measure of wildness across the world's first national park.

When Rick Lamplugh reports for work at the historic Lamar Buffalo Ranch on New Year's Eve, he has one goal: to learn as much as possible about the ecology of the Lamar Valley and how wolves fit in. He has three frigid months to explore on skis and snowshoes, to observe with all his senses, and to listen to and talk with experts. Lamplugh's story takes you with him as he watches winter-hungry elk and bison migrate to the Lamar Valley to graze. Wolves, coyotes, and mountain lions stalk the grazers while eagles, ravens, and magpies wait to scavenge.  

In the late 1940s, a small pack of wolves crossed the ice of Lake Superior to the island wilderness of Isle Royale, creating a perfect "laboratory" for a long-term study of predators and prey. As the wolves hunted and killed the island's moose, a young graduate student named Dave Mech began research that would unlock the mystery of one of nature's most revered (and reviled) animals - and eventually became an internationally renowned and respected wolf expert. This is the story of those early years.  

Carter Niemeyer has followed wolves - and captured many - since he helped reintroduce them in the Northern Rockies in the mid-1990s. In his second memoir, Wolf Land, he takes us across the rugged West as he tracks wolves, shares in their lives, and seeks middle ground for these iconic animals, both on the land and in our hearts. 

Ex-Green Beret George Hayduke has returned from war to find his beloved southwestern desert threatened by industrial development. Joining with Bronx exile and feminist saboteur Bonnie Abzug, wilderness guide and outcast Mormon Seldom Seen Smith, and libertarian billboard torcher Doc Sarvis, M.D., Hayduke is ready to fight the power - taking on the strip miners, clear-cutters, and the highway, dam, and bridge builders who are threatening the natural habitat.

His plan was to stay in Iowa, maybe get a job counting duck, or do a little farming. But events conspired to fling Carter Niemeyer westward and straight into the jaws of wolves. From his early years wrangling ornery federal trappers, eagles, and grizzlies, to winning a skinning contest that paved the way for wolf reintroduction in the Northern Rockies, Niemeyer reveals the wild and bumpy ride that turned a trapper - a killer - into a champion of wolves.

Humankind's relationship with the wolf is the sum of a spectrum of responses ranging from fear to admiration and affection. Lopez's classic, careful study has won praise from a wide range of reviewers and improved the way books on wild animals are written. Of Wolves and Men explores the uneasy interaction between wolves and civilization over the centuries, and the wolf's prominence in our thoughts about wild creatures. 

Like their human counterparts, dogs have been getting sicker and dying prematurely over the past few decades. Why? Scientists are beginning to understand that the chronic diseases afflicting humans - cancer, obesity, diabetes, organ degeneration, and autoimmune disorders - also beset canines. As a result, our beloved companions are vexed with preventable health problems throughout much of their lives and suffer shorter life spans.

When Catherine Raven finished her PhD in biology, she built herself a tiny cottage on an isolated plot of land in Montana. She was as emotionally isolated as she was physically, but she viewed the house as a way station, a temporary rest stop where she could gather her nerves and fill out applications for what she hoped would be a real job that would help her fit into society. In the meantime, she taught remotely and led field classes in nearby Yellowstone National Park. Then one day she realized that a mangy-looking fox was showing up on her property every afternoon at 4:15 p.m. 

An enthralling account of a modern voyage of discovery as we meet the clever, social birds of prey called caracaras, which puzzled Darwin, fascinate modern-day falconers, and carry secrets of our planet's deep past in their family history.

In Hurricane Lizards and Plastic Squid, biologist Thor Hanson tells the remarkable story of how plants and animals are responding to climate change: adjusting, evolving, and sometimes dying out. Anole lizards have grown larger toe pads, to grip more tightly in frequent hurricanes. Warm waters cause the development of Humboldt squid to alter so dramatically that fishermen mistake them for different species. Brown pelicans move north, and long-spined sea urchins south, to find cooler homes. 

In a collection of gripping stories of adventure, Doug Peacock, loner, iconoclast, environmentalist, and contemporary of Edward Abbey, reflects on a life lived in the wild, asking the question many ask in their twilight years: “Was It Worth It?”

A century ago, mountain lions were vilified as a threat to livestock and hunted to the verge of extinction. Its recovery has led to an unexpected conundrum: Do more mountain lions mean they're a threat to humans and domestic animals? Or, are mountain lions still in need of our help and protection as their habitat dwindles? Mountain lion biologist and expert Mark Elbroch welcomes these tough questions. He dismisses long-held myths about mountain lions and uses groundbreaking science to uncover important new information about their social habits.
