Six days after giving birth, a polar bear named Aurora got up and walked away from her den at the Columbus Zoo, leaving her tiny squealing cub to fend for herself. Hours later, Aurora still hadn’t returned. The cub was furless and blind, and with her temperature dropping dangerously, the zookeepers entrusted with her care felt they had no choice: They would have to raise one of the most dangerous predators in the world by hand. Over the next few weeks, a group of veterinarians and zookeepers worked around the clock to save the cub, whom they called Nora.

This book contains the definitive evidence that the Ivory-billed Woodpecker is surviving in our modern era, two-plus decades into the 21st century. The Ivory-billed Woodpecker, Campephilus principalis, survives on the North American continent in our modern era, two-plus decades into the 21st century. Its survival is a natural history miracle. The ivorybill was considered by many to have gone extinct on the North American continent as far back as the early 1900’s. Yet it was “rediscovered”. After a short while, many lost hope and again labeled it extinct. It was rediscovered again. ...

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.

Beavers, those icons of industriousness, have been gnawing down trees, building dams, shaping the land, and creating critical habitat in North America for at least a million years. Once one of the continent's most ubiquitous mammals, they ranged from the Atlantic to the Pacific, and from the Rio Grande to the edge of the northern tundra. Wherever there was wood and water, there were beavers - 60 million (or more) - and wherever there were beavers, there were intricate natural communities that depended on their activities.

Biodiversity, the diversity of life, is not only fascinating and beautiful, it is the engine of all the world's natural cycles, and the source of many of the resources on which humanity depends. Concern about biodiversity conservation is, therefore, not merely the preoccupation of a few enthusiastic naturalists—it is the lifeline business of everybody.

Conraad de Rosner is a pioneering game ranger, working with dogs to protect wildlife against poachers – both ‘bushmeat’ poachers, who use cruel snares to trap animals, and criminal syndicates killing for rhinoceros horn and capturing critically endangered pangolins, the most trafficked animal in the world. Con’s life – constantly at risk from poachers, wildlife and even his own fellow rangers – has been saved on numerous occasions by his devoted canine companions.

From the Siberian permafrost to balmy California, scientists across the globe are working to resurrect all kinds of extinct animals, from ones that just left us to those that have been gone for many thousands of years. Their tools in this hunt are both fossils and cutting-edge genetic technologies. Some of these scientists are driven by sheer curiosity; others view the lost species as a powerful weapon in the fight to preserve rapidly changing ecosystems. It seems certain that these animals will walk the earth again, but what world will that give us? And is any of this a good idea?

The impact of an asteroid led to the extinction of the dinosaurs. Could another giant cosmic missile soon be heading our way? In Target Earth, acclaimed Dutch astronomy writer Govert Schilling provides a full account of what we know, and need to know, about all the extraterrestrial matter constantly bombarding our planet—from microscopic dust particles and space debris to massive meteorites, comets, and asteroids.

The Will of Heaven is the powerful true story of how one woman overcame a debilitating addiction - rising from the courtrooms of her past to the grass plains of Kenya as a conservation research scientist. It was there she could finally fulfill her lifelong dream of working with wild elephants.

One of the most fascinating 'discoveries' made by the Jacques Costeau expedition to the Amazon was the existence of, and the legends surrounding one of the most amazing animals on earth, the Amazon River dolphin or Boto. Of course, to natives of Amazonia the 'mermaid-like' (as described by a French explorer to the region in the 18th century) legends involving one of the friendliest dolphin species in the world were already well-known. That, and other legends and beliefs regarding the Boto became basis of very strong taboos against harming the dolphins of the Ticuna and almost all other ...

It's no secret that our planet is in crisis. Environmental threats such as climate change, pollution, habitat loss, and land degradation threaten the survival of thousands of plant and animal species. In 100 Heartbeats, Jeff Corwin provides an urgent portrait of the wildlife teetering on the brink. From the forests slipping away beneath the stealthy paws of the Florida panther, to the giant panda’s plight to climb ever higher in the mountains of China, Corwin takes you on a global tour to witness firsthand the critical state of our natural world.

The stories we usually tell ourselves about climate change tend to focus on the damage inflicted on human societies by big storms, severe droughts, and rising sea levels. But the most powerful impacts are being and will be felt by the natural world and its myriad species, which are already in the midst of the sixth great extinction. The natural Eden that humanity inherited is quickly slipping away. Although we can never really know what a creature thinks or feels, The End of Eden invites the listener to meet wild species on their own terms in a range of ecosystems that span the globe.

Each year, more than 1,000 rhinoceroses are killed - in South Africa alone. There are fewer than 18,000 white rhinos and only 5,000 black rhinos left alive in the wild. The situation with regard to this corrupt, illegal war on wildlife is clearly critical. And what are rhinos killed for? Their horns - sold in shavings as a snake-oil 'cure' for colds or impotence. The going price is $16,000 a kilogram, but a rhino's horn is simply keratin, the same material as our fingernails, with no magical, medicinal properties.

Over the last half a billion years, there have been five mass extinctions of life on earth. Scientists around the world are currently monitoring the sixth, predicted to be the most devastating extinction event since the asteroid impact that wiped out the dinosaurs. Elizabeth Kolbert combines brilliant field reporting, the history of ideas and the work of geologists, botanists and marine biologists to tell the gripping stories of a dozen species – including the Panamanian golden frog and the Sumatran rhino – some already gone, others at the point of vanishing.

The last decade has seen an explosion of urban beekeeping in the US, Canada, and Europe, a well-intentioned response to perceived threats to the global honey bee population. Many thousands of people have taken up this seemingly environmentally friendly hobby, tending backyard and rooftop hives (or paying a company to do so) and encouraging honey bees to make honey and pollinate flowers. What could be wrong with that? Quite a lot, in fact. In The Honey Trap, scientist and author Dana Church demonstrates that despite reports to the contrary, honey bees are nowhere near extinction.

Many people think wild tigers are on the road to recovery, but they are in greater danger than ever - from a menace few experts saw coming. There may be only three thousand wild tigers left in the entire world. More shocking is the fact that twice that many - some six thousand - have been bred on farms, not for traditional medicine but to supply a luxury-goods industry that secretly sells tiger-bone wine, tiger-skin decor, and exotic cuisine enjoyed by China's elite.

The Monarch Butterfly Migration focuses a wider lens on the effects of climate change and the tensions between advocacy and scientific accuracy. This book reminds us to notice the natural wonders in our own backyards.

Ivory's Ghosts is the first comprehensive, contemporary look at the world's most treasured organic material, ivory. Using a wide range of historical and firsthand reportage, John Frederick Walker tells the astonishing and sometimes savage story of ivory's enormous impact on both human history and that of its most important source: the majestic African elephant.

Eighteen years ago, Stanford MBA Michele Raffin pulled off the road to help an injured dove, a momentary impulse that ignited in her a fervent commitment to saving vulnerable bird species. Today, her suburban home plays host to Pandemonium Aviaries, one of the largest avian rescue sanctuaries and endangered breeding facilities in the country, with a maze of 54 individual aviaries that house over 40 species, 14 of which are listed as threatened with extinction.

Once a killing ground for whalers hunting a leviathan they called the "devilfish," the San Ignacio Lagoon in Baja, Mexico, is now an environmental and spiritual sanctuary—the only place in the world where animals in their natural aquatic environment routinely seek out human contact. A nursery for the gray whale since before recorded history, the lagoon and its stories, told here by James Michael Dorsey, illuminate the magic of human connection to animals, and what those bonds teach us about ourselves and our purpose on this shared planet.
