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.

There are more than 180 exotic species in the Great Lakes. Some, such as the Asian tapeworm, have had little or no impact so far. But a handful of others - sea lamprey, alewife, spiny water flea, rusty crayfish, and more - have conducted an all-out assault on the Great Lakes and are winning the battle. Here, William Rapai focuses on the impact of these invasives. Rapai begins with a brief biological and geological history of the Great Lakes. He examines new policies and the tradeoffs that must be weighed, and ends with an inspired call for action.

John Muir, who was born in Scotland and emigrated to America in 1849, was an advocate of U.S. forest conservation and was largely responsible for the establishment of Sequoia and Yosemite national parks in California. Muir has emerged as perhaps the greatest prophet of an era which finds itself suddenly aware of the urgent need to care for our planet.

The story of the American West is the story of a relentless quest for a precious resource: water. It is a tale of rivers diverted and dammed, of political corruptions and intrigue, of billion-dollar battles over water rights, of ecologic and economic disaster. In Cadillac Desert, Marc Reisner writes of the earliest settlers, lured by the promise of paradise, and of the ruthless tactics employed by Los Angeles politicians and business interests to ensure the city's growth. He documents the bitter rivalry between two government giants to transform the West.

When a shattered kayak and camping gear are found on an uninhabited island, they reignite a mystery surrounding a shocking act of protest. Five months earlier, logger-turned-activist Grant Hadwin had plunged naked into a river in British Columbia's Queen Charlotte Islands, towing a chainsaw. When his night's work was done, a unique Sitka spruce, 165 feet tall and covered with luminous golden needles, teetered on its stump. Two days later it fell.

When painter Winslow Homer first sailed into the Gulf of Mexico, he was struck by its "special kind of providence." Indeed, the Gulf presented itself as America's sea - bound by geography, culture, and tradition to the national experience - and yet, there has never been a comprehensive history of the Gulf until now. And so, in this rich and original work that explores the Gulf through our human connection with the sea, environmental historian Jack E. Davis finally places this exceptional region into the American mythos in a sweeping history that extends from the Pleistocene age to the 21st century.

It is accepted wisdom today that human beings have irrevocably damaged the natural world. We have altered our climate, acidified our oceans, and we are in the process of causing the sixth mass extinction. Yet what if this gloomy narrative obscures a more hopeful truth? In Inheritors of the Earth, renowned ecologist and environmentalist Chris D. Thomas overturns this loss-only view of the world's biodiversity, revealing how many animals and plants have benefited from the human-altered planet.

Omega-3 fatty acids have long been celebrated by doctors and dieticians as key to a healthy heart and a sharper brain. In the last few decades, that promise has been encapsulated in one of America's most popular dietary supplements. Omega-3s are today a multi-billion dollar business, and sales are still growing apace - even as recent medical studies caution that the promise of omega-3s may not be what it first appeared.

Siamo abituati a pensare che le foreste siano statiche, che stiano lì, immobili, da sempre. Ma non è così. Semplicemente vivono, e cambiano, a un ritmo più lento del nostro. C'è, tuttavia, un momento in cui abbiamo la possibilità di apprezzarne il cambiamento, e, ironia della sorte, è proprio quando vi si abbatte una calamità o, come si dice in ecologia, un "disturbo". Che sia un incendio, un'alluvione, un'eruzione, ciò che segue non è l'estinzione totale. Al contrario.

Det brukar sägas att människan vet mer om rymden än om haven. Inte för att förolämpa Stephen Hawking och hans vänner, men eftersom vi inte vet rymdens exakta storlek går påståendet inte att bevisa. Det baseras främst på att vi skickat 12 människor till månen sedan 1969, jämfört med bara 3 till havets djupaste punkt, Marianergraven. Enligt NOAA (National Oceanic and Atmospheric Administration in the US), täcker haven 71 procent av jordklotets yta och innehåller 97 procent av jordklotets vatten.

Lothar Streblow unternahm viele Reisen im In- und Ausland, auf denen er sich mit Studien über Tiere, Verhaltensforschung und Ökologie befasste. Von diesen Erkenntnissen inspiriert, entstanden zahlreiche Radiosendungen, Hörspiele und Essays, sowie Umwelt-, Reise- und Tiererzählungen. Dabei versuchte er stets dem sachkundlichen Anspruch gerecht zu werden. In "Geister in der Nacht - Nationalpark Bayerischer Wald" begibt er sich auf die Spuren der Tier- und Pflanzenwelt im Bayerischen Wald.

Der Buchfink stimmt seinen wohlklingenden Gesang an, in der Ferne ruft ein Waldkauz, eingebettet von hohen Bäumen ruht ein Waldweiher...

Hoch oben auf dem Berg, da grasen die Kühe friedlich auf der Sommerweide, die Kuhglocken läuten, munter zwitschern die Vögel...

Der neue Hörbuch-Spaziergang mit dem Lieblingsförster der Deutschen: verblüffende Phänomene und spannende Zusammenhänge. "In unseren Genen ist das Band zu den grünen Riesen noch intakt", sagt Peter Wohlleben - und tritt in seinem neuen Hörbuch den Beweis an. Die Natur ist dem modernen Mensch nur scheinbar fremd geworden, nach wie vor verbindet ihn ein starkes Band mit ihr. Ein Beispiel? Menschliche Reaktionen auf chemische Botenstoffe der Bäume: Unser Blutdruck ändert sich nachweislich, wenn wir im Wald sind.

For three years, Jennifer Ackerman lived in the small coastal town of Lewes, Delaware, in the sort of blue-water, white-sand landscape that draws summer crowds up and down the Eastern Seaboard. Birds by the Shore is a book about discovering the natural life at the ocean's edge: the habits of shorebirds and seabirds, the movement of sand and water, the wealth of creatures that survive amid storm and surf. Against this landscape's rhythms, Ackerman revisits her own history - her mother's death, her father's illness, and her hopes to have children of her own.

From pole to pole and across decades of lived experience, National Book Award-winning author Barry Lopez delivers his most far-ranging, yet personal, work to date. Horizon moves indelibly, immersively, through the author’s travels to six regions of the world: from Western Oregon to the High Arctic; from the Galápagos to the Kenyan desert; from Botany Bay in Australia to finally, unforgettably, the ice shelves of Antarctica.

In The Ice at the End of the World, Jon Gertner explains how Greenland has evolved from one of earth’s last frontiers to its largest scientific laboratory. The history of Greenland’s ice begins with the explorers who arrived here at the turn of the 20th century. Their original goal was to conquer Greenland’s seemingly infinite interior. Yet their efforts eventually gave way to scientists who built lonely encampments out on the ice and began drilling - one mile, two miles down.Their aim was to pull up ice cores that could reveal the deepest mysteries of earth’s past.
