Animal migration is a magnificent sight: a mile-long blanket of cranes rising from a Nebraska river and filling the sky; hundreds of thousands of wildebeests marching across the Serengeti; a blaze of orange as millions of monarch butterflies spread their wings to take flight. Nature’s great migrations have captivated countless spectators, none more so than premier ecologist David S. Wilcove. In No Way Home, his awe is palpable—as are the growing threats to migratory animals. We may be witnessing a dying phenomenon among many species. Migration has always been arduous, but today’s travelers face unprecedented dangers. Skyscrapers and cell towers lure birds and bats to untimely deaths, fences and farms block herds of antelope, salmon are caught en route between ocean and river, breeding and wintering grounds are paved over or plowed, and global warming disrupts the synchronized schedules of predators and prey. The result is a dramatic decline in the number of migrants. Wilcove guides us on their treacherous journeys, describing the barriers to migration and exploring what compels animals to keep on trekking. He also brings to life the adventures of scientists who study migrants. Often as bold as their subjects, researchers speed wildly along deserted roads to track birds soaring overhead, explore glaciers in search of frozen locusts, and outfit dragonflies with transmitters weighing less than one one-hundredth of an ounce. Scientific discoveries and advanced technologies are helping us to understand migrations better, but alone, they won’t stop sea turtles and songbirds from going the way of the bison or passenger pigeon. What’s required is the commitment and cooperation of the far-flung countries migrants cross—long before extinction is a threat. As Wilcove writes, “protecting the abundance of migration is key to protecting the glory of migration.” No Way Home offers powerful inspiration to preserve those glorious journeys.

Das erste Lehrbuch zur Ökologie der Wirbeltiere Der Wolf frisst einen Elch, der Luchs ein Reh und der Habicht einen jungen Waldkauz. Was bedeutet das für die Bestände der Beutetiere? Vögel und Säugetiere zeigen als endotherme Wirbeltiere viele Gemeinsamkeiten in ihrer Biologie. Ausgehend von den theoretischen Grundlagen der Ökologie und mit einem konsequent evolutionsbiologischen Ansatz behandelt «Ökologie der Wirbeltiere» die Ernährung unter ökophysiologischen und verhaltensökologischen Aspekten, die Fortpflanzung, die räumliche Ökologie auf allen Skalenebenen, Wanderungen, die Populationsbiologie sowie die Interaktionen zwischen Arten, nämlich Konkurrenz, Prädation und Parasiten, und schließt mit einem Kapitel zur Naturschutzbiologie. Die theoretischen Grundlagen sind stets mit den aktuellen empirischen Befunden verknüpft; diesen wird ein großes Gewicht beigemessen. Dieser Titel ist auf verschiedenen e-Book-Plattformen (Amazon, Apple, Libri, Thalia) auch als e-Pub-Version für mobile Lesegeräte verfügbar.

This E-ssential is a three-part series that covers John Davis's epic journey from Florida to Maine. In 2011, with support from the Wildlands Network, Davis traveled 7,600 miles in 10 months from Florida to Maine by foot, bicycle, skis, and canoe/kayak. His extensive travels were motivated by wanting to answer the question “Is it possible in the twenty-first century to identify and protect a continental-long wildlife corridor that could help to protect eastern nature into the future?” John paints a vivid picture of the physical challenges of the trek, such as climbing the highest point in South Carolina with a heavily loaded bike and trying to consume the 8,000 calories per day he needed to fuel himself for the journey. As readers adventure with Davis, they will also share his evolving understanding of what it would take to implement an Eastern Wildway. Eastern wildlife, both seen and unseen, from Florida panthers to North Carolina’s red wolves to the ghosts of cougars farther north, are the real focus of this adventure as John explores how such wildness can coexist with human development in the most populated regions of the United States. The science and conservation of large-scale connectivity are brought to life by his travels—offering unique insights into the challenges and opportunities for creating an Eastern Wildway. This is a must-read for enthusiasts of hiking narratives, as well as professionals and students interested in issues related to large-scale connectivity. Compelling photographs and other graphics complement John’s fascinating story.

Conservation of Tropical Birds has been written by four conservation biologists whose expertise spans all the tropical regions of the world. It is the first book to cover all the major issues in tropical bird conservation. Current problems faced by tropical bird conservationists are summarised and potential solutions outlined based on the results of case studies. Birds are key indicators of ecosystem health, and such a well-studied group of organisms, that they provide an excellent lens through which to examine global conservation problems caused by phenomena such as climate change, declines in ecosystem services, habitat loss, fires, overexploitation, and invasive species. Therefore, the book also provides an engaging synopsis of the general issues in conservation and the problems faced by other wildlife. This book serves as an important resource and companion to all people interested in observing and conserving birds in the tropics and elsewhere.
