For centuries biologists have tried to understand the underpinnings of avian migration: where birds go and why, why some migrate and some do not, how they adapt to a changing environment, and how migratory systems evolve. Twenty-five years ago the answers to many of these questions were addressed by a collection of migration experts in Keast and Morton's classic work Migrant Birds in the Neotropics. In 1992, Hagan and Johnston published a follow-up book, Ecology and Conservation of Neotropical Migrant Landbirds. In Birds of Two Worlds Russell Greenberg and Peter Marra bring together the world's experts on avian migration to discuss its ecology and evolution. The contributors move the discussion of migration to a global stage, looking at all avian migration systems and delving deeper into the evolutionary foundations of migratory behavior. Readers interested in the biology, behavior, ecology, and evolution of birds have waited a decade to see a worthy successor to the earlier classics. Birds of Two Worlds will complete the trilogy and become indispensable for ornithologists, evolutionary biologists, serious birders, and public and academic libraries.

A mountain-chain, pierced through from base to summit—a gorge four miles in length, walled in by lofty precipices; between their dizzy heights the giant stream of the Old World, the Danube. Did the pressure of this mass of water force a passage for itself, or was the rock riven by subterranean fire? Did Neptune or Vulcan, or both together, execute this supernatural work, which the iron-clad hand of man scarce can emulate in these days of competition with divine achievements? Of the rule of the one deity traces are visible on the heights of Fruska Gora in the fossil sea-shells strewn around, and in Veterani's cave with its petrified relics of saurian monsters of the deep; of the other god, the basalt of Piatra Detonata bears witness. While the man of the iron hand is revealed by long galleries hewn in the rock, a vaulted road, the ruined piers of an immense bridge, the tablets sculptured in bas-relief on the face of the cliff, and by a channel two hundred feet wide, hollowed in the bed of the river, through which the largest ships may pass. The Iron Gate has a history of two thousand years. Four nations—Romans, Turks, Roumanians and Hungarians, have each in turn given it a different name.

SCIENCE is a left-brained subject. It sees the world in mathematical models. It is all built on logic. RELIGION is a right-brained subject. It sees the world in associations. It is all built on symbolism. Misconceptions are what prevent us from reconciling the associations with the mathematical models. Once the misconceptions are revealed, the problem goes away. The teachings of Eastern Philosophy are interwoven throughout the Old and New Testaments. What they have to say explains a great deal about what the Holy Bible is trying to say to us. It reveals much of the symbolism used in religion so that it can be understood. It takes you beyond the realm of faith and into the realm of knowing. The Mayan Calendar and its apparent connection to end-time prophecy is also reviewed. The evolution of consciousness that it reveals is leading us on a very definite path. Taken collectively, evolution, split brain, Eastern Philosophy, Christianity, and the Mayan Calendar are interwoven to present a worldview that is equally fascinating and very promising.

New York Times Bestseller Finalist for the Los Angeles Times Book Prize A Library Journal Best Science and Technology Book of the Year An exhilarating exploration of the science and wonder of global bird migration. In the past two decades, our understanding of the navigational and physiological feats that enable birds to cross immense oceans, fly above the highest mountains, or remain in unbroken flight for months at a stretch has exploded. What we’ve learned of these key migrations—how billions of birds circumnavigate the globe, flying tens of thousands of miles between hemispheres on an annual basis—is nothing short of extraordinary. Bird migration entails almost unfathomable endurance, like a sparrow-sized sandpiper that will fly nonstop from Canada to Venezuela—the equivalent of running 126 consecutive marathons without food, water, or rest—avoiding dehydration by "drinking" moisture from its own muscles and organs, while orienting itself using the earth’s magnetic field through a form of quantum entanglement that made Einstein queasy. Crossing the Pacific Ocean in nine days of nonstop flight, as some birds do, leaves little time for sleep, but migrants can put half their brains to sleep for a few seconds at a time, alternating sides—and their reaction time actually improves. These and other revelations convey both the wonder of bird migration and its global sweep, from the mudflats of the Yellow Sea in China to the remote mountains of northeastern India to the dusty hills of southern Cyprus. This breathtaking work of nature writing from Pulitzer Prize finalist Scott Weidensaul also introduces readers to those scientists, researchers, and bird lovers trying to preserve global migratory patterns in the face of climate change and other environmental challenges. Drawing on his own extensive fieldwork, in A World on the Wing Weidensaul unveils with dazzling prose the miracle of nature taking place over our heads.

In the 1600s, over 350,000 intrepid English men, women, and children migrated to America, leaving behind their homeland for an uncertain future. Whether they settled in Jamestown, Salem, or Barbados, these migrants -- entrepreneurs, soldiers, and pilgrims alike -- faced one incontrovertible truth: England was a very, very long way away. In Between Two Worlds, celebrated historian Malcolm Gaskill tells the sweeping story of the English experience in America during the first century of colonization. Following a large and varied cast of visionaries and heretics, merchants and warriors, and slaves and rebels, Gaskill brilliantly illuminates the often traumatic challenges the settlers faced. The first waves sought to recreate the English way of life, even to recover a society that was vanishing at home. But they were thwarted at every turn by the perils of a strange continent, unaided by monarchs who first ignored then exploited them. As these colonists strove to leave their mark on the New World, they were forced -- by hardship and hunger, by illness and infighting, and by bloody and desperate battles with Indians -- to innovate and adapt or perish. As later generations acclimated to the wilderness, they recognized that they had evolved into something distinct: no longer just the English in America, they were perhaps not even English at all. These men and women were among the first white Americans, and certainly the most prolific. And as Gaskill shows, in learning to live in an unforgiving world, they had begun a long and fateful journey toward rebellion and, finally, independence

To go through the pages of the Autobiography of Mario Bunge is to accompany him through dozens of countries and examine the intellectual, political, philosophical and scientific spheres of the last hundred years. It is an experience that oscillates between two different worlds: the different and the similar, the professional and the personal. It is an established fact that one of his great loves was, and still is, science. He has always been dedicated to scientific work, teaching, research, and training men and women in multiple disciplines. Life lessons fall like ripe fruit from this book, bringing us closer to a concept, a philosophical idea, a scientific digression, which had since been uncovered in numerous notes, articles or books. Bunge writes about the life experiences in this book with passion, naturalness and with a colloquial frankness, whether they be persecutions, banishment, imprisonment, successes, would-be losses, emotions, relationships, debates, impressions or opinions about people or things. In his pages we pass by the people with whom he shared a fruitful century of achievements and incredible depths of thought. Everything is remembered with sincerity and humor. This autobiography is, in truth, Bunge on Bunge, sharing everything that passes through the sieve of his memory, as he would say. Mario’s many grandchildren are a testament to his proud standing as a family man, and at the age of 96 he gives us a book for everyone: for those who value the memories that hold the trauma of his life as well as for those who share his passion for science and culture. Also, perhaps, for some with whom he has had disagreements or controversy, for he still deserves recognition for being a staunch defender of his convictions.
