    They follow invisible pathways — pathways that have been followed for thousands of years — while braving hunger and treacherous conditions to reach their destination. In Circle, Jeannie Baker follows the godwit’s incredible flight, taking us over awe-inspiring scenes as the birds spread their wings above such beautiful landmarks as the Great Barrier Reef and China’s breathtaking cityscapes.

    We assumed we could control the biological productivity of salmon and 'improve' upon natural processes that we didn't even try to understand. We assumed we could have salmon without rivers." --from the introductionFrom a mountain top where an eagle carries a salmon carcass to feed its young to the distant oceanic waters of the California current and the Alaskan Gyre, salmon have penetrated the Northwest to an extent unmatched by any other animal. Since the turn of the twentieth century, the natural productivity of salmon in Oregon, Washington, California, and Idaho has declined by eighty percent. The decline of Pacific salmon to the brink of extinction is a clear sign of serious problems in the region.In Salmon Without Rivers, fisheries biologist Jim Lichatowich offers an eye-opening look at the roots and evolution of the salmon crisis in the Pacific Northwest. He describes the multitude of factors over the past century and a half that have led to the salmon's decline, and examines in depth the abject failure of restoration efforts that have focused almost exclusively on hatcheries to return salmon stocks to healthy levels without addressing the underlying causes of the decline. The book:describes the evolutionary history of the salmon along with the geologic history of the Pacific Northwest over the past 40 million yearsconsiders the indigenous cultures of the region, and the emergence of salmon-based economies that survived for thousands of yearsexamines the rapid transformation of the region following the arrival of Europeanspresents the history of efforts to protect and restore the salmonoffers a critical assessment of why restoration efforts have failedThroughout, Lichatowich argues that the dominant worldview of our society -- a worldview that denies connections between humans and the natural world -- has created the conflict and controversy that characterize the recent history of salmon; unless that worldview is challenged and changed, there is little hope for recovery. Salmon Without Rivers exposes the myths that have guided recent human-salmon interactions. It clearly explains the difficult choices facing the citizens of the region, and provides unique insight into one of the most tragic chapters in our nation's environmental history.

    Besides providing homes for a diversity of species, this spectacular forest is also vitally important to the planet: its trees clean our air, its wetlands clean our water and its existence plays an important role in slowing global climate change. In this beautifully written book, award-winning author L. E. Carmichael explores this special wilderness on a tour of the forest throughout the four seasons, from one country to another. Evocative watercolor and collage artwork by award-winning illustrator Josée Bisaillon provides a rare glimpse of one of the world's most magnificent places. With excellent STEM applications in earth science and life science, this enjoyable book aims to foster environmental awareness of and appreciation for this crucial forest and its interconnections with the entire planet. In a unique approach, the text features a lyrical fictional narrative describing the wildlife in a specific part of the forest, paired with informational sidebars to provide further understanding and context. Also included are a world map of the forest, infographics on the water cycle and the carbon cycle, a glossary, resources for further reading, author's sources and an index. This book has been reviewed by experts and was written in consultation with Indigenous peoples who live in the boreal forest region.

    Looking 50 million years into the future, this text explores the possible development or extinction of the animal world through the eyes of the time-traveller.

    Curious about what had prompted a young urban artist to suddenly embrace nature she decided to follow him for a year to find out.Observing two artists through seasonal shifts and migrations, Birds Art Life celebrates the particular madness of chasing after birds in a big city, and explores what happens when the principles of birdwatching are applied to other aspects of art and life. It looks at the ecology of urban spaces and the creative and liberating effects of keeping your eyes and ears wide open. Far from seeking the exotic, Kyo discovers joy in the birds she spots in city parks and harbours, along eaves and on wires. In a world that values big and fast, Kyo begins to look to the small, steady, slow accumulations of knowledge, and the lulls that give way to contemplation.Moving between the granular and the grand, peering into the inner landscape as much as the outer one, Birds Art Life asks how we are shaped and nurtured by our passions, and how we might come to love and protect not only the world’s natural places but also the challenging urban spaces where so many of us live.

    Instead, she loved to wander the prairie seeking wonders and filling her mind with stories.When she found herself in Athens, Greece, she plunged into reading the original versions of ancient myths--especially descriptions of the fabled griffin. As she read, an exciting idea took shape in her mind. Scholars had long treated accounts of the griffin as made-up fantasies. But to Mayor, they seemed to describe something ancient people had actually seen. What could that have been? Mayor's quest to solve that mystery led her from books to ruined temples, from museums to the graves of great tattooed warriors. Finally, after poring over formerly top secret maps, she located the forbidding desert where nomadic gold hunters once entered the lair of the griffin--and she came face-to-face with her quarry.Here is the story of Mayor's detective work, which has helped create a new science in which experts match myths and fossils and begin to see the world through our ancestors' eyes.

With each of six spreads featuring one spectacular, large pop-up as well as booklets of smaller pop-ups and text, ENCYCLOPEDIA PREHISTORICA: DINOSAURS is a magnificent display of paper engineering and creativity — an astonishing book that will be read, admired, and treasured forever.

     Chemistry is a compelling guide to a community of characters who make up everything around us.

    Leigh Calvez has spent a dozen years researching, observing, and probing the lives of the giants of the deep. Here, she relates the stories of nature's most remarkable creatures, including the familial orcas in the waters of Washington State and British Columbia; the migratory humpbacks; and the ancient, deep-diving blue whales, the largest animals on the planet. The lives of these whales are conveyed through the work of dedicated researchers who have spent decades tracking them along their secretive routes that extend for thousands of miles, gleaning their habits and sounds and distinguishing peculiarities. The author invites the listener onto a small research catamaran maneuvering among 100-foot-long blue whales off the coast of California; or to join the task of monitoring patterns of humpback whale movements at the ocean surface: tail throw, flipper slap, fluke up, or blow. To experience whales is breathtaking. To understand their lives deepens our connection with the natural world.

    An x-ray microscope would do the trick, or since we're dreaming, perhaps an Asimov-style nanosubmarine (unfortunately, neither is currently feasible). Think of the wonders we could witness firsthand: antibodies atta- ing a virus, electrical signals racing down nerve fibers, proteins building new strands of DNA. Many of the questions puzzling the current cadre of sci- tists would be answered at a glance. But the nanoscale world of molecules is separated from our everyday world of experience by a daunting million-fold difference in size, so the world of molecules is completely invisible. I created the illustrations in this book to help bridge this gulf and allow us to see the molecular structure of cells, if not directly, then in an artistic rendition. I have included two types of illustrations with this goal in mind: watercolor paintings which magnify a small portion of a living cell by one million times, showing the arrangement of molecules inside, and comput- generated pictures, which show the atomic details of individual molecules. In this second edition of The Machinery of Life, these illustrations are presented in full color, and they incorporate many of the exciting scientific advances of the 15 years since the first edition.
