Two thousand miles is a staggering distance for any kind of journey. But imagine making it not by car or even foot—but by fin. That’s what faces Chinook, a female king salmon, as she takes a dramatic trip to safely deliver her eggs. From the Bering Sea, up the Yukon River, and on to the Nisutlin River, A King Salmon Journey takes young readers on an engaging ride through the waters of Alaska and Canada, bringing to life the biology—and mystery—of one of the world’s most popular fish. Based on the story of a real-life Chinook, this beautifully illustrated book deftly combines science with a fast-paced tale of survival and perseverance.
"The Yukon River is 2,000 miles long and the longest stretch of free-flowing river in the United States. In this riveting examination of one of the last wild places on earth, Adam Weymouth canoes from Canada's Yukon Territory, through Alaska, to the Bering Sea. The result is a book that shows how even the most remote wilderness is affected by the same forces reshaping the rest of the planet. Every summer, hundreds of thousands of king salmon migrate the distance of the Yukon to their spawning grounds, where they breed and die, in what is the longest salmon run in the world. For the people who live along the river, salmon were once the lifeblood of commerce and local culture. But climate change and globalized economy have fundamentally altered the balance between people and nature; the health and numbers of king salmon are in question, as is the fate of the communities that depend on them. Traveling down the Yukon as the salmon migrate, a four-month journey through untrammeled landscape, Weymouth traces the fundamental interconnectedness of people and fish through searing and unforgettable portraits of the individuals he encounters. He offers a powerful, nuanced glimpse into indigenous cultures, and into our ever-complicated relationship with the natural world. Weaving in the rich history of salmon across time as well as the science behind their mysterious life cycle, 'Kings of the Yukon' is extraordinary adventure and nature writing at its most urgent and poetic"--Dust jacket.
Pacific salmon are an important biological and economic resource of countries of the North Pacific rim. They are also a unique group of fish possessing unusually complex life histories. There are seven species of Pacific salmon, five occurring on both the North American and Asian continents (sockeye, pink, chum, chinook, and coho) and two (masu and amago) only in Asia. The life cycle of the Pacific salmon begins in the autumn when the adult female deposits eggs that are fertilized in gravel beds in rivers or lakes. The young emerge from the gravel the following spring and will either migrate immediately to salt water or spend one or more years in a river or lake before migrating. Migrations in the ocean are extensive during the feeding and growing phase, covering thousands of kilometres. After one or more years the maturing adults find their way back to their home river, returning to their ancestral breeding grounds to spawn. They die after spawning and the eggs in the gravel signify a new cycle. Upon this theme Pacific salmon have developed many variations, both between as well as within species. Pacific Salmon Life Histories provides detailed descriptions of the different life phases through which each of the seven species passes. Each chapter is written by a scientist who has spent years studying and observing a particular species of salmon. Some of the topics covered are geographic distribution, transplants, freshwater life, ocean life, development, growth, feeding, diet, migration, and spawning behaviour. The text is richly supplemented by numerous maps, illustrations, colour plates, and tables and there is a detailed general index, as well as a useful geographical index.
This robust and engaging travel narrative re-creates a remarkable adventure in the summer of 1935, when Frederica de Laguna, then in her late 20s, led a party of three other scientists down the rivers of the middle and lower Yukon valley, making a geological and archaeological reconnaissance. De Laguna has based her story on her field notes, journals, and letters home. She augments this first-hand account with excerpts from the reports of earlier explorers and data published after her trip. The result is a fascinating and informative cross-cut of historical events along the Yukon River and its tributaries. Travels Among the Dena chronicles the expedition from its outfitting in Seattle and the trip by steamer and railway to Fairbanks and Nenana, through an 80-day journey on skiffs down the Tanana and Yukon rivers to Holy Cross near the coast, with side trips on the Koyukuk, Khotol, and Innoko rivers, before a one-day return flight to Fairbanks with pioneer bush pilot Noel Wien. Maps illustrate the route taken downriver, and the author’s photographs capture images of the time. The resulting volume is both a delightful addition to the literature of travel adventure in Alaska and an important contribution to the discipline of anthropology.
PNBA BESTSELLER • “A powerful and inspiring story. Guido Rahr’s mission to save the wild Pacific salmon leads him into adventures that make for a breathtakingly exciting read.”—Ian Frazier, author of Travels in Siberia Editors’ Choice: The New York Times Book Review • Outside Magazine • National Book Review • Forbes In the tradition of Mountains Beyond Mountains and The Orchid Thief, Stronghold is Tucker Malarkey’s eye-opening account of one of the world’s greatest fly fishermen and his crusade to protect the world’s last bastion of wild salmon. From a young age, Guido Rahr was a misfit among his family and classmates, preferring to spend his time in the natural world. When the salmon runs of the Pacific Northwest began to decline, Guido was one of the few who understood why. As dams, industry, and climate change degraded the homes of these magnificent fish, Rahr saw that the salmon of the Pacific Rim were destined to go the way of their Atlantic brethren: near extinction. An improbable and inspiring story, Stronghold takes us on a wild adventure, from Oregon to Alaska to one of the world’s last remaining salmon strongholds in the Russian Far East, a landscape of ecological richness and diversity that is rapidly being developed for oil, gas, minerals, and timber. Along the way, Rahr contends with scientists, conservationists, Russian oligarchs, corrupt officials, and unexpected allies in an attempt to secure a stronghold for the endangered salmon, an extraordinary keystone species whose demise would reverberate across the planet. Tucker Malarkey, who joins Rahr in the Russian wilderness, has written a clarion call for a sustainable future, a remarkable work of natural history, and a riveting account of a species whose future is closely linked to our own. Praise for Stronghold “This book isn’t just about fish, it’s about life itself and the fragile unseen threads that connect all creatures across this beleaguered orb we call home. Guido Rahr’s quest to save the world’s wild salmon should serve as an inspiration—and a provocation—for us all, and Tucker Malarkey’s exquisite book captures Rahr’s weird and wonderful story with poignancy, humor, and grace.”—Hampton Sides, author of In the Kingdom of Ice and Blood and Thunder “A crazy-good, intensely lived book that reads like an international thriller—only it’s our beloved salmon playing the part of diamonds or oil or gold.”—David James Duncan, author of The River Why and The Brothers K
Offering a viable solution to the long-standing problem of estimating the abundance of rare, clustered populations, adaptive sampling designs are rapidly gaining prominence in the natural and social sciences as well as in other fields with inherently difficult sampling situations. In marked contrast to conventional sampling designs, in which the entire sample of units to be observed is fixed prior to the survey, adaptive sampling strategies allow for increased sampling intensity depending upon observations made during the survey. For example, in a survey to assess the abundance of a rare animal species, neighboring sites may be added to the sample whenever the species is encountered during the survey. In an epidemiological survey of a contagious or genetically linked disease, sampling intensity may be increased whenever prevalence of the disease is encountered. Written by two acknowledged experts in this emerging field, this book offers researchers their first comprehensive introduction to adaptive sampling. An ideal reference for statisticians conducting research in survey designs and spatial statistics as well as researchers working in the environmental, ecological, public health, and biomedical sciences. Adaptive Sampling: Provides a comprehensive, fully integrated introduction to adaptive sampling theory and practice Describes recent research findings Introduces readers to a wide range of adaptive sampling strategies and techniques Includes numerous real-world examples from environmental pollution studies, surveys of rare animal and plant species, studies of contagious diseases, marketing surveys, mineral and fossil-fuel assessments, and more
“A necessary book for anyone truly interested in what we take from the sea to eat, and how, and why.” —Sam Sifton, The New York Times Book Review Acclaimed author of American Catch and The Omega Princple and life-long fisherman, Paul Greenberg takes us on a journey, examining the four fish that dominate our menus: salmon, sea bass, cod, and tuna. Investigating the forces that get fish to our dinner tables, Greenberg reveals our damaged relationship with the ocean and its inhabitants. Just three decades ago, nearly everything we ate from the sea was wild. Today, rampant overfishing and an unprecedented biotech revolution have brought us to a point where wild and farmed fish occupy equal parts of a complex marketplace. Four Fish offers a way for us to move toward a future in which healthy and sustainable seafood is the rule rather than the exception.
