Delphus E. Carpenter (1877-1951) was Colorado's commissioner of interstate streams during a time when water rights were a legal battleground for western states. A complex, unassuming man as rare and cunning in politics and law as the elusive silver fox of the Rocky Mountain West, Carpenter boldly relied on negotiation instead of endless litigation to forge agreements among states first, before federal intervention. In Silver Fox of the Rockies, Daniel Tyler tells Carpenter's story and that of the great interstate water compacts he helped create. Those compacts, produced in the early twentieth century, have guided not only agricultural use but urban growth and development throughout much of the American West to this day. In Carpenter's time, most western states relied on the doctrine of prior appropriation--first in time, first in right--which granted exclusive use of resources to those who claimed them first, regardless of common needs. Carpenter feared that population growth and rapid agricultural development in states sharing the same river basins would rob Colorado of its right to a fair share of water. To avoid that eventuality, Carpenter invoked the compact clause of the U.S. Constitution, a clause previously used to settle boundary disputes, and applied it to interstate water rights. The result was a mechanism by which complex issues involving interstate water rights could be settled through negotiation without litigating them before the U.S. Supreme Court. Carpenter believed in the preservation of states' rights in order to preserve the constitutionally mandated balance between state and federal authority. Today, water remains critically important to the American West, and thegreat interstate water compacts Carpenter helped engineer constitute his most enduring legacy. Of particular significance is the Colorado River Compact of 1922, without which Hoover Dam could never have been built.
Part travelogue, part history, and part environmental treatise, "Mekong - The Occluding River" is above all else an urgent warning that factors such as pollution, ecological devastation, and the depletion of natural resources are threatening the very existence of the Mekong River. Author Ngo The Vinh combines his vivid travel notes and collection of photographs with a meticulously researched history of the environmental degradation of the Mekong River. Translated from Vietnamese, the best-selling treatise outlines the myriad threats facing the river today. From oil shipments feeding the industrial cities of southwestern China to gigantic hydroelectric dams known as the Mekong Cascades in Yunnan province, China is the worst environmental offender, though the other nations along Mekong's banks behave no better. From Thailand to Laos to Vietnam, hydroelectric dams that threaten the Mekong and its inhabitants are being built at an alarming rate. To save the Mekong, Ngo The Vinh calls upon all the nations that benefit from its life-giving water to observe the "Spirit of the Mekong" in the implementation of all future development projects. To achieve this end, there must be a concerted and sustained commitment to cooperation and sustainability. At this critical cross-roads, we should remind ourselves of the mantra from Sea World San Diego: "Extinction is forever. Endangered means we still have time."
Sharks are ruthlessly efficient predators, the apex of 450 million years of evolution. They are older than trees, have survived five extinction events and are essential to maintaining balanced ocean ecosystems, but how much do we really know about their lives? The first book to reveal the hidden world of sharks, Emperors of the Deep draws upon the latest scientific research to examine four species in detail – mako, tiger, hammerhead and great white – as never before. An eye-opening tour of shark habitats ranges from the coral reefs of the Central Pacific where great whites mysteriously congregate every autumn in what researchers call a festival for sharks, to tropical mangrove forests where baby lemon sharks play in social groups and to the frigid waters of the North Atlantic, home to 400-year-old Greenland sharks, the world’s longest-lived vertebrates. McKeever also traces the evolution of the myth of the ‘man-eater’ and exposes the devastating effects of the fishing industry on shark populations: In 2018 only four people died in shark attacks while we killed 100 million sharks. At once a journey through the misunderstood world of sharks and an urgent call to protect them, Emperors of the Deep celebrates these iconic predators that continue to capture our imagination – and that desperately need our help to survive.
Manatees are among nature's strangest-looking, gentlest animals. They're among America's most endangered mammals and were the basis for ancient tales of mermaids, legendary creatures that were half-fish and half-human.
A spectacular variety of life flourishes between the ebb and flow of high and low tide. Anemones talk to each other through chemical signaling, clingfish grip rocks and resist the surging tide, and bioluminescent dinoflagellates-single-celled algae-light up disturbances in the shallow water like glowing fingerprints. This guidebook helps readers uncover the hidden workings of the natural world of the shoreline. Richly illustrated and accessibly written, Between the Tides in Washington and Oregon illuminates the scientific forces that shape the diversity of life at each beach and tidepool-perfect for beachgoers who want to know why. Features include * profiles of popular and off-the-beaten-track sites to visit along the Greater Salish Sea, Puget Sound, and Washington and Oregon coasts * the fascinating stories behind both common and less familiar species * a lively introduction to how coastal ecosystems work and why no two beaches are ever alike
'What a fun book! Reading Sea Fever is enticing and intriguing, like watching floating treasure bob past your nose.' Tristram Gooley, author of The Natural Navigator Can you interpret the shipping forecast? Do you know your flotsam from your jetsam? Or who owns the foreshore?

Mixing advice on everything from seasickness to righting a capsized boat with arcane marine lore, recipes, history, dramatic stories of daring-do and guides to the wildlife we share our shores with, even the most experienced ocean-dweller will find something in these pages to surprise and delight.
Collected here in this omnibus edition are Henry David Thoreau's most important works including A Week on the Concord and Merrimack Rivers; The Selected Essays of Henry David Thoreau, including Civil Disobedience; and of course, Walden. A Week on the Concord and Merrimack Rivers is both a remembrance of an intensely spiritual moment in Henry David Thoreau's life and a memoriam to his older brother who accompanied him on the trip shortly before his death. Full of fascinating literary musings and philosophical speculations, this book is a true precursor to Walden. The Selected Essays contains nineteen essays (including Civil Disobedience). Thoreau was one of America's best known and most influential writers. His work has helped shape the American Discourse and had a lasting effect on the environmental movement in America. Walden is one of the best-known non-fiction books ever written by an American. It details Thoreau's sojourn in a cabin near Walden Pond, amidst woodland owned by his friend and mentor Ralph Waldo Emerson. Walden was written with expressed seasonal divisions. Thoreau hoped to isolate himself from society in order to gain a more objective understanding of it. Simplicity and self-reliance were Thoreau's other goals, and the whole project was inspired by Transcendentalist philosophy. This book is full of fascinating musings and reflections. As pertinent and relevant today as it was when it was first written.
For author M. Scotty Lamkin, a conventional lifestyle at a traditional job was a horribly mundane way to approach life. On January 16, 1979, he arrived in Alaska with fifty dollars in his pocket, two duffel bags, and a backpack. A long way from his Kentucky homeland, Lamkin journeyed to Alaska expecting adventure, and he was not disappointed. Chance Is the Providence of Adventurers narrates many of Lamkin's true-life escapades in Alaska's remote bush country. In this half-travelogue, half-memoir, Lamkin tells the sometimes funny, sometimes deadly, stories of his experiences as a professional guide and adventurer-waking up a brown bear at close range, sinking a boat in frigid Alaska waters, crashing bush planes, throwing rocks at bears, and experiencing some of the most beautiful landscapes on Earth. "Chance Is the Providence of Adventurers" offers a glimpse into the flavor of Alaskan life, provides a firsthand view of the wonders of untamed nature and wildlife, and demonstrates the results of taking a chance to change your life.
Much can be learned about the condition of the planet’s environment by looking at sea turtles. They have existed for over 100 million years, and they travel throughout the world’s oceans. Suddenly, however, they are struggling to survive - largely because of things people are doing to the planet’s oceans and beaches. But what does this mean for the human species? It is possible that a world in which sea turtles cannot survive may soon become a world in which humans struggle to survive. If, however, we learn from our mistakes and begin changing our behaviour, there is still time to save sea turtles from extinction. In the process, we will be saving one of the earth’s most mysterious and time-honoured creatures. We might just be saving ourselves too. South Africa has played an active role in this, protecting its own seaturtle populations and researching turtle populations in neighbouring countries. An early pioneer in conservation techniques, South Africa has assisted many countries and researchers, and the sea turtles of south-east Africa are now extensively protected, with positive signs of recovery. Between the Tides tells this remarkable story, as seen through the eyes of the author, whose interest in sea-turtle research has taken him all over the world and involved him in exciting expeditions, scientific controversy, political unrest, the companionship of wonderful people, both scientific and conservationist, and survival by sheer luck. His lasting reward has been his association with beautiful beaches and the wonderful family of sea turtles.
Fishermen, marine aquarists, biologists studying seashore and coastal waters, and those involved in trading shellfish and even restaurateurs are aware of the great diversity of crustaceans inhabiting the seas around the British Isles, Northern Europe and the Mediterranean. Crayfishes, Lobsters and Crabs of Europe will enable the reader to identify 42 crustacean species of commercial importance found in these regions during coastal explorations, fishing trips, displayed in public aquaria or available in restaurants, including selected freshwater crayfishes, deep-sea species and some imported species. The book also includes sections on the gross internal and external structure of these Crustacea, their life histories, classification and nomenclature. The book is of interest to students of marine biology and researchers in fisheries science.
The study of coelenterates is now one of the most active fields of invertebrate zoology. There are many reasons for this, and not everyone would agree on them, but certain facts stand out fairly clearly. One of them is that many of the people who study coelenterates do so simply because they are interested in the animals for their own sake. This, however, would be true for other invertebrate groups and cannot by itself explain the current boom in coelenterate work. The main reasons for all this activity seem to lie in the considerable concentration of research effort and funding into three broad, general areas of biology: marine ecology, cellular-developmental biology and neurobiology, in all of which coelenterates have a key role to play. They are the dominant organisms, or are involved in an important way, in a variety of marine habitats, of which coral reefs are only one, and this automatically ensures their claims on the attention of ecologists and marine scientists. Secondly, the convenience of hydra and some other hydroids as experimental animals has long made them a natural choice for a variety of studies on growth, nutrition, symbiosis, morphogenesis and sundry aspects of cell biology. Finally, the phylogenetic position of the coelenterates as the lowest metazoans having a nervous system makes them uniquely interesting to those neurobiologists and behaviorists who hope to gain insights into the functioning of higher nervous systems by working up from the lowest level.

This book describes the basic elements in the theory of animal breeding and inheritance of quantitative economic traits and the way in which this technology can be implemented in selective breeding programs for aquaculture species. The role and the implementation of molecular genetics in modern selective breeding programs is also addressed. The booka (TM)s main objective is to stimulate development of efficient selective breeding programs in aquaculture, the worlda (TM)s fastest growing industry for animal protein production. Considerable genetic gain from selection has been demonstrated for several aquatic species in traits like growth rate and survival. AKVAFORSK and allied institutions have demonstrated the value of selection in Atlantic salmon, rainbow trout, Nile tilapia, rohu carp and the shrimp Penaeus vannamei. Presently, however, less than 10 % of total world aquaculture production is based on genetically improved animals. The urgent challenge to the industry is to implement and start selective breeding programs in order to make the aquaculture industry more competitive and sustainable, through improving the utilization of feed, land and water resources. The text has been written by scientists at AKVAFORSK, Akvaforsk Genetics Center and co-workers in order to summarise present knowledge in the field, and to encourage implementation of selective breeding programs for economically important fish and shellfish species around the world.
