An accessible introduction to large rivers, including coverage of the geomorphology, hydrology, ecology, and environments of large river systems This indispensible book takes a structured and global approach to the subject of large rivers, covering geomorphology, hydrology, ecology, and anthropogenic environment. It offers a thorough foundation for readers who are new to the field and presents enlightening discussions about issues of management at the worldwide scale. The book also examines possible future adaptations that may come about due to climate change. The book has benefitted from contributions by Professor W.J. Junk on the ecology of floodplains and Professor Olav Slaymaker on the large arctic rivers. Introducing Large Rivers is presented in three parts. Part 1 provides an introduction to the world's large rivers and their basins. It covers source, transfer, and storage of their water and sediment; Pleistocene inheritance; the ecology of channels and floodplains; deltas; and more. Several large rivers are discussed in the next part. These include the Amazon Mississippi, Nile, Ganga-Brahmaputra System, Mekong, and Yangtze. The last part examines changes in large rivers and our management of river systems. It studies anthropogenic alterations such as land use and deforestation in large river basins; structural control systems like dams and reservoirs on channels; and ecological changes. It finishes with chapters on the management of large rivers, covering both technical and political aspects, and the future of the world's big river systems. Introducing Large Rivers is ideal as an introductory textbook on large rivers for future earth and environmental scientists and river managers. It will also benefit advanced undergraduate and graduate students studying geography, geology, ecology, and river management.

Agile, sleek, and precise, sharks display many qualities we can admire and appreciate. These marvels of evolution have adapted to thrive in every major aquatic realm on the planet, from frigid Arctic waters through temperate but stormy seas and on into the tropics. However, few places on Earth are home to the amazing diversity of shark species that beautify the shallow waters of Florida and the Bahamas. In this first-ever book dedicated to the sharks of this region, biologist Jeffrey C. Carrier reveals the captivating lives of these large marine predators and describes how they have survived for over 400 million years. Guiding readers through basic biology, key attributes, and identification tips, the book explores what makes sharks such successful apex predators. Carrier explains fascinating phenomena, including the reason for the bizarre shape of the hammerhead, how a bull shark is able to swim hundreds of miles up freshwater rivers, what lies behind sharks' remarkable capability to learn and remember, and why many scientists believe that they are equipped with the most sophisticated sensory systems in the animal kingdom. With the stunning full-color underwater photography of Andy Murch, Jillian Morris, and Duncan Brake, Sharks of the Shallows brings boaters, fishers, divers, and shark lovers directly alongside these unfairly maligned creatures. And not a moment too soon! Sharks are experiencing stresses unlike any in their long history, and are struggling to survive in a changing ocean. They will continue to grace our coastlines only if we care enough to understand them.

Alaska pollock is everywhere. If you're eating fish but you don't know what kind it is, it's almost certainly pollock. Prized for its generic fish taste, pollock masquerades as crab meat in california rolls and seafood salads, and it feeds millions as fish sticks in school cafeterias and Filet-O-Fish sandwiches at McDonald's. That ubiquity has made pollock the most lucrative fish harvest in America-the fishery in the United States alone has an annual value of over one billion dollars. But even as the money rolls in, pollock is in trouble: in the last few years, the pollock population has declined by more than half, and some scientists are predicting the fishery's eventual collapse. In Billion-Dollar Fish, Kevin M. Bailey combines his years of firsthand pollock research with a remarkable talent for storytelling to offer the first natural history of Alaska pollock. Crucial to understanding the pollock fishery, he shows, is recognizing what aspects of its natural history make pollock so very desirable to fish, while at the same time making it resilient, yet highly vulnerable to overfishing. Bailey delves into the science, politics, and economics surrounding Alaska pollock in the Bering Sea, detailing the development of the fishery, the various political machinations that have led to its current management, and, perhaps most important, its impending demise. He approaches his subject from multiple angles, bringing in the perspectives of fishermen, politicians, environmentalists, and biologists, and drawing on revealing interviews with players who range from Greenpeace activists to fishing industry lawyers. Seamlessly weaving the biology and ecology of pollock with the history and politics of the fishery, as well as Bailey's own often raucous tales about life at sea, Billion-Dollar Fish is a book for every person interested in the troubled relationship between fish and humans, from the depths of the sea to the dinner plate.

From the bestselling author of Breath, a “fascinating, informative, exhilarating” voyage from the ocean’s surface to its darkest trenches (Wall Street Journal).

Fascinated by the sport of freediving—in which competitors descend great depths on a single breath—James Nestor embeds with a gang of oceangoing extreme athletes and renegade researchers. He finds whales that communicate with other whales hundreds of miles away, sharks that swim in unerringly straight lines through pitch-black waters, and other strange phenomena. Most illuminating of all, he learns that these abilities are reflected in our own remarkable, and often hidden, potential—including echolocation, directional sense, and the profound bodily changes humans undergo when underwater.

Along the way, Nestor unlocks his own freediving skills as he communes with the pioneers who are expanding our definition of what is possible in the natural world, and in ourselves.

From shark attack survivor to the shark's biggest advocate, Paul de Gelder tells us just why these majestic diverse animals need our help as much as we need them. Something happens to you the first time you dive with sharks... We have a perennial fascination with sharks. Portrayed in the media and popular culture as killing machines, we are awed by their power and strength. But the shark is so much more - a marvel of the sea, they have evolved over 450 million years into over 500 species, from the bioluminescent kitefin to the tiny dwarf lantern shark, the sociable lemon shark to the blue shark, which can birth up to 100 pups in one litter. Bringing balance to the ocean's ecosystem, our planet is at serious risk when these amazing creatures are threatened. Paul de Gelder, who lost two limbs in a shark attack during a mission as an elite Australian navy clearance diver, spent time as part of his recovery learning all about sharks. He became so obsessed that, despite what happened to him, he is now an expert and has dedicated his life to helping save them. Shark is his love-letter to these unfairly vilified animals, and his warning to the world about what will happen if we don't look out for them.

A captivating historical look at the cultural and artistic significance of shells in early modern Europe Among nature's most artful creations, shells have long inspired the curiosity and passion of artisans, artists, collectors, and thinkers. Conchophilia delves into the intimate relationship between shells and people, offering an unprecedented account of the early modern era, when the influx of exotic shells to Europe fueled their study and representation as never before. From elaborate nautilus cups and shell-encrusted grottoes to delicate miniatures, this richly illustrated book reveals how the love of shells intersected not only with the rise of natural history and global trade but also with philosophical inquiry, issues of race and gender, and the ascent of art-historical connoisseurship. Shells circulated at the nexus of commerce and intellectual pursuit, suggesting new ways of thinking about relationships between Europe and the rest of the world. The authors focus on northern Europe, where the interest and trade in shells had its greatest impact on the visual arts. They consider how shells were perceived as exotic objects, the role of shells in courtly collections, their place in still-life tableaus, and the connections between their forms and those of the human body. They examine how artists gilded, carved, etched, and inked shells to evoke the permeable boundary between art and nature. These interactions with shells shaped the ways that early modern individuals perceived their relation to the natural world, and their endeavors in art and the acquisition of knowledge. Spanning painting and print to architecture and the decorative arts, Conchophilia uncovers the fascinating ways that shells were circulated, depicted, collected, and valued during a time of remarkable global change.

Ponds and small lakes support an extremely rich biodiversity of fascinating organisms. Many people have tried pond-dipping and encountered a few unfamiliar creatures, such as dragonfly nymphs and caddisfly larvae. However, there is a far richer world of microscopic organisms, such as diatoms, desmids and rotifers, which is revealed in this book. Anyone with access to a microscope can open up this hidden dimension. Identification keys are provided so that readers can identify, explore and study this microscopic world. There are also many suggestions of ways in which readers can then make original contributions to our knowledge and understanding of pond ecology. The book not only explores the fascinating world of the creatures within ponds and their interactions, but also explains the many ways in which ponds are important in human affairs. Ponds are being lost around the world, but they are a key part of a system that maintains our climate. In the face of climate change, it has never been more important to understand the ecology of ponds. Includes keys to: A - Traditional key to kingdoms of organisms; B - Contemporary key to kingdoms of organisms; C - Pragmatic key to groups of microorganisms; D - Algae visible, at least en masse, to the naked eye; E - Periphyton, both attached to surfaces and free living; F - Protozoa; G- Freshwater invertebrates and; H - Common phytoplankton genera in ponds.

"A thorough and engaging history of Maine's rocky coast and its tough-minded people."-Boston Herald "[A] well-researched and well-written cultural and ecological history of stubborn perseverance."-USA Today For more than four hundred years the people of coastal Maine have clung to their rocky, wind-swept lands, resisting outsiders' attempts to control them while harvesting the astonishing bounty of the Gulf of Maine. Today's independent, self-sufficient lobstermen belong to the communities imbued with a European sense of ties between land and people, but threatened by the forces of homogenization spreading up the eastern seaboard.In the tradition of William Warner's Beautiful Swimmers, veteran journalist Colin Woodard (author of American Character: A History of the Epic Struggle Between Individual Liberty and the Common Good) traces the history of the rugged fishing communities that dot the coast of Maine and the prized crustacean that has long provided their livelihood. Through forgotten wars and rebellions, and with a deep tradition of resistance to interference by people "from away," Maine's lobstermen have defended an earlier vision of America while defying the "tragedy of the commons"-the notion that people always overexploit their shared property. Instead, these icons of American individualism represent a rare example of true communal values and collaboration through grit, courage, and hard-won wisdom.

The most comprehensive book about Florida's marine fishes ever produced, Marine Fishes of Florida includes hundreds of photographs and descriptions of species you'll encounter-plus many that are rare-when diving, snorkeling, kayaking, or fishing. Coverage includes both the Atlantic and Gulf coastline, from habitats near the shore to deeper waters. Fishes found in coastal rivers and other brackish waters are fully represented, as are offshore species that venture into Florida's waters often enough to be called "occasional visitors." David B. Snyder and George H. Burgess intertwine personal observations with results from research studies to provide accurate-often surprising-details. The result is a set of beautifully succinct identification descriptions coupled with information about each species' natural history. From the largest sharks to the smallest cryptic gobies, from homely toadfishes to the spectacularly colored reef fishes, this book is certain to help you better understand the fish you've seen or hooked. Features of Marine Fishes of Florida include * Color photographs by leading marine photographers* Differentiation of adult and juvenile forms* Coverage of 133 fish families and hundreds of species* Size and geographical range data* Natural history and conservation notes* Explanations of geologic history and current habitats

Humans everywhere have always been fascinated by octopuses, squid, and cuttlefish, known biologically as cephalopods. They evolved hundreds of millions of years ago and are related to molluscs such as mussels and snails. They can grow to an enormous size with eyes as big as footballs, but they still live for only a couple of years. They mate once in their lifetime and die shortly after. They have blue blood and three hearts and they can shoot out jet-black ink. They have a brain and have behaviours that could be interpreted as signs of intelligence, even though more than half of their brain is distributed in their arms. They are colour blind, but they can change the colour of their skin in a flash. They are masters of disguise and are able to alter the texture of their skin and the patterns displayed on it at lighting speed. They can also 'taste' using the suckers on their arms. They can move extremely fast thanks to a jet-propulsion system built into their body cavity. Although they are soft-bodied and look vulnerable, cephalopods are formidable predators. Octopuses have arms that are so strong that they can exert a force equal to hundreds of times their own body weight. Squid and cuttlefish can shoot out a tentacle to capture prey at the speed of a javelin thrown by an expert athlete. Cephalopods are, however, so much more than just fascinating creatures with strange physical characteristics. They are a nutritious, delicious protein source that has found a place for thousands of years in many food cultures around the world. As squid, cuttlefish, and octopuses are native to virtually all parts of the ocean, they are an excellent and available alternative to meat from terrestrial animals. This book is written to promote the overall place of cephalopods in home kitchens and to inspire the uninitiated to add them to their diet. It describes the many facets of their anatomy that play a central role in their potential use as healthy, diverse, and interesting food sources, with a particular emphasis on their taste and texture. By way of an assortment of recipes, the authors hope to dispel the myth that it is difficult to prepare delicious dishes using squid, cuttlefish, and octopuses. In addition, there are contributions to the on-going discussions about how marine resources can be exploited more responsibly in a sustainable manner. Ole G. Mouritsen is a professor of gastrophysics and culinary food innovation at the University of Copenhagen,president of the Danish Gastronomical Academy, and director of the Danish national research and communication centre Taste for Life. Klavs Styrbaek is a chef and leader of the gastronomic enterprise STYRBAEKS, which includes a gourmet restaurant, a cooking school, a catering service, and a product development branch.

An Underwater Guide to the Red Sea introduces over 1,000 species of invertebrate and over 200 species of coral, forming the basis of a marine eco-system which includes 1,100 species of fish, of which just under 20% are endemic. The high level of endemism is one of the main factors that makes scuba diving in Egypt so attractive. The dive sites offer unobstructed opportunities to spot tropical marine life in crystal-clear waters, ranging from sharks and dolphins to gorgonian fans and feather-stars. Diving types include shallow patch reefs, drift dives and walls, and a collection of some of the most interesting wrecks you are likely to find anywhere, including the world-famous Carnatic and Thistlegorm wrecks. Many of the reefs stretch out far into the sea and form intricate labyrinths of plateaus, lagoons, caves and gardens. Divided into three parts, the first is an introduction to diving and snorkelling in the Red Sea including what to expect and where to base yourself; next a guide to the best sites for diving and snorkelling; and finally a photographic identification of 282 of the most common species of fish, invertebrates, corals and megafauna. The second edition has been carefully updated, so that it continues to be an essential pocket guide for divers and snorkellers.
