There are nearly 1,000 species of freshwater fishes in North America alone, and identifying them can sometimes be a daunting task. In fact, in just the twenty years since publication of the first edition of the "Peterson Field Guide to Freshwater Fishes," the number of species has risen by almost 150, including 19 marine invaders and 16 newly established nonnative species. This second edition incorporates all of these new species, plus all-new maps and a collection of new and revised plates. Some of the species can be told apart only by minute differences in coloration or shape, and these beautifully illustrated plates reveal exactly how to distinguish each species.
The guide includes detailed maps and information showing where to locate each species of fish--whether that species can be found in miles-long stretches of river or small pools that cover only dozens of square feet. The ichthyologic world of the twenty-first century is not the same as it was in the twentieth, and this brand-new edition of the definitive field guide to freshwater fishes reflects these many changes.

When it comes to fly fishing, simpler is better. Modern-day fly fishing, like much in life, has become exceedingly complex, with high-tech gear, a confusing array of flies and terminal tackle, accompanied by high-priced fishing guides. This book reveals that the best way to catch trout is simply, with a rod and a fly and not much else. The wisdom in this book comes from a simpler time, when the premise was: the more you know, the less you need. It teaches the reader how to discover where the fish are, at what depth, and what they are feeding on. Then it describes the techniques needed to present a fly at that depth, make it look lifelike, and hook the fish. With chapters on wet flies, nymphs, and dry flies, its authors employ both the tenkara rod as well as regular fly fishing gear to cover all the bases. Illustrated by renowned fish artist James Prosek, with inspiring photographs and stories throughout, Simple Fly Fishing reveals the secrets and the soul of this captivating sport.

Seashells have been the most coveted and collected of nature's creations for thousands of years. They were money before coins, jewellery before gems, art before canvas. In The Sound of the Sea, Cynthia Barnett blends cultural history and environmental science to trace our long love affair with seashells and the hidden lives of the mollusks that make them. From the mysterious glow of giant clams to the surprising origin of Shell Oil as a family business importing exotic shells, the book is filled with unforgettable stories. As it explores the perfect symmetry of a Chambered Nautilus, the pink-glossed lip of a Queen Conch or what we hear when we hold a shell to the ear, it makes a powerful argument for listening to shells-and acting on what they are telling us about the impacts of climate change on the seas, marine life and humanity.

Our oceans are in an ecological crisis due to their contamination with millions of tons of toxic microplastic particles. In just a few years, the volume of microplastic particles will exceed that of plankton in our oceans and turn them into a huge sea of plastic. This publication brings together numerous international art projects related to environmental activities, DIY biotechnology, and science, and draws attention to the irreversible destruction of our marine ecosystems - the current threat posed by the loss of marine animal biodiversity, for example, or the decline in oxygen production due to massive plankton loss. It also presents current scientific findings on sustainable alternatives to plastic.

Although Herman Melville's Moby-Dick is beloved as one of the most profound and enduring works of American fiction, we rarely consider it a work of nature writing--or even a novel of the sea. Yet Pulitzer Prize-winning author Annie Dillard avers Moby-Dick is the "best book ever written about nature," and nearly the entirety of the story is set on the waves, with scarcely a whiff of land. In fact, Ishmael's sea yarn is in conversation with the nature writing of Emerson and Thoreau, and Melville himself did far more than live for a year in a cabin beside a pond. He set sail: to the far remote Pacific Ocean, spending more than three years at sea before writing his masterpiece in 1851. A revelation for Moby-Dick devotees and neophytes alike, Ahab's Rolling Sea is a chronological journey through the natural history of Melville's novel. From white whales to whale intelligence, giant squids, barnacles, albatross, and sharks, Richard J. King examines what Melville knew from his own experiences and the sources available to a reader in the mid-1800s, exploring how and why Melville might have twisted what was known to serve his fiction. King then climbs to the crow's nest, setting Melville in the context of the American perception of the ocean in 1851--at the very start of the Industrial Revolution and just before the publication of On the Origin of Species. King compares Ahab's and Ishmael's worldviews to how we see the ocean today: an expanse still immortal and sublime, but also in crisis. And although the concept of stewardship of the sea would have been entirely foreign, if not absurd, to Melville, King argues that Melville's narrator Ishmael reveals his own tendencies toward what we would now call environmentalism. Featuring a coffer of illustrations and an array of interviews with contemporary scientists, fishers, and whale watch operators, Ahab's Rolling Sea offers new insight not only into a cherished masterwork and its author but also into our evolving relationship with the briny deep--from whale hunters to climate refugees.

Located between the Pacific and Indian Oceans, and between the Asian and Australian continents, the seas of the Indonesian Archipelago have a significant role in global weather patterns and oceanic circulation. The dynamic interplay between geological, physical, chemical, and biological processes, past and present, has given rise to one of the most diverse marine regions on the planet. The exceptional marine and coastal ecosystem diversity of the Indonesian archipelago provides hundreds of habitats that support thousands of species. This treasure trove of marine biodiversity has sustained the people of the archipelago for thousands of years. Population growth and socio-economic development place many of these resources at increasing risk of overexploitation. Using maps and numerous illustrations, The Ecology of the Indonesian Seas describes the complex and ecologically vulnerable coastal and marine ecosystems of the region in rich detail. Discussion of development, resource use and ecologically sustainable management plans is also incorporated. The first step towards sustainable use of marine and coastal resources, this book will be a valuable tool for ecologists, marine biologists, resource managers, government planners, and all those with an interest in the ecology of the region. Bound in two parts, of which this is the first, this book is part of The Ecology of Indonesia series.
