Marine algae are the supreme eco-engineers of life: they oxygenate the waters, create habitat for countless other organisms, and form the base of a food chain that keeps our planet unique in the universe as we know it. In this beautiful volume Josie Iselin explores both the artistic and the biological presence of sixteen seaweeds and kelps that live in the thin region where the Pacific Ocean converges with the North American continent-a place of incomparable richness. Each species receives a detailed description of its structure, ecological importance, and humans' scientific inquiry into it, told in scientifically illuminating yet deeply reverent and inspired prose. Throughout the writings are historical botanical illustrations and Iselin's signature, Marimekko-like portraits of each specimen that reveal their vibrant colors-whether rosy, "olivaceous," or grass-green-and whimsical shapes. Iselin posits that we can learn not only about the seaweeds but also from them: their resilience, their resourcefulness, their poetry and magic.

This is the first comprehensive reference on New Zealand freshwater fishes since the publication of Bob McDowell's field guide (Heinemann Reed) over 12 years ago. It includes all freshwater fishes, both introduced and native fishes, with useful identification charts at the back of the book for bullies and whitebait (diadromous galaxids). Rod Morris has gone to great lengths to capture the very best images and numerous colour photographs through the book will assist in identifying the male and female of the species, and the subtle differences between related fishes. An extensive introduction includes highly topical coverage of freshwater ecology and conservation issues surrounding the quality of New Zealand's waterways, making this book an invaluable information resource. In addition, keen anglers will be delighted to find full entries on trout, salmon, and rudd, including rare hybrids. And mini-maps provided for each entry give an indication of the distribution of each species throughout the country.

The image most of us have of whalers includes harpoons and intentional trauma. Yet eating commercially caught seafood leads to whales' entanglement and slow death in rope and nets, and the global shipping routes that bring us readily available goods often lead to death by collision. We-all of us-are whalers, marine scientist and veterinarian Michael J. Moore contends. But we do not have to be. Drawing on over forty years of fieldwork with humpback, pilot, fin, and in particular, North Atlantic right whales-a species whose population has declined more than twenty percent since 2017-Moore takes us with him as he performs whale necropsies on animals stranded on beaches, in his independent research alongside whalers using explosive harpoons, and as he tracks injured whales to deliver sedatives. The whales' plight is a complex, confounding, and disturbing one. We learn of existing but poorly enforced conservation laws and of perennial (and often failed) efforts to balance the push for fisheries profit versus the protection of endangered species caught by accident. But despite these challenges, Moore's tale is an optimistic one. He shows us how technologies for rope-less fishing and the acoustic tracking of whale migrations make a dramatic difference. And he looks ahead with hope as our growing understanding of these extraordinary creatures fuels an ever-stronger drive for change.

Yellowstone, the world's first national park and one of America's truly great trout fisheries, has been a crucible for ideas on how to look after wild places. Renowned Australian fishing writer Greg French gives a sparkling firsthand account of how the park's history, landscapes, wildlife, and people have touched anglers worldwide -- and why this matters. The Imperiled Cutthroat is a travelogue that covers the story of the Yellowstone cutthroat trout: its discovery, biology, decimation, modern-day allure, and uncertain future. Although set against the dramatic backdrop of Yellowstone, comparisons to Australia, New Zealand, and Europe are inevitable. It is a cautionary tale too, ending up in Mongolia, which is as pristine as Montana once was. The Yellowstone fishery is at a crossroads, and debate about what to do is dangerously narrow. Anglers everywhere need to be constantly reminded that hatcheries are far from a panacea for ailing fisheries: fostering conservation of the natural environmental delivers far better outcomes at a fraction of the cost. The power of Greg's stories comes not just from the quality of the writing but also from the quirks and passions of the people he meets. Greg's compelling storytelling enthralls anglers and naturalists the world over.

A breathtaking collection of photographs and expert commentary that shed light on the most mysterious creatures of the deep seaJellyfish come in a dazzling array of colors, shapes, and sizes, drifting through every ocean, from the surface to the deepest of the deep seas, and are even found in freshwater locations. These ancient creatures, also called sea jellies (they are not, technically, fish), are so otherworldly and luminous that it is no wonder they are often compared to mythical shapeshifters. Some are so delicate that they shatter with the smallest disturbance to the water, while the tenacity of others means they can withstand almost any temperature, any salinity, starvation, and even being dismembered. And some are truly biologically immortal. This visually breathtaking book showcases 100 species of jellyfish within its pages—from the ubiquitous Aurelia to the enigmatic Velella—along with astounding facts about these fascinating marine life-forms. Some are splendid, some strange, some poisonous, some deadly. Some carry surprising secrets and some are barely known, but every one of them is remarkable and has a tale to tell. An introduction by noted expert Lisa-ann Gershwin, with her commentary throughout, invites you into the wondrous world of jellyfish.

Jellyfish, with their undulating umbrella-shaped bells and sprawling tentacles, are as fascinating and beautiful as they are frightening and dangerous. They are found in every ocean at every depth, and they are the oldest multi-organed life form on the planet, having inhabited the ocean for more than five hundred million years. In many places they are also vastly increasing in number, and these population blooms may be an ominous indicator of the rising temperatures and toxicity of the world's oceans. Jellyfish presents these aquarium favorites in all their extraordinary and captivating beauty. Fifty unique species, from stalked jellyfish to black sea nettles, are presented in stunning color photographs along with the most current scientific information on their anatomy, history, distribution, position in the water, and environmental status. Foremost jellyfish expert Lisa-ann Gershwin provides an insightful look at the natural history and biology of each of these spellbinding creatures, while offering a timely take on their place in the rapidly changing and deteriorating condition of the oceans. Readers will learn about immortal jellyfish who live and die and live again as well as those who camouflage themselves amid sea grasses and shells, hiding in plain sight. Approachably written and based in the latest science and ecology, this colorful book provides an authoritative guide to these ethereal marine wonders.
