    Over time, seahorses have surfaced in some unlikely places. We see them immortalized in the decorative arts; in tribal folklore, literature, and ancient myth; and even on the pages of the earliest medical texts, prescribed to treat everything from skin complaints to baldness to flagging libido. Marine biologist Helen Scales eloquently shows that seahorses are indeed fish, though scientists have long puzzled over their exotic anatomy, and their very strange sex lives?male seahorses are the only males in the animal world that experience childbirth! Our first seahorse imaginings appeared six thousand years ago on cave walls in Australia. The ancient Greeks called the seahorse hippocampus (half-horse, half-fish) and sent it galloping through the oceans of mythology, pulling the sea god Poseidon?s golden chariot. The seahorse has even been the center of a modern-day international art scandal: A two-thousand-year-old winged seahorse brooch was plundered by Turkish tomb raiders and sold to the Metropolitan Museum of Art in New York. A book that is as charming as the seahorse itself, Poseidon?s Steed brings to life an aquatic treasure.Seahorses lead quiet lives, tucked away out of sight on the seafloor. It is rare to catch a glimpse of a seahorse in its natural habitat. But even if few have seen one live, these exotic, seemingly prehistoric creatures exist quite vividly in our imaginations and they have mesmerized scientists, artists, and storytellers throughout time with their otherworldly rarity. Poseidon?s Steed is a sweeping journey that takes us from the coral reefs and seagrass meadows of Indonesia where many seahorses makes their natural habitat to the back streets of Hong Kong where a thriving black market seahorse trade is concealed. Throughout history, seahorses have surfaced in some unexpected places and Scales also follows the seahorse back in time, from our most rudimentary seahorse imaginings six thousand years ago on cave walls in Australia, to the myths of ancient Greece. Scientists have long puzzled over seahorses? unusual anatomy and their very strange sex lives. And male seahorses are the only males in the animal world that experience childbirth! Seahorses are not what scientists call a ?keystone? species. They rely on a healthy ocean to survive, but the marine ecosystem does not rely on them. But their delicate beauty reminds us that we rely on the seas not only to fill our dinner plates, but also to feed our imaginations.

    This book is, like its author, a unique achievement. Weaving a vivid portrait of her own life and her bees' lives through the seasons, Hubbell writes "about bees to be sure, but also about other things: the important difference between loneliness and solitude . . . the accommodating of oneself to nature" (Philadelphia Inquirer).

    Hoyt's elegant writing provides both the historical background for deep-sea exploration and an ecological perspective on life in the ocean's depths." -- American Scientist"A magnificent bestiary ... and a reminder of how little we actually know about the seas surrounding us." -- Popular ScienceWinner, Outstanding Nonfiction Book of the Year -- American Society of Journalists and Authors, Inc., New YorkIn this updated and expanded edition of Creatures of the Deep, award-winning nature and science writer Erich Hoyt gives readers a glimpse of the amazing variety of creatures found in the deepest parts of the ocean. Weaving together details from the latest scientific research about sharks, giant squid, dragonfish, huge tube worms, clams and tiny microbes of the deep-sea vents, Hoyt embarks on a magical journey roaming across the abyssal plains and descending into deep-sea trenches more than 20,000 feet down.Hoyt unravels the complex predator-prey relationships, from "killer" copepods to battles between giant squid and sperm whales, presenting compelling portraits of animals that are superbly adapted denizens of a dark high-pressure world. There are life forms, independent of sunlight and photosynthesis, which flourish around the hot, sulfurous deep-sea vents in the magnificent rift valley of the mid-ocean ridge, the world's longest mountain range. Surviving in conditions that appear to be close to the very soup of primordial Earth, these microbes have become the basis for the latest research into Earth's origins. Fully illustrated with fantastic underwater imagery.

    They evolved from land-roaming, dog-like creatures into animals that move like fish, breathe like us, can grow to 300,000 pounds, live 200 years and roam entire ocean basins. Whales fill us with terror, awe, and affection--yet we know hardly anything about them, and they only enter our awareness when they die, struck by a ship or stranded in the surf. Why did it take whales over 50 million years to evolve to such big sizes, and how do they eat enough to stay that big? How did their ancestors return from land to the sea? Why do they beach themselves? What do their lives tell us about our oceans, and evolution as a whole? Importantly, in the sweepstakes of human-driven habitat and climate change, will whales survive?Nick Pyenson's research has given us the answers to some of our biggest questions about whales. Nick's rich storytelling takes us to the cool halls deep inside the Smithsonian's priceless fossil collection, to the frigid fishing decks on Antarctic whaling stations, and to the blazing hot desert of Chile where scientists race against time to document the largest fossil whalebone site on earth. Spying on Whales is science writing at its best: an author who is an incredible, passionate writer, at the forefront of his field, on a topic that invokes deep fascination.

    Explore the incredible diversity of life in the sea--from the haunting, hour-long songs of humpback whales to the fantastic coral colonies that spawn all their young in a single night.

    He visits Norwegian megafarms that use genetic techniques once pioneered on sheep to grow millions of pounds of salmon a year. He travels to the ancestral river of the Yupik Eskimos to see the only Fair Trade–certified fishing company in the world. He makes clear how PCBs and mercury find their way into seafood; discovers how Mediterranean sea bass went global; challenges the author of Cod to taste the difference between a farmed and a wild cod; and almost sinks to the bottom of the South Pacific while searching for an alternative to endangered bluefin tuna.Fish, Greenberg reveals, are the last truly wild food — for now. By examining the forces that get fish to our dinner tables, he shows how we can start to heal the oceans and fight for a world where healthy and sustainable seafood is the rule rather than the exception.

    Shows and describes more than eight hundred species, and provides information on distribution, characteristics, and behavior.

    Well, I was diagnosed 24 years ago, and I still learned something new on every page.”—Michael Kinsley, Vanity Fair columnist and author of Old Age: A Beginner’s Guide Here is the book that John Vine and his wife, Joanne, wish they could have consulted when John was first diagnosed with Parkinson’s disease—a nontechnical, personal guide written from the patient’s perspective. Relying on his experiences over the past 12 years, John writes knowledgeably about all aspects of the disease. John also interviewed other Parkinson’s patients and their partners, whose stories and advice he includes throughout the book. “I wish we’d had John Vine’s book when my brother-in-law was diagnosed. The book is highly informative, unflinchingly honest, and reassuringly optimistic. It’s just what the doctor should have ordered.”—Cokie Roberts, best-selling author and political commentator on ABC News and NPR “John Vine details, in a compelling and accessible way, his experience with Parkinson’s disease. His book is an extraordinary guide to living successfully with Parkinson’s, and a must read for all who want to better understand the condition. Although diagnosed with Parkinson’s, my father lived an active and productive life until his death at age 94. As the book makes clear, while each patient’s journey is unique, common approaches are indispensable in treating the symptoms of the disease.”—Eric H. Holder, Jr. served as the 82nd Attorney General of the United States from 2009 to 2015 “John Vine has written the best primer I’ve ever read for newly diagnosed Parkinson’s patients and their families. It helps them cope with the shock of diagnosis, gives them (jargon-free) the scientific basics they need to know, describes the symptoms they may experience (making clear that every case is different) and catalogs the resources available to navigate living with Parkinson’s. John humanizes the book by describing his own experience and that of 22 other patients and their partners. I’d urge every neurologist to have copies of Vine’s primer on hand to help new PD on their journey forward.”—Morton Kondracke, author of Saving Milly: Love, Politics and Parkinson’s Disease and a member of the Founders' Council of the Michael J. Fox Foundation “My husband has PD, and I devoured this book. It’s wise, wonderfully readable, and, above all, helpful. Since John Vine has PD, he speaks with great authority about the challenges, both physical and psychological. If you have Parkinson’s, live with someone who has it, or just know someone battling the disease, A Parkinson’s Primer is for you.”—Lesley Stahl, award-winning television journalist on the CBS News program 60 Minutes “This is a remarkable book describing the personal experiences of many individuals, including the author, living with Parkinson’s disease. It captures the fact that although there are many possible symptoms in this disease, each person experiences different symptoms and copes with them in various ways. The thoughtful and insightful comments and coping strategies should be helpful for persons with PD, and their partners, regardless of the stage of the disease.”—Stephen Grill, MD, PhD, Director of the Parkinson’s & Movement Disorders Center of Maryland John M. Vine is a lawyer at Covington & Burling LLP in Washington, DC, where he is the senior member and former head of the firm’s employee benefits group. He was diagnosed with Parkinson’s in 2004.

    Her reward for the grueling work of rescuing birds—such as feeding baby hummingbirds every twenty minutes all day long—is her empathy with them and the satisfaction of knowing the world is a birdier and more beautiful place. The Bluebird Effect is about the change that's set in motion by one single act, such as saving an injured bluebird—or a hummingbird, swift, or phoebe. Each of the twenty five chapters covers a different species, and many depict an individual bird, each with its own personality, habits, and quirks. And each chapter is illustrated with Zickefoose's stunning watercolor paintings and drawings. Not just individual tales about the trials and triumphs of raising birds, The Bluebird Effect mixes humor, natural history, and memoir to give readers an intimate story of a life lived among wild birds.
