Book Description
A swashbuckling narrative of treachery and obsession involving pirates, fur seals, competing governments, and near war. "In Roar of the Sea, [Deb Vanasse] writes with verve and dramatic impact, reconstructing the narrative of Elliott's tenacious crusade in a way that will transport the reader back to the cacophonous seal rookeries, to the bloody, blubber-slicked decks of the sealing ships, and to the elegant meeting rooms of the nation's capital. While bringing deserved attention to Elliott for his wildlife conservation work in the late 19th and early 20th centuries, Vanasse ends with a sobering challenge: those seal rookeries on the Pribilof Islands are now facing new human-caused threats—and could use 21st century advocates." —The Daily Astorian/Coast Weekend "Now comes a fascinating, full history of the fur seal story, pitting artist and advocate Henry Wood Elliott against the most famous of the seal pirates, a man named Alex MacLean, and a whole host of ill-informed and corrupt business and political titans. Deb Vanasse, a former Alaskan who now lives in Oregon and is the author of many previous books—including Wealth Woman, about the Klondike gold rush—has done extensive research to illuminate the historical characters, the difficulties of reaching an international agreement to protect wildlife, and the significance of that treaty today." —Anchorage Daily News Over a century ago, treachery in Alaska's Bering Sea twice brought the world to the brink of war. The US seized Canadian vessels, Great Britain positioned warships to strike the US, and Americans killed Japanese pirates on US soil—all because of the northern fur seals crowded together on the tiny Pribilof Islands. The herd's population plummeted from 4.7 million to 940,000 in the span of eight years while notorious seafarers like Alex MacLean (who inspired Jack London's The Sea-Wolf) poached indiscriminately. Enter an unlikely crusader to defend the seals: self-taught artist and naturalist Henry Wood Elliott, whose zeal and love for the animals inspired him to go against all odds and take on titans of the sea. Winning seemed impossible, and yet Elliott managed to expose corruption and set the course for modern wildlife protections that are all the more relevant today as the world grapples with mass extinction. Carefully written and researched, Roar of the Sea reveals the incredible hidden history of how one lone activist existing in the margins prevailed against national governments and corporate interests in the name of wildlife conservation.

Book Description
Two polar explorers are out to solve a mystery: Where is their special seal, Patches? Scientists Roxanne Beltran and Patrick Robinson set off on a polar adventure, traveling to Antarctica to study the lives of Weddell seals. By finding Patches, a wily seal they’ve been tracking since its birth, they’ll be able to learn a lot about how much the seals get to eat and how many pups they raise. A Seal Named Patches takes young readers into the world at the very bottom of the globe, where they meet the extraordinary animals that live in cold, icy conditions. Through breathtaking photos and real-life stories, young readers will learn about how scientists do fieldwork, the challenges of researching animals in harsh climates, and even what it’s like to fly a helicopter over Antarctica. This engaging story will especially entertain and educate children in grades K-2 (ages 5–8.)

Book Description
Pathology of Wildlife and Zoo Animals is a comprehensive resource that covers the pathology of wildlife and zoo species, including a wide scope of animals, disease types and geographic regions. It is the definitive book for students, biologists, scientists, physicians, veterinary clinicians and pathologists working with non-domestic species in a variety of settings. General chapters include information on performing necropsies, proper techniques to meet the specialized needs of forensic cases, laboratory diagnostics, and an introduction into basic principles of comparative clinical pathology. The taxon-based chapters provide information about disease in related groups of animals and include descriptions of gross and histologic lesions, pathogenesis and diagnostics. For each group of animals, notable, unique gross and microscopic anatomical features are provided to further assist the reader in deciding whether differences from the domestic animal paradigm are "normal." Additional online content, which includes text, images, and whole scanned glass slides of selected conditions, expands the published material resulting in a comprehensive approach to the topic. - 2019 PROSE Awards - Winner: Category: Textbook/Biological and Life Sciences: Association of American Publishers - Presents a single resource for performing necropsies on a variety of taxa, including terrestrial and aquatic vertebrates and invertebrates - Describes notable, unique gross and microscopic anatomical variations among species/taxa to assist in understanding normal features, in particular those that can be mistaken as being abnormal - Provides consistent organization of chapters with descriptions of unique anatomic features, common non-infectious and infectious diseases following brief overviews of the taxonomic group - Contains full-color, high quality illustrations of diseases - Links to a large online library of scanned slides related to topics in the book that illustrate important histologic findings
