This updated and expanded guide thoroughly documents every aspect of seaweed life, from species identification and seaweed biology to the essential—and often surprising—roles seaweed plays in the marine ecosystem and our everyday lives. Seaweeds are used in everything from cosmetics to sustainable biofuels, and some species, like kelp, contribute to the remediation of coastal ecosystems. Featuring an attractive new full-color design, the expanded Pacific Seaweeds includes updated species descriptions, dozens of additional color photos, new species discovered since the original edition, and brand-new sections on common shore plants and the use of DNA techniques to discover, catalog and identify seaweeds. It also features several new recipes and an essay on umami—because in addition to all its other uses, some species of seaweed make delectable food. Packed with illustrations, vivid color photographs, comprehensive scientific information and further readings, this easy-to-use guidebook will appeal to marine biologists, amateur beachcombers, gourmet foragers and everyone in between.
What is rich with vitamins, minerals, carbohydrates and proteins, is used to develop everything from cosmetics to pesticides and can be found on any beach in the Pacific Northwest? The answer, many will be astonished to discover, is seaweed. An important food source in Asia for centuries, seaweed is increasingly used in the West for industrial and scientific chemicals, plant fertilizers and livestock feed supplements. Scientists are also just beginning to explore the medicinal value of seaweeds; the powerful nutrients in these amazing plants have been used to treat hypertension (high blood pressure), some cancers and strokes. With line drawings and vivid colour photographs, this easy-to-use book thoroughly documents every aspect of seaweed life, from species identification and seaweed biology to the essential - and often surprising - roles seaweed plays in the marine ecosystem and our everyday lives. Clear and informative, and packed with comprehensive scientific information, interesting facts, further readings and even an assortment of tasty seaweed recipes, this unique and highly readable guidebook will appeal to marine biologists, amateur beachcombers and everyone in between.
Students, scientists, mariculturists, beachcombers, boaters, kayakers, SCUBA divers, naturalists, subsistence users, shoreline managers, and anyone who walks along rocky shorelines between the Aleutian Islands, Alaska, and southern Oregon, USA, will welcome this new guide to 154 of the most abundant species of seaweeds and seagrasses to be found growing there.
Part I of this book presents the geographical distribution of seaweed and seagrasses around the world, environmental factors, floral history, and relavent paleo-oceanographic considerations. Part II covers seaweed ecophysiology, including relationships of light, temperature, salinity and other abiotic factors such as competition, herbivory, predation, and parasitism. Author's abstract.
This multivolume field guide covers the species of interest to fisheries of the major marine resource groups exploited in the Western Central Pacific. The area of coverage includes FAO Fishing Area 71 and the southwestern portion of Fishing Area 77 corresponding to the South Pacific Commission mandate area. The marine resource groups included are seaweeds, corals, bivalves, gastropods, cephalopods, stomatopods, shrimps, lobsters, crabs, holothurians, sharks, batoid fishes, chimaeras, bony fishes, estuarine crocodiles, sea turtles, sea snakes and marine mammals. The introductory chapter outlines the environmental, ecological and biogeographical factors influencing the marine biota as well as the basic components of the fisheries in the Western Central Pacific. Within the field guide, the sections on the resource groups are arranged phylogenetically according to higher taxonomic levels such as class, order and family. Each resource group is introduced by general remarks on the group, an illustrated section on technical terms and measurements and a key or guide to orders or families. Each family generally has an account summarizing family diagnostic characters, biological and fisheries information, notes on similar families occurring in the area, a key to species, a checklist of species and a short list of relevant literature. Families that are less important to fisheries include an abbreviated family account and no detailed species information. Species in the important families are treated in detail (arranged alphabetically by genus and species) and include the species name, frequent synonyms and names of similar species, an illustration, FAO common name(s), diagnostic characters, biology and fisheries information, notes on geographical distribution and a distribution map. For less important species, abbreviated accounts are used. Generally, this includes the species name, FAO common name(s), an illustration, a distribution map and notes on biology, fisheries and distribution. Each volume concludes with its own index of scientific and common names.
This all color field guide describes 136 species of seaweed that occur from Alaska to nothern Baja California. For each species there is one or more color photos. The narrative includes a brief description, goegraphical range and notes on natural history. Also included are sections on uses for seaweed, collecting and photographing seaweeds.
Seaweed is used in many countries for very different purposes - directly as food, especially in sushi, as a source of phycocolloids, extraction of compounds with antiviral, antibacterial or antitumor activity and as biofertilizers. About four million tons of seaweed are harvested annually worldwide. Of the various species known, less than 20 account for 90% of the biomass exploited commercially. This book details 147 species of edible seaweed, including scientific name and respective common names, geographic location, nutritional composition, uses and is extensively illustrated.
