"Numerous species of brown algae (Class Cyclosporeae: Order Fucales: Family Fucaceae) of the genus Sargassum occur throughout the world's tropical and temperate oceans. The pelagic complex in the western North Atlantic is comprised primarily of Sargassum natans and S. jluitans. Both species are hyponeustonic and fully adapted to a pelagic existence (Parr, 1939). Known commonly as gulf-weed, sea holly, or sargassum, they are characterized by a brushy, highly branched thallus (stem) with numerous leaf-like blades and berry-like pneumatocysts (floats). These floating plants may be up to several meters in length but are typically much smaller. See Hoyt (1918), Winge (1923), Parr (1939), Taylor (1960), Prescott (1968), and Humm (1979) for detailed descriptions of the various species"--Introduction, paragraph 1.
Latest Edition Explores Fresh, New Alternatives to Fossil FuelsThe Science of Renewable Energy, Second Edition takes a look at ways to produce sustainable and reliable energy sources and presents practical examples along with scientific methods, models, observations, and tools. Developed by esteemed author Frank R. Spellman, this book includes inpu
While artificial reefs may have much to offer, they remain an anecdote in the greater scheme of fisheries management, primarily due to the lack of data specific to validating their use. Based on papers presented at the 9th Conference on Artificial Reefs and Artificial Habitats (CARAH) and also including original articles written for this reference,
Renewable Energy Has a Good Side and a Bad Side Evaluate BothAll energy sources affect the environment in which we live. While fossil fuels may essentially do more harm, renewable energy sources can also pose a threat to the environment. Allowing for the various renewable energy sources: solar, wind, hydro, biomass, and geothermal, Environmental I
"The Southeast Fisheries Science Center (SEFSC) is one of five regional fishery research centers of the National Marine Fisheries Service (NMFS). In 1970, the NMFS was organized as a component of the National Oceanic and Atmospheric Administration (NOAA) in the U.S. Department of Commerce. The Fisheries Science Centers provide scientific information required for decisions relating to the conservation and management of fishery resources, and the protection of fishery habitats, endangered and threatened species. In 1972, the NOAA Technical Memorandum series was established and the Southeast Fisheries Science Center began the publication of research reports. The purpose of this series is timely dissemination of the results of scientific research. The series also affords the SEFSC a means of publishing research results in greater depth and detail than is normally allowed by scientific journals, which usually have stringent length restrictions. To address the difficulties of identification and location of these publications, we present the following listing of SEFSC Technical Memoranda from number 1 (1972) to number 340 (1993). They are available from their originating laboratories or from the National Technical Information Service. A directory of these sources is provided on page 2"--Introduction
The authoritative expert's guide to fascinating frogfishes and their unusual lives. Winner of the PROSE Award for Best Single Volume Reference in Science by the Association of American Publishers Unique among the world's fishes, frogfishes display a bizarre combination of attributes and behaviors that make them a subject of fervent study. Through cunning and trickery, they turn would-be predators into prey; they "walk" across the ocean floor and jet-propel through open water; some lay their eggs in a floating mucoid mass, while others employ complex patterns of parental care; and they are certainly among the most colorful of nature's productions. In Frogfishes, two of the world's leading anglerfish experts, Theodore W. Pietsch and Rachel J. Arnold, bring together an enormous amount of information about these incredible creatures. The only detailed exploration of frogfishes in print, the book touches on everything from their morphology and biomechanics to their diets and habitats. Enhanced with more than 500 spectacular color images, the book also includes • a thorough look at about 5,000 preserved specimens; • an annotated synonymy for all extant taxa, as well as keys and tables to facilitate identification; • insights into frogfish feeding, locomotion, mimicry, and reproductive behavior; • descriptions of recent scientific advances, including the discovery of new species, shifts in geographic distribution, and emerging DNA sequencing techniques; and • tips for frogfish-seeking divers and aquarists that emphasize conservation. Unmasking the mysteries of frogfish evolution and phylogenetic relationships through close examination of their fossil record, morphology, and molecular reconstruction, Frogfishes demonstrates the surprising diversity and beauty of this remarkable assemblage of marine shorefishes.
The first comprehensive review of the current and future effects of climate change on the world’s fisheries and aquaculture operations The first book of its kind, Climate Change Impacts on Fisheries and Aquaculture explores the impacts of climate change on global fisheries resources and on marine aquaculture. It also offers expert suggestions on possible adaptations to reduce those impacts. The world's climate is changing more rapidly than scientists had envisioned just a few years ago, and the potential impact of climate change on world food production is quite alarming. Nowhere is the sense of alarm more keenly felt than among those who study the warming of the world's oceans. Evidence of the dire effects of climate change on fisheries and fish farming has now mounted to such an extent that the need for a book such as this has become urgent. A landmark publication devoted exclusively to how climate change is affecting and is likely to affect commercially vital fisheries and aquaculture operations globally, Climate Change Impacts on Fisheries and Aquaculture provides scientists and fishery managers with a summary of and reference point for information on the subject which has been gathered thus far. Covers an array of critical topics and assesses reviews of climate change impacts on fisheries and aquaculture from many countries, including Japan, Mexico, South Africa, Australia, Chile, US, UK, New Zealand, Pacific Islands, India and others Features chapters on the effects of climate change on pelagic species, cod, lobsters, plankton, macroalgae, seagrasses and coral reefs Reviews the spread of diseases, economic and social impacts, marine aquaculture and adaptation in aquaculture under climate change Includes special reports on the Antarctic Ocean, the Caribbean Sea, the Arctic Ocean and the Mediterranean Sea Extensive references throughout the book make this volume both a comprehensive text for general study and a reference/guide to further research for fisheries scientists, fisheries managers, aquaculture personnel, climate change specialists, aquatic invertebrate and vertebrate biologists, physiologists, marine biologists, economists, environmentalist biologists and planners.
