Marine and freshwater systems are being placed under pressure like never before. A bigger and more demanding human population has meant increased utilisation of aquatic systems and, as such, the need for sustainable solutions to allow the development and conservation of these systems has become an international priority. In order to understand the limits of exploitation, an understanding is needed of the ecological principles that constrain levels of productivity and the systems' responses to exploitation pressure. This timely book explores current exploitation practices, and the ecological basis and consequences of that exploitation. From a consideration of the ecological effects of the extraction of non-living resources, including energy and water itself, it progresses to the biology and ecology of aquatic organisms, and how these underpin the harvesting for aquatic resources. A discussion of the ecological consequences for the system of its use as a means of transport and as a repository for wastes follows, along with the increasing importance of aquatic systems for human recreational pursuits. Finally, effective management strategies for natural hazards, the provision of ecological goods and services, and restoration of aquatic systems are considered, as well as the importance of ecological science in exploitation management. The role of science in providing an understanding of the effects of human intervention in aquatic systems is emphasised throughout, along with a consideration of the role of ecology in the sustainable management of the consequences of human activity.

Until recently, seaweed for most Americans was nothing but a nuisance, clinging to us as we swim in the ocean and stinking up the beach as it rots in the sun. With the ever-growing popularity of sushi restaurants across the country, however, seaweed is becoming a substantial part of our total food intake. And even as we dine with delight on maki, miso soup, and seaweed salads, very few of us have any idea of the nutritional value of seaweed. Here celebrated scientist Ole G. Mouritsen, drawing on his fascination with and enthusiasm for Japanese cuisine, champions seaweed as a staple food while explaining its biology, ecology, cultural history, and gastronomy. Mouritsen takes readers on a comprehensive tour of seaweed, describing what seaweeds actually are - algae, not plants - and how people of different cultures have utilized them since prehistoric times for a whole array of purposes - as food and fodder, for the production of salt, in medicine and cosmetics, as fertilizer, in construction, and for a number of industrial end uses, to name just a few. He reveals the vast abundance of minerals, trace elements, proteins, vitamins, dietary fiber, and precious polyunsaturated fatty acids found in seaweeds, and provides instructions and recipes on how to prepare a variety of dishes that incorporate raw and processed seaweeds. Approaching the subject from not only a gastronomic but also a scientific point of view, Mouritsen sets out to examine the past and present uses of this sustainable resource, keeping in mind how it could be exploited for the future. Because seaweeds can be cultivated in large quantities in the ocean in highly sustainable ways, they are ideal for battling hunger and obesity alike. With hundreds of delectable illustrations depicting the wealth of species, colors, and shapes of seaweed, "Seaweeds: Edible, Available, and Sustainable" makes a strong case for granting these "vegetables from the sea" a prominent place in our kitchens.

The deep-sea ecosystems include waters and sediments at the lowest layer in the ocean, existing below the thermocline and above the seabed, at a depth of 1000 fathoms (1800 m) or more. They represent the world's largest biome, covering more than 65% of the world surface and including more than 95% of the global biosphere. This book examines the marine biology, geology and human impact of the deep-sea environment. Topics discussed include the stratigraphical distribution and evolutionary classification of the schackoinid planktic foraminifera; the biological characteristics of the skilfish, erilepis zonifer in the North Pacific Ocean; protein degradation at deep-sea sediment; primary production and carbon cycling in the deep-sea; and biodiversity and ecosystem function in the deep-Mediterranean Sea.

This book is an informal introduction to marine biology using life on and near a floating dock in a ocean estuary as examples. We look at large and small animals and plants and follow the development of several species from egg to adult. Who eats who defines food chains in the Dock ecology. A major theme is that diversity and total mass increases as the size of organisms decrease: small is where the action is. Anyone can look under the Dock and see their own special community of organisms. Suggestions for microscopes, plankton nets, use of the Internet, and interacting with professional biologists are described at the end of the book.

Dr Alverson's story covers his early life experiences, through high school, World War II, his education and his involvement in State, Federal and International fisheries science and management. His career and story cover the period (1950-2000) during which world fisheries would explode from small boat coastal activities to distant water fleets of large vessels. World catches would increase over 300% after WWII and most of the worlds oceans and seas would be heavily exploited. Overfishing and impacts on coastal fisheries would lead the world community to seek new laws for the harvest of ocean fisheries and result in unilateral extension of national jurisdictions over ocean space. The growth of environmental movement in the later half of the 20th century would lead to conflicts between fishing and conservation groups resulting in changes in national and international fish policies. The book tracks many of these developments and DR Alverson's personal involvements and experiences during the traumatic period of world fishery expansion. During the course of his life marine fisheries resource would be seen as the great source of world protein to feed the worlds hungry and later as overfished and polluted.

Sub-Class?Cirripedia. Crustacea attached by the anterior end of the head, by cement proceeding from a modified portion of the ovaria; archetype composed of seventeen segments, with the three first of large size, and almost always developed into a carapace, not wholly exuviated, and capable of various movements; antenna none; eyes rudimentary; mouth prominent, formed by the partial confluence of the labrum, palpi, mandibles, and two pairs of maxilla; thorax attached to the internal sternal surface of the carapace, generally bearing six pairs of captorial, biramous, multi-articulated limbs; abdomen generally rudimentary; branchiae, lohen present, attached to the under sides of the carapace; generally bisexual, when unisexual, males epizoic on the female; penis single, generally probosciformed, seated at the posterior end of the abdomen; oviducts none; metamorphoses complex. Within the memory of many living naturalists, Cirripedes were universally looked on as belonging to the Molluscous kingdom; nor was this surprising, considering the fixed condition of their shells, and the degree of external resemblance between, on the one hand, Lepas and Teredo, and on the other hand, between Balanus and a Mollusc compounded of a patella and chiton. It is remarkable that this external false appearance overbore, even in the mind of Cuvier, his knowledge of their internal structure, namely, their lateral jaws, articulated appendages, and regular gan- glionic nervous system, which now strike us as such conclusive evidence of their position in the great Articulate kingdom. Straus was, I believe, the first who, in 1819, maintained that Cirripedes were most closely allied to Crustacea. But this view was disregarded, until J. Vaughan Thompson'sf capital discovery, in 1830, of...

The Lady and the Sharks...Filled with the Engaging Explorations and the Adventures of a Remarkable Woman, The Lady and the Sharks is about the joys of diving, exploring, and discovering the world that lives beneath the sea-about the pleasure and power of curiosity. This updated 4th edition recounts the birth and growth of a major marine science laboratory, and describes Genie Clark's fascinating tales about the behavior and physiology of sharks, fish and marine life. Genie's stories have inspired a continually growing audience of readers, scientists; students have inspired a continually growing audience of readers, scientists, students, collaborators, friends, children, and admirers. Eugenie Clark is an explorer, marine biologist, and teacher; she is a perfect example of the heights women can attain in scientific study. In 1955, she founded a small marine laboratory that grew to become the Mote Marine Laboratory in Sarasota, Florida, now a national center for shark and marine mammal research.
