This book was released on 1975 with total page 730 pages. Available in PDF, EPUB and Kindle. Book excerpt: A total of 27 species and 13 formae from 13 genera were identified and enumerated. One genus and 8 species are new records for the Caribbean including one rare species, Desmopterus gardineri. Temperature-salinity-plankton diagrams were constructed for each species and used to determine water mass preferences and environmental ranges. Horizontal contours were used to delineate areas of high and low thecosome production. The highest productions were located in the south central sections of the Caribbean and were associated with areas of upwelling. The poorest areas for production occurred in waters with low nutrient levels in the central Caribbean running from the southeast to the northwest. Most of the species exhibited diurnal vertical migrations, with the adults showing the strongest migrations. The juveniles of most species displayed weaker migratory patterns than their adult counterparts and generally occupied higher or the same levels in the water column.

This book was released on 2008-12-28 with total page 545 pages. Available in PDF, EPUB and Kindle. Book excerpt: Life began in the sea, and even today most of the deep diversity of the planet is marine. This is often forgotten, especially in tropical countries like Costa Rica, renowned for their rain forests and the multitude of life forms found therein. Thus this book focusing on marine diversity of Costa Rica is particularly welcome. How many marine species are there in Costa Rica? The authors report a total of 6,777 species, or 3. 5% of the world’s total. Yet the vast majority of marine species have yet to be formally described. Recent estimates of the numbers of species on coral reefs range from 1–9 million, so that the true number of marine species in Costa Rica is certainly far higher. In some groups the numbers are likely to be vastly higher because to date they have been so little studied. Only one species of nematode is reported, despite the fact that it has been said that nematodes are the most diverse of all marine groups. In better studied groups such as mollusks and crustaceans, reported numbers are in the thousands, but even in these groups many species remain to be described. Indeed the task of describing marine species is daunting – if there really are about 9 million marine species and Costa Rica has 3. 5% of them, then the total number would be over 300,000. Clearly, so much remains to be done that new approaches are needed. Genetic methods have en- mous promise in this regard.

Book excerpt: This richly illustrated book presents the diversity and natural history of sea snail groups. By integrating aspects of morphology, ecology, evolution and behaviour, it describes how each group copes with problems of defence, locomotion, nutrition, reproduction and embryonic development. First come general characteristics of the Mollusca, to which snails belong; and next, characteristics by which snails (Gastropoda) differ from other molluscs. Then a broad, panoramic view of all major sea snail groups, from the primitive to the more advanced, is presented, including both the more abundant and some remote ones of special interest. In detailing primitive sea snails, first limpets (Patellogastropoda) are described, followed by brush snails (Vetigastropoda: top-shells, turbans and allies) and nerites (Neritimorpha), a small group with remarkably high variation in shell colour and in habitats. In looking at advanced-snails (Caenogastropoda), it details the herbivorous grazers and filter-feeders and the many voracious predators, some which use venomous darts. The book also covers sea slugs (Opisthobranchia), which have shifted from mechanical to chemical defence; some are herbivores, some use their food to harness solar energy, others are predators that gain stinging cells and poisonous compounds from their food. In addition, readers will learn about aspects of sea snails in human culture, including use as sacred artefacts and objects of magic and money, as a source of the royal and sacred dyes of purple and blue and as holy ceremonial trumpets. The text, in which scientific terms are accompanied by parallel common ones, is accompanied by over 200 illustrations (mostly in colour). This comprehensive, insightful portrait of sea snails will appeal to marine biologists, zoology lecturers and students, biology teachers, field-school instructors, nature reserve wardens, amateur naturalists, as well as to lecturers and learners of human culture.

This book was released on 2010-07-16 with total page 550 pages. Available in PDF, EPUB and Kindle. Book excerpt: Primary sexual traits, those structures and processes directly involved in reproduction, are some of the most diverse, specialized, and bizarre in the animal kingdom. Moreover, reproductive traits are often species-specific, suggesting that they evolved very rapidly. This diversity, long the province of taxonomists, has recently attracted broader interest from evolutionary biologists, especially those interested in sexual selection and the evolution of reproductive strategies. Primary sexual characters were long assumed to be the product of natural selection, exclusively. A recent alternative suggests that sexual selection explains much of the diversity of "primary" sexual characters. A third approach to the evolution of reproductive interactions after copulation or insemination has been to consider the process one of sexual conflict. That is, the reproductive processes of a species may reflect, as does the mating system, evolution acting on males and on females, but in different directions. In this volume, authors explore a wide variety of primary sexual characters and selective pressures that have shaped them, from natural selection for offspring survival to species-isolating mechanisms, sperm competition, cryptic female choice and sexual arms races. Exploring diverse reproductive adaptations from a theoretical and practical perspective, The Evolution of Primary Sexual Characters will provide an unparalleled overview of sexual diversity in many taxa and an introduction to the issues in sexual selection that are changing our view of sexual processes.

Available in PDF, EPUB and Kindle. Book excerpt: What do we know about Mediterranean Cold (Deep)-Water coral ecosystems? In this book, specialists offer answers and insights with a series of chapters and short papers about the paleoecology, biology, physiology and ecology of the corals and other organisms that comprise these ecosystems. Structured on a temporal axis—Past, Present and Future—the reviews and selected study cases cover the cold and deep coral habitats known to date in the Mediterranean Basin. This book illustrates and explains the deep Mediterranean coral habitats that might have originated similar thriving ecosystems in today’s Atlantic Ocean.

Available in PDF, EPUB and Kindle. Book excerpt: Jellyfish are one of the most conspicuous animals in our oceans and are renowned for their propensity to form spectacular blooms. The unique features of the biology and ecology of jellyfish that enable them to bloom also make them successful invasive species and, in a few places around the world, jellyfish have become problematic. As man increasingly populates the world’s coastlines, interactions between humans and jellyfish are rising, often to the detriment of coastal-based industries such as tourism, fishing and power generation. However we must not lose sight of the fact that jellyfish have been forming blooms in the oceans for at least 500 million years, and are an essential component of normal, healthy ocean ecosystems. Here many of the world’s leading jellyfish experts explore the science behind jellyfish blooms. We examine the unique features of jellyfish biology and ecology that cause populations to ‘bloom and bust’, and, using case studies, we show why jellyfish are important to coastal and ocean ecosystem function. We outline strategies coastal managers can use to mitigate the effects of blooms on coastal industries thereby enabling humans to coexist with these fascinating creatures. Finally we highlight how jellyfish benefit society; providing us with food and one of the most biomedically-important compounds discovered in the 20th century.

Available in PDF, EPUB and Kindle. Book excerpt: "Ponder and Lindberg provides a breathtaking overview of the evolutionary history of the Mollusca, effectively melding information from anatomy, ecology, genomics, and paleobiology to explore the depths of molluscan phylogeny. Its outstanding success is due to thoughtful planning, focused complementary contributions from 36 expert authors, and careful editing. This volume is a must for malacologists."—Bruce Runnegar, Department of Earth and Space Sciences, University of California, Los Angeles "Our understanding of the phylogeny and evolutionary history of the mollusca has been revolutionized over the past two decades through new molecular data and analysis, and reinvestigation of morphological characters. In this volume Ponder, Lindberg, and their colleagues do a wonderful job of integrating this work to provide new perspectives on the relationships of the major molluscan clades, their evolutionary dynamics, and their history. Particularly timely is the coverage of molluscan evo-devo and genomics."—Douglas H. Erwin, Curator of Paleozoic Invertebrates, National Museum of Natural History
