Book Description
Echinoderms are an ancient and diverse group of marine animals with a rich fossil record. They occur abundantly in all modern oceans and at all depths, where they contribute importantly to patterns in biodiversity and to the structure and functioning of marine systems. It is therefore vital to understand how they will respond to a rapidly changing ocean climate and other anthropogenic stressors, informed by both the dynamics of the fossil record and responses of extant species. The theme of the 13th International Echinoderm Conference (Hobart, Tasmania, 5-9 January 2009) was the response of echinoderms to global change. Echinoderms in a Changing World contains a selection of plenary and contributed papers, and a comprehensive presentation of abstracts of all oral papers and posters. The collection will be useful to all students of echinoderm biology, ecology and palaeontology, from undergraduate level to professional researchers.

Book Description
The dominant faunal elements in shallow Paleozoic oceans, echinoderms are important to understanding these marine ecosystems. Echinoderms (which include such animals as sea stars, crinoids or sea lilies, sea urchins, sand dollars, and sea cucumbers) have left a rich and, for science, extremely useful fossil record. For various reasons, they provide the ideal source for answers to the questions that will help us develop a more complete understanding of global environmental and biodiversity changes. This volume highlights the modern study of fossil echinoderms and is organized into five parts: echinoderm paleoecology, functional morphology, and paleoecology; evolutionary paleoecology; morphology for refined phylogenetic studies; innovative applications of data encoded in echinoderms; and information on new crinoid data sets.

Book Description
Echinoderms play an important ecological role in marine communities, especially in relation to food chains, occupying diverse trophic levels such as herbivores, carnivores, detritivores and omnivores in the marine environment. These animals feed on many different kinds of food but the majority eat only small particles of edible matter suspended in the water or lying as detritus on the sea bottom. Although echinoderms occur at all depths from the intertidal to the abyssal zones and are present throughout all of the world's oceans, their distribution is limited by the composition and topography of the sea-bed, by temperature and pressure differences according to locality and depth, and by salinity and food supply. This book discusses echinoderms and their habitual environments as well as their reproductive biology and the ecology in which they form their habitats.

Book Description
Echinoderms, including feather stars, seastars, brittle stars, sea urchins and sea cucumbers, are some of the most beautiful and interesting animals in the sea. They play an important ecological role and several species of sea urchins and sea cucumbers form the basis of important fisheries. Over 1000 species live in Australian waters, from the shoreline to the depths of the abyssal plain and the tropics to Antarctic waters. Australian Echinoderms is an authoritative account of Australia’s 110 families of echinoderms. It brings together in a single volume comprehensive information on the identification, biology, evolution, ecology and management of these animals for the first time. Richly illustrated with beautiful photographs and written in an accessible style, Australian Echinoderms suits the needs of marine enthusiasts, academics and fisheries managers both in Australia and other geographical areas where echinoderms are studied.

Book Description
With contributions from an impressive group of Argentinean and German oceanographers, this book examines classical ecological issues relating to marine ecosystems in the context of climate change. It paints a picture of marine ecology at the crossroads of global warming. The book examines the fundamentals of marine ecology: ecosystem stability, water quality, and biodiversity in the context of the changes taking place globally. It then reviews the major marine ecosystems in the same context, from the primary producers to the big marine mammals. The chapters cover primary consumers level, benthic communities, seaweeds assemblages and wetlands ecology, fisheries, and seabirds.

Book Description
Sea urchins and sea cucumbers are highly sought after delicacies growing in popularity globally. The demand for these species is rapidly outpacing natural stocks, and researchers and seafood industry personnel are now looking towards aquaculture as a means of providing a sustainable supply of these organism. Echinoderm Aquaculture is a practical reference on the basic biology and current culture practices for a wide range of geographically diverse echinoderm species. Echinoderm Aquaculture begins by examining the basic ecology and biology of sea urchins and sea cucumbers as well as the breadth of uses of these organisms as a source of food and bioactive compound. Subsequent chapters delineate the specific species of interest invarious geographic regions from around the world. Together, chapters provide a comprehensive coverage of culture practices. Echinoderm Aquaculture is a practical reference for researchers and industry personnel, and will serve as an invaluable resource to this rapidly growing segment of the aquaculture industry.

Book Description
Since 1972, scientists from all over the world working on fundamental questions of echinoderm biology and palaeontology have conferred every three years to exchange current views and results. The 11th International Echinoderm Conference held at the University of Munich, Germany, from 6-10 October 2003,continued this tradition. This volume comprises 95 submitted papers and 96 abstracts covering a wide spectrum from innovative student contributions to the lessons learnt from experienced specialists. The content of the contributions ranges from original research results to the latest synopses concerning a variety of topics, including visual sensing, larval cloning, mutable collagenous tissues, sea urchin aqua-culture, deuterostome phylogeny, palaeobiology and taphonomy.

Book Description
The extraxial-axial theory (EAT) and universal elemental homology (UEH) are often portrayed as mutually exclusive hypotheses of homology within pentaradiate Echinodermata. EAT describes homology upon the echinoderm bauplan, interpreted through early post-metamorphic growth and growth zones, dividing it into axial regions generally associated with elements of the ambulacral system and extraxial regions that are not. UEH describes the detailed construction of the axial skeleton, dividing it into homologous plates and plate series based on symmetry, early growth, and function. These hypotheses are not in conflict; the latter is rooted in refinement of the former. Some interpretive differences arise because many of the morphologies described from eleutherozoan development are difficult to reconcile with Paleozoic forms. Conversely, many elements described for Paleozoic taxa by UEH, such as the peristomial border plates, are absent in eleutherozoans. This Element recommends these two hypotheses be used together to generate a better understanding of homology across Echinodermata.
