Annelids (the segmented worms) exist in a remarkably diverse range of mostly marine but also freshwater and terrestrial habitats, varying greatly in size and form. Annelida provides a fully updated and expanded taxonomic reference work which broadens the scope of the classic Polychaetes (OUP, 2001) to encompass wider groups including Clitellata (comprising more than a third of total annelid diversity), Sipuncula, and Thalassematidae (formerly Echiura). It reflects the enormous amount of research on these organisms that has burgeoned since the millennium, principally due to their use as model organisms to address wider and more general evolutionary and ecological questions. Beginning with a clear introduction to the phylum and an outline of annelid taxonomy, this authoritative text describes their collection, the methods to ensure their optimal preservation, and an overview of anatomy with its relevant terminology. The core of the work comprises 77 fully up-to-date taxonomic chapters, informed by anatomy and the latest molecular phylogenomic evidence and carefully organised based on a new, robust phylogenetic hypothesis. Lavishly illustrated throughout with hundreds of previously unpublished high-resolution colour images and SEM micrographs, the sheer beauty and diversity of the annelids is nowhere better presented. Annelida is the definitive reference work for annelid biologists, whilst being of interest to a broader audience of invertebrate zoologists, systematists, and organismal biologists.

Poole Harbour is protected and recognised, nationally and internationally, for its ecological importance. However, it has also been classified as polluted and eutrophic. These twin designations – protected yet polluted – exemplify the condition of many estuaries, making Poole Harbour an ideal subject for elucidating the circumstances behind this apparent paradox. The outcome of a conference entitled ‘Spotlight on Poole Harbour: Environment & Economics’ organised by the Poole Harbour Study Group, this book comprises four main parts. Part I, ‘Background’, provides a broad introduction to the harbour in terms of its pre-historical and historical significance for human communities and gives a conceptual overview of its modern character and uses. Part II, ‘Ecology’, contains chapters ranging from plankton to marine mammals. The subsequent parts focus on industries dependent on the biological and chemical ‘ecological services’ of the estuary: Part III, ‘Fisheries’, covers recreational and commercial fishing and aquaculture, examining economic value and key shellfish species. Part IV, ‘Water Quality’, addresses those industries that require the harbour to remediate various effluents, as well as some of the environmental consequences and noteworthy efforts to reduce such impacts. Part V, ‘Conclusion’, by the editors examines certain general shortcomings of environmental legislation and regulation manifest in the case of Poole Harbour. A central concern throughout is the question of sustainable development in coastal and marine contexts, making this wide-ranging study relevant well beyond the bounds of its primary geographical focus.

Biology of Oysters offers scientific insights into the structure and function of oysters. Written by an expert in the field of shellfish research, this book presents more than 50 years of empirical research literature. It provides an understanding of the edible oysters, in order to equip students and researchers with the background needed to undertake further investigations on this model marine invertebrate. - Presents empirical research findings in context with the relevant theory and its expression in computer models - Includes information on studies of other bivalve species such as mussels and clams - Offers a description of the whole organism to provide a frame of reference for further research - Includes research developments in the phylogeny, physiology and ecology of oysters

A comprehensive account of Polychaetes in Australia. Based on nearly 2400 references, the authors reveal the wealth of diversity in the largely unknown world of these worm groups, in terms of their morphology, behaviour, reproduction and significance in marine ecosystems.
