Book Description
The book is a taxonomic guide to serpulid polychaetes (including the subfamily Spirorbinae) of the Arctic Ocean. Taxonomic keys include 37 serpulid spesies described and illustrated in detail. It starts with a description of serpulid morphology and includes a comprehensive glossary. Taxonomic treatment of species includes basic synonymy, references, and brief differential diagnoses. Information is also available on species reproduction, geographical distribution, and habitats in the Arctic Basin. Species illustrations are presented as light and scanning electron microscopy micrographs, photos of live specimens and line drawings. The book is based on extensive (over 600 samples) material collected all over the Arctic Ocean and deposited in Russia, Iceland, Germany, Norway, and Australia. The guide is based on the same material as Rzhavsky et al. (2014) “Calcareous tubeworms (Polychaeta, Serpulidae) of the Arctic Ocean”, but it has another concept and target user: it is a simplified and lavishly illustrated field guide for identification definition of calcareous tubeworms in the field and laboratory. Detailed synonymy and taxonomic discussions are excluded. This guide is intended for undergraduate and graduate students, educators and naturalists as well as invertebrate zoologists, marine ecologists, and environmental consultants.

Book Description
In this Special Issue, we address the state of the art of the systematics of the main annelid groups and the improvements in the diversity they hold, with special emphasis on the latest discoveries in well-studied areas, expeditions to unsurveyed areas or environments, or the use of novel techniques that allow for the improvement of biodiversity knowledge. We are hoping that this Special Issue will provide a platform facilitating a review of current knowledge on the subject, identifying current research problems, as well as indicating directions and research trends for the future.

Book Description
The fascination of the Annelida to scientists lies in the beauty of their structures and the functionality of their body plan, the tremendous adaptive radiation which has made it possible for these animals to colonize almost all marine, limnic and terrestrial biotopes. In doing so they have evolved a great variety of life forms, and their reproduction and development are correspondingly diverse, with many modes and patterns unique in the animal kingdom. In this special volume recent progress in this broad research area is presented by 26 specialists, in general through surveys or treatments of selected examples. Some of them review important annelid taxa such as the Nereididae, Syllidae, Spionidae, Cirratulidae, Clitellata, and Pogonophora; others analyse reproductive and developmental structures and phenomena in annelids, e.g. segmental organs, sex pheromones, oogenesis, mating systems, sperm types, life cycles, larval settlement, cleavage and symmetry of embryos, or discuss controversial approaches to annelid systematics. The book will be of interest to all zoologists who work with annelids as well as to embryologists and other researchers in reproductive biology.

Book Description
Cold-water coral ecosystems figure the formation of large seabed structures such as reefs and giant carbonate mounds; they represent unexplored paleo-environmental archives of earth history. Like their tropical cousins, cold-water coral ecosystems harbour rich species diversity. For this volume, key institutions in cold-water coral research have contributed 62 state-of-the-art articles on topics from geology and oceanography to biology and conservation, with some impressive underwater images.

Book Description
Animal life, now and over the past half billion years, is incredibly diverse. Describing and understanding the evolution of this diversity of body plans - from vertebrates such as humans and fish to the numerous invertebrate groups including sponges, insects, molluscs, and the many groups of worms - is a major goal of evolutionary biology. In this book, a group of leading researchers adopt a modern, integrated approach to describe how current molecular genetic techniques and disciplines as diverse as palaeontology, embryology, and genomics have been combined, resulting in a dramatic renaissance in the study of animal evolution. The last decade has seen growing interest in evolutionary biology fuelled by a wealth of data from molecular biology. Modern phylogenies integrating evidence from molecules, embryological data, and morphology of living and fossil taxa provide a wide consensus of the major branching patterns of the tree of life; moreover, the links between phenotype and genotype are increasingly well understood. This has resulted in a reliable tree of relationships that has been widely accepted and has spawned numerous new and exciting questions that require a reassessment of the origins and radiation of animal life. The focus of this volume is at the level of major animal groups, the morphological innovations that define them, and the mechanisms of change to their embryology that have resulted in their evolution. Current research themes and future prospects are highlighted including phylogeny reconstruction, comparative developmental biology, the value of different sources of data and the importance of fossils, homology assessment, character evolution, phylogeny of major groups of animals, and genome evolution. These topics are integrated in the light of a 'new animal phylogeny', to provide fresh insights into the patterns and processes of animal evolution. Animal Evolution provides a timely and comprehensive statement of progress in the field for academic researchers requiring an authoritative, balanced and up-to-date overview of the topic. It is also intended for both upper level undergraduate and graduate students taking courses in animal evolution, molecular phylogenetics, evo-devo, comparative genomics and associated disciplines.
