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
Serpulid polychaetes are a unique and highly specialised group of marine segmented worms that have adapted to inhabiting self-secreted calcareous tubes attached to a wide range of hard substrates. These animals are found across all depths and habitats of the world’s oceans, and some form mutually beneficial associations with live corals. The genus Hydroides is of special concern and importance, as it is not only the largest, but also one of the most ecologically and economically important groups of marine invertebrates because it includes notorious biofoulers and common bioinvaders that travel around the world hitchhiking on ships’ hulls. This is the first fully illustrated guide to this notorious serpulid genus of calcareous tubeworms, providing a comprehensive diagnostic treatment of all known species of the genus Hydroides. This important reference provides reliable identification tools to distinguish Australian tubeworms from potential alien invaders that constantly arrive from overseas and threaten Australia’s maritime transport, trade and mariculture.

Book Description
This book is the second volume in a series of 4 volumes in the Handbook of Zoology series treating morphology, anatomy, reproduction, development, ecology, phylogeny, systematics and taxonomy of polychaetous Annelida. In this volume a comprehensive review of a few more derived higher taxa within Sedentaria are given, namely Sabellida, Opheliida/Capitellida as well as Hrabeiellidae. The former comprise annelids possessing a body divided into two more or less distinct regions or tagmata called thorax and abdomen. Here two groups of families are united, the spioniform and sabelliform polychaetes. Especially Spionidae and Sabellidae are speciose families within this group and represent two of the largest annelid families. These animals live in various types of burrows or tubes and all possess so-called feeding palps. In one group these appendages are differentiated as grooved feeding palps, whereas in the other they may form highly elaborated circular tentacular crowns comprising a number of radioles mostly giving off numerous filamentous pinnulae. Often additionally colourful, the latter are also received the common names "feather-duster worms", "flowers of the sea", "Christmas-tree worms". Opheliida/Capitellida including five families of truly worm-like annelids without appendages represents the contrary. Their members burrow in soft bottom substrates and may be classified as non-selective deposit feeders. Molecular phylogenetic analyses have shown that Echiura or spoon worms, formerly regarded to represent a separate phylum, are members of this group. Last not least Hrabeiellidae is one out of only two families of oligochaete-like terrestrial polychaetes and for this reason received strong scientific interest.

Book Description
The textbook entitled Tropical Ecology of Southeast Asia – The Indonesian Archipelago unfolds in its 5 major chapters with 20 subchapters on more than 500 pages, with more than 300 figures, the basic principles of ecology with examples mainly coming from the Indonesian Archipelago. After an introduction describing the geography, geology and climate of the region, the second chapter is dedicated to marine and freshwater ecosystems. Chapters on the functional ecology of seagrass beds, coral reefs, open ocean and deep sea are followed by information on lotic and lentic freshwater ecosystems. In chapter III ecotones and special ecosystems of the achipelago are in focus. The ecology and ecosystems of shore and tidal flats, mangroves, estuaries and soft bottom shores, caves, small islands, grasslands and savannas are decribed. The forest ecosystems with beach forest, tropical lowland evergreen rainforest, some special forest systems and mountain forests form the contents of chapter IV. The final chapter V is dealing with agroecosystems and human ecology. The main focus in this chapter is ricefield ecology, landuse systems and social ecology, including the advent of man and the development and expansion of man influencing this achipelago. An extended glossary and bibliography is added as well as tables of abbreviations, conversion factors, international system of units and measurements or SI and a geological time table and systematics. The index gives assess to important keywords and relevant information spread thoughout the contents of the book. The textbook will certainly be useful to teachers, lecturers and their students at university and college level. It also gives an overview about insular ecology of the vast Indonesian archipelago to any interested person or working ecologist. * Focuses on the tropical ecology and insular ecosystems and biodiversity of Indonesia, as well as the agroecology of humid tropics * Contains over 300 figures * Provides an extended glossary and bibliography, as well as tables of abbreviations, converstion factors, international system of units and a geological time table * Easy-to-use index gives access to important keywords used throughout the text

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.
