Crustaceans
Anyone who attempts to study crustaceans soon realizes that there are many science fields involved. As a major subphylum of Arthropods—the largest phylum in the animal kingdom—crustaceans exhibit an extraordinary diversity of taxa, shapes, physiology and styles of life. These invertebrates play key ecological roles in all aquatic environments, while only a few species are adapted to sub-aerial and humid environments. Their evolutionary success is not only due to a wide set of morphological and biological adaptations, but also because of some key features, e.g., their peculiar endocrinology. In addition, crustaceans are characterized by chemical and optical sensors deserving attention bec...
Morphology, Molecules, Evolution and Phylogeny in Polychaeta and Related Taxa
Recently, evidence has been accumulated which shows that some of the groups formerly regarded as independent "phyla" such as Pogonophora (now recognized as Siboglinidae), Echiura, Myzostomida and perhaps Sipuncula, are most probably nothing else than greatly modified Annelida. The extreme morphological diversity found especially in Polychaeta displays the plasticity of a simple segmented organisation that basically is nothing else but a serial repetition of identical units. Thus, annelids are highly important to our understanding of fundamental questions about morphological and adaptive diversity, as well as clarifying evolutionary changes and phylogenetic relationships. The book aims to summarize our knowledge on Polychaetes polychaetes and their allies and gives an overview of recent advances gained by studies that employed conventional and modern methods plus, increasingly and importantly, the use of molecular markers and computer-assisted kinship analyses. It also reflects the state of art in polychaete sciences and presents new questions and controversies. As such it will significantly influence the direction of research on Polychaeta and their related taxa.
Reproductive Strategies and Developmental Patterns in Annelids
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.
Invertebrate Pathology
This book assembles an international team of the leading specialists in the field to review the main diseases and pathologic manifestations of all the major invertebrate groups, whilst describing their emergence in contexts such as climate change and global food security.
Frontiers in Invertebrate Physiology: A Collection of Reviews
This new 3-volume set provides informative reviews on the physiology of sponges, cnidarians, round and flat worms, annelids, echinoderms, and crustaceans, advancing our knowledge of the physiology of these major invertebrate groups (Phyla). Invertebrates exhibit the largest number of species and occupy virtually every conceivable ecological niche. They are economically important in food chains, they recycle organic waste, and they are crucial pollinators of plants and sources of food. They are also medically relevant as parasites that cause major diseases of both humans and livestock. Echinoderms and annelids are covered in Volume 3. The volume looks at temporary adhesion and regeneration as...
