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 in both humans and livestock. Volume 1 looks at non-Bilaterians (sponges, cnidarians, placozoans). The focus on sponge biology has recently been on symbiosis, nutrient uptake, and sensory biology. The section on cnidarians covers biomineralization, the nervous system, and development. The biology of placozoans is described in depth, including the role of neuropeptides in feeding. Volume 2 and covers crustacean physiology and diverse physiological topics, ranging from molting, respiration, water balance, biomineralization, bioreceptors, and temperature regulation to the land adaptation of terrestrial crustaceans. Echinoderms and annelids are covered in Volume 3.

They are also medically relevant as parasites that cause major diseases of both humans and livestock. Chapters on crustacean physiology are grouped in this volume and cover diverse physiological topics ranging from moulting, respiration, water balance, biomineralization, bioreceptors, and temperature regulation to the land adaptation of terrestrial crustaceans. The chapters are comprehensive and add new knowledge to crustacean biology. Volume 1 looks at non-bilaterians (sponges, cnidarians, placozoans) while echinoderms and annelids are covered in Volume 3.

"Volume 1 looks at Bilateria (sponges, cnidarians, placozoans). The focus on sponge biology has recently been on symbiosis, nutrient uptake, and sensory biology. The research on cnidarians primarily has been on biomineralization, the nervous system, and development as well as neuropeptide biology of placozoans involved in feeding and neuropeptides in cnidarians"--

Animals rely on sensory input from their environment for survival and reproduction. Depending on the importance of a signal for a given species, accuracy of sensory coding might vary from pure detection up to precise coding of intensity, quality and temporal features of the signal. Highly sophisticated sense organs and related central nervous sensory pathways can be of utmost importance for animals in a complex environment and when using advanced communication systems. In sensory systems different anatomical and physiological features have evolved to optimally encode behaviourally relevant signals at the level of sense organs and central processing. The wide range of organizational complexity, in combination with their relatively simple and accessible nervous systems, makes invertebrates excellent models to study general sensory coding principles. The contributions to this e-book illustrate on one hand particular features of specific sensory systems, and on the other hand indicate not only common features of sensory coding across invertebrate phyla, but also similar processing principles of complex stimuli between different sensory modalities. The chapters show that the extraction of behaviourally relevant signals from all environmental stimuli, as well as the detection of low intensity signals and the analysis of temporal features can be similar across sensory modalities, including olfaction, vision, mechanoreception, and heat perception.

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 two important areas in echinoderm biology. It includes an important review of juxtaligamental cells, which may regulate the mechanical properties of connective tissue. Annelid physiology is discussed (neurobiology of locomotion in leeches, regeneration, reproduction) as is neuro-endocrine-immune response. Volume 1 looks at non-bilaterians (sponges, cnidarians, placozoans), while Volume 2 focuses on crustacean physiology, covering diverse physiological topics ranging from moulting, respiration, water balance, biomineralization, bioreceptors, and temperature regulation to the land adaptation of terrestrial crustaceans.
