Available in PDF, EPUB and Kindle. Book excerpt: The study of coelenterates is now one of the most active fields of invertebrate zoology. There are many reasons for this, and not everyone would agree on them, but certain facts stand out fairly clearly. One of them is that many of the people who study coelenterates do so simply because they are interested in the animals for their own sake. This, however, would be true for other invertebrate groups and cannot by itself explain the current boom in coelenterate work. The main reasons for all this activity seem to lie in the considerable concentration of research effort and funding into three broad, general areas of biology: marine ecology, cellular-developmental biology and neurobiology, in all of which coelenterates have a key role to play. They are the dominant organisms, or are involved in an important way, in a variety of marine habitats, of which coral reefs are only one, and this automatically ensures their claims on the attention of ecologists and marine scientists. Secondly, the convenience of hydra and some other hydroids as experimental animals has long made them a natural choice for a variety of studies on growth, nutrition, symbiosis, morphogenesis and sundry aspects of cell biology. Finally, the phylogenetic position of the coelenterates as the lowest metazoans having a nervous system makes them uniquely interesting to those neurobiologists and behaviorists who hope to gain insights into the functioning of higher nervous systems by working up from the lowest level.

Available in PDF, EPUB and Kindle. Book excerpt: Reproduction of Marine Invertebrates, Volume I: Acoelomate and Pseudocoelomate Metazoans is a collection of papers that deals with the evolution of reproductive mechanisms and behavior in marine invertebrates. This collection starts with terminologies and basic events in marine invertebrate reproduction, including the method of estimating sexual reproductive activity, as well as the timing and patterns involved. The book notes that temperatures, salinities, or food availability should be favorable when the young are produced and when they are developing. One paper shows that the reproductive rhythm is dynamic and in some species is latitude-dependent. Other papers discuss the reproductive cycles of different marine invertebrates such as the Porifera, Cnidaria, Nemertinea, and Nematoda. These papers include topics on asexual reproduction, regeneration, sexual reproduction, and development, and then explain in detail the development of certain invertebrates from their kinorhynchs state (embryonic), to the molting stages, juvenile stages, then to adulthood. This book can be useful for marine biologists, marine ecologists, and students involved in marine biological and physical sciences.

Download or read book Lifestyles and Feeding Biology written by Martin Thiel and published by Oxford University Press. This book was released on 2015-03-16 with total page 593 pages. Available in PDF, EPUB and Kindle. Book excerpt: This second volume in the Natural History of the Crustacea series examines how crustaceans-the different body shapes and adaptations of which are described in volume 1-make a living in the wide range of environments they inhabit, and how they exploit food sources. The contributions in the volume give synthetic overviews of particular lifestyles and feeding mechanisms, and offer a fresh look at crustacean life styles through the technological tools that have been applied to recent crustacean research. These include SEM (scanning electron microscope) techniques, micro-optics, and long-term video recordings that have been used for a variety of behavioral studies. The audience will include not only crustacean biologists but evolutionary ecologists who want to understand the diversification of particular life styles, ecologists who follow the succession of communities, biogeochemists who estimate the role of crustaceans in geochemical fluxes, and biologists with a general interest in crustaceans.
