DOWNLOAD EBOOKOctopus Biology and Ecology is an all-in-one resource that explains early life history stages, including age and growth maturation, distribution, migration, diet, predators and parasites related to these mollusks. Octopods are becoming a strong source of protein, with information on the species becoming more and more important to fisheries. This reference offers detailed information on the most economically important octopods in the world and addresses the management and future forecasting of octopod fisheries. Special attention is given to octopods in highly variable coastal environments as they constitute a particular challenge. Octopod populations (together with other cephalopod groups) have increased worldwide, suggesting that these commercially relevant mollusks will benefit from the conditions of the oceans of tomorrow (e.g., global warming and decreased competition and predator pressures). This is a complete resource for aquatic scientists, marine biologists, researchers, cephalopod biologists, cephalopod ecologists, fisheries and aquaculture scientists, regulators and students. - Provides a thorough overview of the biodiversity of octopuses - Presents detailed information about 21 different species - Includes a profound analysis of past, present, and future trends in octopus research

DOWNLOAD EBOOKPaleontology and Neontology of Cephalopods examines information that throws new light on the evolution of coleoids. This book is part of a multivolume work, The Mollusca, which attempts to provide comprehensive treatment of major areas of molluscan research. The Mollusca is intended to serve several disciplines—zoology, biochemistry, physiology, and paleontology. It will prove useful to researchers and to all others with interests in mollusks. The book begins with a review of the main features of cephalopod evolution. This is followed by separate chapters on the evolution of the gladius in coleoids; the buccal mass of Cephalopoda; beaks of living coleoid Cephalopoda; cephalopod hooks; statoliths of cephalopods; buoyancy and locomotion in recent cephalopods; and evolution of the cephalopod brain and cephalopod statocyst. Subsequent chapters deal with the photophore structure and evolution within the Enoploteuthinae; the interrelationships of genera within the Ommastrephidae; evolutionary pathways traversed by the cephalopod family Cranchiidae; the cephalopod fauna of the European Mediterranean; and the evolution of recent cephalopods.

DOWNLOAD EBOOKPhylonyms is an implementation of PhyloCode, which is a set of principles, rules, and recommendations governing phylogenetic nomenclature. Nearly 300 clades - lineages of organisms - are defined by reference to hypotheses of phylogenetic history rather than by taxonomic ranks and types. This volume will document the Real World uses of PhyloCode and will govern and apply to the names of clades, while species names will still be governed by traditional codes. Key Features Provides clear regulations for implementing new guidelines for naming lineages of organisms incorporates expressly evolutionary and phylogenetic principles Works with existing codes of nomenclature Eliminates the reliance on rank-based classification in favor of phylogenetic relationships Related Titles: Rieppel, O.

DOWNLOAD EBOOKReproduction of Marine Invetebrates, Volume IV Molluscs: Gastropods and Cephalopods describes the wide range of structural complexity and diverse modes of reproduction of gastropods and cephalopods. Each chapter discusses the asexual reproduction, sexual reproduction capacity, and developmental stages of different group of gastropods and cephalopods, including prosobranchia, opisthobranchia, pulmonata, nautiloidea, decapoda, and octopoda. Gastropods are among the most conspicuous sea animals, and species of limpets, snails, and slugs are found in all marine habitats. Cephalopods are active and important marine predators, ranging from archaic nautiloids to more recent pelagic decapods and benthic octopods, which are often considered to be one of the apexes of invertebrate evolution. They are all gonochoric and reproduce only by sexual means. All have intricate courtship behavior and derived developmental patterns. Marine biologists and researchers, scientists, and developmental biologists will find this book invaluable.
Marine Biodiversity of Costa Rica, Central America

DOWNLOAD EBOOKLife began in the sea, and even today most of the deep diversity of the planet is marine. This is often forgotten, especially in tropical countries like Costa Rica, renowned for their rain forests and the multitude of life forms found therein. Thus this book focusing on marine diversity of Costa Rica is particularly welcome. How many marine species are there in Costa Rica? The authors report a total of 6,777 species, or 3. 5% of the world’s total. Yet the vast majority of marine species have yet to be formally described. Recent estimates of the numbers of species on coral reefs range from 1–9 million, so that the true number of marine species in Costa Rica is certainly far higher. In some groups the numbers are likely to be vastly higher because to date they have been so little studied. Only one species of nematode is reported, despite the fact that it has been said that nematodes are the most diverse of all marine groups. In better studied groups such as mollusks and crustaceans, reported numbers are in the thousands, but even in these groups many species remain to be described. Indeed the task of describing marine species is daunting – if there really are about 9 million marine species and Costa Rica has 3. 5% of them, then the total number would be over 300,000. Clearly, so much remains to be done that new approaches are needed. Genetic methods have en- mous promise in this regard.
