Geerat Vermeij wrote this "celebration of shells" to share his enthusiasm for those supremely elegant creations and what they can teach us about nature. Most popular books on shells emphasize the identification of species, but Vermeij uses shells as a way to explore major ideas in biology. How are shells built? How do they work? How did they evolve? The author lucidly and charmingly demonstrates how shells give us insights into the lives of animals in our own day as well as in the distant geological past.

Jocelyn Crane presents a survey of the members of the genus Uca, with special reference to their morphology, social behavior, and evolution. Her account is firmly based on numerous field studies along the world's warmer shores and on comparative work in laboratories and museums. Originally published in 1975. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.

The purpose of this book is twofold: on one hand, it gives a mathematical perspective of Daphnia which comprises studies focusing on introducing size-structured population dynamics models of Daphnia and their unification, as well as developing and analyzing mathematical models of size-structured population dynamics of several species of Daphnia. These include proving the well-posedness of the model and related regularity properties, determining the steady states and proving the principle of linearised stability and studying the (in)stability of the steady states. The mathematical perspective of Daphnia is written at a research level and it is intended for researchers in applied mathematics, differential equations, biomathematics, mathematical biology, mathematical ecology as well as graduate students in the above mentioned fields of research. The necessary background for reading the chapters is the knowledge of ordinary differential equations, partial differential equations, integral equations and functional analysis. On the other hand, this book also provides a biological perspective of Daphnia by focusing on topics such as: the swimming behaviour, inducible defense mechanisms in order to avoid predation, sexual reproduction, the use of Daphnia as a classroom organism and the role of Daphnia in ecotoxicological evaluations of contaminants. In addition, it contains several video movies attached to some chapters. The biological perspective of Daphnia is written at a research level and intended for researchers in biology, chemistry, ecology and environment as well as graduate students in the above-mentioned fields of research.

In this book, the authors discuss the structure, ecology and life cycle of crustaceans. Topics include the structure, development and evolution of crustacean eyes; the effect of gamma radiation on the extraction of chitosan from the exoskeleton of crustaceans; lipid transport and metabolism in crustaceans; and soft-bottom crustacean assemblages influenced by anthropogenic activities in the Arabian Gulf.

This book presents topical research in the study of the anatomy, habitat and ecological significance of crabs. Topics discussed in this compilation include the different species of crabs and viral susceptibility; distribution and habitat of cold water crab species on the Grand Bank of Newfoundland; behavioural differences in fiddler crabs; cellular cadmium transport in gills and hepatopancreas of the mangrove crab and invasive swimming crabs.

What is a crab? What significance do crabs play in the world? In Crab, Cynthia Chris discovers that these charming creatures are social by nature, creative problem-solvers, and invaluable members of the environments in which they live. Their formidable physical forms, their hard-to-harvest and quick-to-spoil flesh, and their sassy demeanour have inspired artists and writers from Vincent van Gogh to Jean-Paul Sartre. Cynthia Chris sketches vivid portraits of these animals, tracing the history of the crab through its ancient fossil record to its essential role in protecting its own habitats from the threat of climate change.

Krill, or euphausiids, a group of immense importance in marine ecosystems, comprises over 80 species, most of which are planktonic. Krill are widespread with species to be found in all the oceans of the world. Their numerical density in some regions increases their importance to marine ecosystems and has led to commercially successful krill harvesting.

This comprehensive volume, thoroughly edited by Inigo Everson, well known for his work in this area, comprises chapters written by internationally acknowledged experts. The contents include coverage of: sampling and distribution, population, aggregation, reproduction and the role of krill in the ecosystem. Further specific chapters include krill harvesting, products and details of management in Japanese, Canadian and Southern Ocean waters. Drawing on the experience in each, the ecosystem approach to management is discussed in detail and how it might be applied more widely for example in forage fisheries.

This most important volume draws together, for the first time, a vast amount of vital information for all those involved in work on these important marine organisms. Krill will be of great use to fisheries scientists, marine biologists and ecologists, oceanographers, zoologists and invertebrate biologists and all those involved in the commercial harvesting, exploitation and management of krill, world wide. Libraries in all aquatic and marine research stations and universities where marine and fisheries sciences are studied and taught should have multiple copies of this landmark publication on their shelves.
Contributions from internationally-recognised experts in the field.
Well-edited to provide an accessible and user-friendly book.
Krill are a key part of ocean ecosystems.

The Zoological Guide to Crustacea opens by providing an update on the cave crustacean decapods from Mexico, because in the last thirty years several species have been described. Mexico has diverse cave environments according to cave origin, such as: karstic caves, volcano caves with freshwater habitats and anchialine caves with marine and brackish habitats. The following study focuses on a total of 2,700 Artemia franciscana collected at the Al Wathba Reserve between December 2017 and May 2018, which were examined for the presence of larval helminths by direct microscopy of glycerin mounted specimens. Of these, 341 (= 12.6%) specimens contained different species of the Hymenopepididae and Progynotaeniidae families. The penultimate study investigates whether the non-marine ostracod Heterocypris incongruens can detect and react to chemical compounds derived from a predator and from injured conspecifics. The closing study demonstrates the diversity of larval phases and their importance to lobster populations and fisheries, and provides a summary of larval developmental patterns and behaviors and their potential impacts on larval dispersal and lobster demographic connectivity.

This is a contribution to the conservation of members of the family Cambaridae. This book is focused on the evaluation of geographic changes caused by landscape scale and land use change that has impacted the ecology of North American crayfish species. The book includes chapters on geographic distributions, conservation strategies, and effects of contaminants on crayfish structure and function. Contributors include a variety of students associated with the Editor, as well as original contributions from the Editor's colleagues. From the conceptual frameworks to the case studies, Geographic Distribution, Ecological Impact, and Conservation Strategies for North American Crayfish will provide important considerations to assist in the conservation and protection of crayfish, with emphasis on stressors and actions necessary to protect and restore crayfish habitats and populations. This book is necessary for environmental and natural resource managers, researchers, and governmental agencies tasked with the protection, restoration, and management of wildlife populations.

The authors are two of the best taxonomic experts in crustacean decapods, who have established the actual taxonomy and systematic of numerous and important groups of decapods. They have introduced new views and approaches on the taxonomy, phylogeny and biogeography of these crustaceans. This international edition adds diagnoses and identification keys to all world families and genera: this information simply doesn't exist in any other book. During the last decade, the world register of marine species (WORMS) has created the list of known species and promoted the publication of numerous compilations on crustacean decapods. However, except specialists of each taxa, very few colleagues can identify correctly the new families and genera - there are no keys to these new groups. This book is the first to contain these world keys and is therefore a life rope for students, marine biologists, taxonomists and naturalists. The mixture of taxonomic line drawings, color illustrations and images of real-life specimens is extremely helpful for identification, especially when working in the field.

Crustaceans adapt to a wide variety of habitats and ways of life. They have a complex physiological structure particularly with regard to the processes of growth (molting), metabolic regulation, and reproduction. Crustaceans are ideal as model organisms for the study of endocrine disruption and stress physiology in aquatic invertebrates. This book is an overview of the extensive research that has taken place over the recent years on issues of crustacean reproduction.

In this revision of the calanoid copepod family Heterorhabdidae, 7 genera and 59 species are recognized, and 25 species are described as new. Included are keys to the genera and descriptions and illustrations of all species. A hypothesis of phylogenetic relationships is presented, and the geographic distribution of the species is discussed.

American Indians worshiped them as creators of the world, Napoleon ate them to celebrate his victories, Swedes have them shipped in from halfway around the world, and for Louisiana's Cajuns the humble crawfish is the centerpiece of cuisine, a symbol of ethnic pride, a staple commodity for thriving business ventures, and an inextricable part of folklore.

Research and interviews spice this delightful book that details the relationship between crawfish and humans--from antiquity to the New York markets of the 1880s; from Depression-era pauper's feast to gourmet entree of the 1980s Cajun cooking craze; from spring afternoon pastime to modern aquaculture agribusiness.

To get the reader's mouth watering, more than two dozen recipes from those who know crawfish best--both famous chefs and crawfishers--are interspersed throughout. Sections offer advice on catching, buying, handling, cooking, and, for those who wish to simplify their encounters with crawfish, ordering tasty dishes in restaurants. Included are also a bibliographical essay, an index to recipes, and a list of sources for spices, paraphernalia, and airfreight shipments of crawfish.

A comprehensive treatment of the taxonomy and geographical distribution of the Euchaetidae, a typically carnivorous marine Calanoid family with a worldwide distribution in the whole depth range. The author redefines the family and its two genera. Species groups recognized in each genus and a total of 75 species found are described in detail and illustrated with figures. Geographical range is determined for most of the species. Keys are presented for identification of the species groups and the species in each group.
