This part B of the fourth volume of The Crustacea contains chapters on: ● Crustaceans in the Biosphere ● Crustaceans and Mankind ● Crustaceans in Art ● Orders Lophogastrida, Stygiomysida, and Mysida [collectively known as Mysidacea] As evident from the number 4B tagged to this volume, vol. 4 as originally planned had to be split into two fascicles, 4A and 4B, simply because of the numbers of pages covered by the various contributions meant for volume 4. The chapters in this book grew out of those in the French edition volumes 7(II) and 7(III)(A). Overall, this constitutes the seventh tome published in this English series, viz., preceded by volumes 1 (2004), 2 (2006), 9A (2010), 9B (2012), 3 (2012), and 4A (2013). Readers/users should note that from vol. 4A onward we have had to abandon publishing the chapters in the serial sequence as originally envisaged by the late Prof. J. Forest, because the various contributions, i.e., both the updates and the entirely new chapters, have become available in a more or less random order.

As evident from the number 4A tagged to this volume, vol. 4 as originally planned had to be split into two fascicles, 4A and 4B, simply because of the numbers of pages covered by the various contributions meant for volume 4. The present volume, then, comprises the fourth part in the series The Crustacea, i.e., the revised and updated texts from the Traité de Zoologie – Crustacea. The chapters in this book grew out of those in the French edition volume 7(II). The exception is chapter 49, which has been newly conceived; it was never published in French. Overall, this constitutes the sixth tome published in this English series, viz., preceded by volumes 1 (2004), 2 (2006), 9A (2010), 9B (2012), and 3 (2012). Readers/users should note that we have had to abandon publishing the chapters in the serial sequence as originally conceived by the late Prof. J. Forest, because the various contributions, i.e., both the updates and the entirely new chapters, have become available in a more or less random order. This fourth volume, part A, of The Crustacea contains chapters on: • Genetic variability in Crustacea • Class Cephalocarida • Class Remipedia • Subclass Hoplocarida: order Stomatopoda • Superorder Syncarida

This volume, 9C, in two parts, covers the Brachyura. With the publication of the ninth volume in the Treatise on Zoology: The Crustacea, we departed from the sequence one would normally expect. Some crustacean groups, mainly comprising the Decapoda, never had a French version produced, and the organization and production of these “new” chapters began independently from the preparation of the other chapters and volumes. Originally envisioned to encompass volume 9 of the series, it quickly became evident that the depth of material for such a volume must involve the printing of separate fascicles. The new chapters have now been completed, and the production of volume 9 was started while volumes 3 through 8 were (and in part still are) in preparation; with this vol. 9C-I & II this volume 9 is now concluded; vols. 1-5 have also been published and vols. 6-8 are being prepared.

Identification and Ecology of Freshwater Arthropods in the Mediterranean Basin covers the entire Mediterranean basin, including parts of Europe, Asia, Africa and the Mediterranean islands, but excluding other biogeographic locations with Mediterranean climates located outside the region. The book provides an extensive description of the taxonomy and ecology of aquatic arthropods encountered in lentic and lotic habitats, as well as in less studied underground and estuarine habitats. It offers expanded taxonomic identification keys to major groups of arthropods with a description of their ecology and distribution. Keys for insects include aquatic larval stages and water-dwelling adults of Coleoptera and Heteroptera. Additional sections focus on taxa that can be encountered in adjacent brackish and estuary ecosystems as long as the taxon primarily occurs in freshwaters. This is a much-needed, comprehensive resource on the taxonomy and ecology of freshwater arthropods with an introduction to recent molecular tools for identifications. It will be particularly useful for freshwater ecologists, limnologists, environmentalists and students in the ecological sciences. - Presents taxonomic keys to genera and species to the majority of aquatic arthropod families - Provides coverage of all freshwater ecosystems of the Mediterranean basin, with case studies and examples - Includes numerous photographs of the aquatic arthropods described in the chapters - Covers the ecology and taxonomy of organisms living in more traditionally studied lakes and streams as well as in less studied underground and estuarine habitats

Thorp and Covich's Freshwater Invertebrates, Volume 5: Keys to Neotropical and Antarctic Fauna, Fourth Edition, covers inland water invertebrates of the world. It began with Ecology and General Biology, Volume One (Thorp and Rogers, editors, 2015) and was followed by three volumes emphasizing taxonomic keys to general invertebrates of the Nearctic (2016), neotropical hexapods (2018), and general invertebrates of the Palearctic (2019). All volumes are designed for multiple uses and levels of expertise by professionals in universities, government agencies, private companies, and graduate and undergraduate students. - Includes zoogeographic coverage of the entire Neotropics, from central Mexico and the Caribbean Islands, to the tip of South America - Provides identification keys for aquatic invertebrates to genus or species level for many groups, with keys progressing from higher to lower taxonomic levels - Contains terminology and morphology, materials preparation and preservation, and references

This multi-author, six-volume work summarizes our current knowledge on the developmental biology of all major invertebrate animal phyla. The main aspects of cleavage, embryogenesis, organogenesis and gene expression are discussed in an evolutionary framework. Each chapter presents an in-depth yet concise overview of both classical and recent literature, supplemented by numerous color illustrations and micrographs of a given animal group. The largely taxon-based chapters are supplemented by essays on topical aspects relevant to modern-day EvoDevo research such as regeneration, embryos in the fossil record, homology in the age of genomics and the role of EvoDevo in the context of reconstructing evolutionary and phylogenetic scenarios. A list of open questions at the end of each chapter may serve as a source of inspiration for the next generation of EvoDevo scientists. Evolutionary Developmental Biology of Invertebrates is a must-have for any scientist, teacher or student interested in developmental and evolutionary biology as well as in general invertebrate zoology. This second volume on ecdysozoans covers all animals commonly known as crustaceans. While “Crustacea” is currently not considered a monophylum, it still appears reasonable to combine its representatives in one joint volume due to their numerous shared morphological and developmental characteristics. Because of the huge variation in the amount of available developmental data between the various taxa, only the Dendrobranchiata, Astacida and Cirripedia are treated in individual chapters. The remaining data on crustacean development, usually incomplete and often patchy, is presented in two chapters summarizing early development and larval diversity, thereby also taking into account the data on fossil larval forms.

This fourth volume, part B, of The Crustacea contains chapters on: ● Crustaceans in the Biosphere ● Crustaceans and Mankind ● Crustaceans in Art ● Orders Lophogastrida, Stygiomysida, and Mysida [collectively known as Mysidacea]

Emphasis is placed on the elaborate cuticular matrices in insects and crustaceans, spider and insect silks, sialomes of phytophagous and blood-feeding arthropods as well as on secretions of male and female accessory glands. Focus is placed largely on insects, due to the extensive body of published research that in part is the result of available whole genome sequences of several model species (in particular Drosophila melanogaster) and accessible ESTs for other species. Such advances have facilitated fundamental insights into genomic, proteomic and molecular biology-based physiology. This new volume contains comprehensive contributions on extracellular composite matrices in arthropods. The building blocks of such matrices are formed in and secreted by single layered epithelial cells into exterior domains where their final assembly takes place.Additionally, the unique mechanical properties of natural biocomposites like chitin/chitosan, the crustacean mineralized exoskeleton, the pliant protein resilin or insect and spider silks, have inspired basic and applied research that yield sophistical biomimetics and structural biocomposite hybrids important for future industrial and biomedical use. In summary, this book provides an invaluable vast source of basic and applied information for a plethora of scientists as well as textbook for graduate and advanced undergraduate students.

This volume, 9A, contains the material on the euphausiaceans, amphionidaceans, and many of the decapods (dendrobranchiates, carideans, stenopodideans, astacidans, and palinurans).
