Book Description
The scientific understanding of arthropod phylogeny and evolution has changed significantly in recent decades. One of the most momentous alterations involved crustaceans, which are not a monophyletc group, but are part of a larger group along with insects: Pancrustacea. The old ideas surrounding crustacean evolution have served scientists well for many years; it is now time to turn toward new research by embracing the results derived from investigations conducted largely within this century. For example, new definitions have arisen from sources across several fields of study, and Frederick R. Schram and Stefan Koenemann have created a book that explores paleobiodiversity and the diversity of modern body plans. Developments within ontogenetic studies continue to generate remarkable insights into crustaceomorph evolution in regard to patterns of embryology and a revolution in the application of development genetics. Phylogeny techniques of analysis and new sources of data derived from molecular sequencing and genetic studies have forced scientists to consider new hypotheses concerning the interrelationships of all the pancrustaceans, both the crustaceomorphs and Hexapoda. Yet, some fossil groups still remain enigmatic (Thylacocephala). Despite this, research into fossils (even if incompletely understood) fills in gaps of our knowledge of paleobiodiversity, and it's useful for many things, including analyzing the origin and early evolution of Hexapoda. Evolution and Phylogeny of Pancrustacea demonstrates the use of multiple alternative hypotheses and other techniques through the well-executed presentation of diverse data sources involving Pancrustacea. Readers are left with clues to great mysteries, including the possible pathways of evolution within marine arthropods.

Book Description
Decapod crustaceans, shrimps, crabs, prawns and their allies are highly visible and important members of marine environments. They are among the most charismatic of marine animals, inhabiting beaches, rocky shores and the deep sea, hiding under stones, burrowing in the sediment and nestling in among algae and many other microhabitats. However, most are difficult to identify by the specialist and amateur naturalist alike. Marine Decapod Crustacea explains the anatomical features necessary for differentiating taxa and includes diagnoses and identification keys to all 189 families and 2121 genera of marine Decapoda. Many decapods have vivid colours, which are showcased in a selection of spectacular photographs of many representative species. This volume provides an entry to the literature for taxonomists, naturalists, consultants, ecologists, teachers and students wanting to identify local faunas and understand this diverse group

Biodeterioration of Wooden Cultural Heritage

Book Description
Since prehistoric times and throughout the course of human evolution, wood has been an integral part of all civilizations. Wooden Cultural Heritage can be found worldwide, providing valuable information on the social and economic context of human history. Nonetheless, as a natural cellulosic material, wood shows low resistance to biodeterioration and thus wooden Cultural Heritage often fails to escape decomposition in both aquatic and terrestrial ecosystems. This book provides a comprehensive overview on the biodeterioration of wooden Cultural Heritage and describes the decay mechanisms of key organisms and microorganisms encountered in aquatic and terrestrial ecosystems. Cultural Heritage professionals, researchers and academics may explore within this book the associations between deteriogens, habitats and decay, which will assist them to understand wood biodeterioration and design effective prevention, mitigation and remediation strategies. The book presents case studies around the world to demonstrate the impact of biogenic deterioration on wooden Cultural Heritage and illustrates mechanisms and patterns in order to be a useful handbook of decay diagnosis. Lastly, by adopting a holistic approach to wood decay, basic concepts of wood technology, ecology, and deteriogens' biology are introduced, permitting readers of different scientific backgrounds to easily comprehend wood biodeterioration.

Book Description
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

Book Description
"As a young and impetuous gradate student, I thought that sorting out the phylogeny of crustaceans would simply take but a little time and concerted effort to eventually reveal the truth. Everyone could then agree and further research would proceed apace. How naïve I was. First of all, I had never heard of Kurt Gödel's incompleteness theorems and hence the impossibility of achieving such an end. But even so, what progress we might have made turned out to take longer than anyone could have imagined, and the effort would be immense involving many people and a number of laboratories-and that task still continues. What no one could foresee in the 1960s was that the focus of everyone's attentions would completely transform. Traditional pure anatomy would be augmented with more sophisticated developmental genetic work. Concurrent with that effort molecular sequencing would become a remarkably effective tool. And with these new sources of data, the concept of "crustaceans" would yield to a new construct-Pancrustacea-within which the arthropods that we referred to by the name of "Crustacea" became a series of monophyletic smaller groups that mark a paraphyletic transition from a mandibulate ancestor all the way up to a crown group that few in the 1960s expected-Hexapoda emerged within the pancrustaceans"--

Book Description
Tropical Deep-Sea Benthos is a series dedicated to the inventory and description of the deep-sea fauna of the world, with special emphasis on their most extensive--but remote and least-explored--habitats: the Indo-West Pacific. Growing out of marine expeditions undertaken by the French National Museum of Natural History and the Institut de Recherche pour le Développement, the series continues to present many new, strange, and sometimes colorful invertebrates. The present volume presents results from recent expeditions within the New Caledonian Exclusive Economic Zone, reporting ninety-eight species (including fifty-seven new species) of corals from the Stylasteridae family and one new calcified species of hydrozoa from the family Hydractiniidae. Including numerous seamounts, submarine ridges, and small islands, New Caledonia's deep-sea benthos are ideal habitat for stylasterids, making it the most species-rich marine region in the world for this taxon.
