Book Description
An illustrated guide to the sweeping diversity of crustacean larval forms. Winner of the CHOICE Outstanding Academic Title of the Choice ACRL Crustaceans—familiar to the average person as shrimp, lobsters, crabs, krill, barnacles, and their many relatives—are easily one of the most important and diverse groups of marine life. Poorly understood, they are among the most numerous invertebrates on earth. Most crustaceans start life as eggs and move through a variety of morphological phases prior to maturity. In Atlas of Crustacean Larvae, more than 45 of the world's leading crustacean researchers explain and illustrate the beauty and complexity of the many larval life stages. Revealing shapes that are reminiscent of aliens from other worlds—often with bizarre modifications for a planktonic life or for parasitization, including (in some cases) bulging eyes, enormous spines, and aids for flotation and swimming—the abundant illustrations and photographs show the detail of each morphological stage and allow for quick comparisons. The diversity is immediately apparent in the illustrations: spikes that deter predators occur on some larvae, while others bear unique specializations not seen elsewhere, and still others appear as miniature versions of the adults. Small differences in anatomy are shown to be suited to the behaviors and survival mechanisms of each species. Destined to become a key reference for specialists and students and a treasured book for anyone who wishes to understand "the invertebrate backbone of marine ecosystems," Atlas of Crustacean Larvae belongs on the shelf of every serious marine biologist.

Book Description
More than two thirds of all living organisms described to date belong to the phylum Arthropoda. But their diversity, as measured in terms of species number, is also accompanied by an amazing disparity in terms of body form, developmental processes, and adaptations to every inhabitable place on Earth, from the deepest marine abysses to the earth surface and the air. The Arthropoda also include one of the most fashionable and extensively studied of all model organisms, the fruit-fly, whose name is not only linked forever to Mendelian and population genetics, but has more recently come back to centre stage as one of the most important and more extensively investigated models in developmental genetics. This approach has completely changed our appreciation of some of the most characteristic traits of arthropods as are the origin and evolution of segments, their regional and individual specialization, and the origin and evolution of the appendages. At approximately the same time as developmental genetics was eventually turning into the major agent in the birth of evolutionary developmental biology (evo-devo), molecular phylogenetics was challenging the traditional views on arthropod phylogeny, including the relationships among the four major groups: insects, crustaceans, myriapods, and chelicerates. In the meantime, palaeontology was revealing an amazing number of extinct forms that on the one side have contributed to a radical revisitation of arthropod phylogeny, but on the other have provided evidence of a previously unexpected disparity of arthropod and arthropod-like forms that often challenge a clear-cut delimitation of the phylum.

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
Taphonomic bias is a pervasive feature of the fossil record. A pressing concern, however, is the extent to which taphonomic processes have varied through the ages. It is one thing to work with a biased data set and quite another to work with a bias that has changed with time. This book includes work from both new and established researchers who are using laboratory, field and data-base techniques to characterise and quantify the temporal and spatial variation in taphonomic bias. It may not provide all the answers but it will at least shed light on the right questions.

Book Description
This section of the Handbook of Zoology is intended as a comprehensive and exhaustive account of the biology of the taxa Gastrotricha, Nematoda, Nematomorpha, Priapulida, Kinorhyncha, Loricifera, Gnathostomulida, Micrognathozoa, Rotifera, Seisonida and Acanthocephala, covering all relevant topics such as morphology, ecology, phylogeny and diversity. The series is intended to be a detailed and up-to-date account of these taxa. As was the case with the first edition, the Handbook is intended to serve as a reliable resource for decades. Many of the taxa of this volume are comparatively unknown to many biologists, despite their diversity and importance for example in meiofaunal communities (Gastrotricha, Rotifera, Gnathostomulida), their fascinating recent discoveries (Loricifera and Micrognathozoa), their importance as parasites (many nematodes, Nematomorpha, Acanthocephala) and their importance for evolutionary questions (e.g. Priapulida, Gastrotricha). The groups covered range from those poor in species (such as Micrognathozoa with 2 known species) to the species-rich and diverse Nematoda and their ca. 20.000 described species. While each taxon is covered by one chapter, nematodes are treated in several chapters dedicated to their structural, taxonomic and ecological diversity.
