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.

In the last decades a remarkable renaissance has materialized in insect morphology, mainly triggered by the development of new cutting-edge technologies. This is an exciting time for biological synthesis where the mysteries and data derived from genomes can be combined with centuries of data from morphology and development. And, now, more than ever, detailed knowledge of morphology is essential to understanding the evolution of all groups of organisms. In this "age of phylogenomics" researchers rely on morphological data to support molecular findings, test complex evolutionary scenarios, and for placing fossil taxa. This textbook provides an in-depth treatment of the structures and the phylogeny of the megadiverse Hexapoda. The first part presents an up-to-date overview of general insect morphology with detailed drawings, scanning electron micrographs, and 3-D reconstructions. Also included is a chapter covering innovative morphological techniques (e.g., µ-computer tomography, 3-D modeling), brief treatments of insect development and phylogenetic methods, and a comprehensive morphological glossary. The second part is of a modern synthesis of insect systematics that includes taxon-specific morphological information for all Orders. The work is an invaluable reference for students and researchers working in all facets of biology and is a must for evolutionary biologists. A detailed understanding of morphology is essential in unraveling phylogenetic relationships and developing complex evolutionary scenarios. Increasingly researchers in phylogenomics are re/turning to morphological data to support their findings, while the development of new cutting-edge technologies has further increased interest in this growing field. This definitive handbook provides an in-depth treatment of insect morphology. The first part presents an up-to-date overview of insect morphology with detailed drawings, brilliant scanning electron micrographs and 3-D reconstructions as interactive PDFs. This is complemented by a chapter on innovative morphological techniques (e.g., µ-computer tomography, 3-D modeling) and a comprehensive morphological glossary. The second part treats the state of the art in insect systematics and includes taxon-specific morphological information for all orders. Systematics are treated formally, with for example the arguments for relationships ("apomorphies") always listed explicitly. The work is a useful reference for students and researchers working in different fields of biology and a must for those dealing with insects from an evolutionary perspective.

"Ce livre fait la synthèse des concepts de la systématique et des méthodes employées, jusqu’aux plus modernes à l’œuvre aujourd’hui. Ce livre raconte l'histoire complexe et les révolutions de cette science, tant méthodologiques que conceptuelles. La systématique, ou science de la classification, est une science historique qui intègre les données de la morpho-anatomie, de l’embryologie, de la physiologie et de la paléontologie. Elle connut deux révolutions conceptuelles, dont l’une est toujours à l’œuvre. Ses méthodes ont radicalement changé, et ses résultats récents bouleversent des schémas de pensée solidement ancrés dans les esprits. L’histoire complexe de la systématique, et les renversements tant méthodologiques que conceptuels qui l’ont accompagnée, la rendent difficile à maîtriser. Sous un angle zoologique, ce livre raconte cette histoire en détail et explique clairement ce que la systématique présente doit au passé, mais aussi comment elle doit désormais se couper d’une partie de son passé."--

This monograph is the second of a series treating the hypotrichs, a major part of the spirotrichous ciliates. The urostyloids are characterised by a zigzag-arrangement of the ventral cirri. Like the first part of the series, the Oxytrichidae, it summarises the morphological, morphogenetic, faunistic, and ecological data from the past 230 years, scattered in more than 1300 references from all over the world. Dichotomous keys lead to 36 genera and subgenera comprising 153 species illustrated by more than 2100 figures, including original ones. The treatise offers taxonomists, cell biologists, and

Lagomorphs are a mammalian order which includes rabbits, hares and pikas. They are distributed throughout the world and are of both scientific and public interest as they are classified between endangered and pest species. In addition, some have a high economic value as important game species. In the last few decades, a huge amount of information was made available to the scientific community and resulted in remarkable advances on all aspects of Lagomorph biology. However, this information is dispersed in multiple scientific and non-scientific journals. This book provides an updated synthesis of the current knowledge on Lagomorph biology.
