Describes an extraordinary endemic radiation of hydrobioid snails in the Mekong River (MR). The monophyletic radiation involving the subfamily Triculinae, 3 tribes, 11 genera, & 92 species, is larger than contemporaneous endemic freshwater gastropod faunas of centers of endemism, such as lakes Tanganyika & Baikal. The study addresses the issue of how higher taxa arise by analyzing the series of adaptive radiations within the MR Triculinae. The worldwide family Hydrobiidae is polyphyletic & includes 2 distinct lineages, the Hydrobiidae sensu stricto & the Pomatiopsidae with the subfamilies Pomatiopsidae & Triculinae. The differences between the two families were masked by convergence in shell, radula, penis, & operculum. Maps & illus.

This volume provides individual treatments of the major molluscan taxa. Each chapter provides an overview of the evolution, phylogeny and classification of a group of molluscs, as well as more specific and detailed coverage of their biology (reproduction, feeding and digestion, excretion, respiration etc.), their long fossil record and aspects of their natural history. The book is illustrated with hundreds of colour figures. In both volumes, concepts are summarised in colour-coded illustrations. Key selling features: Comprehensively reviews molluscan biology and evolutionary history Includes a description the anatomy and physiology of anatomical systems Up to date treatment with a comprehensive bibliography Reviews the phylogenetic history of the major molluscan lineages

Radiations, or Evolution in Action We have just celebrated the “Darwin Year” with the double anniversary of his 200th birthday and 150th year of his masterpiece, “On the Origin of Species by means of Natural Selection”. In this work, Darwin established the factual evidence of biological evolution, that species change over time, and that new organisms arise by the splitting of ancestral forms into two or more descendant species. However, above all, Darwin provided the mechanisms by arguing convincingly that it is by natural selection – as well as by sexual selection (as he later added) – that organisms adapt to their environment. The many discoveries since then have essentially con?rmed and strengthened Darwin’s central theses, with latest evidence, for example, from molecular genetics, revealing the evolutionary relationships of all life forms through one shared history of descent from a common ancestor. We have also come a long way to progressively understand more on how new species actually originate, i. e. on speciation which remained Darwin’s “mystery of m- teries”, as noted in one of his earliest transmutation notebooks. Since speciation is the underlying mechanism for radiations, it is the ultimate causation for the biological diversity of life that surrounds us.

The authors argue that the growth pattern and form of the colony in many bryozoans is an adaptive strategy rather than a stable genetic character. "Bryozoan Evolution is profusely illustrated and has a bibliography of over 400 titles. It will find an appreciative audience of paleontologists, invertebrate zoologists, and ecologists thanks to its innovative and detailed evaluations of the roles of ecology, adaptive and functional morphology, life histories, biomechanics, developmental constraints, and chance on the evolution of the marine taxa of this speciose group."—Russel L. Zimmer, Science "This book is an excellent source of information on the functional morphology and variety of colonial architecture in bryozoans, very well illustrated, and worth reading at least twice."-Robert L. Anstey, Paleobiology "Even as one of the converted, I found the book a stimulating combination of paleobiology and ecology. In many ways it is a 'teaser'-the authors suggest a number of interesting hypotheses, and can test only some of them. Perhaps most important, McKinney and Jackson provide a plethora of fascinating ideas and examples that demonstrate the potential of this group of animals, and that should stimulate more work."-Michael S. Keough, TREE "This stimulating book is sure to promote further interest in bryozoans. It will appeal to biologists and paleontologists alike."-Paul Taylor, Times Higher Education Supplement

The definitive resource on the biology and evolution of freshwater mollusks. There are more species of freshwater mollusks—well over 5,000—than all the mammal species of the world. Freshwater mollusks are also arguably the most endangered fauna on the planet. Yet few references exist for researchers, shell enthusiasts, and general readers who are interested in learning more about these fascinating creatures. In Freshwater Mollusks of the World, Charles Lydeard and Kevin S. Cummings fill that void with contributions from dozens of renowned mollusk experts. Touching on 34 families of freshwater gastropods (snails) and 9 families of freshwater bivalves (mussels and clams), each chapter provides a synthesis of the latest research on the diversity and evolutionary relationships of the family. The book also includes • a look at how evolving DNA sequencing data techniques help shed light on mollusk taxonomy • distribution maps of each family's biogeographic locales • a representative photo and distribution map for each of the freshwater mollusk families • the latest information on each family's conservation status—and how to reverse the habitat destruction, modification, and pollution that threatens it • a discussion of the ecological and economic damages caused by invasive mollusk species, as well as their role as disease vectors Mollusks provide us with amazing biogeographical insights: their ancient fossil record goes back over 500 million years, and their distribution patterns are a reflection of past continental and climate changes. The only comprehensive summary of systematic and biodiversity information on freshwater mollusk families throughout the world, this reference is a must for malacologists, limnologists, ichthyologists, stream ecologists, biogeographers, and conservation biologists.
