The family Bulimulidae is a dominant land snail family in the Neotropics, with more than 1000 nominal taxa described. Revisionary work has only partially been done, but many genera need further revisionary work for which a sound taxonomic basis is needed. Type specimens for more than 400 taxa of this family are present in the Natural History Museum, London, U.K., and are documented in this paper. For each taxon the relevant literature is cited, type locality, label, the provenance of the specimens, and the current systematic position; photographs of nearly all type specimens and labels are also provided.
Ancient lakes are exceptional freshwater environments that have continued to exist for hundreds of thousands of years. They have long been recognized as centres of biodiversity and hotspots of evolution. During recent decades, speciation in ancient lakes has emerged as an important and exciting topic in evolutionary biology. The contributions in this volume deal with patterns and processes of biological diversification in three prominent ancient lake systems. Of these, the famous East African Great Lakes already have a strong tradition of evolutionary studies, but the two other systems have so far received much less attention. The exceptional biodiversity of the European sister lakes Ohrid and Prespa of the Balkans has long been known, but has largely been neglected in the international literature until recently. The rich biota and problems of its evolution in the two central lake systems on the Indonesian island of Sulawesi, in turn, have only lately started to draw scientific attention. This volume aims at deepening the awareness of the unusual biological diversity in ancient lakes in general, and of the role of these lakes as natural laboratories for the study of speciation and diversification in particular. It should stimulate further research that will lead to a better understanding of key evolutionary processes in these lakes, and to knowledge that might help in mitigating the deterioration of their diversity in the future.
This book offers a comprehensive study of species- and genus-level diversity and chorology of the global freshwater fauna to date. It gives a state of the art assessment of the diversity and distribution of Metazoa in the continental waters of the world.
The biological composition and richness of most of the Earth's major ecosystems are being dramatically and irreversibly transformed by anthropogenic activity. Yet, despite the vast areal extent of our oceans, the mainstay of research to-date in the biodiversity-ecosystem functioning arena has been weighted towards ecological observations and experimentation in terrestrial plant and soil systems. This book provides a framework for extending these concepts to a variety of marine systems. Marine Biodiversity and Ecosystem Functioning is the first book to address the latest advances in biodiversity-function science using marine examples. It brings together contributions from the leading scientists in the field to provide an in-depth evaluation of the science, before offering a perspective on future research directions for some of the most pressing environmental issues facing society today and in the future.
Here is a comprehensive review of the ecology of freshwater bivalves and gastropods worldwide. Robert Dillon discusses the ecology of these species in its broadest sense, including diet, habitat, and reproductive biology to emphasize the tremendous diversity of these freshwater invertebrates. He develops a new life history model that unifies them and reviews their population and community ecology, treating competition, predation, parasitism, and biogeography. Extensively referenced and synthesizing work from the nineteenth century through to the present day, this book includes original analyses that unify previous work into a coherent whole.
"Ponder and Lindberg provides a breathtaking overview of the evolutionary history of the Mollusca, effectively melding information from anatomy, ecology, genomics, and paleobiology to explore the depths of molluscan phylogeny. Its outstanding success is due to thoughtful planning, focused complementary contributions from 36 expert authors, and careful editing. This volume is a must for malacologists."—Bruce Runnegar, Department of Earth and Space Sciences, University of California, Los Angeles "Our understanding of the phylogeny and evolutionary history of the mollusca has been revolutionized over the past two decades through new molecular data and analysis, and reinvestigation of morphological characters. In this volume Ponder, Lindberg, and their colleagues do a wonderful job of integrating this work to provide new perspectives on the relationships of the major molluscan clades, their evolutionary dynamics, and their history. Particularly timely is the coverage of molluscan evo-devo and genomics."—Douglas H. Erwin, Curator of Paleozoic Invertebrates, National Museum of Natural History
