Their story began 500 million years ago, but we only started to get to know them in 1746, when Linné described the first ostracod species. Vividly portraying the freshwater ostracods, this comprehensive reference work gathers the knowledge gained during some 250 years, but which to date has remained scattered throughout the literature. It starts with an introduction to the class Ostracoda with a special focus on freshwater ostracods and highlights practical methods in their study. The systematic part includes an introduction to all families; identification keys for all subfamilies, genera and species; diagnoses for each subfamily and genus; and lists of synonyms and distribution of species. The text is richly illustrated with distribution maps, line drawings of key generic characteristics, and numerous SEM photographs. Serving as an excellent starting point for all further research on freshwater ostracods, it can be widely used not only by ostracodologists, but also by crustaceologists, evolutionists and ecologists.
This publication is composed of papers presented at an International Symposium on Athalassic (Inland) Salt Lakes, which was hosted by the University of Adelaide, South Australia, during a week in October 1979. The genesis of the Symposium was at the Copenhagen Congress of the International Association of Limnology (S.1. L.) where it was noted that a number of papers concerned with inland saline lakes were distributed throughout sessions in such a way as to make it difficult to attend all of them. A number of participants at the Congress felt that the ecology of salt lakes had greater homogeneity or cohesiveness than this sort of distribution would suggest, and it was decided that a symposium on salt lakes be held. The symposium was the first under the aegis of the S.l. L. to be held in Australia, and it was very well attended, with participants coming from many countries. The week long programme produced a number of lively and interesting sessions on all aspects of athalassic saline lakes. Participants stayed on after the Symposium for an expedition to Lake Eyre, in the nQrth of South Australia, and were given one of the best of all possible introductions to the Australian environment.
Wetlands are among the world’s most valuable and most threatened habitats, and in these crucially important ecosystems, the invertebrate fauna holds a focal position. Most of the biological diversity in wetlands is found within resident invertebrate assemblages, and those invertebrates are the primary trophic link between lower plants and higher vertebrates (e.g. amphibians, fish, and birds). As such, most scientists, managers, consultants, and students who work in the world’s wetlands should become better informed about the invertebrate components in their habitats of interest. Our book serves to fill this need by assembling the world’s most prominent ecologists working on freshwater wetland invertebrates, and having them provide authoritative perspectives on each the world’s most important freshwater wetland types. The initial chapter of the book provides a primer on freshwater wetland invertebrates, including how they are uniquely adapted for life in wetland environments and how they contribute to important ecological functions in wetland ecosystems. The next 15 chapters deal with invertebrates in the major wetlands across the globe (rock pools, alpine ponds, temperate temporary ponds, Mediterranean temporary ponds, turloughs, peatlands, permanent marshes, Great Lakes marshes, Everglades, springs, beaver ponds, temperate floodplains, neotropical floodplains, created wetlands, waterfowl marshes), each chapter written by groups of prominent scientists intimately knowledgeable about the individual wetland types. Each chapter reviews the relevant literature, provides a synthesis of the most important ecological controls on the resident invertebrate fauna, and highlights important conservation concerns. The final chapter synthesizes the 15 habitat-based chapters, providing a macroscopic perspective on natural variation of invertebrate assemblage structure across the world’s wetlands and a paradigm for understanding how global variation and environmental factors shape wetland invertebrate communities.
Ostracods belong to a group of microfossils found in nearly all types of aquatic environments. These microcrustaceans, characterized by a bivalved, calcitic carapace, are used to reconstruct ancient environments. For example, they can help to provide information on palaeoclimates, palaeogeography, the formation of deep oceans, sea level changes, etc. This book endeavours to bring about a greater understanding of their usefulness in many aspects of geological sciences, and provides suggestions for future research. It is principally intended for the non-specialist, and shows many applications of ostracods to help solve geological problems and phenomena. Topics reviewed assume no prior knowledge of palaeontology, and thus terminology is kept simple. There is an exhaustive index, and an appendix supplying additional references on significant sources of information on ostracods. This book aims to deliver information on ostracods to those people not usually interested in the literature of palaeontology and also to awaken an interest in the Ostracoda by referring to more specialized articles published elsewhere.
