Book Description
This volume presents a synthesis of basic biological and conservation data for more than 30 species of sturgeons (Acipenseridae), paddlefishes (Polyodontidae) and their fossil allies in the order Acipenseriformes. Since the Jurassic, the four families of sturgeon-like fish have been restricted to the Holarctic, where until very recently they flourished in most major river systems. Today, however, virtually all species of sturgeons and paddlefishes face difficult conservation issues. Papers in the first section of this volume examine paleontology, systematics, evolution and basic biology of Acipenseriformes. The second section of this volume details current conservation status for most of the world's living species of Acipenseriformes. These papers mark the first attempt to make such a global review of recent data from across the northern hemisphere. The emerging picture is discouraging, for negative anthropogenic impacts range from overfishing to water pollution, to dams and water diversion projects, and all species are threatened to some degree. The third section of the volume considers specific human impacts and responses to conservation issues. These include: the Aral Sea ecological disaster and its impact on native sturgeons; a review of methods for restoring sturgeon populations; the use of molecular techniques in developing conservation strategies; the extreme sensitivity of sturgeons and paddlefishes to overfishing; and the history of a recently convicted caviar poaching ring. The volume's summary reviews the status of all extant species and notes future directions for research on behavior, ecology and population biology that could lead to better co-ordinated international conservation efforts.

Book Description
This open access book surveys the frontier of scientific river research and provides examples to guide management towards a sustainable future of riverine ecosystems. Principal structures and functions of the biogeosphere of rivers are explained; key threats are identified, and effective solutions for restoration and mitigation are provided. Rivers are among the most threatened ecosystems of the world. They increasingly suffer from pollution, water abstraction, river channelisation and damming. Fundamental knowledge of ecosystem structure and function is necessary to understand how human acitivities interfere with natural processes and which interventions are feasible to rectify this. Modern water legislation strives for sustainable water resource management and protection of important habitats and species. However, decision makers would benefit from more profound understanding of ecosystem degradation processes and of innovative methodologies and tools for efficient mitigation and restoration. The book provides best-practice examples of sustainable river management from on-site studies, European-wide analyses and case studies from other parts of the world. This book will be of interest to researchers in the field of aquatic ecology, river system functioning, conservation and restoration, to postgraduate students, to institutions involved in water management, and to water related industries.

Book Description
Modern North American sturgeons and paddlefish are the result of 100 million years of evolution. Once an integral part of aboriginal culture, their numbers were decimated by overfishing and habitat destruction during the past two centuries. This book details the extensive science aimed at helping these remarkable species recover from the brink of extinction, and describes the historical, biological, and ecological importance of North American sturgeon and paddlefish. The text is enhanced by photographs and detailed line drawings. This comprehensive volume will be an invaluable resource for researchers, educators, and consultants, in academic and government settings, who work to further scientific understanding of these fishes. No other single compilation has documented current information in such detail.

Book Description
Six species of sturgeons are native to the Danube River Basin. The need for conservation action is urgent, given that recent observations in the Lower Danube indicate that all sturgeon populations are near extinction. Due to the high commercial value of sturgeon products, in particular caviar, the pressure from proaching and illegal trade remains intense. These species will not survive unless fishing practices are greatly addressed, and both migration routes and habitats for all life-cycle stages are protected. Through national action and international co-ordination, this action plan aims to secure viable populations of all Danube sturgeon species by sustainable management and restoration of their natural habitats and migratory corridors

Book Description
The book aims at synthesizing our current knowledge of Acipenser sturio and its management. This species, one of the most widespread sturgeon species all over Western Europe ranging from the Black Sea to the Baltic, is now on the verge of extinction. Major aspects of its biology and management, including mismanagement, are provided in a historic perspective. Similarly, the changes in the restoration programs (in situ and ex situ) initiated in France and Germany are presented. As the species occurred in sympatry with Acipenser oxyrinchus in Germany and Poland and very recently in France as well, a brief outlook on restoration-management programs of A. oxyrinchus are also provided for both North America and Northern European countries, namely Germany and Poland. As conservation-restoration actions go beyond scientific issues, non-governmental stakeholders and marine professional fishermen’s organizations have also been asked to contribute, and the key role of a French-German cooperation plan is underlined. A part of the book is devoted to perspectives. Illustrations of the European sturgeon, mainly in photographs, but also in stamps and paintings, are presented.

Book Description
Growing human populations and higher demands for water impose increasing impacts and stresses upon freshwater biodiversity. Their combined effects have made these animals more endangered than their terrestrial and marine counterparts. Overuse and contamination of water, overexploitation and overfishing, introduction of alien species, and alteration of natural flow regimes have led to a 'great thinning' and declines in abundance of freshwater animals, a 'great shrinking' in body size with reductions in large species, and a 'great mixing' whereby the spread of introduced species has tended to homogenize previously dissimilar communities in different parts of the world. Climate change and warming temperatures will alter global water availability, and exacerbate the other threat factors. What conservation action is needed to halt or reverse these trends, and preserve freshwater biodiversity in a rapidly changing world? This book offers the tools and approaches that can be deployed to help conserve freshwater biodiversity.

Book Description
IUCN's 5th World Parks Congress (2003) concluded that parks should not exist as unique islands, but need to be planned and managed as an integral part of the broader landscape. Ecological networks provide an operational model for conserving biodiversity that is based on ecological principles and allow a degree of human use of the landscape. This publication illustrates the development of several ecological networks around the world, demonstrating their benefits both for conservation and sustainable development.
