Rescue of Sturgeon Species in the Ural River Basin by Viktor Lagutov Pdf
While almost every aspect of society-nature interactions can be treated as an environmental security issue, the threats to human societies originating from inadequate freshwater management constitute one of the most wi- spread and pressing problems. For thousands of years rivers and river valleys have been the cradle of human civilizations. Rivers have provided not only food and freshwater, but also shelter and means of transportation, and they are still an essential component in every national and regional economy. In turn, growing needs of human societies, accompanied by growing abilities, have caused significant river alterations and ecosystem changes that have resulted in river contamination, biodiversity loss and general riverine ecosystem degradation. The extinction of sturgeon species is one of the most eloquent examples of the negative and irreversible influence of human society on river e- systems. The sturgeon, sometimes called the “living fossil” or living “dinosaur” of the fish world, is known to have lived since the time of the dinosaurs, for at least 250 million years, and is currently on the verge of extinction solely due to anthropogenic impacts.
Riverine Ecosystem Management by Stefan Schmutz,Jan Sendzimir Pdf
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.
Sturgeons and Paddlefish of North America by G.T.O LeBreton,F. William H. Beamish,Scott R. McKinley Pdf
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.
Biodiversity, Conservation and Environmental Management in the Great Lakes Basin by Eric Freedman,Mark Neuzil Pdf
The Great Lakes Basin in North America holds more than 20 percent of the world's fresh water. Threats to habitats and biodiversity have economic, political, national security, and cultural implications and ramifications that cross the US-Canadian border. This multidisciplinary book presents the latest research to demonstrate the interconnected nature of the challenges facing the Basin. Chapters by U.S. and Canadian scholars and practitioners represent a wide range of natural science and social science fields, including environmental sciences, geography, political science, natural resources, mass communications, environmental history and communication, public health, and economics. The book covers threats from invasive species, industrial development, climate change, agricultural and chemical runoff, species extinction, habitat restoration, environmental disease, indigenous conservation efforts, citizen engagement, environmental regulation, and pollution.Overall the book provides political, cultural, economic, scientific, and social contexts for recognizing and addressing the environmental challenges faced by the Great Lakes Basin.
Biology, Conservation and Sustainable Development of Sturgeons by Ramón Carmona,Alberto Domezain,Manuel García Gallego,José Antonio Hernando,Fernando Rodríguez,Manuel Ruiz-Rejón Pdf
Sturgeons are considered “living fossils”, sharing many morphological and biological features with ancestral fish. Furthermore, sturgeons are of the utmost interest from an economic perspective, not only for the caviar but for the flesh. However, the wild populations of the majority of the species are at serious risk of extinction all over the world. So, it is urgent to develop strategies for both farming culture and conservation and recovery in natural habitats. This book provides a comprehensive view of the biology and sustainable development of sturgeons putting emphasis on the Southern Europe autochthonous species such as Acipenser nacarii and Acipenser sturio that share geographical distribution. Other relevant species (such as Huso huso, A. oxyrhinchus, A. ruthenus, A. stellatus) and areas (Germany, Russia, North America) are also considered. The contents are organised in three sections: Taxonomy and Biogeography (including the morphological and genetic analyses that clarify the taxonomy and phylogeny of sturgeons, focused on those from Southern Europe), Biology and Aquaculture (where several aspects of the developmental biology, feeding, and reproduction are considered in relation to the improvement of sturgeon farming), and Recovery and Conservation (that collates and analyses different recovery research actions, the ecology of the rivers for restoration as well as the problems related to the trade of caviar).

Biology and Conservation of the European Sturgeon Acipenser sturio L. 1758 by Patrick WILLIOT,Eric Rochard,Nathalie Desse-Berset,Frank Kirschbaum,Jörn Gessner Pdf
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.

Action Plan for the Conservation of Sturgeons (Acipenseridae) in the Danube River Basin by Jürg Bloesch Pdf
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
The Great Lake Sturgeon by Nancy A. Auer,Dave Dempsey Pdf
The first book of its kind to explore this magnificent creature, this collected volume captures many aspects of the remarkable Great Lakes sturgeon, from the mythical to the critically real. Lake sturgeon are sacred to some, impressive to many, and endangered in the Great Lakes. A fish whose ancestry reaches back millions of years and that can live over a century and grow to six feet or more, the Great Lakes lake sturgeon was once considered useless, then overfished nearly to extinction. Though the fish is slowly making a comeback thanks to the awareness-raising efforts of Native Americans, biologists, and sturgeon supporters, it remains to be seen if conservation and stewardship will continue to the degree this remarkable animal deserves. Blending history, biology, folklore, environmental science, and policy, this accessible book seeks to reach a broad audience and tell the story of the Great Lakes lake sturgeon in a manner as diverse as its subject.
