Book Description
Loss of biodiversity is among the greatest problems facing the world today. Conservation and the Genetics of Populations gives a comprehensive overview of the essential background, concepts, and tools needed to understand how genetic information can be used to conserve species threatened with extinction, and to manage species of ecological or commercial importance. New molecular techniques, statistical methods, and computer programs, genetic principles, and methods are becoming increasingly useful in the conservation of biological diversity. Using a balance of data and theory, coupled with basic and applied research examples, this book examines genetic and phenotypic variation in natural populations, the principles and mechanisms of evolutionary change, the interpretation of genetic data from natural populations, and how these can be applied to conservation. The book includes examples from plants, animals, and microbes in wild and captive populations. This second edition contains new chapters on Climate Change and Exploited Populations as well as new sections on genomics, genetic monitoring, emerging diseases, metagenomics, and more. One-third of the references in this edition were published after the first edition. Each of the 22 chapters and the statistical appendix have a Guest Box written by an expert in that particular topic (including James Crow, Louis Bernatchez, Loren Rieseberg, Rick Shine, and Lisette Waits). This book is essential for advanced undergraduate and graduate students of conservation genetics, natural resource management, and conservation biology, as well as professional conservation biologists working for wildlife and habitat management agencies.

Book Description
Understanding the reproductive physiology and endocrinology of fishes is essential for captive maturation and seed production in the field of aquaculture. Studying the spermatology of fishes is a comparatively new focus in aquaculture, which has emerged as an important area of fish research over the past two decades. In this regard, the cryopreservation of fish gametes is a crucial aspect. Moreover, energetics studies of gametes have become essential, considering the loss of vigour in the spermatozoa after cryopreservation.The latest development in this context is the cryopreservation of spermatogonial stem cell, which is also covered in the book, along with detailed information on embryo cryopreservation in fishes and crustaceans. The role of cryopreservation in conservation programmes is another important aspect, one that will especially interest biologists.This book addresses central issues in fish gamete cryopreservation and breeding, while also reviewing the history of cryopreservation. Its most unique feature is the breadth of its coverage, from basic information on reproduction in fishes, to such advanced topics as embryo cryopreservation. Chiefly intended as a handy troubleshooting guide, the book represents a valuable resource for research students in related fields.

Book Description
As the human population increases and nations become more industrialized, the habitat and water quality required for the survival of fish continues to decline. In addition to these environmental factors, fish populations are directly or potentially affected by harvesting, enhancement programs and introgression with hatchery-propagated or transgenic fish. To our knowledge no other scientific meeting has been assembled to consider the breadth of the problem, to review the technology that is presently available for the preservation of the germ plasm of salmonid stocks and to identify the scientific advances that are required to overcome the problems. Because many salmonids have spawning grounds within the confines of a specific region or county but will spend a large portion of their life cycle within the territorial waters of other countries or in the open ocean, the preservation of unique genes or gene pools in these animals requires international cooperation. This scientific meeting has provided a forum in which to discuss the problems, evaluate the present methods or technology for addressing the problems and suggest new directions or innovations that need to be implemented. During this meeting we limited our discussion to salmonid fishes. However, the general conclusions about the factors that affect the population dynamics of fish stocks and the technical aspects concerning the preservation of germ plasm will be applicable to other fish species.

Book Description
Written as a stand-alone textbook for students and a useful reference for professionals in government and private agencies, academic institutions, and consultants, Ecology and Conservation of Fishes provides broad, comprehensive, and systematic coverage of all aquatic systems from the mountains to the oceans. The book begins with overview discussions on the ecology, evolution, and diversity of fishes. It moves on to address freshwater, estuarine, and marine ecosystems and identifies factors that affect the distribution and abundance of fishes. It then examines the adaptations of fishes as a response to constraints posed in ecosystems. The book concludes with four chapters on applied ecology to discuss the critical issues of management, conservation, biodiversity crises, and climate change. Major marine fisheries have collapsed, and there are worldwide declines in freshwater fish populations. Fishery scientists and managers must become more effective at understanding and dealing with resource issues. If not, fish species, communities, and entire ecosystems will continue to decline as habitats change and species are lost. Ecology and Conservation of Fishes has taken a historical and functional approach to explain how we got where we are, providing old and new with a better foundation as ecologists and conservationists, and most importantly, it awakens senses of purpose and need. Past management practices are reviewed, present programs considered, and the need for incorporating principles of applied ecology in future practices is emphasized.

Book Description
Biodiversity protection encompasses key aspects directly related to the sustainability of our food systems: BFA provides a diverse and heterogenous biological basis for diverse and resilient production systems, for the pollination of cultures, for increased diversity of food, and is strongly linked to local and indigenous knowledge on local crops and breeds acknowledged as cultural heritage. This study examines the existence of data collection, monitoring systems, and conservation initiatives as well as legislation and policies related to biodiversity for food and agriculture in the three following regions: (1) Central Asia, (2) the South Caucasus countries, Turkey, Belarus and Ukraine and (3) the Western Balkan countries and the Republic of Moldova. From this study, it appears that none of the three studied regions currently have any solid monitoring schemes for agricultural biodiversity, nor do they have a strong legal framework for protecting farmers’ rights to seeds that would allow them, amongst other things, to maintain biodiversity. Conservation actions, policies, and legislation generally concern wild biodiversity conservation (through habitat protection) and crop genetic resources conservation but rarely address biodiversity for food and agriculture or wild biodiversity loss caused by food systems. The three regional reports conducted in the framework of this study reported a general lack of capacities and a particularly low level of involvement of farmers and other food producers in monitoring, data collection, and conservation activities. The combination of these two major observations leads us to the conclusion that the governance of BFA should be transformed to put food producers at the centre of biodiversity monitoring and conservation, in dialogue with scientists and institutional actors. Their specific expertise must be acknowledged and valued in the efforts of preserving the biodiversity that they cultivate and sustain. Beyond this needed shift in the governance of monitoring activities, we highlight the necessity of a regional articulation of monitoring efforts and a specific focus on local threatened varieties and breeds (beyond habitat conservation), while very comprehensively considering BFA and wild biodiversity impacted by food systems. Regarding biodiversity protection, we recommend – in addition to farmer-centered data collection and monitoring system implementation – addressing the root causes of biodiversity loss, adopting a systematic approach in legislations, policies, and actions while supporting agroecology, and fulfilling international instruments that guarantee the rights of producers to grow and raise local varieties and breeds.
