There is currently no basic text in wildlife law suitable for the wide range of courses in wildlife conservation and animal welfare at both bachelors and masters level, or for the large number of people who work in conservation and animal welfare; The Laws Protecting Animals and Ecosystems fills the gap in this significant market for a basic law text applicable to students and professionals whose primary training is in biology but who require a basic understanding of the laws relating to the protection of animals and ecosystems. The text is applicable to a wide range of subjects, including wildlife conservation, animal handling, animal welfare, animal husbandry, and veterinary science. This foundational text supports those studying animal and ecosystem law by providing an overview of the basic legal principles, national and international laws, terminology, the legal mechanisms used to protect animals and ecosystems, and a compendium of the major animal welfare and conservation laws in major English speaking countries. Dr. Rees has been teaching wildlife law for 20 years and ecology for over 35 years and is ideally placed to write this book.

Feral and stray domestic cats occupy many different habitats. They can resist dehydration for months by relying exclusively on the tissue water of their prey allowing them to colonize remote deserts and other inhospitable places. They thrive and reproduce in humid equatorial rainforests and windswept subantarctic islands. In many areas of the world feral cats have driven some species of birds and mammals to extinction and others to the edge, becoming a huge conservation concern. With the control of feral and stray cats now a top conservation priority, biologists are intensifying efforts to understand cat behaviour, reproductive biology, use of space, intraspecies interaction, dietary requirements, prey preferences, and vulnerability to different management strategies. This book provides the most comprehensive review yet published on the behavior, ecology and management of free-ranging domestic cats, whether they be owned, stray, or feral. It reviews management methods and their progress, and questions several widely accepted views of free-ranging cats, notably that they live within dominance hierarchies and are highly social. Insightful and objective, this book includes: a functional approach, emphasizing sensory biology, reproductive physiology, nutrition, and space partitioning; clear treatment of how free-ranging cats should be managed; extensive critical interpretation of the world’s existing literature; results of studies of cats in laboratories under controlled conditions, with data that can also be applied to pet cats. Free-ranging Cats: Behavior, Ecology, Management is valuable to ecologists, conservation scientists, animal behaviorists, wildlife nutritionists, wildlife biologists, research and wildlife veterinarians, clinical veterinarians, mammalogists, and park and game reserve planners and administrators.

Gravel-Bed Rivers: Processes, Tools, Environments presents a definitive review of current knowledge of gravel-bed rivers, derived from the 7th International Gravel-bed Rivers Workshop, the 5-yearly meeting of the world’s leading authorities in the field. Each chapter in the book has been specifically commissioned to represent areas in which recent progress has been made in the field. The topics covered also represent a coherent progression through the principal areas of the subject (hydraulics; sediment transport; river morphology; tools and methods; applications of science). Definitive review of the current knowledge of gravel-bed rivers Coverage of both fundamental and applied topics Edited by leading academics with contributions from key researchers Thoroughly edited for quality and consistency to provide coherent and logical progression through the principal areas of the subject.

The Banggai cardinalfish, Pterapogon kauderni, is a fascinating species that possesses a series of remarkable biological characteristics making it unique among coral reef fishes. It has been the focus of studies in reproduction, ecology, population genetics and evolution. In addition, since its rediscovery in the late 1990s, it has become tremendously popular in the international ornamental fish trade, and indiscriminate collecting has led to its inclusion in the 2007 IUCN Red List as an endangered species. This book is divided into three main parts: a general introduction to the fish, including a historical synopsis with an overview of the Banggai Archipelago; a comprehensive treatment of the species’ natural history (distribution, morphology, reproduction, embryology, ecology, genetics, systematics and evolution); an account of the conservation of the species, including descriptions of its fishery, attempts to protect it under CITES, and introduction programmes. The book also includes an appendix offering information on captive breeding, juvenile mortality reduction, and common diseases. This book is a unique resource for ichthyology students and researchers working on fish biology, ecology and conservation, and for marine ornamental fish hobbyists and aquarium professionals.

This book is intended for those with an academic, scientific and practical interest in river conservation and management. It provides an overview of how changes in legislation, policies, institutional responsibilities, science, technology, practical techniques and public perception have influenced how rivers have been managed over the past 20 years and the challenges that lie ahead during the next 20 years. The book is based on the international conference River Conservation and Management:20 Years On held at York. Thirty-one chapters, with contributions from North and South America, Europe, Asia and Australasia provide a wide-ranging perspective on this complex but profoundly important subject. Following an introduction that chronicles the most important contextual changes, the book is organized into four broad topics: Catchment management, ecosystem integrity and the threats to river ecosystems – this covers progress on understanding and addressing the pressures affecting rivers, many of which will be amplified by climate change and increasing human demands for water; Methods and approaches – illustrating some recent techniques that have been developed to assess condition and conservation status across different types of river; Recovery and rehabilitation – providing an insight into the principles, practice, public involvement and institutional networks that support and make improvements to modified river reaches; Integrating nature conservation into wider river management –demonstrating the importance of integrated planning, involvement of local communities and the use of adaptive management in achieving multiple environmental and economic benefits along rivers used for different purposes. The final chapter discusses the challenges faced in dealing with an uncertain future. More than 1200 different references and numerous web-site citations provide the reader with an invaluable source of knowledge on the subject area.

This new edition of Biological Oceanography has been greatly updated and expanded since its initial publication in 2004. It presents current understanding of ocean ecology emphasizing the character of marine organisms from viruses to fish and worms, together with their significance to their habitats and to each other. The book initially emphasizes pelagic organisms and processes, but benthos, hydrothermal vents, climate-change effects, and fisheries all receive attention. The chapter on oceanic biomes has been greatly expanded and a new chapter reviewing approaches to pelagic food webs has been added. Throughout, the book has been revised to account for recent advances in this rapidly changing field. The increased importance of molecular genetic data across the field is evident in most of the chapters. As with the previous edition, the book is primarily written for senior undergraduate and graduate students of ocean ecology and professional marine ecologists.
