From speech to breathing to overt movement contractions of muscles are the only way other than sweating whereby we literally make a mark on the world. Locomotion is an essential part of this equation and exciting new developments are shedding light on the mechanisms underlying how this important behavior occurs. The Neural Control of Movement discusses these developments across a variety of species including man. The editors focus on highlighting the utility of different models from invertebrates to vertebrates. Each chapter discusses how new approaches in neuroscience are being used to dissect and control neural networks. An area of emphasis is on vertebrate motor networks and particularly the spinal cord. The spinal cord is unique because it has seen the use of genetic tools allowing the dissection of networks for over ten years. This book provides practical details on model systems, approaches, and analysis approaches related to movement control. This book is written for neuroscientists interested in movement control.

This book, first published in 1985, provides a comprehensive treatment of the role of the military within civil society. With analysis from a policing and military viewpoint (both rarely available in public), and legal and historical perspectives, this book sheds valuable light both on the role of the law in democratic societies, and on the way the balance between the state and civil liberties has been struck.

How wildfires affect animal and plant populations is a complex ecological issue. Robert Whelan examines fire as an ecological agent and discusses how populations of organisms are affected by its passage. Drawing examples from several continents, the author studies the impact of fires on individual organisms, populations, and communities. He looks at the effects on ecological processes such as predator-prey, and plant-herbivore interactions, and summarizes the major aspects of ecology that are of particular importance to fire control--both protection against wildfires and fire as a management tool. This book is unique in its emphasis on general ecological principles rather than regional treatment, and it will be of interest to ecologists, foresters, and other land managers.

As the human impact on the earth leads to ever increasing environmental degradation, the restoration of dwindling populations of numerous plant and animal species is becoming ever more important. In this unique volume, the political, biological and experimental procedures affecting the restoration of populations of both plants and animals are examined using case studies to illustrate basic points. Conceptual issues concerning the organization and management of restoration efforts and plans for the restoration of a wide variety of species including the Pitcher's thistle and woodland caribou are outlined. The success and progress of implemented plans for other species such as the Lakeside daisy and black-footed ferret are then evaluated, and the book ends with a broad overview, suggesting future opportunities and problems. The book will interest especially students and practitioners of restoration ecology.

For over one hundred years, ornithologists and amateur birders have jointly campaigned for the conservation of bird species, documenting not only birds' beauty and extraordinary diversity, but also their importance to ecosystems worldwide. But while these avian enthusiasts have noted that birds eat fruit, carrion, and pests; spread seed and fertilizer; and pollinate plants, among other services, they have rarely asked what birds are worth in economic terms. In Why Birds Matter, an international collection of ornithologists, botanists, ecologists, conservation biologists, and environmental economists seeks to quantify avian ecosystem services the myriad benefits that birds provide to humans. The first book to approach ecosystem services from an ornithological perspective, Why Birds Matter asks what economic value we can ascribe to those services, if any, and how this value should inform conservation. Chapters explore the role of birds in such important ecological dynamics as scavenging, nutrient cycling, food-chains, and plant-animal interactions all seen through the lens of human well-being to show that quantifying avian ecosystem services is crucial when formulating contemporary conservation strategies. Both elucidating challenges and providing examples of specific ecosystem valuations and guidance for calculation, the contributors propose that in order to advance avian conservation, we need to appeal not only to hearts and minds, but also to wallets.

As the human impact on the earth leads to ever increasing environmental degradation, the restoration of dwindling populations of numerous plant and animal species has become urgent. In this volume, contributors examine the conceptual, planning, and applied aspects of recovery of rare or endangered species. It is unique in its treatment of both plants and animals, and in its presentation of scientific approaches to implemented restorations. Experts report on the restoration efforts and plans for the restoration of a wide variety of species including the dune thistle, lakeside daisy, woodland caribou, kit fox, and black-footed ferret and end with a broad overview, suggesting future opportunities and problems.
