Book Description
This volume comprises the proceedings of the Second International Rangelands Congress held in Adelaide, Australia in May 1984, and includes some 350 contributions drawn from 43 different countries. The Congress addressed the problem of the conflict between land-users and the degradation of this valuable resource. Some 40% of the Earth's land surface is and or alpine and therefore unsuitable for agricultural cultivation. Collectively, these lands are known as rangelands and in their natural state they constitute a habitat for grazing animals, both domestic and wild. Despite their low productivity, rangelands have been used for thousands of years as a source of food and fibre, but other uses such as mining, tourism, recreation and conservation are exerting increasing demands. The result is often conflict between land-users and degradation of the resource.

Book Description
In eastern Australia, grassy eucalypt woodlands have been under severe pressure from agricultural development, with problems of land degradation and species decline being most severe in the cropping lands of south-eastern Australia. Managing and Conserving Grassy Woodlands describes a set of principles that will enable landholders to maintain or increase productivity without compromising ecological sustainability, and at the same time maintaining a substantial proportion of the native flora and fauna. The book provides the technical foundations underpinning the principles and explains the importance of planning at a landscape scale. Each major principle is addressed in a separate chapter which explains the scientific understanding behind the principle and which discusses some of the issues relating to its practical application. Additional chapters outline the basic ecological concepts underpinning the principles and the responses of landholders who have had the opportunity to discuss and reflect on the principles. For those interested in translating the principles into a property plan, a final chapter explores the steps that can be taken. Managing and Conserving Grassy Woodlands is intended for those at the interface of disciplinary research and on-ground application, whether they are working in research, regional planning, extension, landcare or land management.

Book Description
Northern Australia: The Arenas of Life and Ecosystems on Half a Continent provides a geographical study of the interplay of environmental challenge and human endeavor in the vast arena of Northern Australia. This book is organized into three parts. Part A presents the contextual setting for Parts B and C. It includes a historical geographer's perspective on the ecological impact of 200 years of European settlement; a description of the use of satellite imagery; and discussion of some of the interactions among natural subsystems as they impinge on human activities (especially in the extensive rangelands). Part B discusses some of the human ecosystems which extend over a very large geographical territory. In these ecosystems the human population is small in terms of absolute number and relative to the population of other living things. These include the tropical marine ecosystems and their growing utilization for mariculture; and rangeland ecosytems dominated by cattle and the overlapping semi-arid grasslands. Part C discusses intensive ecosystems, where the human population is dominant in number.

Book Description
Now back in print. Plants of Western New South Wales grew from the long experience and expertise which the authors acquired during their employment with their respective organisations in the arid and semi-arid pastoral areas of the State. Each author became aware of the need for a comprehensive record illustrating and describing the great array of plants in the area. The need was identified both for people involved in research and advisory services, and particularly for the landholders who need to manage the plants for their livelihood. The book is a landmark because it draws together all of the existing knowledge of plants from the area, adds to it the extensive collections and research of the authors and presents the whole as a comprehensive collation and description of the plants of the dry pastoral portion of the State. Because of its comprehensive nature, the work is significant to pastoralists and people concerned with plants throughout Australia. The 1992 edition of Plants of Western New South Wales has been reprinted and published by CSIRO PUBLISHING with a one page appendix giving website addresses of various herbaria in Australia where the reader can readily access up-to-date information on botanical name changes.

Book Description
Biochemical Actions of Hormones, Volume XI is a 12-chapter text that covers the general and specific biochemical aspects of polypeptide and steroid hormones. The introductory chapters deal with the biochemical actions of the leukotrienes, the cyclic adenosine monophosphate, and the gonadotropin releasing hormone. The next chapters highlight detailed contributions on polypeptide hormone research. These chapters specifically tackle the insulin actions and the role of insulin in mammary gland development. The last series of chapters on steroid hormones includes X-ray crystallographic analysis of steroid structures and the significance of these studies on steroid-receptor interactions. These chapters also explore the analysis of the estrogen receptor with monoclonal antibodies; the role of estrogen receptor in responsive mammalian cells; the use of peroxidase as a marker of catechol estrogen action; and the activation and stabilization of the glucocorticoid receptor. This volume will be of great benefit to biochemists, biologists, endocrinologists, and researchers who are interested in the hormonal action and regulation.

Book Description
This book, first published in 1989, examines the controversial position of commercial utilisation in relation to wildlife conservation. Production of large mammals has earned respectability as an agricultural strategy and its evaluation has been listed as a priority requirement in the World Conservation Strategy. However, many authorities question whether wildlife production is a viable economic and environmental strategy, and suggest that it runs counter to its claimed purpose. This book evaluates this controversy by chronicling the changing role of wildlife and by reflecting on the implications of these trends. The book should be of interest to people both applauding and deploring the use of wildlife in this economic role.

Book Description
This book is open access under a CC BY-NC 2.5 license. This book provides an unprecedented synthesis of the current status of scientific and management knowledge regarding global rangelands and the major challenges that confront them. It has been organized around three major themes. The first summarizes the conceptual advances that have occurred in the rangeland profession. The second addresses the implications of these conceptual advances to management and policy. The third assesses several major challenges confronting global rangelands in the 21st century. This book will compliment applied range management textbooks by describing the conceptual foundation on which the rangeland profession is based. It has been written to be accessible to a broad audience, including ecosystem managers, educators, students and policy makers. The content is founded on the collective experience, knowledge and commitment of 80 authors who have worked in rangelands throughout the world. Their collective contributions indicate that a more comprehensive framework is necessary to address the complex challenges confronting global rangelands. Rangelands represent adaptive social-ecological systems, in which societal values, organizations and capacities are of equal importance to, and interact with, those of ecological processes. A more comprehensive framework for rangeland systems may enable management agencies, and educational, research and policy making organizations to more effectively assess complex problems and develop appropriate solutions.

Book Description
Australian High Country Raptors covers raptor species that regularly breed in the high country above 600 metres, from Goulburn in New South Wales down to the hills outside Melbourne, Victoria. Author Jerry Olsen explores the nature of these striking animals that are classified as Accipitriformes (diurnal hawks, falcons, kites and eagles), Falconiformes and Strigiformes (nocturnal owls). Comparisons between these high country raptors and lower-elevation breeders are also provided, in addition to comparisons with raptors found overseas, especially from North America and Europe. The book begins with a description of habitats and vegetation types in the high country, and which raptors are likely to be seen in each habitat type. It continues with sections on finding and watching raptors, raptor identification, hunting styles, food, breeding and behaviour, and conservation. Appendices provide species accounts for diurnal breeding species in the high country, with basic information about their ecology, distribution and conservation, as well as detailed instructions about handling an injured or orphaned raptor. Illustrated throughout with photographs and drawings, Australian High Country Raptors offers readers a chance to look into the lives of Australia’s fascinating birds of prey.
