Grasslands are everywhere: agricultural land, playing fields and road verges; but while species-poor, intensively managed grasslands are widespread, colourful semi-natural grasslands and heathlands, buzzing with life, are scarce. These semi-natural habitats are ancient, cultural landscapes, which are of considerable, if not international importance for biodiversity. However, despite targets for the conservation and restoration of these valuable grasslands and heathlands, these habitats continue to decline before our eyes. Lowland Grassland and Heathland Habitats contrasts the uniformity of intensively managed grassland with the diversity of traditionally managed grasslands and heathlands. It examines topics of concern to the ecologist or habitat manager such as causes of the loss and deterioration of these habitats, including inappropriate management, eutrophication and climate change. It then evaluates opportunities for positive change, such as conservation, restoration and creation. A series of case-studies illustrates the pressures on some lowland grassland and heathland habitat types and looks at ways to enhance them for biodiversity. This habitat guide features illustrated species boxes of typical plants and animals, as well as a full species list, a series of projects on the ecology of grassland and heathland species, a colour plate section, up-to-date references and information, and a full glossary. It will provide students and environmentalists with a deeper understanding of the nature and importance of lowland grasslands and heathlands.
Biodiversity is recognised to be of global importance, yet species and habitats continue to be under increasing pressure from human-induced influences. Environmental concerns are high on the political agenda, driving increased legislation to protect the natural environment. The starting point for much of this legislation is the requirement for a comprehensive biodiversity audit. For those needing to undertake such audits, this Handbook, first published in 2005, provides standard procedures which will enable practitioners to better monitor the condition of the biodiversity resource, resulting in improved data upon which to base future policy decisions and actions. Organised in three parts, the Handbook first addresses planning, covering method selection, experimental design, sampling strategy, and data analysis and evaluation. The second part describes survey, evaluation and monitoring methods for a broad range of habitats. Part three considers species and provides information on general methods before addressing specific methods of survey and monitoring for the major taxonomic groups.
Coastal Conservation and Management provides the reader with a synthesis of the range and variation of the main coastal formations and includes practical guidance on their management. The book discusses all the main coastal habitats of importance for nature conservation (saltmarsh, shingle, sand dune and seacliff) as well as combinations of these habitats (estuaries and other coastal wetlands). It offers a comprehensive picture of both the soft sedimentary formations and those which are more resilient. While these habitats have all been covered elsewhere in the literature, no single volume gives such a wide-ranging account. An attempt is made throughout to provide the reader with a basic understanding of the importance and range of variation of each habitat and coastal ecosystem. The principal issues are discussed and the key management options identified. Some prescriptive suggestions are made, though for the most part, the reader is left to ponder the issues and their possible solutions.
This edition of Thermodynamics is a thoroughly revised, streamlined, and cor rected version of the book of the same title, first published in 1975. It is intended for students, practicing engineers, and specialists in materials sciences, metallur gical engineering, chemical engineering, chemistry, electrochemistry, and related fields. The present edition contains many additional numerical examples and prob lems. Greater emphasis is put on the application of thermodynamics to chemical, materials, and metallurgical problems. The SI system has been used through out the textbook. In addition, a floppy disk for chemical equilibrium calculations is enclosed inside the back cover. It contains the data for the elements, oxides, halides, sulfides, and other inorganic compounds. The subject material presented in chapters III to XIV formed the basis of a thermodynamics course offered by one of the authors (R.G. Reddy) for the last 14 years at the University of Nevada, Reno. The subject matter in this book is based on a minimum number of laws, axioms, and postulates. This procedure avoids unnecessary repetitions, often encountered in books based on historical sequence of development in thermodynamics. For example, the Clapeyron equation, the van't Hoff equation, and the Nernst distribution law all refer to the Gibbs energy changes of relevant processes, and they need not be presented as radically different relationships.
