Book Description
This collection of poems from Vermont farmer Ross Thurber is divided into four sections: "Green Popplewood," "Sunburnt Juniper," "Stag Horn Sumac," and "Snow Melt, Black Brook." Each section represents a seasonal form of succession that is both literal and abstract. Ultimately the poems in this manuscript have been winnowed to represent a narrative that echoes the idea that, like a lyric poem, stability is only a moment in time--one to be cherished.

Book Description
The Sustainable Forestry Handbook is widely considered to be the essential aid to understanding and implementing sustainable forest management. Providing a clear and concise guide to the practicalities of implementing international standards for sustainable forest management, this fully updated second edition covers new Forest Stewardship Council requirements, High Conservation Value Forests, clearer requirements on pesticides and developments in policy and forest governance. Aimed at forest managers, and employing extensive cross referencing and easy-to-understand illustrations, this highly practical handbook explains in clear terms what the standards require forest managers to do and how they might go about implementing them.

Book Description
Seeds: Ecology, Biogeography, and Evolution of Dormancy and Germination provides a working hypothesis of the ecological and environmental conditions under which carious kinds of seed dormancy have developed. It also presents the seed germination of morethan 3500 species of trees, shrubs, vines, and herbaceous species.

Book Description
This book presents a new economic theory developed from physical and biological principles. It explains how technology, social systems and economic values are intimately related to resources. Many people have recognized that mainstream (neoclassical) economic theories are not consistent with physical laws and often not consistent with empirical patterns, but most feel that economic activities are too complex to be described by a simple and coherent mathematical theory. While social systems are indeed complex, all life systems, including social systems, satisfy two principles. First, all systems need to extract resources from the external environment to compensate for their consumption. Second, for a system to be viable, the amount of resource extraction has to be no less than the level of consumption. From these two principles, we derive a quantitative theory of major factors in economic activities, such as fixed cost, variable cost, discount rate, uncertainty and duration. The mathematical theory enables us to systematically measure the effectiveness of different policies and institutional structures at varying levels of resource abundance and cost.The theory presented in this book shows that there do not exist universally optimal policies or institutional structures. Instead, the impacts of different policies or social structures have to be measured within the context of existing levels of resource abundance. As the physical costs of extracting resources rise steadily, many policy assumptions adopted in mainstream economic theories, and workable in times of cheap and abundant energy supplies and other resources, need to be reconsidered. In this rapidly changing world, the theory presented here provides a solid foundation for examining the long-term impacts of today's policy decisions.

Book Description
Now expanded and in full colour throughout, ORAL MICROBIOLOGY retains its unique ecological approach to the subject which helps the reader determine whether an organism will have a pathogenic or commensal relationship at a given site. In the new edition, greater emphasis is placed on the role of current molecular biology techniques in the understanding of oral microbes. The book also provides insight into current therapeutic and prophylactic antibiotic use, infection control, and the relationships between oral and general health. New authorship also offers additional expertise on viral and fungal pathogens and the role of oral microbes in acute and chronic infections. - Successfully describes the complex relationship between the resident oral microflora and the host in health and disease - Retains a unique ecological approach to the subject which benefits the reader by providing a clear set of principles to explain the underlying issues that determine whether the microflora will have a beneficial or an adverse relationship with the host at a particular site - Published for the first time in full colour, Oral Microbiology has been expanded and completely rewritten with almost 100 brand new illustrations - Includes discussion of the latest molecular biology techniques which have revolutionized our knowledge of oral microbes - Highlights the biological and clinical significance of the existence of the oral microflora in the form of a biofilm on dental and mucosal surfaces - Includes contemporary views on therapeutic and prophylactic antibiotic use, infection control, and the relationships between oral and general health - New authorship offers further expertise on viral and fungal pathogens and the role of oral microbes in acute and chronic infections
