Book Description
Conservation Biology for All provides cutting-edge but basic conservation science to a global readership. A series of authoritative chapters have been written by the top names in conservation biology with the principal aim of disseminating cutting-edge conservation knowledge as widely as possible. Important topics such as balancing conversion and human needs, climate change, conservation planning, designing and analyzing conservation research, ecosystem services, endangered species management, extinctions, fire, habitat loss, and invasive species are covered. Numerous textboxes describing additional relevant material or case studies are also included. The global biodiversity crisis is now unstoppable; what can be saved in the developing world will require an educated constituency in both the developing and developed world. Habitat loss is particularly acute in developing countries, which is of special concern because it tends to be these locations where the greatest species diversity and richest centres of endemism are to be found. Sadly, developing world conservation scientists have found it difficult to access an authoritative textbook, which is particularly ironic since it is these countries where the potential benefits of knowledge application are greatest. There is now an urgent need to educate the next generation of scientists in developing countries, so that they are in a better position to protect their natural resources.

Book Description
Cinnamon is the common name for the spice obtained from the dried inner bark of several species of the genus Cinnamomum in the Lauraceae family. In world trade, Cinnamomum cassia (L.) J. Presl Cinnamomum burmannii dominate, but it is of a different quality to ‘true’ or ‘Ceylon’ cinnamon produced from Cinnamomum zeylanicum Blume (C. verum J. Presl), with the latter much easier to process, giving a more delicate, sweeter flavor with nuances of clove, but more importantly with only traces (often below detection thresholds) of coumarin, compared with 5–7 g/kg in other species. Cinnamon has been a popular and expensive spice in many civilizations, including ancient Egypt, Rome and in 14th and 15th century Europe, where it was used primarily to preserve meat for its antibacterial properties, fine aroma and flavor. Ancient Egyptians used cinnamon in mummification process due to its antibacterial properties and fragrance. The quest for cinnamon brought many explorers to Ceylon, whose ancient history is intertwined with the cinnamon trade. Ancient Egyptians and Romans used cinnamon as a valued spice and as an incense. In recent years, much research has been conducted in crop improvement, processing and value addition in cinnamon. In addition to direct use as a condiment/spice, cinnamon has found a multitude of uses in the food and beverage, traditional medicine, pharmacology, nutraceutical and cosmetics industries. Ceylon cinnamon is unique in that oils distilled from the bark (major constituents are cinnamaldehyde and oleoresins), leaf (eugenol is the major constituent used in dentistry, perfumes, flavorings and as an antioxidant) and roots (camphor) have different industrial uses. Cinnamaldehyde is now a proven natural bactericide widely used in food and beverage industry, effective against Salmonella spp. and Escherichia coli. Thus, it has become an important natural component of organic fruit and vegetable juices to enhance microbial safety of these nutritious beverages. Because of its manifold uses, cinnamon is an important crop. There have been many recent publications on its ethnobotany, genetics, crop improvement, agronomy, processing, biotechnology, chemistry, food and medicinal uses, and industrial applications. However, one book condensing all these findings is lacking. Our publication, with chapters devoted to all these aspects of cinnamon written by experts in these fields, condenses current knowledge into a single source and contribute to the advancement and dissemination of knowledge and technology. Contributors to the book constitute internationally renowned senior scientists and academics with hands-on experience as well as movers and shakers of industry, thereby striking a right balance between theory and practice. Therefore it is a valuable source for students, teachers, scientists, planners policy makers, practicing agriculturists and industrialists, and a prized acquisition to any library in higher education institutions, R & D institutions and public and private sector institutions in agriculture and allied fields.

Book Description
This book describes the scientific principles that are used throughout the world to ensure the rapid, healthy growth of forest plantations. As the population of the world increases so does the amount of wood people use. Large areas of natural forests are being cleared every year and converted to other uses. Almost as large an area of plantation forests is being established annually to replace those lost natural forests. Eventually, plantations will produce a large proportion of the wood used around the world for firewood, building, the manufacture of paper and bioenergy. Forest plantations can also provide various environmental benefits including carbon storage, rehabilitation of degraded land, serving as disposal sites for various forms of industrial or agricultural waste and enhancing biodiversity in regions that have been largely cleared for agriculture. Whatever their motivation, plantation forest growers want their plantations to be healthy and grow rapidly to achieve their purpose as soon as possible. This book discusses how this is done. It is written for a worldwide audience, from forestry professionals and scientists through to small plantation growers, and describes how plantations may be grown responsibly and profitably.

Book Description
The definitive resource for finding, identifying, and conserving Maryland’s amphibians and reptiles. Naturalists, herpetologists, and ecologists alike agree that tracking herpetofauna is a challenging undertaking. Scientists are concerned about the decline of once-familiar species, but evidence has often been too anecdotal to support firm conclusions. To better understand the distribution of amphibians and reptiles in Maryland and forecast species' futures in a time of accelerated environmental threats, conducting a comprehensive statewide survey updating 1970s-era distribution maps seemed ideal. However, this endeavor was of an impossibly ambitious scope for scientists alone to tackle. Enter the Maryland Amphibian and Reptile Atlas project, comprising nearly a thousand dedicated citizen scientists who discovered and recorded the locations of herpetofauna throughout every corner of Maryland. In The Maryland Amphibian and Reptile Atlas, Heather R. Cunningham and Nathan H. Nazdrowicz present the findings of this massive undertaking. This definitive guide combines nearly 160 comprehensive new herpetological maps with historical distribution maps and in-depth species accounts. Color photos illustrate the natural history of the 89 species of frogs, salamanders, turtles, snakes, and lizards that call the state home. Essays discuss historical studies, the effects of Maryland's current climate, geology, and habitat diversity—and the myriad conservation issues these animals face. This richly detailed book represents a triumph of citizen science and the culmination of an intensive research partnership. It will appeal to both amateurs and professionals interested in herpetology, natural history, or ecology, as well as those with a special interest in Maryland's biodiversity.

Book Description
This project was developed to identify a set of risk indicators to predict the risk of summer-ground loss at the watershed level within the Vanderhoof Forest District (VFD) and others, subsequent to the mountain pine beetle (MPB) infestation of lodgepole pine stands. This report was done in relation to the VFD annual cut of stands, and the following difficultings that operators found in running their equipment in wet versus dry soils in harvest years. Risk indicators were selected from available GIS information, aerial photographs, and local knowledge. The most effective indicators for predicting the risk of wet-ground areas at the watershed level were found to be lodgepole pine content, understorey, drainage density, sensitive soils, and the topographic index, all of whose values are available from provincial databases. The work includes information on materials and methods, results and discussion, the authors' conclusions, as well as recommendations.--Includes text from document.

Book Description
The last fifteen years have been a period of dramatic change, both in the world at large and within the fields of ecology and conservation. The end of the Cold War, the dot-com boom and bust, the globalizing economy, and the attacks of September 11, among other events and trends, have reshaped our worldview and the political environment in which we find ourselves. At the same time, emerging knowledge, needs, and opportunities have led to a rapid evolution in our understanding of the scientific foundations and social context of conservation. Correction Lines is a new collection of essays from one of our most thoughtful and eloquent writers on conservation, putting these recent changes into perspective and exploring the questions they raise about the past, present, and future of the conservation movement. The essays explore interrelated themes: the relationship between biological and social dimensions; the historic tension between utilitarian and preservationist approaches; the integration of varied cultural perspectives; the enduring legacy of Aldo Leopold; the contrasts and continuities between conservation and environmentalism; the importance of political reform; and the need to "retool" conservation to address twentyfirst-century realities. Collectively the essays assert that we have reached a critical juncture in conservation—a "correction line" of sorts. Correction Lines argues that we need a more coherent and comprehensive account of the past if we are to understand our present circumstances and move forward under unprecedented conditions. Meine brings together a deep sense of history with powerful language and compelling imagery, yielding new insights into the origins and development of contemporary conservation. Correction Lines will help us think more clearly about the forces that have changed, and are changing, conservation, and inspire us to address current realities and future needs.
