Book Description
Poplars and willows form an important component of forestry and agricultural systems, providing a wide range of wood and non-wood products. This book synthesizes research on poplars and willows, providing a practical worldwide overview and guide to their basic characteristics, cultivation and use, issues, problems and trends. Prominence is given to environmental benefits and the importance of poplar and willow cultivation in meeting the needs of people and communities, sustainable livelihoods, land use and development.

Book Description
Highlighting the importance to ecological studies of incorporating humans and their effects on ecosystems, leading experts from a variety of disciplines address a number of important issues, including: * the prominent role of humans in the function of ecosystems on Earth * why humans have been ignored in ecological studies * approaches taken by social scientists, historians, geographers, economists, and anthropologists in the study of human activities * the emergence of a new ecological paradigm accommodating human activities * methods for studying subtle human effects, and human- populated ecosystems * future research and training required to include humans effectively as components of ecological systems. Of interest to students and researchers in ecology, and to policy-makers and environmental managers. In addition, it makes social scientists aware of new opportunties for integrating their ideas with those of ecologists.

Abstract: Average dry weight and nutrient levels in current foliage from red spruce and balsam fir seedlings and saplings in the understory of a 25-year old aspen and birch stand were observed 3 years after N, P, and lime treatments were applied. Elemental concentrations were plotted as a function of needle weight and quantity of element per needle. This allows interpretation of treatment effect on overall nutrient levels for both concentration and quantity of each element in the foliage. In balsam fir, dry weight per needle was significantly increased by N fertilizer. Nitrogen also significantly affected levels of ash, N, P, K, Ca, Fe, Mn, Zn, and Na in balsam fir foliage. In red spruce, dry weight per needle, N, and Fe levels all responded to N fertilizer; P fertilizer affected P foliar concentration and lime significantly affected Mn levels. In both species there were significant interactions among the N, P, and lime treatments, indicating that response to one element varied according to the other elements added simultaneously. Balsam fir needles were heavier and contained higher levels of nutrients than red spruce needles. The magnitude of changes in elemental levels was generally greater for balsam fir than for red spruce.
