Book Description
This comprehenisive text approaches the subject from an ecological/evolutionary biological perspective. The assumption is that one cannot study forest insects without understanding the dynamics of the relationship between an insect and its host plant. This relationship includes knowing what factors control forest insect populations such as food, food quality, tree vigor, host selection, and symbiotic relationships. The authors also discuss tree-injuring insects from the perspective of their influence on tree physiology and growth as well as economic and commercial effects. The book represents a "modern" approach to the topic of forest and shade tree insects; is well-illustrated; and includes a comprehensive primary reference list.

Book Description
Agroforestry research is central to developing methods for the sustainable use of natural renewable resources, evolving to address the needs of the coming century. It is now necessary to consolidate the scientific gains now being made in process-oriented research and to develop a policy framework to encourage the adoption of sustainable land use practices. Agroforestry plays an important role in conserving forest resources, reducing the need for deforestation. Further, if `forest' is broadly defined as tree cover, agroforestry will also increase the proportion of woody biomass in farming landscapes. The papers selected for inclusion in Agroforestry: Science, Policy, and Practice establish agroforestry as an interdisciplinary science focused on the practical imperative of assisting farmers, forest dwellers and landscape-level planners to achieve sustainable food, fuel and timber production into the 21st century.
