Book Description
Breeding Pest-Resistant Trees documents the proceedings of a N.A.T.O. and N.S.F. Advanced Study Institute on Genetic Improvement For Disease and Insect Resistance of Forest Trees held in Pennsylvania State University from August 30 to September 11, 1964. This book compiles the study and research of geneticists, pathologists, entomologists, and foresters concerned with the genetic resistance of forest trees to pests and breeding programs for disease- and insect-resistant trees. This compilation is divided into three parts. The first part discusses about the résumés of research related to forest tree pest resistance by geographic regions. Part II focuses on the reports of significant research advances in the basic knowledge of disease and insect resistance of forest trees, while Part III includes the discussion of approaches and methods for genetic improvement in pest resistance of forest trees. The topics covered include the variation and inheritance of pest resistance in forest trees; environmental effects on the host-pest relationship; review of basic knowledge of forest tree pest resistance; selection for pest resistance in wild populations; and testing and evaluating inherent pest resistance. This publication is a good source for students and individuals conducting work on the resistance of forest trees to diseases and pest insects.

Book Description
Whitebark pine is a dominant feature of western high-mountain regions, offering an important source of food and high-quality habitat for species ranging from Clark's nutcracker to the grizzly bear. But in the northwestern United States and southwestern Canada, much of the whitebark pine is disappearing. Why is a high-mountain species found in places rarely disturbed by humans in trouble? And what can be done about it.Whitebark Pine Communities addresses those questions, explaining how a combination of altered fire regimes and fungal infestation is leading to a rapid decline of this once abundant -- and ecologically vital -- species. Leading experts in the field explain what is known about whitebark pine communities and their ecological value, examine its precarious situation, and present the state of knowledge concerning restoration alternatives. The book. presents an overview of the ecology and status of whitebark pine communities offers a basic understanding of whitebark pine taxonomy, distribution, and ecology, including environmental tolerances, community disturbance processes, regeneration processes, species interactions, and genetic population structure identifies the threats to whitebark pine communities explains the need for management intervention surveys the extent of impact and losses to dateMore importantly, the book clearly shows that the knowledge and management tools are available to restore whitebark pine communities both locally and on a significant scale regionally, and it provides specific information about what actions can and must be taken.Whitebark Pine Communities offers a detailed portrait of the ecology of whitebark pine communities and the current threats to them. It brings together leading experts to provide in-depth information on research needs, management approaches, and restoration activities, and will be essential reading for ecologists, land managers, and anyone concerned with the health of forest ecosystems in the western United States.
