Book Description
Excerpt from Genetic Variation and Seed Transfer Guidelines for Ponderosa Pine in the Ochoco and Malheur National Forests of Central Oregon Adaptive genetic variation in seed and seedling traits was evaluated for 280 families from 220 locations. Factor scores from three principal components were related by multiple regression to latitude, longitude, elevation, slope, and aspect of the seed source, and by classification analysis to seed zone and elevation band in seed zone. Location variance was significant but not large. Multiple regression equations explained less than 50 percent of location variance. Slope-aspect variables were important. Keywords: Pinus ponderosa, seedlings, breeding zones, provenance, genetic variation, adaptive variation, genetic diversity.

Excerpt from Ten-Year Performance of Ponderosa Pine Provenances in the Great Plains of North America The variety arizonica [engelm.) Shaw - Pinus orizon ica according to some authorities - extends from south west New Mexico and southeastern Arizona southward along the Sierra Madre Occidental to near Durango, and along the Sierra Madre Oriental to near San Luis Potosi, Mexico. Although older studies of ponderosa pine - near Pikes Peak in Colorado and Priest River, Idaho (1911) - are considered to be the earliest examples of provenance tests of forest trees in North America (wang subsequent genetic research in ponderosa pine has concentrated mainly on the West Coast variety ponderosa.

Book Description
The 7-volume Encyclopedia of Biodiversity, Second Edition maintains the reputation of the highly regarded original, presenting the most current information available in this globally crucial area of research and study. It brings together the dimensions of biodiversity and examines both the services it provides and the measures to protect it. Major themes of the work include the evolution of biodiversity, systems for classifying and defining biodiversity, ecological patterns and theories of biodiversity, and an assessment of contemporary patterns and trends in biodiversity. The science of biodiversity has become the science of our future. It is an interdisciplinary field spanning areas of both physical and life sciences. Our awareness of the loss of biodiversity has brought a long overdue appreciation of the magnitude of this loss and a determination to develop the tools to protect our future. Second edition includes over 100 new articles and 226 updated articles covering this multidisciplinary field— from evolution to habits to economics, in 7 volumes The editors of this edition are all well respected, instantly recognizable academics operating at the top of their respective fields in biodiversity research; readers can be assured that they are reading material that has been meticulously checked and reviewed by experts Approximately 1,800 figures and 350 tables complement the text, and more than 3,000 glossary entries explain key terms
