Download or read book Dwarf Mistletoe in Red and White Firs in California--23 to 28 Years After Inoculation written by J. R. Parmeter and published by . This book was released on 1989 with total page 6 pages. Available in PDF, EPUB and Kindle. Book excerpt: Spread and buildup of dwarf mistletoe, Arceuthobiun abietinum, was studied on inoculated white fir, Abies concolor, and red fir, A. magnifica, in northern Califomia for 23 to 28 years. At the end of these studies (1986), and in the absence of overstory infection, 13 of 23 trees had dwarf mistletoe populations that were the same or smaller than the original populations resulting from inoculation. Mortality of infections was the main factor limiting population increases. Live crown ratio of all trees averaged over 0.8. The average ratio of tree height growth to vertical spread rate of dwarf mistletoe was 11.5 to 1 in white fir and 7 to 1 in red fir in the Sierra Nevada. In the southem Cascades, the average ratio was 1.7 to 1 in red fir. About one fourth of the trees became infected in the bole. Of 14 additional trees infected by lateral spread of the parasite, 13 were within 6 m of the source of infection. Evidence continues to indicate that losses from dwarf mistletoes will be small in well-managed young fir stands free from infected overstory trees and properly spaced to promote good growth.

Book excerpt: The treetops of the world's forests are where discovery and opportunity abound, however they have been relatively inaccessible until recently. This book represents an authoritative synthesis of data, anecdotes, case studies, observations, and recommendations from researchers and educators who have risked life and limb in their advocacy of the High Frontier. With innovative rope techniques, cranes, walkways, dirigibles, and towers, they finally gained access to the rich biodiversity that lives far above the forest floor and the emerging science of canopy ecology. In this new edition of Forest Canopies, nearly 60 scientists and educators from around the world look at the biodiversity, ecology, evolution, and conservation of forest canopy ecosystems. Comprehensive literature list State-of-the-art results and data sets from current field work Foremost scientists in the field of canopy ecology Expanded collaboration of researchers and international projects User-friendly format with sidebars and case studies Keywords and outlines for each chapter

Available in PDF, EPUB and Kindle. Book excerpt: Every year we see a remarkable increase in scientific knowledge. We are learning more each day about the world around us, about the numerous biological organisms of the biosphere, about the physical and chemical processes that shaped and continue to change our planet. The cataloging, retrieval, dissemination, and use of this new information along with the continued development of new computer technology provide some of the most challenging problems in science as we enter the Information Age. With the explosion of knowledge in science, it is especially important that students in introductory courses learn not only the basic material of a subject, but also about the newest developments in that subject. With this goal in mind, we have prepared a second edition of Introduction to Plant Diseases: Identification and Management. We prepared this edition with the same general purpose that we had for the first edition - to provide practical, up-to-date information that helps in the successful management of diseases on food, fiber, and landscape plants for students who do not have a strong background in the biological sciences. We included new information on (1) the precise identification of diseases and the pathogens that cause them, (2) the development of epidemics of plant diseases, (3) the application of biotechnology in plant pathology, (4) the use of alternative methods of crop production and disease management that help protect the environment, and (5) diseases that have become more important since the first edition was published.
