This book was released on 1978 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tree damage occurring immediately after an outbreak of Douglas-fir tussock moth, Orgyia Pseudotsugata McD., and stand conditions 10 years later are described. Because of increased radial growth and ingrowth in the 10-year postoutbreak period, good evidence indicates that tree damage caused by the tussock moth may not be as severe in the overall stand dynamics as previously pictured. The insect probably plays a key role as a phytophagous regulator of primary production in some second-growth white fir stands in California and elsewhere.

Download or read book Trees and Wood in Dendrochronology written by Fritz H. Schweingruber and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 410 pages. Available in PDF, EPUB and Kindle. Book excerpt: The science of dendrochronology has grown significantly in the past 20 years. In the 1950s and 1960s, interest in the subject was limited to only a handful of scientists who perceived in dendrochronology a "l'art pour l'art". Today, however, specialists from many different fields recognize and are pursuing the problems of dendrochronology. Tree-ring research has acquired a permanent role in the various sciences of archeology, history, geology, ecology, and climatology. The founders of dendrochronology themselves were of varied scientific backgrounds and interests. For example, A. E. Douglass in the United States was an astronomer, B. Huber in Germany a forest-biologist, and F. N. Shvedov in Russia a climatologist. Today the spectrum is even broader. Many den drochronologists are authorities in mathematics, archeology, history, forestry, botany, wood technology, ecology geography, geology, etc. It is, therefore, understandable that it has become almost impossible for one individual to encompass the entire field. Bitvinskas (1974), Fritts (1976), Schweingruber (1983), and Mitsutani (1990) have attempted, each guided by his own interests, to provide at least an overview of the field. Recently, individual aspects have been presented by groups of authors in books edited by Fletscher (1978), Hughes et al. (1982), Jacoby and Hornbeck (1987) and Bradley and Jones (1992). It is very likely that in the future summaries covering each branch of dendrochronology will be published.
