Tree-Ring Bulletin, Volume 38 (1978)

 

ABOUT THE COLLECTION

Tree-Ring Research is the peer-reviewed journal of the Tree-Ring Society. The journal was first published in 1934 under the title Tree-Ring Bulletin. In 2001, the title changed to Tree-Ring Research.

The Tree-Ring Society and the Laboratory of Tree-Ring Research at the University of Arizona partnered with the University Libraries to digitize back issues for improved searching capabilities and long-term preservation. New issues are added on an annual basis, with a rolling wall of five years.

  • Effects of Defoliation by Douglas-Fir Tussock Moth on Ring Sequences of Douglas-Fir and Grand Fir
    Brubaker, Linda B.; College of Forest Resources, University of Washington, Seattle, Washington (Tree-Ring Society, 1978)
    Increment cores were collected from 10 stands in mixed-conifer forest stands which had suffered varying levels of Douglas-fir tussock moth defoliation during 1946, 1964, and 1973 infestations in north central Idaho. Ring-width measurements, standardized to remove inherent growth trends, were compared between host (Douglas-fir and grand fir) and nonhost (western larch, ponderosa pine, western white pine) species for evidence of growth losses due to defoliation. Heavy defoliation caused growth of host species to decrease 75 %-90% in one year. Normal growth rates returned within 3-4 years after maximum defoliation, however. The effect of moderate defoliation could not be reliably identified in the data.

  • Dating the Geographical Migration of Quergus Petraea and Q. Robur in Holocene Times
    Fletcher, John; Research Laboratory for Archaeology and the History of Art, Oxford University (Tree-Ring Society, 1978)
    Huber identified in samples from the forests of central Europe features for characterising by their wood structure the two species of British oak. We have confirmed for recently felled oaks the suitability of his method of analysis and applied it to timbers from ancient buildings and to samples from sub-fossil oaks. The two species appear to have persisted in separate locations during the last ice age. Such analysis of the numerous Holocene oaks in Europe now being dated by den - drochronology offers the possibility of studying the separate migration of the species.

  • Dendroclimatology of Elm in London
    Brett, Donald W.; Botany Department, Bedford College, University of London (Tree-Ring Society, 1978)
    A pilot investigation of 11 trees from London parks has shown that elm (Ulmus) is suitable for dendrochronology and dendroclimatological analysis. Ten trees are shown to crossdate well and form the basis of a London group elm chronology for the years 1900-1971; chronologies derived from fewer trees cover the period 1840-1971. Correlations with monthly climatic variables and seasonal rainfall and soil moisture totals are described. Response functions for the relationship between the London elm chronology and precipitation and temperature recorded at Kew demonstrate the direct relationship between ring width and precipitation during the growing season and during the previous autumn and early winter (September to December), an inverse relationship to rainfall the previous summer; above average temperature during the previous autumn leads to above average ring width but there is an inverse relation between ring width and temperature during March and April at the commencement of the growing season.

  • The Dendroclimatological Value of the European Larch (Larix decidua Mill.) in the French Maritime Alps
    Serre, Françoise; Laboratoire de Botanique Historique et Palynologie, Faculté des Sciences et Techniques de Marseille St-Jérôme, Marseille, France (Tree-Ring Society, 1978)
    The relations between the width growth of thousand year old larches of the French Maritime Alps (Vallée des Merveilles, north of Nice) and climate are investigated in several ways. A first analysis of tree-ring width compared with meteorological data of the last 21 years (1954-1974) reveals above all an inverse relationship to precipitation and temperature for the months of June and July. Moreover the temperature and rain of the autumn (September in particular) and previous winter seem to affect ring formation as well as the temperature and rain of March and May of the current season. Thus comparison of tree-ring width variations - during the thousand year period of tree growth - with climatic data from various sources (history, chronicle, variations of the glacial front lines, known climatic episodes) shows that climate reconstruction, over several centuries, at the limits of the Mediterranean zone, can be obtained with larch of the French Maritime Alps.

  • Dendrochronology of Oak in North Wales
    Hughes, M. K.; Leggett, P.; Milsom, S. J.; Hibbert, F. A.; Biology Department, Liverpool Polytechnic, Liverpool, England (Tree-Ring Society, 1978)
    The tree-ring characteristics of material used in a 35-tree, 265-year modern oak chronology from a site in North Wales are discussed. Three methods of standardisation are compared and temporal variation in chronology statistics examined. A response function using rainfall data from a station very close to the tree site related 45% of the chronology variance to climate and 73% to climate plus prior growth.
