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.

Issues from 1934–2006 are freely available on the publications section of the Tree-Ring Society website. The Tree-Ring Society and the Laboratory of Tree-Ring Research at the University of Arizona partnered with the University Libraries to re-digitize back issues for improved searching capabilities and long-term preservation.

    Guiot, J.; Berger, A. L.; Munaut, A. V.; Till, Cl.; Institut d'Astronomie et de Géophysique; Laboratoire de Palynologie et Phytosociologie, Université Catholique de Louvain (Tree-Ring Society, 1982)
    An original procedure and a new mathematical technique have been developed which allowed us to obtain more reliable climatic reconstructions than with prior methods. They have been tested for different sites in Switzerland and Morocco. First, cores that were too short and cores that were not coherent enough with others were excluded, using cross-spectral analysis. Second, detrending and master chronologies were calculated. Three methods were compared: polynomial, high-pass filter, and spline indexing. An optimal detrending was obtained through comparison with climate, but there seems to be no general rule for it. More reliable and longer climatic reconstructions are made possible. A response functions technique in three steps is presented: regression after extracting principal components on monthly climatic parameters, on seasonal parameters, and on more biological parameters such as potential evapotranspiration, multiple spectral regression introducing frequency domain. This procedure provides a more complete and more dynamic view of tree growth. The transfer function method and its verification are illustrated for different sites in Morocco: three climatic parameters in Tetouan (February, May, and June temperatures) and one in Marrakech (May temperature) have been successfully reconstructed. These reconstructions are confirmed by different verifications.
  • Development of Tree-Ring Chronologies in an Ozone Air Pollution-Stressed Forest in Southern California

    Gemmill, Barbara; McBride, Joe R.; Laven, Richard D.; University of California, Davis, California; University of California, Berkeley, California; Colorado State University, Fort Collins, Colorado (Tree-Ring Society, 1982)
    The utilization of radial growth responses of trees to diagnose air pollution injury, and problems of growth defects interfering with the establishment of growth chronologies, is discussed. Cores from trees in an air pollution-stressed forest are examined for their potential to crossdate. Less than half, and usually less than a third of the trees on all plots can be crossdated, and number appears to be associated with changing conditions along a transect of elevational and pollution levels. Chronologies developed along this transect are presented.
  • Comments on Interpretation on Climatic Information from Tree Rings, Eastern North America

    Phipps, Richard L.; U. S. Geological Survey, Reston, VA (Tree-Ring Society, 1982)
    A general discussion regarding problems inherent to developing climatically sensitive tree-ring chronologies from eastern North America is presented. Tree-ring collections from eastern forests are typically not as climatically sensitive as western collections. Collections have been made from a diversity of sites, but it seems that collections from wet sites or sites of extremely shallow soils may have limited potential. The detrimental effect of crown crowding on sensitivity suggests preference be given to shade-tolerant species and to trees with less crowded crowns exposed in the canopy. Nonclimatic trends in tree-ring data are classified as growth trends and competition trends. Standardization of ring widths removes much of the growth trends, and merging individual tree chronologies into a mean collection chronology eliminates much of the competition trends of individual trees. Separation of ring width into earlywood and latewood widths, where possible, may be quite beneficial for non-pored and diffuse-porous species. However, this procedure seems to be of little value for ring-porous species.
  • Density of Tree-Ring Grids in Western North America

    Cropper, John Philip; Fritts, Harold C.; Laboratory of Tree-Ring Research, University of Arizona (Tree-Ring Society, 1982)
    The separating distance over which tree-ring chronologies are significantly correlated is investigated. Any chronology occuring within a radius of 161 km of another is estimated to contain at least half of the common variance occurring at zero separating distance. The separating distance of 161 km is used to calculate the number of nonoverlapping chronology equivalents present within the 40 -, 65 -, and 89-chronology western North American grids. The density of chronologies is calculated for these three grids in various ways. The results give conservative density estimates of five, seven, and eight sites per Mkm² for the three different tree-ring grids.
