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.

  • Twisted Increment Cores: Getting it Straight

    Young, P. J.; Cleaveland, M. K.; School of Forestry, Wildlife and Fisheries, Louisiana State University, Baton Rouge, Louisiana; Tree-Ring Laboratory, Department of Geosciences, University of Arkansas, Fayetteville, Arkansas (Tree-Ring Society, 2000)
    Increment cores that dry with a spiral twist are a problem in any study where a clear view of transverse wood anatomy is required. This problem may become acute when working with wood that is partially decomposed. After soaking cores in a urea solution, we can remove spiral twists by applying steam to the cores and gently twisting cores until they straighten. Treatment does not result in a serious distortion of ring widths.
  • Dendroclimatology of Umbrella Pine (Pinus pinea L.) in Istanbul, Turkey

    Akkemik, Ünal; Department of Forest Botany, Faculty of Forestry, University of Instanbul, Istanbul, Turkey (Tree-Ring Society, 2000)
    To determine the response of tree rings to climate, twenty cores were extracted from ten trees of Pinus pinea L. in Istanbul-Alemdag. A response function was used to characterize the relationships between tree rings and temperature and precipitation. The precipitation of the current year and the temperature at the beginning of the growing period have a significantly positive influence on the growth of the tree ring. Mean sensitivity was found to be 0.291, and it was concluded that Pinus pinea L. is a dendroclimatologically sensitive species.
  • Libocedrus Bidwillii Tree-Ring Chronologies in New Zealand

    Xiong, Limin; Palmer, Jonathan G.; Soil, Plant, and Ecological Sciences Division, Lincoln University, Canterbury, New Zealand (Tree-Ring Society, 2000)
    Twenty-three Libocedrus bidwillii (New Zealand cedar) tree-ring chronologies have been developed from New Zealand. This total consists of twelve new sites collected by the authors and eleven previously collected by others (five of which we have updated and six of which were not). Standardization of the tree-ring series from each site used a double detrending method (linear-exponential or linear regression or a horizontal detrending plus spline detrending fitted to 2/3 the length of each tree-ring series). ARSTAN modeling using the Aikaike Information Criterion (AIC) to determine the filter model removed all significant autocorrelations from the residual chronologies. The average chronology length is around 500 years, and the sites are spread over 8° of latitude (i.e.. 38°-46 °S) and nearly 10(X) m in elevation (i.e., 244-1220 m.a.s.1.). The species tends to grow slowly (mean ring-width 0.7 mm), and the tree rings have a high autocorrelation value (0.79). The average mean sensitivity was 0.17, and the average mean correlation between all radii within chronologies was 0.55. Comparison of the chronologies showed a highly consistent and significant pattern among most of the sites. There was a reduction in interchronology correlation with separation distance; however, there was no clear relationship, or an effect, due to elevation. The spatial extent and temporal length of the network of sites offers the most comprehensive opportunity for New Zealand climate reconstruction to date.
