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.

  • A Chi-Square Test for the Association and Timing of Tree Ring-Daily Weather Relationships: A New Technique for Dendroclimatology

    Caprio, Joseph M.; Fritts, Harold C.; Holmes, Richard L.; Meko, David M.; Hemming, Deborah L.; Department of Land Resources and Environmental Science, Montanta State University, Bozeman, MT; Laboratory of Tree Ring Research, The University of Arizona, Tucson, AZ; Department of Environmental Sciences and Energy Research, Weizmann Institute of Science, Rehovot, Israel (Tree-Ring Society, 2003)
    This study introduces a new analytical procedure based on the chi-square (x²) statistic to evaluate tree- ring weather relationships. An iterative x² method, developed previously for relating annual crop production to daily values of meteorological measurements, is applied to tree-ring data and compared to results obtained from correlation and bootstrapped response function analyses. All three analytical procedures use a southern Arizona chronology (Pinus arizonica Engelm.) and the latter two use monthly average meteorological data. The x² analysis revealed most of the relationships exhibited by the correlation and response function analyses as well as new linear and nonlinear associations. In addition, cardinal values were obtained that define daily thresholds of the meteorological variables at which the limitation to growth becomes significant. Some of the associations are plausible from the physical system but require more study to confirm or refute a real cause and effect. A few associations appear to be too late in the season or too early in the previous year to affect ring width. We recommend that this x² technique be added to the existing dendroclimatic procedures because it reveals many more possible cause and effect relationships.
  • Tests of the RCS Method for Preserving Low-Frequency Variability in Long Tree-Ring Chronologies

    Esper, Jan; Cook, Edward R.; Krusic, Paul J.; Peters, Kenneth; Schweingruber, Fritz H.; Swiss Federal Research Institute WSL, Birmensdorf, Switzerland; Tree-Ring Laboratory, Lamont-Doherty Earth Observatory of Columbia University, Palisades, NY (Tree-Ring Society, 2003)
    To preserve multi-centennial length variability in annual tree-ring chronologies, the Regional Curve Standardization (RCS) method calculates anomalies from a regionally common, non-climatic age-trend function. The influence of various factors on the estimation of the regional curve (RC) and resulting RCS- chronology is discussed. These factors are: the method of calculating anomalies from the age-trend function, estimation of the true pith offset, the number of series used, species composition, and site characteristics. By applying RCS to a collection of millennium-length tree-ring data sets, the potential and limitations of the RCS method are investigated. RCS is found to be reasonably robust with respect to tested factors, suggesting the method is a suitable tool for preserving low-frequency variance in long tree-ring chronologies.
  • A Manual and Tutorial for the Proper Use of an Increment Borer

    Grissino-Mayer, Henri D.; Laboratory of Tree-Ring Science, Department of Geography, University of Tennessee, Knoxville, Tn (Tree-Ring Society, 2003)
    An increment borer is the primary tool used to collect samples for dendrochronological analyses. These are precision instruments and users should be trained in their proper use, care, and maintenance. In this paper, I describe the various parts of an increment borer and how to keep these in working condition. I provide details on how to sharpen an increment borer, properly core a tree, check for core compression ("jamming"), extract the core, and store the core for transport. I provide tips on how to clear a jammed borer and remove a borer stuck in a tree. An important topic concerns the effects of boring on trees. The majority of studies indicate that conifers are minimally affected by both fungal decay and discoloration, whereas certain hardwood species can sustain major internal damage. Plugging the holes created by coring is unnecessary.
  • Chronology Stripping as a Tool for Enhancing the Statistical Quality of Tree-Ring Chronologies

    Fowler, Anthony; Boswijk, Gretel; School of Geography and Environmental Science, The University of Auckland, Auckland, New Zealand (Tree-Ring Society, 2003)
    Replication is a key principle in tree-ring research. Dendrochronologists strive to maximise sample size to enhance the "signal" in tree-ring chronologies, often relying on crossdating to provide an effective quality control filter. However, is crossdating alone a sufficient quality test for incorporating a series into a site chronology? We address this question using an objective and automated "chronology stripping" method designed to maximise the chronology's "Expressed Population Signal" (EPS), by iteratively removing series which lower chronology EPS. A 15-site data set of Agathis australis (D. Don) Lindley is used to demonstrate the method. Results suggest that modest benefits may be gained by chronology stripping, but the quality control implicit in crossdating is indeed effective, at least for Agathis australis.
