Tree-Ring Bulletin, Volume 25 (1962-1963)
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.

Tree-Ring Dates from the Navajo Land Claim I. The Northern SectorThis, the first of five articles, gives the dates from specimens collected by the Navajo Land Claim Field Research teams. All specimens came from the Northern Sector of the Navajo Land Claim area. Out of a total of 237 specimens worked, 145 of them were dated and are listed here. Several specimens from each area were measured and plotted with modern cores from the area. The indices for each area are given, as well as the average indices for the Northern Sector.
Computer Programs for Tree-Ring ResearchComputer programs are described for: (1) the derivation of tree-ring indices and associated statistical parameters, (2) the dating of unknown tree-ring series against a longer master chronology using correlation techniques, (3) the calculation of cross- correlation to evaluate covariation among a large number of series, and (4) the estimation of variance components for sampled tree-ring series. General applications of these programs are illustrated by reference to an example of archaeological dating, a study of correlation among tree-ring series as a function of distance, and several ecological evaluations of tree-ring variability.
The Relation of Growth Ring Widths in American Beech and White Oak to Variations in ClimateAn analysis is made of beech from Ohio and white oak from Illinois using a stepwise multiple regression technique to evaluate ring growth and climatic relationships. Ring widths for beech are directly related to the moisture supply during August and to temperatures for May-July of the preceding year. They are equally related to moisture during June-August of the current year and somewhat dependent upon the precipitation of the previous winter. The earlywood width of white oak is directly related to available moisture during the preceding September and to moisture during the current June, and inversely related in slight degree to the temperature of April. Latewood width of oak is primarily dependent upon the availability of moisture during the current June and July but is somewhat related to the moisture during May of the previous year. Serial correlation is prominent from growth layer to growth layer in both species. The physiological relationships which may produce these results are discussed. Some relationships involving considerable lag in the growth response are possible controls of bud formation and food accumulation, while others involving more immediate response are primarily the effect of moisture stress within the tree.
