Abstract

ABSTRACT Forest management constantly seeks tools that can optimize the production of goods and services. As natural archives, tree rings have proven to be effective in terms of refining the dynamics of growth on a temporal basis. This study evaluates the application of these tree rings in estimating the effect of pith eccentricity on forest growth, modeling the increase in basal area (BAI) and identifying disturbances in five coexisting species in northern Mexico. A Wilcoxon rank sum test showed significant differences, with higher radial growth in the north direction compared to the other directions. A mixed model analysis revealed two patterns of BAI growth, fast and slow growing. The former includes P. arizonica, P. engelmannii and P. leiophylla, whereas the latter comprises P. durangensis and P. lumholtzii. The fast-growing group shows a higher increment during the sapling stage. However, during subsequent stages, it presents growth rates similar to those of the slow-growing group. Finally, the percentage growth change (PGC) filter approach identified species disturbances with differential species responses, which temporarily cause uneven-aged forest. We conclude that tree rings can provide valuable information for forest management, and their temporal amplitude can be supported with information from permanent plots.

从树木年轮生长推断的髓偏心率、基面积增量和扰动

森林管理不断寻求能够优化商品和服务生产的工具。作为自然档案，树木年轮已被证明在时间基础上有效地改善生长动态。本研究评估了这些树木年轮在估计树干偏心度对森林生长的影响、模拟基底面积(BAI)的增加和识别墨西哥北部五种共存物种的干扰方面的应用。Wilcoxon秩和检验显示了显著差异，与其他方向相比，北方方向的径向生长更高。混合模型分析显示了BAI的两种生长模式:快速生长和缓慢生长。前者包括稻谷P. arizonica, P. engelmannii和P. leiophylla，后者包括durangensis和P. lumholtzii。速生组在幼树期表现出较高的增长量。然而，在随后的阶段，它表现出与缓慢生长组相似的生长速度。最后，采用生长百分率变化(PGC)滤波方法识别出具有差异物种响应的物种干扰，这些干扰暂时导致了林龄不均匀。树木年轮可以为森林管理提供有价值的信息，其时间振幅可以得到永久样地信息的支持。

期刊介绍： Tree-Ring Research (TRR) is devoted to papers dealing with the growth rings of trees and the applications of tree-ring research in a wide variety of fields, including but not limited to archaeology, geology, ecology, hydrology, climatology, forestry, and botany. Papers involving research results, new techniques of data acquisition or analysis, and regional or subject-oriented reviews or syntheses are considered for publication. Scientific papers usually fall into two main categories. Articles should not exceed 5000 words, or approximately 20 double-spaced typewritten pages, including tables, references, and an abstract of 200 words or fewer. All manuscripts submitted as Articles are reviewed by at least two referees. Research Reports, which are usually reviewed by at least one outside referee, should not exceed 1500 words or include more than two figures. Research Reports address technical developments, describe well-documented but preliminary research results, or present findings for which the Article format is not appropriate. Book or monograph Reviews of 500 words or less are also considered. Other categories of papers are occasionally published. All papers are published only in English. Abstracts of the Articles or Reports may be printed in other languages if supplied by the author(s) with English translations.
