森林物种组成在佛罗里达是敏感的水文变化，伴随着小的海拔变化。本研究利用年轮学技术，探讨湿地松的生长过程。湿地松（湿地松）和沼泽松（Pinus palustris Mill.）（长叶松）沿着一个水文梯度，从中温带平地到干旱沙丘，对气候波动（温度、降水、河流流量和帕尔默干旱严重程度指数）作出反应。种间和种内的生长反应进行了比较之间的旱生沼泽湿地松阴谋，一个过渡区的阴谋，包含两个物种，和一个中湿地松阴谋。湿地松个体的生长与地下水位较浅的地点的可用水量增加呈负相关（
Forest species composition in Florida is sensitive to changes in hydrology that accompany small shifts in elevation. In this study, we use dendrochronological techniques to determine how the growth of Pinus elliottii var. elliottii Engelm. (slash pine) and Pinus palustris Mill. (longleaf pine) along a hydrologic gradient from mesic flatwoods to xeric sandhills responds to fluctuations in climate (temperature, precipitation, river flow, and Palmer drought severity index). Interspecies and intraspecies comparisons of growth responses were made between a xeric P. palustris plot, a transition zone plot containing both species, and a mesic P. elliottii plot. Growth of P. elliottii individuals was negatively correlated with increased water availability on sites with a shallow water table (
