研究报告：在北美大盆地建立了一个山区观测站网络。NevCAN（内华达州气候-生态水文评估网络）跨越2.5°的纬度范围和两个约2000 m的海拔范围，使我们能够调查树木生长与气候的关系。·方法：我们分析了木材解剖和树轮特征的四个针叶树种在不同水平的水的可用性通过比较低和高海拔人口。早材和晚材宽度以及细胞参数的年表是从2000年到2012年制定的。结果：在南方（较干燥和较温暖）的立地条件下，单叶松的细胞腔、管胞直径和细胞壁厚度较小。在高海拔地区，单叶松和柔枝松的细胞成分较大，而在云杉和长叶松的细胞成分则相反。当所有的物种和网站合并在一起，干直径呈正相关，早材解剖参数。讨论：我们已经提供了一个应用程序的一瞥，NevCAN，作为一种新的科学工具，可以允许在植物学的一般领域。特别是，我们能够调查如何在水分胁迫相关的海拔差异导致木质部解剖结构的变化。
• Premise of the study: A network of mountain observing stations has been installed in the Great Basin of North America. NevCAN (Nevada Climate-ecohydrological Assessment Network), which spans a latitudinal range of 2.5° and two elevation ranges of about 2000 m each, enabled us to investigate tree growth in relation to climate. • Methods: We analyzed wood anatomy and tree-ring characteristics of four conifer species in response to different levels of water availability by comparing a low- and a high-elevation population. Chronologies of earlywood and latewood widths, as well as cellular parameters, were developed from the year 2000 to 2012. • Results: At the southern (drier and warmer) sites, Pinus monophylla had smaller cell lumen, tracheid diameter, and cell wall thickness. Pinus monophylla and P. flexilis showed bigger cellular elements at the higher elevations, whereas the opposite pattern was found in Picea engelmannii and Pinus longaeva. When all species and sites were pooled together, stem diameter was positively related with earlywood anatomical parameters. • Discussion: We have provided a glimpse of the applications that NevCAN, as a new scientific tool, could allow in the general field of botany. In particular, we were able to investigate how differences in water stress related to elevation lead to changes in xylem anatomy.
