Crimmins et al. (Reports, 21 January 2011, p. 324) presented a study that purports to show that plants in California are shifting downslope to maintain a constant water deficit. We argue that the results are limited in scope to just a handful of woody species in one part of the state and are confounded by methodological errors.
克里明斯等人（报告，2011 年 1 月 21 日，第 324 页）展示了一项研究，声称加州的植物正在向坡下移动，以保持恒定的水分亏缺。我们认为，研究结果仅限于该州某一地区的少数几种木本植物，并且受到方法学错误的干扰。
