Effects of nutrient addition on foliar nutrient concentrations and leaf morphology of the four most common tree species of a montane forest in Ecuador.

Given are the absolute values for the control treatment and the percental effects of the treatments. Asterisks indicate significant differences to control (P<0.05). The number of sampled trees was for Graffenrieda emarginata: 5 (control), 6 (+N), 6 (+P) and 6 (+NP), for Myrcia sp.: 6, 5, 5 and 6, for Hieronyma fendleri 2, 5, 5 and 3 and for Alchornea lojaensis: 5, 4, 5 and 4.本数据集提供了对照处理的绝对数值以及各处理的百分比效应。星号代表处理组与对照组存在显著差异（P<0.05）。各采样树种的样本数量如下：格拉夫凹冠花（Graffenrieda emarginata）：对照组5株、+N处理6株、+P处理6株、+NP处理6株；美丁花属未定种（Myrcia sp.）：6、5、5、6株；芬德勒希罗尼木（Hieronyma fendleri）：2、5、5、3株；洛哈阿楝（Alchornea lojaensis）：5、4、5、4株。
