Polley&Wilsey_FE_2018_data

Data were collected from a total of 56, 1 m x 1 m patches planted to various combinations of perennial grassland species in central Texas, USA. Data were collected during years 2008-2012 and include aboveground net primary productivity (g/m2) and species abundance-weighted (community-weighted) values of specific leaf area (m2 leaf area per kg dry weight).

本数据集的数据采集自美国德克萨斯州中部共计56个1米×1米的样地，各该样地均种植有不同组合的多年生草本植物物种。数据采集时段为2008年至2012年，涵盖地上净初级生产力（aboveground net primary productivity，单位：g/m²）以及基于物种多度加权（群落加权）的比叶面积（specific leaf area，单位：m²叶面积/千克干重）的观测值。
