人口统计数据将在检验当前植物生态学理论和预测全球变化的影响方面发挥核心作用。然而，有关生命速率的长期数据非常有限，特别是草本植物群落中的物种。在这里，我们提供了一个数据集，它具有极大的潜力来增加我们对植物人口统计过程的理解。从1932年到1972年，美国堪萨斯州海斯的研究人员每年都会绘制出混合草地草原上一系列1平方米样方中的所有个体植物的地图。时间范围和精细空间分辨率的罕见组合使人们有可能通过时间跟踪个别草本植物(或基因)，并回答诸如：个体生存和重新招募如何随降水和温度变化的问题？这些关系是如何通过与邻近的同种和异种的相互作用而改变的？数据集包括以Arc导出格式的数字化地图，整个数据集的表格，非空间版本，描述性信息...
Demographic data will play a central role in testing current theories in plant ecology and forecasting the effects of global change. However, long-term data on vital rates are very limited, especially for species in herbaceous plant communities. Here we present a data set that has great potential to increase our understanding of plant demographic processes. Every year from 1932 to 1972, researchers in Hays, Kansas (USA), mapped all individual plants in a series of 1-m2 quadrats in a mixed grass prairie. The rare combination of temporal extent and fine spatial resolution makes it possible to follow individual herbaceous plants (or genets) through time and to answer questions such as: How does individual survival and recruitment vary with precipitation and temperature? How are these relationships modified by interactions with neighboring conspecifics and heterospecifics? The data set includes the digitized maps in Arc Export format, a tabular, nonspatial version of the entire data set, descriptive informati...
