我们修改了一种从最小个体增量数据集估计尺寸-年龄关系的方法，认识到增长不仅取决于尺寸，而且在个体之间也有很大差异，并且在几个到多个时间间隔内个体内部是一致的。该方法以一种长寿命沙漠植物的数据和一系列包括实地测量值的自相关因子为例。结果表明，基于规模和生长速度的年龄估计存在较大的自相关性，这给生态分析或管理的预测或预测带来了重大问题。
We modify a method of estimating size-age relations from a minimal set of individual increment data, recognizing that growth depends not only on size but also varies greatly among individuals and is consistent within an individual for several to many time intervals. The method is exemplified with data from a long-lived desert plant and a range of autocorrelation factors encompassing field-measured values. The results suggest that age estimates based on size and growth rates with only moderate autocorrelation are subject to large variation, which raises major problems for prediction or hindcasting for ecological analysis or management.
