本研究表明，估计物种数量的动物或植物群落的样品使用相对丰度分布的可能性。我们使用对数丰度-物种-秩序图，并推导出两个新的基于对数序列和对数正态分布的估计量。在小到中等的样本量，这些估计似乎比以前的参数和非参数估计更精确。我们使用来自文献中171个已发表的中型到大型动植物群落的样本来测试我们的估计量。通过这一点，我们表明，我们的新估计也定义了精度的限制。
The present study demonstrates the possibility of estimating species numbers of animal or plant communities from samples using relative abundance distributions. We use log‐abundance–species‐rank order plots and derive two new estimators that are based on log‐series and lognormal distributions. At small to moderate sample sizes these estimators appear to be more precise than previous parametric and nonparametric estimators. We test our estimators using samples from 171 published medium‐sized to large animal and plant communities taken from the literature. By this we show that our new estimators define also limits of precision.
