Gans et al. (Reports, 26 August 2005, p. 1387) provided an estimate of soil bacterial species richness two orders of magnitude greater than previously reported values. Using a re-derived mathematical model, we reanalyzed the data and found that the statistical error exceeds the estimate by a factor of 26. We also note two potential sources of error in the experimental data collection and measurement procedures.
甘斯等人（《报告》，2005年8月26日，第1387页）给出的土壤细菌物种丰富度估计值比先前报告的值高两个数量级。使用重新推导的数学模型，我们重新分析了这些数据，发现统计误差超过估计值达26倍。我们还指出了实验数据收集和测量程序中两个潜在的误差来源。
