Based on analysis of the reassociation kinetics of bacterial DNA in soil, Gans et al. (Reports, 26 August 2005, p. 1387) claimed that millions of microbe species existed in 10 grams of pristine soil and that 99.9% of the diversity was lost as a result of toxic metals. We show that the data do not support these startling conclusions unambiguously.
基于对土壤中细菌DNA重缔合动力学的分析,甘斯等人(《科学》,2005年8月26日,第1387页)声称,10克原始土壤中存在数百万种微生物,并且由于有毒金属的存在,99.9%的生物多样性丧失。我们表明,这些数据并不能明确支持这些惊人的结论。
