本研究调查了中国中部一大片泥炭地的有遗嘱阿米巴群落。于2009-2010年研究了有壳变形虫群落的生态和季节变化。环境控制的调查，使用排序表明，有壳变形虫群落和地下水位（DWT）和pH值的深度之间的关系是非常弱的。这里地下水位深度解释的方差比例很小（在完整数据中仅占1.9%），表明水文控制比我们预期的要弱，比我们所知道的使用类似方法的任何研究都要弱。试图开发物种-环境（传递函数）模型或确定未来古生态学研究的指示物种是不成功的。以往对泥炭地有遗嘱阿米巴生态学的大规模研究主要局限于欧洲和北美，研究结果相对一致。我们的结果与这一共识形成鲜明对比，并表明至少在中国的矿养泥炭地中，有遗嘱阿米巴群落可能主要受不同环境变量的控制。在中国，有壳变形虫的研究相对较少，但可能被证明是在古生态学和生物监测的各种应用价值，需要进一步的工作。
This study investigates the testate amoeba communities of a large peatland in Central China. The ecology and seasonal variability of testate amoeba communities were studied during 2009–2010. Investigation of environmental controls using ordination showed that the relationship between testate amoeba communities and depth to water table (DWT) and pH are extremely weak. The small proportion of variance explained by water table depth here (only 1.9% in the full data) shows that the hydrological control is weaker than we expected in this peatland, and weaker than any study we are aware of using a similar methodology. Attempts to develop species-environment (transfer function) models or identify indicator species for future palaeoecological studies were unsuccessful. Previous large-scale studies of peatland testate amoeba ecology have been largely restricted to Europe and North America and results have been relatively consistent among studies. Our results contrast with this consensus and suggest that at least in minerotrophic peatlands in China testate amoeba communities may be primarily controlled by different environmental variables. In China, testate amoebae have been relatively little studied but may prove to be valuable for a variety of applications in palaeoecology and biomonitoring and much further work is required.
