We report the development of a new quantitative method of assessing the effects of anthropogenic impacts on living beings; this method allows us to assess actual impacts and to travel backwards in time to assess impacts. In this method, we have crossed data on fluctuating asymmetry (FA, a measure of environmental or genetic stress), using Didelphis albiventris as a model, with geographical information systems data relating to environmental composition. Our results show that more impacted environments resulted in statistically higher levels of FA. Our method appears to be a useful and flexible conservation tool for assessing anthropogenic impacts.
我们报告了一种评估人为影响对生物作用的新定量方法的开发；这种方法使我们能够评估实际影响，并回溯时间来评估影响。在这种方法中，我们以白腹袋鼹为模型，将关于波动不对称性（FA，一种环境或遗传压力的度量）的数据与有关环境组成的地理信息系统数据相结合。我们的结果表明，受影响更大的环境导致FA在统计学上具有更高的水平。我们的方法似乎是一种用于评估人为影响的有用且灵活的保护工具。
