在环境研究中，对包含生态重要因素且易于使用的测试系统的需求很大。本文介绍了由大型水蚤和淡色库蚊种群组成的自动化测试系统Nanocosm。Nanocosm系统允许在存在种间竞争的情况下对压力种群进行调查，这是生态系统动态中的一个非常重要的因素。利用Nanocosm系统，通过图像分析来量化这两个物种的种群的丰度和大小结构。这项技术使得能够对两个水生种群之间的相互作用进行高效、非侵入性和可靠的长期监测。我们建议将Nanocosm系统作为一种新的工具，简化竞争与环境和生态毒理学研究的结合，并用于评估应激源造成的风险。(C)2011爱思唯尔B.V.保留所有权利。
There is a great need in environmental research for test systems that include ecologically important factors and that are also easy to use. We present here the automated test system Nanocosm, which is composed of populations of Daphnia magna and Culex pipiens molestus. The Nanocosm system allows the investigation of stressed populations in the presence of interspecific competition, which is a very important factor involved in the dynamics of ecosystems. With the Nanocosm system, the abundance and size structure of populations of both species are quantified by image analysis. The technique enables a time-efficient, non-invasive and reliable long-term monitoring of interactions between two aquatic populations. We recommend the Nanocosm system as a novel tool for the simplified integration of competition into environmental and ecotoxicological research as well as for the assessment of risk due to stressors.
