中文摘要:转基因作物的市场环境监测是由欧盟立法的要求且已被争论多年,然而,在使用的方法上并没有达成共识。本文对步甲指标在常规市场环境监测中对转基因作物检测的适用性进行了探讨。本文的研究结合了欧洲中部五个玉米试验田的布甲群落数据。基于最丰富物种的逐渐消亡模型,或基于功能特征的最少类别模型,表明常见物种基于特征的分析可能适用于PMEM。本文提出的方法可满足PMEM要求,且可适用于大规模场合。然而,步甲相似性的阈值前应在最终得的结论前证实。
外文摘要:Post-market environmental monitoring (PMEM) of genetically modified (GM) crops is required by EU legislation and has been a subject of debate for many years; however, no consensus on the methodology to be used has been reached. We explored the suitability of carabid beetles as surrogates for the detection of unintended effects of GM crops in general PMEM surveillance. Our study combines data on carabid communities from five maize field trials in Central Europe. Altogether, 86 species and 58,304 individuals were collected. Modeling based on the gradual elimination of the least abundant species, or of the fewest categories of functional traits, showed that a trait-based analysis of the most common species may be suitable for PMEM. Species represented by fewer than 230 individuals (all localities combined) should be excluded and species with an abundance higher than 600 should be preserved for statistical analyses. Sixteen species, representing 15 categories of functional traits fulfill these criteria, are typical dominant inhabitants of agroecocoenoses in Central Europe, are easy to determine, and their functional classification is well known. The effect of sampling year is negligible when at least four samples are collected during maize development beginning from 1 April. The recommended methodology fulfills PMEM requirements, including applicability to large-scale use. However, suggested thresholds of carabid comparability should be verified before definitive conclusions are drawn.
