中文摘要：尽管欧洲对转基因作物进行了强制性的市场环境监测，但目前没有可用的方法指南或标准。本文的目的是研究大小不等的土鳖虫群体是否可作为环境监测的一种可行方法。作者对丹麦Flakkebjerg地区抗虫转基因玉米和非转基因玉米地里的土鳖虫进行了捕获研究；并用劳伦兹曲线、基尼系数和劳伦兹不对称系数等方法计算土鳖虫大小分布情况。研究共发现38种土鳖虫；抗虫转基因玉米和非转基因玉米地里的土鳖虫身体大小不等情况和平均身体大小无显著差异。研究结果表明，土鳖虫身体大小的不等对土鳖虫群体结构的细微变化很敏感，该方法是用于检测转基因植物非预期环境影响的一种潜在方法。
外文摘要：Background and Purpose: Despite the obligatory post-market environmental monitoring of genetically modified (GM) crops in Europe, there are no available methodological guidelines or standards. Our aim was to examine the suitability of carabid body size inequality as a possible method for environmental monitoring. Material and Methods: We used carabids collected by pitfall traps in both insect-resistant GM (producing a Bacillus thuringiensis toxin) and isogenic maize plots at Flakkebjerg (Denmark), within the framework of the AMIGA Project. The body size distribution was calculated using various measures of size inequality: the Lorenz curve, the Gini and the Lorenz asymmetry coefficients every month during the summer 2014. Results: A total of 6339 carabids belonging to 38 species were captured and identified. The analysis detected a significant shift in size inequality between months, indicating the larger number of individuals of smaller-sized species later in the season, but no significant difference in inequality or mean body size was found between the assemblages in GM vs. isogenic maize plots. Conclusions: We concluded that the evaluation of body size inequality was sensitive to subtle changes in the structure of the carabid assemblages, and this method had the potential to be used during monitoring of the unanticipated environmental effects of GM plants.
