中文摘要：欧盟国家对转基因作物的市场监测是强制的。步甲对环境的变化非常敏感，因而可作为监测转基因作物影响的指标。本文的研究的目的是评估步甲指标何时何地应该用于市场监测。作者将检测到的42种步甲组成一个营养类群以用于群落计算。其中，最好的步甲指标为Pseudoophonus rufipes，它可以满足丰富度、关联度、敏感度、便于采样、足够统计力度的标准。食肉动物群落也应检测来作为生物多样性和无脊椎动物生物控制的指标。研究结果表明，步甲指标可为市场监测减少成本，并有效提高市场监测的检测能力。
外文摘要："1 Post market monitoring of GM crops is mandatory in EU states where they are grown commercially. Carabid beetles are very sensitive to environmental changes and may be used as indicators to monitor impacts of transgenic crops. This study aimed to assess which, where and when carabids should be sampled for improved postmarket monitoring.
2 Carabids were pitfall-trapped in maize fields, field margins, alfalfa and semi-natural vegetation across three regions of NE Spain, during 2 years, and three sampling dates.
3 Overall, 9193 carabids of 42 species were identified, aggregated into trophic groups and used for calculating community measures. The best indicator was Pseudoophonus rufipes (De Geer), satisfying criteria of abundance, relevance, sensitivity, ease of sampling, and sufficient statistical power. The carnivore group should also be monitored as an indicator of biodiversity and invertebrate biological control.
4 The best sampling location was the field margin where carabids are exposed to GM maize and are abundant enough to require smaller sample sizes to detect population changes.
5 Finally, sampling should concentrate around maize pollen-shed when carabid abundance is highest.
6 This study provides baseline data and shows that carabids can cost effectively improve detection capacity of postmarket monitoring."
