Persistence and invasiveness of genetically modified crops and compatible species

转基因作物有可能增加粮食、饲料和生物燃料的产量，但在释放之前需要对作物和相容物种进行环境风险评估，以确定它们是否会成为入侵物种。这项研究将开发在野外条件下收集数据的方法。利用标准人口统计学矩阵种群模型、敏感性和弹性分析以及生命表响应实验（LTRE），我们将量化相对于已知作物（非入侵）和入侵物种的入侵性。处理将包括地点、干扰情况（农业、农村和自然）、植物密度和5种作物和杂草。方法的验证将允许在转基因作物投放前对其侵入性进行评估。

Genetically modified crops have the potential to increase food, feed and biofuel production, but an environmental risk assessment is required of both crops and compatible species prior to release to determine if they will become invasive.This research will develop methods to gather data under field conditions. Using standard demographic matrix populations models, sensitivity and elasticity analysis, and Life Table Response Experiments (LTRE) we will quantification invasiveness, relative to known crop (non-invasive) and invasive species. Treatments will include location, disturbance regime (agricultural, ruderal and natural), plant density and 5 crop and weedy species. Validation of methods will allow invasiveness of GM crops to be evaluated prior to release.
