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.

转基因作物具有增加食物、饲料和生物燃料产量的潜力，但在释放之前需要对作物和亲和物种进行环境风险评估，以确定它们是否会入侵。这项研究将开发在田间条件下收集数据的方法。使用标准人口矩阵种群模型、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)和入侵物种的入侵程度。处理措施将包括地点、干扰条件(农业、农村和自然)、种植密度和5种作物和杂草。方法的验证将允许在发布之前对转基因作物的侵入性进行评估。
