Rodgers III, John C. University of Georgia The doctoral dissertation research will examine the effects of anthropogenic disturbance and environmental stress on the occurrence of herbaceous alien plant species on the Georgia Sea Islands. The barrier islands provide an ideal environment for examining these relationships because of the intensity of human use and the presence of stressful habitats. Vegetation composition and environmental stress variables will be sampled in sites categorized according to human modification level, environmental stress level and habitat type on each of four islands. A factorial design and analysis of variance model will be used to test these effects. Overall descriptive patterns of alien species distribution will be identified as well. The study will be of use to managers and government agencies but in a theoretical sense will provide new results on the relationship between human disturbance and environmental stress to community invasibility.

佐治亚州约翰·罗杰斯三世（Rodgers III）博士学位论文研究将研究人为障碍和环境压力对佐治亚州海群岛草本外星植物物种的发生的影响。 由于人类使用的强度和压力大的栖息地的存在，障碍岛为检查这些关系提供了理想的环境。 植被组成和环境应力变量将根据人类修饰水平，环境应力水平和四个岛屿的栖息地类型进行分类的地点进行采样。 方差模型的阶乘设计和分析将用于测试这些效果。 还将确定外星物种分布的总体描述性模式。 这项研究将对经理和政府机构使用，但从理论上讲，这将为人类干扰与环境压力与社区无敌性之间的关系提供新的结果。
