Ecological theory suggests that dispersal limitation and selection by climatic factors influence bacterial community assembly at a continental scale, yet the conditions governing the relative importance of each process remains unclear. The carnivorous pitcher plant Sarracenia purpurea provides a model aquatic microecosystem to assess bacterial communities across the host plant's north–south range in North America. This study determined the relative influences of dispersal limitation and environmental selection on the assembly of bacterial communities inhabiting S. purpurea pitchers at the continental scale.

在大陆尺度上，传播限制控制北方猪笼草植物 （Sarracenia purpurea） 中的细菌群落组装


生态学理论表明，气候因素的传播限制和选择会影响大陆尺度的细菌群落组装，但控制每个过程相对重要性的条件仍不清楚。食肉猪笼草植物 Sarracenia purpurea 提供了一个模型水生微生态系统，用于评估北美寄主植物南北范围内的细菌群落。本研究确定了传播限制和环境选择对大陆尺度上栖息着 S. purpurea 笼子的细菌群落组装的相对影响。
