QuestionThe biotic resistance hypothesis states that 物種 多樣性 is a barrier for plant 生物 invasions because alien 物種 are more likely to find strong competitors as 多樣性 of native plants increases. In stressful environments, however, these negative relationships could be diluted because increased physical harshness might reduce the importance of competition as a structuring force in plant communities. Nevertheless, if nurse plants facilitate other 物種 and create more diverse vegetation patches than those found in their surroundings, the performance of invaders should be negatively related to 多樣性 within these patches. Conversely, 多樣性 would not regulate invasibility in the surroundings of nurses because these habitats are subjected to higher levels of environmental harshness. LocationA high-Andean l
