Local effects of ecosystem engineers on biodiversity can scale up to the landscape level, stressing the importance of ecological processes as determinants of species richness at larger spatial scales. In harsh environments, cushion plants often act as ecosystem engineers given their ability to buffer extreme abiotic conditions, thus providing unique and more favorable niches for the establishment of less stress‐tolerant plant species. We assessed if facilitation by cushion plants influences patterns of plant diversity at increasing spatial scales.

补丁级别的促进在区域规模上促进了安第斯山脉植物的多样性

生态系统工程师对生物多样性的局部影响可以扩大到景观水平，从而强调了生态过程作为更大空间尺度上物种丰富度的决定因素的重要性。在恶劣的环境中，缓冲植物由于能够缓冲极端的非生物条件而经常充当生态系统工程师，从而为建立耐逆性较低的植物物种提供了独特且更有利的生态位。我们评估了坐垫植物的促进作用是否会在空间尺度上影响植物多样性的格局。
