The biodiversity of deserts is becoming increasingly threatened due to global change including the introduction of invasive species. Desert shrubs are foundational species that can facilitate native plant communities but can also benefit exotic species. The influence of exotic plants on the establishment of benefactors from seeds or seedlings is a critical knowledge gap. We tested if the establishment, survival, or growth of seedlings for a benefactor shrub species in California was reduced by the invasive grasses that they facilitate in the field.

沙漠基础物种的建立受到外来植物和光照的限制，但不受草食或水的限制

由于包括引进入侵物种在内的全球变化，沙漠的生物多样性正日益受到威胁。沙漠灌木是基础物种，可以促进本地植物群落的发展，但也可以使外来物种受益。外来植物对从种子或幼苗中建立恩人的影响是关键的知识鸿沟。我们测试了加利福尼亚州的一个恩人灌木物种的幼苗的建立，存活或生长是否因其在田间生长的入侵草而减少。
