Plant invasions can affect soil properties in the invaded habitat by altering the biotic and abiotic nature of soils through positive or negative plant-soil feedback. Litter decomposition from many invasive species enhanced soil nutrients, thereby decreasing native plant diversity and leading to further plant invasions. Here, we examined the impact of litter decomposition from an invasive plant (Sphagneticola trilobata) in a range of soils at varying depths on growth and physiology of its native congener (S. calendulacea).

生物入侵期间的植物土壤反馈：入侵植物（Sphagneticola trilobata）的凋落物分解对其天然同源物（S. calendulacea）的影响

植物入侵可以通过正或负的植物-土壤反馈改变土壤的生物和非生物性质，从而影响入侵栖息地的土壤特性。许多入侵物种的凋落物分解增强了土壤养分，从而减少了本地植物多样性并导致进一步的植物入侵。在这里，我们研究了入侵植物（Sphagneticola trilobata）在不同深度的一系列土壤中的凋落物分解对其原生同源物（S. calendulacea）的生长和生理的影响。
