The soil seed bank is an important ecosystem component that can be pivotal for long‐term persistence of many plant species, especially after disturbances followed by the invasion of alien weeds. However, many Great Basin Desert perennials produce relatively few viable seeds, while large areas of the Great Basin are currently invaded by alien weeds. This could result in dissimilarity in floristic composition between the above‐ground vegetative community and the soil seed bank, causing abrupt plant community shifts following disturbance. Therefore, we asked what is the relationship in the floristic composition between the above‐ground communities and the soil seed bank in sites where the threatened Ivesia webberi occurs?

量化大盆地西部沙漠中受威胁的Ivesia webberi的站点中的土壤种子库与植物群落组合之间的关系

土壤种子库是重要的生态系统组成部分，对于许多植物物种的长期持久生存至关重要，尤其是在受到外来杂草入侵后的干扰之后。但是，许多大盆地沙漠多年生植物产生的种子很少，而大盆地的大部分地区目前都受到外来杂草的入侵。这可能导致地上营养群落与土壤种子库之间的植物组成不同，从而导致扰动后植物群落突然发生变化。因此，我们问到受威胁的Ivesia webberi发生地点的地上群落与土壤种子库之间的植物学组成有什么关系？
