随着时间的推移，全球草原植物物种对营养添加的响应，而不是对食草动物的排斥，会增强

土壤养分和草食压力的变化是草地植物群落动态的关键驱动因素。预测植物群落将如何应对这些全球变化因素需要了解单个物种的反应，这可能受到它们在群落中的丰度和频率，以及它们的地理来源（本地vs外来），生活史（一年生vs多年生）和生长形式（草vs草）等特征的影响。我们分析了来自98个草原超过13年（739个站点年）的2414种植物的数据，以研究营养添加（施肥处理与未施肥对照）和食草动物排除（围栏处理与未围栏对照）如何改变植物群落组成。我们量化了物种特异性对组成变异的贡献，并将这些贡献与它们的优势度、共性（无论它们发生在一个处理中还是两个处理中）和特征联系起来。随着时间的推移，添加养分会增加植物群落组成的差异，而排除草食动物对植物群落组成的影响微弱且短暂。一种处理特有的植物种类在营养添加处理中变得越来越普遍，但对成分变化的贡献却小得惊人。大多数变异是由于共同的物种，特别是那些在两个处理中具有相似优势模式的物种。指示种对不同处理间组成差异的贡献率高得不成比例；这些物种更可能是优势种，在一年生植物和外来植物中都是常见的。合成。这些发现强调，全球变化对植物群落组成的影响可能是由一部分物种的变化驱动的。了解这些物种特异性反应对于预测群落动态和面对持续环境变化的生物多样性保护工作至关重要。我们的研究证明了确定全球草原成分变化的关键驱动因素的效用。

期刊介绍： Journal of Ecology publishes original research papers on all aspects of the ecology of plants (including algae), in both aquatic and terrestrial ecosystems. We do not publish papers concerned solely with cultivated plants and agricultural ecosystems. Studies of plant communities, populations or individual species are accepted, as well as studies of the interactions between plants and animals, fungi or bacteria, providing they focus on the ecology of the plants. We aim to bring important work using any ecological approach (including molecular techniques) to a wide international audience and therefore only publish papers with strong and ecological messages that advance our understanding of ecological principles.
