非本地植物的气候生态位保守性在很大程度上取决于其在本地范围内的气候生态位宽度
对非本地物种传播预测的信心依赖于生态位保守假说,该假说认为气候生态位随时间和空间的变化而保持不变。由于通过相同的引入途径(园艺,无意)引入的植物往往具有一些相同的引入过程和生物学属性,因此生态位保守性的程度可能受到特定属性物种引入的方式和时间的影响。我们通过协调和内核平滑比较了本地(全球)和入侵范围(西班牙大陆)之间实现的气候生态位。我们计算了158种植物的生态位保守性指标(即重叠、不填充、稳定性、扩张和开拓)。生态位稳健性指标与植物的引种途径、最短停留时间、生长形式和本地气候生态位宽度有关。平均而言,生态位稳定性占生态位占用的75%,约61%的物种出现了一定程度的生态位转移,但转移的幅度大多较小。气候生态位对一年生和多年生草本植物、很久以前引进的植物以及在其原生范围内具有广泛气候生态位的植物最为保守。引入途径的影响不显著。生态位保守性指标既不能用最小停留时间与引种途径的相互作用来解释,也不能用生长形式来解释。自然生态位宽度是生态位保守性指标中最重要的相关因子。合成。非本地植物在其入侵地和本地地的气候条件基本相似,这种模式伴随着频繁的小生态位变化而共同发生。这些结果在很大程度上支持了小生境保守主义假说。这增强了对非本地植物传播预测模型的信心。这项研究强调,生态位保守性更好地解释了植物应对广泛气候条件的能力,而不是其引进历史或生长形式。

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 We do not publish papers concerned solely with cultivated plants and agricultural ecosystems.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.
