摘要: 揭示长期气候变暖的遗留效应对于认识植物入侵过程具有重要意义。然而,增温遗留效应如何影响入侵植物子代及其天敌的生长仍不清楚。本研究基于2012年建立的长期增温实验平台,以入侵植物加拿大一枝黄花(Solidago canadensis)为研究对象,开展了一系列植食性昆虫取食和病原菌侵染实验,探讨了实验增温对本地来源和入侵地来源的加拿大一枝黄花子代的影响,以及增温遗留效应对3种植食性昆虫和3种病原菌的影响。结果表明,加拿大一枝黄花母代经历长期增温后,其子代生长表现出促进效应,且该效应不受昆虫取食或病原菌侵染的影响。增温遗留效应抑制了取食本地加拿大一枝黄花昆虫的生长,降低了入侵地加拿大一枝黄花的病原菌侵染率。此外,自然天敌的存在能够调节增温遗留效应和种群来源的影响。上述结果表明,长期气候变暖能够通过提高入侵植物子代的生长和防御能力进而促进入侵成功,增温遗留效应和植物母本来源对认识气候变暖对植物入侵的级联效应至关重要。

Abstract: Unraveling the legacy effects of long-term climate warming is essential to for an integrated understanding of plant invasion success. However, knowledge regarding how these legacy influences invasive offspring and natural enemies remains lacking. This work was built on a long-term warming experiment established in 2012. Here, we selected invasive Solidago canadensis and performed a series of experiments to explore the effects of experimental warming on offspring S. canadensis from its native and invaded range, as well as the legacy effect of warming on three insect species, and three pathogens. The experience of long-term maternal warming facilitated the growth of offspring from invasive S. canadensis, regardless of the presence of insects or pathogens. This experience decreased insect growth when feeding on native S. canadensis, and inhibited pathogens when infecting invasive S. canadensis. Additionally, the presence of natural enemies could modulate the legacy effects of warming and population provenance. These results suggest that long-term climate warming could facilitate invasion success via coordinated increases in growth and defense, and that legacy effects of climate warming and maternal provenance are important for understanding the cascading effects of climate warming.
