蚂蚁筑巢对温带草原植物生殖物候的延迟影响
在温带生态系统中观察到,气候变暖导致蚂蚁数量增加。然而,蚂蚁活动的增加如何影响植物的发育和物候仍不清楚。在这项研究中,我们标记了一种多年生草本植物(Potentilla tanacetifolia)在有蚂蚁(Proformica)巢和没有蚂蚁(Proformica)巢的开花期的个体,以探讨蚂蚁巢对蒙古高原温带大草原植物生长和物候的影响。蚁巢同时推迟了开始和结束开花的日期,因此对花期没有影响。然而,蚁巢的存在推迟了个体的结果日期。蚁巢进一步增加了流产花的数量,从而降低了坐果率。这些观察结果表明,花期推迟破坏了植物繁殖与授粉者之间的同步性,从而降低了蚁巢的授粉效率。在气候变暖的情况下,蚂蚁的数量会随着气温的升高而增加,因此植物生殖物候期的延迟和生殖产量的减少可能会对植物的适应性和植物与节肢动物之间的相互作用产生负面影响,进而影响温带大草原多年生物种在气候变化下的抵抗力和恢复力。

期刊介绍: Plant Biology is an international journal of broad scope bringing together the different subdisciplines, such as physiology, molecular biology, cell biology, development, genetics, systematics, ecology, evolution, ecophysiology, plant-microbe interactions, and mycology. Plant Biology publishes original problem-oriented full-length research papers, short research papers, and review articles. Discussion of hot topics and provocative opinion articles are published under the heading Acute Views. From a multidisciplinary perspective, Plant Biology will provide a platform for publication, information and debate, encompassing all areas which fall within the scope of plant science.
