Abstract

Previous studies have shown that plant–pollinator mutualistic interactions experience highly interannual variation. Given that pollinators often move across multiple plant species, the plant‒plant interactions that take place via heterospecific pollen (HP) transfer may also vary temporally, which could have important implications for floral evolution and community assembly. Here, we evaluated the interannual variation in plant–pollinator networks and plant‒plant heterospecific pollen transfer (HPT) networks of a subalpine meadow community in Southwest China for three consecutive years. The interactions largely varied between years for both network types. The composition of donor-species HP deposited on the plants varied less than did the visit composition of the pollinators, which suggested that HP could be transferred from identical donor species to recipient species through different shared pollinators between years. The plant species were at more similar positions in the HPT network than they were in the plant–pollinator network across years. Moreover, the more generalized plant species in the plant–pollinator network tended to export their pollen grains and more strongly influence HPT. We evaluated the relatively stable structure of the HPT network compared with the plant–pollinator network, which represents an important step in the integration of plant–pollinator and plant‒plant interactions.
亚高山草甸植物-植物花粉传递而非植物-传粉者网络的相对稳定的年际变化
先前的研究表明,植物-传粉昆虫的互惠相互作用经历了高度的年际变化。考虑到传粉昆虫经常在多种植物物种之间移动,通过异性花粉(HP)转移发生的植物-植物相互作用也可能随时间变化,这可能对花的进化和群落组装产生重要影响。在这里,我们连续三年评估了中国西南亚高山草甸群落的植物-传粉者网络和植物-异源花粉转移(HPT)网络的年际变化。这两种网络类型的交互作用在不同年份有很大差异。附着在植物上的供体物种HP的组成变化小于传粉昆虫的访问组成,这表明HP可以在不同年份之间通过不同的共享传粉昆虫从相同的供体物种转移到受体物种。多年来,这些植物物种在HPT网络中的位置比在植物-传粉昆虫网络中的更相似。此外,植物-传粉者网络中更广泛的植物物种倾向于输出花粉粒,并对HPT产生更强烈的影响。与植物-传粉昆虫网络相比,我们评估了HPT网络相对稳定的结构,这代表了植物-传粉者和植物-植物相互作用整合的重要一步。

期刊介绍: Journal of Plant Ecology (JPE) serves as an important medium for ecologists to present research findings and discuss challenging issues in the broad field of plants and their interactions with biotic and abiotic environment. The JPE will cover all aspects of plant ecology, including plant ecophysiology, population ecology, community ecology, ecosystem ecology and landscape ecology as well as conservation ecology, evolutionary ecology, and theoretical ecology.
