摘要
前提:在授粉者受限的情况下,专门的授粉综合征可能会朝着截然不同的反应方向进化:一种普遍的综合征,具有更强的授粉者吸引力、授粉者奖励和花粉转移能力;或者是自花授粉综合征,具有更强的自身花粉沉积能力,但授粉者吸引力和花粉转移能力下降。嗡嗡授粉综合征专门探索雌性振动蜂作为授粉者。然而,在大西洋森林(AF)地区的高山地带,振动蜂的授粉活性较低。本研究调查了在大西洋森林区的山地地区,特化的嗡嗡授粉综合征是否会向另一种花卉综合征演化,并将广义综合征和自交综合征作为替代反应:方法:我们利用嗡嗡授粉的Miconia中的一个品系作为研究系统,对比了山地AF特有种和非特有种的花特征。我们测量并验证了花的性状,这些性状是授粉者吸引力、奖励获取、花粉传递能力和自花粉沉积的替代物。我们通过系统进化比较方法推断了花朵性状的进化过程:结果:非洲花卉特有物种选择性地进化出了更高的报酬获取能力,并更频繁地进行通性授粉。然而,AF 特有物种也有选择性地进化出较低的花粉传递能力和较强的自花授粉能力。这些模式表明了一个复杂的进化过程,该过程共同促进了泛化和自花授粉综合征:结论:嗡嗡授粉综合征在 AF 领域的高山地区可能会发生进化中断。嗡嗡授粉综合征可能比通常认为的更加易变,它允许嗡嗡授粉的植物在振动蜂是不太可靠的授粉者的环境中繁殖。
An evolutionary disruption of the buzz pollination syndrome in neotropical montane plants
Premise
Under pollinator limitations, specialized pollination syndromes may evolve toward contrasting responses: a generalized syndrome with increased pollinator attraction, pollinator reward, and pollen transfer capacity; or the selfing syndrome with increased self-pollen deposition, but reduced pollinator attraction and pollen transfer capacity. The buzz-pollination syndrome is specialized to explore female vibrating bees as pollinators. However, vibrating bees become less-active pollinators at montane areas of the Atlantic Forest (AF) domain. This study investigated whether the specialized buzz-pollination syndrome would evolve toward an alternative floral syndrome in montane areas of the AF domain, considering a generalized and the selfing syndromes as alternative responses.
Methods
We utilized a lineage within the buzz-pollinated Miconia as study system, contrasting floral traits between montane AF-endemic and non-endemic species. We measured and validated floral traits that were proxies for pollinator attraction, reward access, pollen transfer capacity, and self-pollen deposition. We inferred the evolution of floral trait via phylogenetic comparative methods.
Results
AF-endemic species have selectively evolved greater reward access and more frequently had generalist pollination. Nonetheless, AF-endemic species also have selectively evolved toward lower pollen transfer capacity and greater self pollination. These patterns indicated a complex evolutionary process that has jointly favored a generalized and the selfing syndromes.
Conclusions
The buzz pollination syndrome can undergo an evolutionary disruption in montane areas of the AF domain. This floral syndrome is likely more labile than often assumed, allowing buzz-pollinated plants to reproduce in environments where vibrating bees are less-reliable pollinators.
期刊介绍:
The American Journal of Botany (AJB), the flagship journal of the Botanical Society of America (BSA), publishes peer-reviewed, innovative, significant research of interest to a wide audience of plant scientists in all areas of plant biology (structure, function, development, diversity, genetics, evolution, systematics), all levels of organization (molecular to ecosystem), and all plant groups and allied organisms (cyanobacteria, algae, fungi, and lichens). AJB requires authors to frame their research questions and discuss their results in terms of major questions of plant biology. In general, papers that are too narrowly focused, purely descriptive, natural history, broad surveys, or that contain only preliminary data will not be considered.
