许多植物物种通过物候变化来应对气候变化，通常开花时间提前。然而，开花对气候条件变化的反应的变异性很大，稀有植物物种，可能具有较低的环境耐受性，可能比普通植物更不能够改变它们的物候。如果植物物种通过改变开花物候来应对气候变化，植物-传粉者的相互作用可能会被破坏。然而，对于动物授粉植物的繁殖，以及长期的种群生存来说，植物可以吸引传粉者是至关重要的。这对稀有物种来说可能特别困难，因为它们可能依赖于一种或几种传粉者。为了评估气候条件如何影响常见和稀有植物物种的物候，以及这些植物物种是否吸引潜在的传粉者，我们评估了瑞士伯尔尼低地植物园中185种原产于不同海拔地区的本土植物物种的开花开始和访花。植物从高海拔开花早，表现出更明显的物候变化比植物从低海拔，独立的物种稀有性。的概率，数量和持续时间的花访问和花游客群体的数量是独立的植物起源和物种稀有的海拔高度区。花游客群体的组成也不依赖于植物起源的海拔高度和物种稀有性。因此，罕见和常见的高山植物一般可能会通过提前开花来应对气候变化，并可能能够与传粉者建立新的相互作用。
Many plant species respond to climate change by phenological shifts, usually with an earlier flowering onset. However, the variability in flowering responses to changed climatic conditions is large, and rare plant species, which are likely to have a low environmental tolerance, may be less able to shift their phenology than common ones. If plant species respond to climate change by shifting their flowering phenology, plant–pollinator interactions may become disrupted. However, it is vital for the reproduction of animal-pollinated plants, and thus for long-term population survival, that plants can attract pollinators. This might be especially difficult for rare species as they may depend on one or few pollinator species. To assess how climatic conditions affect the phenology of common and rare plant species, and whether the plant species attract potential pollinators, we assessed flowering onset and flower visitation in the lowland Botanical Garden of Bern, Switzerland, for 185 native plant species originating from different altitudinal zones. Plants from high elevations flowered earlier and showed more pronounced phenological shifts than plants from lower elevations, independent of species rarity. The probability, number, and duration of flower visits and the number of flower-visitor groups were independent of the altitudinal zone of plant origin and of species rarity. The composition of flower-visitor groups did also not depend on the altitudinal zone of plant origin and on species rarity. Thus, rare and common alpine plants may generally respond to climate change by an earlier flowering onset, and may be able to establish novel interactions with pollinators.
