Abstract

There is wide consensus that climate change will seriously impact flowering plants and their pollinators. Shifts in flowering phenology and insect emergence as well as changes in the functional traits involved can cause alterations in plant-pollinator interactions, pollination success and plant reproductive output. Effects of rising temperatures, advanced snowmelt and altered precipitation patterns are expected to be particularly severe in alpine habitats due to the constrained season and upper range margins. Yet, our understanding of the magnitude and consequences of such changes in life history events and functional diversity in high elevation environments is incomplete.

This special issue collects novel insights into the effects of climate change on plant-pollinator interactions in individual plant species and on network structure of entire plant and pollinator communities in alpine ecosystems. Using simulated changes of earlier snowmelt, natural gradients of variation in temperature, precipitation and snowmelt, or a long-term monitoring approach, these studies illustrate how plant species, plant communities, and pollinators respond to variation in environmental conditions associated with scenarios of ongoing climate change.

The collection of papers presented here clearly demonstrates how spatial or temporal variation in the environmental climatic context affects flower abundances and plant community composition, and the consequences of these changes for pollinator visitation, pollination network structure, pollen transfer dynamics, or seed production. As changes in the availability of flowers, fruits, and seeds are likely to impact on other trophic levels, the time is ripe and pressing for a holistic multitrophic view of the effects of climate change on biotic interactions in alpine ecological communities.

气候变化对植物授粉者相互作用的影响及其多营养后果
气候变化将严重影响开花植物及其传粉昆虫,这一点已得到广泛共识。开花物候和昆虫出现的变化以及相关功能特征的变化会导致植物与授粉昆虫之间的相互作用、授粉成功率和植物生殖产量发生改变。气温升高、融雪期提前和降水模式改变对高山栖息地的影响预计将尤为严重,因为高山栖息地的季节和范围上限受到限制。本特刊收集了气候变化对高山生态系统中单个植物物种中植物与传粉昆虫相互作用以及整个植物和传粉昆虫群落网络结构的影响的新见解。这些研究利用模拟早期融雪的变化、温度、降水和融雪的自然梯度变化或长期监测方法,说明了植物物种、植物群落和传粉昆虫如何对与持续气候变化情景相关的环境条件变化做出反应。本文收集的论文清楚地表明了环境气候背景的空间或时间变化如何影响花朵丰度和植物群落组成,以及这些变化对传粉昆虫的访问、传粉网络结构、花粉传递动态或种子生产的影响。由于花朵、果实和种子供应量的变化很可能会影响到其他营养级,因此从整体的多营养级视角来研究气候变化对高山生态群落中生物相互作用的影响的时机已经成熟,而且迫在眉睫。
