摘要: 全球气候变化对生态系统的影响是人类社会面临的紧迫而又严峻的挑战。气候变化带来的极端气候事件的增多, 直接影响到生态系统生产力和服务功能。近年来在气温持续上升背景下对植物-传粉昆虫互作关系影响的研究也受到了更多关注, 这些研究主要集中在两方面, 一是植物和传粉昆虫分布区的变化, 包括部分种群可能灭绝; 二是物候的变化, 即植物花期和传粉昆虫活动期的改变。植物与传粉昆虫任何一方在空间或时间上的改变, 都会导致传粉关系的错配或丢失。此外, 也可能导致植物-传粉昆虫双方的功能性状及其耦合的改变, 从而影响其互作关系的稳定。本文总结了该领域的研究进展, 强调植物-传粉昆虫互作网络结构和其时空演变的解析, 以及互作关系和功能性状重组研究的重要性。建议在今后的研究中需要关注: (1)覆盖生物多样性的多个尺度的研究; (2)对植物-传粉者互作网络的长期监测; (3)重要指示物种繁殖适合度评价; (4)植物-传粉昆虫互作双方功能性状在时间和空间尺度上的变化, 及其互作关系的重组; (5)关键植物和传粉昆虫类群的评估和保护。

Abstract:

The impact of global climate change on ecosystems is a pressing and severe challenge to society. Climate change, with its increase in extreme climate events, has a direct impact on ecosystem productivity and service functions. Recently, research has focused on the effects increasing temperatures have on plant-pollinator. These expanding studies center primarily on two topics. The first is the change in distribution areas of plants and their pollinators including the potential for extirpation of some populations. The second is the change in phenology – that is, the change in timing of plant flowering and pollinator activity. Spatial or temporal changes in plants and pollinators may cause mismatches and potential losses in the plant-pollinator relationships. In addition, it may change functional traits and coupling between plants and their pollinators. This affects the stability of their interactions. Here, we provide a literature review on research progress in this field while addressing analyses of interaction network structure, temporal and spatial changes, and the importance of studying the “rewiring” of interactive relationships and functional traits. Based on our review, we recommend paying greater attention to the following aspects for future research: (1) covering multiple scales of biodiversity, (2) long-term monitoring of plant-pollinator interaction networks, (3) measuring the fitness of important indicator species, (4) recording changes in the functional traits of plants and pollinators along spatial and temporal scales to help rewire and/or restore of their interactions and (5) evaluation and conservation of key plants and their pollinator guilds.
