Structure of plant-pollinator interaction networks as a tool for pollinator conservation
See the title in English
Pollinators such as bees, hoverflies, and butterflies have intimate relationships with the flowers they visit. They obtain food in the form of pollen and nectar while transferring pollen to plants, enabling plant reproduction through mutualistic interactions. However, not all pollinators can visit all plant species. Our two studies aimed to assemble the first plant-pollinator interaction network at the European level, depicting pollinator relationships with plants across the continent. Using this information, we mapped how interactions are organised and what implications they have for pollinator conservation. Key findings:
• The structure of plant-pollinator networks reveals a core of generalist species interacting among themselves, with specialist species attached to this core. This pattern reflects species abundance, with more abundant species forming the core. Such structures are particularly stable.
• Bees, hoverflies, and butterflies engage in different types of interaction patterns, indicating distinct roles in connecting the network.
This information can guide restoration programs by identifying pollinator needs, such as selecting a balanced mix of plant species that promotes coexistence.
