BeskrivningFunctional traits are increasingly used to understand pollinators’ responses to multivariate global changes. However, there is no comprehensive overview of their use in insect pollinator studies. We address this knowledge gap by systematically identifying and reviewing studies explicitly using functional traits focusing on insect pollinators. We summarize how traits have been used to understand how pollinators respond to global change.
Among the >200 identified studies, bees was the most studied taxon, while studies on Diptera were rare. They were mainly carried out in an agricultural landscapes in temperate regions. The most commonly studied traits related to body size and diet. Traits were often taxon-specific, highlighting the difficulty
of designing a shared trait framework across taxa.
Most studies focused on the consequences of global change, with a particular emphasis on landscape simplification and fragmentation. Some common patterns were observed across studies, such as smaller bees being more sensitive to habitat fragmentation and climate change. However, many trait-pressure relationships lacked consistency across studies, and most tested relationships were non-significant. The use of a wider array of traits, including e.g. sensory traits, based on hypotheses of mechanistic links with investigated pressures, may increase the value of trait-based approaches.
