How has land-use and climate affected phenology, thorax-width and proportional abundance of Bombus terrestris and Bombus lucorum in southern Sweden?
Bumblebees and other pollinators have recently experienced population and diversity declines linked to habitat loss and fragmentation due to land use change. A previous study in Sweden showed a big shift in bumblebee community composition, where the Bombus terrestris complex (B. terrestris, Bombus lucorum) highly increased in relative abundance, but the relative contribution of the two different s
