Reduced nest development of reared Bombus terrestris within apiary dense human-modified landscapes

Abstract Wild bees are in decline on a local to global scale. The presence of managed honey bees can lead to competition for resources with wild bee species, which has not been investigated so far for human-modified landscapes. In this study we assess if managed honey bee hive density influence nest...
