What is the primary ecological consequence of aggressive male Anthidium manicatum guarding behavior in new territories?
Answer
Effective exclusion of native pollinators from nectar and pollen resources
The intense and absolute territorial defense mounted by male Wool Carder Bees, which includes chasing away any perceived rival regardless of species, leads to a significant monopolization of floral resources. By constantly patrolling favored flowering patches for hours, the dominant male effectively denies access to large quantities of nectar and pollen to native bees and other insects utilizing those same flowers. This resource drain can severely impact the foraging success and population viability of native pollinators in areas where the introduced bee has established high local abundance.
