Beyond dispersal limitation : drivers of fine-scale population structure in two common solitary wild bees
In landscapes shaped by intense agriculture, even common bee species may face limits to their dispersal capacity. We explored how spatial isolation and land-use types influence the genetic population structure of two generalist mining bees – Andrena haemorrhoa and A. nigroaenea – which differ in body size and putative dispersal potential, yet share similar ecological niches. Using a network of iso
