Cephalaria transsylvanica-based flower strips as potential food source for bees during dry periods in European Mediterranean basin countries.

The introduction of sown wildflower strips favours the establishment of pollinator communities, with special reference to social Apoidea. Here, we evaluated the late summer flowering Cephalaria transsylvanica as suitable species for strips providing food for pollinators in paucity periods. C. transs...
