Soil sand content is a driving force in structuring bee communities

open access: yesInsect Conservation and Diversity, EarlyView.
We conducted a carefully designed observational study across three soil sand content categories using Dalea purpurea that attracts a wide range of bee species and grows in different soil types. Soil sand content, not floral resource availability, affected patterns of bee distribution, and contrary to expectations, sandier sites did not host the highest
