Food Niche Overlap Among Neotropical Carpenter Bees (Hymenoptera: Apidae: Xylocopini) in an Agricultural System

<p>In the present study, we used niche overlap analysis and a network approach to investigate the use of floral resources by carpenter bees (<em>Xylocopa</em> spp.). We assessed the frequency of visit to different plant species and the activity time of carpenter bees in an agricult...
