The document summarizes a study that examined how bee communities are affected by the amount of roadside edge habitat in the landscape. Researchers characterized bee communities and the surrounding landscape at multiple sites. They found that roadside edges attract a large number of diverse bee genera, and bee communities were dominated by sunflower-feeding genera. Communities diverged significantly in sites with little roadside edge habitat available in the surrounding landscape. The researchers concluded that roadside edges provide important habitat for bees and influence the composition of local bee communities.
