ABSTRACT Urbanization alters insect pollinator diversity and foraging ranges, while also providing novel habitats. Common urban landscape features, such as roads buildings, may alter the ability of pollinators to move forage throughout landscape. In this study, we aimed quantify effects common features on movement. We focused roads, forest fragments, lawns, community gardens. studied five garden sites surrounding them in Raleigh, North Carolina, USA. To measure movement across each feature, placed clusters potted cucumber plants either side a feature added fluorescent dye powder stamens flowers. After 7 h, collected counted number grains transferred stigma. conducted 10‐min visitation observations at cluster assess whether low was linked transfer. Buildings had lowest estimated transfer, gardens were intermediate, lawns fragments highest Although associated with buildings rates, overall poor predictor The most visitors observed Apis mellifera , Bombus spp., Xylocopa virginica indicating our results are likely primarily representative these large, generalist bee species. Our study highlights heterogeneity spaces pollinators. demonstrate which facilitate inhibit movements thereby provide an empirical basis map functional connectivity. This information can help cities identify create connected networks habitat for essential using geospatial methods, inform research about resource accessibility energetics
