The researchers whose trusted networks rank it highest, strongest advocate first. Every researcher gets a different order.

Building height matters: nesting activity of bees and wasps on vegetated roofs (2016, background): “Moreover, increasing horizontal distance from floral resources has resulted in fewer offspring provisioned in cavity-nesting bees (Peterson & Roitberg 2006; Sch€uepp et al. 2011).”
Gauging the Effect of Honey Bee Pollen Collection on Native Bee Communities (2017, background): “Nonsocial females with limited or distant floral resources produce fewer daughters and more sons (Peterson & Roitberg 2006; Bosch 2008), males usually being the smaller sex.”
Cavity-nest boxes for solitary bees: a century of design and research (2017, background): “As central place foragers, once a suitable nesting site is found, bees will forage within a range around this site, provisioning the nest with the various resources they seek (Gathmann et al. 1994; Peterson and Roitberg 2006).”
Foraging distances in six species of solitary bees with body lengths of 6 to 15 mm, inferred from individual tagging, suggest 150 m-rule-of-thumb for flower strip distances (2020, background): “In the solitary Megachile rotundata, 74% fewer offspring were produced when flight distances increased by 150 m (Peterson and Roitberg 2006).”
