Floral syndrome in Amelanchier nantucketensis (Rosaceae). II. Bee preference and diversity associated with andropetaly
Dibble AC, Drummond FA, Laberge WE. 1997. Floral syndrome in Amelanchier nantucketensis (Rosaceae). II. Bee preference and diversity associated with andropetaly. Canadian Journal of Botany. 75(11):1860-1867
Study of bee preference for Amelancier nantucketensis (which has pollen-bearing petals) vs. Amelanchier humilis (which has normal petals). Looked at the number of bees which approached each one first. Also looked at the species and diversity of bees that visited each. The study sites were at Bangor and Orono, Maine (both in Penobscot County). 'Bee species diversity differed slightly between plant species, and guilds differed; 11 bee species were unique to Amelanchier nantucketensis, including 39 individuals of Andrena milwaukiensis, and three species were unique to Amelanchier humilis. For 29 bee species shared by both plant species, abundance on Amelanchier nantucketensis was greater than on Amelanchier humilis for 62%, less for 14%, and the same for 24 %. Bees might be attracted to Amelanchier nantucketensis less by andropetaly than by proximity of flowers to the ground, floral density, or unidentified features.' /STUDY LOCATIONS/ /BANGOR/ORONO/
