There are many anthropogenic threats to the health and biodiversity of pollinators. However, wild bees can often thrive in urban areas. This is attributed to several factors, including the planting of many ornamental flowers and edible plants, as well as weedy floral species growing in urban ecosystems. This sets a precedent to determine how floral communities can best promote wild bee diversity in the city. To do this, we look at the mechanisms of how floral communities shape wild bee communities on the island of Montreal. Specifically, we analyze how floral trait composition determines wild bee richness. We test two separate sets of hypotheses – the floral resource diversity hypothesis (a greater diversity of nectar concentration and corolla length in the floral community will result in a greater wild bee richness) and the floral resource quality hypothesis (a floral community made up primarily of an optimal nectar concentration and corolla length will result in a greater wild bee richness). This will allow us to make planting recommendations to citizens to help them foster rich wild bee communities in the city.
