Understanding the role of mechanical isolation within Brunsvigia (Amaryllidaceae)

Short description:

1. Associate floral morphology with pollinator morphology, including different forms for three widespread species: Brunsvigia radulosa, B. gregaria, and B. striata.
2. Determine the mechanisms driving pollinator shifts within Brunsvigia, specifically the importance of mechanical isolation (in addition to behavioral isolation) by looking at widespread occurring species indicated in objective 1.
