Understanding the role of mechanical isolation within Brunsvigia (Amaryllidaceae)
Short description:
- Associate floral morphology with pollinator morphology, including different forms for three widespread species: Brunsvigia radulosa, B. gregaria, and B. striata.
- 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.
