Dispersal and diversification of the heathers (Erica; Ericaceae)
Open access paper published in 2019 shows the biogeographic route to spectacular diversification of the 800+ species of heathers.
A biogeographic scenario for Erica
- Infrequent colonisation limited by geographic proximity and/or niche similarity
- Drakensberg Mountains colonisation sink, not “stepping stone” between Cape and Tropical Africa
- Dramatic species radiations in Erica result of single unique dispersals over longer distances between ecologically dissimilar areas
