Other claims from this paper (8)
- Observation ISSR analyses revealed extremely low levels of genetic diversity in O. handiense.
- Observation ISSR analyses provided evidence for a recent bottleneck and for isolation-by-distance at the local scale in O. handiense.
- Observation The models pointed to a mismatch between the limited extant distribution and the extent of macroclimatically suitable areas of O. handiense.
- Observation All models predicted climatic unsuitability on Fuerteventura and Lanzarote at 21 ka.
- Observation A dramatic reduction and loss of suitable areas of O. handiense were predicted for 2050 and 2080.
- Observation The ability of O. handiense to respond quickly to predicted climate change is questioned.
- Mechanism The phylogenetic position of O. handiense points to a dispersal event from a western North American ancestor.
- Mechanism The predicted absence of suitable conditions at 21 ka supports a palaeoendemic origin and a recent founder event for O. handiense in Fuerteventura.
