Fig. 6From: Long-term persisting hybrid swarm and geographic difference in hybridization pattern: genetic consequences of secondary contact between two Vincetoxicum species (Apocynaceae–Asclepiadoideae)Predicted distributions of V. atratum and V. japonicum based on species distribution modeling using the MAXENT program. Predicted distributions are shown for the present time, the mid-Holocene, and the last glacial maximum (LGM)Back to article page
