A strong ‘filter’ effect of the East China Sea land bridge for East Asia’s temperate plant species: inferences from molecular phylogeography and ecological niche modelling of Platycrater arguta(Hydrangeaceae)

Table 2 Maximum-likelihood estimates (MLEs) and lower and upper bounds of the 90% highest posterior density intervals (HPD90_Loand HPD90_Hi, respectively) of demographic parameters of Platycrater arguta from the IMA analysis of multi-locus data (cpDNA, ITS, Tpi , nSSRs)

Population rate parameters Θ_C, Θ_J, and Θ_A refer to the scaled effective population sizes (N_e) of var. sinensis (East China), var. arguta (South Japan), and the ancestral population, respectively. m_C-J and m_J-C are the scaled migration rates forward in time from var. sinensis to var. arguta and vice versa. M_C-J and M_J-C are the probabilities of migration from var. sinensis to var. arguta, per gene copy per generation and vice versa. 2N_CM_C-J and 2N_JM_J-C are the effective migration rates (number of migrants per generation). t is the time since ancestral population splitting in mutational units.
All estimates include the per gene mutation rate u, which is equal to the geometric mean of the mutation rates of all the loci. Θ_C, Θ_J, Θ_A, m_C-J, m_J-C, and t are scaled by the mutation rate, while N_C, N_J, N_A, 2N_CM_C-J, 2N_JM_J-C and T are scaled by individuals or years.
