Fig. 4From: Biogeography of the Phalaenopsis amabilis species complex inferred from nuclear and plastid DNAsThe effective population size over time for all accessions in the P. amabilis species complex based on the cpDNA trnH-psbA spacer using Bayesian skyline plots analyses. The Last Glacial Maximum (LGM) is green color shaded. Solid lines indicate median estimations; area between gray dash lines indicates 95Â % confidence intervalsBack to article page
