摘要	To investigate the effect of past climate oscillations on the genetic diversity and demographic history of organisms in the Horqin sandlands, at the margin of the monsoonal zone in northern China. We selected Atraphaxis manshurica as a model and examined the spatial genetic structure in populations of this species across most of its covered range. Five haplotypes were identified on the basis of two chloroplast DNA sequences (psbK-psbI and psbB-psbH) in 127 individuals from 11 natural populations. The total genetic diversity (H-T = 0.437) of A. manshurica is low compared with species to the west in arid northwestern China, outside of monsoonal influence. Analysis of molecular variance (AMOVA) indicates that genetic differentiation primarily occurred among two geographical groups distinguished by spatial analysis of molecular variance (SAMOVA). The BEAST molecular clock approach revealed that genetic divergence of the species mostly occurred in middle-late Pleistocene, in accordance with the periodic glacial periods and accompanying monsoonal changes. From species distribution modeling (SDM), we found that the species experienced range contraction and southward retreat during the Last Glacial Maximum (LGM). The current genetic pattern and demographic history may have thus been shaped by glacial interglacial cycles and changes of habitat since the middle Pleistocene. (C) 2015 Elsevier Ltd.
