Phylogeography and population genetics of Acanthophyllum squarrosum complex (Caryophyllaceae) in the Irano-Turanian region
Get PDFAcanthophyllum squarrosum and two closely related species, A. heratense and A. laxiusculum (Caryophyllaceae), form a complex that covers parts of subalpine steppes of the Irano-Turanian (IT) region. In this study, we explored the genetic structure and phylogeography of this complex based on partial sequences of two chloroplasts (psbA–trnH and rpl32–trnL (UAG)) and two nuclear (EST24 and nrITS) DNA regions. We analysed 80 individuals from eight populations and detected 12 chloroplast haplotypes, 16 and eight nuclear alleles in EST24 and nrITS sequences, respectively. Phylogenetic trees and haplotype networks did not show distinct genetic groups in the complex and this could be explained by incomplete lineage sorting or introgression between species. Divergence time analysis revealed a Quaternary origin for A. squarrosum complex at approximately 1.8 million years ago (Mya) and the neutrality test results indicated that this complex experienced a recent population expansion. AMOVA analysis of the chloroplast regions showed a significant genetic differentiation among populations and low genetic differentiation within populations, but opposite results were found with nuclear markers, implying introgression between A. squarrosum complex populations

Impact of climate change implies the northward shift in distribution of the Irano-Turanian subalpine species complex Acanthophyllum squarrosum
Get PDFIn this study, we used maximum entropy modeling to predict the climate change effects on the distribution range of a subalpine steppe flora species complex, Acanthophyllum squarrosum (Caryophyllaceae). We used data from four different models, with two representative concentration pathways of climate scenarios in modern time, 2030, 2070 and 2080. Our results showed that A. squarrosum has a suitable habitat in ca. 1 million km² (33% of our study area) and will likely experience a northward shift, gaining new habitat in Azerbaijan, Armenia and North of Afghanistan in the near decades. Maxent model predicts A. squarrosum complex populations from southern Iran to be under treat of extinction, especially at lower altitudes regions and this prediction may concern other subalpine species found in the same region. Among the climatic variables investigated, annual mean temperature, and precipitation of warmest and coldest quarter were those that mostly affected A. squarrosum complex distribution.
