As other Mediterranean conifers, <em>J. phoenicea<\/em> populations show moderate levels of genetic diversity and interpopulational differentiation. The pattern of distribution of genetic diversity seems highly influenced by the climatic fluctuations which occurred in the Pleistocene.<\/p>\n<p><strong>Context<\/strong> It has been stated that the genetic structure of Mediterranean conifers is mediated by the historical climatic changes and the geological rearrangements which occurred in the Mediterranean Basin. <em>J. phoenicea<\/em> provides an excellent example to test how its genetic structure is influenced by these events.<br \/>\n<strong>Aims<\/strong> In this work, we study the amount and distribution of genetic diversity of <em>J. phoenicea<\/em> complex, in order to evaluate its taxonomic status and to reveal underlying phylogeographic patterns.<br \/>\n<strong>Methods<\/strong> The molecular diversity was analyzed for 805 individuals from 46 populations throughout its distribution range using AFLP markers. Principal coordinate analysis, analysis of molecular variance (AMOVA), and Bayesian-based analysis were applied to examine the population structure.<br \/>\n<strong>Results<\/strong> AFLP markers revealed moderate levels of intrapopulation genetic diversity, pairwise genetic differentiation, and a clear pattern of isolation by distance. Bayesian analysis of population structure showed five clusters related to the taxonomic status of <em>J. phoenicea<\/em> and <em>J. turbinata<\/em>, and a geographic pattern of genetic structure in <em>J. turbinata<\/em>.<br \/>\n<strong>Conclusion<\/strong> All the analysis separate <em>J. phoenicea<\/em> from <em>J. turbinata<\/em>. For <em>J. turbinata<\/em>, up to four groups can be distinguished from a phylogeographic point of view. The genetic structure of <em>J. turbinata<\/em> seems highly influenced by climatic and geologic fluctuations occurring since the Oligocene.<\/p>\n<p>Keywords<br \/>\nAFLP markers, Biogeography, Cupressaceae, Genetic diversity, Inter-populational differentiation, Taxonomy<\/p>\n<div class='altmetric-embed' data-badge-type='donut' data-doi='10.1007\/s13595-018-0741-7'  style='float: right; ' ><\/div>\n<p>Publication<br \/>\nS\u00e1nchez-G\u00f3mez, P., Jim\u00e9nez, J.F., C\u00e1novas, J.L. et al.
