Range map of <i>Margaritifera dahurica</i> (Middendorff, 1850).
<p>Green circles are representing recent viable populations (observed since 2000), white circles—old records (until 2000). Question mark is indicated an uncertain record from the Langry River [<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0122408#pone.0122408.ref069" target="_blank">69</a>], [<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0122408#pone.0122408.ref026" target="_blank">26</a>]. Grey areas are indicated an approximate modern species range (it is shown only for the large river systems). Species locality numbers on the map correspond to numbers in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0122408#pone.0122408.s002" target="_blank">S2 Table</a>.</p
Range map of <i>Margaritifera middendorffi</i> (Rosén, 1926) and <i>Margaritifera togakushiensis</i> (Kondo and Kobayashi, 2005).
<p>Circles—<i>M</i>. <i>middendorffi</i> locations, squares—<i>M</i>. <i>togakushiensis</i> locations. Green circles and squares are representing recent viable populations (observed since 2000), white circles—old records (until 2001), yellow squares—records without exact dates. Grey areas indicate approximate modern species ranges (showing only the large river systems). Species locality numbers on the map correspond to numbers in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0122408#pone.0122408.s003" target="_blank">S3 Table</a>.</p
