The accessibility of large-bodied species and their characteristically &lt;/span&gt;&lt;span style=&quot;font-family: arial, helvetica, sans-serif; font-size: x-small;&quot;&gt;high levels of genetic polymorphism make them excellent ecological and evolutionary models for studies on the &lt;/span&gt;&lt;span style=&quot;font-family: arial, helvetica, sans-serif; font-size: x-small;&quot;&gt;phylogeography, phylogenetics, and conservation of organisms in fragmented populations. This study aims to elucidate the &lt;/span&gt;&lt;span style=&quot;font-family: arial, helvetica, sans-serif; font-size: x-small;&quot;&gt;biodiversity, systematics, and distributions of genetic lineages within the genus &lt;em&gt;Oreohelix&lt;/em&gt; at the northern and western &lt;/span&gt;&lt;span style=&quot;font-family: arial, helvetica, sans-serif; font-size: x-small;&quot;&gt;periphery of their range.&lt;/span&gt;&lt;br&gt;&lt;span style=&quot;font-family: arial, helvetica, sans-serif; font-size: x-small;&quot;&gt;&lt;strong&gt;Results&lt;/strong&gt;: We found four mitochondrial clades, three of which are putative subspecies of &lt;em&gt;Oreohelix subrudis&lt;/em&gt;. One clade was &lt;/span&gt;&lt;span style=&quot;font-family: arial, helvetica, sans-serif; font-size: x-small;&quot;&gt;geographically widespread, occurring within numerous sites in Cypress Hills and in the Rocky Mountains, a second was &lt;/span&gt;&lt;span style=&quot;font-family: arial, helvetica, sans-serif; font-size: x-small;&quot;&gt;geographically restricted to the Rocky Mountains in Alberta, and a third was restricted to the Cypress Hills region. A fourth &lt;/span&gt;&lt;span style=&quot;font-family: arial, helvetica, sans-serif; font-size: x-small;&quot;&gt;clade was the small-bodied species, &lt;em&gt;O. cooperi&lt;/em&gt;. ITS2 sequence and screening data revealed three genetic clusters, of which &lt;/span&gt;&lt;span style=&quot;font-family: arial, helvetica, sans-serif; font-size: x-small;&quot;&gt;one was &lt;em&gt;O. cooperi&lt;/em&gt;. Cluster 1 contained most individuals in COI clade X and some from clade B and cluster 2 &lt;/span&gt;&lt;span style=&quot;font-family: arial, helvetica, sans-serif; font-size: x-small;&quot;&gt;was predominantly made up of individuals from COI clades B and B′ and a few from clade X. ITS2 alleles &lt;/span&gt;&lt;span style=&quot;font-family: arial, helvetica, sans-serif; font-size: x-small;&quot;&gt;were shared in a narrow contact zone between two COI clades, suggestive of hybridization between the two.&lt;/span&gt;&lt;br&gt;&lt;span style=&quot;font-family: arial, helvetica, sans-serif; font-size: x-small;&quot;&gt;&lt;strong&gt;Conclusions&lt;/strong&gt;: A sky island known as Cypress Hills, in southeastern Alberta, Canada, is a biodiversity hotspot &lt;/span&gt;&lt;span style=&quot;font-family: arial, helvetica, sans-serif; font-size: x-small;&quot;&gt;for terrestrial land snails in the genus &lt;em&gt;Oreohelix&lt;/em&gt;. The observed phylogeographic patterns likely reflect reproductive isolation &lt;/span&gt;&lt;span style=&quot;font-family: arial, helvetica, sans-serif; font-size: x-small;&quot;&gt;during the Last Glacial Maximum, followed by secondary contact due to passive, long-range dispersal resulting from low &lt;/span&gt;&lt;span style=&quot;font-family: arial, helvetica, sans-serif; font-size: x-small;&quot;&gt;vagility, local adaptation, and complex glacial history.&lt;/span&gt;&lt;/p&gt;</style></abstract><issue><style face="normal" font="default" size="100%">3</style></issue></record></records></xml>
