| Abstract | OBJECTIVE: We propose that deepwater Cisco Coregonus artedi (sensu lato) survived Wisconsin ice advances through introgression with shallow‐water Cisco ~65 ka followed by expression of introgressed genomic fragments after the last retreat of ice from the Great Lakes ~15 ka. METHODS: We reviewed Wisconsin Glaciation in relation to putative introgression within Cisco and employed a phylogeographic approach to substantiate locations of Cisco refugia and the implications for dispersal of Cisco ahead of the last advance of Wisconsin ice. RESULT: We showed that deepwater Cisco, in contrast to shallow‐water Cisco, were very unlikely to have survived glacial advances and that a massive introgression event between both types likely occurred as the first of two Wisconsin ice advances reached the Great Lakes ~65 ka. CONCLUSION: The most‐parsimonious explanation for the distribution of deepwater Cisco involves long‐ago introgression as a precursor to its divergence from shallow‐water Cisco following the final retreat of Wisconsin ice. |
