“…Great Bear and Great Slave lakes (Figure 1) are unquestionably large and deep enough to support more than the one form of deepwater Cisco reported so far; both greatly exceed the surface area and depth of Lake Nipigon (Ridgway et al 2022), which supported three deepwater forms (Koelz 1929). One could argue that more deepwater Cisco remain to be reported from these two vast water bodies.…”

“…More searching in Great Slave Lake may not produce a diversity of deepwater Cisco commensurate with the lake's depth. Ridgway et al (2022) estimated based on maximum depth that Great Slave Lake should support more than four forms of Cisco and logically these would be deepwater Cisco, in addition to zenithicus. Koelz (1929) said "Virtually every haul from the chub [deepwater Cisco] nets contain a few representatives of each species…," indicating that in the Great Lakes at least, the deepwater forms were not hard to find.…”

ObjectiveWe 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.MethodsWe 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.ResultsWe 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.ConclusionThe 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.
