| Summary: | Cisco form diversity overlaps with glacial lake coverage in North America. A recent hypothesis proposes that secondary contact among refugial cisco lineages during retreat of the Laurentide Ice Sheet was the basis for the geography of cisco diversity in North American lakes. Glacial lake coverage in North America is also a map of Mysis diluviana distribution, a glacial relic species found in lakes including the Laurentian Great Lakes. The presence of Mysis increases isotopic niche size of cisco, a necessary condition for Mysis to be a key element of cisco clade diversification. We reviewed literature on cisco forms in North American lakes to determine if cisco diversity is related to an ecological opportunity gradient, maximum lake depth with the presence of Mysis. Cisco form diversity increases with lake maximum depth in North America in the presence of Mysis with deeper lakes increasingly likely to hold multiple forms. Lakes without Mysis had only one cisco form and were shallower in general.
