Reconstructing the phylogeographic history of Spiranthes lucida: evidence of possible glacial refugia.

Spiranthes lucida is perhaps the most unusual and least studied species in the genus. Spiranthes lucida is only found in eastern North America, yet is most closely related to a clade of primarily western North American species. Furthermore, S. lucida has a highly fragmented natural distribution and a unique pollination strategy within the genus. Its geographic distribution is composed of 4 major and 4 minor disjunct metapopulations including the Ozark Plateau, southern Great Lakes, Appalachian Mountains, and northern NY and New England. Though it has a wide geographic range, S. lucida is rarely common on the landscape, and is a listed species of conservation concern in 17 of the 31 states and providences it occurs in. To assess the phylogeographic history and conservation status of this rare species, the population genetics of S. lucida was assessed utilizing microsatellites derived from Illumina Sequencing.
