Gene flow, dispersal, and nested clade analysis among populations of the stonefly Peltoperla tarteri in the southern Appalachians

We examined the genetic structure and phylogeography of populations of the stonefly Peltoperla tarteri in the Southern Appalachians to determine the extent and likely mechanism for dispersal of this stream insect. A 454‐base‐pair (bp) portion of the mitochondrial control region was sequenced from a...

Description
Summary:We examined the genetic structure and phylogeography of populations of the stonefly Peltoperla tarteri in the Southern Appalachians to determine the extent and likely mechanism for dispersal of this stream insect. A 454‐base‐pair (bp) portion of the mitochondrial control region was sequenced from a minimum of 20 individuals from eight populations. Pairwise FST and exact tests showed high levels of differentiation among almost all populations except those on the same stream. amova analysis detected significant genetic differentiation between streams within drainages (φSD = 0.14, P
