Intraspecific variation in Podostemum ceratophyllum (Podostemaceae): evidence of refugia and colonization since the last glacial maximum.

American journal of botany - 1 Jan 2012

Fehrmann Susie, Philbrick C Thomas, Halliburton Richard

Abstract excerpt

PREMISE OF THE STUDY: Intraspecific variation among 20 populations of Podostemum ceratophyllum Michx. was investigated to test the hypothesis of range expansion from southern refugia since the last glacial maximum. METHODS: Six noncoding regions of chloroplast DNA were sequenced in 60 individuals. Populations were divided into two groups, north and south of the glacial boundary, in addition to isolated...
