Figure 2From: ISSR and AFLP analysis of the temporal and spatial population structure of the post-fire annual, Nicotiana attenuata, in SW UtahUPGMA dendrograms based on the Jaccard similarity index calculated from an AFLP analysis of N. attenuata populations collected at three different sites. A: DI Ranch (17 individuals); B: Motoqua Burn and Wash (25 individuals); C: Shivwits Reservation (23 individuals) collected over a number of different years. Sample codes are given in Table 1. While substantial genetic variation was found, this variation was not organized in time.Back to article page
