Data from: Can clone size serve as a proxy for clone age? An exploration using microsatellite divergence in Populus tremuloides

In long-lived clonal plant species, the overall size of a clone has previously been used to estimate clone age. The size of a clone, however, might be largely determined by physical or biotic interactions, obscuring the relationship between clone size and age. Here, we use the accumulation of mutations at 14 microsatellite loci to estimate clone age in trembling aspen, Populus tremuloides, from southwestern Canada. We show that the observed patterns of genetic divergence are consistent with a model of clonal growth, allowing us to use pairwise genetic divergence as an estimator of clone age. In the populations studied, clone size did not exhibit a significant relationship with microsatellite divergence, indicating that clone size is not a good proxy for clone age.SSR_Data_11905036MEC-08-0315.R1This data was collected in two geographical locations: Riske Creek, British Columbia and Waterton Lakes National Park, Alberta. The data represent 14 microsatellite loci. See Ally et al. 2008 for a description of the SSRs. Any loci that did not amplify are indicated with an question mark.Riske_Creek_sizedataSee the README_SIZEDATA fileRR_SizeDataSee README_SIZEDATA Fil
