The perennial Arabidopsis lyrata is able to propagate both sexually and asexually, and this is expected to influence spatial genetic structure in the species. A fine-scale molecular study by Lundemo et al. (pp. 243–254) shows how a large, alpine population in Norway overall functions as a panmictic unit, while at the same time individual plants in smaller patches exhibit considerable clonal growth.
The photoperiod is the period of time that a plant receives light each day. The photoperiod matters to a plant as it contains information about the progress of seasons. Plants use the changing photoperiod as a cue for...
The role of fine-scale habitat heterogeneity on within-population genetic divergence is studied in North American Arabidopsis lyrata (Brassicaceae) inhabiting a sand dune landscape. Wos and Willi relate site-of-origin...
Quantifying the effects of population bottlenecks and inbreeding on genetic variation underlying fitness in natural populations is central to understanding the potential limits to natural selection. One approach is to...
