Wild Arabis alpina on a rocky, Italian mountain top
An Arabis alpina plant sampled in the summer of 2021 from a large, putatively outcrossing population growing in the Apennine Mountains of central Italy. These individuals are descended from source populations for a northward range expansion which occurred post-glaciation into the French and Swiss Alps. During this expansion, A. alpina underwent a shift to increased self-fertilization. Zeitler et al. (this issue) have studied, both through simulation and comparison across populations of A. alpina, how the evolution of selfing impacts the dynamics of mutation load accumulation during species range expansions.
