Abstract

This article investigates whether experimental populations of the coastal dune plant *Camissoniopsis cheiranthifolia* adapted to conditions beyond their northern geographic range limit after approximately 10 generations. Despite substantial genetic variation and novel environmental conditions beyond the range, descendants from beyond-range populations did not exhibit higher fitness or delayed reproduction compared to within-range populations when transplanted back beyond or within the range. The study suggests that persistence beyond the range may not require local adaptation and that plasticity could facilitate range expansion under climate change. These findings have implications for understanding species' responses to shifting habitats and for conservation strategies such as assisted colonization.
