Rapid adaptation (or not) in restored plant populations.

摘要: Mismatches between the traits of a colonizing population and novel habitat can generate strong selection, potentially resulting in rapid adaptation. However, for most colonization events, it be difficult to detect adaptation or distinguish from nonadaptive evolutionary changes. Here, I take advantage replicated prairie restoration experiment compare recently established plant populations two closely located restored prairies each other their shared source test Using reciprocal transplant six years after were established, found that one showed evidence adaptation, outperforming when grown at its home site. In contrast, detected no These findings demonstrate while occur populations, may not rule. Better understanding these contexts help us use evolution our advantage, improving establishment desirable species habitats.
