摘要: Abstract Transferring plants between populations of rare species has often been proposed to increase population size and replenish genetic variation. While this approach many advantages, it may also disrupt local adaptation. However, the scale over which adapt conditions is hard predict. To detect adaptation, we conducted reciprocal transplant experiments in field with six perennial herb, Aster amellus. We sowed seeds 2003 2004 (called ‘Experiment 2003’ 2004’) transplanted adult 2004. evaluated differences ecological habitats tested explain degree The number juveniles from was 68% 42% higher than foreign 2004’, respectively, indicating not all A. amellus adapted their conditions. Differences climate vegetation composition particularly affected In contrast seeds, did overall perform better populations. conclude that transfer a more appropriate technique conservation practice because likely prevents non-adapted genotypes establishing. Material for transfers should come, necessarily closest, but rather ecologically similar habitats.
