Two transplant gardens were used, one in Quebec and the other in North Carolina. The home transplants always allocated more energy to reproduction than any others. Plants from Mississippi failed to flower in Quebec. Those from Quebec did not survive the North Carolina summer. (2) Stage-specific selection coefficients indicate that the southern populations are increasingly selected against in Quebec as the season progresses. At the adult stage, plants from Quebec have a strong selective advantage. Similarly, the northern plants are completely selected against in North Carolina.Read More
