From: Are adaptation costs necessary to build up a local adaptation pattern?
Juvenile survival, measured as the proportion of individuals surviving to adulthood on the novel hosts at generation 15 (a) and 25 (b). White symbols: lines evolving on cucumber, the ancestral host; black symbols: lines evolving on pepper; gray symbols: lines evolving on tomato. Adaptation can be visualized by comparing pepper lines on pepper and tomato lines on tomato to cucumber lines on pepper or on tomato, respectively. The correlated response can be visualized by comparing pepper lines on tomato and tomato lines on pepper to cucumber lines on tomato or on pepper, respectively. Vertical lines correspond to the standard error of the mean, measured as the variation among selection lines of each selection regime.
