Data from: Asymmetric micro-evolutionary responses in a warming world: Heat-driven adaptation enhances metal tolerance, but not vice versa

We investigated how prior adaptation to either high temperature or copper
(Cu) contamination influences subsequent tolerance to the other stressor
in populations of the freshwater zooplanktonic rotifer Brachionus
calyciflorus (Pallas 1766). Using an experimental evolution approach, we
subjected populations to either gradually increasing Cu levels, elevated
temperature, or control conditions over multiple generations.
Subsequently, we conducted a common garden experiment to assess the effect
of selection history on population tolerance. We found that heat-adapted
populations exhibited increased tolerance to Cu, whereas Cu-adapted
populations showed no enhanced tolerance to high temperatures.
