Phenotypic plasticity may allow species to cope with environmental
variation. The study of thermal plasticity and its evolution helps
understanding how populations respond to variation in temperature. In the
context of climate change, it is essential to realize the impact of
historical differences in the ability of populations to exhibit a plastic
response to thermal variation and how it evolves during colonization of
new environments. We have analyzed the real-time evolution of thermal
reaction norms of adult and juvenile traits in Drosophila subobscura
populations from three locations of Europe in the laboratory. These
populations were kept at a constant temperature of 18ºC, and were
periodically assayed at three experimental temperatures (13ºC, 18ºC and
23ºC). We found initial differentiation between populations in thermal
plasticity as well as evolutionary convergence in the shape of reaction
norms for some adult traits, but not for any of the juvenile traits.
Contrary to theoretical expectations, an overall better performance of
high latitude populations across temperatures in early generations was
observed. Our study shows that the evolution of thermal plasticity is
trait specific, and that a new stable environment did not limit the
ability of populations to cope with environmental challenges.
