Transcriptional mechanisms underlying life-history responses to climate change in the three-spined stickleback.

ABSTRACT: Phenotypic plasticity, the ability of an organism to express different phenotypes depending on the environment, provides an important mechanism by which an animal population can persist under rapid climate change. We experimentally tested both life-history and transcriptional responses of an ecological model species, the three-spined stickleback, to warm acclimation at the southern edge of its European range. We explored cross-environment genetic correlations of key life-history traits in male sticklebacks exposed to long-term temperature changes to examine whether the plasticity pattern was variable among genotypes by using a character-state approach. We also studied gene expression plasticity by analysing both whole-transcriptome and candidate gene expression in brain and liver. Male sti
