Summary Plant survival in a warmer world requires the timely adjustment of biological processes to cyclical changes new environment. Circadian oscillators have been proposed contribute thermal adaptation and plasticity. However, influence temperature on circadian clock performance its impact plant behaviour natural ecosystems are not well‐understood. We combined bioinformatics, molecular biology ecophysiology investigate effects increasing temperatures functioning two closely related tree species from Patagonian forests that constitute examples different environments based their altitudinal profiles. Nothofagus pumilio , colder environments, showed major rearrangement transcriptome reduced ability maintain rhythmicity at high compared with obliqua which inhabits zones. In altitude‐swap experiments, N. but limited oscillator function zones forest, growth. Our findings show interspecific differences associated preferred niches, plasticity seedlings highlighting potential role resonating ecological warming
