dc.description.abstractAs climate change volatilizes environment conditions, it is more important than ever to understand how (and if) organisms adapt to altered thermal environments. A basic scientific understanding of thermal adaptation in marine diatoms is particularly imperative, given their substantial ecosystem services and rich applied value. Here, we explore thermal adaptation in marine diatoms with in vitro experimental evolution of Thalassiosira Pseudonana in two different thermal environments: 16 °C and 31 °C. After over two years of putative evolution, we tested for adaptation by first characterizing the growth of each algal population at both 16 °C and 31 °C, and then running computer simulations of resource competition between 16 °C-selected populations arid 31 °C selected populations. Surprisingly, in our simulations, the 31 °C-selected algae outcompeted the 16 °C when competing at 16 °C. Similarly, the 16 °C-selected algae outcompeted the 31 °C when competing at 31 °C. This pattern of "anti-adaptation" is difficult to explain. Further research is certainly needed to elucidate our results.en_US
