Scaling up evolutionary responses to elevated CO2: lessons from Arabidopsis

摘要: Results from norm of reaction studies and selection experiments indicate that elevated CO2 will act as a selective agent on natural plant populations, especially for C3 species are most sensitive to changes in atmospheric concentration. Evolutionary responses may alter physiology, development rate, growth, reproduction ways cannot be predicted single generation studies. Moreover, ecological evolutionary communities have range consequences at higher spatial scales cause substantial deviations ecosystem level predictions based short-term CO2. Therefore, steps need taken identify the traits likely evolve CO2, understand how these affect net primary productivity within ecosystems. These processes scale molecular physiological occur among genotypes individual population levels, community- ecosystem-level result integrative effects different evolving simultaneously. In this review, we (1) synthesize recent investigating role plants, (2) discuss possible control points during change response with an emphasis level, (3) provide quantitative framework scaling plants order determine community productivity. Furthermore, review out integrating evolution lacking, therefore more attention needs devoted issue global research community.
