Intraspecies differences in phenotypic plasticity: Invasive versus non-invasive populations of Ceratophyllum demersum

摘要: Abstract High phenotypic plasticity has been hypothesized to affect the invasiveness of plants, as high may enlarge breath environments in which plants can survive and reproduce. Here we compare invasive non-invasive populations same species response growth temperature. Populations submerged macrophyte Ceratophyllum demersum from New Zealand, where is introduced invasive, Denmark, native non-invasive, were grown a common garden setup at temperatures 12, 18, 25 35 °C. We that fitness-related traits like photosynthesis higher than population. The population acclimated elevated through increased rates (range: P amb : 8–452 μmol O 2  g −1  DM h ) relative 0.01–0.05 d associated regulations photosynthetic machinery. had lower acclimation potential 43–173 μmol O ; RGR: 0.01–0.03 d ), but was better acclimating cooler conditions by regulation light-harvesting complex. Hence, C.
