Thermal acclimation fails to confer a carbon budget advantage to invasive species over natives

This dataset originates from a two-year transplant experiment conducted across a temperature gradient in Europe (mean annual temperatures: 8.4–21.8 °C). It includes physiological measurements of one invasive palm species (Trachycarpus fortunei) and two co-occurring native species (Ilex aquifolium and Tilia cordata). The dataset captures plant acclimation responses to air temperature, focusing on photosynthetic and respiratory traits that influence carbon balance. Variables that can be extracted:

• Optimal temperature of photosynthesis (Topt)
• Photosynthetic rate at optimal temperature (Aopt)
• Thermal breadth of photosynthesis (T80)
• Respiration rate at 25 °C (R25)
• Temperature sensitivity of respiration (Q10) Raw data are reported for all species across multiple sites and time points, enabling assessment of their acclimation capacity to warming. The dataset supports comparisons of functional plasticity between an invasive species and native taxa, providing insights into climate responses and invasion ecology.
