Hypothesis
Heat waves will limit the phenotypic growth of both Wedelia trilobata and Wedelia chinensis, but the extent of growth limitation will differ, with the invasive species potentially exhibiting greater tolerance.
Conclusion
The invasive Wedelia trilobata shows better growth and photosynthetic efficiency under heat wave conditions compared to the native Wedelia chinensis, suggesting a competitive advantage.
Supporting Evidence
- W. trilobata maintained higher photosynthetic efficiency and total biomass under heat wave conditions.
- W. chinensis focused more on root development and antioxidant protection, showing decreased total biomass.
- Heat waves are projected to become more frequent and intense with climate change.
Takeaway
This study found that the invasive plant Wedelia trilobata grows better than the native Wedelia chinensis during heat waves, which could help it take over more areas.
Methodology
The study compared the physiological and photosynthetic responses of both plant species under simulated heat wave conditions in a greenhouse.
Limitations
The study was conducted in a controlled environment, which may not fully replicate natural conditions.
