Global Warming, Rising CO2 and Invasive Plants
- Global Warming, Rising CO2 and Invasive Plants. Dr. Lewis Ziska, Plant Physiologist, USDA Crop Systems and Global Change Lab
"... current levels of atmospheric CO2 are less than optimal for plant growth, ....
".... we have compared the potential response to recent and projected changes in carbon dioxide between invasive, noxious species and other plant groups, and assessed whether CO2 preferentially selects for such species within ecosystems. A synthesis of literature results
indicates that invasive, noxious weeds on the whole have a larger than expected growth increase to both recent and projected increases in atmospheric CO2 relative to other plant species. There is also evidence from a majority of studies, than rising CO2 can, in fact, preferentially select for invasive, noxious species within plant communities ..."
