Abstract
Plant Ecology Populations of invasive plant species are likely to grow more rapidly in a warming climate. To test this concept, Keller and Shea experimentally studied the growth and reproduction of the globally invasive thistle Carduus nutans in warmed plots. Both the temperature and the onset of the growing season were then manipulated. Their results and modeling show that plants reached reproductive maturity earlier and grew larger, which enabled the production of more seeds. Overall, the thistle's population growth rate was projected to increase by 15%, posing a further threat to agricultural production and food security in regions where it has already become invasive.
