Other claims from this paper (7)
- Observation About 60% of the temperate European herbaceous species had naturalized in temperate regions.
- Observation Over 30% of the species had naturalized in tropical regions.
- Association Naturalized species showed consistently higher overall germinability than non-naturalized species.
- Association Naturalized species showed higher requirements for seed scarification than non-naturalized species.
- Association The extent of naturalization was positively but weakly related to higher germinability and to the same germination traits that distinguished naturalized from non-naturalized species.
- Mechanism The authors conclude that high germinability, low stratification requirements and responsiveness to scarification act as preadaptations that facilitate naturalization.
- Recommendation The authors conclude that standardized laboratory germination tests using seeds from native populations are a cost-effective tool for improving global risk assessments.
