Hypothesis
Is local adaptation in plants influenced by species, population, and habitat characteristics?
Conclusion
Local plants generally perform better than foreign plants, but local adaptation is less common than previously assumed.
Supporting Evidence
- Local plants performed better than foreign plants in 71.0% of the studied sites.
- Local adaptation was much more common in large populations than in small populations.
- Maladaptation occurred in only 3.3% of the cases.
Takeaway
Plants that grow in their home area usually do better than those from far away, but this doesn't happen as often as we thought, especially for small plant groups.
Methodology
A meta-analysis of 35 studies comparing local and foreign plant performance across 1032 pairwise comparisons.
Potential Biases
Potential bias due to the selection of studies that may favor pronounced local adaptation.
Limitations
The study primarily focused on herbaceous plants in temperate regions, which may limit the generalizability of the findings.
Participant Demographics
The study included 32 plant species from various habitats.
