Other claims from this paper (7)
- Intervention effect Locust herbivory reduced maternal fitness across the Brachypodium species complex, with magnitude depending on species and fitness component.
- Observation The results do not support enhanced herbivory resistance or tolerance in the allotetraploid lineage.
- Observation Plant damage in B. hybridum was comparable to that of one diploid parent, B. distachyon.
- Observation Diploid B. distachyon had higher tolerance than B. hybridum for two of three fitness estimators.
- Association Variation in herbivory resistance was associated with plant traits, particularly C:N ratio and silica content.
- Association In B. distachyon, tolerance was negatively associated with silica and water content.
- Mechanism The authors suggest the tolerance associations indicate allocation trade-offs between resistance- and tolerance-related traits.
