e0“Aphids broadly mirrored these effects on Si- plants, increasing colonization rates under eCO2 and performing much worse (reduced abundance and colonization) under eT when compared to ambient conditions”
e1“M. sativa growing in Si supplemented (Si+) and un-supplemented soil (Si-)”

- Intervention effect In Si- soils, elevated CO2 (+240ppm) stimulated M. sativa plant growth by 67%.
- Intervention effect In Si- soils, elevated CO2 stimulated M. sativa nodulation by 42%.
- Intervention effect In Si- soils, elevated temperature reduced M. sativa plant growth by 26%.
- Intervention effect In Si- soils, elevated temperature reduced M. sativa nodulation by 48%.
- Intervention effect Aphid abundance and colonization on Si- plants were reduced under elevated temperature compared with ambient conditions.
- Intervention effect Across all CO2 and temperature regimes, Si supplementation promoted M. sativa plant growth by 93%.
- Intervention effect Across all CO2 and temperature regimes, Si supplementation promoted M. sativa root nodulation by 50%.
- Intervention effect Acyrthosiphon pisum abundance declined sharply under elevated temperature.
- Intervention effect Acyrthosiphon pisum abundance was largely unaffected by Si supplementation.
- Recommendation The authors conclude Si supplementation offers potential to maintain legume productivity under predicted climate change without making legumes more susceptible to insect pests.
