In laboratory and field studies of the invasive ant Solenopsis invicta, ant nesting increases soil nitrate and ammonium, which is linked to enhanced plant growth and altered defense signaling.
- Why it matters: Ant nesting is known to engineer ecosystems, but how it reshapes mutualistic interactions among ants, plants, and herbivores remains unclear.
- What they did: The study measured soil nutrient changes and host plant hormonal signaling, finding elevated auxin alongside suppressed salicylic acid and jasmonate pathways, with reduced aphid defense responses.
- The result: Plants near ant nests support larger aphid populations that provide more carbohydrate rewards, augmenting ant colony survival and brood biomass, suggesting a nesting-associated feedback loop.
