Ecological predictors of plant responses to sequential herbivory: a meta‐analysis

open access: yesNew Phytologist, Volume 250, Issue 2, Page 1128-1140, April 2026.
Summary Plants evolved alongside herbivores for over 400 million years and show remarkable plasticity in responses to attack by multiple herbivores. However, it is often debated which herbivore traits predict plant responses and it is poorly understood how plant life‐history traits contribute to the variation observed in plant responses.
