Specificity of extrafloral nectar induction by herbivores differs among nativ…

† Background and Aims: Invasive plants can be released from specialist herbivores and encounter novel generalists in their introduced ranges, leading to variation in defence among native and invasive populations. However, fewstudies have examined how constitutive and induced indirect defences change during plant invasion, especially during the juvenile stage. † Methods: Constitutive e…
