Both the frequency of sesquiterpene-emitting individuals and the defense capacity of individual plants determine the consequences of sesquiterpene volatile emission for individuals and their neighbors in populations of the wild tobacco Nicotiana attenuata.

Real-time volatile emission kinetics reveal stress volatiles emitted from herbivore-damaged plants can sequentially prime and induce defense responses in undamaged plants following distinct temporal patterns.

The spatial interactions between humans, large carnivores and herbivores cascade down in a complex but predictable way to lower trophic levels affecting regeneration of tree species in a temperate forest.
A chewing herbivore induced WRKY transcription factor induces jasmonate-dependent defences and supresses gibbererellin-dependent growth, the latter of which renders rice plants more susceptible to secondary infestation by a piercing-sucking herbivore.
Floral scent and nectar are highly variable in natural populations and both traits can influence outcrossing rates differently for different pollinators and increase future herbivory.

Cytokinin-dependent manipulation of plant metabolism is a strategy employed not only by gallers and leaf-miners but also by a free-living insect, Tupiocoris notatus, which directly transfers cytokinins at feeding sites to manipulate its host plant.
Experimental Piper gardens across five neotropical sites reveal complex contingencies in the influence of species and population-level biodiversity on the flow of resources to insect herbivores and ecosystem resilience to changes in water availability.
An insect digestive enzyme metabolizes a plant defense compound and thereby modulates herbivore performance and host plant choice, which in turn may alter plant defense evolution in nature.
