Unpalatable plants induce a species-specific associational effect on neighboring communities

Abstract In grazing conditions, unpalatable species may induce either associational defense or neighbor contrast susceptibility in neighboring communities. Using surveys from eight grasslands, we tested whether various unpalatable species have the same impacts on neighboring communities in response...

Using surveys from eight grasslands, we tested whether various unpalatable species have the same impacts on neighboring communities in response to grazing.

Our results showed that, in the ungrazed grasslands, communities containing P. cancellata had lower biodiversity than communities without it.

Different responses of plant community vulnerability among the studied unpalatable plants might be due to herbivore different foraging decisions.
