Trophic compensation reinforces resistance: herbivory absorbs the increasing effects of multiple disturbances
Abstract Disturbance often results in small changes in community structure, but the probability of transitioning to contrasting states increases when multiple disturbances combine. Nevertheless, we have limited insights into the mechanisms that stabilise communities, particularly how perturbations c...
