Above- and belowground herbivory jointly impact defense and seed dispersal traits in Taraxacum officinale [PDF]

open access: yes, 2014
Plants are able to cope with herbivores by inducing defensive traits or growth responses that allow them to reduce or avoid the impact of herbivores. Since above- and belowground herbivores differ substantially in life-history traits, for example feeding
