Interactive effects of plant neighbourhood and ontogeny on insect herbivory and plant defensive traits

Abstract Plant ontogenetic stage and features of surrounding plant neighbourhoods can strongly influence herbivory and defences on focal plants. However, the effects of both factors have been assessed independently in previous studies. Here we tested for the independent and interactive effects of ne...
