Intercropping functionally similar species reduces yield losses due to herbivory. A meta-analytical approach

Agroecosystem diversification is often implemented to diminish herbivory and reduce yield losses. However, increasing plant richness does not always reduce herbivory levels, so there is a need for better understanding which polyculture characteristics are effective in deterring herbivores. Here, we...
