Tree diversity has contrasting effects on predation rates by birds and arthropods on three broadleaved, subtropical tree species

Plant diversity is hypothesized to strengthen biological control by promoting top‐down pressure of predators on herbivores. However, studies on the effects of plant diversity on actual predation rates are still scarce, particularly in forest ecosystems. We analyzed the effect of tree species richness, and the potential influence of neighbor tree density, on predation rates of arthropods and birds on artificial clay caterpillars in a large‐scale...
