Hamish S. Greig, Scott A. Wissinger and Angus R. McIntosh Top-down control of prey increases with drying disturbance in ponds: a consequence of non-consumptive interactions? Journal of Animal Ecology 82
Here it is shown that non-consumptive interactions in the diverse predator guilds of physically benign habitats reduce predation rates, resulting in an unexpected increase in top-down control with increasing disturbance. Therefore, considering changes in food-web complexity, especially the non-consumptive effects of top predators, is essential to understand species interactions across environmental gradients.
