title: Integrating comparative functional response experiments into global change research.
abstract: There is a growing appreciation for the importance of non-consumptive effects in predator-prey interaction research, which can often outweigh the importance of direct feeding. Barrios-O'Neill et al. (2014) report a novel method to characterize such effects by comparing the functional response of native and introduced intermediate consumers in the presence and absence of a higher predator. The invader exhibited stronger direct feeding and was also more resistant to intimidation by the higher predator. This experimental framework may be incorporated into mainstream global change research, for example, to quantify the importance of non-consumptive effects for the success or failure of biological invasions.
