Toxic cascades: multiple anthropogenic stressors have complex and unanticipated interactive effects on temperate reefs.

abstract：:The tortuosity of the track taken by an animal searching for food profoundly affects search efficiency, which should be optimised to maximise net energy gain. Models examining this generally describe movement as a series of straight steps interspaced by turns, and implicitly assume no turn costs. We used both empirica...
