Abstract
Predation intensity recorded from exposed prey communities at coastal sites across a latitudinal gradient spanning the subarctic to the tropics. Invertebrate communities developed under low predation for three or 12 months within cages. Mature prey communities were then exposed to ambient predation, with a high definition camera recording all predation events during the diurnal period over three days of exposure. This experiment provided an assessment of predation intensity (and predator identity) to complement predator exclusion experiments that measured impact of predators on prey community assembly. For a complete list of measurements, refer to the full dataset description in the supplemental file 'Dataset_description.pdf'. The most current version of this dataset is available at: https://www.bco-dmo.org/dataset/863158
