Supplementary TABLE 4. STUDIES OF PREDATOR DIET CUE BY SYSTEM AND DIETARY DIFFERENCE.
Values are calculated from Supplementary TABLE 1. Columns indicate (from left to right) the total number of
investigations which measured each difference in a given system, the number of investigations which found a
response to a given dietary difference in that system, the number which did not find a response to the difference, and
the percentage of investigations (out of the total number for each system and difference) which found a response to
predator diet cues. The term investigation is used, rather than publication, as many articles investigated multiple
predator-prey interactions. Thus, the total number of predator diet investigations (200) is greater than the total
number of publications (107). * indicates categories which include the study by Nunes et al. 2013, which found
response differences in some of the studied prey species and not in others. Therefore, this study is counted as both a
yes and a no and the total number of studies (201) reflects this finding.
