Study Search and Screening
To identify candidate studies we performed a systematic search of the
Web of Science Core Collection using the following search string:
predat* AND (parasit* OR pathogen*). This search identified 11,417
candidate studies. Abstracts were subsequently screened to determine if
they met three strict inclusion criteria: they must have (i) involved an
animal host/prey population, a predator population that kills and
consumes the host/prey, and a parasite that infects the host/prey; (ii)
observed multiple levels of predation pressure, and (iii) measured at
least one relevant parasite outcome (e.g. intensity or prevalence).
Based on abstract screening 256 studies were identified as potentially
meeting these three criteria, 50 of which were confirmed following
full-text screening (Supplementary Figure 1).
