Summary of literature survey
Our final data set included 98 studies and 891 effects (Fig. 1). While
most studies reported results from a single experiment, 21 studies
included two to four experiments, resulting in a total of 122
experiments. Host taxa included arthropods (n = 20 species, classes
Brachiopoda, Copepoda, Insecta, and Malacostraca), molluscs (n = 13
species, classes Bivalvia and Gastropoda), fish (n = 13 species),
amphibians (n = 21 species), and several vertebrates species (two bird,
one reptile, and one mammal) (Fig. S1a). Parasite taxa comprised viruses
(n = 37), bacteria (n = 14), fungi (n = 6), parasitic animals (n = 13,
helminths and myxozoan), and protozoans (n = 8) (Fig. S1b).
