Objects and exposures in paternal effect studies broken down by bibliometric cluster. Plots are based on 302 empirical studies included in the map and assigned to one of the three clusters (Med, Tox and EcoEvo). The size of the panels is proportional to the frequency of studies in a given category. Colour represents the category of experimental exposure (for the legend, see Fig. 2a). a Source of studied species, taxonomic group and category of paternal exposure. b Category of experimental exposure, information on maternal and offspring exposure to the same factor as the father
