  1. Search time span was set until 2009, all document types were searched. Number of studies indicates the number of studies generated in the respective search query. For honeybees, all databases were accessed on 3 June 2017; three additionally found documents were relevant for the ERA. For earthworms, all databases were accessed on 11 August 2016; none of the additionally found documents was relevant for the ERA
